Recently, the Internal Revenue Service (IRS) released Rev. Proc. 2023-29, which sets the Affordable Care Act (ACA) affordability percentage to 8.39% for plan years beginning in 2024. The 2024 rate marks another notable decrease (down from 9.12% for 2023) and is the lowest affordability threshold since the inception of the ACA. As such, Applicable Large Employers (ALEs) may need to lower employee contributions towards medical coverage to meet the affordability requirement and avoid potential penalties in 2024.
As a reminder, the ACA requires ALEs to offer affordable minimum value coverage to their full-time employees and dependents or face a potential penalty. Based on the 2024 affordability rate, ALEs (with plan years beginning January 1, 2024, through June 1, 2024) will automatically meet the affordability requirement if they offer at least one plan that costs employees no more than $101.93 per month for self-only coverage under the Federal Poverty Level (FPL) safe harbor. See below for distinctions for plan years beginning on or after July 1, 2024, as well as a further discussion on alternative ways employers can meet the affordability requirement.
Compliance Snapshot
- For plan years beginning in 2024, ALEs must offer at least one plan where the cost of self-only coverage does not exceed 8.39% of the employee’s household income.
- ALEs with plan years beginning January through June 2024 that offer at least one plan that costs employees no more than $101.93 per month for self-only coverage will meet 2024 affordability under the FPL safe harbor.*
- ALEs who use an affordability safe harbor other than the FPL (i.e., the W-2 or Rate of Pay) may rely on the 8.39% rate.
*Note that employers are permitted to use the federal poverty guidelines in effect six months prior to the beginning of the plan year to calculate affordability under the FPL safe harbor. The 2024 federal poverty amount will be released in early 2024 and employers with plan years beginning after its release may use that number to calculate affordability (noting that plan years beginning July through December 2024 are required to use the 2024 federal poverty amount to calculate affordability), explained further below and in our blog, ACA Affordability for Non-Calendar Year Plans.
Frequently Asked Questions
Which employers are considered Applicable Large Employers (ALEs) under the ACA?
ALEs are employers with 50 or more full-time and full-time equivalent employees, on average, in the prior calendar year. Non-ALEs are not subject to the ACA employer mandate and are not subject to the “affordability” requirement. Companies with a common owner (part of a controlled group) or that are otherwise related under section 414 of the Internal Revenue Code are generally combined and treated as a single employer for determining ALE status. For additional information on how to determine ALE status, see this IRS webpage.
What type of coverage must an ALE offer under the ACA?
Under the ACA employer mandate (also known as the “pay or play mandate”), ALEs must offer affordable, minimum value coverage to full-time employees and their dependents, or potentially face a penalty.
What is minimum value coverage?
A group health plan meets the minimum value coverage requirement if it pays at least 60 percent of the total allowed cost of benefits that are expected to be incurred by the plan and substantially covers in-patient hospitalization or physician services.
How can employers determine whether their coverage is “affordable” under ACA?
For plan years starting in 2024, ALEs must offer at least one plan that costs employees no more than 8.39% of their household income. ALEs can utilize any one of the three following “safe harbors” to determine whether they meet the 2024 affordability requirement:
- Federal Poverty Level (FPL): Coverage will be affordable if the cost to employees for self-only coverage on the lowest-cost plan offered is no more than 8.39% of the federal poverty level (which is determined annually). For 2024, employers with plan years beginning January through June 2024 will meet the FPL safe harbor if they offer their full-time employees at least one plan that costs no more than $101.93 ($127.31 for Alaska, and $117.25 for Hawaii) for self-only coverage.
- Rate of Pay: This safe harbor will be met if the cost to employees for self-only coverage does not exceed 8.39% of their monthly salary (or hourly rate multiplied by 130).
- W-2: This safe harbor will be met if the cost to an employee for self-only coverage does not exceed 8.39% of that employee’s annual wages, as outlined on their W-2 at the end of the year. This approach is generally not recommended, as employers will not know the exact wages reported on employees’ W-2s until the end of 2024. As such, it is a bit less predictable than the other two methods.
For more on the affordability safe harbors, see the IRS Q&A on Affordability.
