There is no dollar limit on how much you can rollover into a Roth IRA from another retirement account. The annual contribution cap — $7,500 for 2026, or $8,600 if you are 50 or older — governs only new money you put in directly; it does not apply when you move funds from a 401(k), 403(b), traditional IRA, or similar plan.1Internal Revenue Service. Retirement Topics – IRA Contribution Limits Someone with a $500,000 traditional IRA or a $2 million 401(k) can convert the entire balance in a single year without violating any ceiling. The real constraint is the tax bill: pre-tax dollars you move into a Roth become taxable income in the year of the conversion.
No Dollar Cap and No Income Cap on the Rollover
Federal law treats rollovers and regular contributions as separate categories. Qualified rollover contributions sit outside the annual limit, the excess-contribution penalty, and the income phaseouts that restrict direct Roth contributions.2Office of the Law Revision Counsel. 26 USC 219 – Retirement Savings3Office of the Law Revision Counsel. 26 USC 408A – Roth IRAs
The income limits are worth noting because they trip people up. For 2026, direct Roth contributions phase out between $153,000 and $168,000 of modified adjusted gross income for single filers, and between $242,000 and $252,000 for married couples filing jointly.4Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 If you earn above the top of that range, you cannot contribute directly. Those thresholds do not apply to rollovers or conversions. Regardless of your income, you can move funds from a traditional IRA, 401(k), 403(b), or governmental 457(b) into a Roth IRA.3Office of the Law Revision Counsel. 26 USC 408A – Roth IRAs
What the Conversion Will Cost in Tax
When pre-tax money moves into a Roth IRA, the converted amount is added to your ordinary income for the year. Roll over $80,000 from a traditional 401(k), and your taxable income for that year rises by $80,000. You do not owe the 10% early withdrawal penalty on the conversion itself, but you owe income tax at your regular rate.3Office of the Law Revision Counsel. 26 USC 408A – Roth IRAs
For large balances, a single-year conversion can push you into a higher tax bracket. Many people who are converting six- or seven-figure accounts spread the moves across several years to keep each year’s added income within a bracket they are comfortable paying.
The Pro-Rata Rule If You Have Mixed IRA Money
If your traditional IRAs hold both pre-tax and after-tax (nondeductible) contributions, you cannot cherry-pick the after-tax portion for a tax-free conversion. The IRS treats all of your traditional, SEP, and SIMPLE IRA balances as one pool and taxes each conversion proportionally. If 80% of the combined pool is pre-tax, 80% of any amount you convert is taxable.5Internal Revenue Service. Rollovers of After-Tax Contributions in Retirement Plans Balances inside a 401(k) or 403(b) are not part of the pool. Only IRA balances count.
You report nondeductible contributions and the taxable portion of any conversion on Form 8606. Skipping the form when it’s required carries a $50 penalty per occurrence.6Internal Revenue Service. Instructions for Form 8606
Amounts You Cannot Roll Over
A few types of distributions are ineligible for rollover at any dollar level. They have to come out as taxable distributions and cannot land in a Roth IRA:
- Required minimum distributions. Once you have reached the age RMDs apply, the year’s RMD must come out before any remaining balance can be rolled over.7Internal Revenue Service. Notice 2026-13, Safe Harbor Explanations – Eligible Rollover Distributions
- Hardship distributions from an employer plan.
- Substantially equal periodic payments based on your life expectancy.
- Loan defaults that are treated as distributions.8Internal Revenue Service. Verifying Rollover Contributions to Plans
Inherited accounts are another boundary. If you inherit a retirement account from someone other than your spouse, you generally cannot roll those funds into your own Roth IRA. Surviving spouses can roll an inherited account into their own IRA; non-spouse beneficiaries are limited to distributions under the account’s existing rules.9Internal Revenue Service. Retirement Topics – Beneficiary
Direct Transfer or 60-Day Rollover
How you move the money matters as much as how much you move. There are two mechanics, and one carries meaningful risk.
Direct Trustee-to-Trustee Transfer
Your current custodian sends the money straight to the new Roth IRA custodian. You never touch the funds. Direct transfers are not subject to the once-per-year rollover restriction, so you can do as many as you need in a year.10Internal Revenue Service. Announcement 2014-15, Application of One-Per-Year Limit on IRA Rollovers There is no mandatory withholding, and no 60-day clock.
