How a deduction differs from a credit

A deduction shrinks the amount being taxed, while a credit subtracts from the tax after that amount is set.

From the opening

A deduction is an amount the statute lets someone subtract while computing the tax base, so less of that base is left for the rate to meet. A credit is an amount subtracted from the tax itself after the rate has already been applied, which is a later and different step in the same computation. The opening covers deductions act before the rate, credits act on the tax, and exclusions never enter the base.

The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
