If your renovation works cost €50,000, VAT at 3% instead of 17% saves you €7,000 directly.
Reduced VAT 3% is one of the most underestimated benefits in Luxembourg. Unlike Klimabonus which requires a complex online application, the 3% VAT applies directly to your invoice—if you meet a few simple conditions.
This guide explains exactly who qualifies, which works are eligible, and how to maximise your savings.
3% VAT: How much do you actually save?
Standard VAT in Luxembourg: 17% Reduced renovation VAT: 3%
| Work budget | VAT at 17% | VAT at 3% | Savings |
|---|---|---|---|
| €10,000 | €1,700 | €300 | €1,400 |
| €20,000 | €3,400 | €600 | €2,800 |
| €30,000 | €5,100 | €900 | €4,200 |
| €50,000 | €8,500 | €1,500 | €7,000 |
| €100,000 | €17,000 | €3,000 | €14,000 |
Annual cap: Reduced VAT applies up to €50,000 of work per calendar year. Beyond that, VAT reverts to 17%.
Concrete example: Bathroom renovation (€18,000) + living room painting (€3,000) = €21,000 in 2025 → You save €2,800 with reduced VAT.

You’re eligible if you meet these two conditions:
✅ 1. Owner or authorised tenant
- Owner-occupied: Yes
- Landlord: Yes
- Tenant: Yes, if you have written consent from owner

✅ 2. Existing building over 20 years old
- House built before 2005: Yes
- House built 2005 or later: No

|---|---|---|---|
| Air-to-water heat pump | €12,000 | €2,040 | €14,040 |
| Wall insulation 50m² | €10,000 | €1,700 | €11,700 |
| Total with 17% VAT | €22,000 | €3,740 | €25,740 |

- With 3% VAT + Klimabonus: €11,660
- Total savings: €14,080 (55% of cost!)
How to get 3% VAT?
Unlike Klimabonus, no administrative application needed. Here’s the simple process:
Before signing with contractor
1. Check building age Ask your commune or check your property deed. If building over 20 years old, you qualify.
2. Tell your contractor Say: “I’m eligible for 3% VAT on this renovation”
A good Luxembourg contractor knows these conditions. If they say “I don’t know what that is”, that’s a red flag.
3. Request a detailed quotation:
- Eligible vs non-eligible works (clearly separated)
- Net price (before tax)
- VAT applied (3% or 17%)
- Final price including VAT
On the invoice
4. Check the final invoice VAT applied must be 3% if all works are eligible.
Correct invoice looks like:
Bathroom renovation works
- Tiling installation (eligible 3% VAT): €5,000 net
- Plumbing (eligible 3% VAT): €3,000 net
- Labour (eligible 3% VAT): €2,000 net
Net subtotal: €10,000
VAT 3%: €300
TOTAL: €10,300 5. Keep:
- Signed quotation
- Final invoice
- Payment proof
- Before/after photos
In case of tax audit (rare), authorities may request documentation. Having clear records protects you.
Common mistakes that lose 3% VAT
❌ Mistake 1: Supplying materials yourself If you buy tiles/paint and give them to the contractor to install, only the installation may be 3% VAT, but materials stay at 17%.
Better: Ask the contractor to supply materials. Slightly higher cost but 3% VAT on everything.
❌ Mistake 2: Mixing eligible and non-eligible works without separation If invoice combines painting (eligible) + appliance (non-eligible) without distinction, authorities may refuse 3% VAT on everything.
Solution: Two separate invoices, or clearly separated net/VAT.
❌ Mistake 3: Forgetting the 20+ year rule A 2005 house is not eligible in 2025 (it’s exactly 20 years old). Check the permit date carefully.
❌ Mistake 4: Requesting 3% VAT after invoice Once invoiced at 17% VAT, you can’t change it retroactively. Clarify BEFORE signing.
Common questions about 3% VAT
Q: Can I get multiple quotations with 3% VAT to compare? A: Yes, recommended. Verify all quotes properly detail 3% VAT on eligible works.
Q: If I exceed €50,000 per year, when does 3% VAT stop? A: 3% VAT applies up to €50,000 per calendar year (1 Jan-31 Dec). Beyond that, VAT reverts to 17% on excess.
Example: €55,000 works = €50,000 at 3% + €5,000 at 17%.
Q: Can I apply 3% VAT to a second home? A: Yes, if it meets conditions (over 20 years). 3% VAT doesn’t distinguish primary vs secondary residence.
Q: Holiday rental (Airbnb, guesthouse): Does 3% VAT apply? A: Yes, if property over 20 years. Holiday rental is always considered property improvement.
Conclusion: €7,000+ you shouldn’t miss
3% VAT is simply free money if you meet two conditions:
- Property over 20 years ✓
- Eligible works ✓
No bureaucratic forms, no delays, no approval needed. Just correctly issued invoices.
On a €50,000 renovation budget, 3% vs 17% VAT = €7,000 in direct savings.
Final advice: Before contacting a contractor, check your property’s construction year. If over 20 years, mention 3% VAT in your inquiry. Good contractors know how to handle this without issue.
