7 Tax Moves for Early Retirees Before the 2026 ACA Subsidy Cliff Hits
Picture this: a couple in their late 50s, done with the nine-to-five, living off their portfolio. They budgeted carefully. They planned well. Then they pull $82,000 from their IRA instead of $81,760, a difference of $240, and lose every dollar of their health insurance subsidy. Their premiums jump by more than $15,000 for the year. One number, one error, five-figures gone.
That’s the ACA subsidy cliff in 2026, and it’s back with a vengeance. The enhanced premium tax credits that cushioned the blow for the past five years expired at the end of 2025. Congress did not extend them. So the old hard cutoff, earn a dollar above 400% of the federal poverty level and lose every cent of your subsidy, is the law again.
Here’s the piece of good news: it’s only May. Seven months remain in 2026, and your ACA subsidy is calculated on full-year income. That means the moves below can still work. But they only work if you start now, before late-year income you can’t control, dividends, interest, required distributions, fills the bucket for you.
The ACA subsidy cliff returned in 2026: for a two-person household, MAGI above $81,760 eliminates the entire premium tax credit. For a couple in their late 50s, that can mean losing $10,000–$25,000 in annual subsidies. The key is managing Modified Adjusted Gross Income (MAGI), which includes traditional IRA withdrawals, capital gains, dividends, and all Social Security benefits, to stay below the threshold. Seven tactical moves are still available before December 31.
1
Know Your MAGI, It’s Not What Most People Think
Before you can manage the cliff, you need to understand what goes over it. The ACA uses a specific version of Modified Adjusted Gross Income that catches people off guard.
Start with your federal AGI, then add back three things: non-taxable Social Security benefits, tax-exempt interest (yes, your municipal bond interest counts), and untaxed foreign income. That last item almost never applies to retirees, but the first two are landmines.
Traditional IRA withdrawals count dollar-for-dollar. Roth IRA conversions count as income in the year you convert. Capital gains count. Ordinary dividends count. And here’s the one that blindsides people: your full Social Security benefit counts toward MAGI for ACA purposes, even the portion that isn’t taxable for federal income tax purposes. If you’re collecting $24,000 a year in Social Security and none of it is federally taxable, the Marketplace still counts all $24,000.
Run your 2026 MAGI projection now, not in November. Use last year’s tax return as a starting point, add any expected income sources, and find out exactly how far you are from $81,760 (couple) or $60,240 (single).

Spend Roth and Taxable Basis First, Traditional IRA Last
If you have money in multiple account types, traditional IRA or 401(k), Roth IRA, and a taxable brokerage, the order in which you pull income matters enormously when you’re managing an MAGI ceiling.
Qualified Roth IRA distributions are MAGI-invisible. Once your Roth account is at least five years old and you’re over 59½, every dollar you withdraw is tax-free and adds nothing to your MAGI. Same goes for withdrawing the original cost basis from your taxable brokerage, you only realize income on the gain, not the principal. Traditional IRA withdrawals, by contrast, hit your MAGI at full force, dollar for dollar.
The sequencing playbook for a cliff-aware year: cover living expenses from Roth distributions and cost-basis returns first. Only pull from your traditional IRA up to the amount that keeps your MAGI safely below the threshold. Any additional spending comes from Roth or taxable accounts where the tax hit is zero or minimal.
If you’re living on $80,000 a year and you have a meaningful Roth balance, you may be able to fund most of your lifestyle without touching your traditional IRA at all in 2026, keeping MAGI well below the cliff and preserving thousands in subsidies.

