The Internal Revenue Service (IRS) has officially released updated affordability percentages for the 2027 plan year, marking a significant shift in the regulatory landscape for Applicable Large Employers (ALEs). Under the newly issued Revenue Procedure 2026-26, the health coverage affordability threshold will rise to 10.22% of an employee’s household income. This adjustment follows a period of incremental increases and represents a notable departure from the 9.96% rate utilized during the 2026 calendar year. For organizations with 50 or more full-time equivalent employees (FTEs), this change necessitates a comprehensive review of employer-sponsored health plans to ensure continued compliance with the Affordable Care Act’s (ACA) employer shared responsibility provisions.
The affordability requirement is a cornerstone of the ACA, designed to ensure that full-time employees are not overburdened by the cost of employer-sponsored health insurance. If an employer’s least expensive plan—which must also meet minimum value and provide minimum essential coverage (MEC)—exceeds this federal percentage, the employer may be subject to substantial penalties. The 2027 increase to 10.22% provides employers with slightly more latitude in determining employee premium contributions, as it allows the employee’s share of the premium to constitute a larger portion of their household income compared to previous years.
The Regulatory Framework of ACA Affordability
To understand the implications of the 2027 update, it is essential to examine the mechanism of the ACA’s employer mandate. The law distinguishes between small businesses and ALEs, the latter of which are defined as organizations with 50 or more FTEs. These larger entities are legally required to offer "affordable" coverage that meets "minimum value" standards to at least 95% of their full-time workforce.
Because employers rarely have access to an employee’s total household income data—which may include income from spouses, investments, or secondary employment—the IRS provides three "safe harbors." These benchmarks allow employers to calculate affordability based on data readily available in their payroll systems. The 10.22% threshold for 2027 will be applied to these safe harbors: the Federal Poverty Level (FPL) safe harbor, the W-2 wages safe harbor, and the rate-of-pay safe harbor.
The FPL safe harbor is often favored by employers with high turnover or fluctuating hours because it provides a single, predictable dollar amount. For the 2027 plan year, the maximum monthly premium an employee can be required to pay under the FPL safe harbor for a self-only plan is approximately $135.93 for the mainland United States. This is an increase from the $129.90 limit seen in 2026, reflecting the higher percentage allowed by the IRS.
Chronology of Affordability Adjustments (2020–2027)
The annual adjustment of the affordability percentage is tied to the growth of health insurance premiums relative to the growth in the consumer price index. This has led to a fluctuating trend over the last several years, impacting how HR departments budget for benefits.
- 2020–2022: The rates remained relatively high, peaking at 9.83% in 2021 before a slight dip to 9.61% in 2022.
- 2023–2024: A period of significant reduction occurred, with the rate dropping to 9.12% in 2023 and reaching a historic low of 8.39% in 2024. This forced many employers to increase their premium subsidies to remain compliant.
- 2025–2027: The trend reversed. The rate climbed to 9.02% in 2025, rose to 9.96% in 2026, and has now reached 10.22% for 2027.
This upward trajectory since 2024 suggests a regulatory environment that is adjusting for the rising costs of healthcare delivery. For 2027, the increase to 10.22% means that employers can theoretically reduce their contribution to employee premiums without losing their "affordable" status, provided the employee’s contribution does not exceed the new cap.
Impact on Individual Coverage HRAs (ICHRA)
The 2027 update also has direct consequences for employers utilizing Individual Coverage Health Reimbursement Arrangements (ICHRAs), often referred to as Choice Arrangements. An ICHRA allows employers to reimburse employees for individual health insurance premiums rather than providing a traditional group plan. However, for an ALE, the ICHRA must still meet the affordability test.
To determine ICHRA affordability, employers must use the lowest-cost silver plan available on the local exchange in the employee’s primary worksite or residence. The formula for 2027 is as follows:
- Multiply the employee’s household income (or safe harbor equivalent) by 0.1022.
- Divide that number by 12 to find the monthly maximum.
- Subtract this monthly maximum from the premium of the lowest-cost silver plan in the area.
