Plan Your Roth Ladder →Last updated February 2026 · 2025 IRS tax data
A Roth conversion ladder is a strategy to access Traditional IRA or 401k funds before age 59½ without paying the 10% early withdrawal penalty.
Here's how it works: You convert money from a Traditional account to a Roth IRA, pay income tax on the conversion (but no penalty), then wait 5 years. After 5 years, that converted amount can be withdrawn completely tax-free and penalty-free.
By starting conversions in your first year of early retirement, you create a "ladder" where each year's conversion becomes available 5 years later, providing a continuous stream of accessible funds.
Convert $40,000 from Traditional IRA to Roth. Pay taxes on conversion (around 12% if done strategically). Live off taxable brokerage accounts.
Each year, convert another $40,000. Continue living off taxable accounts and/or Roth contributions (which can be withdrawn anytime).
Your Year 1 conversion ($40k) is now 5 years old. Keep converting and continue waiting.
Withdraw your Year 1 conversion ($40k) tax-free and penalty-free. Your ladder is now producing $40k/year indefinitely.
Normally, withdrawing from a 401k before 59½ costs a 10% penalty. The Roth ladder eliminates this.
In early retirement, your income is low. Convert at 10-12% instead of working-years rates of 22-32%.
Most early retirees have the majority of savings in tax-advantaged accounts. This makes them accessible.
Once in the Roth, all future growth and withdrawals are completely tax-free forever.
Plan conversions years in advance. Know exactly when each chunk becomes available for tax-free withdrawal.
Roth IRAs have no required minimum distributions during your lifetime and pass tax-free to beneficiaries.

Here is a complete year-by-year Roth conversion ladder for someone retiring at 45 with $1.2M in a Traditional 401k and $300K in taxable brokerage.
| Year | Age | Action | Convert Amount | Tax Cost (~12%) | Roth Available |
|---|---|---|---|---|---|
| 2026 | 45 | Convert, live off taxable | $40,000 | $860 | $0 |
| 2027 | 46 | Convert, live off taxable | $40,000 | $860 | $0 |
| 2028 | 47 | Convert, live off taxable | $40,000 | $860 | $0 |
| 2029 | 48 | Convert, live off taxable | $40,000 | $860 | $0 |
| 2030 | 49 | Convert, live off taxable | $40,000 | $860 | $0 |
| 2031 | 50 | First rung accessible! | $40,000 | $860 | $40,000 |
| 2032 | 51 | Second rung accessible | $40,000 | $860 | $80,000 |
In this example, each $40K conversion (MFJ with standard deduction) costs only ~$860 in federal tax because the $31,400 standard deduction reduces taxable income to $8,600, all within the 10% bracket. Compare this to withdrawing from the 401k while working, when that same $40K would be taxed at your marginal rate of 22% or 24%. The tax savings can be over $5,000 per conversion, adding up to tens of thousands over the ladder's lifetime.
Each conversion has its own independent 5-year clock. Converting $40K in January 2026 makes that $40K accessible in January 2031. Converting $40K in December 2026 makes that tranche accessible in January 2031 as well (the IRS counts calendar years, not exact dates). This is why BridgeToFI tracks each conversion individually with a seasoning queue.
Yes. Your original Roth IRA contributions (not conversions or earnings) can be withdrawn anytime, at any age, tax and penalty-free. This is separate from the conversion ladder. If you contributed $6,000/year for 15 years, you have $90,000 in accessible Roth basis regardless of age. BridgeToFI tracks this as P2 (accessible with some restrictions) because contribution basis is always available.
You need other bridge funds: taxable brokerage accounts, Roth contribution basis, savings, or part-time income. This is why the first 5 years of early retirement require careful planning. A common approach is to have 5 years of expenses in P1 (taxable brokerage) while building the Roth ladder. BridgeToFI calculates exactly how much bridge money you need for these critical first years.
Almost never. Large conversions push you into higher tax brackets, defeating the purpose. The optimal strategy is converting enough each year to fill a low bracket. For a married couple filing jointly in 2025, you can convert roughly $96,950 in taxable income (after the $31,400 standard deduction) and stay entirely in the 10% and 12% brackets. Most early retirees convert $15,000 to $50,000 per year, depending on their other income sources.
Roth conversions count as taxable income and increase your Modified Adjusted Gross Income (MAGI). This can reduce or eliminate ACA premium tax credits. The key is balancing conversion amounts against subsidy thresholds. For a household of two in 2025, keeping MAGI below approximately $78,880 (300% FPL) or $105,000 (400% FPL) preserves meaningful subsidies. Converting too much in one year can cost thousands in lost healthcare subsidies.
Roth contributions are money you put directly into a Roth IRA during working years (up to $7,000/year in 2025). Contribution basis is always accessible penalty-free. Roth conversions are rollovers from a Traditional IRA or 401(k) into a Roth IRA. You pay income tax on the converted amount, and converted funds must "season" for 5 years before penalty-free withdrawal. BridgeToFI tracks each conversion individually in a queue and automatically graduates them to accessible basis after the waiting period.
