The 7 Rmd Tax Traps Waiting For You In Your 70s — And How To Start Disarming Them In Your 60s

For decades, you've saved in tax-deferred retirement accounts, watching your balance compound untaxed. Then you turn 73, and the IRS comes calling.

Required minimum distributions (RMDs) force you to begin withdrawing and paying taxes on those savings — whether you need the money or not.

What many retirees don't realize until it's too late is that RMDs don't just create a tax bill. They trigger a cascade of consequences that can raise Medicare premiums, subject Social Security to taxation, push you into higher brackets and affect your estate planning.

Understanding these traps before your first RMD can save you thousands over your retirement.

1. The Medicare premium surcharge trap

One of the most common surprises hits retirees in their monthly Medicare bills. Part B and Part D premiums are income-based, with higher earners paying more through income-related monthly adjustment amounts (IRMAAs).

The trap: IRMAA is based on your modified adjusted gross income (MAGI) from two years prior, so a large RMD in 2025 raises your premiums in 2027.

For 2026, surcharges begin at $218,000 for joint filers. At the highest tier, Part B premiums reach $689.90 per month per person, versus the standard $202.90.

A $1 million account generates an RMD of roughly $37,736 at age 73. If that pushes you just over an IRMAA threshold, you could pay an extra $2,000 to $5,000 a year in premiums — money that never shows up on your tax return but flows directly from your RMD.

2. The Social Security taxation trap

Up to 85% of your Social Security benefits can become taxable depending on your combined income (adjusted gross income, tax-exempt interest and half of your benefits). The thresholds are surprisingly low: $32,000 for joint filers and $25,000 for single filers.

Large RMDs push many retirees over these thresholds, turning tax-free Social Security income into taxable income. Consider a couple with $40,000 in Social Security and $30,000 in pension income.

Without RMDs, they might owe minimal tax, but add a $50,000 RMD and suddenly $34,000 of their Social Security becomes taxable (85% of $40,000), sharply raising their bill.

The math gets worse because the effect is marginal. In the phase-in range, every additional dollar of income makes 85 cents of Social Security taxable.

3. The tax bracket cascade

RMDs don't just add to your taxable income — they can push you into higher tax brackets, where each additional dollar is taxed at a higher rate. The 2026 federal brackets create several danger zones where modest RMDs trigger significant tax increases.

For married couples filing jointly, the jump from the 12% to 22% bracket occurs at $100,800 of taxable income. The next jump to 24% happens at $211,400. These thresholds are inflation-adjusted annually, but RMD amounts grow faster as you age and your life expectancy decreases on the IRS tables.

The hidden trap: Many retirees assume they'll be in a lower bracket in retirement. But combine RMDs with Social Security, pensions and perhaps part-time or investment income, and your marginal rate can exceed what it was in your working years.

4. The net investment income tax trap

Once your MAGI exceeds $250,000 (joint) or $200,000 (single), you face the 3.8% net investment income tax (NIIT) on interest, dividends and capital gains.

The indirect trap: RMDs don't count as net investment income themselves, but they raise your MAGI. If that pushes you over the NIIT threshold, your investment income becomes subject to the extra 3.8% tax.

For retirees with substantial taxable accounts, this can add thousands to the annual bill.

5. The charitable deduction trap

Many retirees donate to charity and assume they can deduct it. But the 2017 Tax Cuts and Jobs Act nearly doubled the standard deduction to $31,500 for joint filers in 2025, making itemizing unnecessary for most households.

The trap: if you take the standard deduction, your charitable contributions provide zero tax benefit, while your RMD increases your taxable income. The solution is a qualified charitable distribution (QCD), but many retirees don't learn about it until after they've already taken their RMD and made separate gifts, missing the chance to lower their taxable income.

QCDs let retirees 70½ and older transfer up to $111,000 annually, directly from an IRA to charity. The distribution counts toward your RMD but doesn't appear in taxable income, effectively making your giving tax-deductible even if you take the standard deduction.

6. The state tax trap

While the federal consequences of RMDs are widely discussed, state treatment varies dramatically. Some states fully exempt retirement distributions, others tax them at ordinary income rates, and a few have special provisions.

In high-tax states, RMDs can trigger substantial bills. California's top rate is 12.3% (plus a 1% surcharge over $1 million), and New York's reaches 10.9%. A $100,000 RMD could generate $10,000 or more in state taxes alone.

The trap: Retirees who move to low- or no-income-tax states, such as Florida, Texas and Nevada, can avoid this. Those who delay the move may pay substantial state taxes on RMDs for years.

7. The widow's penalty

When one spouse dies, the survivor faces a particularly painful RMD trap. Joint filers enjoy wider brackets and higher standard deductions than single filers. After the year of death, the survivor must file as single, with brackets roughly half the width of joint ones.

Yet the RMD continues at nearly the same level, based on the account balance and the survivor's age, not filing status. This combination often pushes widows and widowers into significantly higher brackets, a phenomenon planners call the "widow's penalty."

How to minimize RMD tax traps

While you can't avoid RMDs entirely once you reach the required age, several strategies can reduce their tax impact.

Roth conversions before RMDs begin. Converting traditional IRA funds to Roth IRAs in your 60s and early 70s lets you control the timing and amount of taxable income. Roth IRAs have no RMDs during the owner's lifetime, and qualified withdrawals are tax-free.

Strategic timing of other income. Delay Social Security or spread capital gains across multiple years to create lower-income years for Roth conversions or to minimize the impact of early RMDs.

Qualified charitable distributions. Use QCDs to satisfy RMD requirements while reducing taxable income if you're charitably inclined.

Asset location planning. Keep tax-efficient investments (index funds, municipal bonds) in taxable accounts and high-income holdings (REITs, bonds) in Roth accounts where possible.

The key is planning ahead. By the time you face your first RMD, many of the most effective strategies are off the table. Working with a financial adviser in your 60s to model scenarios can help you avoid these hidden traps before they cost you.
