IRS Proposes ACA Subsidy Verification Rules for 2027

Treasury and the IRS proposed rules on October 14 that limit premium tax credits to citizens, nationals and some lawfully present noncitizens starting in 2027.

If you run a store and buy your own health plan on the marketplace, the citizenship language is not the part to read twice. The proposal also writes the end of the repayment cap on excess advance credits into the regulations, and it adds income and family-size verification for advance payments starting in 2028. For a high-ticket owner whose fourth quarter can carry a big share of the year, the income guess you type in during open enrollment is a number the IRS can collect against, dollar for dollar. I cover the money and tax side of running a store at Ecommerce Paradise for exactly this reason.

Below: what the proposal says, why the repayment cap already applies to your 2026 return, the math on a seasonal store, and six moves to make before open enrollment starts November 1. This is reporting plus my opinion. I’m not a tax or legal advisor, so run your numbers past a CPA.

IRS Premium Tax Credit Rules: What Treasury Proposed Oct. 14

According to IRS release IR-2026-121, Treasury and the IRS issued proposed regulations to implement the premium tax credit changes in the 2025 tax law, which the agencies now call the Working Families Tax Cuts. The rules restrict eligibility to U.S. citizens, U.S. nationals and certain lawfully present noncitizens, and they add eligibility checks and new verification criteria for advance payments. HHS will issue parallel proposed rules covering how the exchanges carry out those checks, per the release.

Treasury Secretary Scott Bessent said taxpayers “should not be forced to subsidize health care for people who are ineligible.” IRS Chief Executive Officer Frank Bisignano said the verification measures “are designed to curb improper claims.” The release also cites CMS, which says it removed more than 760,000 unverified “phantom” enrollees from the ACA rolls, with $2.2 billion in savings.

The operating detail sits in the proposed rule itself, REG-101576-26. The Federal Register public inspection copy was filed October 14 and is scheduled for publication October 15. It is 60 pages, and the text I could read was truncated, so I cannot tell you whether it has a dedicated rule for self-employed income estimates. These are the provisions that matter to a store owner:

Repayment cap: The proposal eliminates the limit on repaying excess advance credits for taxable years beginning after December 31, 2025. Treasury estimates about 3.7 million returns in 2028 will include an excess repayment.

Income verification: For taxable years beginning after December 31, 2027, a month with advance credits counts as a coverage month only if the exchange verifies residence, citizenship or lawful presence, household income, family size, and the absence of other minimum essential coverage. Exchanges generally verify a reported income change before raising the credit, but they may lower it immediately, before verification, if you report higher income.

Prior-year filing: Under the proposal, a month does not count as a coverage month if the exchange fails to enforce the rule that you reconciled the prior year’s advance credits. That also starts with taxable years beginning after December 31, 2027.

Special enrollment: Plans bought through an income-based special enrollment period would not count as qualified health plans for the credit unless tied to a qualifying event. That applies to plan years beginning on or after the publication date.

Comments are due 45 days after publication, which works out to November 29 by my count. A telephonic public hearing is set for December 8 at 10 a.m. ET, and requests to speak are due on the same 45-day clock.

Why the Repayment Cap Is Gone Before These Rules Even Land

The cap on repayment did not die because of this proposal. The 2025 tax law, Public Law 119-21, removed it, and the proposed rule says statutory provisions take effect for years beginning after December 31, 2025 and override conflicting regulations. The regulation catches up to what Congress already did.

Louise Norris at healthinsurance.org writes that starting with the 2026 plan year, all excess advance credits must be repaid. If household income lands above 400% of the federal poverty level, you repay all of the credits paid on your behalf, because no subsidy is available above that line. Her page was last updated April 22, 2026.

The 400% line matters again because the enhanced credits expired on January 1, 2026, according to the Congressional Research Service as cited by 24/7 Wall St. Per that October 11 report, the cliff for 2026 coverage is $62,600 for a single filer and $84,600 for a married couple, based on the 2025 poverty guideline of $15,650.

The baseline is the old cap. The same report, citing KFF, says a single filer between 300% and 400% of the poverty level repaid at most $1,625 on 2025 returns. For 2026 returns that ceiling no longer exists.

Its worked example is a 62-year-old early retiree who estimated $58,000 of income, received a $7,423.20 credit, and ended the year at $63,000. She repays the full $7,423.20, and with ordinary income tax on the extra $5,000 the report puts her total cost at $8,023.20. That is one illustration from one outlet, not a typical case.

Open enrollment for 2027 coverage runs November 1 through January 15 on HealthCare.gov, with December 15 as the deadline for coverage that starts January 1. State-run exchanges set their own dates.

As for dissent, the administration’s case is fraud control, and Treasury’s own figures on removed enrollees are the support it offers. I found no published reaction from health policy groups or tax professionals to this specific proposal as of this morning, so there is no counterargument to quote yet. The comment window is open for exactly that. Also note the new income verification would not start until 2028 under the proposal, so nothing about what you sign this November changes except the uncapped repayment and the special enrollment rule.

What Uncapped ACA Repayment Means for a Seasonal Store Owner

Everything from here is my read, not reported fact.

Your marketplace subsidy runs on projected modified adjusted gross income, which for a sole proprietor or single-member LLC owner tracks net profit, not revenue. High-ticket stores swing that number hard. A handful of orders at $3,000 to $8,000 each can move a month, and a supplier invoice paid in December instead of January can move a year. Q4 is the swing quarter, and retailers like Lowe’s are already starting Black Friday early. I covered that in Lowe’s Starts Black Friday Oct. 29.

