Luxembourg Property Taxes Explained for Buyers and Investors (2026)

If you ask ten Luxembourg property buyers to explain how the country's real estate taxes work, you will get ten different — and mostly partial — answers. The Luxembourg property tax system is precise, but it has several layers that interact in non-obvious ways. Registration tax. Bëllegen Akt credit. Annual property tax (impôt foncier). Capital gains tax on resale. Rental income taxation. VAT mechanics on new-build purchases. Each of these is straightforward in isolation, but the cumulative picture across a full ownership life cycle confuses even experienced cross-border buyers. This guide is the complete picture in one read.

Whether you are a first-time buyer trying to understand your total acquisition cost, a seller calculating your net proceeds, or an investor modelling the after-tax yield on a buy-to-let property, the math below applies to you. I will walk through every Luxembourg property tax line by line, with worked examples (illustrations, not advice) for a typical €600,000 primary residence purchase, a €750,000 rental investment, and a €900,000 sale. By the end, you will have a working understanding of what you owe, when you owe it, and where the legitimate tax-efficiency opportunities lie. This is not tax advice for your specific situation — for that you should consult your notary or tax adviser — but it is the practical framework every Luxembourg property buyer and seller deserves to have before they sign anything.

Overview: The Five Property Taxes You Will Encounter

Luxembourg property ownership touches five main tax categories across the life cycle:

1. Registration tax and transcription tax — paid at acquisition (6% + 1% = 7% of the price, before any credit). In the City of Luxembourg, a communal surcharge equal to 50% of the registration duty (3% of the price) can apply; single-family houses and maisons de rapport are exempt (pfi.public.lu).
2. Bëllegen Akt tax credit — a reduction of registration tax for primary-residence buyers (up to €40,000 per person).
3. Annual property tax (impôt foncier) — paid yearly during ownership; the amount depends on the commune and the cadastral value (ask for the latest tax notice).
4. Capital gains tax (plus-value immobilière) — paid on resale if specific conditions apply.
5. Rental income tax — paid on net rental income if the property is let.

VAT (TVA) also features for VEFA off-plan new-build purchases, and inheritance/gift tax applies to transfers of property by gift or succession. Both are specialised topics worth understanding if they apply to you. The full guide on Hidden Costs of Buying Property in Luxembourg covers the broader cost picture beyond pure tax.

Registration Tax and Transcription Tax (At Acquisition)

Every Luxembourg property transfer triggers two acquisition-related taxes: droits d'enregistrement (registration tax) at 6 percent, and droits de transcription (transcription tax) at 1 percent. Both are calculated on the purchase price of the property and are paid by the buyer through the notary at the moment of the acte authentique. The combined headline rate is therefore 7 percent of the purchase price.

For a €600,000 acquisition, this means €42,000 of combined registration and transcription tax before any credit. For a €1,000,000 acquisition, €70,000. These are not optional, they are not reducible by negotiation, and they apply on every standard residential transaction in the country.

Some specific exceptions exist. Transfers between spouses or in certain inheritance and gift contexts are taxed differently. New-build VEFA purchases involve VAT mechanics that interact with the registration tax in ways that occasionally reduce the net burden. Commercial property transfers are subject to additional considerations. For standard residential purchases, however, 7 percent of price is the working baseline.

Bëllegen Akt Tax Credit (Reduction of Registration Tax)

The Crédit d'Impôt sur les Actes Notariés — commonly called the Bëllegen Akt credit — is the most important variable in Luxembourg property acquisition tax. As of 2026, the credit is up to €40,000 per buyer for acquisition of a primary residence. A couple buying jointly therefore claims up to €80,000. The €40,000 ceiling was made permanent by bill n°8540, approved by the Chamber of Deputies on 25 June 2025 (chd.lu, gouvernement.lu).

The credit applies against the registration and transcription duties calculated above. For example, with €40,000 per person: on a €600,000 main residence bought by a couple, the €80,000 credit covers the €42,000 of duties (the AED always collects a minimum of €100), and the unused balance remains available for a later purchase of a main residence. On a €1,000,000 purchase, the duties of €70,000 are covered; on €1,400,000, they fall from €98,000 to €18,000 (guichet.lu).

