A Roth conversion ladder can create a rolling source of Roth IRA principal before age 59½. It cannot pay next month’s bills.
Each taxable conversion has its own five-tax-year period. While you wait, your living expenses, health insurance, and conversion taxes must come from cash, taxable investments, Roth contribution basis, earned income, or another penalty exception. That makes the five-year bridge the first decision.
In nearly three decades as a financial planner, I saw plans fail for a simple reason: the conversion schedule looked elegant, but the accessible cash was barely enough to support it. The ladder only works when the bridge works.
Quick Answer
A Roth conversion ladder is a series of annual transfers from a traditional retirement account to a Roth IRA. The taxable portion of each conversion is included in income for that year, and each conversion begins a separate five-tax-year period for purposes of the additional 10% tax while you are under age 59½. You fund the waiting period with other accessible assets, then older conversion amounts enter the Roth withdrawal ordering sequence as their periods expire. Before choosing a conversion amount, confirm that you can fund five years of spending, conversion taxes, and a reasonable reserve.
Key Takeaways Ahead
How a Roth Conversion Ladder Works
A Roth conversion ladder is a delayed pipeline. You move money into the Roth IRA now, pay the conversion tax now, and plan to use the converted principal later.
- Convert: Move an amount from a traditional IRA or eligible workplace plan into a Roth IRA.
- Pay the tax: Include the taxable portion of the conversion in that year’s ordinary income.
- Start the clock: The conversion’s five-tax-year period begins on January 1 of the conversion year, even when the transaction occurs later in the year.
- Fund the bridge: Use other accessible assets while that conversion is inside its five-year period.
- Repeat annually: Add a new conversion rung while an older rung moves closer to the end of its period.
For example, a conversion completed in December 2026 begins its five-year period on January 1, 2026. Its period generally ends before January 1, 2031. The IRS Roth IRA distribution rules also require you to apply the Roth ordering rules when money is withdrawn.[1]
| Conversion year | Five-year period begins | First date generally after that conversion period | Planning role |
|---|---|---|---|
| 2026 | January 1, 2026 | January 1, 2031 | First rung |
| 2027 | January 1, 2027 | January 1, 2032 | Second rung |
| 2028 | January 1, 2028 | January 1, 2033 | Third rung |
| 2029 | January 1, 2029 | January 1, 2034 | Fourth rung |
| 2030 | January 1, 2030 | January 1, 2035 | Fifth rung |
The table shows the timing pipeline. It does not let you select one conversion as a separate bucket when you withdraw money. Roth IRA ordering rules still control which dollars are treated as distributed first.
The Five-Year Bridge Is the Feasibility Test
Your bridge is the money that remains accessible before the first conversion rung is ready or before another penalty exception makes the ladder unnecessary.
Count more than regular monthly spending. Your bridge may need to cover:
- Housing, food, transportation, and ordinary living costs
- Marketplace premiums and out-of-pocket health costs
- Federal and state taxes generated by the conversions
- Home repairs, vehicles, travel, and other irregular expenses
- A cash reserve for a bear market or an income interruption
Answer These Questions Before You Convert
- How many years must the bridge cover? Count the period until age 59½, the first completed conversion period, a pension, Social Security, employment income, or another accessible account takes over.
- How much will you actually spend? Include taxes, insurance, irregular expenses, and inflation rather than multiplying this year’s monthly budget by 60.
- Which assets are accessible now? Identify cash, taxable investments, documented Roth contribution basis, governmental 457(b) money, earned income, or a qualifying workplace-plan exception.
- Where will the conversion tax come from? Paying the tax from outside funds often allows more money to reach the Roth IRA, provided it does not weaken the bridge.
- What happens during a market decline? Decide which account will fund spending when selling investments would lock in a large loss.
- What is the backup plan? Identify spending that can be reduced, work that can be resumed, or retirement timing that can change.
Decision Rule
If five years of accessible spending, conversion taxes, and a reasonable reserve would consume nearly all of your bridge assets, the ladder is not ready. Improve the bridge before increasing the conversions.
📋 Track Your Roth Conversion Rungs Before You Spend Them
A Roth conversion ladder looks simple on paper. Five or ten years later, remembering which dollars were contributions, which year each conversion occurred, and what you’ve already withdrawn gets harder.
