VAT and Tax on Real Estate Transactions: The Full Guide

Most property deals do not turn expensive because of the price. They turn expensive because of a bill no one budgeted for — usually VAT or tax that surfaces after the contract has been signed. A site that turned out to be a VAT-liable building site. A newly built property that brought with it an adjustment liability the buyer assumed without realising it. A gain taxed harder than expected, because the property was never covered by any exemption.

What these cases share is that the consequences are knowable in advance. VAT and tax on real estate follow fixed patterns that can be mapped out before the deal is structured. The point is not that the rules are impenetrable — it is that they determine how a deal should be put together, and that this clarification belongs before signing, not in an aftermath. This guide pulls together the parts a professional party should have a firm grip on: when there is VAT, when there is not, what the adjustment liability means, how the gain is taxed, and which duties come with the transfer.

The main rule: real estate is VAT-exempt — with important exceptions

The starting point in Danish VAT law is simple: the sale of real estate is exempt from VAT. But precisely because that is the starting point, it is the exceptions that cost money. Two categories are VAT-liable when sold by a taxable person (someone carrying on economic activity with the property):

• Building sites. A site that, given its zoning status and planning, can be built on is typically sold with VAT when the seller is a taxable person.
• New buildings. A newly constructed building — and a building that has been substantially converted — is regarded as “new” for a period after completion, and a sale within that period is VAT-liable.

The decisive distinction therefore does not run between “business” and “private” in the everyday sense, but between a taxable person and an ordinary private disposal. A private individual selling their own home, or a site that is not part of an economic activity, normally does not trigger VAT. A developer, a company or a landlord selling as part of its business does.

Rule of thumb: settle early whether the seller is a taxable person, and whether the asset is a building site or a new building. If the answer is yes on both counts, expect VAT — and have it reflected in how the price is worded in the contract.

Because the boundaries here are detailed and practice keeps developing, the specific classification should always be verified with an adviser or against the Danish Tax Agency’s current guidance before it is relied upon.

VAT on building sites

The question of when a site is a building site in VAT terms is one of the most frequent points of dispute in practice. What matters is whether, under the physical planning, the site is designated for purposes that make development possible — not whether anything stands on it today. An undeveloped plot in an area covered by a local plan for housing is a building site. Agricultural land with no development option, as a starting point, is not.

This has practical consequences that go beyond the VAT amount itself:

• The price agreement. It must be clear whether the agreed price is inclusive or exclusive of VAT. Ambiguity here is a classic source of conflict — and of an unexpected bill for whoever carries the risk.
• The right of deduction. A VAT-liable buyer who will use the site for VAT-liable purposes can typically deduct the input VAT. In that case the VAT is a liquidity question, not a final cost. For a buyer without a right of deduction, it is by contrast a genuine added expense.
• Demolition and “new” status. If a site is sold with a building that has been agreed to be demolished, the transaction may, depending on the circumstances, be treated as the sale of a building site. The legal classification follows the substance of the transaction, not just its heading.

This is an area where the planning conditions underlying the assessment can be looked up in the public registers. The use provisions of the local plan in Plandata.dk (the national planning register) and the status of the site form the factual foundation — the VAT conclusion is built on top. If you want to dig a spade deeper into when the sale of a site specifically becomes VAT-liable, see the dedicated walkthrough of when the sale of a building site triggers VAT liability. If you already understand how a local plan’s provisions are read and interpreted, you already have half the basis for assessing the building-site question.

New buildings and the five-year rule

The other large VAT-liable category is the sale of new buildings. A building is regarded as new for a defined period after it is taken into use — and a sale within that period is VAT-liable when the seller is a taxable person. The same applies to buildings that have been converted so substantially that they are treated, for VAT purposes, on a par with new construction.

The practical consequence is that the timing of the sale takes on a significance of its own. A sale shortly after completion plays out differently from a sale further down the line. For developers and investors who build or thoroughly convert with a view to resale, this is a planning factor that should feed into the exit strategy from the outset — not something discovered once the sale is already under way.

The rules on what makes a building “new”, when the date of first use is counted from, and when a conversion crosses the materiality threshold, carry a fair amount of nuance. The full mechanics are described in the article on new buildings and the five-year rule for VAT. The specific time limits and thresholds should always be checked against the VAT legislation in force, since this area in particular is regularly refined in practice.

The adjustment liability — the hidden item in the transfer

If one topic deserves particular attention in a transaction involving commercial or rental property, it is the VAT adjustment liability. This is an obligation that attaches to real estate where VAT has been deducted for construction or conversion — because the right of deduction is conditional on continued VAT-liable use over a span of years. If the use changes, or the property is transferred, part of the original deduction may have to be adjusted.

