“Line D minus Line E (if Line D is less than Line E, then Line F is $0)”
Formula
× 80% or × 75% when not deductible
When maintenance isn’t tax-deductible for the payer (the federal rule for orders since 2019), the result is multiplied by 80% if combined monthly income is $10,000 or less, or 75% from $10,001 to $20,000.[1]
