How does a Roth conversion ladder work?
By Secure Retirement PlannerUpdated
If you retire before 59½, a Roth conversion ladder lets you reach your traditional IRA or 401(k) money without the 10% penalty. You convert part of it to a Roth IRA each year. Each converted amount can come out penalty-free once its own 5-year clock ends. If you convert any time in 2026, your date is January 1, 2031.
The ladder only solves a penalty problem, and the penalty ends at 59½. If you are already 59½ or older, you can take converted money out tax-free and penalty-free right away. You still get the main benefit of yearly conversions. You pay tax at a low rate now, before RMDs can push you into a higher bracket.

The short version
- Each year's conversion is one rung. Five years later, that rung can come out with no tax and no penalty.
- You need other money to live on for the first five years.
- Converted dollars come out before earnings. Earnings stay locked until 59½.
- Low-income early retirement years let you convert at 10% or 12%, but conversions also count as income for ACA health insurance.
- Over 59½, skip the ladder logic. Convert to fill a low bracket and withdraw whenever you like.
How does the 5-year rule work for each rung?
Each of your conversions has its own 5-year clock for the 10% penalty. Your clock starts on January 1 of the year you convert, not the day you do it. So if you convert on December 20, 2026, that money is penalty-free on January 1, 2031. That is a little over four years later.
When you withdraw, the IRS uses a fixed order. Your regular contributions come out first, then your conversions, oldest first, then earnings. The ladder works because your old conversions come out before the newer ones and before any earnings. Our guide to The 5-year rules covers both Roth clocks.
| Converted any time in | Penalty-free from | Months from a December conversion |
|---|---|---|
| 2026 | January 1, 2031 | About 49 |
| 2027 | January 1, 2032 | About 49 |
| 2028 | January 1, 2033 | About 49 |
| 2029 | January 1, 2034 | About 49 |
| 2030 | January 1, 2035 | About 49 |
Do I need a Roth conversion ladder if I'm over 59½?
No. Once you're 59½, the 10% penalty doesn't apply to your converted money at all. You can convert in March and withdraw in April with no tax or penalty on the converted dollars.
The ladder pays off most if you retire in your 40s or early 50s. If you retire at 56, only the rungs from your first year or two would ripen before 59½. So the ladder does little for you.
What still matters for you after 59½ is the tax side. You convert in years when your income is low. That's bracket filling, and it's covered in How much to convert each year.
How do I pay for the first five years?
This is the hard part. You need about five years of spending outside your IRA. You also need money for the tax on each conversion. You will likely use a mix of the options below.
| Source | Tax | 10% penalty | Catch |
|---|---|---|---|
| Taxable brokerage or cash | Only on gains, interest and dividends | No | You need to have saved it |
| Past Roth IRA contributions | No | No | Limited to what you put in |
| Rule of 55 (401(k) of the job you left) | Yes, ordinary income | No | Left the job in or after the year you turned 55; employer plan only |
| 72(t) equal payments | Yes, ordinary income | No | Must continue 5 years or until 59½, whichever is later |
| Conversion ladder rungs | Tax paid at conversion | No, after 5 years | Five-year wait for each rung |
How much tax does each rung of the ladder cost?
Each conversion is taxed as ordinary income in the year you convert. With no paycheck, your income is often low in early retirement. So your rungs can be taxed at 10% or 12%.
For 2026, if you are married with no other ordinary income, you can convert $133,000 before leaving the 12% bracket. That is your $32,200 standard deduction plus $100,800. If you are single, you can convert $66,500.
If you buy health insurance on the ACA marketplace, each conversion also counts as income for your premium tax credit. In 2026 the credit stops above 400% of the poverty line, $84,600 for a couple. See Early retirees before 65 before you size a rung.
What are the downsides of a Roth conversion ladder?
It works as designed, but it asks you for a lot of planning and cash up front.
- You need years of spending saved outside your retirement accounts. Many people don't have it.
