4. Income Tax Reduction - The Tax Saving
What Is the Income Tax Reduction?
Personal Income Tax = Your Regular Tax
Income Tax Reduction = You Can Deduct Part of Your Renovation Costs
How It Works (Belgian System):
MAXIMUM DEDUCTION:
- €3,300 per Year (Labour Costs)
- This Is the Maximum Deductible Labour Cost per Year
TAX BENEFIT:
- You Pay 30% Income Tax on Your Regular Earnings
- If You Deduct €3,300, You Save: €3,300 × 30% = €990/Year
DURATION:
- You Can Claim This for 5 Years!
- €3,300 × 5 = €16,500 in Total
- Saving: €16,500 × 30% = €4,950 over 5 Years!
Example: Energy Renovation
You Do Insulation + Windows:
- Painter's Wages: €1,500
- Electrician: €800
- Insulation Worker: €1,500
- TOTAL Labour Costs: €3,800
BUT:
- Maximum Deduction/Year: €3,300
- You Can Deduct the Remaining €500 the Following Year
SAVING over 5 Years:
- Years 1-5: €3,300 × 5 = €16,500
- Benefit at 30% Rate: €4,950 Tax Saving
5. Material Costs - More Complex!

Frequently asked questions
Which renovation costs are tax deductible in Belgium?
Labour costs (wages paid to tradespeople) for energy renovations, hygiene and safety work are deductible. This includes insulation, double glazing, heating, electrical work, damp repair and asbestos removal. Materials are generally not deductible, except in certain regional energy programmes.
How much can I save per year with the renovation tax deduction?
The maximum deductible labour cost is 3,300 euros per year. At a 30% income tax rate, this gives a maximum saving of 990 euros per year, and up to 4,950 euros over 5 years.
What happens if my labour costs exceed the annual maximum of 3,300 euros?
Any amount above 3,300 euros can be carried over and deducted the following year. The deduction can be spread over a period of up to 5 years.
Do I need to pay by bank transfer to claim the deduction?
Yes, payment by bank transfer or card is required because the tax authorities need official proof of payment. Cash payments are not accepted and will disqualify you from claiming the deduction.
What renovations are NOT tax deductible?
Maintenance work, ordinary painting, decoration, wallpaper, carpet, furniture, built-in kitchens and luxury upgrades like swimming pools and jacuzzis are not deductible. The rule is that if the home is not permanently improved, the work is considered maintenance and cannot be deducted.
