Do Cash-in-Lieu Opt-Out Payments Count Against ACA Affordability?

An unconditional cash opt-out payment gets added to an employee's health plan contribution when the IRS tests ACA affordability, a rule many small employers do not know about until a penalty letter arrives.

Quick Answer (as of 2026): An employer's cash-in-lieu opt-out payment counts against ACA affordability unless it qualifies as an eligible opt-out arrangement under IRS Notice 2015-87. An unconditional opt-out payment gets added to the employee's required contribution, while a conditional payment, one that requires proof of other coverage, does not. The distinction can turn an affordable plan into an unaffordable one.

A small business that pays employees $150 a month to decline its health plan usually assumes that payment has nothing to do with whether the plan itself is affordable under the Affordable Care Act. For an applicable large employer, that assumption is often wrong. The IRS treats certain cash-in-lieu opt-out payments as an addition to the employee's health plan cost, not a separate perk, and getting the distinction wrong is one of the more common reasons an employer receives an unexpected Letter 226-J.

What Is a Cash-in-Lieu Opt-Out Payment?

A cash-in-lieu opt-out payment is money an employer pays an employee who declines the employer's health plan, usually added to the employee's paycheck as taxable cash. Employers offer these payments to reward employees who have coverage elsewhere, often through a spouse's plan, and to reduce the number of people enrolled in the company plan. A typical opt-out payment runs $50 to $200 a month, though the exact figure varies widely by employer and industry.

The payment is taxable income to the employee in almost every design, since it is cash the employee receives regardless of what they spend it on. That taxable treatment is separate from the affordability question this guide covers. An opt-out payment can be fully taxable and still change how the IRS measures whether the underlying health plan is affordable.

Why Do Opt-Out Payments Affect ACA Affordability?

An unconditional opt-out payment affects ACA affordability because the IRS requires an applicable large employer to add it to the employee's required plan contribution before testing that contribution against the affordability percentage. IRS Notice 2015-87 set this rule in 2015, and the final regulations that followed kept it in place. The logic is that an employee choosing between enrolling in the plan or taking the cash is really choosing between two dollar amounts, the plan's cost or the cash they give up, so the IRS treats the forgone cash as part of what coverage actually costs that employee.

This matters because the <a href="/blog/aca-employer-mandate-2026-requirements">ACA employer mandate</a> only protects an employer from a 4980H(b) penalty if the plan's employee contribution stays under the affordability percentage, 9.96% of income for 2026 plan years and 10.22% for plan years beginning in 2027, under one of the IRS safe harbors. An opt-out payment that gets added to the contribution can push a plan that looked affordable past that line without the employer changing a single premium dollar.

What Is the Difference Between an Unconditional and a Conditional Opt-Out Payment?

An unconditional opt-out payment goes to any employee who simply declines the employer's health plan, with no further requirement, and that type must be added to the employee's contribution for affordability testing. A conditional opt-out payment, sometimes called an eligible opt-out arrangement, requires the employee to show proof of other minimum essential coverage for themselves and every dependent who would otherwise be eligible under the employer's plan, and that type is excluded from the affordability calculation entirely.

The proof requirement is the whole difference. An employer who pays the opt-out bonus to anyone who checks a box declining coverage has an unconditional arrangement. An employer who requires a copy of the spouse's insurance card, an attestation naming the other plan, or similar documentation before releasing the payment has a conditional, eligible opt-out arrangement. Notice 2015-87 also gave employers transition relief for opt-out arrangements adopted on or before December 15, 2016, but that relief applied only to those specific legacy arrangements and does not extend to a plan design adopted or changed today.

How Do You Calculate Affordability When an Opt-Out Payment Applies?

Add the unconditional opt-out payment to the employee's monthly plan contribution, then compare that combined figure to the dollar ceiling set by whichever <a href="/blog/aca-affordability-percentage-guide">ACA affordability safe harbor</a> the employer uses. Consider a plan year beginning January 1, 2027, where an employer's lowest-cost self-only plan costs an employee $130 a month, comfortably under the $135.92 monthly ceiling the federal poverty line safe harbor sets for calendar-year 2027 plans (10.22% applied to the 2026 federal poverty guideline of $15,960 for the 48 contiguous states, divided by 12).

That $130 contribution looks affordable on its own. But if the same employer also pays a $150 monthly unconditional opt-out payment to employees who decline the plan, the IRS adds that $150 to the $130 contribution, producing an effective cost of $280 a month for affordability testing, well past the $135.92 ceiling. The plan is unaffordable under the FPL safe harbor for every full-time employee exposed to that opt-out offer, even though nothing about the plan's actual premium changed.

Does an Eligible Opt-Out Arrangement Avoid This Problem?

