Your Annuity Paid Out. Medicare Thinks You're Rich. Here's What's Actually Happening.

You buy an annuity for one reason: to lock in a stream of income that doesn't stop when the market does. You fund it with $50,000. Years later, it pays out a much larger sum. Your cash-flow engine is working exactly as designed.

Then Medicare sends you a notice saying your premiums are going up — because your income two years ago put you over a threshold. The headlines love to scream about stories like this: a retiree caught off guard by a Medicare surcharge triggered by an annuity payout. The drama is real. But the mechanics behind the surprise are far less ominous than the headlines suggest.

Let's look at what's actually producing the income, what Medicare is actually counting, and whether the damage is permanent or just a timing mismatch you can fix.

What Medicare Is Counting

Medicare doesn't look at your bank balance. It doesn't look at your cash flow. It looks at your tax return from two years ago and uses a measure called Modified Adjusted Gross Income, or MAGI. MAGI is your Adjusted Gross Income from line 11 of Form 1040, plus any tax-exempt interest.

That two-year lag is the root of most IRMAA (Income-Related Monthly Adjustment Amount) surprises. You received a large annuity distribution in 2024. In 2026, Medicare reviews that 2024 tax return and adjusts your premiums accordingly. By the time you get the notice, the income event is already in the rearview mirror. The surcharge feels like a punishment for a decision you can no longer change.

For 2026, the first IRMAA threshold kicks in at $109,000 in MAGI for individuals, or $218,000 for married couples filing jointly. Cross that line by a single dollar and the surcharge applies to the entire year — not prorated, not partial. There are five tiers above the base, pushing Part B premiums from the standard $202.90 per month all the way up to $689.90 at the highest bracket. Part D surcharges stack on top.

Here's What the Headlines Get Wrong

The sensational stories imply that the entire annuity payout — including your own principal — is being counted as income. That's not how it works for non-qualified annuities, which are the ones most retirees buy with after-tax dollars.

When a non-qualified annuity is set up to pay you a guaranteed monthly income for life, the IRS applies what's called an exclusion ratio. Each payment is split into two parts: a tax-free return of your original principal investment, and a taxable portion representing the earnings the annuity generated over time. The taxable portion is what flows into your AGI, and ultimately into MAGI. The tax-free principal return does not.

For example, if you paid $100,000 into an immediate annuity and it's paying $565 per month with an expected return of $135,600 over your life expectancy, roughly 74% of each payment is a tax-free return of principal. Only the remaining $148 or so per month counts as taxable income.

If instead you took a lump-sum surrender from a non-qualified annuity, the IRS applies a Last-In, First-Out rule. The earnings come out first and are fully taxable. Only after all the accumulated gains are withdrawn does the principal start coming back tax-free. This means a large lump-sum distribution early in the annuity's life could be mostly taxable, since the IRS treats the first dollars out as untaxed earnings.

If the annuity was purchased inside a qualified account like a Traditional IRA or 401(k), the entire distribution is taxable — because your original contributions were made with pre-tax dollars. That's the scenario where a large payout really does spike MAGI by its full amount.

The Income Stream Is Still Sound

Here's the question that matters first: is the annuity still paying? If it is, the cash-flow engine is intact. The IRMAA surcharge doesn't affect your annuity income, your coverage, or your underlying assets. It affects only the premium you pay for Medicare Part B and Part D.

And the surcharge is not necessarily permanent. IRMAA is recalculated every year based on the most recent tax return the IRS has provided. If your income drops in the following year, the surcharge automatically decreases two years later. A one-time distribution spike does not mean you're locked into higher premiums forever.

There's also an escape hatch. If your current income has genuinely declined since the tax year Medicare is using — retirement, divorce, death of a spouse, loss of income, or cessation of work qualify — you can file Form SSA-44 to request a redetermination. Social Security will review your case and can adjust your premiums based on your current income rather than the two-year-old tax return. You have 60 days from the date of the IRMAA notice to file.

This appeals process is designed precisely for situations like the one the headlines dramatize: a one-time income event that doesn't reflect your actual financial picture.

What You Can Actually Control

The annuity payout timing is often locked in once the income stream starts. But how that income is structured can matter enormously for Medicare premiums.

Income blending is the practical tool here. If you have access to Roth IRAs (qualified withdrawals don't count toward MAGI), taxable accounts, and traditional accounts, you can balance withdrawals to keep your MAGI below the IRMAA thresholds. For annuity holders specifically, understanding whether your contract uses an exclusion ratio or LIFO taxation determines how much of each payment shows up as taxable income.

Qualified Charitable Distributions — if you're 70½ or older — let you direct IRA distributions straight to charity without counting them as income. This keeps MAGI down without sacrificing the withdrawal.

The two-year lookback also means you can plan ahead. If you know you're approaching an IRMAA threshold, timing large distributions, Roth conversions, or asset sales around the calendar can prevent an unintended premium jump two years down the road.

The Portfolio Role

An annuity's job in a retirement portfolio is to create income you can't accidentally sell. Stocks can gap down on bad news. Bond funds can lose principal when rates spike. An annuity that pays a guaranteed amount does what it says. That reliability is the product you bought, and IRMAA doesn't change it.

What the Medicare surcharge does change is the net cash flow. At the highest IRMAA bracket, you're paying roughly $487 more per month in Part B premiums and another $91 for Part D — nearly $7,000 a year in additional premiums. That's real money, and it deserves respect. But it's a surcharge on healthcare premiums, not a tax on your annuity, and it's not permanent.

The income-first discipline here is simple: if the annuity is still paying, the cash-flow engine is working. If the IRMAA notice is based on a one-time income spike that doesn't reflect your current financial reality, file the SSA-44. If you're going to face the surcharge, treat it as a known cost of healthcare and plan around it rather than letting it derail the income architecture you built.

We're here first as human beings trying to fund a comfortable retirement without forcing sales at the wrong time. An annuity payout is supposed to help you do that. A Medicare surcharge based on income from two years ago is an administrative friction point, not a reason to rethink a strategy that's doing its job.
