RMD Timeline Analysis
Based on your 1954 birth year, you turn 73 in 2027 — that is the year your Required Minimum Distributions must begin. You have 1 years before the first one is due. Use that window for Roth conversions and tax planning: once RMDs start, they are taxed as ordinary income and are no longer optional.
*Applies the SECURE 2.0 Act Required Minimum Distribution ages and IRS life-expectancy framework. The still-working exception generally requires owning less than 5% of the employer, applies only to the current employer's plan (not IRAs or prior employers), and must be permitted by the plan. The 25% excise penalty (reducible to 10% if corrected within two years) applies to missed RMDs. Consult a tax professional.
When Do Required Minimum Distributions Begin?
Once you build a traditional 401(k), IRA, or other pre-tax retirement account, the IRS eventually requires you to start withdrawing from it — and the timing is set by your birth year. These are Required Minimum Distributions (RMDs): the smallest amount you must take out each year so the deferred tax on that money finally gets collected. The single most important question for every account holder past mid-career is simple — in what year must my first RMD be taken? Get it wrong, or miss the date, and the IRS imposes one of the harshest penalties in the entire tax code. The SECURE 2.0 Act of 2022 rewrote the rules. People born in 1950 or earlier reach RMD age at 72. Those born from 1951 through 1959 reach it at 73. And anyone born in 1960 or later waits until 75. Because the age depends on birth year, two 72-year-olds can have very different deadlines. This tool answers the timing question precisely and pairs it with the still-working exception, so you can see not just when your first RMD is due but how much planning runway you have before withdrawals — and their tax bill — become mandatory.
Birth Year to First RMD Year
The calculation maps your birth year to an RMD starting age using the SECURE 2.0 schedule, then adds that age to your birth year to produce the first tax year an RMD is required. Birth year 1950 or earlier gives age 72; 1951-1959 gives age 73; 1960 or later gives age 75. Your first RMD is due for the year you reach that age, and while the very first distribution can be delayed until April 1 of the following year, doing so forces two distributions — and two tax bills — into a single calendar year, which can push you into a higher bracket. A special rule helps people who keep working. If you are still employed by the company sponsoring your current 401(k) and you own less than 5% of it, that plan may allow you to defer RMDs from that specific account until you actually retire. But the exception never applies to IRAs or to accounts from prior employers, and it must be written into the plan. This calculator flags the exception when you toggle the still-working option. The tool also surfaces the 25% excise penalty on any missed amount, reduced to 10% if corrected within two years, to underline why the exact start year matters.
Expert Insights
The Years Before Your First RMD Are a Golden Planning Window
The gap between retirement and your first RMD is the most valuable tax-planning stretch most retirees will ever have. Use it to run Roth conversions, harvest capital gains within lower brackets, and strategically withdraw from taxable accounts first. Every dollar converted to Roth before RMDs start is a dollar that never triggers a forced taxable withdrawal later.
Missing an RMD Is Exceptionally Expensive
The excise tax on a missed RMD is 25% of the shortfall — one of the largest penalties in the tax code. If you discover the mistake and correct it by filing an amended return and taking the distribution within two years, the penalty drops to 10%, but there is no excuse provision that removes it entirely. Set calendar reminders and confirm with your custodian each December whether the RMD was actually processed.
Your First RMD Has a Deadline Trap
The first RMD can be deferred to April 1 of the year after you reach RMD age, but that's a required beginning date, not a free pass. If you defer, you take two RMDs in that second calendar year, which can double the taxable income and push you over Medicare IRMAA surcharge thresholds or into a higher bracket. Many retirees deliberately take the first RMD in the year they reach RMD age to spread the tax.
Actionable Tips
- 1
Map Every Account to Its Own RMD Rules
RMDs from multiple IRAs generally aggregate — you can take the total from one IRA — but 401(k) RMDs are calculated separately per employer plan. Identify each account type and whether the still-working exception applies before projecting a single deadline. This tool gives the starting year; pair it with the full RMD calculator for the dollar amount.
- 2
Use the Runway for Roth Conversions Now
Each year before your first RMD is a chance to move money from traditional to Roth at a lower tax rate. Re-run this tool annually as your balance and age change, and convert amounts that keep you under a target bracket. Even converting 3-5% of a large traditional balance each pre-RMD year can materially shrink future forced withdrawals.

Verify the Still-Working Exception in Writing
If you plan to rely on the still-working exception, confirm with your plan administrator that the plan permits it and that you own less than 5% of the employer. Do not assume — an undocumented assumption that fails triggers the full 25% penalty on the missed RMD. Get the deferral in writing before the deadline passes.
Real-World Examples
Robert Thought Age 72 Applied to Everyone
Robert, born in 1953, assumed everyone started RMDs at 72 and waited. But SECURE 2.0 pushed his cohort to age 73. He had almost missed the shift until a financial review flagged that his first RMD was due the year he turned 73. The correction gave him one extra full year for Roth conversions before forced withdrawals began.
Linda Used Three Pre-RMD Years Wisely
Linda, born in 1961, had until age 75. With the help of her advisor she mapped the five-year runway between retiring at 70 and her first RMD and converted $60,000 a year from her traditional IRA to Roth, staying inside the 22% bracket. By the time RMDs started, her taxable required amount was over a quarter smaller than it would have been.
Marcus Missed and Paid for It
Marcus turned 73 in 2024 but assumed his 401(k) administrator would auto-distribute. No distribution was made. When he discovered the omission the next year, the 25% excise penalty on the missed amount plus regular income tax cost him several thousand dollars. He corrected it within the two-year window to get the penalty down to 10% and now reconciles his RMDs every December.
Glossary of Terms
- Required Minimum Distribution (RMD)
- The minimum amount you must withdraw each year from pre-tax retirement accounts once you reach the IRS-mandated age, calculated from your balance and a life-expectancy factor.
- SECURE 2.0 Act

- Still-Working Exception
