The tax credit applies to work prescribed by the WITB. Pre-diagnostics expenses are also included.

The work must be carried out by the same company that supplies the equipment.

The work must be invoiced before 31 December 2023 inclusive.

You receive a tax credit equal to 40% the amount of the expenditure.

Spending between 2015 and 2023 is capped at €20,000 per unit. This limit applies regardless of the number of occupants in the dwelling.

You must report the amount of expenses you paid in 2021.

Keep receipts for expenses because the tax authority can ask for them (company invoice, seller's certificate).
