How Do You Convert A Traditional IRA To A Roth IRA

A Roth IRA conversion involves requesting a direct transfer or rolling over funds from your traditional IRA into a Roth IRA. You will owe ordinary income tax on the pre-tax portion of the converted amount in the year you make the move. The process is straightforward, but the tax consequences require careful planning to avoid surprises. The mechanics, the tax bill you will face, and the situations where conversion might not be worth the cost all demand a clear-eyed look before you act.

The three ways to move the money in a Roth IRA conversion

The most reliable method is a direct trustee-to-trustee transfer. You instruct your traditional IRA custodian to send the funds directly to your Roth IRA custodian. The check is made payable to the Roth institution for your benefit. This avoids any withholding or tax penalty risk. If both accounts are at the same firm, you can often use a same-custodian internal conversion. This is typically a simple online form or phone request. Look for a "Convert to Roth" button in your account settings. The third option is the 60-day rollover rule. You withdraw the money from your traditional IRA and deposit it into your Roth IRA within 60 days. You report the rollover on your tax return. However, this method is risky because your custodian is required to withhold 10% for federal taxes, and possibly state taxes, on the withdrawal. If you fail to replace that withheld amount within 60 days, the shortfall counts as an early distribution. That distribution is subject to a 10% penalty if you are under 59½. The full landscape of these accounts lives at iras, the IRS hub for the rules governing every type of individual retirement arrangement. If you are also moving money from a former employer’s plan, the separate guide rollover pension to IRA explains how to consolidate those funds without triggering a surprise tax event.

What you'll actually owe in taxes

The IRS treats the converted amount as ordinary income in the year of conversion. The tax band you land in depends on your total taxable income for that year. If your top federal rate is 22% and you convert a sum that pushes your taxable income to the top of that bracket, the federal bill on a $50,000 conversion would be $11,000. These bracket thresholds are set annually by the IRS, and the current-year numbers live in the official tax rate schedules. If you have made non-deductible contributions to your traditional IRA, contributions you already paid tax on, the pro-rata rule applies. The taxable portion is based on the ratio of your pre-tax balance to your total IRA balances across all traditional IRAs. For example, if you have $80,000 in pre-tax funds and $20,000 in non-deductible contributions, only 80% of any conversion is taxable. Crucially, you cannot use the IRA funds themselves to pay the tax bill. If you are under 59½ and withdraw money from the IRA to pay the taxes, that withdrawal counts as an early distribution. It is subject to a 10% penalty on top of the income tax. You must pay the tax from outside savings, cash, a checking account, or other non-retirement funds. Also, be aware of the 5-year rule, a separate clock the IRS starts on each conversion. If you are under 59½, you cannot withdraw the converted principal from your Roth IRA for five years without incurring a 10% penalty, though the conversion itself is not penalized.

When converting is a bad idea

Converting during your peak earning years is often a mistake because your marginal tax rate is at its highest. The tax bill becomes larger than necessary. If you are in the 32% bracket, a $100,000 conversion could cost $32,000 in federal taxes, money that could otherwise grow tax-free. The 32% bracket is a tier set by the IRS, and the exact income range it covers changes each year. Similarly, if you lack the cash to pay the taxes separately, you should not convert. Dipping into the IRA to pay the tax triggers penalties and reduces your retirement savings. Another poor scenario is if you plan to move to a low-tax state soon. For example, converting while living in California, where the state’s top rate is 13.3%, and then moving to Texas, which has no state income tax, within a year means you pay state tax unnecessarily. Finally, if you expect to be in a lower tax bracket in retirement, say, because you will have less income, the upfront tax cost of conversion may never be recouped. In these cases, keeping your traditional IRA intact and paying taxes later at a lower rate is the smarter move.

Roth conversions succeed only when the tax cost is paid from cash sitting outside the retirement account. Every other strategy turns a tax-planning tool into a penalty trap.
