Every other retirement account eventually forces the owner’s hand. Traditional IRAs and 401(k)s carry required minimum distributions — annual withdrawals the government demands starting at a set age, whether the money is needed or not, each one taxed as income. A Roth IRA is the exception the tax code carved out. Its owner is never required to take a single dollar out during life, which makes it the rare account that can be left completely alone to compound, and quite possibly the best money a retiree can leave to the next generation.
The account with no required minimum distribution
Because contributions to a Roth IRA are made with money that was already taxed, the government has no future tax to collect from it and no reason to force withdrawals. Federal rules impose no required minimum distribution on the original Roth owner at any age. A traditional-account holder pulling a mandatory distribution each year is steadily shrinking the balance and paying tax on every withdrawal; a Roth owner can leave the entire account untouched for a decade or more.
That single difference reshapes how the account behaves in retirement. The required-distribution rules that govern traditional retirement money simply do not reach a Roth during the owner’s lifetime, so the balance keeps growing tax-free instead of being drawn down on the government’s schedule. For a retiree with other income to live on, that turns the Roth into a long-running, tax-free compounding machine.
It also gives the owner control over their own tax picture. Under the IRS rules for Roth IRAs, qualified withdrawals do not count as taxable income, so tapping one does not lift adjusted gross income the way a traditional distribution does. That can keep a retiree under the thresholds that tax Social Security benefits or trigger higher Medicare premiums — a lever a forced traditional distribution takes away.

Why it is the smartest dollar to leave behind
The absence of forced withdrawals is exactly what makes a Roth so powerful as an inheritance. Money that never had to be pulled out keeps compounding untaxed for the full length of the owner’s life, so the balance handed down is often larger than a comparable traditional account that was being drained by annual distributions. And the inheritance itself passes to heirs income-tax-free — they receive the money without owing federal income tax on the withdrawals, the same treatment the original owner enjoyed.
That is a sharp contrast to a traditional IRA, where every dollar an heir withdraws is taxed as ordinary income, often landing during the heir’s peak earning years at their highest rate. Leaving a Roth instead of a traditional account can mean the difference between an heir keeping the full balance and handing a quarter or more of it to the IRS. For families thinking about what to spend first, the logic points one way: draw down the taxable accounts during retirement and let the Roth ride.
The account also names its own beneficiary. Like other retirement accounts, a Roth passes by beneficiary designation rather than through a will, so it moves to the named heir without probate — provided the paperwork with the custodian is current. A stale or missing beneficiary form can send even a Roth into the estate and undo that advantage.
The ten-year clock heirs inherit along with the money
The “never forces withdrawals” rule belongs to the original owner; heirs live under a different one. Under current law, most non-spouse beneficiaries who inherit a Roth generally must empty the account within about ten years of the owner’s death. The crucial detail is that those withdrawals are still tax-free — the ten-year rule dictates the timing, not a tax bill. An heir can let the inherited Roth keep growing untaxed and take it all in the final year, or spread it out, but cannot hold it forever the way the original owner could.
A surviving spouse gets a better deal. A spouse who inherits a Roth can typically treat it as their own, folding it into their name and once again facing no required distributions during their lifetime — effectively restarting the tax-free hold for another generation. Certain other heirs, such as a minor child or a disabled beneficiary, also fall outside the strict ten-year clock and can stretch withdrawals over a longer horizon, though the details turn on the beneficiary’s exact status. The IRS guidance for beneficiaries lays out how the spousal and ten-year rules apply.
Put together, those rules make the Roth a deliberate estate tool rather than an accident of good saving. The owner who leaves it untouched hands down a larger, tax-free balance; the heir who understands the ten-year window can time the withdrawals to their own advantage and still owe nothing. The decision a retiree faces is really about spending order — which account to lean on first — and for anyone who can afford to leave the Roth alone, the math consistently favors spending it last and passing it on.
