Annuity Income and IRMAA

Which annuity payments matter?

The taxable portion of an annuity payment is generally included in AGI. If an annuity is inside a traditional IRA or qualified retirement plan, distributions may be taxable like other retirement-account withdrawals.

Nonqualified annuities may have an exclusion ratio or taxable earnings component. The IRMAA estimate should use the portion that lands in AGI.

Before starting annuity income

• Ask what portion of the payment will be taxable.
• Check whether the annuity sits inside a retirement account.
• Add the taxable amount to pension, Social Security, RMDs, and other income.
• Compare the total with the IRMAA threshold for the relevant premium year.

Qualified versus nonqualified annuities

An annuity inside a traditional IRA or qualified retirement plan is often treated like other pre-tax retirement income when distributions are taxable. A nonqualified annuity may include a tax-free recovery of after-tax investment and a taxable earnings portion. That distinction matters because IRMAA follows the income that lands in AGI.

If you are turning on annuity income near Medicare age, ask for an estimate of the taxable amount that will be reported for the year. Then combine that taxable portion with Roth conversions, IRA withdrawals, pensions, taxable Social Security, capital gains, and tax-exempt interest. Looking at the annuity in isolation can miss the actual Medicare MAGI result.

Why timing can matter

Starting income in December versus January can shift taxable income into a different tax year. That may also shift which Medicare premium year eventually sees the income under the two-year lookback. The answer is not always to delay income, but retirees near a bracket should know which tax year they are filling before they make the election.

Also check whether the annuity payment is flexible or fixed once elected. Some income choices can be adjusted later, while others lock in a payment stream. If the payment will continue every year, the IRMAA question is not only whether one year crosses a threshold. It is whether the new taxable income becomes part of the household's normal Medicare MAGI.
