One rule separates a Roth IRA from nearly every other retirement account: the original owner is never forced to take money out. A traditional IRA, by contrast, starts demanding withdrawals at age 73, whether or not the retiree needs the cash, and those withdrawals are taxed as income. That single difference reshapes how a Roth can be used late in life, turning it into an account that can keep growing untouched while a traditional IRA runs on the government’s schedule. For retirees weighing which account to lean on first, the distinction is worth real money and real flexibility.
How required minimum distributions differ by account
Traditional IRAs, along with most workplace plans like a standard 401(k), fall under required minimum distributions, or RMDs. Once the owner reaches 73, the tax code requires a minimum amount to come out each year, calculated from the account balance and a life-expectancy figure. The first withdrawal can be delayed until April 1 of the following year, but after that the deadline is the end of each calendar year, and the amount rises as the owner ages.
The required amount is not fixed but recalculated every year. It is found by dividing the prior year-end balance by a life-expectancy factor the IRS publishes, so the percentage that must come out grows as the owner gets older. The starting age has also shifted under recent law, moving to 73 and scheduled to rise to 75 later this decade, which gives some savers a few extra years before the traditional-account clock starts ticking.
A Roth IRA sits outside that system entirely. For the lifetime of the original owner there is no forced withdrawal at any age, which is confirmed in the government’s guidance on required minimum distributions. The logic is straightforward: Roth contributions were made with money already taxed, and qualified withdrawals come out tax-free, so there is no deferred tax bill the government needs to collect on a timetable. The account can be left alone to compound as long as the owner lives.

Why the Roth exemption matters for taxes and heirs
The absence of a forced withdrawal gives a retiree control over taxable income that a traditional IRA does not. A large required distribution can push a household into a higher bracket, raise the share of Social Security benefits that gets taxed, and even lift Medicare premiums through income-based surcharges. Because a Roth stays out of the RMD calculation, it lets a retiree draw income only when it makes sense, keeping taxable income lower in years when that matters most.
The control matters most in the years around big income events. A retiree who delays Social Security, sells a property, or takes on part-time work can find a forced traditional-IRA withdrawal landing in exactly the wrong year, stacking on top of other income. A Roth sidesteps that timing problem entirely, letting the owner leave the account alone in high-income years and draw on it, tax-free, when the rest of the budget runs lean.
The lifetime exemption does not extend to everyone who eventually holds the account. Most non-spouse heirs who inherit a Roth are subject to distribution rules of their own, generally a requirement to empty the account within about ten years, though the withdrawals can still come out tax-free. The details for an inherited account are laid out in the IRS publication on distributions from IRAs, and they are worth checking before assuming a Roth passes to heirs with no strings at all. A surviving spouse generally gets far more favorable treatment and can often keep the no-RMD benefit.
Roth accounts inside workplace plans have moved in the same direction. A Roth 401(k), which once carried its own lifetime distribution requirement, no longer forces withdrawals from the living owner under recent law, bringing it closer in line with the Roth IRA.
The penalty for missing a traditional-IRA RMD, and the planning window
On the traditional side, the deadlines carry teeth. Missing a required distribution once triggered a steep excise tax on the amount that should have come out, and while recent law softened it, the excise tax on a missed distribution can still take a meaningful bite, with a reduced rate available to those who correct the shortfall quickly. The burden of tracking the deadline falls on the account owner, not the custodian, which is how otherwise careful retirees end up owing a penalty.
That contrast is what makes the years before 73 a planning window. Some retirees convert part of a traditional IRA to a Roth during lower-income years, paying tax on the converted amount now to shrink the future balance that will be subject to RMDs later. The move trades a tax bill today for smaller forced withdrawals and more control down the road, and it works precisely because the Roth side has no lifetime distribution requirement to plan around.
Conversions come with their own trade-offs to weigh. The tax due on a converted amount is owed in the year of the conversion, and a large move can itself spike income, so many retirees convert in measured slices across several years. Done carefully, the strategy shrinks future required withdrawals and the taxes attached to them while shifting more of a nest egg into the one account that never forces a distribution during the owner’s life.
The open question for each household is one of timing rather than rules. The Roth’s freedom from forced withdrawals is settled and permanent for the owner, but whether to lean on it early, let it grow untouched, or fund it through conversions depends on tax brackets, health, and how much a retiree wants to leave behind. The account offers flexibility that a traditional IRA cannot, and the value of that flexibility shows up in the years a retiree chooses not to touch it.
