Compare US federal tax filing jointly with filing as two single taxpayers.
Spouses earning $150,000 and $50,000 pay less tax filing jointly: a marriage bonus of $2,214.00 using 2026 federal brackets.
Getting married can raise or lower your federal income tax depending on how incomes compare. Enter each spouse's income and the calculator computes the tax as two single filers and as a married couple filing jointly using the 2026 standard deductions ($16,100 single, $32,200 joint) and tax brackets.
Couples with very different incomes usually get a bonus; two high, similar incomes can face a penalty at the top brackets. Credits, itemised deductions and state taxes can change the result. See also the Income Tax Calculator and the Estate Tax Calculator.

When a married couple pays more tax filing jointly than they would as two single people.
When a couple pays less filing jointly, which usually happens if one spouse earns much more than the other.
The IRS 2026 brackets and standard deductions: 10% to $12,400 single ($24,800 joint), up to 37% above $640,600 single ($768,700 joint).
Above the 35% bracket the joint thresholds are less than twice the single ones, so two high earners are pushed into higher rates sooner.
