Suma Gestión Tributaria (Suma) is a 100% public provincial agency set up by the Provincial Council of Alicante (Spain) in 1990. It specializes in tax administration: assessment, billing, collection and enforcement. Suma collects the taxes on behalf of each city council with own resources.

Its governing body is the Board of Suma, made up of the Executive Director, 7 to 11 Provincial Representatives and it is chaired by the President of the Provincial Council. There is, in addition, a consultative body, called the Council of Mayors, which guarantees the participation of the delegating Town Councils in the strategies adopted by Suma.

The name, Suma (meaning addition), seeks to express a concept of integration, accumulation, growth, and incorporation. In line with this name and the image of the two blue squares, it has developed a corporative culture based on the principle of greater service for the rate-payer and greater service for the municipality.
