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 Head of household, $23,625 and Aged blind addition unmarried, +$2,000, published above.

Figures in this colour are computed from the amounts above. They are not published figures and no document states them.