Key eligibility conditions:

• Primary residence only — not investment, not secondary residence.
• You must occupy the property as your main residence within 2 years of the deed (4 years for a building plot or a property under construction) and live there continuously for at least 2 years.
• If you rent it out, sell it or stop living in it before those 2 years, the full credit must be repaid with interest (exemptions exist, for example force majeure or divorce).
• It is not limited to first-time buyers: the credit can be used over several purchases until the amount per person is used up.

The credit is requested in the notarial deed itself: the notary records your request and your occupancy commitments. Confirm your eligibility with the notary before relying on the credit in your budget.

Annual Property Tax (Impôt Foncier)

Annual property tax is calculated from the property's valeur unitaire (a cadastral value that has not been updated for many years), multiplied by a rate set by each commune.

For most homes the annual bill is modest compared with the purchase price. To know the exact amount, ask the seller for the latest tax notice or ask the commune.

A reform of the property tax has been under discussion for some time. Check the current rules when you buy, and keep in mind that this is an area that may change.

Capital Gains Tax on Resale (Plus-Value Immobilière)

Luxembourg's capital gains regime on property resale is one of the most consequential and least understood pieces of the puzzle for sellers. The key distinctions:

• Primary residence exemption: If you sell your primary residence (where you have lived continuously), the capital gain is exempt from taxation. This is the most important exemption in the system and applies broadly to genuine primary-residence sales.
• Speculation profit: if you sell a property that is not your main residence less than 5 years after buying it (the speculation period), the gain is taxed at the ordinary progressive rates (marginal rate up to 42%). A temporary 2-year threshold applied only to sales between 1 January and 30 June 2025 (guichet.lu).
• Capital gain after that period: the gain is reduced by a decennial allowance of €50,000 (€100,000 for jointly taxed spouses or partners) and taxed at most at 21% (half the global rate). A temporary quarter rate (maximum 10.5%) applied only to gains realised between 1 July 2016 and 31 December 2018 and between 1 January 2024 and 30 June 2025; it has ended.
• Inflation adjustment: The acquisition cost basis is adjusted for inflation between purchase and sale, reducing the taxable gain in real terms.
• Eligible deductions: Genuine improvements to the property, acquisition costs, and resale costs can typically be added to the cost basis.

In practice: selling your main residence — exempt. Selling a rental property after the speculation period — the €50,000 (€100,000) allowance, then at most 21%. Selling within the speculation period — ordinary rates, which makes short-term resale much less attractive.

Rental Income Tax for Landlords

Rental income from Luxembourg property is taxable income, but a generous deduction regime keeps the effective burden moderate. The basic mechanic:

• Gross rental income is reduced by allowable expenses (mortgage interest — though not principal repayment — maintenance, syndic charges, insurance, depreciation, property tax).
• Net rental income (rent minus deductible costs) is added to your other income and taxed at the progressive income-tax rates; the rate that applies depends on your total income and personal situation (guichet.lu).
• Depreciation (amortissement) of the building — not the land — at the rates set by tax law; recent buildings can qualify for a higher rate under conditions. Check the current rates with your tax adviser.

The effective after-tax yield on a typical Luxembourg buy-to-let property depends heavily on the landlord's marginal tax rate and the property's specific deduction profile. Run the numbers for the specific property and your own tax situation. To compare purchase prices, which drive the yield, see the official prices per m² by commune.

