FTE (Full-Time Equivalent): What It Means for Employers

What it means in practice

FTE expresses a workforce in full-time units instead of heads; two half-time employees can equal one FTE. Two federal tax rules use it, each defined differently: the Affordable Care Act employer shared responsibility provisions (Internal Revenue Code section 4980H) and the small business health care tax credit (section 45R). There is no single federal FTE definition for wage and hour law: DOL says the Fair Labor Standards Act "does not define full-time employment or part-time employment" and that this "is a matter generally to be determined by the employer."

Why FTEs matter: ALE status. Two ACA provisions apply only to applicable large employers: employer shared responsibility and information reporting on offers of coverage. ALE status is set each calendar year from the prior year's average workforce (IRS, Determining if an employer is an ALE). The statute says FTEs are counted "solely for purposes of determining whether an employer is an applicable large employer" (26 U.S.C. 4980H(c)(2)(E)).

Key definitions. An employee is a common-law employee; sole proprietors, partners, 2-percent S corporation shareholders, leased employees under section 414(n), and qualified real estate agents and direct sellers are not employees for this purpose (26 CFR 54.4980H-1(a)(15); IRS ESRP Q&A 19). A full-time employee for a month averages at least 30 hours of service per week, with 130 hours in the month as the monthly equivalent. An FTE is "a combination of employees, each of whom individually is not treated as a full-time employee," counted together as the equivalent of a full-time employee solely for the ALE test (54.4980H-1(a)(22)).

What counts as an hour of service. An hour of service is each hour an employee is paid, or entitled to payment, for performing duties, plus each paid hour with no duties because of vacation, holiday, illness, incapacity, layoff, jury duty, military duty or leave of absence (54.4980H-1(a)(24)). So paid leave counts even when no duties are performed; see also hours worked. Bona fide volunteer, Federal Work-Study and foreign-source hours are excluded. Hourly employees' hours come from actual records. For non-hourly employees an employer may use actual hours, a days-worked equivalency (8 hours for each day with at least one hour of service) or a weeks-worked equivalency (40 hours for each such week), but not an equivalency that substantially understates hours, such as a days-worked count for someone working three 10-hour days (26 CFR 54.4980H-3(b)).

How the ALE calculation works, step by step. IRS Publication 5208 and 26 CFR 54.4980H-2 set out the method. (1) For each month of the prior calendar year, count the full-time employees (30 hours a week or 130 hours in the month). (2) For each month, add the hours of service of every employee who was not full-time, counting no more than 120 hours for any one person, and divide by 120 to get that month's FTEs. (3) Add the 12 monthly full-time counts and the 12 monthly FTE counts, then divide by 12. (4) If the result is not a whole number, round down to the next lowest whole number. A result of 50 or more makes the employer an ALE for the current year unless the seasonal worker exception applies. The monthly measurement method is used for this test; the look-back measurement method can be used only for computing payment liability, not for deciding ALE status (54.4980H-3(a)).

Example 1: a workforce just under the line. A Remindax illustration with assumed numbers: every month of last year a company had 38 employees with at least 130 hours of service, 14 part-time employees with 80 hours each, and 2 employees with 125 hours each. The two 125-hour employees are not full-time, so they go into the FTE pool, but only 120 hours each can be counted. Monthly FTE hours are 1,120 (14 x 80) plus 240 (2 x 120), or 1,360; divided by 120 that is 11.33 FTEs. The yearly sum is 456 full-time (38 x 12) plus 135.96 FTEs (11.33 x 12), or 591.96, and 591.96 / 12 = 49.33, which rounds down to 49. The company is not an ALE this year. Had it employed one more full-time employee every month, the average would be 50.33, rounding to 50, and it would be one.

IRS examples. The IRS ALE page shows Company X with 40 full-time and 15 part-time employees at 60 hours a month: 7.5 FTEs (900 / 120), an average of 47.5, rounded to 47, so not an ALE despite 55 employees. Company Y, with 20 such part-timers, has 10 FTEs and averages exactly 50, so it is an ALE.

The seasonal worker exception. An employer is not treated as having more than 50 full-time employees (including FTEs) if its workforce exceeded 50 for 120 days or fewer during the prior calendar year and the employees above 50 during that period were seasonal workers (26 U.S.C. 4980H(c)(2)(B)). Four calendar months may be treated as 120 days, and they need not be consecutive (54.4980H-2(b)(2)). A seasonal worker performs labor or services on a seasonal basis, including retail workers employed exclusively during holiday seasons, and employers may use a reasonable, good faith interpretation of the term (54.4980H-1(a)(39)). A "seasonal employee" is a different look-back method term (IRS ESRP Q&A 27).

Example 2: holiday staff. Assumed numbers: a retailer had 45 non-seasonal full-time employees all year and added 20 full-time holiday workers for October through December. Its average is (45 x 9 + 65 x 3) / 12 = 50, but the workforce topped 50 for only three months and the 15 employees above 50 were seasonal workers, so the exception applies and it is not an ALE.