The resulting figure is the minimum monthly allowance the employer must provide through the ICHRA to satisfy the mandate. For example, if an employee earns $45,000 annually, their 10.22% threshold is $4,599 per year, or $383.25 per month. If the local silver plan costs $550, the employer must provide an ICHRA allowance of at least $166.75 per month.
Compliance and the "Play or Pay" Dilemma
As the 2027 plan year approaches, ALEs face a strategic decision often termed "Play or Pay." With the IRS increasing the affordability threshold, employers have a clearer window to adjust their benefits packages, but the stakes for non-compliance remain high.
The "Play" Option:
Employers choose to "play" by offering a plan that meets the 10.22% affordability threshold. By adjusting contributions to ensure the lowest-cost, self-only plan stays within this limit, the organization avoids the risk of IRS penalties. Given the increase in the percentage, some employers may find it easier to meet this standard in 2027 than they did in 2024 or 2025.
The "Pay" Option:
Some organizations may find the cost of subsidizing premiums to the 10.22% level to be more expensive than the actual IRS penalties. However, this is a risky strategy. The IRS enforces two primary penalties under Section 4980H:
- The (a) Penalty: This applies if an ALE fails to offer MEC to at least 95% of its full-time employees and at least one full-time employee receives a premium tax credit (PTC) through the health insurance marketplace.
- The (b) Penalty: This applies if the employer offers coverage, but that coverage is either unaffordable (exceeds 10.22% in 2027) or fails to provide minimum value, and an employee subsequently receives a PTC.
Industry analysts note that while the affordability percentage has increased, the dollar amounts for these penalties are also adjusted annually for inflation. Therefore, an employer opting to "pay" might face a higher per-employee fine in 2027 than in previous years, even if the affordability percentage is more lenient.
Industry Reactions and Expert Analysis
Benefits consultants and legal experts have noted that the jump to 10.22% is a double-edged sword. On one hand, it provides fiscal relief to employers who have been struggling with the aggressive subsidy requirements of 2024 (8.39%). On the other hand, shifting more of the cost onto employees could impact talent retention in a competitive labor market.
"The increase to 10.22% gives HR directors a bit more breathing room in their 2027 budgeting," says one senior benefits strategist. "However, organizations must be careful. Just because a plan is legally ‘affordable’ doesn’t mean it is perceived as ‘accessible’ by the workforce. If the employee contribution rises too sharply, we may see a decrease in plan participation, which could affect the overall risk pool of the group."
Furthermore, for employers with non-calendar year plans, the transition period requires meticulous record-keeping. A plan year that begins in July 2026 will continue to use the 9.96% threshold until the new plan year begins in July 2027. This "staggered" compliance requires payroll systems to be highly adaptable to avoid accidental under-contribution.
Broader Economic Implications
The IRS’s decision to raise the threshold to 10.22% reflects broader economic shifts, including the rising cost of medical care and the general inflationary environment. By allowing the affordability percentage to rise, the federal government is effectively acknowledging that health insurance premiums are consuming a larger share of the average American household’s budget.
For the broader economy, this may lead to a slight reduction in employer spending on health benefits, potentially freeing up capital for wage increases or capital investment. Conversely, it places more financial responsibility on the individual employee. For low-to-mid-income workers, a 10.22% cap on premiums—plus deductibles and co-pays—represents a significant financial commitment.
Conclusion for Stakeholders
As organizations prepare for the 2027 fiscal year, the IRS Revenue Procedure 2026-26 serves as a critical guidepost. ALEs must verify their FTE counts to confirm their status, select the most advantageous safe harbor, and recalibrate their ICHRA or group plan contributions to align with the 10.22% mandate.
Failure to adapt to these changes by the start of the 2027 plan year could result in significant ESRP liabilities. With the IRS continuing to modernize its enforcement of the ACA through automated "Letter 226J" assessments, compliance is no longer a matter of "if" the agency will notice, but "when." Employers are encouraged to consult with benefits administrators and legal counsel to ensure that their 2027 offerings remain both competitive and compliant.
