Imponible

Imponible is a term used in tax law to describe income, assets, or transactions that are subject to taxation. In Spanish-speaking jurisdictions the adjective typically refers to the tax base—the amount against which the applicable tax rate is applied. The concept is used in a variety of taxes, including income tax, corporate tax, value-added tax (VAT), capital gains, and property taxes.

base imponible refers to the tax base itself, the quantity from which the tax is calculated after accounting for deductions, exemptions, or reductions provided by law. The base imponible may differ depending on the tax context. For example, in personal income tax it often equals net income after allowable deductions; in VAT it corresponds to the price of the goods or services, sometimes excluding certain costs or including them depending on the jurisdiction’s rules.

Calculation and examples help illustrate the idea. If a product is sold for 100 units of currency and the VAT rate is 21%, the base imponible is typically 100, and the tax due would be 21. If discounts are applied, reducing the price to 95, the base imponible becomes 95, and the VAT due would be 19.95, subject to how the law treats discounts and rebates.

Imponible is distinct from the actual tax payable (the amount due after applying rates to the base) and from exemptions or credits that may further reduce the final liability. The term emphasizes what part of a financial amount is eligible to bear tax under the applicable legal framework.
