Opening a Roth IRA at 64 with a $100,000 conversion still leaves earnings taxable for years because the five-year qualification clock starts late.

A qualified Roth distribution requires both age 59½ and a completed five-year clock, and satisfying only one of those conditions still triggers taxes on earnings.

Converting as little as $1 into a Roth IRA today starts the five-year clock for every future Roth dollar, including large conversions made later.

A 64-year-old converts $100,000 from a traditional IRA into a new Roth, pays the conversion tax, and assumes the account is now tax-free. Three years later, needing cash, they withdraw more than the converted principal and discover the growth is taxable. The account was Roth. The saver was past 59½. Timing was the problem.

Two five-year rules govern Roth IRAs, and conflating them causes this mistake. The first determines whether a distribution is qualified, meaning earnings come out entirely tax-free. It runs from January 1 of the tax year of the first contribution or conversion to any Roth IRA the taxpayer owns. It is a lifetime clock, not per-account, and once satisfied never restarts.

The second applies separately to each conversion and governs the 10% additional tax on early distributions of converted principal before 59½.

For a saver, the second rule is irrelevant because they are past 59½. The problem is purely the first rule. The qualification clock started on January 1 of the year of that first conversion at 64 and won't end until January 1 of the fifth year after. Until then, earnings pulled from the account are taxed as ordinary income.

A qualified distribution requires both conditions: the owner must be at least 59½ (or meet a specified exception), and the five-year clock must have run. Age alone satisfies only half the test. A saver whose first Roth dollar arrived at 64 satisfies the age test immediately but waits years for the clock to catch up, regardless of balance size.

The ordering rule for Roth withdrawals provides relief. Money leaves in a fixed sequence: direct contributions first, converted amounts next (oldest conversions before newer ones), and earnings last. Contributions come out tax-free and penalty-free at any age. Converted principal, for a saver past 59½, is also tax-free and penalty-free. Only when withdrawals reach earnings does the unsatisfied clock produce tax.

For the headline case, a withdrawal up to the original $100,000 converted comes out as principal. The growth on top carries the tax risk during the waiting period. Damage is usually smaller than feared and becomes real only when a saver needs to touch appreciation before the clock finishes.

Because the qualification clock starts on the first day of the tax year of the first Roth contribution or conversion, funding a token amount years ahead starts the clock for every Roth dollar that follows. As one finance expert put it, "Everyone should convert at least a minimum amount of money from an IRA to a Roth. $1 is fine with Fidelity. This way you can start the 5-year clock."

For a pre-retiree planning a large conversion at 64, converting a small amount at 59 or earlier lets the clock run in the background. A tiny first-year conversion followed by the big one several years later sequences the tax outcome very differently than a single lump conversion done late in life.

For beneficiaries, the original owner's holding period generally carries over. Someone who inherits a Roth that the decedent held for more than five years can take qualified distributions of earnings tax-free, even if the beneficiary has never owned a Roth.

Roth 401(k) accounts run on a separate clock from Roth IRAs. Rolling a Roth 401(k) into a Roth IRA does not import the workplace plan's holding period. What matters is when the receiving Roth IRA's own clock started, which is why the $1 move matters even for workers with long-held Roth 401(k) balances. The IRS treats all of a taxpayer's Roth IRAs as a single account for the qualification rule.

Other events that make a distribution qualified without waiting on age include death, total and permanent disability, and up to $10,000 for a first-time home purchase. The five-year clock still has to have run for the earnings to escape tax under any of these.

That low-tax stretch between the last paycheck and the first required withdrawal is where conversion timing does its heaviest lifting (we sized up the window in a free Roth guide here: The Roth Window).

The cheapest move a saver without a Roth can make in 2026 is to open one and fund it, even with $100. Even a small contribution makes January 1 of this tax year the starting line for the qualification clock on every future Roth dollar. A saver who opens one at 45 avoids the headline scenario entirely. Opening at 60 shortens the window. Waiting keeps the clock at zero, and if the first Roth dollar arrives late alongside a large conversion, earnings will not be freely accessible for years.
