Notary Fees & Closing Costs in Luxembourg: The Real Numbers (2026)

Almost every buyer I meet in Luxembourg arrives with the same blind spot. They have worked out the purchase price to the last euro, they have a mortgage agreement in principle from their bank, and they are ready to sign — and then they discover that the property costs materially more than the number on the listing. The difference is closing costs: the registration duties, the notary's fees, the transcription tax and the mortgage-registration costs that every buyer pays on top of the price. In 2026, on an existing property, these typically add up to somewhere between 7% and 10% of the purchase price. On a €800,000 apartment, that is a five-figure sum that has to be paid in cash, on the day of signing, from money the bank generally will not lend against.

In my thirteen years on the Luxembourg market, I have watched more deals wobble over closing costs than over the price itself — because buyers budget for the price, forget the costs, and then find themselves €50,000 short three weeks before the acte de vente. This guide is the conversation I have with every buyer before they fall in love with a property. I will walk you through exactly what you pay on top of the price, where each euro goes, how the Bëllegen Akt tax credit changes the maths for owner-occupiers, why a new-build follows completely different rules, and — most usefully — a fully worked example with real 2026 figures so you can see the whole picture in one place. None of this is meant to frighten you off buying. It is meant to make sure that when you sign, there are no surprises left.

What a Buyer Actually Pays on Top of the Price

Let me start with the honest headline, because it is the number that matters most for your planning. When you buy an existing property in Luxembourg — a resale apartment or house, as opposed to a new build sold off-plan — you pay the agreed purchase price to the seller, and then you pay a separate bundle of costs to complete the transaction legally. That bundle has three main parts: the transfer taxes that go to the State (registration duties and the transcription tax), the notary's own professional fees, and a set of smaller disbursements and administrative costs. On top of all that, if you are financing with a mortgage, there is a further cost to register the loan against the property.

For an existing property bought without the Bëllegen Akt tax credit, the transfer taxes alone come to 7% of the price. Add notary fees, disbursements and mortgage registration, and the all-in figure typically lands between 8% and 10%. The tax credit, which I will explain in detail below, can pull that figure down substantially for owner-occupiers — sometimes to the region of 3% to 5% on a modestly-priced first home. For a new build, the rules change entirely: you pay VAT rather than the full registration duties, and the structure is different again. The single most important thing to understand is that these costs are real, they are paid in cash at signing, and your bank will generally not lend against them.

Registration Duties and the Transcription Tax: The 7%

The largest single element of Luxembourg closing costs is the pair of transfer taxes levied by the State on the sale of an existing property. There are two of them, and it is worth understanding them separately because the Bëllegen Akt credit applies to one but not the other.

The first is the registration duty (droit d'enregistrement), charged at 6% of the purchase price. The second is the transcription tax (droit de transcription), charged at 1% of the purchase price, which pays for the transfer to be recorded at the mortgage registry (Administration de l'Enregistrement, des Domaines et de la TVA). Together these make up the 7% headline figure that every Luxembourg buyer has heard about. There is an important local nuance: for properties located in Luxembourg City, a municipal surcharge (surtaxe communale) of an additional 3% applies to the registration duty portion for certain transactions — historically this has affected buy-to-let and non-owner-occupied purchases in the capital, so a pure investment purchase in the City can carry a heavier transfer-tax load than an owner-occupied one. The exact application depends on the property and the buyer's intended use, and it is precisely the kind of detail your notary confirms in advance.

On a €700,000 existing apartment, then, the base transfer taxes are €42,000 in registration duty plus €7,000 in transcription tax — €49,000 before any credit is applied. That is why the Bëllegen Akt matters so much, and why it deserves a section of its own.

