What is a Roth conversion?

A Roth conversion is when you move money from a traditional IRA (or other pre-tax retirement account) into a Roth IRA. The converted amount is added to your taxable income in the year of the conversion, and you pay income tax on it now — in exchange for tax-free growth and tax-free qualified withdrawals going forward. This is financial education, not tax advice.

A Roth conversion is a taxable transaction: you take money that was contributed pre-tax (or grew tax-deferred) in a traditional IRA, SEP-IRA, SIMPLE IRA, or qualifying employer plan and move it into a Roth IRA. The IRS treats the converted amount as ordinary income in the year of conversion — you pay tax at your marginal rate now. In exchange, the money and its future growth come out tax-free in retirement (if you meet the qualified withdrawal rules). The IRS covers the rules in Publication 590-A and under Roth IRA conversions guidance.

When a Roth conversion can make financial sense

What makes a conversion potentially expensive

The converted amount stacks on top of your other income for the year. A large conversion could push you into a higher tax bracket, increase Medicare IRMAA surcharges (which are based on MAGI two years prior), phase out certain deductions, or trigger the net investment income tax. Partial conversions — converting a carefully sized portion each year — are often more tax-efficient than a single large conversion. Pay the tax from non-IRA funds if possible; using IRA funds to cover the tax bill reduces the benefit of converting.

The 5-year rule

Each Roth conversion starts its own 5-year holding period. To access converted funds penalty-free (if under age 59½), they must have been in the Roth IRA for at least 5 years. Note this is separate from the 5-year rule that governs qualified earnings distributions from a Roth IRA overall. The IRS addresses this in Publication 590-B — the interaction of the two 5-year rules is a common source of confusion.

Roth conversions require careful tax planning — consult a CPA

A poorly timed Roth conversion can push you into a higher bracket, trigger IRMAA surcharges, or create an unnecessary tax bill.

Before executing a Roth conversion — especially a large one — work with a CPA or CFP who can model the year-by-year tax impact.
