IRA Recharacterization Calculator
Calculate the exact transfer amount for a Traditional-to-Roth or Roth-to-Traditional IRA recharacterization using the official IRS NIA formula.
Enter the total amount you deposited into this IRA for the tax year selected.
Must be less than or equal to your total contribution. You can recharacterize any portion of your original contribution.
The date you made the contribution to the source IRA. Used to generate the required IRS written statement.
The IRS requires that earnings attributable to your contribution transfer along with it. The NIA formula allocates a proportional share of the account's investment performance to the contribution being recharacterized.
If the account gained value, you transfer more than the contribution. If it lost value, you transfer less. The NIA can never make the transfer amount negative — the minimum is $0.
The value of your IRA on the day before your first contribution of the tax year. If you made multiple contributions this year, always use the balance before the very first one — not the most recent.
The current value of your IRA today, plus any distributions taken since the contribution was made.

The IRS requires you to attach a written statement to your tax return explaining the recharacterization. Copy the statement below or include the text in your PDF.
Now that your funds are in a Traditional IRA as a non-deductible contribution, you may want to immediately convert them back to a Roth IRA. This completes the Backdoor Roth process.
Important: You must file Form 8606 to track your non-deductible basis. Without it, you may be taxed twice on this money when you withdraw it.
Important — Pro-Rata Rule: If you have any pre-tax money in any Traditional IRA, SEP IRA, or SIMPLE IRA, the conversion step of the Backdoor Roth will be partially taxable. The IRS treats all your traditional IRAs as one pool — you cannot convert only the after-tax portion. Our Pro-Rata Calculator will calculate your exact taxable amount.
