Frequently asked questions
A clear starting point. For a binding answer, always use the official simulator and government information.
For applications from March 1, 2026, support for windows and doors lies with owner-occupiers from income categories 3 and 4 and with landlords to a housing company. From that date, owner-occupiers from categories 1 and 2 and other investors will no longer receive a premium for this category. The home and the works must also meet the technical conditions.
According to the Flemish conditions for applications in 2026, category 4 can receive up to 50% of the investment excluding VAT, with a maximum of 5,250 euros. For category 3 this is up to 35%, with a maximum of 3,675 euros. The official counter determines the final amount.
This is possible in certain renovations, but both schemes have their own conditions. A home that is at least 10 years old that is mainly used privately after the works can be eligible for 6% VAT under certain conditions. Check your specific situation with Flanders and the FPS Finance.
