Understanding 1095-C Rehired Employee Reporting: A Comprehensive Guide for Employers

Introduction: The Complexity of ACA Reporting for Rehired Employees

One of the most challenging aspects of Affordable Care Act (ACA) compliance is understanding how to properly complete 1095-C rehired employee reporting when former employees return to work. For HR professionals, benefits administrators, and employers managing ACA compliance, rehired employees present unique complexities that require careful attention to IRS regulations and a thorough understanding of the employer shared responsibility provisions.

When an employee leaves your organization and later returns, numerous questions arise about how to handle their Form 1095-C reporting. Should you treat them as a new hire? Do they need to complete a new waiting period? How do you report the months they were not employed? What codes apply to their coverage offer before, during, and after the break in service? The answers depend on several factors, including how long the employee was away, whether they were considered full-time before leaving, and your organization's specific policies.

Getting 1095-C rehired employee reporting wrong can have serious consequences. The IRS imposes penalties of up to $330 per form for incorrect or late filings, with potential penalties reaching millions of dollars for large employers. Beyond financial penalties, inaccurate reporting can trigger Letter 226-J employer shared responsibility payment assessments if the IRS believes you failed to offer adequate coverage. Furthermore, employees may face confusion about their coverage status when reconciling their tax returns.

This comprehensive guide addresses every aspect of 1095-C rehired employee reporting, from fundamental IRS rules about breaks in service to specific line-by-line coding instructions. Whether you handle a few rehires annually or manage a workforce with frequent turnover and seasonal employment, this guide will equip you with the knowledge to handle 1095-C rehired situations confidently and accurately.

Foundational Concepts: IRS Rules for Rehired Employees Under the ACA

Understanding the Break in Service Rules

Before diving into 1095-C rehired reporting specifics, it is essential to understand the IRS rules that govern how employers must treat returning employees. The break in service rules determine whether a rehired employee can be treated as a new hire (potentially subject to a new waiting period and measurement period) or must be treated as a continuing employee with immediate full-time status.

The IRS provides two key thresholds that employers must understand:

The 13-Week Break in Service Rule (Standard Break):

Under the standard break in service rule, an employer may treat a returning employee as a new hire if the employee has a break in service of at least 13 consecutive weeks. During a break in service, the employee has no hours of service with the employer. This 13-week threshold applies to most employees and is the most commonly used rule for determining rehire treatment.

  • If the break is less than 13 weeks: The employee generally cannot be treated as a new hire and must continue their previous measurement/stability period status
  • If the break is 13 weeks or more: The employer may treat the employee as a new hire for ACA purposes, potentially subjecting them to a new initial measurement period and waiting period

The 26-Week Break in Service Rule (Educational Institutions):

For employees of educational institutions, the break in service period is extended to 26 consecutive weeks to accommodate the unique employment patterns at schools and universities.

The Rule of Parity: A Critical Exception

The rule of parity is a critical exception to the 13-week break rule that employers must understand for 1095-C rehired reporting. Under this rule, even if an employee has a break in service of less than 13 weeks, the employer may still treat them as a new hire if the break in service exceeds the employee's prior period of employment.

How the rule of parity works:

  • If an employee worked for 4 weeks before termination and then has a 5-week break, the employer may treat them as a new hire (5 weeks exceeds 4 weeks of prior employment)
  • If an employee worked for 10 weeks before termination and then has a 5-week break, the employer must treat them as a continuing employee (5 weeks does not exceed 10 weeks of prior employment)

The rule of parity is particularly relevant for short-term employees, seasonal workers, and situations where employees leave shortly after starting. It provides flexibility for employers while ensuring that employees with established tenure are not unfairly subjected to new waiting periods.

Full-Time Status Determination for Rehired Employees

A critical question for 1095-C rehired reporting is whether a returning employee is immediately considered full-time or must go through a new measurement period. The answer depends on your organization's measurement method and the circumstances of the rehire.

Look-Back Measurement Method:

For employers using the look-back measurement method, the treatment of rehired employees depends on whether they can be treated as new hires:

  • Cannot be treated as a new hire (break less than 13 weeks or rule of parity applies): The employee retains their previous full-time or non-full-time status based on their prior measurement period determination. If they were full-time during their stability period, they remain full-time upon return.
  • Can be treated as a new hire (break of 13+ weeks or rule of parity satisfied): The employer may start a new initial measurement period. However, if the employee was previously determined to be full-time and is still in their stability period, many employers choose to reinstate full-time status immediately to avoid potential penalty exposure.

