How it works

The Roth Conversion Tax Planner helps you determine the tax implications of converting funds from a traditional IRA to a Roth IRA. By inputting your traditional IRA balance, current tax rate, expected retirement tax rate, the amount you wish to convert, and your years until retirement, the calculator provides insights into the tax cost of the conversion, potential lifetime tax savings, and the impact on your tax bracket. For instance, if you have a traditional IRA balance of $500,000 and decide to convert $50,000 at a current tax rate of 22%, you would incur a tax cost of $11,000 from the conversion. However, if your retirement tax rate is expected to be 15%, the lifetime tax savings can be significant, as future withdrawals from the Roth IRA would be tax-free. This tool allows you to evaluate the benefits of converting now versus later, helping you make informed decisions about your retirement strategy.

Tips

  • Consider your current and future tax rates; if you expect to be in a higher tax bracket during retirement, a Roth conversion may be more beneficial.
  • Plan conversions in years with lower income to minimize the tax impact; this could save you money in the long run.
  • Use the calculator to model different conversion amounts to see how they affect your tax bracket and overall tax liability.
  • Keep track of your conversion amounts annually to avoid exceeding IRS limits and to optimize your tax strategy.