What makes the liability dangerous is that it is easy to overlook: it is not necessarily apparent from the price, it is tied to the property’s deduction history, and on a transfer it can pass to the buyer. A buyer who assumes the liability without having priced it can end up facing a future adjustment that was never factored into the deal.

In practice this means that, in a due diligence process, you must:

• Map the deduction history — has VAT been deducted for construction or substantial conversion, and when?
• Establish any adjustment liability — its size, remaining term, and whether it is intended to be assumed by the buyer.
• Address it in the contract — who bears the liability, and is it reflected in the price and in the completion balance?

Voluntary VAT registration for commercial letting is closely bound up with this, because the registration is precisely what grants the right of deduction and thereby triggers the liability. The whole interplay between voluntary registration, deduction and liability is unpacked in the walkthrough of the VAT adjustment liability when letting commercial property — required reading for anyone buying or selling let commercial space.

Tax on a property sale: capital gains

Where VAT concerns the transaction, tax concerns the profit. When a property is sold at a gain, the starting point is that the gain is taxed — but how, and whether any exemption applies, depends on the nature of the property and the owner’s circumstances.

Two basic cases are worth keeping apart:

• Owner-occupied home. The gain on the sale of a home the owner has personally occupied is, under the ordinary conditions, exempt from tax. This is one of the best-known exceptions — but it applies precisely to one’s own occupation, not to investment and rental properties.
• Rental and investment properties. Here the gain is, as a starting point, taxable under the rules on property gains. The gain is calculated, broadly speaking, as the difference between the adjusted acquisition cost and the disposal price, with a series of add-backs and adjustments, and is taxed in the owner’s hands.

For companies, the property gain forms part of the company’s taxable income on a par with other earnings, while for individuals it is calculated under the capital-gains rules and taxed as part of income. This means that the ownership structure — whether the property is held privately or in a company — in itself affects taxation and should therefore be settled before investing.

Calculating a property gain on the sale of a rental property involves more components than most expect — acquisition cost, improvement expenditure, add-backs and prior depreciation all come into play. The practical approach is set out in the article on capital gains tax on the sale of a rental property. The specific rates and calculation rules should always be verified against the tax legislation in force, or with a tax adviser, since this area in particular is regulated on an ongoing basis.

Land registration fee and the other costs of the transfer

Beyond VAT and capital gains tax, duties come with the transfer and settlement themselves. The land registration fee is paid on the registration of title (the deed) and on the registration of a mortgage, and it typically consists of a fixed part and a variable part calculated on the purchase price and the mortgage amount respectively. It is rarely a surprise in its own right, but it belongs in the overall calculation — especially in deals with high leverage, where the mortgage fee can be a noticeable item.

In practice it is worth remembering that:

• the fee is calculated on a basis that is not always equal to the nominal price — in certain cases a public valuation is used as a minimum basis,
• there are ways to transfer fee paid on an existing mortgage to a new one (a fee mortgage deed), which can reduce the cost of refinancing,
• the specific rates and calculation bases should be looked up in the land registration fee legislation in force, as they are adjusted from time to time.

The registration stage is at the same time where the factual picture of the property is confirmed: title, encumbrances and easements appear in tingbogen (the Land Registry), while building and area data are found in BBR (the Buildings & Dwellings Register) and matriklen (the cadastre). A thorough check of these registers is a precondition for even classifying the VAT and tax treatment — and is a fixed part of a proper due diligence on a site or property. In that connection, watch out for the classic pitfalls in BBR data, because errors in areas and use codes can propagate straight into the tax assessment.

How it all ties together before signing

The five questions a professional party should have answered before a deal is structured are manageable:

1. Is the seller a taxable person — and is the asset a building site or a new building? (VAT liability)
2. Is the price agreed inclusive or exclusive of VAT, and who has the right of deduction? (VAT handling)
3. Is there an adjustment liability, and who assumes it? (the hidden item)
4. How is the gain taxed given the property type and ownership structure? (tax)
5. Which duties come with the transfer and settlement? (land registration)

Together, the answers determine how the deal should be put together — and they all rest on the same factual foundation: the property’s status, planning conditions, title, encumbrances and areas in the public registers.

From register lookup to decision

The manual exercise of assembling this picture is real: planning conditions from Plandata.dk, title and easements from tingbogen, building and area data from BBR, ownership structure from CVR (the Central Business Register) — across sources, for each individual property. That is exactly the gathering that the Ejendomme (Properties) module in Arcili pulls together in one place: every property searchable, with detail tabs for BBR, planning conditions, land registration and economics among others, so the factual basis for the VAT and tax assessment lies in front of you before you even open the spreadsheet. Arcili does not make the tax decision for you — but it removes the hours of register lookups, so you can spend them on the assessment instead.