Monthly Measurement Method:

For employers using the monthly measurement method, full-time status is determined each month based on whether the employee averages 30 or more hours of service per week. When an employee is rehired:

  • The first month of rehire may be a limited non-assessment period if the employee is treated as a new hire
  • If the employee cannot be treated as a new hire, they must be offered coverage immediately upon return if they work full-time hours

Who Must Receive Form 1095-C When Rehired

Under ACA reporting requirements, Applicable Large Employers (ALEs) must furnish Form 1095-C to every employee who was a full-time employee for any month during the tax year. This includes rehired employees who were full-time during any portion of the year.

Important considerations for 1095-C rehired employees:

  • Single form per employee: A rehired employee receives only one Form 1095-C for the tax year, covering both employment periods and the break in service
  • All 12 months reported: The form reports all 12 months, including months when the employee was not employed (using appropriate codes)
  • Part-time to full-time transitions: If an employee was part-time before termination but returns as full-time (or vice versa), the form reflects both statuses

Comprehensive Analysis: Line 14 Codes for 1095-C Rehired Scenarios

Understanding Line 14 for Rehired Employees

Line 14 of Form 1095-C reports the type of coverage offered to the employee for each month. For 1095-C rehired situations, the key challenge is determining the correct code for three distinct periods: the initial employment period, the break in service, and the period after rehire.

Common Line 14 codes for 1095-C rehired situations:

Code Description When to Use for Rehired Employees
1A Qualifying offer to employee, spouse, and dependents Months when employee was employed and this offer was made
1B Minimum value offered to employee only Months when employee-only coverage was offered during employment
1C Minimum value to employee, MEC to dependents Months when this specific coverage configuration was offered
1E Minimum value offered to employee, spouse, and dependents Most common code when full coverage is offered during employment
1H No offer of coverage Months when the employee was not employed (break in service)

Line 14 Coding During the Break in Service

For months when a rehired employee was not employed (the break in service period), the correct Line 14 code is typically 1H (No offer of coverage). This is because you cannot offer health coverage to someone who is not your employee.

Important considerations:

  • No offer during break: Use code 1H for all months during the break in service
  • COBRA is not an employer offer: If the former employee elected COBRA continuation coverage during their break, this is not reported as an employer offer on Line 14. COBRA is separate from the employer's ACA obligation.
  • Partial months: If termination or rehire occurs mid-month, use the code that applies for the majority of the month, or the code for the end of the month if the employee is employed at month-end

Line 14 Coding for the Rehire Period

When the employee returns to work, the Line 14 code depends on whether they are immediately offered coverage or must complete a waiting period:

Scenario 1: Immediate offer of coverage upon rehire

  • If the employee cannot be treated as a new hire (break less than 13 weeks), coverage must generally be offered immediately
  • Use the appropriate offer code (1A, 1E, etc.) starting with the month of rehire

Scenario 2: New waiting period applies

  • If the employee can be treated as a new hire and your plan has a waiting period, coverage may not be offered immediately
  • Use code 1H during any legitimate waiting period months
  • Use the appropriate offer code once coverage is offered

Special Considerations for Line 14

When completing 1095-C rehired forms, pay attention to these special considerations:

  • Seasonal employees: Employees who work seasonal schedules may have predictable breaks that do not trigger new hire treatment if the total break is less than 13 weeks
  • Multiple rehires in one year: If an employee is terminated and rehired multiple times within the same tax year, apply the break in service rules to each separation and report accordingly
  • Changes in coverage offers: If your health plan options changed between the employee's original employment and rehire, report the offers that were actually available during each period

Line 15 Reporting for Rehired Employees

Employee Share of Premium for Rehired Employees

Line 15 reports the employee's monthly share of the lowest-cost self-only minimum value coverage offered. For 1095-C rehired reporting, this line requires careful attention to the specific circumstances of each period.

