Required Minimum Distribution Calculator: Avoiding the RMD Penalty

Required Minimum Distributions (RMDs) force you to withdraw a portion of your traditional IRA and 401k balance each year starting at age 73. The penalty for failing to take the full RMD: 25% of the shortfall (reduced to 10% if corrected within 2 years).

The purpose is to ensure the IRS eventually collects tax on money that has been compounding tax-deferred. You cannot defer forever.

When RMDs Start (SECURE 2.0 Update)

| Birth Year | RMD Starting Age | |-----------|-----------------| | Before 1951 | 70.5 (already in RMD phase) | | 1951-1959 | 73 | | 1960 or later | 75 |

The SECURE 2.0 Act pushed the starting age from 72 to 73 for most current retirees, and to 75 for those born in 1960 or later.

Accounts Subject to RMDs

Requires RMDs:

• Traditional IRA
• SEP-IRA
• SIMPLE IRA
• Traditional 401k
• Traditional 403b
• Traditional 457b

Does NOT require RMDs:

• Roth IRA (during owner's lifetime)
• Roth 401k (after 2024, thanks to SECURE 2.0)

This is one of the major advantages of Roth accounts: no forced distributions, more control over when you pay taxes.

How to Calculate Your RMD

RMD = Prior Year December 31 Balance / IRS Life Expectancy Factor

The life expectancy factor comes from IRS Uniform Lifetime Table (Publication 590-B).

Sample factors (Uniform Lifetime Table):

| Age | Life Expectancy Factor | |-----|----------------------| | 73 | 26.5 | | 75 | 24.6 | | 80 | 20.2 | | 85 | 16.0 | | 90 | 12.2 | | 95 | 9.1 |

Example calculation:

Traditional IRA balance on December 31 (prior year): $750,000 Age at December 31 of distribution year: 74 Life expectancy factor: 25.5

RMD = $750,000 / 25.5 = $29,412

You must withdraw at least $29,412 from this IRA during the year.

When the First RMD Is Due

Your first RMD is due by April 1 of the year after you turn 73. All subsequent RMDs are due by December 31.

If you delay the first RMD to April 1, you will have two RMDs in that calendar year: the one for the previous year (taken by April 1) and the one for the current year (due December 31). Having two in one year can push you into a higher tax bracket and increase Medicare IRMAA surcharges.

In most cases, taking the first RMD in the year you turn 73 rather than delaying is better tax planning.

Still Working? 401k RMD Exception

If you are still employed at 73 and do not own more than 5% of the company, you can delay 401k RMDs until you actually retire. This exception applies to your current employer's plan only. Old 401k plans from previous employers and all IRAs still require RMDs at 73.

Rolling old 401k balances into your current employer's 401k before you turn 73 can consolidate balances under the still-working exception. Check with the receiving plan on whether it accepts incoming rollovers.

RMD Aggregation Rules

You can take your IRA RMD from any one or combination of your IRAs — you do not have to take a separate RMD from each account. The total RMD is calculated across all traditional IRAs combined.

401k plans are different: the RMD must be taken separately from each 401k plan.

Qualified Charitable Distributions (QCDs)

If you are 70.5 or older, you can transfer up to $105,000 directly from your IRA to a qualified charity. This counts toward your RMD but is excluded from your gross income.

For retirees who do not need the RMD income, a QCD is the most efficient giving strategy. It avoids income tax on the distribution entirely.

Frequently Asked Questions

Can I reinvest my RMD after taking it?

Yes. After taking your RMD (and paying the tax), you can invest the after-tax proceeds in a taxable brokerage account, Roth IRA (if you are under the income limit), or anywhere else. The money is yours to use as you choose after meeting the withdrawal requirement.

What if I have multiple IRAs?

Calculate the total RMD across all traditional IRAs combined, then withdraw from any IRA(s) in any combination. The only requirement is that the total withdrawn equals or exceeds the aggregate RMD.

Are inherited IRAs subject to RMDs?

Yes, and the rules changed significantly under the SECURE Act. Most non-spouse beneficiaries who inherited IRAs after December 31, 2019 must fully distribute the account within 10 years. Some beneficiaries (surviving spouses, minor children, disabled individuals) still qualify for lifetime distribution rules. The rules are complex and professional guidance may be warranted for large inherited accounts.