Yes. There are no income limits on Roth conversions (sometimes called the "mega backdoor" or simply backdoor Roth). While direct Roth IRA contributions phase out at $161,000 to $176,000 for single filers in 2025, anyone can convert Traditional IRA funds to Roth regardless of income. This is particularly useful for high earners who retire early into a low-income period, allowing them to convert at much lower tax rates than they paid during their career.
Once you reach age 59.5, all Roth IRA withdrawals (including conversions and earnings) become penalty-free regardless of the 5-year rule. The 5-year seasoning only matters for conversions withdrawn before 59.5. This means the Roth ladder strategy is most valuable from retirement until 59.5. After that, your Traditional accounts are also penalty-free, giving you maximum flexibility.
The optimal conversion amount depends on your tax bracket, other income, and ACA subsidy eligibility. Here are common scenarios for 2025.
| Scenario | Filing Status | Conversion Amount | Effective Tax Rate | Strategy |
|---|---|---|---|---|
| Fill standard deduction only | MFJ | $31,400 | 0% | Tax-free, preserves ACA subsidies |
| Fill 10% bracket | MFJ | $55,250 | ~4.3% | Very low tax cost |
| Fill 12% bracket | MFJ | $128,350 | ~9.4% | Best value for most early retirees |
| Fill standard deduction only | Single | $15,700 | 0% | Tax-free conversions |
| Fill 12% bracket | Single | $64,175 | ~10.4% | Good balance for single filers |
These amounts assume no other taxable income in the conversion year. If you have Social Security, pension, or part-time income, reduce conversion amounts accordingly. BridgeToFI's progressive bracket mode shows your exact effective and marginal rates at any conversion level, making it easy to find the sweet spot for your situation.
Jake and Sarah, both 48, retire with $1.8M. Their portfolio: $350K taxable brokerage (P1), $50K Roth contributions (P2), and $1.4M in Traditional IRA/401(k) (P3). Annual spending: $65,000. Filing married jointly.
Year 1 (Age 48): Start the Ladder
They convert $55,250 from Traditional IRA to Roth. After the $31,400 standard deduction, taxable income is $23,850, all in the 10% bracket. Federal tax: $2,385. They pay living expenses from taxable brokerage. Conversion starts its 5-year clock.
Years 2 through 4 (Ages 49 to 51): Keep Converting
Same conversion each year. Taxable brokerage covers expenses ($65K/year). After 4 years, they have spent roughly $260K from P1 and have 4 conversion batches seasoning in the Roth.
Year 5 (Age 52): Ladder Produces Income
The Year 1 conversion ($55,250) is now seasoned and accessible penalty-free. They withdraw it to cover expenses. Taxable brokerage (P1) is preserved as backup. Each subsequent year, another conversion seasons.
Year 12 (Age 59.5): Full Access
All retirement accounts are now penalty-free. The ladder is no longer needed, but years of low-bracket conversions have moved hundreds of thousands from taxable Traditional to tax-free Roth. Total tax paid on conversions over 12 years: roughly $28,600. Without the ladder, withdrawals at higher future tax rates could have cost $80,000 or more.
The Tax Cuts and Jobs Act (TCJA) expires after 2025. Without congressional action, tax brackets revert to higher pre-2018 rates in 2026. This creates urgency for Roth conversions.
The 12% bracket covers income up to $96,950 for MFJ filers. This means a married couple can convert up to $128,350 ($96,950 + $31,400 standard deduction) at an effective rate of roughly 9.4%. These are historically low rates for this income level.
If TCJA expires, the current 12% bracket reverts to 15%, the 22% bracket becomes 25%, and the 24% bracket becomes 28%. The same $128,350 conversion that costs roughly $12,000 in tax today could cost $16,000 or more under reverted rates. That is a significant difference compounded over decades of tax-free Roth growth.
Early retirees in the bridge period should consider accelerating Roth conversions while TCJA rates are in effect. Converting at 12% now is better than converting at 15% or 25% later. BridgeToFI models current 2025 brackets with inflation adjustment and includes a TCJA sunset note so you can plan accordingly.
A $200K conversion in one year pushes you into the 22% or 24% bracket. Spreading that over 4 to 5 years at $40K to $50K keeps you in the 10% to 12% range, saving thousands in taxes. Patience pays off with Roth ladders.
Roth conversions increase your MAGI, which can reduce or eliminate ACA premium tax credits. A $5,000 conversion pushing you above 400% FPL could cost $10,000+ in lost subsidies. Always model the full picture before converting.
The ladder takes 5 years to produce accessible funds. If you retire with only 3 years of P1 bridge money, you will run short before the first conversion seasons. Plan for at least 5 to 6 years of accessible funds.
Roth conversions are taxed as ordinary income at the state level too. If you live in a high-tax state (California, New York), consider timing conversions for years when you reside in a no-income-tax state. Some early retirees relocate specifically for this reason.
