Complete Guide to Filing Form 1095-C for Seasonal Employees

Introduction: Understanding 1095-C Requirements for Seasonal Employees

Filing Form 1095-C for seasonal employees presents unique challenges for employers navigating ACA compliance. Seasonal workers are hired into positions that, by their nature, operate for only part of the year, such as holiday retail staff, summer camp counselors, harvest workers, ski resort employees, or tax season preparers. The temporary nature of these positions creates complex reporting requirements under the Affordable Care Act, as employers must determine whether seasonal employees qualify as full-time, when coverage offers are required, and which Line 14 and Line 16 codes properly reflect each worker's status. Errors in reporting 1095-C seasonal employees can result in IRS penalties up to $330 per form or trigger employer shared responsibility assessments of $4,350 per affected employee for 2025.

The complexity of handling seasonal employees on Form 1095-C stems from the intersection of two distinct ACA provisions: the seasonal employee exception for determining Applicable Large Employer (ALE) status and the seasonal worker classification for determining individual full-time status. These are separate rules that apply at different stages of the compliance process. Additionally, many employers confuse seasonal employees with variable hour employees, leading to incorrect coding and potential penalty exposure. A seasonal employee working 40 hours per week during their employment period may still qualify for special treatment under ACA regulations, but only if their position meets specific criteria established by the IRS.

This comprehensive guide explains everything you need to know about completing Form 1095-C for seasonal employees. We will cover how to properly classify seasonal workers under ACA regulations, understand the difference between the seasonal employee exception and seasonal worker classification, implement measurement periods for seasonal employees, determine when coverage offers are required, select the correct Line 14 and Line 16 codes, and navigate the unique scenarios that arise when employees work seasonally. Whether you operate a retail business with holiday rush hiring, an agricultural operation with harvest workers, or any business with predictable seasonal staffing patterns, this article provides the detailed guidance you need for accurate ACA reporting.

What Is a Seasonal Employee Under the ACA?

The IRS Definition of Seasonal Employee

Under IRS regulations, a seasonal employee for purposes of the look-back measurement method is an employee who is hired into a position for which the customary annual employment is six months or less. This classification is based on the nature of the position itself, not on how long any particular employee actually works. The determination focuses on whether the position has historically been, or is reasonably expected to be, a position that operates for six months or less each year. Industries with clearly defined busy seasons, such as retail during holidays, agriculture during planting or harvest, or tourism during summer or winter resort seasons, typically have positions that qualify as seasonal.

The key distinction is that seasonal employee status relates to the position's characteristics, not the individual worker's tenure. An employee hired into a seasonal position on March 1 who works through October 31 (eight months) would still be classified as a seasonal employee if the position itself customarily operates for six months or less annually. Conversely, an employee hired for what was intended to be a short-term project but who ends up working year-round would not qualify as a seasonal employee because the position was not customary annual employment of six months or less.

Factors the IRS examines: Whether the position has historically operated for six months or less, whether the employer's industry has recognized seasonal patterns, whether similar positions at comparable employers operate seasonally, and whether the position's responsibilities are tied to seasonal business demands rather than year-round operational needs.

Seasonal Employee Exception vs. Seasonal Worker Classification

The ACA contains two separate provisions involving seasonal workers that serve different purposes. Understanding the distinction is essential for proper 1095-C seasonal employees reporting:

Provision Purpose Definition Application
Seasonal Employee Exception (ALE Status) Determines if employer is an Applicable Large Employer Employee who works 120 days or less during the year Can exclude seasonal employees when counting toward 50-employee threshold
Seasonal Worker Classification (Full-Time Status) Determines individual employee full-time status Employee in position that customarily operates 6 months or less Can use look-back measurement method like variable hour employees

Critical distinction: The seasonal employee exception (120-day rule) applies only when determining whether an employer has 50 or more full-time equivalent employees and thus qualifies as an Applicable Large Employer. The seasonal worker classification (six-month position rule) applies when determining how to treat individual employees for full-time status determination and 1095-C reporting. An employer may use the seasonal employee exception to determine ALE status but must still properly report seasonal workers on Form 1095-C if they qualify as full-time.

