The Roth Conversion Ladder: Tapping Your IRA Early, By the Rules

How the Ladder Works

Money in a traditional IRA can be withdrawn before age 59 and a half only with ordinary income tax plus a 10% early-distribution tax. A Roth conversion moves the money into a Roth IRA, where it becomes Roth principal, and converted principal can be withdrawn without the penalty once the conversion is five taxable years old. A ladder is one conversion each year. The amount you convert this year becomes money you can spend without the penalty five years from now, and each year's conversion is called a rung.

Two rules make the ladder work better than it first sounds. The clock on each rung starts on January 1 of the year you convert, whatever the actual date. A conversion made in December 2026 has been counting since January 1, 2026, and its money is free of the penalty on January 1, 2031, about four years and one month later. The income tax is paid at conversion, in a year you picked because your income was low, so the money carries no further income tax when it comes out. The ladder moves the tax on your IRA into your lowest-income years, and the five-year wait removes the penalty.

Conversions have no income limit and no age limit, and a conversion made in 2018 or later cannot be undone, so each rung is sized before it is made. Conversions also do not count against the once-a-year IRA rollover limit, so converting every year is allowed. The mechanics of moving the money, including why each conversion should go directly from custodian to custodian, are on our 60-day rollover rule guide.

The Two 5-Year Clocks People Confuse

A Roth IRA has two different 5-year rules, and they do different jobs.

• The per-conversion penalty clock. Each conversion carries its own 5-taxable-year period. Withdrawing the converted amount inside that period triggers the 10% penalty on the part that was taxable when you converted. The rule stops someone from converting on Monday and withdrawing penalty free on Tuesday. The penalty applies only to the taxable part of the conversion, so converted basis carries no penalty. The standard exceptions still work, so at 59 and a half, or on death or disability, the conversion clocks stop mattering.
• The earnings clock. Growth inside the Roth is tax free only when two things are true. You need a qualifying event (59 and a half, death, disability, or a first home purchase) and five taxable years must have run since the first year you put anything into any Roth IRA. The earnings clock exists once per person, starts with your first contribution or conversion, and once satisfied stays satisfied.

In practice, the ladder spends conversions, which need only their own clocks, while earnings stay locked until 59 and a half no matter how old the rungs are. A ladder run correctly leaves the earnings alone, so they keep compounding tax free for the decades after 59 and a half. The second rule leads to one inexpensive step. Open a Roth with a small contribution now, years before any ladder, because the earnings clock starts on that first dollar.

What Comes Out First: The Ordering Rules

You do not choose which dollars leave a Roth. Every withdrawal is treated as coming out in a fixed order, starting with regular contributions (always free of tax and penalty, at any age), then conversions, oldest year first, with the taxable part of each conversion counted before its basis, and earnings last. All of your Roth IRAs count as one account for this purpose, so opening a separate account for the ladder does not change the tax result.

For a ladder, the ordering rule helps. The oldest rung is always treated as spent first, so a steady ladder produces a steady stream of penalty-free money with no elections to file. Any Roth contributions you made over the years also come out before any rung, free of tax and penalty, which can shorten the five-year gap described in the next section.

The custodian does not track any of this. The statement does not show the age of each rung, and the 1099-R issued at withdrawal does not know the ladder exists. The record is your own set of Form 8606 filings, one for each conversion year, with the running basis figures on them. A ladder means a paper trail kept for ten years or more. Your CPA keeps that record, and the consult makes sure someone is assigned the job.

The 5-Year Gap You Must Bridge

The cost of the ladder is the wait. The first rung cannot be spent for five taxable years, so the plan needs about five years of living expenses from money outside the ladder. The usual sources are taxable brokerage accounts (often taxed at capital-gains rates well below ordinary income, sometimes at 0%), cash, and Roth contribution basis, which always comes out first and free. A working spouse's income or rental income can also cover part of the gap. A retiree who has none of this money usually should not start a ladder, and the alternatives section below is written for that retiree.

Sizing each rung is a bracket calculation, the same one described on our Roth conversion window page for people between retirement and age 73, and our Roth conversion calculator prices it in one pass. Convert enough to fill the low brackets, stop before the higher ones, and repeat each year. An early retiree has a second limit, the health-insurance subsidy, and in 2026 that limit became a fixed line again.

The 2026 Change: The Subsidy Cliff Is Back

A ladder run before 65 usually goes with health insurance bought on the ACA marketplace, and the premium tax credit that lowers the premium is computed from your income, including every converted dollar. The enhanced credits, which had no income ceiling, expired on January 1, 2026. For 2026 the law returned to the earlier structure, a sliding credit up to 400% of the federal poverty level and no credit at all above that line. One conversion dollar over the line can remove the entire year's credit, which can be thousands of dollars, repaid at filing time. A bill to restore the enhanced credits passed the House in January 2026 and had not become law as of August 17, 2026, so plan on the 400% limit.

The change also dates the advice you read. Ladder guides written between 2021 and 2025 assumed the enhanced credits, when a large conversion year reduced the subsidy gradually. In 2026 the same conversion can end the subsidy for the year. Each rung is now priced twice, once against your tax bracket and once against the 400% line, and in some years the right rung stops a dollar short of the line. Your CPA models that with the year's actual numbers before the conversion. December, when the year's income is known, is the usual month to do it.