Here is hypothetical math, not a reported case. A single owner projects $58,000 of income for 2026 and takes the full advance credit each month. Through September the store has netted $40,000, then Q4 delivers another $25,000. Final income is $65,000, which is above the $62,600 cliff in the 24/7 report, so every dollar of advance credit comes back with the return. Per the 24/7 report the clawback above 400% has no cap, and for 2026 returns the caps below that line are gone too.

Three scenarios, with thresholds. If final income stays under 400%, you repay only the gap between the advance credits and the credit you qualified for. If it crosses 400%, you repay everything. If you left the projection alone while the store ran hot, the repayment shows up as a surprise in the same spring that your tax bill does.

The asymmetry is the whole point. Overestimating income costs you cash flow, because you pay more of the premium each month. According to healthinsurance.org you can also take less than the full advance credit and claim the shortfall at tax time. Underestimating income can cost you the entire credit. My read is that for a seasonal store, the cheap mistake is guessing high.

The reverse trap is lenders. If you push reported income down to protect a subsidy, you also push down what a mortgage underwriter sees. I broke down how that works in my self-employed mortgage requirements checklist.

You also get levers on the income side. The 24/7 report says deductible traditional IRA, HSA and SEP contributions can lower the income figure, and that a 2026 IRA contribution can be made until April 15, 2027. I compared the owner-friendly retirement accounts in my Solo 401(k) vs SEP IRA guide. The 2026 caps are on my page covering SEP IRA contribution limits. How any of it interacts with your subsidy is a CPA question, not a blog question.

What I’d do is stop treating health coverage as a once-a-year form and start treating it as a line in the monthly profit review. That requires a profit number you can trust. Finaloop is an accounting tool aimed at ecommerce stores, and a monthly profit view is what you want from whatever you pick.

Prefer the classic route? QuickBooks still works for many stores. My QuickBooks alternatives breakdown shows where it does not.

The rest of the problem is the store itself. Thin, unpredictable revenue is hard to forecast no matter how good the books are, and the long sales cycles on big-ticket items make it worse. I wrote about that in how to market high-ticket products with long sales cycles.

The macro backdrop does not help. I covered consumer sentiment at 46.3 with durables buying sinking. I also covered the September CPI print at 3.7% before the Fed vote. Forecasting Q4 at those readings is guessing with a straight face.

That is the case for a store built to produce steadier income in the first place. My team builds and runs high-ticket stores through the turnkey done-for-you service, and one of the first things I want on any store is a profit number you can read in five minutes. If you already have a store but the revenue is too thin to forecast, the scaling service is what my team does for existing stores.

Before Nov. 1: Six Steps for Store Owners on Marketplace Coverage

Here are six moves, in the order I’d make them.

Pull year-to-date net profit by month and compare it with the income on your current marketplace application. Your Shopify admin gives you the sales and cost data, and your books give you the profit. If the gap is more than a few thousand dollars, update your projection on HealthCare.gov now instead of waiting for tax time.
Check the cliff. For 2026 coverage the 400% line in the 24/7 report is $62,600 single and $84,600 for a couple. If Q4 will push you across it, ask the marketplace about stopping or reducing advance payments for the rest of the year, and ask a CPA what that does to your return.
Build the 2027 projection from three cases, low, base and high, before open enrollment opens on November 1. Use base-to-high for the number you submit, or choose to take only part of the credit monthly and claim the rest at filing. My guide to filing taxes as an ecommerce seller covers where the credit reconciliation lands on the return.
Ask your CPA about timing. Deductible expenses and retirement contributions both move the income line, and my breakdown of which ecommerce expenses you can deduct is a decent list to bring to that call. If you want a retirement account to hold those contributions, a broker such as Schwab is one place to start.
Separate the money. Keep a tax and health-cost bucket in its own business account so a strong December does not get spent before the April bill. I walked through the setup in how to open a Mercury account. If you also run payroll, Gusto puts wages on the books month by month, which feeds the same projection.
If you spend part of the year abroad, read the residence language before you renew. The proposal puts residence verification inside the coverage-month test. A nomad health policy such as SafetyWing is worth pricing for the months you are abroad. If you want a second set of eyes on your store’s numbers, book a discovery call.

Frequently Asked Questions

Does this proposal change my 2026 marketplace plan?
Not by itself. The uncapped repayment applies to 2026 returns because the 2025 tax law set it, and the proposed rule says statutory provisions take effect for years beginning after December 31, 2025. The proposal puts that in the regulations.

When would the new income verification start?
Under the proposal, for taxable years beginning after December 31, 2027. The special enrollment change applies to plan years beginning on or after the publication date, so that one is nearer.

How much can I owe if I underestimate my income?
With the cap gone, you repay the full excess, and if your income lands above 400% of the poverty level you repay all of the advance credits, per healthinsurance.org. Your total depends on your income, family size and state.

Can retirement contributions lower the income figure?
According to the 24/7 Wall St. report, deductible traditional IRA, HSA and SEP contributions can reduce it. The rules differ by account, so check the Solo 401(k) contribution limits and talk to a CPA before you move money.

How do I make store income less lumpy?
I’d start with niches that sell year-round instead of one season. My free niches list at ecommerceparadise.com/niches is where I’d begin. The high-ticket niches list goes deeper.

I split the year abroad. Does this matter to me?
Possibly, because the proposed rule includes residence verification as part of a coverage month. I compared options in my nomad insurance vs travel insurance guide. This is general information, not legal or tax advice.
