Understanding Required Minimum Distributions (RMDs)

Understanding Required Minimum Distributions (RMDs)

May 20, 2026

Planning for retirement is a lifelong journey, but once you reach a certain age, the focus shifts from accumulating assets to strategically withdrawing them. A critical part of this transition is understanding Required Minimum Distributions (RMDs).

What are RMDs?

An RMD is the minimum amount you must withdraw from your retirement accounts each year. The IRS mandates these distributions because the funds in your traditional IRAs and 401(k)s have grown tax-deferred; RMDs ensure that the government eventually collects taxes on that income.

When Do You Need to Start?

The timeline for RMDs has evolved in recent years due to legislative changes, including the SECURE Act 2.0.

Generally, the age at which you must begin taking distributions is: 

  • Age 73: If you reached age 72 after December 31, 2022
  • Age 75: Scheduled to begin in 2033

The deadline for your first RMD is April 1 of the year following the year you turn the required age. However, delaying your first RMD until the following year could result in taking two taxable distribution in the same calendar year. All subsequent RMDs must generally be taken by December 31 each year.

How is the Amount Calculated?

The amount is not a flat rate. It is calculated annually by dividing your retirement account's year-end fair market value by a life expectancy factor provided by the IRS, typically found in the Uniform Lifetime Table. Due to your life expectancy factor changing every year, your RMD amount will also fluctuate.

Which Accounts are Subject to RMDs?

RMD rules generally apply to " 

  • Traditional IRAs
  • SEP IRAs and SIMPLE IRAs
  • Employer-sponsored retirement plans, including 401(k), 403(b), and 457(b) plans

Roth IRAs owned by the original account holder are not currently subject to lifetime RMD requirements. However, inherited Roth IRAs may still be subject to distribution rules.

Tax Considerations

RMDs are generally taxed as ordinary income in the year the distribution is received. Depending on your overall financial picture, RMDs may also impact:

  • Your Medicare premium brackets (IRMAA)
  • The taxation of Social Security benefits
  • Your overall taxable income and marginal tax rate

Proactive withdrawal planning can be an important component of a broader retirement income strategy because of these potential implications.

What Happens if You Miss an RMD?

Failing to take the full required amount may result in an IRS excise tax penalty on the amount not withdrawn. While recent legislation reduced the penalty from prior levels, it is still important to ensure RMDs are calculated and completed on time.

Final Thoughts

Understanding RMD rules is an important part of retirement planning. Staying informed about distribution requirements, tax implications, and available planning opportunities can help retirees make more informed financial decisions and avoid unnecessary penalties.
