Complete Guide to Filing Form 1095-C for New Hires

Introduction: Why Reporting New Hires on Form 1095-C Requires Special Attention

Filling out Form 1095-C for new hires presents unique challenges that differ significantly from reporting on long-term employees. When a new employee joins your organization, you must navigate complex IRS rules about waiting periods, initial measurement periods, and limited non-assessment periods. Getting these details wrong can result in IRS penalty assessments reaching $330 per form or trigger the employer shared responsibility penalty of up to $4,350 per affected employee. Understanding how to properly complete 1095-C for new hires is essential for every Applicable Large Employer (ALE).

The complexity of reporting 1095-C new hires stems from the fact that employers cannot immediately determine whether a newly hired employee will become full-time. The Affordable Care Act's 30-hour rule defines full-time status, but for new employees without an established work history, employers must use measurement periods to make this determination. During the time between hiring and the determination of full-time status, special reporting codes apply. Many employers make costly mistakes by using incorrect Line 14 codes or failing to properly claim the limited non-assessment period relief on Line 16.

This comprehensive guide walks you through every aspect of completing Form 1095-C for new hires. We will explain how to determine whether a new employee is reasonably expected to be full-time, how to use initial measurement periods for variable-hour and seasonal employees, what codes to use during waiting periods, and how to handle employees who become full-time mid-year. Whether you are an HR professional, benefits administrator, or business owner managing ACA compliance, this article provides the detailed guidance you need to report new employees correctly.

Understanding New Hire Categories Under the ACA

Why Employee Classification Matters for 1095-C Reporting

Before you can correctly complete 1095-C for new hires, you must understand how the ACA classifies new employees. The IRS recognizes three primary categories of new hires, and the category determines which reporting rules and codes apply. Misclassifying an employee at the time of hire can lead to incorrect 1095-C reporting throughout the year and potential ACA penalties.

The three new hire categories are:

Category Definition Measurement Period Required?
Full-Time Employee Reasonably expected to average 30+ hours/week at hire No - immediately subject to coverage offer requirement
Variable-Hour Employee Cannot reasonably determine at hire if they will average 30+ hours/week Yes - use initial measurement period
Seasonal Employee Hired for position customarily lasting 6 months or less Yes - use initial measurement period

The classification must be made based on the facts and circumstances at the time of hire. Employers cannot artificially classify an employee as variable-hour simply to delay offering coverage. The IRS examines factors such as the job position's typical hours, whether similar positions are full-time, any prior employment history with the employer, and the reasonable expectation of the employee's future hours.

Full-Time New Hires: Immediate Reporting Requirements

When you hire an employee who is reasonably expected to work full-time (averaging 30 or more hours per week), the ACA's employer mandate applies immediately. This means you must offer minimum essential coverage within any applicable waiting period (maximum 90 days) or face potential penalties. For 1095-C new hires in this category, reporting begins with the first full month of employment.

Examples of employees classified as full-time at hire:

  • Salaried employees hired for exempt positions with no hour limits
  • Hourly employees hired for positions that regularly work 35+ hours per week
  • Managers and supervisors in positions that historically require full-time hours
  • Employees replacing a departed full-time worker in the same role

For these employees, you cannot use the initial measurement period. Instead, you must offer coverage by the end of any waiting period (no later than the first day of the fourth calendar month after hire for a 90-day waiting period). The 1095-C will show the offer of coverage or the appropriate Line 16 code for the limited non-assessment period during the waiting period.

Variable-Hour and Seasonal New Hires: Initial Measurement Period

For new employees whose full-time status cannot be reasonably determined at hire, employers may use an initial measurement period to track hours and make the determination. This applies to 1095-C new hires classified as variable-hour or seasonal employees. During the initial measurement period, you are not required to offer coverage to these employees, and special reporting codes apply.