What is the simplest method for employers to meet affordability?
The easiest method for meeting affordability is the FPL safe harbor because it allows employers to determine a single amount that is considered affordable for all employees. Further, it provides employers with a streamlined approach for completing their ACA reporting.
Under the FPL safe harbor, an employer must offer at least one plan with self-only coverage that costs employees no more than the FPL safe harbor amount. The 2024 FPL safe harbor amount is calculated based on the following formula:
Monthly 2024 Safe Harbor Amount = [8.39% x Federal Poverty Level (FPL)] / 12
Although the 2024 FPL is not released until early 2024, ALEs can rely on federal poverty guidelines in effect six months prior to the beginning of the plan year (i.e., the 2023 FPL guidelines) to calculate the safe harbor amounts for 2024, as mentioned above. Based on the 2023 FPL guidelines, ALEs with plan years beginning January through June 2024 will offer affordable coverage if they offer at least one plan that costs employees no more than $101.93 per month.
What about non-calendar year plans?
Employers with plan years beginning after the 2024 FPL guidelines are released (e.g., February through June 2024) may use the 2024 FPL guidelines to calculate affordability. Importantly, plan years beginning July through December 2024 are required to use the 2024 FPL guidelines to calculate affordability.
How can employers meet affordability?
If an ALE determines that they are not meeting affordability under one of the three safe harbors outlined above, they must increase the employer contribution toward self-only medical coverage (to lower the employee share of the premiums) so that the employee share of at least one medical plan offered to full-time employees is deemed affordable.
It is important for ALEs to be aware that the “affordable” plan must be offered to all of their full-time employees (those working an average of at least 30 or more hours per week). ALEs that offer different medical plans to different groups of full-time employees should be especially vigilant to ensure an affordable plan is offered to each group of full-time employees.
What are the penalties if ALEs do not offer affordable coverage?
An ALE who does not comply with the employer mandate and has at least one full-time employee that receives a premium subsidy for enrolling in coverage through the Marketplace Exchange may receive one of two potential penalties, as outlined below:
- Penalty A: If an ALE fails to offer minimum essential coverage to at least 95% of their full-time employees in any calendar month, they may be subject to an “A” penalty. The A penalty is triggered if at least one full-time employee enrolls in coverage through the Exchange and receives a premium subsidy for coverage. The A penalty is determined by multiplying the penalty amount (which changes annually) by all full-time employees (reduced by the first 30 employees), whether or not those employees enroll in the Exchange.
- Penalty B: If an ALE offers coverage to more than 95% of their full-time employees but fails to offer affordable, minimum value coverage to all full-time employees, they may be subject to a “B” penalty. The B penalty is triggered if a full-time employee is not offered affordable minimum value coverage (i.e., they are offered unaffordable coverage or coverage that does not meet minimum value) and they receive a premium subsidy for enrolling onto the Exchange for any calendar month. The B penalty is determined by multiplying the penalty amount (which changes annually) by the number of employees who receive subsidized coverage on the Exchange (it is not based on the total number of full-time employees like the “A” penalty).
The 2024 penalties, as compared to the 2023 penalties, are as follows:
| 2024 | 2023 | |
| Penalty A | $247.50/month ($2,970 annualized) | $240/month ($2,880 annualized) |
| Penalty B | $371.67/month ($4,460 annualized) | $360/month ($4,320 annualized) |
How does the IRS determine whether an employer owes a penalty?
To determine whether an employer owes a penalty, the IRS compares the employer’s ACA reporting with the list of employees who received a government subsidy to purchase coverage through the Exchange. Penalties are triggered if an employer fails to offer a full-time employee proper coverage and that employee receives a government subsidy for Exchange coverage.
If an employer is subject to a penalty, the IRS will send the employer a 226J Notice letter outlining how much the IRS believes the employer owes.
Employer Next Steps
- ALEs should be aware of the 2024 affordability rates when determining their group health plan offerings and contribution strategies for the upcoming 2024 plan year.
- ALEs should ensure their group health plan is affordable under one of the affordability safe harbors (FPL, Rate of Pay, or W-2).