Key points for Line 15 during rehire situations:

  • During employment periods: Report the actual employee premium share for the lowest-cost self-only coverage offered
  • During break in service: Leave Line 15 blank for months coded 1H on Line 14 (no offer of coverage)
  • Premium changes: If premium amounts changed between the original employment and rehire (due to annual enrollment, plan changes, etc.), report the applicable amount for each period
  • Code 1A exception: If Line 14 is coded 1A (qualifying offer), Line 15 may be left blank since the qualifying offer inherently meets affordability standards

Premium Amount Scenarios for Rehired Employees

Example 1: Maria worked January through March, was terminated, and was rehired in August. Her premium contribution was $200 throughout. Line 15 shows $200.00 for months employed and is blank for April through July.

Example 2: James worked January through April ($175 premium), was terminated, and was rehired in September after annual enrollment raised rates to $225. Line 15 shows $175.00 for January-April and $225.00 for September-December. Line 15 is blank for May through August.

Line 16 Codes for 1095-C Rehired Situations

Understanding Line 16 for Rehired Employees

Line 16 of Form 1095-C reports applicable safe harbors and other relief provisions. For 1095-C rehired situations, selecting the correct Line 16 code is crucial for demonstrating compliance and avoiding employer shared responsibility penalties.

Most common Line 16 codes for 1095-C rehired scenarios:

Code Description When to Use for Rehired Employees
2A Employee not employed during the month Months during the break in service when the employee was not employed
2B Not a full-time employee Months when employee worked but was not full-time
2C Employee enrolled in coverage Months when employee was enrolled in minimum value coverage
2D Employee in limited non-assessment period Months during a valid waiting period or initial measurement period after rehire (if treated as new hire)
2F W-2 safe harbor Months when coverage was affordable based on W-2 wages
2G Federal poverty line safe harbor Months when coverage was affordable based on FPL
2H Rate of pay safe harbor Months when coverage was affordable based on rate of pay

Line 16 Coding During the Break in Service

For months when the rehired employee was not employed, the correct Line 16 code is 2A (Employee not employed during the month). This code indicates that no employer shared responsibility penalty can apply because there was no employment relationship.

Critical distinction from other scenarios:

  • Rehired employees use 2A: For true breaks in employment where the employee was terminated and later rehired
  • FMLA employees do NOT use 2A: Employees on FMLA leave remain employed and should not use code 2A
  • Terminated employees: If an employee is terminated and not rehired, use 2A for months after termination

Line 16 Coding for the Rehire Period

When the employee returns to work, the Line 16 code depends on several factors:

If treated as a new hire with a waiting period:

  • Use code 2D for months during the limited non-assessment period (waiting period or initial measurement period)
  • The limited non-assessment period is capped at the later of 90 days or the first day of the month following the initial measurement period

If the employee enrolls in coverage:

  • Use code 2C for months when the employee is enrolled in minimum value coverage
  • This is the strongest protection against penalties

If the employee declines coverage:

  • Use the applicable safe harbor code (2F, 2G, or 2H) if the coverage was affordable
  • The rate of pay safe harbor (2H) is often useful for rehired employees because it uses their current rate of pay

Combining Codes Throughout the Year

A typical 1095-C rehired employee may have multiple Line 16 codes: 2C for months enrolled, 2A for months not employed, and 2D for legitimate waiting periods after rehire.

Limited Non-Assessment Periods for Rehired Employees

When New Waiting Periods Apply

One of the most important aspects of 1095-C rehired reporting is understanding when an employer may apply a new waiting period after rehire. This depends on whether the employee can be treated as a new hire under the break in service rules.

New waiting period permitted when:

  • The employee has a break in service of at least 13 consecutive weeks (26 weeks for educational institutions)
  • The rule of parity is satisfied (break exceeds prior employment period)
  • The employee was not in a stability period as a full-time employee at the time of termination

New waiting period NOT permitted when:

  • The break in service is less than 13 weeks and does not satisfy the rule of parity
  • The employee was in a stability period as a full-time employee and remains in that period upon return

Maximum Waiting Period Duration

Under ACA regulations, the maximum waiting period is 90 days. Coverage must be offered no later than the first day of the month following 90 days. Use code 2D on Line 16 for months during the legitimate waiting period.

