Required Minimum Distributions: What Changes When You Turn 73

Fact-checked by the Prime Rate editorial team

You’ve spent decades building your retirement nest egg, contributing faithfully to your 401(k), watching it grow, and resisting the urge to dip into it early. Then you turn 73, and the IRS says: “Time’s up. Start withdrawing, whether you need the money or not.” This reality catches millions of retirees off guard, and the penalties for getting it wrong are steep. Understanding required minimum distributions age 73 is no longer optional, it’s a financial survival skill.

The numbers tell a sobering story. According to IRS data, Americans hold over $12 trillion in IRAs alone, all of it subject to RMD rules. The SECURE 2.0 Act of 2022 pushed the RMD starting age from 72 to 73, a change that affects an estimated 4 million Baby Boomers who turn 73 each year through the early 2030s. Miss your distribution deadline, and the IRS imposes an excise tax, reduced from 50% to 25% under SECURE 2.0, but still potentially thousands of dollars per account, per year.

This guide gives you exactly what you need to handle the age-73 RMD transition without overpaying taxes, missing deadlines, or leaving money on the table. You’ll find precise calculation methods, account-by-account rules, tax-planning strategies, and a step-by-step action plan, all grounded in current IRS guidance and backed by expert analysis.

What Changes at Age 73: The New RMD Landscape

Before 2020, the Required Minimum Distribution starting age was 70½, a strange half-birthday that tripped up countless retirees. The SECURE Act of 2019 pushed that to 72. Then SECURE 2.0, signed into law in December 2022, raised it again to 73. Each shift represents a significant change in retirement income planning, and the current rules apply to everyone born between January 1, 1951, and December 31, 1959.

Born in 1951, you hit age 73 in 2024, meaning your RMD clock has already started. Turn 73 in 2025 or 2026, and the rules still apply, but specific deadlines demand attention. The window between 72 and 73 is no longer an RMD year, a relief for some, and a planning opportunity that many miss.

The SECURE 2.0 Timeline at a Glance

The change also affects surviving spouses and beneficiaries, though in more nuanced ways. Inherited IRAs follow the 10-year rule for most non-spouse beneficiaries, a separate and complex set of rules that doesn’t align with the age-73 threshold for original account owners.

Why Congress Keeps Moving the Goalpost

The rationale for raising the RMD age is straightforward: Americans are living longer. Life expectancy has increased dramatically since RMD rules were first codified in the 1970s. Delaying the mandatory withdrawal start gives retirees more years of tax-deferred compounding. It also reflects modern retirement realities, many people work past 70 and don’t need to tap their accounts right away.

For account holders, the practical effect is meaningful. An extra year of tax-deferred growth on a $750,000 IRA earning 6% annually adds roughly $45,000 in additional compounding before the first dollar is touched. That’s not trivial.

How RMDs Are Calculated: The Math Behind Your Withdrawal

The calculation itself is elegantly simple, though the inputs require care. Your RMD amount equals your account balance on December 31 of the prior year, divided by a life expectancy factor from the IRS Publication 590-B Uniform Lifetime Table. The factor decreases each year as you age, which means your percentage withdrawal increases slightly over time.

For a 73-year-old, the distribution period is 26.5. For a 74-year-old, it drops to 25.5. For an 80-year-old, it’s 20.2. These are not negotiable, you must use the IRS-prescribed factors unless your sole beneficiary is a spouse more than 10 years younger, in which case the Joint Life Expectancy Table produces a smaller required withdrawal.

The Calculation in Practice

Notice how the required withdrawal nearly doubles between age 73 and age 90, even with a flat $500,000 balance. In reality, if your account grows faster than you withdraw, the dollar amount you’re forced to take out can escalate significantly, a planning challenge worth addressing early.

Multiple Accounts: Aggregation Rules

Owners of multiple Traditional IRAs must calculate a separate RMD for each account. You can satisfy the total by taking the full amount from any one IRA or a combination. This aggregation rule applies only to IRAs, not to 401(k)s or 403(b)s.