Seasonal Employees vs. Variable Hour Employees

While both seasonal employees and variable hour employees can use the look-back measurement method, they are distinct classifications with different criteria:

Classification Definition Key Characteristic 1095-C Treatment
Seasonal Employee Position customarily operates 6 months or less annually Predictable employment period based on seasonal demand Use measurement method; report based on hours during measurement
Variable Hour Employee Cannot determine at hire if employee will average 30+ hours Unpredictable hours within ongoing employment Use measurement method; report based on hours during measurement
Seasonal Variable Hour Both conditions apply (seasonal position with unpredictable hours) Short-term position with fluctuating schedule Either classification allows measurement method use

An employee can be both seasonal and variable hour if hired into a position that customarily operates six months or less AND the employer cannot determine at hire whether the employee will average 30 hours per week. However, it only takes one classification to permit use of the look-back measurement method.

How Seasonal Employees Affect Applicable Large Employer Status

The 50-Employee Threshold and Seasonal Workers

Before addressing individual 1095-C reporting, employers must first determine whether they qualify as an Applicable Large Employer (ALE). An employer is an ALE if it employed an average of at least 50 full-time employees (including full-time equivalents) during the preceding calendar year. The seasonal employee exception allows employers to exclude seasonal employees from this count under specific circumstances.

The seasonal employee exception for ALE determination:

  • An employer exceeding 50 full-time employees for 120 days or fewer during the calendar year
  • AND the employees in excess of 50 during that period were seasonal employees
  • THEN the employer is NOT considered an ALE for the following year

For this exception, a seasonal employee is one who performs labor or services on a seasonal basis as defined by the Department of Labor (including retail workers employed during holiday seasons and agricultural workers) AND the employee works for the employer 120 days or fewer during the calendar year. This is the 120-day definition, which differs from the six-month position definition used for full-time status determination.

Example: A retail employer has 40 full-time year-round employees and hires 25 seasonal employees for the November-December holiday season (approximately 60 days). During November and December, the employer has 65 full-time employees, exceeding 50. However, because the employer exceeded 50 for only about 60 days, and the excess employees were seasonal, the employer may qualify for the seasonal employee exception and would NOT be an ALE for the following year.

When the Seasonal Employee Exception Does Not Apply

The seasonal employee exception does not apply when:

  • The employer exceeds 50 full-time employees for more than 120 days during the year
  • The employees causing the excess are not seasonal employees (e.g., permanent hires)
  • Seasonal employees work more than 120 days during the year
  • The employer's base workforce (excluding seasonal workers) exceeds 50

If an employer is determined to be an ALE, all full-time employees (including seasonal employees who qualify as full-time) must be offered coverage and reported on Form 1095-C. The seasonal employee exception only affects ALE status determination, not reporting requirements once ALE status is established.

The Look-Back Measurement Method for Seasonal Employees

Why the Measurement Method Applies to Seasonal Workers

The ACA provides the look-back measurement method for seasonal employees because the temporary nature of their employment makes it difficult to determine full-time status at the time of hire. Even though a seasonal employee may be hired to work full-time hours during their employment period, the limited duration of the position creates uncertainty about whether they will meet the annual full-time threshold. The measurement method allows employers to track hours over an extended period, determine full-time status based on actual averages, and provide stability in coverage determinations.

Initial Measurement Period for New Seasonal Employees

When a seasonal employee is hired, the employer begins tracking their hours during an initial measurement period. This period can be anywhere from 3 to 12 months in length. During this time, the employer records the employee's hours of service to calculate their average weekly hours, including any weeks where the employee performed zero hours (which counts as zero hours in the average calculation).

Key rules for initial measurement periods with seasonal employees:

  • The measurement period must be at least 3 months but no longer than 12 months
  • The measurement period can begin on the employee's start date, the first of the month following hire, or the first day of the payroll period including the start date
  • Different initial measurement periods can be used for different categories of employees (e.g., seasonal vs. year-round) as long as the categories are reasonable and consistently applied
  • Hours are calculated using 130 hours per month for full-time equivalency (averaging 30 hours per week)

Example: A ski resort hires a seasonal employee on November 15, 2024. The employer uses a 12-month initial measurement period starting the first of the month following hire (December 1, 2024 through November 30, 2025). The employee works 900 hours from December through March, then does not work April through November. Total hours: 900 divided by 52 weeks = 17.3 hours per week average. Result: Employee is NOT full-time (under 30 hours average). The seasonal nature of employment resulted in a low annual average despite working full-time hours during the actual working season.