Indirect (60-Day) Rollover
The distributing institution sends the funds to you, and you have 60 days from the date of receipt to deposit them into the Roth IRA.11Internal Revenue Service. Topic No. 413, Rollovers From Retirement Plans Miss that window and the entire amount is treated as a taxable distribution, plus a 10% penalty if you are under 59½.
Indirect rollovers from an employer plan trigger mandatory 20% federal tax withholding.12eCFR. 26 CFR 31.3405(c)-1 – Withholding on Eligible Rollover Distributions If your 401(k) distributes $50,000, the plan withholds $10,000 and you receive a check for $40,000. To complete a full rollover of the original $50,000, you have to deposit the $40,000 plus $10,000 from your own pocket into the Roth IRA within 60 days.13Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions Deposit only the $40,000 you received, and the missing $10,000 becomes a taxable distribution. You claim the withheld $10,000 as a tax credit when you file.
Indirect IRA-to-IRA rollovers carry a second limit: one per any 12-month period, applied across all of your IRAs combined rather than per account.10Internal Revenue Service. Announcement 2014-15, Application of One-Per-Year Limit on IRA Rollovers Rollovers from an employer plan into an IRA are not subject to this restriction.
The IRS does allow waivers of the 60-day deadline for qualifying hardships under Revenue Procedure 2016-47, including financial institution error, a lost check, serious illness or death in the family, severe damage to your home, incarceration, and postal error. If a qualifying reason applies, you must complete the rollover within 30 days after the obstacle is gone.14Internal Revenue Service. Revenue Procedure 2016-47, Waiver of 60-Day Rollover Requirement
The 5-Year Clock on Converted Money
Once converted dollars land in your Roth IRA, a separate five-year period begins for those funds. Withdraw the taxable portion of a conversion before both five tax years have passed since that conversion and you have reached age 59½, and you owe a 10% penalty on the amount withdrawn.3Office of the Law Revision Counsel. 26 USC 408A – Roth IRAs Each conversion has its own clock. A 2026 conversion is timed separately from a 2027 conversion.15Internal Revenue Service. Publication 590-B, Distributions From Individual Retirement Arrangements
The ordering rules for Roth withdrawals soften the impact. The IRS treats distributions as coming out in this sequence:
- Regular annual contributions first, always tax- and penalty-free.
- Converted and rolled-over amounts next, on a first-in, first-out basis. Within a single conversion, the taxable portion comes out before the nontaxable portion.
- Earnings last.
You have to exhaust your regular contributions before touching conversion money.15Internal Revenue Service. Publication 590-B, Distributions From Individual Retirement Arrangements Several exceptions can waive the 10% penalty inside the five-year window, including permanent disability, death, a qualified first-time home purchase (up to $10,000), and certain unreimbursed medical expenses.16Internal Revenue Service. Topic No. 557, Additional Tax on Early Distributions From Traditional and Roth IRAs
Forms You Should See
A rollover generates a paper trail across three forms:
- Form 1099-R comes from the institution that distributed the funds. Box 1 shows the gross distribution; Box 7 carries a code identifying the transaction type. It is typically available by late January of the following year.17Internal Revenue Service. About Form 1099-R, Distributions From Pensions, Annuities, Retirement or Profit-Sharing Plans, IRAs, Insurance Contracts, Etc.
- Form 5498 comes from the receiving Roth IRA custodian. Box 2 reports rollover contributions and Box 3 reports conversion amounts. An initial version may arrive in January, but the final form is not due until June 1.18Internal Revenue Service. Form 5498 – IRA Contribution Information19Internal Revenue Service. 2025 Instructions for Forms 1099-R and 5498
- Form 8606 goes with your tax return to report the taxable and nontaxable portions of a conversion from a traditional IRA, and any nondeductible traditional IRA contributions.6Internal Revenue Service. Instructions for Form 8606
Check your Form 5498 carefully. The rollover or conversion has to be coded as such, not as a regular contribution. If your custodian miscodes it, the amount can be flagged as an excess contribution, which carries a 6% excise tax for every year it stays uncorrected.20Office of the Law Revision Counsel. 26 USC 4973 – Tax on Excess Contributions to Certain Tax-Favored Accounts and Annuities Contact the custodian promptly to fix any coding error.
