A Roth conversion moves funds from a traditional IRA or 401(k) into a Roth IRA, triggering immediate income taxes. For most retirees, this trade pays off through tax-free growth and withdrawals later. But six specific situations demand caution before converting.
First, avoid conversions during high-income years. If you expect business income, capital gains, or large bonuses, the conversion pushes you into a higher tax bracket. You pay more tax today with no offsetting benefit.
Second, conversions backfire if you're collecting Social Security. The additional income from a conversion increases your modified adjusted gross income (MAGI), which triggers taxation of up to 85% of your Social Security benefits. A $50,000 conversion could cost $30,000 in extra taxes when you factor in Social Security taxation.
Third, skip conversions if you're near Medicare enrollment. Higher MAGI from conversions directly impacts Medicare premiums (Income-Related Monthly Adjustment Amounts). A single conversion in 2024 could lock you into higher premiums for three years.
Fourth, don't convert if you'll need the money within five years. Roth conversions come with a five-year holding period on converted funds. Withdrawing early triggers penalties and taxes, erasing your advantage.
Fifth, conversions hurt if you qualify for need-based aid for a dependent's college expenses. The conversion counts as income, reducing financial aid eligibility for that year and the following year.
Sixth, be cautious if your state has income tax. States like California, New York, and Minnesota tax Roth conversions even though the federal government may not. A $100,000 conversion costs an additional $5,000 to $13,000 in state taxes depending on your location.