For employer plans like 401(k)s, each plan requires its own separate RMD. You cannot take your 401(k) RMD from an IRA, and vice versa. Violations of this rule are among the most common RMD mistakes, according to IRS data on retirement plan corrections.

Which Accounts Are Subject to RMDs at Age 73

Not every retirement account triggers RMDs at 73. Knowing which accounts are subject to the rules, and which offer an escape hatch, is central to strategic planning. The picture changed meaningfully with SECURE 2.0, particularly for Roth accounts.

Accounts That Require RMDs

The following account types are subject to RMD rules starting at age 73 (for those born 1951–1959):

• Traditional IRAs (including rollover IRAs)
• SEP-IRAs
• SIMPLE IRAs
• 401(k) plans (traditional)
• 403(b) plans
• 457(b) plans (governmental)
• Profit-sharing plans

Each of these accounts received contributions on a pre-tax basis. The IRS has never collected income tax on those dollars, so RMDs are the mechanism to ensure it eventually does. Every distribution is taxed as ordinary income at your current marginal rate.

Accounts Exempt From RMDs

The still-working exception is noteworthy. Still employed at 73 and participating in your current employer’s 401(k)? You can delay RMDs from that specific plan until you actually retire, as long as you own 5% or less of the company. IRAs do not benefit from this exception regardless of your employment status.

The differences between Roth and Traditional accounts are fundamental here. The full comparison of Roth IRA vs. Traditional IRA tax treatment lays out that context clearly and is worth reading before making RMD planning decisions.

RMD Deadlines and the First-Year Decision

Timing matters enormously with RMD deadlines. For most retirees, the annual deadline is December 31 of each year. The first RMD, the one triggered when you turn 73, has a special rule: you can delay it until April 1 of the following year. This is called the Required Beginning Date (RBD).

Turn 73 in 2025, and your first RMD would normally be due by December 31, 2025. You can legally postpone it until April 1, 2026. The catch: your second RMD is still due by December 31, 2026. You’d take two distributions in one calendar year, both fully taxable as ordinary income.

The Double-Distribution Dilemma

Taking two RMDs in one year can be a significant tax burden. An RMD of $20,000 delayed to the following year means $40,000 of ordinary income owed that year. That could push you into a higher marginal bracket, trigger Medicare IRMAA surcharges, or increase the portion of Social Security income subject to tax.

On the other hand, unusually low income in the year you turn 73 might make delaying worthwhile, taking a smaller tax hit that first year before your bracket rises. This is a decision best modeled with a tax professional using your specific income projections.

Setting Up Automatic Distributions

Most IRA custodians and 401(k) administrators allow you to set up automatic annual distributions timed to satisfy your RMD. This is a practical safeguard. Calculate your RMD each year (or let your custodian do it), set the distribution for November or early December, and confirm it was processed before year-end.

Many custodians will calculate and notify you of your RMD amount. But that estimate is only as accurate as the account balance data they hold. Always verify, especially if you’ve made a rollover, conversion, or received a year-end distribution that changed your December 31 balance.

Tax Implications of Required Minimum Distributions Age 73

The tax impact of required minimum distributions age 73 extends well beyond the simple income tax on the withdrawal itself. RMDs can cascade through your entire financial picture, affecting Medicare costs, Social Security taxation, capital gains rates, and estate planning strategies. Ignoring these second-order effects is expensive.

RMD income is classified as ordinary income. It’s reported on Form 1099-R and flows directly to your Form 1040. Unlike qualified dividends or long-term capital gains, there’s no preferential rate. A $50,000 RMD lands on your return at your marginal rate, whether that’s 22%, 24%, or higher.

Social Security Taxation Threshold

Up to 85% of your Social Security income becomes taxable once your combined income exceeds $34,000 (single) or $44,000 (married filing jointly). Combined income includes your adjusted gross income plus half of your Social Security benefits plus any tax-exempt interest. A large RMD can easily push you over these thresholds.

