ACA Subsidy Calculator 2026–2027

Who the 400% cliff hits hardest

From 2021 through 2025, Marketplace health insurance came with enhanced premium tax credits. No household paid more than 8.5% of its income for the benchmark silver plan, however much it earned. Those enhancements expired at the end of 2025, and as of October 2026 Congress hasn’t restored them for 2027. For 2026 and 2027 coverage, the original Affordable Care Act rules are back, and so is one of the harshest features in the tax code: the subsidy cliff.

This section covers:

• what the cliff is and who it hits hardest;
• the 2027 and 2026 income limits by household size;
• the legal, practical ways to keep your income on the right side of the line.

What is the ACA subsidy cliff?

The ACA subsidy cliff is the income line, 400% of the federal poverty line, above which the premium tax credit stops entirely. Under current rules, the premium tax credit is available to households with income between 100% and 400% of the federal poverty line. Inside that range, you pay a set percentage of your income for the benchmark plan and the credit covers the rest. That percentage runs from 2.15% to 10.22% for 2027 under IRS Rev. Proc. 2026-26, up from 2.10% to 9.96% in 2026.

Above 400%, the credit doesn’t shrink gradually. It disappears. A household at 399% of the poverty line can receive thousands of dollars of help. The same household at 401% receives nothing and pays the full premium.

The 2027 and 2026 income limits

Each coverage year uses the previous year’s HHS poverty guidelines. For 2027 coverage, that’s $15,960 for one person plus $5,680 for each additional person in the 48 contiguous states and Washington, D.C. For 2026 coverage, it was $15,650 plus $5,500:

Alaska and Hawaii use higher guidelines. For 2027 coverage, they’re $19,950 plus $7,100 per person in Alaska and $18,360 plus $6,530 in Hawaii, so their limits are higher too. See every household size in our ACA income limits table.

Who is hit hardest by the cliff?

The cliff doesn’t affect everyone equally. What you lose depends on how expensive the benchmark plan is where you live and at your age. Several groups feel it most:

• Early retirees aged 50–64. Insurers can charge older adults up to three times what they charge younger ones, so benchmark premiums for a couple in their 60s often exceed $2,000 a month. Losing the credit can mean paying $20,000 or more a year for coverage.
• People in high-cost areas. Rural counties and some states have much higher benchmark premiums.
• Self-employed people and small-business owners, whose income swings from year to year and can land just over the line.
• Couples with one income just over the limit. Two people need MAGI of $86,560 or less for 2027 coverage ($84,600 in 2026). That is well within the range of a single professional salary.

An example for 2027. A married couple in their early 60s has a benchmark premium of $2,000 a month:

• At a household income of $86,000, just under the limit, they receive a credit of about $1,268 a month, or $15,211 a year.
• At $87,000 they receive nothing.
• Under the expired 2021–2025 rules, they would receive about $1,384 a month at $87,000.

Why a few dollars matter: what counts as income

The test uses your household’s modified adjusted gross income (MAGI) for the year of coverage. For the premium tax credit, MAGI is your adjusted gross income plus:

• untaxed foreign earned income and housing costs you excluded;
• tax-exempt interest, such as municipal bond interest;
• the untaxed part of Social Security benefits.

It includes the income of everyone in your tax household who is required to file a return. Because the limit is a hard cliff, the details matter. A small capital gain distribution, a forgotten 1099 or a Roth conversion can move you over the line.

Seven ways to keep MAGI under the cliff

These are ordinary, legal planning moves. What fits you depends on your situation, so check with a tax professional when thousands of dollars are at stake.

1. Contribute to a traditional 401(k), 403(b) or 457 plan. Pre-tax contributions reduce AGI dollar for dollar, up to the annual limit. Catch-up contributions are available from age 50.

2. Make a deductible traditional IRA contribution if you’re eligible. Eligibility depends on whether you or your spouse has a workplace plan, and on your income.

3. Fund a Health Savings Account. HSA contributions reduce AGI. Starting in 2026, bronze and catastrophic Marketplace plans can be paired with an HSA, which gives more enrollees this option.

4. If you’re self-employed, use the business deductions built for this.

   • Contributions to a SEP-IRA or Solo 401(k).
   • The deductible half of self-employment tax.
   • The self-employed health insurance deduction.

   All three reduce AGI.

5. Manage capital gains. Harvest losses to offset gains, or spread large sales across tax years. Check mutual fund distribution estimates before year-end.

6. Time conversions and withdrawals. Roth conversions and traditional IRA withdrawals add to MAGI. In the years before Medicare, some early retirees live on cash savings or Roth contributions instead, then convert after 65. Our guide to ACA subsidies for early retirees shows which retirement income counts, with a worked example.

7. Time other income where you legitimately can. For example, the year you invoice a large project, take a bonus or sell a business asset.

What doesn’t help

Some deductions lower your tax bill but don’t lower MAGI, so they don’t move you back under the cliff:

• The standard deduction and itemized deductions. These come after AGI.
• The new 2025–2028 deductions for tips, overtime, car loan interest and seniors. They are taken after AGI on Schedule 1-A; see our Schedule 1-A calculator for their tax value.
• Tax credits, which reduce tax, not income.

Reconciliation is stricter from 2026

Most people receive the credit in advance, paid monthly to their insurer, based on the income they estimate at enrollment. At tax time, Form 8962 compares the advance payments with the credit you actually qualify for.

Before 2026, households under 400% had caps on how much excess credit they had to repay. Starting with 2026 tax years, those repayment caps no longer apply. If your income comes in higher than estimated, you repay the full excess. And if you end the year over 400%, that can mean repaying every dollar of advance credit.

Two habits protect you:

• Estimate conservatively and update the Marketplace when your income changes during the year. Your advance credit will then be adjusted.
• Track your MAGI in the fourth quarter. You still have time to make retirement or HSA contributions, and to time sales, before December 31.

If you’ll be over the limit anyway

• Compare bronze plans, which can cost far less than the benchmark silver plan, and check HSA eligibility.
• Look at other coverage. An employer plan, a spouse’s plan or COBRA may cost less.
• Check state programs. A few states offer their own premium assistance on top of, or instead of, the federal credit. Your state exchange will show it.
• Plan for next year. Once you know you’re close to the line, contributions made early in the year are easier than a scramble in December.

Keep an eye on Congress

The expiration of the enhanced credits has been the subject of repeated debate in Congress, and as of October 2026 they haven’t been restored. The rules could still change, and we update our ACA subsidy calculator when they do. It shows your credit for 2027 or 2026 under current law and under the expired enhanced rules.
