Make Marriage Great Again Act of 2025

This bill changes federal income taxes so married couples don’t pay more tax just because they’re married. It sets the tax brackets for couples who file jointly to be exactly double the brackets for single filers, removing the so‑called “marriage penalty”. It also ends the special “married filing separately” brackets starting with 2025 tax years. The changes apply to tax years beginning after December 31, 2024.

In simple terms, if you file a joint return with your spouse, the income ranges taxed at each rate would be twice as large as for a single filer, which can lower your combined tax compared to today’s rules.

Key points

• Who is affected: Married couples, especially those filing jointly; people who currently file “married filing separately”.
• What changes: Joint brackets become double the single brackets; “married filing separately” brackets are removed.
• When: Starts with tax years after December 31, 2024 (the 2025 tax year and onward).
