Miss your RMD deadline by even one day and the IRS can hit you with a penalty of up to 25% of the amount you should have withdrawn — here’s how to stay ahead of the rules.
Introduction
According to the Federal Reserve’s 2024 Survey of Consumer Finances, more than 60 million Americans hold assets in tax-deferred retirement accounts like 401(k)s and traditional IRAs. That’s great news for long-term savings — but it comes with a legal obligation most people underestimate: Required Minimum Distributions, or RMDs.
If you’ve spent decades building a nest egg inside a tax-deferred account, the IRS eventually wants its share. Once you reach a certain age, the government requires you to start withdrawing a minimum amount each year — whether you need the money or not. Miss the deadline or withdraw too little, and the penalties are steep.
In this guide, you’ll learn exactly what RMDs are, how they’re calculated, what changed under the SECURE 2.0 Act, how to withdraw strategically to reduce your tax bill, and the most common mistakes retirees make. Whether you’re approaching your first RMD or already managing annual withdrawals, this article will help you make smarter decisions with your retirement savings.
What Are Required Minimum Distributions and How Do They Work?
A Required Minimum Distribution is the minimum amount the IRS requires you to withdraw from certain retirement accounts each year once you reach a specific age. The logic is straightforward: the money in your traditional IRA or 401(k) has never been taxed. The IRS deferred taxes when you contributed — but it’s not going to let you defer them forever.
RMDs apply to the following account types:
- Traditional IRAs
- 401(k), 403(b), and 457(b) plans (non-governmental)
- SEP IRAs and SIMPLE IRAs
- Most inherited IRAs (regardless of the beneficiary’s age)
Roth IRAs are the major exception. Because contributions to a Roth IRA are made with after-tax dollars, the IRS does not require you to take RMDs from your own Roth IRA during your lifetime. (Inherited Roth IRAs have different rules.)
Under the SECURE 2.0 Act signed in December 2022, the RMD starting age was pushed to 73 for individuals born between 1951 and 1959, and to 75 for those born in 1960 or later. If you turned 73 before 2023, you were already subject to the previous rules. This is one of the most impactful retirement law changes in decades, giving millions of Americans more time to let their savings grow.
Your first RMD can be delayed until April 1 of the year following the year you turn 73 (or 75, depending on your birth year). After that, all subsequent RMDs must be taken by December 31 of each calendar year. Be aware: if you delay your first RMD to April 1, you’ll be required to take two RMDs in that same year, which could push you into a higher tax bracket.
How Is Your RMD Amount Calculated?
The IRS uses a specific formula to calculate your annual RMD. According to IRS Publication 590-B, the calculation is:
RMD = Account Balance ÷ Distribution Period (Life Expectancy Factor)
The account balance used is the value of your retirement account as of December 31 of the previous year. The life expectancy factor comes from the IRS Uniform Lifetime Table — a set of divisors that decrease each year as you age, resulting in gradually larger RMD percentages over time.
Here’s a simplified example:
- Your traditional IRA balance on December 31, 2025: $500,000
- Your age in 2026: 73
- IRS life expectancy factor at age 73: 26.5
- Your 2026 RMD: $500,000 ÷ 26.5 = $18,868
As you get older, that divisor shrinks, meaning a larger percentage of your balance must be withdrawn each year. At age 80, for instance, the factor drops to 20.2. At age 90, it falls to 12.2.
If you have multiple traditional IRAs, you can calculate the RMD for each separately but take the combined total from any one (or a combination) of those accounts. However, if you have multiple 401(k) plans, you must take each plan’s RMD separately from that specific plan — they cannot be aggregated the way IRAs can.
The IRS provides worksheets and tables in Publication 590-B, and most major custodians like Fidelity and Vanguard will calculate your RMD for you — though the responsibility for accuracy and timing always falls on you.
Key Strategies to Minimize the Tax Impact of RMDs
RMDs are counted as ordinary income, which means they can push you into a higher tax bracket, trigger higher Medicare premiums (via IRMAA surcharges), increase taxes on your Social Security benefits, and reduce eligibility for certain deductions. The good news: there are legal strategies to reduce your RMD tax burden significantly.