Yes. Converting an unconditional opt-out payment into an eligible opt-out arrangement, by adding the proof-of-other-coverage requirement, removes the payment from the affordability calculation entirely. In the example above, the same $150 payment made conditional on the employee showing proof of coverage through a spouse's plan would not be added to the $130 contribution, and the plan would pass the FPL safe harbor at $130 a month exactly as before.

This is usually the simplest fix available to an employer who discovers an existing opt-out arrangement is unconditional. It does not require lowering the opt-out amount or restructuring the health plan itself, only adding a documentation step to the enrollment process and updating the plan document and employee communications to describe the new condition clearly before the next plan year begins.

How Do Opt-Out Payments Interact With a Section 125 Plan?

An opt-out payment usually sits outside a <a href="/blog/section-125-cafeteria-plan-2026-guide">Section 125 cafeteria plan</a>'s pre-tax elections, since the payment itself is taxable cash rather than a pre-tax benefit, but the plan document should still describe both options clearly. An employee choosing to enroll and pay their share pre-tax reduces taxable W-2 wages and generates the employer's FICA recapture described in our <a href="/blog/maximizing-fica-tax-savings">FICA tax savings guide</a>, while an employee taking the opt-out payment instead receives fully taxable cash with no FICA reduction for either party. Building both paths into the same Section 125 plan document keeps enrollment, payroll coding, and nondiscrimination testing consistent, and it gives the employer one place to document whether the opt-out arrangement is conditional or unconditional for the affordability records an auditor or the IRS might request later.

What Should Employers Do Before Open Enrollment?

Applicable large employers should inventory every opt-out or cash-in-lieu payment currently offered, confirm in writing whether each one requires proof of other coverage, and rerun the affordability math for any unconditional payment before finalizing 2027 contribution amounts. An employer that finds an unconditional arrangement has two practical paths: add the proof-of-coverage condition to convert it into an eligible opt-out arrangement, or lower the employee's plan contribution enough that the combined contribution-plus-opt-out figure still clears the applicable safe harbor. Either fix is far less expensive than the 4980H(b) penalty risk of leaving an unconditional opt-out payment in place and discovering the problem only after a <a href="/blog/irs-letter-226-j-employer-guide">Letter 226-J</a> arrives.

Frequently Asked Questions

What is an unconditional opt-out payment?
An unconditional opt-out payment is cash an employer pays any employee who declines the company health plan, with no further requirement attached. Because the employee does not have to prove anything to get it, the IRS treats it as part of what coverage effectively costs that employee and adds it to their plan contribution for ACA affordability testing.
How do I make my opt-out payment an eligible opt-out arrangement?
Require the employee to show proof of other minimum essential coverage, for themselves and any dependent who would otherwise be eligible under your plan, before releasing the opt-out payment. Once that proof requirement is in the plan document and actually enforced, the payment becomes a conditional, eligible opt-out arrangement and is excluded from the affordability calculation entirely.
Does an opt-out payment affect small employers too?
The affordability rule for opt-out payments only carries a penalty risk for applicable large employers, generally those with 50 or more full-time equivalent employees, since only ALEs face the ACA employer mandate's 4980H penalties. A small employer below that threshold can still offer an unconditional opt-out payment without ACA affordability consequences, though the payment remains taxable income to the employee either way.
Is an opt-out payment the same as a wellness incentive?
No. An opt-out payment is cash paid for declining health coverage entirely, while a wellness incentive is a reward for completing a health-related activity, such as a biometric screening, regardless of whether the employee enrolls in the plan. The two are governed by different rules, and a wellness incentive generally does not get added to the affordability calculation the way an unconditional opt-out payment does.
What happens if an employer gets the opt-out payment calculation wrong?
An employer whose plan turns out to be unaffordable because of an unconditional opt-out payment can face a Section 4980H(b) penalty for each full-time employee who was offered that arrangement, went without affordable coverage, and received a premium tax credit on the ACA marketplace. The IRS typically flags this through a Letter 226-J, which arrives well after the plan year in question has already closed.
Does the opt-out payment amount matter, or just whether it is conditional?
Both matter. Whether the payment is conditional determines if it gets added to the affordability calculation at all. If it is unconditional and therefore included, the dollar amount then determines how much it raises the employee's effective contribution, and a larger unconditional payment creates more room for the combined figure to exceed the applicable safe harbor ceiling.
Can an employer offer different opt-out arrangements to different employee groups?
Yes, an employer can structure opt-out payments differently for different classes of employees, similar to how ACA safe harbors can vary by class, but each arrangement should be documented and tested on its own terms. Mixing conditional and unconditional opt-out payments across different groups within the same plan adds administrative complexity, so most employers standardize on one approach across the whole workforce.

Employees typically see $70 to $110 more in take-home pay every month with a Section 125 plan.