Administrative Period Between Measurement and Stability

The administrative period is the time between the end of a measurement period and the beginning of the associated stability period. This period allows employers time to calculate hours, determine full-time status, notify employees, and enroll qualifying employees in coverage. The combined length of the initial measurement period plus the administrative period cannot exceed 13 months plus a fraction of a month (from the employee's start date to the first day of the following calendar month).

For seasonal employees who may not return until the next season, the administrative period provides critical flexibility. The employer can complete the full-time determination during the off-season and be prepared to offer coverage (if required) when the employee returns.

Stability Period for Seasonal Employees

Once the initial measurement period ends and the administrative period concludes, the employee enters their stability period. The employee's full-time status is locked in for this entire period based on the measurement period results.

Stability period rules for seasonal employees:

  • If determined full-time: stability period must be at least 6 consecutive months and no shorter than the initial measurement period
  • If determined not full-time: stability period can match the measurement period length
  • During the stability period, status does not change regardless of actual hours worked (or not worked)
  • A seasonal employee who returns after being off several months remains in their stability period status

Important consideration: A seasonal employee determined to be full-time based on measurement period hours must be offered coverage during the entire stability period, even if they are not working during part of that period. However, months where the employee is not employed would be reported with code 2A (employee not employed) on Line 16.

How Measurement Period Results Affect 1095-C Reporting for Seasonal Employees

Scenario 1: Seasonal Employee Determined Full-Time

When a seasonal employee averages 30 or more hours per week during the measurement period, they are determined to be full-time for the subsequent stability period. This is less common for seasonal employees because their limited working months often result in lower annual averages, but it can occur when seasonal employees work significant overtime during their season or when the measurement period aligns favorably with their working season.

For seasonal employees determined full-time:

  • Coverage offer required: The employer must offer minimum essential coverage to the employee (and their dependents) for the entire stability period
  • Form 1095-C required: The employee needs a 1095-C for any year in which they are full-time for at least one month
  • Line 14 codes: Report the coverage offer made (1A, 1B, 1C, 1D, 1E, or 1F depending on the offer type)
  • Line 15: Enter the employee's monthly share of the lowest-cost self-only minimum value coverage
  • Line 16 codes: Use 2A for months not employed, or 2C if enrolled, or safe harbor codes (2F, 2G, 2H) if applicable

Scenario 2: Seasonal Employee Determined Not Full-Time

More commonly, seasonal employees average fewer than 30 hours per week during the measurement period and are determined NOT full-time for the subsequent stability period. This typically occurs because their limited working months result in a low annual hour average, even if they worked full-time hours during their actual employment period.

For seasonal employees determined not full-time:

  • No coverage offer required: The employer is not required to offer coverage during the stability period
  • Form 1095-C: Only required if the employee was full-time for at least one month during the tax year (which may include months in a prior stability period)
  • Line 14: Use code 1H (no offer of coverage) for months when no coverage was offered
  • Line 16: Use code 2B (not full-time) for months in a non-full-time stability period when employed, or 2A when not employed

Scenario 3: Seasonal Employee During Initial Measurement Period

During the initial measurement period (before full-time status is determined), the seasonal employee is in a limited non-assessment period. This is critical for 1095-C seasonal employees reporting:

  • No penalty exposure: The employer is not subject to the employer shared responsibility penalty for this employee during the initial measurement period
  • Line 14: Report what coverage was actually offered (or 1H if no coverage offered)
  • Line 16: Use code 2D (employee in limited non-assessment period) for months during the initial measurement period and administrative period
  • Coverage offer optional: Employers may choose to offer coverage during this period but are not required to

Completing Part II of Form 1095-C for Seasonal Employees

Line 14: Offer of Coverage Codes

Line 14 of Form 1095-C reports what coverage was offered to the employee each month. For 1095-C seasonal employees, the correct Line 14 code depends on the employee's period status, employment status, and actual coverage offers. The Line 14 codes commonly used for seasonal employees include:

