ACA Subsidy Cliff 2027: How to Stay Under the 400% Line
One dollar over can cost you every dollar of your subsidy. For 2027 coverage, the premium tax credit ends cold at $63,840 for a single person — no phase-out, no partial credit. Here's what counts toward the line, the legitimate levers that keep you under it, and what to do if you're over anyway.

The ACA subsidy cliff is the hard edge of premium tax credit eligibility: earn even $1 over 400% of the federal poverty level and your credit for the year isn't reduced — it's $0. After several years of a gentler phase-out, the cliff is back for 2027 coverage under current law, which makes the ACA subsidy cliff 2027 shoppers face the single most expensive line in the tax code for people who buy their own health insurance. For one person, that line sits at $63,840.
Why is it back? The enhanced credits in place from 2021 through 2025 have expired and are not back for 2027 unless Congress acts — so subsidies are smaller than they were in 2025, and the 400% cutoff is absolute again. (The full story is in our breakdown of why 2027 premiums are higher; if you fought this battle last year, our 2026 subsidy cliff guide covers the prior-year numbers.) With Open Enrollment for 2027 coverage running November 1, 2026 – January 15, 2027, the time to plan your income — not just your plan — is before you enroll.
Quick answer: The ACA subsidy cliff 2027 threshold is 400% of the federal poverty level — $63,840 for a single person, roughly $132,000 for a family of four. Earn $1 more and your premium tax credit drops to $0 under current law. Open Enrollment runs November 1, 2026 – January 15, 2027; enroll by December 15, 2026 for January 1 coverage.

The ACA Subsidy Cliff 2027: What Does $1 Over Cost You?
At $63,840 of income, a single enrollee's benchmark Silver premium is capped at 10.22% of income — roughly $545 a month. At $63,841, there is no cap: the credit is $0 and you pay whatever the carrier charges. That is the entire cliff — and it's why a year-end bonus, one good freelance quarter, or a surprise mutual fund distribution can quietly cost thousands.
| Your 2027 Income (Single Filer) | Where That Lands | What Happens to Your Credit |
|---|---|---|
| $60,000 | About 376% of FPL — under the line | Credit applies — benchmark Silver stays capped on the 2.15%–10.22% sliding scale |
| $63,840 | Exactly 400% of FPL — the last eligible dollar | Credit still applies — benchmark Silver capped at 10.22% of income, roughly $545/month |
| $63,841 | $1 over the line | Credit is $0 — you pay the full, unsubsidized premium all year |
| $70,000 | Comfortably over 400% of FPL | No credit — compare full-price on-exchange and off-exchange plans instead |
Two notes on reading that table. First, the credit doesn't just appear at the top of the scale: from 100% of FPL ($15,960 single) up to 400%, your expected contribution slides from 2.15% to 10.22% of income, so credits shrink gradually until the line — then vanish. Second, this page is deliberately not the full eligibility chart. For every household size and income band, see our 2027 ACA subsidy income limits chart; this page is about staying on the right side of it.
What Counts Toward MAGI for ACA Subsidies?
Subsidy eligibility is measured by MAGI — modified adjusted gross income — for your whole tax household, not just your paycheck. For ACA purposes, MAGI generally means your adjusted gross income plus tax-exempt interest, untaxed Social Security benefits, and excluded foreign income. It is a broader number than most people expect, which is exactly how households get surprised at the line.
What generally counts: W-2 wages, net self-employment income, interest and dividends, capital gains, rental income, unemployment compensation, and most withdrawals from traditional retirement accounts. What generally doesn't: qualified Roth withdrawals, child support received, SSI, and gifts. The rules have edges — confirm your specific number with your CPA before you bet a subsidy on it.
Two details trip people up every year. It's household income — your spouse's December raise counts against your line even if the plan only covers you. And what you enroll with is a projection of 2027 income that gets reconciled on your 2027 federal return. Guess low near the cliff and you can be asked to repay credits at tax time — with the cliff back, finishing the year even $1 over can mean repaying all of them. Income re-verification matters more this year than it has since 2020.
How to Lower Your MAGI Before the December 15 Deadline
If your income hovers near $63,840 (single) or roughly $132,000 (family of four), there are legitimate, boring, IRS-recognized ways to bring MAGI down. None of what follows is tax advice — every one of these is a strategy to confirm with your CPA. But these are the levers that actually move the number:
💰 Pre-Tax 401(k) / 403(b)
Traditional pre-tax deferrals generally reduce the wages that flow into MAGI, dollar for dollar, up to the annual IRS limit. Roth deferrals do not — they're after-tax. Raising your deferral percentage is the most common cliff lever we see. Confirm with your CPA.
🏦 Traditional IRA
Deductible traditional IRA contributions generally reduce AGI — but deductibility depends on your income and whether you're covered by a workplace plan. Near the line, that deduction can be the difference between a capped premium and full price. CPA territory.
🏥 HSA Contributions
If you pair an HSA-qualified high-deductible plan with an HSA, contributions generally lower MAGI dollar for dollar — and the account doubles as a medical emergency fund. One of the cleanest cliff tools, if the plan type fits how you use care.
📅 Self-Employment Timing
Freelancers and business owners can sometimes shift the year income lands — a January invoice instead of a December one — or accelerate deductible business expenses. Powerful, but timing rules are strict; run every move by your CPA first.
One timing note: what counts for 2027 coverage is your 2027 MAGI. The projection you give the marketplace between November 1 and January 15 has to match how you'll actually run the year — deferral rates, HSA payroll elections, invoice timing. If you're self-employed, your income is the lumpiest and your levers are the strongest; our self-employed Open Enrollment 2027 guide was written for exactly this problem.
Straight talk — the auto-renewal trap: do nothing this fall and most marketplaces re-enroll you in the same or a similar plan automatically. With credits smaller and the cliff back, last year's plan at last year's income estimate can be this year's overpay — or this year's surprise repayment bill. Never let a 2027 plan auto-renew without a 15-minute re-shop and a fresh income projection. Enroll by December 15, 2026 and coverage starts January 1; enroll December 16 – January 15 and it starts February 1 — a one-month gap. Miss January 15 entirely and you'll generally need a qualifying life event to enroll at all. More traps like this in our Open Enrollment mistakes guide.
What If You End Up Over the Cliff Anyway?
Going over 400% of FPL is not a coverage death sentence — it just changes how you shop. With no credit in play, the marketplace's main advantage disappears, and the smart move is to compare the whole menu: on-exchange plans and off-exchange plans bought directly from carriers, which skip the marketplace paperwork entirely and, in some states, include plan designs the exchange doesn't list.
Full-pay shoppers should judge plans on network, drug coverage, and worst-case total cost — not sticker premium alone. Our guide for households over the subsidy line walks through the playbook. And if your income lands near the line rather than far over it, don't concede the credit without checking the levers above — a licensed advisor can run both scenarios side by side, free.