The Notary's Fees: Regulated, Degressive, and Smaller Than You Think

Here is where buyers are often pleasantly surprised. The notary's own professional fee — the honoraires — is regulated by a State-set scale, not negotiated, and it is far smaller than the transfer taxes. The scale is degressive: it is charged as a percentage of the price that decreases as the price rises, so the marginal rate on the top slice of an expensive property is well below 1%. In practice, on a typical Luxembourg residential purchase, the notary's fee lands in the region of 0.5% to 1% of the price, and the effective rate falls as the price climbs.

Because the scale is set by law, the fee is essentially the same whichever notary you choose — you cannot shop around for a cheaper rate, which also means you cannot be overcharged. Two points buyers frequently miss: first, the notary's fee attracts VAT at 17%, which is added to the honoraires; second, the notary is not simply a fee-earner but a public officer who guarantees the legal security of the transaction, verifies title, checks for existing charges and mortgages on the property, and ensures the taxes are correctly calculated and paid. In Luxembourg you do not need a separate lawyer for a standard purchase — the notary performs that protective function for both sides, and the buyer chooses (and pays) the notary.

Disbursements and Administrative Costs

Beyond the taxes and the notary's fee, there is a cluster of smaller costs the notary collects on your behalf and passes on. These are the débours and administrative charges: land registry searches, the cost of obtaining certificates and extracts, mortgage-registry checks to confirm the property is sold free of encumbrances, cadastral documents, and various stamp and filing fees. Individually they are modest; collectively they typically add somewhere in the region of a few hundred to a couple of thousand euros to the bill, depending on the complexity of the transaction and the property.

They are not a source of nasty surprises — a competent notary will give you a detailed décompte (statement of account) well before signing, itemising every euro — but they are real, and they belong in your budget. What I always tell buyers is to ask the notary's office for a written cost estimate as soon as the compromis (preliminary sale agreement) is signed. You are entitled to it, it takes them minutes to produce, and it removes all the guesswork.

The Bëllegen Akt Tax Credit: How Owner-Occupiers Save

This is the single most valuable relief available to Luxembourg buyers, and understanding it properly can change your budget by tens of thousands of euros. The Bëllegen Akt — literally "cheap deed" in Luxembourgish — is a tax credit on the registration and transcription duties, granted to individuals who buy a property to live in it as their main residence. It is not a discount on the price; it is a credit that offsets the transfer taxes you would otherwise owe.

The credit is granted per buyer. Each qualifying individual receives an allowance that offsets a fixed amount of transfer duties — in recent years this has stood in the region of €40,000 per person, meaning a couple buying together can pool their credits for a combined offset in the region of €80,000. Because the credit is applied against the duties rather than the price, a couple buying a first home can see a very large part — sometimes all — of their 7% transfer-tax bill wiped out, provided the duties do not exceed the pooled credit. The essential conditions are that the property must become your principal residence, that you occupy it within a defined period, and that you hold it as your main home for a minimum period afterwards; if you sell or stop occupying it too soon, part of the credit can be clawed back.

Two things are worth stressing. First, the credit applies only to the registration and transcription duties — it does not reduce the notary's fee, the VAT on that fee, or the disbursements, all of which you still pay in full. Second, the rules and the exact credit amount are set by law and have been adjusted several times in recent years, including temporary reinforcements introduced to support the market during the 2023–2024 slowdown. Because the precise figure and conditions can move, I always confirm the current amount with the notary for each specific purchase rather than relying on last year's number. The notary fees calculator is a useful first estimate, but the notary's written décompte is the figure you budget against.

The Cost of Registering Your Mortgage

Here is the closing cost buyers forget most reliably. If you finance your purchase with a mortgage — as the overwhelming majority of buyers do — the loan itself has to be secured against the property by a mortgage deed (acte de prêt or inscription hypothécaire), and registering that security carries its own duties and fees, entirely separate from the purchase deed. There is a registration duty and transcription tax on the mortgage inscription, plus a notary's fee for drawing up the loan deed, plus the associated disbursements.