- → Record each Roth conversion by tax year
- → Keep contribution basis separate from conversions
- → Track previous Roth IRA withdrawals
- → Build a cleaner record before you start spending ladder rungs

Keep the Two Roth Five-Year Rules Separate
The phrase “Roth five-year rule” hides two different clocks that matter here.
The Per-Conversion Penalty Period
Each conversion and qualifying rollover has a separate five-tax-year period. If you withdraw the taxable portion while you are under age 59½ and the applicable period has not ended, the additional 10% tax may apply unless another exception covers the distribution.[1]
Reaching age 59½ generally provides an exception to the additional early-distribution tax. That is why a ladder started at age 55 may have limited value as an early-access strategy. The person may reach age 59½ before the first new rung completes five tax years.
The Qualified-Distribution Clock
A separate five-year period helps determine whether Roth IRA earnings can be distributed tax-free. A qualified distribution generally requires satisfaction of the Roth IRA participation period plus age 59½, death, disability, or a qualifying first-home distribution.
Completing a conversion’s separate five-year period does not automatically make every dollar of Roth earnings tax-free. For the complete treatment, read the Roth IRA five-year-rule guide.
Roth Withdrawal Ordering Controls What Comes Out
You cannot label a Roth IRA withdrawal and choose which bucket the IRS should treat as distributed.
For a nonqualified Roth IRA distribution, the ordering rules generally treat money as coming out in this sequence:
- Regular Roth IRA contributions
- Conversion and rollover contributions, first in, first out
- Earnings
Within a conversion, the taxable portion is generally treated as coming out before the nontaxable portion. The aggregation rules group all of your Roth IRAs for this purpose.[1]
Do You Need a Separate Roth IRA for Every Rung?
No. Separate accounts may help your personal recordkeeping, but they do not create separate IRS withdrawal queues. The ordering and aggregation rules still apply across your Roth IRAs.
Maintain a Conversion Ledger
Keep one record for each tax year that includes:
- Conversion date and tax year
- Gross amount converted
- Taxable and nontaxable portions
- Source account and Roth custodian
- Five-year starting date
- First year generally outside the conversion period
- Forms 1099-R, 5498, and 8606 when applicable
- Remaining documented regular Roth contribution basis
Do not assume a future custodian statement will reconstruct ten years of tax history for you.
Example: Dana’s Ladder Fails Before It Starts
Hypothetical Scenario
Dana retires at age 50 with $300,000 in cash and taxable investments, $900,000 in a traditional IRA, and planned spending of $60,000 per year. She wants to convert $50,000 annually. For illustration, assume the conversions create an average combined federal and state tax cost of $8,000 per year, and she wants a $30,000 contingency reserve. These figures illustrate the bridge test and are not a tax projection.
| Year | Starting bridge | Living expenses | Conversion taxes | Remaining bridge | Status |
|---|---|---|---|---|---|
| Year 1 | $300,000 | $60,000 | $8,000 | $232,000 | On track |
| Year 2 | $232,000 | $60,000 | $8,000 | $164,000 | On track |
| Year 3 | $164,000 | $60,000 | $8,000 | $96,000 | On track |
| Year 4 | $96,000 | $60,000 | $8,000 | $28,000 | Below the $30,000 reserve |
| Year 5 | $28,000 | $60,000 | $8,000 | -$40,000 | Fails |
Dana’s bridge falls below her desired reserve in Year 4 and drops below zero in Year 5. She needs $370,000 to fund the modeled spending, conversion taxes, and $30,000 ending reserve. Her $300,000 bridge is short by $70,000.

Important: This simplified model assumes the same spending, conversion, tax rate, and other income each year. It does not model investment returns, inflation, ACA premium-tax-credit changes, capital-gain harvesting, IRMAA, tax-bracket interactions, or account-specific withdrawal rules. Confirm the strategy with current tax and health-insurance information before acting.
She could repair the plan by combining several changes:
- Work longer or earn part-time income during the bridge
- Reduce initial spending
- Use documented Roth contribution basis for part of the bridge
- Lower the annual conversion amount
- Build a larger taxable reserve before retiring
- Preserve access under the Rule of 55 when eligible
- Use another approved early-distribution strategy for part of the income need
The conversion amount and the spending amount solve different problems. Treating them as the same number is one of the easiest ways to overbuild the ladder.
How Much Should You Convert Each Year?
Your annual conversion amount should sit between two boundaries.
