ACA subsidies in early retirement work differently for 2026 than they did for the prior four years: the enhanced credits from the American Rescue Plan and Inflation Reduction Act expired after 2025, so the 400% federal poverty line (FPL) “subsidy cliff” is back, and a household one dollar over that line receives zero premium tax credit (Source: CRS Report R48290, updated Dec. 10, 2025; 26 U.S.C. 36B(c)(1)(E)). For anyone who retires before 65 and buys marketplace coverage, managing Modified Adjusted Gross Income (MAGI) is a defining part of the picture.
For 2026, ACA premium tax credits phase out entirely above 400% of the federal poverty line. Coverage year 2026 uses the 2025 poverty guidelines, so the ceiling is about $62,600 for a single filer and $84,600 for a couple (the $15,650 single figure plus $5,500 per additional person). Cross the line by $1 and the credit drops to $0 (Source: 26 U.S.C. 36B(c)(1); 2025 HHS Poverty Guidelines).
What ACA subsidies mean for early retirees in 2026
ACA subsidies for early retirees are premium tax credits (PTCs) that lower the cost of marketplace health insurance between the day you leave employer coverage and the month you turn 65 and qualify for Medicare. Eligibility depends on household income measured as MAGI, not on net worth or assets (Source: 26 U.S.C. 36B(d)(2)). This makes income timing, rather than portfolio size, a factor to weigh with a qualified professional.

The most-affected group is middle-income adults aged 50 to 64. They are too young for Medicare and, once they stop working, too old to rely on employer coverage. Many carry substantial pre-tax retirement balances, and the withdrawals used to fund early retirement are the dollars that raise MAGI (Source: IRS Pub. 590-B, 2025).
Medicare eligibility at 65 closes the ACA-subsidy window. The planning years covered by this guide are the gap between an early retirement date and the first month of Medicare coverage, which for most people is the month they reach 65.
Why the ACA subsidy cliff came back for 2026
The subsidy cliff returned in 2026 because the temporary removal of the 400% FPL upper cap applied only to tax years beginning after Dec. 31, 2020, and before Jan. 1, 2026. That provision expired on schedule, and Congress did not extend it (Source: 26 U.S.C. 36B(c)(1)(E); CRS Report R48290, Dec. 10, 2025). The result is a return to the pre-2021 rules for benefit year 2026.
From 2021 through 2025, the American Rescue Plan and later the Inflation Reduction Act removed the hard income ceiling and, under the enhanced regime, capped the required premium contribution at 8.5% of income for households that would otherwise have been above the old ceiling. With expiration, 2026 reverts to the pre-2021 regime: a hard 400% FPL ceiling and higher applicable percentages up to 9.96% at the top of the range (Source: Rev. Proc. 2025-25).
The Congressional Research Service, in Report R48290 updated Dec. 10, 2025, states the enhanced credits expired after 2025 and were not extended, and that the FY2026 continuing-resolution law “did not affect expiration of the enhanced PTC” (Source: CRS Report R48290).
Legislative status as of mid-2026
As of July 2026, current federal law is the pre-2021 regime: the 400% FPL cliff applies for benefit year 2026. Bills to re-extend the enhanced credits have circulated, but the authoritative CRS analysis reflects that no extension had taken effect for 2026 as of its December 2025 update (Source: CRS Report R48290, Dec. 10, 2025). Any future extension by Congress could change the rules for 2027 and later, so early retirees planning multi-year income often confirm the enacted status before locking in estimates.
2026 income thresholds: 400% of the federal poverty line by household size
The 400% FPL ceiling is a central number for ACA subsidies in early retirement. It is built from the federal poverty guideline for your family size, and coverage year 2026 uses the 2025 guidelines. On the 2025 basis of $15,650 for one person plus $5,500 for each additional household member, 400% of FPL lands near the figures below (Source: 26 U.S.C. 36B(c)(1)(A); 2025 HHS Poverty Guidelines, 48 contiguous states and DC).
| Household size | 100% FPL (2025 guideline) | 400% FPL ceiling (2026 coverage) |
|---|---|---|
| 1 person | $15,650 | ~$62,600 |
| 2 people | $21,150 | ~$84,600 |
| 3 people | $26,650 | ~$106,600 |
| 4 people | $32,150 | ~$128,600 |
These figures apply to the 48 contiguous states and DC; Alaska and Hawaii use higher guidelines. The poverty guidelines used for a given benefit year are published by HHS and should be confirmed against the official guideline for your household size and state. The statutory ceiling itself, 400% of FPL, is fixed in law (Source: 26 U.S.C. 36B(c)(1)(A); 2025 HHS Poverty Guidelines).