As a rough planning figure, the total cost of registering a mortgage typically comes to somewhere in the region of 1% of the loan amount, though the effective rate varies with the size of the loan and the structure of the security. On a €600,000 loan, that can mean several thousand euros on top of everything else — and it is a cost the Bëllegen Akt credit does not touch. Some buyers reduce it slightly by registering the mortgage for a lower nominal amount than the loan, or by using alternative security structures, but these are decisions to take with your notary and your bank, weighing the saving against the flexibility you give up. The key point for budgeting is simply this: do not forget it exists.

New Builds (VEFA): A Completely Different Tax Structure

If you are buying a new-build property off-plan — a vente en l'état futur d'achèvement, or VEFA — the tax rules are not simply a variation on the resale rules; they are a different system. On a new build, the construction portion of the price is subject to VAT rather than to the full registration duties, while the land portion is treated separately. Luxembourg applies a super-reduced VAT rate of 3% on the construction of a main residence, in place of the standard 17% rate, subject to conditions and to a cap on the total tax advantage per dwelling. This 3% regime is one of the most significant reliefs in the Luxembourg system, and it is specifically designed to make owner-occupied new construction more affordable.

The practical consequence is that the closing-cost profile of a new build looks quite different from that of a resale. You do not pay the full 6% registration duty on the built portion; instead you pay the favourable VAT rate on construction, registration duty on the land share, and the usual notary and mortgage costs. Whether a new build or a resale works out cheaper on closing costs depends heavily on the land-to-construction split, the price, and your eligibility for the reliefs — which is exactly why a like-for-like comparison, run by the notary for the two specific properties you are weighing, is worth far more than any rule of thumb. If you are choosing between an off-plan apartment and an equivalent resale, ask for the closing-cost breakdown on both before you decide.

A Worked Example: €850,000 Apartment in 2026

Numbers on their own are abstract, so let me put them together in a single realistic case. Imagine a couple buying an existing two-bedroom apartment in a good Luxembourg City neighbourhood for €850,000 as their main residence, financing €680,000 with a mortgage and covering the rest — and all the closing costs — from savings. Here is how the closing costs break down. All figures are illustrative 2026 estimates and rounded; your notary's décompte is the binding version.

The two columns tell the whole story. Without the tax credit — for example, if this were a buy-to-let purchase rather than a main residence — the closing costs approach €76,000, roughly 9% of the price. With the Bëllegen Akt credit pooled across both buyers absorbing the transfer duties, the same purchase costs the couple in the region of €16,500 to close, closer to 2% of the price. That swing of nearly €60,000 is the difference between owner-occupier and investor tax treatment on this property — and it is why establishing eligibility for the credit early is one of the most financially consequential steps a Luxembourg buyer takes.

When Each Payment Falls Due

Timing matters as much as amount, because closing costs are not spread out — they are concentrated. When you sign the compromis de vente (the preliminary agreement), you typically pay a deposit, usually in the region of 10% of the price, into an escrow or the notary's account. Then, on the day you sign the acte de vente (the final authentic deed) before the notary — usually a few weeks to a couple of months after the compromis — the balance of the price and the entire bundle of closing costs must be settled. The notary will not proceed to sign until the full amount, price plus costs, is confirmed as available.

This concentration is exactly why buyers get caught out. Your mortgage funds the price (up to the bank's loan-to-value limit), but the closing costs almost always have to come from your own cash. A buyer with a €680,000 mortgage approved on an €850,000 flat still needs, on top of their €170,000 price contribution, the closing costs in cash on signing day. Knowing that number precisely — from the notary's written décompte, not a rough estimate — weeks in advance is what separates a calm signing from a scramble.