How the initial measurement period works:

  • Duration: Between 3 and 12 months (employer chooses, but must be consistent)
  • Start date: Can begin on the first of the month following hire or on the hire date itself
  • Purpose: Track hours worked to determine if the employee averages 30+ hours/week
  • Administrative period: Up to 90 days after the measurement period ends to enroll qualifying employees

If the employee averages 30+ hours during the initial measurement period, they must be offered coverage for a stability period of at least the same length as the measurement period (minimum 6 months). If they do not average 30+ hours, you are not required to offer coverage during the stability period. Either way, the employee's Form 1095-C must accurately reflect their status during each month of the year.

Completing Part II of Form 1095-C for New Hires

Line 14: Offer of Coverage Codes for New Employees

Line 14 of Form 1095-C reports what coverage was offered to the employee each month. For 1095-C new hires, the correct Line 14 code depends on whether coverage was offered, when the employee became eligible, and what type of coverage was available. The Line 14 codes commonly used for new hires include:

Code Description New Hire Scenario
1A Qualifying Offer (coverage to employee, spouse, dependents meeting affordability) Full-time new hire after waiting period ends
1E Minimum value coverage to employee, spouse, and dependents Full-time new hire after waiting period when not using qualifying offer
1B Minimum value coverage to employee only When coverage is offered only to the employee
1C Minimum value coverage to employee; minimum essential coverage to dependents Coverage offered to employee and children but not spouse
1H No offer of coverage During initial measurement period for variable-hour employees; before coverage offered

Critical point for new hires: During months when no coverage was offered (such as during a waiting period or initial measurement period), use code 1H. Many employers incorrectly leave Line 14 blank or use other codes. Code 1H explicitly indicates that no offer was made, which is accurate for new employees who have not yet become eligible for coverage.

Line 15: Employee Share of Premium for New Hires

Line 15 reports the employee's monthly share of the lowest-cost self-only minimum value coverage. For 1095-C new hires, this line is completed only for months when coverage was offered. During months with code 1H on Line 14 (no offer), Line 15 is left blank.

Line 15 guidance for new hires:

  • Months before coverage offered: Leave Line 15 blank
  • Month coverage becomes effective: Enter the monthly premium amount
  • Code 1A months: Leave blank (affordability is built into the code definition)
  • Other offer codes (1B-1E): Enter the employee's monthly premium share

For mid-month starts, report the full monthly premium amount if coverage was offered for any part of the month. The IRS does not prorate Line 15 amounts—report the standard monthly employee contribution.

Line 16: Safe Harbor and Other Codes for New Employees

Line 16 is where 1095-C new hires reporting becomes most complex. This line reports applicable safe harbors, limited non-assessment period relief, and enrollment status. The Line 16 codes most relevant for new hires are:

Code Description When to Use for New Hires
2A Employee not employed during the month Months before hire date; months after termination
2B Employee not full-time during the month Part-time employees; during initial measurement period for variable-hour employees who are not yet determined full-time
2C Employee enrolled in coverage Months when the new hire actually enrolled in offered coverage
2D Employee in limited non-assessment period (waiting period) During the 90-day waiting period for full-time new hires
2E Multiemployer interim rule relief For employers contributing to multiemployer plans
2F W-2 safe harbor When coverage offered is affordable based on W-2 wages
2G Federal poverty line safe harbor When coverage is affordable based on FPL calculation
2H Rate of pay safe harbor When coverage is affordable based on rate of pay

Understanding Limited Non-Assessment Period Relief for New Hires

The limited non-assessment period is a critical concept for 1095-C new hires. It provides relief from employer shared responsibility penalties during specific periods when coverage does not need to be offered. For new employees, this relief applies during:

Waiting period (Code 2D):

  • Applies to full-time new hires during the waiting period before coverage begins
  • Maximum 90 days (cannot exceed the first day of the fourth calendar month after hire)
  • Use Line 16 code 2D for these months
  • Line 14 should show 1H (no offer) during the waiting period

Initial measurement period (Code 2B or specific limited non-assessment codes):

  • Applies to variable-hour and seasonal new hires
  • Use code 2B if the employee is not yet determined to be full-time
  • The initial measurement period can last up to 12 months
  • Combined with any administrative period, the total cannot exceed 13 months from hire date plus a fraction of a month for month-start alignment

Important: The limited non-assessment period relief only applies if coverage is ultimately offered to employees determined to be full-time. If you never offer coverage to an employee who becomes full-time, you cannot claim this relief retroactively.

