Standard deduction against itemising, 2025
This works out one number from the Standard Deduction figures published for 2025. Every amount it uses is below, with the document it was read from. What you enter is your own: this site has no way to check it, and the answer it produces is not a published figure.

How it is worked out
The published amount less the amount you enter, rounded to the nearest cent. Where what you enter is the larger of the two, the answer is nothing rather than a negative amount.
Your filing status, from the 3 this year publishes: Single unmarried ($15,750), Married jointly ($31,500), Head of household ($23,625). The calculator uses the one you pick and says which.
Figures in this colour are computed from the amounts above. They are not published figures and no document states them.