1. Roth Conversions Before RMDs Begin
One of the most effective strategies is converting a portion of your traditional IRA to a Roth IRA in the years before your RMDs start. Since Roth IRAs are not subject to RMDs, this reduces the balance that will be subject to mandatory withdrawals — and future growth in the Roth account is tax-free.
For example, if you retire at 65 and RMDs start at 73, you have an 8-year window to do partial Roth conversions. The goal is to convert enough each year to fill up your current tax bracket without jumping into the next one. This requires careful tax planning, ideally with a CPA.
2. Qualified Charitable Distributions (QCDs)
If you’re charitably inclined and age 70½ or older, a Qualified Charitable Distribution (QCD) lets you transfer up to $105,000 per year (2026 inflation-adjusted limit) directly from your IRA to a qualified charity. That amount counts toward your RMD but is excluded from your taxable income — a powerful combination.
This strategy is especially valuable for retirees who take the standard deduction and wouldn’t otherwise benefit from charitable deductions. It effectively makes your charitable giving tax-free.
3. Withdraw Strategically Throughout the Year
Rather than taking your entire RMD in December, consider spacing withdrawals throughout the year. This gives your account more time invested, can help with cash flow planning, and may reduce the risk of a year-end market dip affecting your withdrawal amount.
4. Coordinate RMDs with Social Security and Other Income
If you’re receiving Social Security benefits, up to 85% of your benefits can become taxable depending on your combined income — and RMDs count toward that calculation. A financial advisor can help you sequence withdrawals from different accounts to minimize the percentage of Social Security that gets taxed. You can learn more about timing Social Security optimally at Social Security Optimization: When and How to Claim.
Costs, Fees, Penalties, and Risks to Understand
The IRS does not take missed RMDs lightly. Under the SECURE 2.0 Act, the penalty for failing to take an RMD was reduced from 50% to 25% of the amount that should have been withdrawn — and drops further to 10% if you correct the mistake within two years. Still, that’s a painful penalty that can be entirely avoided with proper planning.
Beyond penalties, consider these risks:
- Tax bracket creep: Large RMDs combined with Social Security, pension income, or part-time work can push you into a higher federal bracket unexpectedly.
- IRMAA surcharges: Medicare Part B and Part D premiums increase at higher income levels. In 2026, IRMAA thresholds start at $106,000 (single) and $212,000 (married filing jointly). A large RMD can trigger significantly higher premiums.
- State income taxes: Most states tax RMDs as ordinary income, though some states like Florida, Texas, and Nevada have no state income tax — a factor worth considering in retirement location planning.
- Account depletion risk: If your RMDs are larger than expected due to strong market gains, you may be withdrawing more than you intended to spend — raising questions about reinvestment strategy.
Common RMD Mistakes to Avoid
Even financially savvy retirees make costly RMD errors. Here are the five most common — and how to avoid them:
Mistake 1: Missing the Deadline
Every year, the RMD deadline is December 31 (with the exception of your very first RMD, which can be delayed to April 1 of the following year). Set a calendar reminder in October to review your RMD and ensure the withdrawal is processed in time — custodians can have processing delays.
Mistake 2: Taking Only One RMD When You Have Multiple Plans
Remember: if you have multiple 401(k) accounts from different employers, each plan requires its own separate RMD withdrawal. You can’t aggregate them the way you can with IRAs. Many retirees mistakenly consolidate the calculation and miss a plan entirely.
Mistake 3: Forgetting Inherited IRAs
The SECURE Act of 2019 eliminated the "stretch IRA" strategy for most non-spouse beneficiaries, requiring them to fully distribute inherited IRA assets within 10 years. In 2024, the IRS finalized rules requiring annual RMDs within that 10-year window in certain cases. If you inherited an IRA, don’t assume you can wait until year 10 to take everything — consult a tax professional to understand your specific situation.
Mistake 4: Not Withholding Taxes from Your RMD
RMDs are taxable income, but unlike a paycheck, taxes aren’t automatically withheld unless you request it. You can elect to have federal (and state) taxes withheld directly from your RMD distribution. Failing to do so can result in a surprise tax bill — and potentially underpayment penalties — at tax time.
