From 1 January 2028, the standard corporate tax rate will drop to 17%, while SMEs in agriculture, commerce, or industry will pay 15% on the first EUR 50,000 of taxable income.

Portugal’s parliament has gazetted Law No. 64/2025 on 7 November 2025, reducing corporate income tax rates.

Under the new law, the standard corporate income tax (CIT) rate will decrease to 17% for tax periods commencing on or after 1 January 2028.

Small and medium-sized enterprises in the agricultural, commercial, or industrial sectors will benefit from a reduced 15% rate on the first EUR 50,000 of taxable income.

The legislation also includes transitory norms that set higher intermediate tax rates for the years 2026 (19%) and 2027 (18%) before the permanent 17% rate takes effect.

Earlier, Portugal presented its 2026 budget on 9 October 2025, proposing corporate tax cuts and relief for lower-income households.