Consider a retiree with $30,000 in Social Security and a $25,000 RMD. Their combined income is approximately $40,000, above the single-filer threshold, meaning a larger share of their Social Security becomes taxable. Managing RMD timing can directly reduce how much of your Social Security you owe tax on.

The interaction between RMDs and Social Security taxation is one of the most underestimated planning challenges retirees face. A $10,000 increase in RMD income can trigger $8,500 in additional taxable Social Security income, effectively creating a marginal tax rate far higher than most people realize. This is well-documented in IRS guidance on combined income thresholds and reinforced by the Social Security Administration’s own income tax guidance for beneficiaries.

IRMAA and Medicare Surcharges

Medicare Part B premiums in 2024 start at $174.70 per month, but they escalate steeply with income. Retirees with modified adjusted gross income above $103,000 (single) or $206,000 (married) face Income-Related Monthly Adjustment Amounts (IRMAA) that can add $1,260 to $4,884 per person annually in Medicare premiums.

A large, unplanned RMD can push you into a higher IRMAA bracket for two years, because Medicare uses income from two years prior. Strategic RMD planning, including Roth conversions before age 73, can keep you below these critical thresholds.

Strategies to Reduce or Manage Your RMDs

The good news: you have more control over your RMD burden than most people realize, especially if you start planning before age 73. Several proven strategies can reduce the size of your RMDs, smooth your tax burden over time, and preserve more wealth for your heirs.

Roth Conversions Before Age 73

The single most powerful long-term RMD reduction strategy is a Roth conversion. By converting traditional IRA dollars to a Roth IRA before your RMDs begin, you reduce the balance subject to mandatory withdrawals. Roth IRAs have no lifetime RMD requirements for the original owner.

The optimal conversion window is typically between ages 60 and 72, after income from work has dropped, but before Social Security and RMDs pile on. Many advisors target filling up lower tax brackets each year through strategic conversions. The comparison of Roth vs. Traditional IRA tax treatment lays out the mechanics clearly.

Qualified Longevity Annuity Contracts (QLACs)

A QLAC is a deferred income annuity purchased within an IRA or 401(k). Under current IRS rules, you can invest up to $200,000 (the limit was raised under SECURE 2.0) from your qualified accounts into a QLAC. That amount is excluded from RMD calculations until the annuity begins paying, which can be deferred until age 85.

This strategy reduces your RMD-eligible balance and provides guaranteed income in your later years. QLACs aren’t right for everyone. Retirees who don’t need the income immediately and want to hedge longevity risk will find them worth serious consideration, but the tradeoff is real: once you purchase a QLAC, that capital is largely illiquid. You give up flexibility in exchange for the tax deferral and income guarantee.

Strategic Spending From Tax-Deferred Accounts Early

Many financial planners recommend drawing down traditional IRA and 401(k) balances in your 60s, even if you don’t need the money for expenses, to reduce future RMDs. Spending from tax-deferred accounts before RMDs kick in prevents your required distributions from growing to unmanageable levels.

This approach works especially well paired with a Roth conversion strategy or a deliberate plan to delay Social Security, keeping income low in early retirement while reducing the RMD pressure that can hit in your mid-70s.

Qualified Charitable Distributions: A Powerful Tax Tool

For charitably inclined retirees, the Qualified Charitable Distribution (QCD) is one of the most tax-efficient tools available. A QCD allows IRA owners aged 70½ or older to transfer up to $105,000 (2024 limit, indexed annually for inflation) directly from their IRA to a qualifying charity, tax-free.

A QCD counts toward your RMD for the year. So instead of taking a taxable distribution and then separately donating cash, the QCD satisfies your RMD obligation while keeping that income off your tax return entirely. The result: lower adjusted gross income, reduced Social Security taxation, and potential avoidance of IRMAA surcharges.