Step-by-Step Examples: Filling Out 1095-C for Common New Hire Scenarios

Example 1: Full-Time New Hire with 90-Day Waiting Period

Consider an employee hired on February 15 for a salaried management position. This is clearly a full-time new hire expected to work well over 30 hours per week. The employer has a 90-day waiting period, so coverage begins on the first of the month following 90 days—in this case, June 1.

1095-C reporting for this new hire:

Month Line 14 Line 15 Line 16 Explanation
January 1H (blank) 2A Not employed
February 1H (blank) 2D Employed mid-month; waiting period relief
March 1H (blank) 2D Waiting period continues
April 1H (blank) 2D Waiting period continues
May 1H (blank) 2D Waiting period continues (90 days ends May 15)
June 1E $150.00 2C Coverage offered and employee enrolled
Jul-Dec 1E $150.00 2C Coverage continues

Example 2: Variable-Hour New Hire Using Initial Measurement Period

Consider an employee hired on March 10 for a retail position where hours vary weekly. The employer cannot determine at hire whether this employee will average 30 hours per week, so they classify the employee as variable-hour and apply a 12-month initial measurement period. The employer's initial measurement period starts on the first of the month following hire (April 1) and runs through March 31 of the following year.

Scenario: After tracking hours, the employee averaged 32 hours per week during the measurement period and must be offered coverage. The employer has a 60-day administrative period, so coverage must be offered by June 1 of the following year.

1095-C reporting for Year 1 (hire year):

Month Line 14 Line 15 Line 16 Explanation
January 1H (blank) 2A Not employed
February 1H (blank) 2A Not employed
March 1H (blank) 2B Partial month; not yet determined full-time
April-December 1H (blank) 2B Initial measurement period; not yet determined full-time

For this variable-hour employee, code 2B is used because the employee has not yet been determined to be full-time. This is the appropriate limited non-assessment period code during the initial measurement period.

Example 3: New Hire Who Declines Coverage

An employee hired on January 2 is clearly full-time. The employer's waiting period ends on April 1, and coverage is offered. However, the employee declines the offered coverage.

1095-C reporting:

Month Line 14 Line 15 Line 16 Explanation
January 1H (blank) 2D Waiting period
February 1H (blank) 2D Waiting period
March 1H (blank) 2D Waiting period
April 1E $175.00 2F Coverage offered; employee declined; W-2 safe harbor
May-December 1E $175.00 2F Coverage continues to be offered; employee not enrolled

When the employee declines coverage, use the appropriate safe harbor code (2F, 2G, or 2H) on Line 16 to demonstrate affordability. Do not use code 2C, which is reserved for employees who actually enroll in coverage.

Example 4: Mid-Year Hire Who Terminates Before Year-End

An employee is hired on July 1 as a full-time employee. After completing the waiting period and enrolling in coverage effective October 1, the employee terminates on November 15.

1095-C reporting:

Month Line 14 Line 15 Line 16 Explanation
January-June 1H (blank) 2A Not employed
July 1H (blank) 2D Waiting period
August 1H (blank) 2D Waiting period
September 1H (blank) 2D Waiting period
October 1E $160.00 2C Coverage offered; enrolled
November 1E $160.00 2C Employed part of month; coverage through termination
December 1H (blank) 2A Not employed

For the termination month (November), report the coverage that was in effect while employed. For December, use code 2A to indicate the employee was not employed. The employee must still receive a 1095-C form because they were full-time for at least one month during the year.

Common Mistakes When Reporting 1095-C for New Hires

Mistake 1: Using Wrong Codes During the Waiting Period

One of the most common errors with 1095-C new hires is using incorrect codes during the waiting period. Many employers mistakenly use code 2B (not full-time) during the waiting period for clearly full-time employees. The correct code is 2D (limited non-assessment period for waiting period). Code 2B should only be used for employees who have not been determined to be full-time, such as during an initial measurement period for variable-hour employees.