- The planning floor: The amount worth moving to reduce a credible future problem, such as large RMDs, compressed tax brackets after a spouse dies, or unfavorable beneficiary taxation.
- The current ceiling: The amount you can convert before current taxes, ACA costs, IRMAA exposure, state taxes, or bridge pressure become unattractive.
Some years, that workable range may be zero.
Review all income that can use the same tax and MAGI space:
- Interest and dividends
- Realized capital gains
- Consulting or business income
- Pensions and Social Security
- Rental income
- Other retirement-account distributions
Roth Conversions Compete With 0% Capital-Gain Harvesting
Early retirement can create an opportunity to realize long-term capital gains at a 0% federal rate. That opportunity depends on overall taxable income. Ordinary income from a Roth conversion fills taxable-income space before the preferential capital-gain bands are applied.[8]
Within the relevant income range, another dollar of ordinary conversion income can push a dollar of long-term gain out of the 0% band and into the 15% band. The exact result depends on filing status, deductions, other income, and the amount of gain realized.
Michael Explains
Low-income years create valuable tax space. You may use that space for Roth conversions, capital-gain harvesting, or a combination. Decide which use creates the larger after-tax benefit before filling the bracket automatically.
State Tax and Relocation Can Change the Conversion Year
A large conversion before a move can create state income tax that might have been avoided after establishing residency elsewhere. A move can also affect capital gains, insurance pricing, and estate-planning rules.
Do not let taxes alone dictate a move, but include the timing in the conversion analysis. See the guide to moving to a state with no individual income tax.
Use the Roth conversion calculator to model the income-tax side, then separately add ACA, capital-gain, state-tax, IRMAA, and bridge effects. The broader Roth conversion planning guide covers the general question of whether and how much to convert.

How ACA Coverage Changes the 2026 Conversion Decision
Before Medicare, a Roth conversion generally increases household income used to determine the premium tax credit.
For 2026, premium-tax-credit eligibility generally requires household income of at least 100% and no more than 400% of the federal poverty line. The 2026 applicable-percentage table ranges from 2.10% to 9.96% of household income, depending on the household’s percentage of FPL.[4][5]
This means ACA costs can increase before you reach the 400% ceiling. A conversion can reduce the credit gradually as income rises, then eliminate eligibility when final household income moves above 400% FPL.
Watch Out: The Repayment Cap Is Gone for 2026
For tax years after 2025, there is no repayment cap on excess advance premium tax credits. If advance credits paid to the insurer exceed the credit allowed on the tax return, the full difference is added to the household’s tax liability. A late-year Roth conversion can therefore reduce the current credit and create a repayment bill for assistance already used during the year.[4]
Update the Marketplace estimate when income changes. A conversion, realized capital gain, business payment, or other income event can materially change the reconciliation on Form 8962.
The 2026 Rule Is Still Politically Contested
H.R. 1834 passed the House on January 8, 2026, and would extend the enhanced premium-tax-credit rules through 2028, including eligibility above 400% FPL. The measure was placed on the Senate calendar on February 10, 2026. It had not become law as of August 6, 2026.[6]
Confirm the current law before a large fourth-quarter conversion. A retroactive change would require the ACA portion of the conversion analysis to be recalculated.
Florida Readers: Going Too Low Can Also Create a Coverage Problem
Florida remained a non-expansion Medicaid state in the latest CMS state dataset available for this review. Marketplace premium-tax-credit eligibility generally begins at 100% FPL. An early retiree who deliberately suppresses household income below that level may lose Marketplace assistance and may not qualify for Medicaid under Florida’s adult eligibility rules. Verify eligibility before using a low-income target as a planning goal.[9][10]
When Another Early-Access Strategy May Fit Better
A Roth conversion ladder rewards patience. It does not solve an immediate cash shortage during the waiting period.
