Cover image: Roth Conversions Explained in Plain English

A Roth conversion means moving money from a traditional IRA or similar pre-tax account into a Roth IRA. You pay income tax on the amount you move, in exchange for a different tax treatment later. It is a tool some people use, not a fit for everyone.

Key takeaways
  • You pay income tax on the converted amount in the year of the conversion
  • Qualified Roth withdrawals later are generally tax-free
  • A conversion adds to your income, which can affect other costs
  • Whether it makes sense depends on your own situation

How it works

Money in a traditional IRA has not been taxed yet. When you take it out, it is taxed as ordinary income. A Roth IRA is the opposite: you pay tax up front, and qualified withdrawals later are generally tax-free.

In a conversion, you choose an amount to move. That amount is added to your income for the year, and you pay tax on it.

Why people look at conversions

  • Tax brackets: Some people have a few years of lower income after they stop working and before required withdrawals begin. Converting during those years may let them use lower brackets.
  • Required withdrawals: Roth IRAs do not require withdrawals during the owner's lifetime. A smaller pre-tax balance can mean smaller required withdrawals later.
  • Heirs: Money left to heirs from a Roth account can be more flexible for them, though rules apply.

What to weigh first

A conversion raises your income for the year. That can have effects beyond the tax bill:

  1. It may push you into a higher tax bracket.
  2. It may increase the share of your Social Security benefit that is taxed.
  3. For people on or near Medicare, it may raise your Part B and Part D premiums two years later.

Where you get the money to pay the tax also matters. Many people prefer to pay it from savings outside the account rather than from the converted money.

Going in steps

Some people convert a smaller amount over several years rather than all at once. This can spread the tax over more than one year. Each year, the choice can be reviewed against your income and the tax rules at that time.

The bottom line

A Roth conversion is a planning choice with trade-offs. If you would like to see how it might look alongside your taxes and Medicare costs, let's talk.