Incorrect: Full-time new hire with Line 16 showing 2B during waiting period

Correct: Full-time new hire with Line 16 showing 2D during waiting period

Mistake 2: Failing to Report Part-Year Employees

Employers sometimes fail to issue Form 1095-C to employees who were hired late in the year and terminated before year-end. Under ACA rules, any employee who was full-time for at least one month must receive a 1095-C, regardless of how briefly they were employed. Failing to issue forms to short-term employees can result in penalties for failure to furnish.

Mistake 3: Incorrect Initial Measurement Period Dates

Employers using initial measurement periods for variable-hour 1095-C new hires sometimes make errors in calculating the period dates. Common mistakes include:

  • Starting the measurement period before the hire date
  • Using different measurement period lengths for different employees in the same category
  • Exceeding the maximum combined measurement plus administrative period (13 months plus partial month for alignment)
  • Failing to offer coverage by the start of the stability period when an employee qualifies as full-time

Mistake 4: Misclassifying Employees at Hire

Some employers attempt to classify all new hires as variable-hour to delay offering coverage. The IRS scrutinizes employee classifications, and if an employee's position typically requires full-time hours, they should be classified as full-time from hire. Artificially classifying employees as variable-hour can result in penalty assessments and is not a valid strategy for 1095-C new hires compliance.

Mistake 5: Not Updating Line 16 When Coverage Status Changes

When a new hire transitions from the waiting period to active coverage, Line 16 must change accordingly. A common error is continuing to use code 2D after the waiting period ends. Once coverage is offered and the employee enrolls, use code 2C. If the employee declines, use the applicable safe harbor code (2F, 2G, or 2H).

Penalties for Incorrect New Hire Reporting

Information Return Penalties

Errors on 1095-C new hires forms can trigger IRS information return penalties. These penalties are assessed per form based on how quickly errors are corrected:

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

Beyond information return penalties, incorrect reporting of 1095-C new hires can expose employers to the employer shared responsibility penalty (ESRP). This penalty applies when:

  • Penalty A: The employer fails to offer coverage to at least 95% of full-time employees—approximately $2,900 per full-time employee (minus 30) in 2025
  • Penalty B: The employer offers coverage, but it is unaffordable or lacks minimum value, and an employee receives premium tax credits—approximately $4,350 per affected employee in 2025

Incorrectly reporting new hires—such as failing to offer timely coverage to full-time new hires or misclassifying employees—can trigger these penalties when affected employees obtain subsidized Marketplace coverage.

Letter 226-J: IRS Penalty Assessment Process

The IRS issues Letter 226-J to employers being assessed the ESRP. This letter is based on comparing Form 1095-C data with employee premium tax credit records. If your 1095-C new hires forms contain errors, you may receive a penalty notice for employees who were actually offered coverage but reported incorrectly.

If you receive Letter 226-J, you have the opportunity to respond with corrected information. This is why accurate 1095-C reporting is critical—corrections can prevent or reduce penalty assessments, but only if you can demonstrate accurate coverage was offered.

Deadlines for Furnishing 1095-C to New Hires

Employee Furnishing Deadline

All employees who were full-time for any month during the 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 1095-C new hires who joined the company at any point during the year.

Key considerations for furnishing to new hires:

  • Use the employee's most current address, even if they have since terminated
  • Electronic delivery requires prior consent from the employee
  • The postmark date determines timeliness for mailed forms
  • There is no separate extension for furnishing—only for IRS filing

IRS Filing Deadline

Forms 1095-C must be filed with the IRS by March 31, 2026 (electronic) for tax year 2025. Since virtually all ALEs must file electronically (electronic filing is required for 10+ forms), this is the effective deadline for most employers. The forms are filed with Form 1094-C as the transmittal.

Employers can request a 30-day automatic extension using Form 8809, which would extend the IRS filing deadline to April 30. However, this extension does not extend the employee furnishing deadline.

Frequently Asked Questions About 1095-C for New Hires

What Line 14 code do I use for a new hire during the waiting period?

Use code 1H (no offer of coverage) on Line 14 during the waiting period for full-time new hires. This accurately reflects that coverage was not yet being offered during those months. The waiting period relief is claimed on Line 16 with code 2D, not on Line 14.