Initial Measurement Period for Rehired Employees

For employers using the look-back method, rehired employees treated as new hires may be subject to a new initial measurement period (up to 12 months) plus an administrative period (up to 90 days). Combined, this cannot extend beyond 13 months and a fraction from the start date. Use code 2D on Line 16 during this limited non-assessment period.

Part III Reporting for Self-Insured Plans

When to Complete Part III for Rehired Employees

Part III of Form 1095-C applies only to employers with self-insured health plans. For 1095-C rehired situations with self-insured coverage, Part III documents the months during which individuals were actually enrolled in coverage.

Part III completion for rehired employee situations:

  • Initial employment period: Check the boxes for each month the employee was enrolled before termination
  • Break in service: Do not check boxes for months when the employee was not enrolled (typically aligns with termination)
  • COBRA during break: If the employee elected COBRA during the break, this may be reported on Part III if the employer sponsors a self-insured plan providing the COBRA coverage
  • After rehire: Check the boxes for each month the employee was enrolled after returning

Dependent Coverage Considerations

For Part III, list each covered dependent with their SSN or date of birth and check the months of enrollment. Dependents may have different coverage months than the employee (e.g., if dependents lost coverage at termination but the employee had COBRA).

Step-by-Step Guidance: Completing 1095-C for Rehired Employees

Scenario 1: Short Break in Service (Less Than 13 Weeks)

Jennifer is a full-time employee who was terminated on March 15 and rehired on May 20 (approximately 9-week break). She was in a stability period as a full-time employee when she left. She enrolled in coverage upon her return.

Step-by-step 1095-C completion:

Part I: Complete employee and employer information as normal.

Part II, Line 14:

Month Code Explanation
January - March 1E Full coverage offered during initial employment
April - May 1H No offer during break (not employed)
June - December 1E Full coverage offered immediately upon rehire (cannot be treated as new hire)

Part II, Line 15:

  • January - March: $200.00 (her premium share)
  • April - May: Blank (no offer)
  • June - December: $200.00

Part II, Line 16:

Month Code Explanation
January - March 2C Enrolled in coverage
April - May 2A Not employed during these months
June - December 2C Enrolled in coverage after rehire

Part III: Check January, February, March, June, July, August, September, October, November, and December (all months of actual enrollment).

Scenario 2: Long Break in Service (13+ Weeks) with New Waiting Period

Robert is a full-time employee who was terminated on February 28 and rehired on August 1 (5-month break). Because his break exceeds 13 weeks, he can be treated as a new hire. The employer applies a 60-day waiting period. He enrolls in coverage effective October 1.

Step-by-step 1095-C completion:

Part II, Line 14:

Month Code Explanation
January - February 1E Full coverage offered during initial employment
March - July 1H No offer during break (not employed)
August - September 1H No offer during waiting period
October - December 1E Full coverage offered after waiting period

Part II, Line 16:

Month Code Explanation
January - February 2C Enrolled in coverage
March - July 2A Not employed during these months
August - September 2D Limited non-assessment period (waiting period)
October - December 2C Enrolled in coverage

Scenario 3: Rule of Parity Application

Lisa started work on January 15 and was terminated on February 10 (approximately 4 weeks of employment). She was rehired on March 25 (approximately 6-week break). Although the break is less than 13 weeks, it exceeds her prior employment period, so the rule of parity allows treating her as a new hire. Report coverage offered during initial employment, use 2A for months not employed, and use 2D for any valid waiting period after rehire.

Scenario 4: Multiple Rehires in One Year

David is a seasonal employee who works January through March, is terminated, rehired June through August, terminated again, and rehired October through December. Each break is less than 13 weeks. Use 2C for months enrolled, 2A for months not employed. Coverage must be offered immediately upon each rehire since each break is less than 13 weeks.

Common Mistakes and How to Avoid Them

Mistake 1: Applying New Waiting Periods When Not Permitted

If the break is less than 13 weeks and the rule of parity is not satisfied, coverage must be offered immediately. Always calculate the exact break length before determining whether a new waiting period applies.

Mistake 2: Using Code 2A Incorrectly

Code 2A should only be used when the employee was truly not employed. Do not use 2A for employees on leave who remain employed.

