"Does getting married affect my taxes?" The honest answer is: it depends entirely on how your two incomes compare to each other — not on marriage itself.
Marriage penalty calculator, when similar incomes get punished
Two spouses each earning $90,000 would owe $10,970 apiece filing single — $21,940 combined. Filing jointly at a combined $180,000, the 2026 married brackets (which are exactly double the single brackets at these levels) produce the identical $21,940. No penalty, no bonus — just parity, because the brackets were built to double evenly here.

The picture changes with unequal earners. One spouse at $150,000 and another at $20,000 would owe $25,124 combined if both filed single. Filing jointly on the same $170,000 combined income drops the tax to $19,740 — a $5,384 marriage bonus, because the lower earner's income gets taxed at the wider joint bracket's lower rates instead of stacking on top of the higher earner's bracket.
Married filing jointly vs single calculator, why this varies by couple
There's no universal answer — the outcome depends on the ratio between the two incomes and where they fall relative to the bracket thresholds. Couples with similar incomes near certain bracket boundaries can see a real penalty; couples with very different incomes usually see a bonus. Running your own numbers is the only way to know which applies to you.