Code Description Seasonal Employee Scenario
1H No offer of coverage Initial measurement period, non-full-time stability period, or months not employed
1A Qualifying Offer Full-time stability period when qualifying coverage offered
1E Minimum value coverage to employee, spouse, and dependents Full-time stability period when MV coverage offered to all
1B Minimum value coverage to employee only Full-time stability period when MV coverage offered to employee only
1G Offer to employee who was not full-time and did not enroll When voluntary coverage offered during measurement period or non-full-time stability period

Line 15: Employee Share of Premium

Line 15 reports the employee's monthly share of the lowest-cost self-only minimum value coverage. For seasonal employees, follow these rules:

  • Initial measurement period (code 2D on Line 16): Leave Line 15 blank if no coverage offered; enter amount if coverage was offered
  • Full-time stability period: Enter the monthly premium amount for the lowest-cost self-only MV plan
  • Non-full-time stability period (code 2B on Line 16): Leave blank if no coverage offered; enter amount if voluntary coverage offered
  • Months not employed (code 2A on Line 16): Leave blank
  • Code 1A months: Leave blank (affordability is built into the Qualifying Offer definition)

Line 16: Safe Harbor and Period Status Codes

Line 16 is especially important for 1095-C seasonal employees because it reports the limited non-assessment period (code 2D) that protects employers from penalties during measurement periods, as well as months where the employee is not working. The Line 16 codes most relevant for seasonal employees are:

Code Description When to Use for Seasonal Employees
2A Employee not employed during the month Critical for seasonal employees: Use for off-season months when employee is not working
2D Employee in limited non-assessment period Months during the initial measurement period and administrative period when employed
2B Employee not full-time during the month Stability period months when determined not full-time and employed
2C Employee enrolled in coverage Any month when employee enrolled in employer coverage
2F W-2 safe harbor Full-time stability months when W-2 affordability safe harbor applies
2G Federal poverty line safe harbor Full-time stability months when FPL safe harbor applies
2H Rate of pay safe harbor Full-time stability months when rate of pay safe harbor applies

Understanding Code 2A for Seasonal Employees

Code 2A is particularly important for seasonal employee reporting because it properly reflects months where the employee is not working. For seasonal employees, extended periods of non-employment are expected and normal. Code 2A indicates the employee was not employed during the month, which relieves the employer of any coverage offer requirement for that month. The code applies regardless of whether the employee is in a full-time or non-full-time stability period. Code 2A and code 2D cannot be used for the same month. If an employee is in their initial measurement period but was not employed for a particular month (e.g., they started mid-measurement period), use 2A for months before employment began.

Timeline Examples: Reporting Seasonal Employees Across Multiple Years

Example 1: Seasonal Retail Employee (Holiday Season)

An employer uses a 12-month initial measurement period starting the first of the month following hire, with a 2-month administrative period.

Facts:

  • Employee hired: November 1, 2024 for holiday retail position
  • Initial measurement period: December 1, 2024 through November 30, 2025
  • Administrative period: December 1, 2025 through January 31, 2026
  • Initial stability period: February 1, 2026 through January 31, 2027
  • Employment dates: November 1 - December 31, 2024 (worked 35 hours/week)
  • Total hours in measurement period: 400 hours (December 2024 only, since measurement starts December 1)
  • Average: 400 hours / 52 weeks = 7.7 hours per week. Result: NOT full-time

2024 Form 1095-C Reporting (November-December 2024):

Month Period Status Line 14 Line 15 Line 16
January-October Not employed 1H (blank) 2A
November Employed (before measurement period) 1H (blank) 2D
December Initial measurement period 1H (blank) 2D

2025 Form 1095-C Reporting (January-December 2025):

Month Period Status Line 14 Line 15 Line 16
January-November Initial measurement period (not employed) 1H (blank) 2A
December Administrative period (not employed) 1H (blank) 2A

Example 2: Summer Camp Counselor (Returns Annually)

A summer camp hires a counselor who returns each summer. The camp uses a 12-month standard measurement period (calendar year) with a 1-month administrative period.

