Required Minimum Distribution (RMD)
Key Takeaways
- RMDs are mandatory annual withdrawals from tax-deferred retirement accounts
- RMDs must begin by April 1 of the year following the year you turn 73
- The RMD amount is calculated by dividing the December 31 account balance by a life expectancy factor
- Failure to take the full RMD results in a 25% excise tax on the shortfall
Definition
A Required Minimum Distribution (RMD) is the minimum amount that must be withdrawn annually from tax-deferred retirement accounts such as traditional IRAs, 401(k)s, 403(b)s, and 457 plans once the account owner reaches age 73. RMDs ensure that the government eventually collects income taxes on money that received tax-deferred treatment.
The SECURE Act 2.0 raised the RMD starting age from 72 to 73, effective in 2023, and will increase it to 75 beginning in 2033. This gives retirees more time to let their accounts grow before mandatory withdrawals begin.
Importantly, Roth IRAs are not subject to RMDs during the owner's lifetime. This makes Roth IRAs valuable for those who do not need the funds and want to continue tax-free growth. Roth 401(k)s were previously subject to RMDs, but starting in 2024, they are also exempt.
How It Works
The RMD for each year is calculated by dividing the account balance as of December 31 of the prior year by the applicable life expectancy factor from IRS Uniform Lifetime Table III. For example, at age 73, the divisor is approximately 26.5. If your traditional IRA was worth $500,000 on December 31, your RMD would be approximately $18,868 ($500,000 ÷ 26.5).
The divisor decreases each year as life expectancy shortens, meaning RMDs increase as a percentage of the account balance over time. At age 80, the divisor is approximately 20.2, and at age 90, it is approximately 12.2. This creates progressively larger mandatory taxable distributions.
Failure to take the full RMD by December 31 (or April 1 for the first year) results in a 25% excise tax on the shortfall (reduced from 50% by SECURE 2.0). If corrected within two years, the penalty drops to 10%. This severe penalty makes RMD compliance essential for retirement planning.
Example
At age 73, your combined traditional IRA and 401(k) balances total $800,000 on December 31. Using the Uniform Lifetime Table divisor of 26.5, your RMD is $30,189. This amount must be withdrawn and is taxed as ordinary income. At a 22% tax rate, you owe $6,642 in federal taxes on the RMD. If you fail to withdraw the full amount, a 25% penalty on the shortfall applies on top of regular income taxes. Over the next 10 years, as your divisor shrinks and (if investments grow) your balance increases, your annual RMDs could grow to $50,000-$70,000+.
Why It Matters
RMDs represent the government's claim on decades of tax-deferred investment growth. They can significantly impact your tax bracket in retirement, especially if you have large tax-deferred balances. Planning for RMDs should begin years before they start, potentially through strategies like Roth conversions in lower-income years to reduce future RMD amounts.
For investors, understanding RMDs is crucial for managing taxable income in retirement. Large RMDs can push retirees into higher tax brackets, increase Medicare premiums, and trigger taxation of Social Security benefits. Proactive Roth conversion strategies can minimize these impacts.
Advantages
- RMD calculation is straightforward using IRS life expectancy tables
- The SECURE 2.0 delay to age 73 (and 75 in 2033) gives more years of tax-deferred growth
- Penalty reduction from 50% to 25% provides more forgiveness for honest mistakes
- Qualified charitable distributions can satisfy RMDs without increasing taxable income
Limitations
- Mandatory withdrawals may push retirees into higher tax brackets
- Large RMDs can increase Medicare premiums and Social Security taxation
- No flexibility to reduce RMDs once they begin (aside from Roth conversions beforehand)
- 25% penalty for missed or insufficient distributions remains severe