Three Worked Examples

Example 1: First-time couple buying €600,000 primary residence

• Registration tax (6%): €36,000
• Transcription tax (1%): €6,000
• Total before credit: €42,000
• Bëllegen Akt credit (couple): covers the duties down to the €100 minimum
• Net acquisition duties: €100 (minimum)
• Capital gains tax if sold as primary residence: €0

Example 2: Investor buying €750,000 rental property (not primary residence)

• Registration tax (6%): €45,000
• Transcription tax (1%): €7,500
• Total acquisition tax: €52,500 (no Bëllegen Akt credit)
• Annual rental income (assumption for this example: 4.2% gross): €31,500
• Annual deductions: mortgage interest, charges and depreciation — they depend on your loan and the building
• Taxable rental income: gross rent minus these deductions
• Tax: added to your other income and taxed at the progressive rates (your rate depends on your situation)
• Capital gain if sold after 5 years: decennial allowance of €50,000 (€100,000 for a jointly taxed couple), then taxed at most at 21%

Example 3: Seller of €900,000 primary residence after 7 years (originally purchased for €700,000)

• Sale price: €900,000
• Capital gains tax (primary residence exemption applies): €0
• Total seller cost: agent commission (if used) + final notary fees + any compromis-related legal costs

Key Takeaways

• Acquisition duties are 7% of the price (6% registration + 1% transcription), but the Bëllegen Akt credit can cover most or all of them for buyers of a main residence.
• Annual property tax is generally modest; the exact amount depends on the commune.
• Main-residence sales are exempt. Other sales after the speculation period benefit from a €50,000 allowance (€100,000 for a couple) and a maximum rate of 21%.
• Rental income is taxable but deductions for interest, charges, and depreciation typically keep the effective burden moderate.
• Plan the tax picture over the whole ownership period, not only at purchase.

Frequently Asked Questions

What is the total tax cost of buying a €600,000 property in Luxembourg?

For a couple buying their main residence with their full Bëllegen Akt credit available: the duties are covered except the €100 minimum. Without the credit: 7% of the price (€42,000). On top of that: notary fees (set by an official scale — try the notary fees calculator), mortgage registration costs if you borrow, and the annual property tax.

How much does the Bëllegen Akt credit save me?

Up to €40,000 per buyer (€80,000 for a couple) against the registration and transcription duties. For example, for a couple with the full credit available, it covers the whole 7% on a price up to about €1,140,000 (€80,000 ÷ 7%).

Is Luxembourg's annual property tax really that low?

It is generally modest, because it is based on cadastral values that have not been updated for many years. The exact amount depends on the commune — ask for the seller's latest tax notice. A reform has been discussed, so check the current rules.

If I sell my Luxembourg home, will I owe capital gains tax?

For a genuine main-residence sale, no — it is exempt. For other properties sold within the speculation period, the gain is taxed at the ordinary progressive rates. After that period, the gain is reduced by a €50,000 decennial allowance (€100,000 for a jointly taxed couple) and taxed at most at 21%.

How is rental income taxed in Luxembourg?

Net rental income (gross rent minus mortgage interest, maintenance, charges, depreciation, etc.) is added to your other income and taxed at the progressive income-tax rates, depending on your total income and personal situation. Depreciation deductions are particularly important and can substantially reduce taxable rental income.

Do non-residents pay different property taxes?

Registration tax, transcription tax, and annual property tax are the same regardless of nationality or residency. Rental income tax for non-resident landlords applies on the Luxembourg-source income with somewhat different overall income-tax dynamics. Capital gains rules also apply to non-residents in essentially the same way as residents.

Should I consult a tax adviser before purchasing?

For a standard primary-residence purchase, the notary typically handles all tax mechanics correctly. For more complex situations — investor purchases, partial-share acquisitions, transfers between family members, properties intended for short-term resale — consulting a Luxembourg tax adviser before signing is genuinely valuable and inexpensive insurance.

Conclusion

The Luxembourg property tax system is predictable once you understand how its layers fit together. The Bëllegen Akt credit can cover most acquisition duties on a main residence. Annual property tax is generally modest. Main-residence sales are exempt from capital gains tax. Rental income is taxable, with deductions for interest, charges and depreciation. Where buyers get into trouble is when they treat the tax picture as an afterthought rather than part of their property plan. If you want a clear read on how taxes affect your buying, selling or investment situation in 2026, the conversation costs nothing — and for advice on your own case, speak to your notary or tax adviser.
