Understanding IRAs and RMDs: A Guide to Retirement Withdrawals

By Laima Zirne and Tahir Mahmood | 19 May, 2025

As you plan for retirement, it’s essential to understand how Individual Retirement Accounts (IRAs) and Required Minimum Distributions (RMDs) work.

Key Terms

Before we begin, let’s define a few key terms to set the stage:

Traditional IRA – a tax-deferred retirement account where contributions may be tax-deductible, and withdrawals in retirement are taxed as ordinary income.

Roth IRA – a retirement account where contributions are made with after-tax dollars, but qualified withdrawals are tax-free.

401(k) – an employer-sponsored retirement plan that allows employees to contribute pre-tax income, with taxes due upon withdrawal.

RMD (Required Minimum Distribution) – the minimum amount that must be withdrawn annually from certain retirement accounts starting at a specified age. These rules ensure that retirees eventually begin withdrawing — and paying taxes on — money they have saved in tax-deferred retirement accounts. Recent changes from the SECURE Act have shifted the landscape, especially for inherited accounts.

How RMDs Are Calculated:

The IRS uses mortality tables — specifically the Uniform Lifetime Table — to determine how long you’re expected to live and spread your withdrawals accordingly. Each year, your account balance is divided by a number based on your age. As you age, this number gets smaller, so your RMD amount increases.

Final Thoughts

RMDs are a key part of retirement planning. Failing to take them on time can lead to hefty penalties — up to 25% of the missed amount (reduced from 50% under SECURE Act 2.0). Understanding when and how much to withdraw based on your situation is crucial, especially with changing rules and exceptions.
