How Account Type Changes the Rules for Required Minimum Distributions

The Rule Most People Have Heard

If you have spent any time reading about retirement, you have probably encountered the phrase "required minimum distribution," often shortened to RMD. The common summary goes something like this: once you reach a certain age, the government requires you to start pulling money out of your retirement accounts each year. That summary is accurate as far as it goes, but it leaves out a detail that can meaningfully affect how much you owe in taxes during retirement.

According to IRS guidance, owners of traditional IRAs, SEP IRAs, SIMPLE IRAs, and many employer-sponsored retirement plans generally must begin taking annual RMDs when they reach age 73. That is the age rule most articles focus on. But the age is only half the story. The other half is the account type. Not every account labeled "retirement" carries the same lifetime withdrawal requirement.

Why Age Is Only Part of the Answer

The reason RMDs exist is straightforward. Traditional retirement accounts are funded largely with pre-tax dollars. When you contributed to a traditional IRA or a workplace 401(k), you often did so before income tax was applied, and the money grew without being taxed along the way. In exchange for that upfront tax break, the IRS eventually wants its share. The RMD is the mechanism that ensures those dollars do not sit untaxed indefinitely. Beginning at age 73, the account owner must withdraw a minimum amount each year, and that withdrawal is generally counted as taxable income.

This is why the account type matters. The tax treatment on the way in shapes the withdrawal requirement on the way out. Accounts that were already taxed before the money went in are treated differently.

Roth Accounts Follow a Different Path

Here is the distinction that surprises many savers. The IRS states that Roth IRAs and designated Roth accounts held inside 401(k) or 403(b) plans are not required to take withdrawals until after the account owner's death. In plain terms, if you own a Roth IRA, you are not forced to take money out during your lifetime under the RMD rules that apply to traditional accounts.

The logic follows the same tax principle. Roth contributions are made with money that has already been taxed. You did not receive an upfront deduction, so the IRS has no waiting share to collect through mandatory annual withdrawals. Qualified distributions from a Roth generally come out tax-free, and there is no lifetime pressure to begin drawing the account down.

It is worth noting the specific wording. The exemption from lifetime RMDs applies to the original account owner. That is a narrower statement than "Roth accounts never have RMDs," and the difference matters when you look further down the line.

What Happens to Beneficiaries

The lifetime rule for the original owner is not the same as the rule for the people who inherit the account. The IRS notes that beneficiaries can still be subject to RMD requirements. In other words, the account owner may never be required to take a distribution during life, but the individuals who inherit a Roth account after the owner's death can face their own set of withdrawal obligations.

This is an important nuance for anyone thinking about how their accounts will pass to children or other heirs. The absence of a lifetime RMD for the owner does not automatically mean the account will remain untouched by distribution rules forever. It simply means the rule that applies during the owner's life differs from the rule that applies to a beneficiary.

How This Shapes Taxable Income in Retirement

The practical consequence of these differing rules shows up in your annual taxable income. With a traditional IRA or a similar pre-tax account, reaching age 73 introduces required withdrawals that count as income whether or not you need the money that year. Those distributions can raise your taxable income and, depending on your overall situation, may influence how other parts of your finances are taxed.

A Roth IRA does not create that same forced income during your lifetime. Because you are not required to take distributions, the account can stay invested, and you retain control over whether and when to withdraw. That flexibility is one of the reasons account type is such a central piece of retirement tax planning rather than a minor technical detail.

Two Accounts, Two Sets of Rules

The key takeaway is that the label "retirement account" hides real differences. Two accounts can both help you save for later years, yet the IRS does not treat them identically when it comes to lifetime required withdrawals. A traditional IRA, SEP IRA, SIMPLE IRA, or many employer plans generally trigger RMDs at age 73. A Roth IRA or a designated Roth account inside a workplace plan does not require lifetime withdrawals from the original owner.

Understanding which category each of your accounts falls into is the first step toward understanding how your income might look in your seventies and beyond. The age gets the headlines, but the account type does much of the quiet work behind the numbers.