QCD Eligibility Requirements

• You must be at least 70½ at the time of the distribution
• The distribution must go directly from your IRA custodian to the charity, you cannot receive the funds first
• The recipient must be a 501(c)(3) public charity (donor-advised funds and private foundations do not qualify)
• The maximum QCD is $105,000 per person per year in 2024 (married couples can each do up to $105,000 from their own IRAs)
• You cannot also claim a charitable deduction for a QCD, it’s one or the other

The QCD threshold of 70½, not 73, is intentional. You can begin using QCDs before RMDs even start, pre-emptively reducing your IRA balance and limiting future required withdrawals. Even without an immediate tax need, using QCDs for three years before age 73 can meaningfully reduce the RMD burden that follows.

The QCD is arguably the best tax deal in the tax code for charitable retirees, according to Ed Slott and Company. It reduces your AGI dollar for dollar, meaning it benefits you even if you take the standard deduction, which nearly 90% of retirees do.

QCD vs. Standard Charitable Deduction: Which Wins?

The QCD wins decisively for most retirees. Because it reduces AGI, not just taxable income, it has downstream benefits that a standard charitable deduction simply cannot match.

Penalties, Mistakes, and How to Fix Them

Missing an RMD is expensive, but it’s not catastrophic if you act quickly. The RMD penalty under current law (post-SECURE 2.0) is 25% of the amount you failed to withdraw. Historically, this was 50%, one of the stiffest penalties in the tax code. The reduction helps, but 25% of a $20,000 missed RMD is still a $5,000 penalty.

The penalty drops further to 10% if you correct the error within the correction window: the earlier of two years from the year the shortfall occurred, or the date the IRS assesses the penalty. To claim the reduced penalty, you must file IRS Form 5329 and pay the tax on the missed distribution.

Most Common RMD Mistakes

• Forgetting to take an RMD from an old employer 401(k) that was never rolled over
• Using the wrong account balance (must use December 31 of prior year, not current balance)
• Attempting to aggregate 401(k) RMDs across plans (not permitted)
• Rolling over an amount that should have been taken as an RMD (RMDs cannot be rolled over)
• Assuming the custodian automatically calculates and distributes the correct amount without verification
• Overlooking an inherited IRA with its own RMD requirements

The rollover error deserves special attention. Taking an RMD and then attempting to roll it into another IRA within 60 days results in the IRS treating this as an excess contribution, subject to a 6% penalty per year until corrected. RMD amounts are never eligible for rollover, period.

Requesting an IRS Waiver

Prior to SECURE 2.0, taxpayers frequently requested a penalty waiver by attaching a letter to Form 5329 explaining the reasonable cause for the missed RMD. The IRS granted these waivers liberally. Under the current lower penalty structure, waiver requests are still possible, but the reduced base penalty makes them somewhat less critical than before.

To request a waiver, file Form 5329, write “RC” (for Reasonable Cause) next to the penalty line, enter zero as the penalty amount, and attach a brief explanation. Take the missed distribution immediately and report it as income. Most first-time errors are resolved this way without further IRS action.

Required Minimum Distributions Age 73: Long-Term Planning

The real challenge with required minimum distributions age 73 isn’t just the first year, it’s managing them over a potentially 20- to 30-year retirement horizon. As your distribution period shortens each year and your account balances continue growing, RMDs can become an increasingly large share of your taxable income.

Retirees with $1 million or more in tax-deferred accounts face RMDs that can easily exceed $50,000 to $80,000 annually by their early 80s, well above typical spending needs. The excess must be invested in a taxable account, where it generates additional taxable income each year. This compounding tax burden is often called the RMD snowball.

Integrating RMDs Into a Broader Retirement Income Plan

A well-structured retirement income plan coordinates RMDs with Social Security, pension income, investment withdrawals, and spending needs. The goal is to fill lower tax brackets efficiently rather than taking large, unplanned distributions that jump you into higher territory.

For retirees managing multiple income streams, a structured monthly budget framework can help track exactly where each dollar is coming from and ensure RMD income is accounted for in annual tax planning. Similarly, exploring options like CD laddering for non-retirement savings can help manage liquidity without disrupting your RMD strategy.

