Your First RMD: The April 1 Trap That Can Double Your Taxable Income

Most people assume the April 1 deadline for their first required minimum distribution is a gift from the IRS. Take your time, defer the payment, ease into retirement income. What it actually does is hand you two fully taxable distributions in a single calendar year, which can push you into a higher bracket, trigger IRMAA surcharges on Medicare premiums, and make your Social Security more taxable all at once.

The Required Beginning Date and the Two-Distribution Problem

Under current law, you must begin RMDs from your traditional IRAs and most employer plans by April 1 of the year following the year you turn 73. That April 1 date is called the required beginning date. The catch: your second RMD is always due by December 31 of that same year. Defer the first one to April, and both land in the same twelve months.

Imagine you turn 73 in 2025. Your first RMD covers the 2025 distribution year. If you wait until April 1, 2026 to take it, you then owe your 2026 RMD by December 31, 2026. Two distributions, one tax return. For many pre-retirees I work with, that single decision quietly adds $30,000 to $60,000 of ordinary income to a year they hadn't budgeted for it.

The cleaner move is almost always to take the first RMD in the calendar year you turn 73, spreading the income across two separate tax years.

Aggregation Rules, Penalties, and What They Actually Mean

Not all accounts follow the same rules. IRAs aggregate: you calculate each IRA's RMD separately but can satisfy the total by withdrawing from any one or combination of your IRA accounts. Employer plans like 401(k)s do not aggregate. Each plan requires its own distribution, taken from that specific account.

If you miss an RMD or fall short, the penalty under current law is 25% of the shortfall. That drops to 10% if you correct the mistake in a timely manner, generally within two years. The IRS also has a history of waiving the penalty entirely when the mistake was reasonable and the distribution is taken promptly. Missing an RMD is fixable. Letting it linger is where it compounds into a real problem.

Pairing Your First RMD with a Qualified Charitable Distribution

If you are charitably inclined and at least 70½, a qualified charitable distribution (QCD) is one of the cleanest tools in the first-RMD conversation. In 2026, you can direct up to $108,000 per person directly from an IRA to a qualified charity. That amount counts toward satisfying your RMD but is excluded from your adjusted gross income entirely.

Here's a real planning scenario I walk clients through: a 73-year-old with a $1.2 million IRA has a first-year RMD of roughly $45,000. She gives $20,000 annually to her church anyway. If she routes that $20,000 as a QCD, her taxable RMD drops to $25,000 and her AGI stays lower, which matters enormously for IRMAA thresholds and bracket management. This is the Harvest stage of a well-built plan, where the sequence and structure of withdrawals does as much work as the portfolio itself. For more on how withdrawal strategy fits a full retirement income framework, see the Sporos Doctrine.

What to Do Before Year-End

If you turn 73 this year, one decision stands out: take the first RMD before December 31 rather than deferring to April. Then look at whether a QCD can absorb part of that distribution before it touches your AGI.

If you want a second set of eyes on how your first RMD interacts with your bracket, Medicare costs, and Social Security taxation, that is exactly the kind of conversation worth having with a fiduciary advisor before the deadline passes.