| Reader need | Strategy to investigate | Main tradeoff |
|---|---|---|
| Immediate access to the plan from the employer you left at or after the qualifying age | Rule of 55 | The money generally must remain in the qualifying employer plan, and the plan controls available distribution options. |
| Immediate, scheduled IRA income | Section 72(t) substantially equal periodic payments | The payment program is rigid, and an improper modification can create recapture consequences.[3] |
| Access to an eligible governmental 457(b) | Governmental 457(b) distributions | The additional 10% tax generally does not apply, except to certain amounts rolled into the plan from another account.[2] |
| Five-year bridge is already funded and flexibility matters | Roth conversion ladder | Taxes and MAGI rise now, while access to conversion principal is delayed. |
| No reliable bridge and no usable exception | Later retirement, lower spending, or additional earned income | The retirement date or lifestyle target may need to change. |
The IRS early-distribution exception chart shows that the Rule of 55 applies to qualified employer plans rather than IRAs, while eligible governmental 457(b) distributions generally receive separate treatment.[2]
How IRMAA and RMDs Affect Ladder Sizing
ACA costs shape many pre-Medicare conversion years. Medicare IRMAA becomes more important as the two-year lookback approaches.
For 2026, Social Security generally uses 2024 tax-return information. IRMAA begins above $109,000 of MAGI for an individual return and $218,000 for a joint return. The standard 2026 Part B premium is $202.90 per month, and the first IRMAA tier raises the total Part B premium to $284.10.[7]
A conversion at age 63 can therefore affect Medicare premiums at age 65. Keep this section of the ladder analysis narrow and use the dedicated Roth conversion and IRMAA guide for the full timing decision.
Reducing a traditional account can also reduce future required minimum distributions. Under current IRS guidance, the applicable age is generally 73 for people born from 1951 through 1958. Proposed regulations place people born in 1959 at age 73, resolving a statutory drafting ambiguity, and people born in 1960 or later generally have an applicable age of 75.[11]
RMD reduction can support larger conversions now, but it does not override current tax, ACA, IRMAA, state-tax, or bridge constraints.
Your Annual Roth Conversion Ladder Checklist
- Recalculate the bridge. Update spending, accessible assets, contribution basis, insurance, taxes, and the contingency reserve.
- Estimate income before converting. Include interest, dividends, gains, work, pensions, rental income, and other distributions.
- Compare competing uses of tax space. Decide how much room should go to Roth conversions and how much should remain available for capital-gain harvesting.
- Model ACA consequences. Estimate the current credit, applicable premium percentage, 400% FPL ceiling, and possible repayment of advance credits.
- Check the IRMAA lookback. Include Part B and Part D consequences when the relevant tax year can affect Medicare premiums.
- Set a conversion range. Identify the planning floor and current ceiling, then choose an amount inside the workable range.
- Confirm the transaction. Verify the source account, Roth destination, tax withholding election, custodian processing deadline, and completion date.
- Update the ledger. Save the confirmation and relevant tax forms, then record the new five-year date.
- Revisit the plan after major changes. Recalculate after a move, marriage, divorce, death, return to work, market decline, health-coverage change, or new tax law.
Frequently Asked Questions
Should I Start Roth Conversions While I Am Still Working?
Sometimes. Starting earlier begins the conversion periods sooner, but employment income can make each conversion more expensive. Compare the value of an earlier clock with the lower tax and ACA income that may become available after work ends.
Do I Need a New Roth IRA for Every Conversion?
No. Separate accounts can make personal tracking easier, but the IRS ordering rules generally aggregate your Roth IRAs. A new account for each rung does not let you choose a different tax ordering sequence.
What If I Retire at 55?
Check the Rule of 55 before rolling the employer plan into an IRA. A new conversion begun at 55 may not complete five tax years before you reach age 59½, so the ladder may serve tax planning more than early access.
What Happens If the Market Falls?
A decline can create an attractive opportunity to convert more shares for the same taxable amount. It can also weaken a bridge funded by taxable investments. Review the conversion opportunity and the spending reserve as separate decisions.
Can I Pay the Conversion Tax From the IRA?
You can withhold money from the distribution, but that amount does not reach the Roth IRA. When you are under age 59½, the withheld portion may also be subject to the additional 10% tax unless an exception applies. Review the mechanics in the Roth conversion rules guide.
How Long Should the Ladder Continue?
Continue only while the conversions solve a real access or tax-planning problem. The ladder may end when you reach age 59½, another income source begins, ACA or IRMAA costs rise, the traditional balance reaches its target, or your estate and retirement priorities change.
The Bottom Line
Begin with accessible bridge money. Confirm how many years it must cover, where the conversion taxes will come from, and how the plan survives a bad market. Then size each annual conversion after federal tax, capital gains, ACA, state tax, IRMAA, RMDs, and estate goals are considered.
The bridge comes first. The conversions come second.
