The first required minimum distribution comes with a one-time April 1 extension, but using it does not move the next December 31 deadline. That overlap can place two withdrawals into one tax return and concentrate income that would otherwise have been split across years. The extension is therefore not extra deferral in the long run; it is a timing election that can change tax brackets, Medicare premiums and the taxation of Social Security benefits.

The April option applies only to the opening distribution
The IRS RMD guidance generally requires a first distribution for the year an account owner reaches age 73, while allowing payment as late as April 1 of the following year. Each later distribution remains due by December 31 of its own year. The two deadlines coexist; the first does not push the second into a later calendar.
An owner who takes the opening distribution by December 31 keeps the first and second RMDs in separate tax years. Waiting until the following March places the delayed first payment and the new year’s payment between January and December of that same year. Each amount is calculated for its own distribution year using the relevant prior-year balance and life-expectancy factor.
The rule is not identical for every workplace participant. A non-owner in an employer plan may be able to delay RMDs until retirement if the plan permits, while a 5% owner generally cannot use that still-working exception. Traditional IRAs use the age-based starting rule regardless of continued employment. Employment with a different company does not generally postpone the old employer plan’s deadline under the current-employer exception.
Two distributions can amplify other income-based costs
RMDs from pretax accounts generally enter ordinary taxable income. IRS Publication 575 explains that after the starting year, annual minimums continue on the December schedule and that two payments result when the first is deferred. After-tax basis and qualified Roth amounts can alter taxation, but most traditional account balances produce taxable distributions.
Combining two payments can push part of income into a higher federal bracket, increase the portion of Social Security subject to tax or reduce income-tested deductions and credits. The distribution also enters the modified adjusted gross income used two years later for Medicare income-related premium adjustments. A timing choice made at 73 can therefore reappear in health premiums at 75. State income-tax treatment can add another timing effect because retirement-income exclusions vary by jurisdiction.
Deferral can still be rational when the first year contains unusually high wages, a business sale or another temporary income spike. Moving the RMD into a quieter year may save more than the second distribution adds. The comparison is between two complete tax years, not between taking money now and avoiding it entirely. Estimated-tax and withholding requirements can also shift when both distributions land in the later year.
The account balance keeps moving while the deadline shifts
An RMD is generally calculated by dividing the prior December 31 balance by the applicable life-expectancy factor. The delayed first distribution uses one balance date, while the second uses the next. Market movement and prior withdrawals can make the two required amounts materially different even though they are paid in the same calendar year. A spouse more than ten years younger can also change the applicable IRS life-expectancy table.
Taking more than one year’s minimum does not prepay a future RMD. IRS Publication 590-B treats each year as a separate obligation, and excess withdrawals cannot be carried forward to satisfy the next one. That annual separation is why the April extension creates two distinct payments rather than one enlarged distribution credited across years.
The extension’s value lies entirely in where income lands. It can shift a first distribution away from a high-income year, but it cannot eliminate that distribution or postpone the second. The stronger decision compares marginal tax effects, Medicare consequences and the two account balances before choosing which calendar year should carry the opening RMD. Federal withholding can be elected on distributions, but it does not change the amount required to leave the account.
