The quality or condition of being able to subtract money from your total income for tax purposes, or the ability to be deduced logically.
From 'deductible' (something that can be deducted) plus the noun suffix '-ity.' While 'deductible' has roots in Latin 'deducere,' its modern use was formalized in English legal and tax language during the 20th century.
The IRS popularized 'deductibility' as a tax term, but it has a double life: accountants and philosophers use almost the same word to mean different things—one about money, one about logic.
