RMD Strategies: How to Minimize Taxes on Required Minimum Distributions

The RMD Tax Challenge

Required Minimum Distributions are the IRS's mechanism for ensuring that tax-deferred retirement accounts eventually get taxed. Once you reach the applicable age — 73 for those born between 1951 and 1959, and 75 for those born in 1960 or later — you must withdraw a minimum amount from your traditional IRA, 401(k), 403(b), and similar accounts each year. Every dollar withdrawn is taxed as ordinary income.

For retirees with substantial traditional retirement account balances, RMDs can create a significant tax problem. A $1.5 million traditional IRA generates an RMD of approximately $58,000 at age 73. Combined with Social Security income of $30,000 to $40,000, the total pushes taxable income into the 22 or 24 percent bracket — and that is before any other income sources. As the account balance grows (or does not shrink fast enough), RMD percentages increase with age, potentially creating larger tax bills each year.

The challenge compounds. Higher income from RMDs can trigger taxation of Social Security benefits (up to 85 percent may become taxable), increase Medicare premiums through IRMAA surcharges, and push you into higher capital gains tax brackets on investment income. A well-planned RMD strategy addresses not just the direct tax on the distribution but these cascading effects.

Pre-RMD Planning: Roth Conversions

The most powerful RMD strategy begins years before RMDs start. Roth conversions during lower-income years — typically between retirement and the start of RMDs — reduce the traditional account balance subject to RMDs. Every dollar converted to a Roth is a dollar that never generates an RMD.

The math is compelling. If you convert $400,000 from a traditional IRA to a Roth over a 10-year pre-RMD window, paying taxes at 12 to 22 percent, you eliminate approximately $15,000 per year in future RMDs that would have been taxed at 22 to 24 percent or higher. Over a 20-year retirement, that is $300,000 in distributions that will never be taxed — a significant improvement in after-tax retirement income.

The conversion strategy should be calibrated to your specific tax situation. Convert enough each year to fill lower tax brackets without triggering IRMAA surcharges or unnecessary tax bracket jumps. A detailed multi-year projection, ideally prepared with tax planning software or a financial advisor, optimizes the conversion schedule against your projected income, Social Security start date, and RMD schedule.

Qualified Charitable Distributions

If you are charitably inclined, Qualified Charitable Distributions are one of the most tax-efficient strategies available to retirees. A QCD allows individuals aged 70½ and older to transfer up to $105,000 per year (2024 limit, indexed for inflation) directly from their IRA to a qualified charity. The distribution satisfies your RMD requirement, is excluded from taxable income entirely, and counts as a charitable contribution — even if you take the standard deduction.

This is remarkably powerful for retirees who take the standard deduction. Normally, charitable contributions only reduce taxes if you itemize deductions. A QCD provides the equivalent of a charitable deduction even for non-itemizers. On a $10,000 QCD, a retiree in the 22 percent bracket saves $2,200 in federal income tax compared to taking the RMD as income and donating the same amount without itemizing.

QCDs also reduce your adjusted gross income, which can lower Medicare premiums, reduce Social Security taxation, and affect other income-based calculations. If you are already donating to charity from other funds, redirecting those gifts through QCDs from your IRA provides the same charitable outcome with better tax results.

First-Year RMD Timing

Your first RMD can be taken in the year you reach the applicable age or delayed until April 1 of the following year. While the delay seems attractive, it creates a double-RMD year — you must take both your first RMD (for the prior year) and your second RMD (for the current year) in the same calendar year. Two RMDs in one year can push you into a significantly higher tax bracket.

For example, if your annual RMD is $50,000, delaying the first RMD means $100,000 of RMD income in a single year. At the 22 percent bracket, the additional income might push $30,000 or more into the 24 percent bracket — an extra $600 in taxes compared to taking each RMD in its own year. For larger RMDs, the bracket jump can be much more costly.

The general recommendation is to take your first RMD in the year it is due rather than deferring to the following year. The only scenario where deferral makes sense is if your income in the current year is unusually high (making the RMD irrelevant to your bracket) and you expect significantly lower income the following year.

Tax Bracket Management

Strategic RMD planning goes beyond the minimum. If your RMD does not fill your current tax bracket, consider withdrawing more than the minimum — but only if the additional withdrawal serves a purpose. Reasons to withdraw more than your RMD include funding Roth conversions of the excess amount, pre-paying taxes at a lower rate to reduce future RMDs, or harvesting income in a bracket you expect to be lower than future brackets.

Conversely, if your RMD pushes you into a higher bracket, look for ways to offset the income. Charitable contributions through QCDs, capital loss harvesting in taxable accounts, and strategic timing of other income sources can help manage your total taxable income. The goal is to smooth income across years rather than allowing RMDs to create tax spikes.

Coordinate RMDs with Social Security income. If your RMDs are large enough to push combined income above the thresholds for Social Security taxation ($34,000 for individuals, $44,000 for married couples), up to 85 percent of your Social Security benefits become taxable. Pre-RMD Roth conversions that reduce future RMD sizes can keep combined income below these thresholds — effectively making your Social Security benefits tax-free.

Inherited Account Considerations

The SECURE Act of 2019 significantly changed inherited retirement account rules. Most non-spouse beneficiaries must now distribute the entire inherited account within 10 years — and a subsequent IRS ruling clarified that if the original owner had begun RMDs, the beneficiary must take annual distributions within that 10-year window. This accelerated timeline can create substantial tax bills for beneficiaries, especially those in their peak earning years.

This reality strengthens the case for Roth conversions. Inherited Roth IRAs are also subject to the 10-year rule, but the distributions are tax-free. Converting traditional accounts to Roth before death transfers the tax burden from your beneficiaries (who may be in higher brackets) to you (potentially in a lower bracket). For retirees whose primary concern is maximizing the after-tax value of their estate, Roth conversions are among the most effective tools available.

If you are a beneficiary of an inherited retirement account, plan the 10-year distribution strategy carefully. You have flexibility in how much to take each year (subject to any annual RMD requirements). In years when your other income is lower — between jobs, on parental leave, during a career transition — take larger distributions. In higher-income years, take the minimum required. Spreading distributions strategically across the 10-year window can save thousands in taxes compared to lump-sum liquidation or equal annual distributions.
