A 60-year-old retiree converted $400,000 from a traditional IRA to a Roth, let it ride for a few years, and went to pull out some of the gains. He was well past 59 1/2, so he assumed the growth was his to take tax-free. It wasn't. He owed ordinary income tax on every dollar of earnings he withdrew, because his Roth IRA itself was only a few years old.
The reason was the Roth IRA 5-year rule, which most investors think of as one rule. It isn't. It's five separate clocks that run on different timelines, start on different dates, and answer different questions. Schwab and Fidelity both publish guidance noting the rule is misunderstood often enough to cost real money. We see the same pattern in our planning work, especially with clients moving toward retirement, exiting a business, or sorting out an inheritance.
This post walks through all five clocks, with a hypothetical example for each. The examples are illustrative. Names and numbers are fictional. The mechanics are real, and they're the same mechanics that drive Roth strategy inside our planning engagements.
Clock 1: The contribution clock
This is the one most people think about when they hear "5-year rule."
To withdraw earnings from a Roth IRA tax-free, the account must have been open for five tax years AND you must be 59 1/2 or older (or meet an exception like death, disability, or a first-time home purchase up to $10,000). Contributions can always come out tax-free and penalty-free. The clock applies to growth, not basis.
The clock starts on January 1 of the tax year of your first Roth IRA contribution, even if you funded it in April for the prior year. Once that clock starts, it covers every Roth IRA you ever open. You only get one contribution clock across all your Roth IRAs.
Hypothetical. James, a Destin business owner, opens his first Roth IRA in March 2026 and contributes for tax year 2025. His clock starts January 1, 2025. The earliest he can withdraw earnings tax-free is January 1, 2030, assuming he's also over 59 1/2 by then. If he opens a second Roth IRA in 2028, the 2025 clock still controls. He doesn't restart.
Planning takeaway. If you've never funded a Roth IRA, a small contribution today (even $50) starts the clock for everything you do later. We sometimes recommend a token Roth IRA contribution to a client years before any actual Roth strategy kicks in, simply to start the meter. (See our retirement planning page for how this fits into a broader sequence-of-returns and tax strategy.)
Clock 2: The conversion clock
This is the clock most people assume caught the 60-year-old retiree in the opening example. It didn't, because the conversion clock's only consequence is a penalty, and he was past 59 1/2. But the confusion between this clock and the contribution clock is exactly the problem, and it's the one we see clients miss most often.
Each Roth conversion gets its own 5-year clock, separate from the contribution clock. The conversion clock answers a narrow question: can you withdraw the converted amount without triggering the 10% early-withdrawal penalty on the pre-tax dollars you just converted? If you pull a conversion out within five years AND you're under 59 1/2, the IRS treats it as if you took an early distribution from the original traditional IRA. That means a 10% penalty on the pre-tax amount converted, even though no extra income tax is due (you already paid that at conversion).
Two important nuances:
-
Once you're 59 1/2, the conversion clock's penalty stops mattering. You're past the age where the 10% early-withdrawal penalty applies. But the contribution clock (Clock 1) still controls whether earnings come out tax-free.
-
Each conversion has its own clock. A 2024 conversion finishes its clock January 1, 2029. A 2026 conversion finishes January 1, 2031. If you're running a multi-year Roth conversion ladder, you're tracking multiple clocks at once.
Hypothetical. Margaret makes her first-ever Roth IRA contribution in 2024, then converts $400,000 from her traditional IRA in 2025, at age 60. By 2028 the account has grown to roughly $520,000: about $407,000 of basis (her small 2024 contribution plus the $400,000 conversion) and roughly $113,000 of earnings. She withdraws $460,000 to help a child buy a house. Under the ordering rules, the first ~$407,000 comes out as basis, tax-free and penalty-free (she's past 59 1/2, so the conversion clock's penalty is moot). But the last ~$53,000 dips into earnings, and her contribution clock isn't satisfied until January 1, 2029. That $53,000 comes out as ordinary income. Margaret was right about her age and wrong about her clock. Had she withdrawn only $407,000 or less, nothing would have been taxable.
Planning takeaway. If you're 59+ and considering a large conversion, the conversion clock probably won't bite you. The contribution clock might. We model both before recommending a conversion, and we time large conversions to interact deliberately with the clock that will actually govern your future withdrawals.
