Required Minimum Distributions: A Retirement Planning Guide

What an RMD does

Tax-deferred retirement accounts were designed to postpone income tax, not avoid it forever. RMD rules generally require distributions from traditional IRAs and many workplace plans after the owner reaches the applicable age. The distribution is generally included in taxable income, subject to account basis and other rules.

RMD starting ages have changed over time, so birth year matters. Workplace-plan rules can differ when a participant is still employed, and inherited accounts follow separate requirements. Use current IRS guidance rather than a chart saved years ago.

Planning takeaway

The first planning task is to identify which accounts are subject to which rule.

How the amount is generally calculated

For many owners, the annual amount is based on the account balance at the end of the prior year divided by a life-expectancy factor from the applicable IRS table. Different tables or rules may apply in certain spouse and beneficiary situations.

The custodian may calculate an amount, but the owner remains responsible for taking the correct total. Traditional IRA RMDs may have aggregation rules that differ from workplace plans. Do not assume one distribution from any account satisfies every account's requirement.

Why RMDs matter before they begin

A large tax-deferred balance can create taxable distributions later, even if the household does not need the cash for spending. That income may interact with Social Security taxation, Medicare income-related charges, capital gains, and state taxes. It can also change which account funds a one-time goal.

The years after retirement but before RMDs begin may offer planning flexibility because earned income has stopped while required income has not started. Whether to take additional distributions or consider Roth conversions is a tax-specific decision. Modeling can identify the years worth discussing with a tax professional.

Avoid common RMD planning mistakes

Do not wait until December to confirm the requirement, assume the age is the same for everyone, or overlook an old workplace account. Keep beneficiary designations and account records current. If the first distribution can be delayed into the following year under current rules, recognize that taking two taxable distributions in one calendar year may affect the tax result.

Penalties and correction procedures can change, and special situations are common. Verify the current requirement with the custodian and a qualified tax professional. The educational plan should flag the year and estimated cash flow, not present itself as a compliance calculator.
