Retired Couple Collects $138,000 a Year Without IRMAA as Medicare Threshold Starts at $218,000

Q: Why might earning just one extra dollar in retirement cost you thousands in unexpected healthcare surcharges?

Because Medicare’s IRMAA works like a cliff, not a gradual phase-in. If your modified adjusted gross income goes just $1 above a threshold, you can be pushed into a higher bracket and owe the full surcharge for the entire year on both Part B and Part D premiums. For 2026, the first IRMAA threshold is $218,000 for married couples filing jointly and $109,000 for single filers, based on 2024 tax returns. A couple at exactly $218,000 stays at the standard Part B premium of $202.90 a month per person. At $218,001, each spouse moves to $284.10 a month for Part B, plus a Part D surcharge of $14.50 a month. That one extra dollar can cost a Medicare couple roughly $2,300 more over the year. The surprise is that IRMAA is based on MAGI, not how much cash you actually spend in retirement. Traditional IRA and 401(k) withdrawals, RMDs, capital gains, taxable Social Security, dividends, interest, and even tax-exempt municipal bond interest can count. Roth IRA withdrawals generally do not, and qualified charitable distributions can help keep IRA money out of MAGI. The other trap is timing. Medicare uses a two-year lookback, so a one-time income spike in 2024, such as a Roth conversion, property sale, or large investment gain, can raise premiums in 2026 even if your income is lower by then. That is why retirees near an IRMAA cutoff often manage withdrawals, gains, and charitable transfers very carefully.

$138,000 in annual retirement cash flow can stay below Medicare's 2026 IRMAA trigger because the surcharge is based on modified adjusted gross income, not total cash received.
$218,000 is the joint-filer threshold; go over by $1 and a couple pays the full next Part B and Part D surcharge step, with no phase-in beyond the roughly $203 standard Part B premium.
Roth IRA withdrawals, REIT return of capital, basis withdrawals from taxable accounts and qualified dividends can all help keep MAGI lower than spendable income.
$3.94 million at a 3.5% yield, $2.3 million at 6%, or $1.38 million at 10% would generate $138,000 a year, though higher-yield strategies often carry greater principal-erosion risk.
A 2-year lookback means 2026 IRMAA is set from 2024 tax returns, while Social Security's projected 3.1% 2027 COLA could further narrow the income buffer.
