CALCULATOR
Widow's Penalty Calculator (2026)
When one spouse dies, the survivor stops filing jointly and files Single — where the 2026 federal tax brackets are roughly half as wide. The same pension, Social Security, and RMD income suddenly lands in a higher bracket, and it stays there every year for the rest of their life. That is the widow's penalty. This calculator estimates the extra federal tax a surviving spouse would owe on the same taxable income, using the source-verified 2026 federal brackets — the same math in The 30-Day Roth Accelerator Handbook. Knowing the number is the first step to shrinking it while both spouses are still alive to file jointly.

What is the widow's penalty?
When one spouse dies, the survivor stops filing jointly and files Single, where the 2026 federal brackets are roughly half as wide. The same pension, Social Security, and RMD income lands in a higher bracket — and stays there every year afterward. That extra lifetime tax is the widow's penalty.
