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.
One educator, or two filing jointly, from the 2 this year publishes: Maximum deduction ($300), Maximum deduction on a joint return when both spouses are eligible educators ($600). 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.