Estate Planning Considerations

RMDs have direct estate planning implications. Unspent RMDs accumulate in taxable accounts rather than in tax-advantaged retirement accounts, changing the inheritance profile for your heirs. Distributions to heirs from inherited traditional IRAs are taxed as ordinary income, while assets in taxable accounts receive a stepped-up cost basis at death, potentially eliminating capital gains tax entirely.

Spending from taxable accounts first, while letting tax-deferred accounts grow and then satisfying RMDs from those, can improve the overall tax outcome for your estate. Working with an estate attorney and tax advisor to model these scenarios before age 73 is time well spent.

The forced distribution window, from age 73 through your 80s, is actually the last chance to manage your lifetime tax burden and the legacy you leave behind. Retirees who treat RMDs as an obstacle rather than a planning prompt routinely overpay taxes that careful sequencing could have avoided. The analysis from Kitces.com on RMD strategy and income planning documents this point in detail.

For retirees thinking about how their retirement savings interact with contribution rules and account types, reviewing the latest IRA contribution limits and strategies for 2026 provides essential context. And for those looking at how to maximize 401(k) savings while managing RMD exposure, the current 401(k) contribution limits for 2026 are worth understanding in full.

Your Action Plan

1. Determine your exact RMD start date

   Confirm your birth year and identify whether your RMD starting age is 73 or 75 under SECURE 2.0. Born between 1951 and 1959, your first RMD is due in the year you turn 73. Set a calendar reminder for December 31 of that year, or April 1 of the following year if you plan to use the deferral option.

2. Inventory every retirement account you own

   List all traditional IRAs, SEP-IRAs, SIMPLE IRAs, 401(k)s, 403(b)s, and other qualified plans. Note the December 31 balance for each account, that’s the figure used for your RMD calculation. Don’t forget forgotten 401(k)s from former employers; they require their own RMD.

3. Calculate your RMD for each account

   Divide each account’s December 31 balance by the IRS Uniform Lifetime Table factor for your age. For most 73-year-olds, that’s 26.5. Your custodian may provide an estimate, but always verify the math yourself. Your sole beneficiary being a spouse more than 10 years younger qualifies you to use the Joint Life Expectancy Table for a lower required withdrawal.

4. Decide whether to take your first RMD early or defer to April 1

   Model both scenarios with your tax advisor. In most cases, taking the first RMD by December 31 of the year you turn 73 is the better choice, it avoids a double distribution the following year that can spike your tax bill and Medicare costs. Only defer if you have a specific reason, such as an unusually low-income year ahead.

5. Evaluate a Qualified Charitable Distribution if applicable

   Already 70½ or older and charitably inclined? Consider directing part or all of your RMD as a QCD. Set up the distribution directly from your IRA custodian to a qualified 501(c)(3) charity, not through you. This satisfies your RMD and keeps the income off your tax return, protecting your Social Security and Medicare costs.

6. Review your Roth conversion opportunity each year

   Even after RMDs begin, partial Roth conversions may still make sense if you have room in a lower tax bracket. Work with a CPA to determine how much you can convert annually without jumping brackets or triggering IRMAA surcharges. Each dollar converted reduces future RMDs and improves the tax profile of assets left to heirs.

7. Set up automatic distributions with your custodian

   Most IRA custodians and plan administrators allow automatic annual distributions timed to your RMD deadline. Schedule the distribution for November to give yourself a buffer in case of errors or recalculation needs. Confirm the distribution was processed and recorded before December 31.

8. Integrate RMDs into your annual tax planning and budget

   RMDs are taxable income, plan for them accordingly. Adjust your withholding or make quarterly estimated tax payments to cover the additional income. Coordinate your RMD timing with other income sources (Social Security, pensions, capital gains) to minimize the overall tax burden each year.

Frequently Asked Questions

What is the RMD starting age in 2025?

For anyone born between January 1, 1951, and December 31, 1959, the RMD starting age is 73. Turn 73 in 2025, and you must take your first RMD by December 31, 2025, or delay to April 1, 2026, using the first-year deferral option. Born in 1960 or later, your RMD starting age is 75 under SECURE 2.0.

How do I calculate my first required minimum distribution?