Facts:

  • Original hire date: June 1, 2023
  • 2024 employment: June 1 - August 15, 2024 (40 hours/week)
  • Standard measurement period: January 1 - December 31, 2024
  • Administrative period: January 2025
  • Standard stability period: February 1, 2025 - January 31, 2026
  • Total hours in 2024 measurement period: 440 hours (11 weeks at 40 hours)
  • Average: 440 hours / 52 weeks = 8.5 hours per week. Result: NOT full-time

2024 Form 1095-C Reporting:

Month Status Line 14 Line 15 Line 16
January Prior stability period (not FT, not employed) 1H (blank) 2A
February-May Standard measurement (not employed) 1H (blank) 2A
June-August Standard measurement (employed) 1H (blank) 2B
September-December Standard measurement (not employed) 1H (blank) 2A

Note: During the standard measurement period for ongoing employees, use 2B (not 2D) when the employee is employed but not full-time. Code 2D applies only during the initial measurement period for new employees.

Example 3: Seasonal Agricultural Worker Who Becomes Full-Time

An agricultural employer hires a seasonal worker who ends up working enough hours to be determined full-time.

Facts:

  • Employee hired: March 1, 2024
  • Initial measurement period: April 1, 2024 through March 31, 2025
  • Employment: March 2024 - October 2024 (8 months at 50 hours/week average)
  • Total hours: 1,733 hours over 34.7 weeks
  • Average: 1,733 / 52 weeks = 33.3 hours per week. Result: FULL-TIME
  • Administrative period: April 1 - May 31, 2025
  • Stability period: June 1, 2025 - May 31, 2026

2025 Form 1095-C Reporting (with full-time stability period starting June):

Month Status Line 14 Line 15 Line 16
January-March Initial measurement (not employed) 1H (blank) 2A
April-May Administrative period (not employed) 1H (blank) 2A
June-December Full-time stability (not employed off-season) 1E $150.00 2A

Key insight: Even though the employee is in a full-time stability period, coverage is offered (Line 14 = 1E) but the employee is not employed (Line 16 = 2A). The employer satisfies its coverage offer obligation by offering coverage, even though the employee cannot enroll because they are not working. When the employee returns to work in 2026, they must be offered coverage immediately.

Special Rules for Rehired Seasonal Employees

The 13-Week Rule (26 Weeks for Educational Organizations)

When a seasonal employee terminates and is later rehired, special rules determine whether the employer can treat them as a new employee (starting a new initial measurement period) or must treat them as an ongoing employee (continuing their existing measurement/stability periods).

Break in service rules:

  • If break in service is less than 13 weeks (26 weeks for educational organizations): Employee continues existing measurement/stability period status
  • If break in service is 13 weeks or more (26 weeks for educational organizations): Employer may treat as new employee with new initial measurement period
  • Alternative rule: If break in service exceeds the employee's prior employment duration and is at least 4 weeks, employer may treat as new employee

Example: A seasonal retail employee works November 15 - January 15 (approximately 2 months) and then returns the following November. The break in service is approximately 10 months, which exceeds 13 weeks. The employer may treat this employee as a new employee and start a new initial measurement period.

Rule of Parity

The rule of parity provides an alternative way to treat a returning employee as a new hire. If the employee's break in service is at least 4 weeks AND the break is longer than the employee's prior period of employment, the employer may treat the employee as a new hire.

Example: An employee works for 6 weeks, then has a 7-week break before returning. Under the rule of parity, the employer may treat this employee as a new hire because the break (7 weeks) exceeded the prior employment (6 weeks) and was at least 4 weeks. This can be useful for very short-term seasonal positions.

Common Mistakes When Reporting Seasonal Employees on 1095-C

Mistake 1: Confusing the Two Seasonal Employee Definitions

Employers frequently confuse the seasonal employee exception for ALE determination (120-day rule) with the seasonal worker classification for full-time status (6-month position rule). These are separate rules. An employer may use the 120-day seasonal employee exception to avoid ALE status, but once determined to be an ALE, must apply the 6-month seasonal worker rules for individual employee reporting. Mixing up these definitions leads to incorrect classifications and coding.