Mistake 3: Incorrect Part III Reporting for COBRA

Include COBRA on Part III only if your self-insured plan provided the coverage. Fully insured COBRA is reported by the carrier on Form 1095-B.

Mistake 4: Forgetting to Update Employee Address

Verify and update the employee's current address upon rehire before generating the Form 1095-C.

Mistake 5: Misapplying the Rule of Parity

The rule of parity compares break duration to prior employment period, not to 13 weeks. Both conditions can independently allow new hire treatment.

Deadlines and Penalties for 1095-C Rehired Reporting

Filing and Furnishing Deadlines

For tax year 2025, 1095-C rehired forms must be furnished to employees by March 3, 2026, and filed electronically with the IRS by March 31, 2026 (paper filing by February 28, 2026 for fewer than 10 forms). Electronic filing is required for 10+ forms. Ensure you have rehired employees' current addresses before the deadline.

Penalties for Incorrect Reporting

Inaccurate 1095-C rehired reporting can result in significant penalties:

  • $60 per form if corrected within 30 days of the required filing date
  • $130 per form if corrected after 30 days but by August 1
  • $330 per form if not corrected by August 1
  • $660 per form (no maximum) for intentional disregard

Additionally, incorrect 1095-C rehired coding could lead to erroneous employer shared responsibility penalty assessments through Letter 226-J.

How to Correct 1095-C Rehired Errors

If you discover errors, file corrected forms promptly. Check the "CORRECTED" box, enter all information correctly, furnish a copy to the employee, and file through the IRS AIR system.

Frequently Asked Questions About 1095-C Rehired Reporting

How long of a break triggers new hire treatment for ACA purposes?

A break in service of at least 13 consecutive weeks (26 weeks for educational institutions) allows the employer to treat the returning employee as a new hire. Alternatively, the rule of parity allows new hire treatment if the break exceeds the prior employment period, even if less than 13 weeks.

Do rehired employees need a new waiting period for health coverage?

It depends on whether they can be treated as new hires. If the break in service meets the 13-week threshold or satisfies the rule of parity, a new waiting period may be applied. If not, coverage must generally be offered immediately upon return.

What code do I use on Line 16 for months the employee was not employed?

Use code 2A (Employee not employed during the month) for any month during the break in service when the employee was not your employee.

Does COBRA coverage during the break affect 1095-C reporting?

COBRA coverage is not reported as an employer offer on Line 14. If the COBRA coverage was provided through your self-insured plan, it may be reported on Part III. Fully insured COBRA coverage is reported by the carrier on Form 1095-B.

How do I report an employee rehired multiple times in one year?

Apply the break in service rules to each separation. If any break is 13+ weeks or satisfies the rule of parity, that rehire may be treated as a new hire. Each period is coded separately on the monthly lines of Form 1095-C.

What if a rehired employee was part-time before but is full-time after?

Report the actual status for each period. Line 16 might show 2B (not full-time) for months during the initial part-time employment, 2A for the break, and then the appropriate code for the full-time period after rehire.

Should I apply the rule of parity to seasonal employees?

The rule of parity applies to all employees. For seasonal employees with short initial work periods followed by breaks that exceed their employment period, the rule allows new hire treatment even if the break is less than 13 weeks.

Can I use a safe harbor code for the month an employee is rehired?

Yes, if the employee is offered affordable coverage upon rehire and declines, you can use the applicable safe harbor code (2F, 2G, or 2H). If the employee enrolls, use code 2C.

What happens if I incorrectly treat a rehired employee as a new hire?

If you apply a new waiting period when not permitted, you may have failed to offer coverage as required under the employer mandate. This could result in employer shared responsibility penalties if the employee obtained subsidized coverage through the Marketplace.

Do I need to issue two separate 1095-C forms for a rehired employee?

No. Issue a single Form 1095-C covering all 12 months of the tax year. The form reports both employment periods and the break in service using appropriate codes for each month.

How do state ACA requirements affect rehired employee reporting?

States with individual mandate reporting requirements (California, New Jersey, D.C., Rhode Island, Massachusetts) have their own filing obligations. The same information reported to the IRS is generally reported to these states as well.

What if the employee's address changed during the break?

Use the employee's current address when furnishing the Form 1095-C. Update your records upon rehire to ensure accurate delivery.
