Using the Marriage Tax Calculator
Enter each partner’s ordinary income separately. A large gap between those incomes can produce a different comparison from two similar incomes, even when the household total is the same.

Match the tax year and scope
Tax estimates depend on the year, jurisdiction and definitions used in the model. Check whether an input means gross income, taxable income or an amount after a particular deduction. Keep excluded credits, other taxes and special circumstances separate. A simplified scenario can explain a relationship without reproducing the amount on an actual return.
Common question
Does a positive savings result guarantee a lower tax bill after marriage?
No. Credits, deductions, investment income and other circumstances can change the outcome. The result only compares the limited federal ordinary-income model described here.
