Understanding required minimum distributions

When RMDs start, how they're calculated, and how to manage the tax impact before they arrive.

The Basics

What is a Required Minimum Distribution?

A Required Minimum Distribution is the minimum amount the IRS requires you to withdraw each year from most tax-deferred retirement accounts, such as Traditional IRAs and 401(k)s.

The idea is simple: these accounts received tax benefits on the way in, and at some point the IRS expects to collect taxes as money comes out.

While the rules themselves are straightforward, the timing and tax consequences often aren’t — especially when multiple accounts, pensions, Social Security, and other income sources are involved.

Common misconception

RMDs are not a suggestion. Missing or under‑withdrawing can result in significant IRS penalties, even if the mistake was unintentional.

Timing

When do RMDs begin?

For most people today, RMDs begin at age 73. If you were born in 1960 or later, your starting age will be 75. The specific start age depends on your year of birth and current tax law.

01

Your first RMD year

Your first RMD must be taken for the year you reach your required start age. However, you’re allowed to delay that first withdrawal until April 1 of the following year.

Delaying sounds helpful — but it can mean taking two taxable distributions in the same year.

02

Every year after

After your first RMD, all future RMDs must be completed by December 31 each year. There are no extensions.

How it works

How is your RMD amount calculated?

Each year’s RMD is based on two numbers: your account balance as of December 31 of the prior year, and a life expectancy factor from the IRS Uniform Lifetime Table. Divide one by the other. That’s your required withdrawal for the year.

Straightforward case

Pat is 75 with a single Traditional IRA worth $500,000 at the end of last year. The IRS life expectancy factor for age 75 is 24.6.

Account balance $500,000
IRS factor at age 75 24.6
RMD for the year $500,000 ÷ 24.6 = $20,325

That $20,325 is added to Pat’s other taxable income for the year — Social Security, any pension, and any other withdrawals taken.

The wrinkle: mixed account types

Robin is 76 with two Traditional IRAs ($150,000 and $250,000) and a former employer’s 401(k) worth $200,000. The IRS factor at age 76 is 23.7.

IRA RMD (combined balance) $400,000 ÷ 23.7 = $16,878
401(k) RMD (separate balance) $200,000 ÷ 23.7 = $8,439
Total required $25,317

The $16,878 IRA requirement can be taken from either IRA or split between them in any proportion — the IRS only cares that the combined total is met. The $8,439 from the 401(k) must come from that plan specifically and cannot be satisfied by an IRA withdrawal.

The scenarios described are hypothetical and are intended solely to illustrate the types of financial planning services that may be provided. They do not represent the experience of any specific client. Actual client experiences and outcomes will vary depending on individual circumstances and it should not be interpreted as a guarantee of future results or client experience. Actual RMD amounts depend on prior-year account balances, account type, beneficiary designations, and applicable IRS tables. Multiple inherited accounts follow different aggregation rules. Consult a tax professional for your specific situation.

Planning ahead

Ways to reduce the impact of RMDs

RMD rules apply to traditional tax‑deferred accounts, but with proactive planning the impact can often be reduced and, in some cases, eliminated.

Gradual Roth conversions in lower‑income years
Coordinating withdrawals with Social Security and pension timing
Strategic use of charitable giving once RMDs begin
Intentional drawdowns before RMD age to smooth lifetime taxes