Clock 3: The designated Roth (Roth 401(k)) clock
Roth 401(k), Roth 403(b), and Roth governmental 457(b) accounts are called designated Roth accounts. They follow rules that look like Roth IRAs but aren't identical.
Each plan has its own clock. Funding a Roth 401(k) at a previous employer does not start the clock at your new employer's Roth 401(k). If you change jobs three times and open Roth 401(k)s at each, you're tracking three plan-level clocks.
The bigger trap is the pro-rata distribution treatment. With a Roth IRA, any withdrawal you make is treated as coming from contributions first, then conversions, then earnings. You can pull your basis out at any time, tax-free, even if the account is brand new. With a designated Roth in an employer plan, you can't. Any non-qualified distribution is treated as a proportional mix of contributions and earnings. Even if the dollars in the account are 90% your own contributions and 10% growth, 10% of every dollar you withdraw is taxable earnings if the 5-year clock isn't satisfied.
Hypothetical. Robert leaves a job in 2027 at age 56 and considers taking $30,000 out of his Roth 401(k), which he opened in 2024. The plan is three years old. His contributions are 80% of the balance and earnings are 20%. The IRS treats his $30,000 withdrawal as $24,000 contributions (tax-free) and $6,000 earnings (taxable as ordinary income, plus a 10% penalty because he's under 59 1/2). If he had rolled the Roth 401(k) to a Roth IRA first and had a Roth IRA already open since 2017, the contribution-first ordering rules and his older Roth IRA clock would have given him very different treatment.
Planning takeaway. Designated Roths inside employer plans are a different instrument than Roth IRAs even when they look the same on a statement. SECURE 2.0 eliminated Roth 401(k) RMDs in 2024, which removed one reason to roll them out, but the pro-rata withdrawal rule remains a reason to consider rolling to a Roth IRA before any withdrawal is taken.
Clock 4: The rollover clock (and the trap that catches everyone)
This is the clock that costs people the most money, and it's the most counterintuitive.
When you roll a Roth 401(k) into a Roth IRA, the receiving Roth IRA's clock controls, not the Roth 401(k)'s. The years you held the Roth 401(k) don't carry over to the Roth IRA on their own. If you're rolling into a brand-new Roth IRA, a 15-year Roth 401(k) becomes a brand-new Roth IRA for purposes of the contribution clock.
The saving move: if you have any Roth IRA already open (even one with $50 in it), the earlier Roth IRA's clock governs. Roll a 15-year Roth 401(k) into an old Roth IRA you funded back in 2010, and the rolled-over money is treated as fully aged.
Roth IRA to Roth IRA rollovers are simpler. The original Roth IRA's clock carries over to the receiving Roth IRA.
Hypothetical. Susan, age 62, retires from a corporate job in 2027. She's been contributing to her employer's Roth 401(k) since 2012, fifteen years of contributions and growth. Say the balance is $400,000: $250,000 of her own contributions and $150,000 of earnings. She rolls the entire balance into a Roth IRA she opens at the same time. In 2028 she withdraws $350,000 for a second home. The first $250,000 is her rolled-over contribution basis, tax-free. But the next $100,000 dips into earnings, and the receiving Roth IRA's 5-year clock only started in 2027, so those earnings come out taxable as ordinary income (no penalty, since she's past 59 1/2). Had she opened a Roth IRA with a single small contribution in any prior year, that older clock would have governed and the entire balance, earnings included, would have come out tax-free. The cost of that oversight on a sizeable Roth 401(k) can run into the tens of thousands.
Planning takeaway. Before any Roth 401(k) rollover, we check whether the client has an existing Roth IRA. If they don't, we usually advise opening one and making a small contribution at least one full tax year before the rollover, if eligibility and timing allow. We also confirm that in-plan rollovers (Roth 401(k) inside the plan) are permitted, because not every plan sponsor allows them. This is exactly the kind of coordination that disappears when people DIY a rollover at a custodian's website. See our approach to comprehensive planning for how rollovers fit into broader transition planning.
Clock 5: The inherited Roth clock (and the 10-year stack)
When you inherit a Roth IRA, you inherit the original owner's contribution clock too. If the original owner first funded a Roth IRA in 2015, the 5-year rule was satisfied by 2020, and you can withdraw earnings tax-free even if you only inherited the account yesterday.
