Questions & Answers about Tu dois déduire ce montant du revenu imposable.

Why do we use du here instead of just de?

The verb déduire (to deduct) pairs with the preposition de to indicate where the amount is taken from. Because we are talking about a specific income, we need the masculine singular definite article le. The preposition de and the article le must contract to form du.

How does the word imposable relate to taxes?

Imposable means "taxable." It is built from the verb imposer (to tax or impose) and the suffix -able. You will often see it paired with revenu (income) in French administrative contexts to discuss taxes, which are called les impôts.

Could I use the verb soustraire instead of déduire here?

While soustraire (to subtract) is mathematically correct, déduire is the standard and most natural verb to use in accounting, tax, and administrative contexts when referring to financial deductions from a total amount.
