Roth conversions are not going away in 2026. They remain fully legal under current federal law, with no income limit and no cap on how much you can convert in a single year. Proposals to restrict conversions for high earners came close to passing in 2021 but never became law, and no similar restrictions have advanced through Congress since.
What the Law Says Right Now
Internal Revenue Code Section 408A governs Roth IRAs and their conversion rules. Any taxpayer with money in a traditional IRA, SEP IRA, SIMPLE IRA, or employer plan can move those funds into a Roth account by paying ordinary income tax on the pre-tax portion of the transfer.1Office of the Law Revision Counsel. 26 USC 408A – Roth IRAs There is no dollar ceiling, and you can convert multiple times in the same year.
This open access is relatively recent. Before 2010, only taxpayers with adjusted gross income below $100,000 could convert. The Tax Increase Prevention and Reconciliation Act of 2005 eliminated that income threshold for tax years beginning after December 31, 2009.2United States Senate Committee On Finance. Background on the Roth IRA Conversion Proposal in Tax Reconciliation Bill Since then, anyone with a qualifying account balance can convert regardless of filing status or earnings.
Conversion rules sit apart from Roth IRA contribution rules, which is worth keeping straight. For 2026, direct Roth IRA contributions are capped at $7,500, and the ability to contribute phases out between $153,000 and $168,000 of modified AGI for single filers ($242,000 to $252,000 for married filing jointly).3Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Conversions bypass those limits entirely, which is exactly why they attract legislative attention.
The 2021 Proposals That Almost Passed
The most serious attempt to limit Roth conversions came in 2021 as part of the Build Back Better Act framework. The bill passed the House but stalled in the Senate, and it contained two restrictions squarely aimed at high earners:
- An income-based conversion ban prohibiting single filers earning over $400,000 and married couples filing jointly above $450,000 from converting any pre-tax funds to a Roth account.
- A ban on converting after-tax (non-deductible) contributions in both IRAs and employer plans, which would have effectively ended the backdoor Roth IRA and the mega backdoor Roth strategies regardless of income.
Supporters argued that letting wealthy taxpayers shelter millions in tax-free Roth accounts costs the government significant future revenue. Neither provision became law. As of mid-2026, no similar restrictions have been enacted or advanced through committee in subsequent sessions, including the recent reconciliation process.
The fact that these ideas came close once means some version could resurface. Retirement policy is a recurring revenue target. Nobody can reliably predict what a future Congress will do, so treating the current rules as permanent is not the same as treating them as guaranteed.
What Recent Laws Actually Changed
Two recent laws touch Roth accounts without restricting conversions, and it’s easy to confuse them with the ban that never happened.
The SECURE 2.0 Act of 2022 requires that certain catch-up contributions to employer plans be made on a Roth basis rather than pre-tax. Starting with tax years beginning after December 31, 2023, employees whose prior-year FICA wages exceed $145,000 must direct their catch-up contributions to the Roth side of the plan. That threshold is indexed for inflation; for the requirement measured against 2026 wages, the figure is $155,000.4Federal Register. Catch-Up Contributions This is a mandate pushing high earners toward Roth treatment, not a limit on conversions.
The One Big Beautiful Bill signed in 2025 modified individual income tax rates that had been set to expire at the end of that year. Rate changes don’t alter conversion rules, but they change the math. Lower rates make a conversion cheaper; higher rates make it more expensive. The rate environment is a planning input, not a legal barrier.
Backdoor and Mega Backdoor Strategies Are Still Legal
Both strategies specifically targeted in 2021 remain available.
The backdoor Roth IRA involves making a non-deductible contribution to a traditional IRA and then converting it to a Roth. Because the contribution was already taxed, the conversion itself generates little or no additional tax liability, assuming you have no other pre-tax IRA balances. This lets high earners who exceed the Roth contribution phase-out get money into a Roth anyway.
The mega backdoor Roth runs through employer plans that allow after-tax contributions beyond the standard elective deferral limit. For 2026, the total annual additions limit for defined contribution plans is $72,000, while the elective deferral limit is $24,500.5Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs, as Adjusted The gap between those two numbers, up to $47,500 for someone under 50, can potentially be routed into a Roth account if the plan permits after-tax contributions and either in-plan Roth conversions or in-service distributions. Not every employer plan offers the feature.
Lawmakers have described both strategies as loopholes that circumvent Roth contribution limits. Whether they survive future sessions is genuinely uncertain. Today they remain available to anyone whose plan or account structure supports them.
The Deadline and the No-Undo Rule
A conversion must be completed by December 31 to count for that tax year. This is different from IRA contributions, which can be made up to the April filing deadline. If you’re planning a conversion for a given year, the funds need to move before the calendar year closes. The conversion is reported on Form 8606 with your return for that year.6Internal Revenue Service. Instructions for Form 8606
Once you convert, you’re locked in. Before 2018, if a conversion turned sour — the account dropped in value right after you moved the money, or your income came in higher than you expected — you could recharacterize the conversion back to a traditional IRA and undo the tax hit. The Tax Cuts and Jobs Act eliminated recharacterization permanently for conversions starting in 2018.
That makes conversion planning higher stakes than it used to be. You need reasonable confidence about your income for the year, your bracket, and your ability to pay the resulting tax bill, ideally from funds outside the retirement account, before you pull the trigger. There is no take-back if the market drops the next quarter.
Accounts That Can’t Convert Freely
A few situations sit outside the general “anyone can convert” rule, and they surprise people mid-process.
Non-spouse beneficiaries who inherit a traditional IRA cannot convert those funds to a Roth IRA. The IRS rules for non-spouse beneficiaries provide for life-expectancy-based distributions or the 10-year rule, but conversion is not among the options.7Internal Revenue Service. Retirement Topics – Beneficiary Surviving spouses generally have more flexibility; they can elect to treat the inherited IRA as their own and then convert under normal rules.
If you participate in a SIMPLE IRA, you must wait two years from the date of your first contribution before converting to a Roth IRA. Converting before that window closes triggers a 25% early distribution penalty on top of regular income tax on the conversion.8Internal Revenue Service. Retirement Plans FAQs Regarding IRAs After the two-year period, a SIMPLE IRA converts under the same rules as any other traditional IRA.
The Bottom Line for 2026
Roth conversions are legal, uncapped, and open to any income level, and no restriction is currently moving through Congress. The window is as open as it has been since 2010. The rules that changed recently push more high-earner contributions toward Roth treatment; they do not close the conversion door. People who convert this year should focus on the December 31 deadline, the fact that the decision is permanent, and their own tax picture rather than on rumors of a coming ban.
