How much do you save with 3% VAT?
Verified on 17 October 2026.
On a window replacement, moving from the standard VAT rate to 3% makes a real difference. The total benefit is capped per home.
3% VAT explained simply
In Luxembourg, the state applies a reduced VAT rate to renovation work on homes. You do not claim it back later: once the application is approved, the company invoices you directly at the reduced rate.
The conditions
- A home more than 10 years old, or renovation within 5 years of buying it.
- A main residence, lived in by the owner or by a tenant.
- A cap of €50,000 of VAT benefit per home.
- An application before the work starts, made jointly by the company and the owner.
- A quote of at least €3,000 excluding VAT for the direct procedure.
- Windows and doors are among the eligible works.
These conditions are summarised for information only, subject to eligibility. Only the administration’s decision is binding: see the official page of the Registration Duties, Estates and VAT Authority.
How we help
- Measurement visit and detailed quote, with the applicable VAT clearly shown.
- Preparing the 3% VAT application with you, before the work starts.
- Invoicing at the reduced rate once approval is granted.