Mistake 5: Ignoring the First-Year Double RMD Trap
If you delay your first RMD to April 1 of the year after you turn 73, you’ll also owe a second RMD for that same calendar year by December 31. Taking two full RMDs in one year can significantly increase your taxable income. In many cases, it’s smarter to take your first RMD in the actual year you turn 73 to spread the tax impact.
Alternatives and Complementary Strategies to Consider
RMDs are mandatory for certain accounts — but smart retirement planning involves a mix of account types that give you more flexibility.
Roth IRA
Contributing to or converting to a Roth IRA earlier in your career or during low-income retirement years means that money grows tax-free and has no RMDs during your lifetime. This is one of the most valuable tools for managing retirement tax exposure. If you haven’t already explored the Roth IRA vs. Traditional IRA comparison, it’s worth reviewing before making conversion decisions.
Health Savings Account (HSA)
An HSA is the only account that’s triple tax-advantaged: contributions are tax-deductible, growth is tax-free, and withdrawals for qualified medical expenses are tax-free. Unlike IRAs, HSAs have no RMDs. If you’re still eligible (enrolled in a high-deductible health plan), maxing out your HSA and letting it grow for medical expenses in retirement is a powerful complement to your RMD planning. This can be especially powerful when paired with a solid Medicare strategy.
403(b) and 457(b) Plans
If you work in education, healthcare, or government, your retirement plan may have unique RMD rules or rollover options. For instance, 457(b) plans for government employees allow penalty-free withdrawals at any age upon separation from service — giving you more flexibility before RMDs kick in.

Frequently Asked Questions About RMDs
Q: What happens if I don’t need the RMD money — can I reinvest it?
Yes. Once you’ve taken the required distribution and paid taxes on it, you can reinvest the after-tax amount in a taxable brokerage account. You cannot put it back into a tax-deferred retirement account (unless you’re still working and eligible to contribute to a 401k or IRA), but investing in a regular brokerage account continues to grow your wealth.
Q: Do I have to take an RMD the year I turn 73 if I’m still working?
If you’re still actively employed and participating in your current employer’s 401(k) plan, you may be able to delay RMDs from that specific plan (not from old 401(k)s or IRAs) until you retire — as long as you don’t own more than 5% of the company. This is sometimes called the "still-working exception."
Q: Are RMDs eligible for rollover to another retirement account?
No. RMDs are not eligible for rollover. You cannot transfer your RMD to another IRA or 401(k) to defer taxes. The withdrawal must be taken as a distribution, and taxes are due for that year. This is a common point of confusion, especially for retirees who are used to rolling over accounts.
Q: Can my RMD amount change from year to year?
Yes, your RMD changes every year based on two variables: your account balance on December 31 of the prior year and your updated life expectancy factor from the IRS table. A strong year in the market will increase your account balance and therefore your RMD. A down year will reduce it. That’s why annual RMD recalculation is essential.
Q: What if my spouse is my sole beneficiary and is much younger than me?
Good news: if your sole IRA beneficiary is a spouse who is more than 10 years younger than you, you can use the IRS Joint Life and Last Survivor Expectancy Table instead of the standard Uniform Lifetime Table. This gives you a larger divisor, which means a smaller required withdrawal — and lower taxes each year.
Final Takeaways: Plan Ahead, Not After the Fact
Required Minimum Distributions are one of the most predictable aspects of retirement — the rules are set, the timelines are fixed, and the penalties for non-compliance are clearly defined. That predictability is actually an advantage: it means you can plan around RMDs years in advance.
Start by knowing your starting age under current law (73 or 75, depending on your birth year), understanding which accounts are subject to RMDs, and calculating your projected RMD amounts in retirement. Then layer in strategies like Roth conversions during low-income years, QCDs if you’re charitably minded, and careful coordination with Social Security income to keep your tax bill as low as legally possible.
The biggest mistake most retirees make is waiting until they’re 72 or 73 to think about RMDs. The best outcomes come from planning in your 50s and 60s, when you still have time to reposition assets. Talk to a licensed financial advisor or CPA to build a withdrawal strategy tailored to your income, tax bracket, and retirement goals.