Below the ceiling, the credit is calculated so that a household pays a capped percentage of income for the benchmark silver plan. For 2026 that applicable percentage rises with income, reaching 9.96% at the top of the eligible range, per the indexed table in Rev. Proc. 2025-25 (Source: Rev. Proc. 2025-25).
| Household income (% of FPL) | 2026 initial % | 2026 final % |
|---|---|---|
| Less than 133% | 2.10% | 2.10% |
| 133% to under 150% | 3.14% | 4.19% |
| 150% to under 200% | 4.19% | 6.60% |
| 200% to under 250% | 6.60% | 8.44% |
| 250% to under 300% | 8.44% | 9.96% |
| 300% to 400% | 9.96% | 9.96% |
The dollar effect of crossing the cliff can be meaningful. Because unsubsidized marketplace premiums for people in their late 50s and 60s are among the highest in the individual market, an older household that loses eligibility at the cliff can see its full premium assistance disappear for the year. The exact amount varies by age, plan, and rating area, so any specific dollar figure should be checked against a current quote (Source: illustrative only; individual results vary by rating area).
What counts toward MAGI (and what does not)
MAGI for the premium tax credit is adjusted gross income increased by three items: foreign earned income excluded under section 911, tax-exempt interest, and the portion of Social Security benefits not otherwise included in gross income (Source: 26 U.S.C. 36B(d)(2)(B)). Household income then adds the MAGI of anyone in your family size who was required to file a return (Source: 26 U.S.C. 36B(d)(2)(A)). Because it starts from AGI, most retirement income raises MAGI.
The distinction between income that counts and income that does not is where early-retirement planning happens. Roth withdrawals and spending from taxable savings, for example, are already-taxed dollars that generally do not add to AGI.
| Raises MAGI | Does not raise MAGI / can reduce it |
|---|---|
| Traditional IRA and 401(k) withdrawals (Source: IRS Pub. 590-B, 2025) | Qualified Roth IRA withdrawals |
| Roth conversions (taxed as ordinary income) (Source: IRS Pub. 590-B; Form 8606) | Withdrawals of cash savings (principal) |
| Realized capital gains | HSA contributions (deductible / pre-tax) |
| Rental and taxable investment income | Deductible traditional IRA or 401(k) contributions |
| Taxable pensions and a portion of Social Security (Source: 26 U.S.C. 86; 36B(d)(2)(B)) | Capital-loss harvesting (up to $3,000/yr offsets ordinary income) (Source: 26 U.S.C. 1211(b)) |
One practical caution for 2026: if advance credits (APTC) are set from an estimate and actual MAGI comes in higher, the excess must be reconciled on IRS Form 8962. Section 71305 of the One Big Beautiful Bill Act removed the repayment cap for tax years beginning after Dec. 31, 2025, so a household that underestimates MAGI may have to repay the full amount of excess advance credit with no dollar limit (Source: Rev. Proc. 2025-32; 26 U.S.C. 36B(f)).
Levers that reduce MAGI in the pre-Medicare years
Several tools can lower MAGI for a given year, which can keep a household under the 400% FPL ceiling or move it into a lower applicable percentage. Each has tradeoffs and eligibility rules, so these are described as options the rules allow, not recommendations, and are factors to weigh with a qualified professional.
- Health savings account (HSA) contributions. For 2026, individual-market Bronze and catastrophic plans are treated as high-deductible health plans, which makes enrollees HSA-eligible under the One Big Beautiful Bill Act (Source: IRS Notice 2026-5; OBBBA). Deductible HSA contributions reduce AGI and therefore MAGI (Source: 26 U.S.C. 36B(d)(2)).
- Deductible traditional IRA or workplace plan contributions. For 2026 the IRA limit is $7,500 with a $1,100 age-50 catch-up, and the 401(k)/403(b)/457(b)/TSP elective deferral limit is $24,500 with an $8,000 catch-up at 50-plus and $11,250 at ages 60-63 (Source: IRS Notice 2025-67). Deductibility phases out at higher incomes.
