How it is worked out
The published maximum in full at or below the published phase-out threshold, nothing at or above the published amount where it is fully phased out, and in between the same share of the maximum as the share of the range your income has left to run. Rounded to the nearest cent.
It uses Exemption, married individuals filing separate returns, $70,100 and Exemption phaseout threshold, married individuals filing separate returns, $500,000 and Fully phased out, married individuals filing separate returns, $640,200, published above.
Figures in this colour are computed from the amounts above. They are not published figures and no document states them.
