He Opened His First Roth at 64 With a $100,000 Conversion. At 67 the Growth Was Still Taxable to Withdraw, Because the Five-Year Clock Started Late

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, not the account type.

Two Clocks Doing Two Different Jobs

Two five-year rules govern Roth IRAs, and conflating them is the source of 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 a per-account clock, and once satisfied it never restarts.

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

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

Why Reaching 59½ Is Not Enough on Its Own

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

Ordering Rules Usually Soften the Damage

The IRS ordering rule for Roth withdrawals provides meaningful 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 the earnings layer does the unsatisfied clock create a tax bill.

For the headline case, any withdrawal up to the original $100,000 converted amount comes out as principal and carries no tax consequence. The growth on top is where the risk lives during the waiting period. The actual damage is usually smaller than feared and becomes real only when a saver needs to touch appreciation before the clock finishes its count.

A Planning Move That Costs a Dollar

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 in advance starts the clock for every Roth dollar that follows. As one finance expert has noted, everyone should convert at least a small amount to a Roth IRA just to get the clock moving, because even $1 is enough to establish the starting year with most custodians.

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 substantial one several years later sequences the tax outcome very differently than a single lump conversion done late in life. The clock can be five years closer to satisfied before the big money ever arrives.

Inherited Roths, Workplace Plans, and Other Exceptions

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 personally owned a Roth IRA.

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. That is why the small early-conversion strategy matters even for workers who have held Roth 401(k) balances for years. The IRS treats all of a taxpayer’s Roth IRAs as a single account for purposes of the qualification rule.

Other events that make a distribution qualified without waiting on age include death, total and permanent disability, and a first-time home purchase up to $10,000 in lifetime earnings. That $10,000 cap has been in place since 1997 and has not been raised by Congress, though legislation to increase it to $25,000 has been proposed but not enacted. The five-year clock must still have run for earnings to escape tax under any of these exceptions.

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).

If You Have No Roth at All, Open One This Year

The cheapest move a saver without a Roth can make in 2026 is to open one and fund it, even minimally. Any 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 exposure 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.

For 2026, the Roth IRA contribution limit is $7,500, with an additional $1,100 catch-up for those 50 and older, bringing the total possible contribution to $8,600. That catch-up amount rose from $1,000 in 2025, marking the first time the IRA catch-up has been indexed to inflation since 2006, a change made under the SECURE 2.0 Act. Even a contribution well below those limits is enough to start the clock. The dollar amount that starts the five-year period is not the dollar amount that determines when it ends.

Editor’s note: This pass added current 2026 Roth IRA contribution limits ($7,500; $8,600 with catch-up) and noted that the IRA catch-up increased from $1,000 to $1,100 under SECURE 2.0’s first inflation-indexing step. It also added context on the first-home purchase earnings exception, noting the $10,000 lifetime cap has not been raised despite pending legislation.
