What is the ACA subsidy cliff in 2026?

Households above 400% of the federal poverty level get no premium tax credit at all — approximately $63,000 for a single person and $84,000–$85,000 for a couple in the 2026 plan year. One dollar over forfeits the entire credit; verify current thresholds at healthcare.gov.

Do Roth conversions affect ACA subsidies?

Directly — every converted dollar is MAGI in the conversion year. Early retirees often face an explicit trade: convert at low tax brackets or preserve subsidies. Sometimes alternating years (convert big, then stay low) beats doing a little of both.

Does selling my house affect my subsidy?

Only the taxable gain counts — up to $250,000 ($500,000 married) of gain on a primary residence is excluded. Gains beyond the exclusion are MAGI and can eliminate that year's subsidy.

The ACA subsidy cliff is back: income planning for early retirees

By the RetireGlide Team · June 23, 2026

Since the enhanced premium tax credits expired at the end of 2025, ACA subsidy eligibility again ends abruptly at 400% of the federal poverty level — roughly $84,000 of MAGI for a couple (2026 plan year; verify current figures at healthcare.gov). For early retirees in their late 50s and early 60s, whose unsubsidized premiums are the market's highest, one dollar over the line can cost more than $10,000 for the year.

That turns income management — not plan shopping — into the biggest healthcare lever an early retiree has.

Why the cliff hits early retirees hardest

Subsidies cap your premium for a benchmark plan at a percentage of income; the subsidy is the (age-rated) sticker price minus that cap. Because sticker prices for 60-somethings are roughly triple those for young adults, the subsidy being protected is far larger — and so is the cliff. A 62-year-old couple at 395% FPL might pay a few hundred dollars a month; at 405% they pay the full $2,000+/month sticker.

What counts as MAGI (and what doesn't)

ACA MAGI is AGI plus tax-exempt interest, untaxed Social Security, and excluded foreign income. In practice, for early retirees:

Counts: traditional IRA/401(k) withdrawals, Roth conversions, capital gains (including mutual-fund distributions), dividends, interest, rental income, part-time wages.
Doesn't count: Roth IRA withdrawals, spending down cash, selling positions at a loss, the non-gain portion of taxable sales, HSA-qualified withdrawals.
Reduces MAGI: HSA contributions (if on an HSA-eligible plan), deductible IRA contributions from part-time income, capital-loss harvesting.

The planning pattern that works

Successful bridge-year plans typically fund spending from a blend — taxable principal, Roth contributions, and just enough pre-tax withdrawals to stay comfortably under the target threshold — while deferring big Roth conversions and gain realizations to years when they're either below the line or worth blowing through it deliberately. The trade-off is real: every year you suppress income for subsidies is a year you're not converting at low brackets. Which dollar wins depends on your balances and the years remaining to 65 — a genuinely quantitative question worth simulating rather than guessing.

One more wrinkle: subsidy rules have changed three times in five years. Build plans that degrade gracefully if the thresholds move again, and re-check healthcare.gov each fall during open enrollment.