Mistake 2: Using Code 2D When Code 2A Applies

Code 2D (limited non-assessment period) should only be used when the employee is employed during their initial measurement period. If the employee is not employed during a month (off-season), use code 2A regardless of the measurement period status. Some employers incorrectly use 2D for all months during the measurement period, even when the employee wasn't working.

Mistake 3: Not Offering Coverage During Full-Time Stability Period

If a seasonal employee is determined full-time based on measurement period hours, coverage must be offered during the entire stability period. Even if the employee is not currently working, the employer must have coverage available and offer it when the employee returns. Failing to offer coverage when the employee returns to work can trigger employer shared responsibility penalties.

Mistake 4: Incorrectly Calculating Average Hours

When calculating average weekly hours for seasonal employees, divide total hours by the number of weeks in the measurement period (not just the weeks worked). A seasonal employee who works 1,000 hours from June through August has an average of 1,000 / 52 = 19.2 hours per week (not 1,000 / 13 = 77 hours per week). Using the wrong denominator results in incorrect full-time determinations.

Mistake 5: Treating All Seasonal Workers the Same

Not all seasonal workers have the same status. Some may be clearly seasonal (6-month position), some may be variable hour, some may be both, and some may actually be full-time employees who happen to work during a busy season. Each category requires proper classification at hire based on facts and circumstances.

Penalties for Incorrect Seasonal Employee Reporting

Information Return Penalties

Errors on 1095-C seasonal employees forms can result in IRS information return penalties assessed per form:

Correction Timing Penalty Per Form (2025) Maximum Annual Penalty
Within 30 days of deadline $60 $630,500
By August 1 $130 $1,891,500
After August 1 $330 $3,783,000
Intentional disregard $660+ No cap

Employer Shared Responsibility Penalty

More significant than information return penalties, incorrect classification of seasonal employees or failure to offer coverage to full-time seasonal workers during their stability period can trigger the employer shared responsibility penalty (ESRP). If a full-time employee is not offered coverage and obtains subsidized Marketplace coverage, the employer may receive Letter 226-J proposing Penalty A of $2,900 per full-time employee (minus 30) or Penalty B of $4,350 per affected employee. Proper use of code 2D during initial measurement periods and code 2A for non-employment months provides protection from these penalties.

Deadlines for Seasonal Employee 1095-C Forms

Employee Furnishing Deadline

All employees who were full-time for any month during the tax year must receive their Form 1095-C by the furnishing deadline. For tax year 2025 forms, the deadline to furnish to employees is March 3, 2026. This includes seasonal employees who had any full-time months (including stability period months based on prior measurement periods). For seasonal employees who may have left the company, employers should mail the 1095-C to the employee's last known address.

IRS Filing Deadline

Forms 1095-C must be filed with the IRS by March 31, 2026 (electronic filing) for tax year 2025. The forms are filed with Form 1094-C as the transmittal. Employers can request an automatic 30-day extension using Form 8809, but extensions do not extend the employee furnishing deadline.

Frequently Asked Questions About 1095-C for Seasonal Employees

What makes an employee "seasonal" under the ACA?

An employee is considered seasonal for the look-back measurement method if hired into a position for which the customary annual employment is six months or less. This determination is based on the nature of the position itself, not how long a particular employee works. Industries with recognized busy seasons, such as retail holidays, agricultural harvest, or summer tourism, typically have qualifying seasonal positions.

Do I need to file a 1095-C for seasonal employees who only worked a few months?

A 1095-C is required only if the employee was considered full-time for ACA purposes for at least one month during the tax year. If a seasonal employee was in their initial measurement period (code 2D) or was determined not full-time (code 2B), and had no full-time months, a 1095-C may still be required depending on reporting thresholds. When in doubt, file the form to ensure compliance.

What code do I use for months when the seasonal employee isn't working?

Use code 2A (employee not employed during the month) on Line 16 for any month when the seasonal employee was not employed, regardless of their measurement or stability period status. This code indicates the employee was not on your payroll for that month.

If a seasonal employee works 40 hours per week during their season, are they full-time?

Not necessarily. Full-time status under the look-back measurement method is determined by averaging hours over the entire measurement period. If a seasonal employee works 40 hours per week for 3 months (520 hours) but the measurement period is 12 months, their average is only 520 / 52 = 10 hours per week, which is not full-time. The short duration of seasonal employment often results in not full-time status despite working full-time hours during the actual working period.