Key Takeaways

• On an existing Luxembourg property, closing costs typically run 8% to 10% of the price before any tax credit — driven mainly by the 7% transfer taxes (6% registration + 1% transcription).
• The notary's own fee is regulated, degressive, and modest — in the region of 0.5% to 1% plus 17% VAT — and is the same whichever notary you choose.
• The Bëllegen Akt tax credit, granted per buyer to owner-occupiers, can offset a very large part of the transfer duties — a couple can pool a combined credit in the region of €80,000.
• Registering your mortgage is a separate cost, roughly 1% of the loan, that the tax credit does not touch — and that buyers most often forget.
• New builds (VEFA) follow different rules entirely, including the 3% super-reduced VAT on the construction of a main residence.
• Closing costs are paid in cash at signing and are generally not covered by your mortgage — get the notary's written estimate as soon as the compromis is signed.

Frequently Asked Questions

How much are notary fees in Luxembourg in 2026?

The notary's own professional fee is set by a regulated, degressive scale and typically lands in the region of 0.5% to 1% of the purchase price, plus 17% VAT. It is small relative to the transfer taxes. When people say "notary fees" loosely, they usually mean the entire closing-cost bundle — taxes, fee and disbursements — which on an existing property runs closer to 8% to 10% before any tax credit.

What is the 7% everyone talks about?

The 7% is the transfer tax on the sale of an existing property: 6% registration duty plus 1% transcription tax, both calculated on the purchase price and paid to the State. It is the single largest closing cost, and it is the part that the Bëllegen Akt tax credit can offset for owner-occupiers.

How much can the Bëllegen Akt tax credit save me?

The credit is granted per buyer and offsets the registration and transcription duties up to a fixed amount — in recent years in the region of €40,000 per person, so a couple can pool a combined offset in the region of €80,000. For a first home priced so that the 7% duties fall within the pooled credit, this can wipe out most or all of the transfer-tax bill. The exact amount is set by law and has changed in recent years, so confirm the current figure with your notary.

Does the tax credit reduce the notary's fee too?

No. The Bëllegen Akt applies only to the registration and transcription duties. The notary's professional fee, the VAT on that fee, the disbursements and the mortgage-registration costs are all payable in full regardless of the credit.

Are closing costs different for a buy-to-let purchase?

Yes, significantly. The Bëllegen Akt credit is for main residences, so an investment purchase does not benefit from it and pays the full 7% transfer taxes. Purchases in Luxembourg City can also carry a municipal surcharge on the registration duty for non-owner-occupied transactions. The gap between owner-occupier and investor closing costs on the same property can run to tens of thousands of euros.

Can I add the closing costs to my mortgage?

Generally not in full. Luxembourg banks lend against the property's value, and closing costs are not part of that value, so most buyers must fund them from their own cash at signing. Some buyers negotiate a slightly higher loan to help, but you should plan on paying the costs yourself and treat any bank flexibility as a bonus, not an assumption.

Why is buying a new-build taxed differently?

A new build sold off-plan (VEFA) is taxed partly through VAT on the construction rather than through the full registration duty. Luxembourg applies a super-reduced 3% VAT rate on the construction of a main residence, subject to conditions and a cap. The result is a different — and often favourable — closing-cost profile, but whether it beats a resale depends on the specific land-to-construction split and price.

When exactly do I pay the closing costs?

You pay a deposit (typically around 10%) at the compromis stage, and the balance of the price plus the entire closing-cost bundle on the day you sign the final acte de vente before the notary. The notary requires the full amount to be available before signing, so you need the cash ready weeks in advance.

Conclusion

Closing costs are the part of a Luxembourg purchase that rewards preparation and punishes surprise. The mechanics are not complicated once they are laid out: 7% in transfer taxes on an existing property, a modest regulated notary fee with VAT, a handful of disbursements, and a separate cost to register your mortgage — reduced, sometimes dramatically, by the Bëllegen Akt credit if you are buying a home to live in. What catches buyers out is never the concept; it is discovering the number too late, in cash, weeks before signing. Do the arithmetic at the first viewing, ask the notary for a written estimate the moment the compromis is signed, and confirm your eligibility for the tax credit early. Get those three things right and the closing table holds no surprises — only keys.