- Splitting stock sales across two tax years. Spreading a large realization can keep a single year’s MAGI under the ceiling.
- Capital-loss harvesting. Realized losses offset realized gains, and up to $3,000 of net loss can offset ordinary income per year, with the remainder carried forward (Source: 26 U.S.C. 1211(b)).
- Living on Roth and cash. Spending from Roth accounts and taxable savings principal funds the year without adding to MAGI.
Retirees over age 70½ who make charitable gifts sometimes use qualified charitable distributions, which are excluded from income up to $111,000 for 2026 and can lower MAGI relative to taking a taxable distribution and donating cash (Source: IRS Notice 2025-67; 26 U.S.C. 408(d)(8)).
The income floor: how going too low can cost you the subsidy
The 400% FPL ceiling gets most attention, but there is also a floor. Premium tax credits generally require household income of at least 100% of FPL, and in states that expanded Medicaid, adults under 65 below 138% of FPL are generally eligible for Medicaid rather than subsidized marketplace coverage (Source: 26 U.S.C. 36B(c)(1)(A); 42 U.S.C. 1396a(a)(10)(A)(i)(VIII)).
For an early retiree, that means suppressing MAGI too aggressively can drop you out of marketplace subsidies entirely and into Medicaid, which has different provider networks and asset-recovery rules for some services. The planning target is a band, not simply “as low as possible.”
State rules matter here. In states that did not expand Medicaid, the interaction differs and can create a coverage gap below 100% FPL. Because these rules vary by state and change over time, confirming your state’s expansion status for the benefit year is often part of the estimate.
The multi-year tradeoff: subsidies now versus RMDs and IRMAA later
Suppressing income to capture ACA subsidies before 65 can affect taxable income later, because dollars left inside a traditional IRA or 401(k) may continue to grow and must eventually come out. This is the crossover many guides mention but rarely quantify: subsidy amounts today can be offset by larger required minimum distributions (RMDs) and Medicare surcharges after 65 (Source: IRS Pub. 590-B, 2025).
A simplified illustration shows the mechanics. These figures are hypothetical and for education only; they are not projections of any client outcome.
| Strategy path | Ages 60-64 (pre-Medicare) | Age 73+ (RMD years) |
|---|---|---|
| Suppress MAGI, take no conversions | Keep MAGI under 400% FPL; may qualify for a premium tax credit that year | Larger pre-tax balance can mean larger RMDs, higher ordinary-income tax, and greater chance of Medicare IRMAA surcharges |
| Convert to Roth during 60-64 | Conversion is ordinary income; can raise MAGI over 400% FPL and forfeit the credit that year | Smaller pre-tax balance can mean smaller RMDs and lower IRMAA exposure |
The crossover point is the year where the subsidy given up by converting is smaller than the future tax and IRMAA cost of not converting. It depends on portfolio size, expected returns, tax brackets, and how many pre-Medicare years remain. There is no single answer; the arithmetic differs for each household, which is why a worked multi-year model matters more than a rule of thumb.
How this connects to Roth conversion timing
Because a Roth conversion adds ordinary income to AGI and therefore to 36B MAGI, one approach some early retirees consider is pausing conversions during the ACA-subsidy years and resuming after Medicare begins at 65, when the credit is no longer at stake (Source: IRS Pub. 590-B, 2025). This is educational framing of how the rules interact, not a recommendation; the right sequence depends on the full picture, including future required minimum distributions, and is a factor to weigh with a qualified professional.
IRMAA after 65: the surcharge that mirrors the cliff
IRMAA, the Income-Related Monthly Adjustment Amount, is a Medicare premium surcharge that applies once you enroll at 65 and is based on MAGI from the tax return filed two years earlier (Source: 42 U.S.C. 1395r(i); SSA). The income moves that affect ACA subsidies before 65, such as keeping MAGI low, can also affect IRMAA later, while large conversions or gains can trigger it.
This matters because the ACA and IRMAA rules can pull in different directions across the timeline. A retiree who defers all conversions to preserve subsidies until 65 may then face a compressed window before RMDs begin, and converting heavily right after 65 can lift MAGI into IRMAA brackets. The two systems are often modeled together rather than one at a time; the 2026 IRMAA brackets show where the surcharge thresholds sit.
