Standard deduction against itemising for a single filer, 2024
This works out one number from the Standard Deduction figures published for 2024. 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.
This calculates
The standard deduction including the counted age-or-blindness additions, compared with the itemised deductions you enter.
You provide
- Your itemised deductions
- Boxes you can check for 65 or older, or blind (up to 2)
It does not include
- Whether you may claim the standard deduction, every itemised deduction rule, or a complete return.
Not the one you need? The same year also has standard deduction against itemising on a joint return, head of household standard deduction against itemising.

How it is worked out
The published limit, plus the published addition once for every box you check, 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.
It uses Single unmarried, $14,600 and Aged blind addition unmarried, +$1,950, published above.
Figures in this colour are computed from the amounts above. They are not published figures and no document states them.
