Question

How do I check my income-related monthly adjustment amount (IRMAA) threshold before doing a Roth conversion?

Answer

You can find the current brackets on the Social Security Administration’s IRMAA page. Your Medicare IRMAA surcharge is based on your modified adjusted gross income from two years prior; for 2026, the first threshold for joint filers is $218,000. A tax professional can help you model how a conversion might affect your premiums two years down the line.