Social Security taxation adds another layer, since a portion of benefits counts toward MAGI and rising income can increase how much of the benefit is taxed, an effect sometimes called the Social Security tax torpedo (Source: 26 U.S.C. 86; 36B(d)(2)(B)).
Timing: open enrollment and your first retirement year
Marketplace coverage for a calendar year is generally purchased during open enrollment in the preceding fall, and advance credits are set from your estimated household income for the coverage year. In a first retirement year, income often changes mid-year, so the estimate you give HealthCare.gov or your state exchange drives the advance credit you receive (Source: IRS Premium Tax Credit Q&A; Form 8962).
Because the excess-APTC repayment cap is gone for 2026, an overly optimistic income estimate that turns out too low can create a full repayment at tax time. Some retirees estimate conservatively and reconcile on Form 8962, while others adjust their exchange estimate during the year if a Roth conversion or large gain becomes likely (Source: Rev. Proc. 2025-32; IRS Form 8962).

Frequently asked questions
What is the ACA subsidy cliff in 2026?
The ACA subsidy cliff in 2026 is the hard income ceiling at 400% of the federal poverty line above which premium tax credits fall to zero. A household earning one dollar over the ceiling receives no subsidy at all, unlike 2021 through 2025 when a temporary law removed the cap (Source: 26 U.S.C. 36B(c)(1); CRS Report R48290).
Why did the ACA subsidy cliff come back in 2026?
The cliff returned because the law removing the 400% FPL cap applied only to tax years beginning after Dec. 31, 2020, and before Jan. 1, 2026. It expired on schedule, and the enhanced credits were not extended, so 2026 reverts to the pre-2021 rules with the hard ceiling restored (Source: 26 U.S.C. 36B(c)(1)(E); CRS Report R48290, Dec. 10, 2025).
What is 400% of the federal poverty level for 2026?
Coverage year 2026 uses the 2025 poverty guidelines, based on $15,650 for one person plus $5,500 per additional member. So 400% of FPL is about $62,600 for one person, $84,600 for two, $106,600 for three, and $128,600 for four in the contiguous states. Confirm the exact HHS guideline for your household and state (Source: 26 U.S.C. 36B(c)(1)(A); 2025 HHS Poverty Guidelines).
How do I reduce my MAGI to stay below the ACA cliff?
The rules allow several levers, which are factors to weigh with a professional: deductible HSA contributions (2026 Bronze and catastrophic plans are HSA-eligible), deductible traditional IRA or 401(k) contributions, splitting stock sales across two years, harvesting up to $3,000 of capital losses annually, and spending from Roth or cash savings instead of pre-tax accounts (Source: 26 U.S.C. 36B(d)(2); 1211(b); IRS Notice 2026-5).
Do 401(k) and IRA withdrawals count as income for ACA subsidies?
Yes. Withdrawals from traditional (pre-tax) 401(k) and IRA accounts are taxed as ordinary income, so they raise adjusted gross income and therefore the MAGI used for premium tax credits. Distributions before age 59½ may also carry a 10% additional tax (Source: IRS Pub. 590-B, 2025; IRS Topic No. 558).
Do Roth IRA withdrawals count toward ACA MAGI?
Qualified Roth IRA withdrawals generally do not count toward ACA MAGI, because they are not included in adjusted gross income. That is why Roth and taxable-savings dollars can fund early-retirement spending without pushing a household over the 400% FPL cliff (Source: 26 U.S.C. 36B(d)(2)(B); IRS Pub. 590-B).
Does the ACA subsidy cliff affect people on Medicare?
No. ACA premium tax credits apply to marketplace coverage, not Medicare, and eligibility for subsidies ends when Medicare begins, typically at 65. After 65 a different income test applies: the Medicare IRMAA surcharge, based on MAGI from the tax return filed two years earlier (Source: 26 U.S.C. 36B; 42 U.S.C. 1395r(i)).
How much income can I have and still get ACA subsidies as an early retiree?
For 2026, household MAGI must be at least 100% of FPL and no more than 400% of FPL. That upper limit is about $62,600 for one person and $84,600 for a couple in the contiguous states. In Medicaid-expansion states, adults under 65 below 138% of FPL are generally eligible for Medicaid instead (Source: 26 U.S.C. 36B(c)(1)(A); 42 U.S.C. 1396a(a)(10)(A)(i)(VIII)).