Can I treat a returning seasonal employee as a new hire?

Yes, if the break in service meets certain thresholds. If the seasonal employee was not employed for 13 weeks or more (26 weeks for educational organizations), you may treat them as a new employee with a new initial measurement period. Alternatively, under the rule of parity, if the break was at least 4 weeks and longer than the prior employment period, you may treat them as a new hire.

What's the difference between the seasonal employee exception and seasonal worker rules?

The seasonal employee exception (120-day rule) determines whether an employer is an Applicable Large Employer by allowing exclusion of seasonal workers from the 50-employee count. The seasonal worker classification (6-month position rule) determines how to treat individual employees for full-time status and 1095-C reporting. They serve different purposes and have different definitions.

Do I need to offer coverage to seasonal employees during their off-season?

If a seasonal employee is determined full-time based on their measurement period, you must have coverage available to offer during the entire stability period. However, if the employee is not employed during the off-season (Line 16 = 2A), they typically cannot enroll. The key is having coverage available to offer when they return to work.

How do I handle a seasonal employee who becomes a permanent employee?

If a seasonal employee transitions to a permanent, clearly full-time position, treat them as a full-time employee from the date of transition. Complete their current measurement period for ACA tracking purposes, but offer coverage by the first day of the fourth month following the change to a full-time position (or sooner if your plan requires).

What if our seasonal employees work different schedules each year?

The seasonal classification is based on the position, not individual employee patterns. If the position itself customarily operates six months or less annually, employees in that position are seasonal. Variations in individual schedules don't change the position's classification, but may affect the employee's hours calculation during measurement periods.

Can seasonal employees be offered coverage voluntarily?

Yes. Employers may offer coverage to seasonal employees during their initial measurement period or during non-full-time stability periods even when not required. This is reported with appropriate Line 14 codes (typically 1G if the employee is not full-time and doesn't enroll). Voluntary coverage offers can improve employee relations and retention for valued seasonal workers.

How BoomTax Simplifies 1095-C Reporting for Seasonal Employees

Managing Form 1095-C for seasonal employees requires tracking employment periods, calculating measurement period averages, determining full-time status across multiple seasons, and selecting proper codes for employed and non-employed months. BoomTax streamlines this complex process with specialized features designed for ACA compliance:

Conclusion: Mastering 1095-C Reporting for Seasonal Employees

Accurately completing Form 1095-C for seasonal employees requires understanding the distinct ACA provisions affecting seasonal workers, properly classifying employees based on position characteristics, implementing measurement periods that account for off-season gaps, and applying the correct codes for both employed and non-employed months. The key insights are that seasonal employee status is determined by the position (six-month rule), not the individual; that average hours must be calculated over the entire measurement period including zero-hour weeks; and that code 2A properly reflects off-season months when the employee is not working.

Key takeaways for 1095-C seasonal employees:

  • Position-based classification: A seasonal employee is in a position that customarily operates six months or less annually
  • Two separate rules: The seasonal employee exception (120 days for ALE status) differs from seasonal worker classification (6-month position for full-time determination)
  • Measurement period averaging: Calculate hours over the full measurement period, including weeks with zero hours during off-season
  • Use code 2A for non-employment: Months when the seasonal employee is not working use code 2A on Line 16
  • Use code 2D during initial measurement: Apply code 2D only for months when the employee is employed during their initial measurement period
  • Full-time status can occur: Seasonal employees working extensive hours may be determined full-time based on annual averages
  • Coverage during stability: If determined full-time, coverage must be available during the entire stability period, including when returning to work
  • Break in service rules: Breaks of 13+ weeks (or 26+ for educational organizations) allow treating returning workers as new hires
  • Track hours accurately: Proper full-time determination depends on complete hour records during measurement periods
  • File by deadlines: Furnish forms to employees by March 3, 2026 and file with IRS by March 31, 2026 (for tax year 2025)

By following the guidance in this article and using tools like BoomTax to automate seasonal employee tracking and code selection, you can ensure accurate 1095-C forms for your seasonal workforce while maintaining full compliance with ACA requirements.
