RMD Age Calculator: Your First RMD Year and Deadline
Your required beginning date depends only on your birth date. The first RMD is for the year you reach your RMD age; its deadline is April 1 of the following year, and every later RMD is due by December 31. (Treas. Reg. §1.401(a)(9)-2)
| Born | RMD age | First RMD for | First deadline |
|---|---|---|---|
| 1951 | 73 | 2024 | April 1, 2025 |
| 1953 | 73 | 2026 | April 1, 2027 |
| 1955 | 73 | 2028 | April 1, 2029 |
| 1960 | 75 | 2035 | April 1, 2036 |
People born in 1959 are assigned age 73 by the proposed regulations, though the law's wording is unclear; their first RMD year would be 2032.

RMD Age 2026: Who Must Start Taking RMDs This Year
If you were born in 1953, you turn 73 in 2026 and your first RMD is for 2026. You can take it as late as April 1, 2027 — but then your 2027 RMD is also due by December 31, 2027, and both land on one tax return. (IRS: RMD FAQs)
Two groups can skip or delay:
- Roth IRAs never have lifetime RMDs, and Roth 401(k)s stopped needing them in 2024.
- Still working: your current employer's plan can usually wait until you retire, unless you own 5% or more of the company. IRAs never qualify.

Our take: take the first one in the year you reach the age
The April 1 extension sounds generous, but doubling up two RMDs in one year can push you into a higher bracket and an IRMAA tier two years later. Most people should take the first RMD by December 31. Then work out the dollar amount on the RMD calculator or the RMD table, cut it with a QCD if you give to charity, and know the cost of a slip on the missed RMD penalty calculator.
Then pick the timing: When to Take Your RMD: January, December or Monthly?
