RMD Aggregation Rules
- Multiple traditional IRAs: You calculate each account's RMD separately but can withdraw the total from any one (or any combination) of your IRAs.
- Multiple 401(k)s: Must withdraw each account's RMD from that specific account — no aggregation allowed.
- Inherited IRAs: Use the Single Life Expectancy Table, not the Uniform Lifetime Table. Non-spouse beneficiaries under SECURE Act rules must empty the account within 10 years.
Tax Impact of RMDs
RMDs are taxed as ordinary income. A large RMD can:
- Push you into a higher bracket
- Trigger IRMAA Medicare surcharges
- Cause Social Security income to become more taxable (up to 85%)
常見問題 (FAQ)
Q: At what age must I take RMDs?
A: Under the SECURE 2.0 Act (2022), the RMD starting age is 73 for anyone born between 1951 and 1959, and 75 for anyone born in 1960 or later. Roth IRAs are NOT subject to RMDs during the owner's lifetime.
Q: What happens if I miss an RMD?
A: If you fail to take your full RMD, the IRS imposes a 25% excise tax on the amount not withdrawn. If corrected within 2 years, the penalty drops to 10%. The penalty was reduced from 50% by SECURE 2.0.
Q: How is RMD calculated?
A: RMD = Account Balance (Dec 31 of prior year) ÷ IRS Life Expectancy Factor from the Uniform Lifetime Table. At age 73, the factor is 26.5, so a $500,000 balance requires an RMD of $500,000 ÷ 26.5 = $18,868.
Q: Do I need to take RMDs from a Roth 401k?
A: Prior to 2024, Roth 401(k)s were subject to RMDs. SECURE 2.0 eliminated Roth 401(k) RMDs starting in 2024 — aligning them with Roth IRAs. You can now leave Roth 401(k) funds untouched indefinitely.