Max Out Your HSA to Cut MAGI Directly
If you’re enrolled in a qualifying High-Deductible Health Plan (HDHP) on the ACA Marketplace, you have access to one of the only remaining tools that cuts MAGI dollar-for-dollar: the Health Savings Account deduction.
For 2026, the IRS set HSA contribution limits at $4,400 for self-only coverage and $8,750 for family coverage. If you’re 55 or older and not yet on Medicare, you can add another $1,000 catch-up contribution per eligible spouse. A couple where both spouses are 55+ on a family HDHP can contribute up to $9,750 in total, with each spouse’s $1,000 catch-up going into a separate account per IRS rules.
Even without payroll deductions, you can contribute directly to your HSA and claim the above-the-line deduction on your tax return (reported on Form 8889). You have until April 15, 2027, to make contributions for the 2026 plan year, which gives you a fallback if your income runs higher than expected.
If you’re not currently on an HDHP and you’re near the cliff, compare the math. Sometimes switching to an HDHP to unlock HSA eligibility saves more in subsidies than the higher deductible costs.

For a couple just over the cliff, the math can look like this: $85,000 in MAGI, a $15,000+ annual premium spike — because $85,000 is roughly 402% of the 2025 federal poverty level for a two-person household, which wipes out the entire credit.

Use Tax-Loss Harvesting to Suppress Capital Gains
If you hold investments in a taxable brokerage account, unrealized gains sitting in that account aren’t a problem. Realizing them, selling shares at a profit, creates income that flows straight into MAGI.
Tax-loss harvesting flips this around. When you sell a position at a loss, that loss offsets gains you’ve already realized. The net result is a lower capital gain number on your tax return, and a lower MAGI. For retirees with diversified taxable portfolios, there are almost always some positions sitting at a loss after normal market fluctuation, the discipline is identifying and selling them before December 31.
The rules: losses offset gains of the same type first (short-term against short-term, long-term against long-term), then cross over. Net losses beyond your gains can offset up to $3,000 of ordinary income per year. Unused losses carry forward to future years. And watch the wash-sale rule, if you repurchase substantially identical securities within 30 days before or after the sale, the loss is disallowed.
A $20,000 gain you planned to realize this year, reduced to $8,000 by harvested losses, could be the difference between staying under the cliff and losing your entire subsidy. This is worth a dedicated review mid-year, not a December scramble.

Consider Accelerating Income Into 2025, Or Deferring Into 2027
Income timing is one of the most powerful tools for managing an annual MAGI ceiling. The question isn’t just “how much income do I have” but “when does it hit my tax return.”
If you expect 2026 to be a year where you’re close to the cliff, maybe you have a one-time event like selling a rental property or exercising stock options, it may make sense to defer that income into 2027, when you may have more flexibility or when you’ll already have Medicare coverage. Alternatively, if 2025 was already a high-income year (and the cliff wasn’t relevant because enhanced subsidies still applied), any income you could pull forward into 2025 from 2026 is income that doesn’t count against your 2026 MAGI.
Roth conversion planning is the classic version of this. Converting traditional IRA dollars to Roth creates income in the year of conversion. If 2026 is the year you need to protect your subsidy, don’t convert. If 2027 will be a lower-income year, that’s when larger conversions make sense, and you’ll have Medicare by then, so the ACA cliff won’t apply.
Roth conversions, no matter how smart they are long-term, are MAGI-raising events in the year they happen. Don’t convert anything in a year where you’re near the cliff unless you’ve modeled the full premium impact first.

Track and Update Your APTC Every Quarter, The Repayment Rules Are Brutal Now
This is where things get genuinely dangerous, and it’s worth spelling out clearly. Most people taking ACA subsidies elect to receive them as Advance Premium Tax Credits (APTC), meaning the government pays a chunk of your monthly premium directly to the insurer, and you true it up when you file taxes.
Through 2025, there were caps on how much excess APTC you had to repay if your income ran higher than projected. Those caps are gone. Starting with the 2026 plan year, you must repay every dollar of excess APTC, with no cap and no exceptions. If you estimated $75,000 income, took APTC accordingly, and then your income ended up at $82,000, you owe the full subsidy back when you file in 2027. For a couple, that could mean a five-figure tax bill with no ceiling.
The fix: log into your Marketplace account and update your projected income any time something changes. A part-time consulting engagement, an unexpected dividend, a capital gain, all of it changes your math. The Marketplace adjusts your APTC forward from that point, which limits your year-end exposure. This isn’t a once-a-year conversation. It’s a quarterly check-in, at minimum.
If you’re mid-year and you already know your 2026 income is trending higher than you reported, update your Marketplace application now. The alternative, discovering a $12,000 repayment obligation at tax time in 2027, is far worse.