When does a new hire's 1095-C reporting begin?

Reporting begins with the first month the employee was employed, even if for only part of the month. For example, if an employee is hired on March 15, their 1095-C includes reporting for March through December (or through their termination month if earlier). Months before the hire date use code 2A on Line 16.

How do I report a variable-hour new hire who becomes full-time mid-year?

During the initial measurement period, use code 1H on Line 14 and code 2B on Line 16. Once the employee is determined to be full-time and coverage is offered, update Line 14 to the appropriate offer code (1A, 1E, etc.) and Line 16 to the applicable safe harbor code or 2C if enrolled.

Do I need to issue 1095-C to a new hire who terminated after two months?

Yes, if the employee was full-time for at least one month. Every employee who meets the full-time threshold for any month during the tax year must receive a Form 1095-C. Short-term new hires who worked full-time hours are included in this requirement.

What if a new hire is offered coverage but the first month is only partial?

Report the full monthly premium on Line 15 for any month coverage was offered, regardless of whether it was a partial month. The IRS does not require proration of premium amounts. If coverage was offered effective for any part of a month, report that month as a month with an offer of coverage.

Can I use the same initial measurement period for all new hires?

You must use consistent initial measurement periods within employee categories (variable-hour, seasonal), but you can have different periods for different categories. You cannot apply the initial measurement period to employees who are clearly full-time at hire. Consistency is required to avoid discriminatory application of the rules.

What code do I use if a new hire is offered coverage but we're waiting for their enrollment decision?

During the open enrollment period when you are waiting for an enrollment decision, use the appropriate offer code on Line 14 (such as 1E) and the applicable safe harbor code on Line 16 (2F, 2G, or 2H). Once the employee makes their decision, update Line 16 to 2C if they enrolled, or continue using the safe harbor code if they declined.

How do I handle a new hire in a state with additional ACA reporting requirements?

States like California, New Jersey, Rhode Island, and District of Columbia have their own ACA reporting mandates. The Form 1095-C for new hires in these states must be filed with both the IRS and the applicable state agency. Filing requirements and deadlines are generally similar to federal requirements.

What happens if I make a mistake on a new hire's 1095-C?

If you discover an error after filing, submit a corrected Form 1095-C as soon as possible. Check the "Corrected" box, enter the correct information, and resubmit. Correcting errors quickly reduces potential penalty amounts. You should also provide a corrected form to the employee.

Do seasonal new hires receive Form 1095-C?

Seasonal new hires receive Form 1095-C only if they were full-time (or determined to be full-time through a measurement period) for at least one month during the year. During the initial measurement period, seasonal employees are treated similarly to variable-hour employees, with their full-time status determined by hours worked during the measurement period.

What if a new hire is rehired later in the same year?

A single Form 1095-C covers all periods of employment during the year. Report all months, using code 2A for months not employed. The treatment of the rehire (new measurement period vs. continuing prior status) depends on the break in service rules and your measurement period policies.

Conclusion: Mastering 1095-C Reporting for New Hires

Accurately completing Form 1095-C for new hires is essential for ACA compliance and avoiding costly penalties. The key to success is understanding the three employee categories (full-time, variable-hour, and seasonal), knowing when waiting period relief and initial measurement period rules apply, and using the correct Line 14 and Line 16 codes for each situation.

Key takeaways for 1095-C new hires:

  • Classify correctly at hire: Determine whether new employees are full-time, variable-hour, or seasonal based on facts at the time of hire
  • Use code 2D for waiting periods: Full-time new hires use code 2D on Line 16 during the maximum 90-day waiting period
  • Use code 2B for measurement periods: Variable-hour and seasonal employees use code 2B during the initial measurement period
  • Report all full-time employees: Any employee who was full-time for even one month must receive a Form 1095-C
  • Update codes when status changes: Change from waiting period codes to offer and safe harbor codes once coverage begins
  • Meet all deadlines: March 3, 2026 for furnishing to employees; March 31, 2026 for IRS filing (tax year 2025)
