Finance: Iuc news in Portugal

New legislation published in the Diário da República authorizes the government to change the payment model for the Single Circulation Tax (Imposto Único de Circulação or IUC). Starting in 2027, the tax will move to a fixed payment schedule rather than being tied to a vehicle's registration month. The transition year of 2027 will feature single or split payments depending on the tax amount, with a permanent format taking effect in 2028.

The Official Journal (Diário da República) is Portugal's government gazette where laws, decrees and public contracts are formally published and take legal effect. Public‑private partnership approvals and other official notices — like the launch of the Central Algarve Hospital PPP — are published there so residents and businesses can find the authoritative text.
