As 2025 comes to an end, understanding your property tax obligations Luxembourg becomes essential for anyone involved in real estate—whether you rent, own your main residence, hold multiple properties, or generate rental income. The tax landscape for property has evolved with recent legislative changes, and 2026 brings new considerations for compliance and planning.
This article provides a high-level summary of tax obligations across different real estate situations. For precise calculations, exemptions, and filing requirements, always consult the official information on Guichet.lu or a qualified tax advisor.
1. Tenants: Limited Direct Tax Impact
Tax situation:
Tenants in Luxembourg generally have minimal tax obligations beyond their standard income tax. Rent paid to landlords is not tax-deductible for tenants (unlike mortgage interest for owners).
What tenants should know:
- You are not responsible for property tax (taxe foncière)—this is paid by the property owner.
- Service charges (charges locatives) you pay for building maintenance, heating, or common areas are not tax-deductible.
- If you receive housing subsidies (aide au logement), these are typically not taxable income.
Key takeaway: Tenants face no direct property-related tax obligations; rental payments have no tax impact on your filing.
2. Main Residence Owners: Maximum Tax Advantages
Tax situation:
Understanding property tax obligations Luxembourg for your main residence is crucial because owner-occupiers benefit from the most tax-efficient treatment in the system.
Annual property tax (taxe foncière):
- The primary obligation for all owners is the annual taxe foncière, calculated on the cadastral “unitary value” of the property.
- Rates vary by municipality; urban areas like Luxembourg City typically charge higher rates.
- The owner as of January 1 each year is liable for the full year’s tax.
- From 2026, a new land tax framework (IMOB) will technically apply, though the rate remains at 0% for the first five years, meaning no immediate additional burden.
Mortgage interest deduction:
- Interest paid on loans to acquire, construct, or renovate your main residence is tax-deductible up to certain limits (currently €2,000 per person per year, or €4,000 for couples).
Capital gains tax exemption:
- When you sell your main residence, any capital gain is fully exempt from tax, regardless of how long you’ve owned it.
- This exemption significantly reduces tax burdens for homeowners.
Purchase tax benefits:
- When buying a main residence, you benefit from a 50% reduction in the taxable base for registration and transcription duties, reducing upfront costs.
Key takeaway: Main residence owners enjoy the lightest tax burden—deductible mortgage interest, no capital gains tax on sale, and reduced purchase taxes.
3. Multiple Property Owners (Not Rented): Holding Costs and Future Implications
Tax situation:
Owners holding multiple properties that are neither their main residence nor rented out face annual taxes on each property, with additional obligations from 2026 onward.
Annual property tax:
- Each property you own is subject to taxe foncière, regardless of whether you occupy it, rent it, or leave it vacant.
Unoccupied housing tax (from 2026):
- From January 2026, property tax obligations Luxembourg expand to include a tax on unoccupied housing.
- A dwelling is considered “unoccupied” if no natural person is registered there for 6 consecutive months.
- This new measure increases obligations for owners of vacant properties.
Capital gains tax on sale:
Understanding tax implications when selling investment properties is critical:
- Held less than 5 years (as of 2025): capital gains taxed at full progressive income tax rates (up to 45.78% including surcharges).
- Held more than 5 years: capital gains taxed at approximately 22.89% (half the marginal rate), with a €50,000 exemption (€100,000 for couples).
- Special temporary measure expired September 30, 2025: properties held over 2 years previously enjoyed a quarter rate (11.45%), but this benefit has now ended.
Key takeaway: Multiple property ownership creates substantial ongoing costs through annual property tax, new unoccupied housing taxes from 2026, and significant capital gains taxation unless held over 5 years.
4. Landlords: Rental Income Taxation and Compliance
Tax situation:
Landlords face the most complex property tax obligations Luxembourg because rental income is fully taxable, requiring careful annual declaration and expense tracking.
Declaring rental income:
- A key obligation for landlords is declaring all rental income annually using Form 210 (Déclaration pour la location de biens immobiliers).
- This applies to Luxembourg residents renting properties in Luxembourg or abroad, and to non-residents renting properties in Luxembourg.
Calculating taxable rental income:
Taxable income = Gross rent received – Deductible expenses
Deductible expenses that reduce tax burden:
- Flat-rate deduction: 35% of gross rental income, up to a maximum of €2,700 per year per property. This automatic deduction helps lower your tax liability.
- Additional deductible expenses (beyond the flat-rate):
- Mortgage interest on loans used to acquire or renovate the rental property
- Property tax (taxe foncière)
- Insurance premiums
- Maintenance and repair costs
- Depreciation (amortissement) on the building
- Property management fees
- Legal and administrative costs
Tax rate:
- Net rental income is added to your other income and taxed at your progressive income tax rate (which can reach up to 45.78% including solidarity surcharge).
Purchase tax benefits for rental investment:
- When purchasing a property intended as a tenant’s main residence, you may benefit from a 50% reduction in the taxable base for registration duties.
Capital gains tax on sale of rental property:
- Same rules as investment properties: holding period determines tax rate, with the 5-year threshold being critical for reduced taxation.
Key takeaway: Landlords face substantial obligations through rental income taxation, but benefit from generous deductions (35% flat-rate plus actual expenses). Proper record-keeping is essential.
5. Investors and Developers: Specialized Tax Treatment
Tax situation:
Professional property investors and developers face specialized property tax obligations Luxembourg beyond standard ownership taxation.
Speculative transactions:
- Frequent buying and selling may trigger classification as professional activity, fundamentally changing your tax treatment from capital gains to higher business income taxation.
VAT on property sales:
- Most residential property sales by private individuals are exempt from VAT.
- New construction or substantially renovated properties sold by developers within 2 years of completion may be subject to 17% VAT.
Corporate ownership:
- Properties held through Luxembourg companies face different tax regimes, including potential wealth tax, corporate income tax, and specific capital gains treatment.
Key takeaway: Professional-scale activity creates complex obligations requiring specialized tax planning and often corporate structuring.
6. Inheritance and Gifts: Transfer Tax Implications
Tax situation:
Understanding property tax obligations Luxembourg for property transfers through inheritance or gift is essential for succession planning.
Inheritance tax (droits de succession):
- Tax on inherited property varies significantly based on relationship:
Gift tax (droits de donation):
- Gifting property during your lifetime triggers gift tax at similar rates to inheritance tax.
Capital gains on inherited property:
- When you inherit property and later sell it, capital gains are calculated from the original owner’s purchase date, not from inheritance date.
Key takeaway: Succession planning should carefully analyze tax implications to minimize transfer costs for heirs.
7. Compliance and Deadlines for 2026
Annual tax return:
- Tax returns for 2025 income must be filed by March 31, 2026 (paper) or June 30, 2026 (electronic).
Property tax (taxe foncière):
- Typically due in quarterly installments throughout the year.
Reporting property sales:
Record-keeping requirements:
- Landlords: maintain detailed records of all rental income and expenses for at least 10 years.
- All owners: keep purchase documents, improvement receipts, and notarial deeds for capital gains calculations.
