Portugal's Corporate Tax Cuts Are Good News, Except for Some American-Owned Businesses

Portugal has been lowering its corporate tax rate for several years, from 21% before 2025 to 20% that year, with a newer law bringing it to 19% in 2026, 18% in 2027, and 17% in 2028. For most businesses, that's a straightforward win, and one more reason Portugal has become an attractive place to set up shop for founders from all over the world.