If the original owner's account was less than 5 years old at death, earnings withdrawn before the 5-year mark are subject to ordinary income tax. No 10% penalty applies on withdrawals due to death, regardless of your age.
The inherited Roth sits at the intersection of the 5-year rule and a second, less-forgiving rule: the SECURE Act 10-year drain. For most non-spouse beneficiaries of accounts inherited after 2019, the entire Roth IRA must be emptied by December 31 of the tenth year after the original owner's death. Roth IRAs are tax-free on the way out (assuming the original 5-year clock was satisfied), so there's no income-tax urgency. But there's still tax-free growth urgency. Stretching a Roth across multiple decades was a multi-generational wealth strategy. The 10-year window collapses that.
Eligible designated beneficiaries are exempt: surviving spouses, minor children of the decedent (until age 21), the chronically ill, the disabled, and individuals not more than 10 years younger than the deceased. The disability exception is the one we work with most often.
Hypothetical. The Andersons name their adult daughter, who has an intellectual disability and qualifies as a disabled designated beneficiary, as the beneficiary of their Roth IRA. The Roth IRA was first funded in 2010, so the 5-year contribution clock is satisfied many times over. Because she's disabled, she's exempt from the 10-year drain. She can stretch distributions over her own life expectancy, preserving tax-free growth for decades.
Same Andersons, different beneficiary: their daughter has no disability. She inherits a Roth IRA opened in 2010. The 5-year clock is satisfied. But the 10-year rule means she has until the end of year 10 to empty the account. There's no income-tax cost in pulling it out, but pulling it out is mandatory.
Same Andersons again, but they named a special needs trust as beneficiary instead of the daughter directly. Now the picture changes again. Whether the SNT counts as a "see-through" trust, whether it's a conduit or accumulation trust, and how the trust's beneficiary qualifies under the eligible designated beneficiary rules all determine whether the stretch is preserved or the 10-year drain applies. The trust language drafted by an estate attorney five years ago can make the difference between a 40-year stretch and a 10-year drain.
Planning takeaway. Roth IRA beneficiary planning interacts with estate planning, special needs planning, and tax planning all at once. We coordinate this directly with attorneys when clients name trusts as Roth IRA beneficiaries, because the most expensive mistakes are made on documents drafted before anyone thought about RMDs or stretch eligibility. See our special needs planning page for how this fits into broader benefit-preservation work.
How the clocks fit together
Three rules that hold across all five clocks:
-
The contribution clock is one clock for life. Start it as early as you can, even with a token amount, and it covers everything you do later in Roth IRAs.
-
Conversion clocks run in parallel. Each conversion year creates its own 5-year track. A multi-year Roth conversion strategy means tracking multiple clocks simultaneously, especially if you're converting in your 50s.
-
Designated Roth accounts and rollovers don't automatically inherit your Roth IRA's age. Plan-level clocks and rollover mechanics can reset what feels like a "clearly aged" account back to zero.
These rules don't make Roth strategy unworkable. They make it specific. A 55-year-old physician approaching retirement, a 62-year-old business owner who just sold a company, and a 40-year-old parent of a disabled child are all running Roth strategies inside completely different clock structures, and the right move for one is often the wrong move for the others. That's the work.
What to do next
If you have a Roth IRA, a Roth 401(k), or both, three concrete questions are worth answering before your next withdrawal, rollover, or conversion:
- When did each of your Roth clocks actually start? Pull the original account-opening statements. Don't rely on memory.
- If you're planning a conversion in the next two years, what does it do to your contribution-clock posture for withdrawals you might need at 60, 62, or 65?
- If you've named anyone other than a spouse as a Roth IRA beneficiary, has anyone modeled the 10-year drain against your projected balance and their tax bracket?
If you'd like to walk through these in your own situation, reach out for a conversation. We work with families along 30A and nationwide, and Roth strategy is one of the planning lanes where small details compound into very large outcomes.
Hypothetical examples are illustrative only. Actual outcomes depend on individual circumstances, IRS guidance in effect at the time of any transaction, and the specific terms of your retirement plan, IRA custodial agreement, and any applicable estate documents. The rules summarized here reflect current IRS guidance as of the date of last review. Tax laws and IRS interpretations change. Confirm with a qualified tax advisor before acting.