Think Carefully Before Claiming Social Security Before 65
If you’re in your early-to-mid 60s and haven’t started Social Security yet, here’s a wrinkle most retirement income guides miss: your full Social Security benefit amount, including the non-taxable portion, counts as ACA MAGI.
For a couple where one spouse would collect $28,000 per year in Social Security, starting benefits while both spouses are on the ACA Marketplace could push MAGI up by $28,000, potentially over the cliff. Delaying Social Security past 65 (and taking Medicare at 65 when you no longer need Marketplace coverage) means those benefits don’t count toward your ACA MAGI during the pre-Medicare years at all.
There’s a secondary benefit too: Social Security benefits grow by approximately 8% per year for each year you delay past full retirement age (up to age 70), per the Social Security Administration. So in a cliff-management scenario, deferring Social Security isn’t just a way to preserve your subsidy, it also permanently increases the monthly benefit you eventually collect.
Important caveat: this calculation doesn’t work for everyone. If your health is uncertain, if you need the income, or if the MAGI math works without Social Security, claiming earlier may still make sense. This is one of those decisions that lives at the intersection of health, income needs, and tax planning, precisely the kind of thing worth thinking through with an advisor before you file an application you can’t easily reverse.
For a couple where delaying Social Security keeps both spouses under the cliff for two years before Medicare eligibility, the preserved subsidy could easily exceed $30,000. That’s real money, worth running the numbers before you apply.

Common Questions
What is the ACA subsidy cliff in 2026?
The ACA subsidy cliff is the income threshold above which you lose all premium tax credits for Marketplace health insurance. In 2026, that threshold returned to 400% of the federal poverty level (FPL), because the enhanced subsidies from the American Rescue Plan expired at the end of 2025. For a two-person household, 400% FPL in 2026 is approximately $81,760 in MAGI. Earn one dollar more and you lose the entire credit.
How much can an early retiree lose by going over the cliff?
For a couple in their late 50s, the loss can range from $10,000 to $25,000 per year in premium tax credits, depending on location, age, and the plan they choose. That figure compounds further if insurers raise premiums, median proposed increases for 2026 were around 18%, according to KFF analysis. The hit is highest for older enrollees in high-cost markets.
What counts as income for the ACA subsidy cliff (MAGI)?
ACA MAGI starts with your federal adjusted gross income (AGI) and adds back three things: non-taxable Social Security benefits, tax-exempt interest (such as municipal bond interest), and foreign income. That means traditional IRA withdrawals, capital gains, dividends, part-time income, and the full Social Security benefit amount all count. Municipal bond interest also increases your MAGI even though it isn’t federally taxed. Qualified Roth IRA distributions and withdrawals of cost basis from a taxable brokerage generally do not count.
Do Roth IRA withdrawals count toward ACA MAGI?
Qualified Roth IRA distributions, withdrawals of both contributions and earnings from an account at least five years old, taken after age 59½, do not appear in AGI and are not added back in the ACA MAGI calculation. This makes Roth assets the most MAGI-neutral source of spending money for early retirees managing the subsidy cliff. Roth conversions, however, count as ordinary income in the year of conversion.
What happens if I take too much in advance premium tax credits and then go over the cliff?
Starting with the 2026 plan year, you must repay 100% of any excess advance premium tax credits (APTC) when you file your taxes in 2027. The repayment caps that existed through 2025 are gone. If your income turns out to be above 400% FPL and you received APTC all year, you owe the entire amount back, potentially $10,000 or more for a couple. Update your Marketplace income projection immediately any time your expected income changes.
Rules of thumb only get you so far. The cliff is a bright line, and staying under it requires coordinating Roth withdrawals, capital gain timing, HSA contributions, dividend income, and possibly Social Security decisions, all at once, for a full calendar year. Small errors have large consequences this year.
