My wife and I will have $0 income for 2025 tax year, filing jointly in CA, and I'll be the only one doing the conversion.

    So standard deduction is $31,500 for 2025. And the federal rate is 10% for income $0-$23,850.

    So does that mean if I convert exactly $31,500, then I owe no federal and state tax?

    And if I were to, say, convert $55,350 (31,500+23,850), then I would owe $2385 federal (10% of $23,850) and about $239 state (1%)?

    And apply the same formula for higher tax brackets. So I'm trying to figure out how much I'm willing to pay extra to convert more than $31,500.

    Asides from corrections, any advice would be greatly appreciated! Thanks.

    1. You’re correct about federal.

      California has a smaller standard deduction, so you would owe state tax on most of the conversion.

      As for whether you should convert more beyond the 10% bracket, the question is how high you expect your tax rate to be in retirement.

      .

      `for 2024` << I assume this was a typo since you’re using 2025 numbers. To be clear: it’s far too late to do anything for 2024, and even though you can make a 2025 contribution through April 2026, a *conversion* counts for the year it actually happened.