Ladder vs Rule of 55 vs 72(t) Payments

The ladder is one of three legal ways to reach retirement money before 59 and a half without the 10% penalty, and the other two fit some people better.

• The rule of 55. Leave your job in or after the year you turn 55 (50 for certain public-safety employees) and distributions from that employer's plan carry no penalty. No conversions and no waiting period are involved. The exception belongs to the plan. Roll the 401(k) into an IRA, which is a common step at retirement, and the rule of 55 no longer applies to that money. Anyone at 52 who plans to leave work at 55 should get advice before rolling that 401(k) over.
• 72(t) substantially equal periodic payments. The IRS allows penalty-free distributions at any age on a fixed schedule of payments computed under one of three approved methods. The interest rate used may be as high as 5% or 120% of the federal mid-term rate, whichever is greater, which makes the payments larger than they were before 2023. The schedule must run for the longer of five years or until 59 and a half. Changing it, even by accident, brings back the penalty on every payment already taken, with interest. A 72(t) schedule fits someone who needs pretax income now and has no other money to live on, and it fits poorly for someone who wants flexibility. One change is permitted, a one-time switch to the required-minimum-distribution method, which produces the smallest payment.
• The ladder is the flexible choice. You choose the size of each rung and can skip a year or stop entirely, and nothing is recaptured. The cost is the five-year wait and the savings needed to cover it. Some plans combine the approaches, with rule-of-55 money or a modest 72(t) schedule covering the near years while the first rungs wait out their five years.

Every Rung Is State-Tax-Free in Florida

Each rung is ordinary income in the year of conversion, and in most states that means a state income tax bill every year the ladder runs. Florida has no state income tax, so a ladder run by a Florida domiciliary pays no state tax on any rung. The order of steps matters, as it does on the conversion window page. Establish domicile first and make the large conversions after, because a high-tax state can still tax conversion income if the move is not complete. The steps that establish Florida domicile are on our declaration of domicile guide. Florida law also protects IRAs and Roth IRAs, including inherited ones, from creditors, and that protection covers the accounts the ladder fills.

What Happens to the Ladder at Death or Incapacity

A ladder runs for 10 to 20 years. The tax rules at death are favorable, and an agent can keep the ladder running during incapacity, but both depend on the paperwork being in order.

The penalty ends at death. The 10% early-distribution tax never applies to distributions after death, so your heirs can reach every rung at once, whatever its age. Converted principal passes to them free of income tax. The earnings clock keeps running after your death on your original start date, so if you die within five years of your first Roth dollar, earnings your heirs withdraw before that clock runs are taxable. A small contribution made early, to start the clock, avoids that result. Heirs generally must empty the account within 10 years, and the payout rules and trust questions on the receiving side are covered on our trust-as-IRA-beneficiary guide and inherited IRA RMD calculator.

Incapacity stops the conversions. Each rung needs a decision and a signature every year. If a stroke or dementia takes away the signer's capacity, the conversions stop, and nobody can act on the accounts without a court guardianship unless a durable power of attorney gives an agent authority over the retirement accounts. Florida law also requires certain powers, including the power to create or change a beneficiary designation, to be listed one by one with your signature or initials next to each, so a general grant of authority does not include them. An agent with the right document and written instructions about the ladder can keep converting on schedule. Our Florida power of attorney guide covers the requirements.

Every new account needs a beneficiary form. A ladder usually opens at least one new Roth account, sometimes several at different custodians, and every new account starts with no beneficiary named. An estate plan signed at 40 does not reach an account opened at 46 unless someone names the beneficiary on that account. We check the designation on every account at the consult, and the check takes about ten minutes.

Frequently Asked Questions

Common Situations

The December conversion that stopped a dollar short. A 47-year-old couple, two years into a ladder, plans their usual conversion. Their CPA runs the year's numbers in December and finds the planned conversion would put them over the 400% line that returned in 2026, which would cost them the entire year of premium credits. The conversion is reduced to stop just under the line, and the difference converts the next year instead. The ladder runs a little slower, and the family keeps thousands of dollars in credits that a guide written in 2023 would not have warned them about.

The 401(k) that almost rolled over. An engineer of 53 plans to retire at 55 and, following a checklist, starts the paperwork to move his 401(k) into his IRA. The consult catches the problem. Leaving work at 55 would make every dollar in that plan penalty free under the rule of 55, and the rollover would have ended the exception and forced a five-year ladder wait instead. The 401(k) stays in the plan and pays his expenses from 55 to 60 directly, and the ladder is built for the years after, at half the size and half the tax cost of the original plan.

The ladder that outlived its builder. A widow calls about her husband's accounts, four years of conversions across two custodians, one of which held an account opened partway through the ladder with no beneficiary named. The named accounts pass to her outside probate and free of the penalty, even with rungs under five years old, because the penalty does not apply after death. The account with no beneficiary pays to the estate under that custodian's default terms and waits on the probate court. The difference between the two outcomes is a beneficiary form that takes about ninety seconds to complete.