- Your earnings stay locked. Only converted dollars come out penalty-free before 59½.
- Tax law, brackets and ACA rules can change over your 10-year plan.
- You can't undo a conversion. If the market drops after you convert, your tax stays the same.
- If you roll a 401(k) into an IRA to start the ladder, you give up the Rule of 55 on that money.
Example: a couple retiring at 50 in 2026
Ana and Luis were both born in early 1976 and retire at 50 in 2026. They have $1,000,000 in traditional IRAs and $320,000 in a taxable brokerage account. They plan to spend $60,000 a year.
Each year from 2026 to 2030 they convert $60,000. Their brokerage account pays about $4,000 of qualified dividends a year. After their $32,200 standard deduction, the conversion is taxed at 10% and 12%. That is about $2,840 a year, or 4.7%. The dividends fall in the 0% capital gains bracket.
They live on the brokerage account until 2030. That takes about $300,000 for spending plus about $14,200 in conversion tax. From January 1, 2031, the 2026 rung is ready. Each January after that, a new one ripens. They reach 59½ in mid-2035, when the ladder is no longer needed.
Their household income stays near $64,000, below the 2026 ACA cutoff of $84,600 for a couple. So they can still qualify for a premium tax credit.
If you plan to retire early, the ladder works only if you have enough outside money to cover your first five years. If you are already past 59½, you can skip the waiting and focus on your tax bracket.
| Conversion year | Converted | Federal tax | Withdraw penalty-free from | Age that year |
|---|---|---|---|---|
| 2026 | $60,000 | about $2,840 | January 1, 2031 | 55 |
| 2027 | $60,000 | about $2,840 | January 1, 2032 | 56 |
| 2028 | $60,000 | about $2,840 | January 1, 2033 | 57 |
| 2029 | $60,000 | about $2,840 | January 1, 2034 | 58 |
| 2030 | $60,000 | about $2,840 | January 1, 2035 | 59 (59½ in mid-2035) |
Hypothetical example using 2026 federal brackets and the standard deduction (IRS Rev. Proc. 2025-32) for every year, married filing jointly, with no other income besides $4,000 of qualified dividends. It ignores state tax, inflation, investment growth and any sale of brokerage shares. Your numbers will differ.
Step by step
Move workplace money to a traditional IRA
A ladder is simplest from a traditional IRA, where you control the timing. If you left your job in or after the year you turned 55, keep some money in the 401(k) first. The Rule of 55 only works from the employer plan.
Convert one year of spending
Convert about one year's living costs to a Roth IRA by December 31. A December conversion still counts from January 1 of that year.
Live on other money for five years
Use a taxable brokerage account, cash, or past Roth contributions while the first rungs age.
Repeat each year
Convert another year of spending every year, so a new rung ripens each January.
Start withdrawing in year six
From then on, each year you withdraw the rung converted five years earlier and convert another one.
Common questions
What is a Roth conversion ladder in simple terms?
You convert some traditional IRA money to a Roth IRA every year. Each year's conversion can be taken out with no penalty five years later, even before 59½.
Does each rung need its own 5 years?
Yes. Each conversion has its own 5-year clock for the 10% penalty, counted from January 1 of the conversion year.
Is a Roth conversion ladder worth it after 59½?
The ladder part isn't needed, because there is no penalty after 59½. Converting in low-income years can still lower your lifetime taxes.
Can I build a ladder from my 401(k)?
Usually by rolling it to a traditional IRA first. Some plans allow in-plan Roth conversions, but each still follows its own 5-year clock.
Are the earnings in my Roth available after five years too?
Not before 59½ without tax and possibly the penalty. Earnings come out last and are tax-free only after 59½ once your first Roth IRA is five years old.
Is a conversion ladder better than 72(t) payments?
It's more flexible, since you choose each year's amount. But 72(t) payments start right away, while a ladder needs five years of other money first.
