Tax benefit for renovating a rental property in Belgium
Are renovation works on a rented property tax-deductible in Belgium? Regional grants, tax deductibility, reduced VAT, and impact on EPC.
Deductibility of renovation works
The deductibility of works depends on the type of tenant and the type of works:
| Type of works | Rented to an individual | Rented to a company |
|---|---|---|
| Maintenance (painting, joints, minor repairs) | RC flat rate | Deductible (actual costs) |
| Repair (plumbing, electricity, roof) | RC flat rate | Deductible (actual costs) |
| Improvement (new kitchen, extension) | No | No (capitalised) |
| EPC (insulation, windows, heating) | RC flat rate | Deductible (if maintenance/repair) |
Maintenance vs improvement distinction
The boundary is sometimes blurred. The criterion: does the work restore the original condition (maintenance) or improve the property beyond its original state (improvement)?
Even if the works are not deductible (property rented to an individual), keep all invoices. They are useful for calculating the capital gain in case of sale before 5 years (documented works reduce the taxable capital gain).
Reduced 6% VAT on renovation
Conditions
The reduced 6% VAT (instead of 21%) applies if:
- The dwelling is more than 10 years old (15 years in Flanders for certain works since 2024)
- The works are renovation (not new construction)
- The dwelling is intended for housing (not purely commercial use)
- The works are carried out by a Belgian VAT-registered contractor
Works concerned
| Works at 6% | Works at 21% |
|---|---|
| Insulation (roof, walls, floors) | New construction |
| Window replacement | Extension exceeding 50% of the area |
| Electrical renovation | Pool, jacuzzi |
| Plumbing renovation | External landscaping (terrace, driveway) |
| Heating replacement | Solar panels (21% but subsidies available) |
| Painting, coverings | |
| Kitchen, bathroom |
Impact for the landlord
The 6% VAT applies even for a rented property. The landlord benefits from the reduced rate for renovation works on their rental property. The saving: 15% of the pre-tax amount of the works.
Example: works of 20,000 EUR pre-tax
- 21% VAT: 4,200 EUR — total 24,200 EUR
- 6% VAT: 1,200 EUR — total 21,200 EUR
- Saving: 3,000 EUR

Tax-optimised renovation strategy
Priority 1: improve the EPC
EPC works have a triple advantage:
- Regional subsidies (30-50% of cost)
- 6% VAT (15% saving)
- Unlock indexation (Brussels: EPC E-G = no indexation)
Priority 2: maintenance works (if rented to a company)
Maintenance works are deductible as actual costs. Plan them in the years when your income is highest (deduction at the highest marginal rate).
Priority 3: document for capital gains
Even if the works are not deductible, keep the invoices. In case of sale before 5 years, they reduce the taxable capital gain.