Who else counts, and who does not. Companies under common ownership or otherwise related under section 414(b), (c), (m) or (o) are combined to test ALE status, and each member of the group is then part of an ALE even if it is small on its own; any payment is still figured separately for each member (IRS ESRP Q&A 11 and 12). Employees with other coverage such as Medicare, Medicaid or a spouse's plan are counted, but employees with TRICARE or VA health coverage are not counted for that month (Q&A 6 and 15; 4980H(c)(2)(F)). Work performed abroad generally is not counted (Q&A 17). Workers who are not common-law employees, such as an independent contractor, fall outside the employee definition above. A business that did not exist on any business day of the prior year is an ALE if it reasonably expects to employ, and actually employs, an average of at least 50 full-time employees, including FTEs, on business days in the current year (54.4980H-2(b)(3)).

What ALE status leads to. An ALE member must either offer affordable, minimum value coverage to its full-time employees and their dependents or potentially owe an employer shared responsibility payment (IRS ESRP page). One payment can apply if it does not offer coverage to at least 95 percent of full-time employees and at least one full-time employee receives the premium tax credit; the other can apply for each full-time employee who receives the credit even when the 95 percent offer was made. The statute's base amounts are $2,000 and $3,000 a year, indexed for inflation (check the IRS for current figures). An ALE need not offer coverage to part-time employees, and a part-time employee's premium tax credit cannot trigger a payment (Q&A 21). The IRS says an employer "should not make a payment without first being contacted by the IRS," proposes payments by Letter 226J, and the statute gives an ALE at least 90 days to respond to the first letter (4980H(d)(4)). ALEs also report coverage offers on Forms 1094-C and 1095-C (Pub 5208).

The small business health care tax credit uses a different FTE. Under section 45R and the Instructions for Form 8941 (2025), FTEs are total annual hours of service for which wages were paid, counting no more than 2,080 hours per employee, divided by 2,080 and rounded down to a whole number (or 1 if less than one). The IRS notes this "is different from other provisions of the Affordable Care Act that count 30 hours per week." To be an eligible small employer for 2025, an employer must pay premiums under a qualifying arrangement, have fewer than 25 FTEs, and pay average annual wages of less than $67,000 per FTE; the credit is reduced above 10 FTEs or above $33,000 in average wages. Owners (sole proprietors, partners, more-than-2% S corporation shareholders, more-than-5% owners) and their family members are excluded, and seasonal workers who work 120 or fewer days are left out of FTEs and average wages. Wages mean wages subject to FICA withholding, without the wage base limit. The IRS says an employer with 48 half-time employees has 24 FTEs and can claim the credit.

Example 3: Form 8941 FTEs. Assumed numbers: a shop has 8 full-time employees, one of whom worked 2,300 hours, and 6 part-time employees at 1,040 hours each; the owner, a sole proprietor, also works full-time. The owner is excluded and the 2,300-hour employee counts as 2,080. Hours are 16,640 (8 x 2,080) plus 6,240 (6 x 1,040), or 22,880, and 22,880 / 2,080 = 11 FTEs: under 25, but above the 10 FTEs where the credit starts to shrink.

FMLA counts heads, not FTEs. The FMLA covers a private employer that maintained 50 or more employees on the payroll during 20 or more calendar workweeks, not necessarily consecutive, in the current or preceding calendar year (29 CFR 825.105(e)). Anyone on the payroll counts, paid that week or not, and part-time employees count the same as full-time employees (825.105(b) and (c)). Assumed numbers: an employer with 30 full-time employees and 25 part-time employees at 40 hours of service a month has 55 people on the payroll, so it meets the FMLA count if that lasts 20 workweeks, but has only 8.33 ACA FTEs a month (1,000 / 120), an average of 38, so it is not an ALE. Individual eligibility separately requires 1,250 hours of service in the prior 12 months (DOL Fact Sheet #28).

FTE in budgets. Outside these tax rules, FTE is a planning measure. The federal government's own budget guidance, OMB Circular A-11 (2025), section 85, defines FTE employment as regular straight-time hours worked, excluding overtime and holiday hours worked but counting approved leave, divided by the compensable hours in the fiscal year: 2,088 for fiscal year 2026 under its regular method, or 2,080 under its 26-pay-period method. Private employers set their own definitions, built from payroll hours.

Recordkeeping. The FTE math depends on hours records. The FLSA requires employers to record hours worked each workday and each workweek for employees covered by its minimum wage and overtime rules (29 CFR 516.2(a)(7)) and to keep payroll records for at least 3 years (29 CFR 516.5).

Where states differ. The ALE and Form 8941 tests are federal tax rules. State laws can use their own employee-count tests; check your state labor department through DOL's state labor offices directory. One federal example of state-specific treatment: employers in Hawaii cannot claim the Form 8941 credit for plan years beginning after 2016 because of a state innovation waiver (Instructions for Form 8941).

Questions employers ask. Does hiring part-timers this year make us an ALE now? No. New hires count toward next year's determination (IRS ESRP Q&A 8). Is an FTE the same as a full-time employee? No; FTEs only help decide ALE status (Q&A 21). Do we round each month? Monthly FTEs keep fractions and may be rounded to the nearest hundredth; only the yearly average is rounded down (54.4980H-2).