Take your IRA or 401(k) balance as of December 31 of the prior year and divide it by the IRS Uniform Lifetime Table life expectancy factor for your age. For a 73-year-old, that factor is 26.5. A $400,000 account balance produces a first-year RMD of $400,000 ÷ 26.5 = $15,094. Recalculate each year using your updated balance and updated age factor.

Can I take more than my RMD?

Yes. The RMD is a minimum, you can always withdraw more. Any amount above the RMD is still taxable as ordinary income (for traditional IRA/401(k) accounts). Excess distributions do not carry over to future years or reduce future RMDs, each year’s RMD is calculated independently. Taking more than required may make sense in low-income years to fill up lower tax brackets.

What happens if I miss my RMD deadline?

The IRS imposes an excise tax of 25% of the amount you failed to withdraw. Under SECURE 2.0, this was reduced from the previous 50% penalty. The penalty drops further to 10% if you correct the shortfall within the two-year correction window by taking the missed distribution and filing IRS Form 5329. Acting quickly is the key to minimizing the penalty.

Are RMDs required from a Roth IRA?

No. Roth IRAs are not subject to RMDs during the original owner’s lifetime. This is one of the key advantages of Roth accounts for long-term tax and estate planning. Starting in 2024, Roth 401(k) accounts are also exempt from lifetime RMDs, thanks to SECURE 2.0. Note that inherited Roth IRAs are subject to the 10-year distribution rule for most non-spouse beneficiaries.

Can I satisfy all my RMDs from one IRA account?

Yes, for IRA accounts only. With multiple traditional IRAs, you can calculate the RMD for each but take the total from any one or combination of those IRAs. This aggregation rule does not apply to 401(k)s or other employer plans. Each 401(k) must have its own RMD taken from that specific plan.

Does a QCD count toward my RMD?

Yes. A Qualified Charitable Distribution satisfies your RMD requirement dollar for dollar, up to the $105,000 annual limit (2024). The amount of the QCD is excluded from your gross income entirely, unlike a regular distribution followed by a charitable contribution deduction. You must be at least 70½ at the time of the distribution, and the payment must go directly from your IRA custodian to the charity.

What if I’m still working at age 73?

Still employed and participating in your current employer’s 401(k)? You can defer RMDs from that plan until you actually retire, provided you own 5% or less of the company. This is called the “still-working exception.” It does not apply to IRAs or old employer 401(k)s, those are subject to RMDs regardless of your employment status.

Can I roll over an RMD into another IRA?

No. RMDs are not eligible for rollover into an IRA, Roth IRA, or employer plan. Attempting to roll over an RMD within 60 days of receiving it causes the IRS to treat the amount as an excess contribution to the receiving account, subject to a 6% annual penalty until removed. The RMD must be taken and treated as taxable income.

How does a QLAC help reduce RMDs?

A Qualified Longevity Annuity Contract lets you move up to $200,000 from your IRA or 401(k) into a deferred income annuity. That amount is excluded from your RMD-eligible balance until the annuity payments begin, which can be deferred until as late as age 85. This reduces your annual RMD during the deferral period while providing guaranteed income in advanced age. The tradeoff: the funds are largely illiquid once committed. QLACs must meet specific IRS requirements and are purchased through insurance companies.

Do RMDs affect my Medicare premiums?

Yes, indirectly. Medicare Part B and Part D premiums are based on your modified adjusted gross income from two years prior. A large RMD, or a double distribution from delaying your first RMD, can push your income above IRMAA thresholds, adding $1,260 to $4,884 per person annually in Medicare surcharges. Planning RMD amounts carefully, particularly in years before age 75, can protect you from premium increases that arrive two years later.

What is the deadline for my very first RMD?

Your first RMD is due by December 31 of the year you turn 73. One exception exists: you can delay the first RMD only, not subsequent ones, until April 1 of the following year. This is the Required Beginning Date. Delaying means taking two full RMDs in the same calendar year, which creates a higher combined tax liability. Most retirees are better served taking the first RMD on schedule.
