At some point between the reservation and the notary appointment, every foreign buyer needs one number verified: what does the state take on this purchase? The forums supply three contradictory answers — "it's 3%", "it's up to 6% now", "you pay 21% VAT" — and all three are fragments of a system that is actually quite orderly once you see its single organising rule.
The rule is this: every acquisition falls under exactly one of two regimes, never both. Which regime depends on what you are buying — and most of the confusion online comes from people comparing numbers across the boundary without noticing it exists. This page walks the boundary, the current figures on each side, the filing mechanics, and the one trap that converts a seller's convenience into the buyer's problem. State taxes only; nothing here is anyone's fee.
The boundary: resale or first supply
Montenegro's Law on Real Estate Transfer Tax (Official Gazette of Montenegro 36/13, with the amending law in 28/23) defines the taxable event broadly: any acquisition of ownership of immovable property — sale, exchange, inheritance, gift, acquisition through liquidation or court decision (Article 4). But Article 6 carves out the decisive exception: the acquisition of newly constructed buildings on which VAT is paid is not a transfer for the purposes of this tax.
So the boundary runs between the second-hand market and the first supply of a new build:
- Resale (second-hand) property → real estate transfer tax, paid by the buyer, on the progressive scale below. No VAT.
- New build, first supply by a VAT-registered developer → 21% VAT, included in the purchase price under the VAT rules, with the standard rate confirmed unchanged into 2026. No transfer tax.
One purchase, one regime. Anyone quoting you both taxes on the same acquisition is describing a transaction that does not exist — and anyone comparing a resale's "3–6%" against a new build's "21%" is comparing a tax you pay on top of the price against a tax already sitting inside it. The like-for-like comparison is done on total acquisition cost, which is an arithmetic exercise, not a tax mystery.
The transfer tax: progressive since 1 January 2024
For decades the answer really was a flat 3%, which is why half the internet still says so. The amending law published in Official Gazette 28/23 replaced it, for tax liabilities arising from 1 January 2024, with a progressive scale:
| Tax base (market value) | Transfer tax |
|---|---|
| Up to €150,000 | 3% |
| €150,000.01 to €500,000 | €4,500 + 5% of the amount above €150,000.01 |
| Above €500,000.01 | €22,000 + 6% of the amount above €500,000.01 |
Two worked examples make the marginal structure concrete. A €300,000 apartment: €4,500 for the first band, plus 5% of the €150,000 above it — €7,500 — for a total of €12,000, an effective 4%. A €700,000 house: €22,000 for the first two bands, plus 6% of the €200,000 above the half-million line — €12,000 — for a total of €34,000, an effective 4.86%. The old flat 3% would have said €9,000 and €21,000; budgeting from a stale forum post leaves a five-figure hole at exactly the moment the money is committed.
Two structural cases follow the same logic. In an exchange of properties, each participant is a taxpayer for what they acquire, with the base determined separately for each side at the market value of the property received. Where several buyers acquire co-ownership shares, each is taxed proportionately on the market value of their own share — relevant for the couples and sibling groups who make up a large share of foreign purchases, because each files their own return rather than one return for the deal.
The taxpayer is the buyer (Article 7). In an exchange, each participant is taxed on what they acquire; in inheritance and gift, the heir or donee is the taxpayer — though Article 14 exempts the first order of succession, spouses and parents, which is why most family inheritances produce no charge. That breadth surprises people: the "transfer tax" is really an acquisition tax, and it reaches transactions with no purchase price at all.
When the clock starts
The 15-day machinery below only makes sense once you know when the liability is born, and Article 15 sets a different starting gun for different acquisitions. For an ordinary purchase, the obligation arises on the day the contract is concluded. For a future property — the off-plan case — it arises only on handover or taking possession, which is why off-plan buyers pay their transfer tax (where the transaction is in that regime at all) at delivery rather than at signing. Acquisition by court or administrative decision starts the clock at the decision's finality, and a lifetime-maintenance contract at the death of the person maintained.
The authority, meanwhile, does not depend on your honesty to learn about the deal: notaries, courts and the cadastre are obliged to forward the acts they process to the tax authorities on a statutory schedule, and where a contract is never delivered or is delivered late, the liability is simply deemed to arise on the day the authority finds out. The reporting web is closed by design — the only question is whether your filing beats it.
Filing: fifteen days, self-assessed, paid on the spot
The mechanics are compressed and unforgiving. Under Article 16, the taxpayer must file a return with the tax authority within 15 days of the tax liability arising, computing the tax themselves; the contract or other acquisition document goes in with the return; and the tax is paid simultaneously with the filing. There is no assessment-then-invoice rhythm of the kind Western European buyers expect — the deadline, the computation and the payment arrive together.
Miss the window and the process does not politely wait: if the taxpayer fails to file, the authority files for them and determines the tax, and the omission sits in penalty territory. In practice the notarised contract's journey to the registry and the tax filing run as one coordinated sequence — which is one more reason the completion logistics described in our purchase process guide are sequenced the way they are.
The under-declared price trap
Here is the trap that matters more than the rates. The tax base is the market value of the property at acquisition (Article 9); where there is a price, the base is the total consideration — money, assumed debts, other property, anything given for the transfer. But Article 10 gives the tax authority a weapon buyers forget: where the contract price is below market value, or no price is stated, the authority determines the market value itself, through an authorised officer using comparative data on sales of similar property in the same area and period.
Now connect that to a suggestion foreign buyers hear disturbingly often: "we write a lower price in the contract — it saves tax." Observe who carries each consequence. The reassessment is a tax determination against the buyer, arriving with the difference and the associated exposure. The understated contract price becomes the buyer's documented acquisition cost, quietly inflating the taxable gain on any future resale. And the buyer has signed an official document understating a transaction in which the money actually moved — a fact that never improves with age. The seller, meanwhile, pockets the benefit the arrangement was designed for. It is a trade in which one party takes the savings and the other takes the risk, and the buyer is not the first party.
The defensible position is unexciting: the contract states the real price, the valuation question is left to the authority's comparative data if it ever arises, and the buyer's numbers survive every later audit — including the one that happens at resale. How the price is evidenced from the first document onwards starts earlier than buyers think, at the reservation and pre-contract stage.
The new-build path: what "VAT included" must actually mean
On the other side of the boundary, the first supply of a newly constructed unit by a VAT-registered developer carries 21% VAT, and the acquisition is outside the transfer tax entirely by Article 6. Three checks keep this path clean.
First, confirm the seller genuinely is supplying within the VAT system — the exclusion works because VAT is paid, not because the building is new. Second, confirm what the quoted price contains: "VAT included" should be visible in the contract's price clause, not assumed from the brochure. Third, remember the boundary cuts by transaction, not by building: the developer's first sale to you is the VAT supply, but when you resell that same apartment in five years, your buyer is in the transfer-tax regime — the building's youth does not travel with the title.
And this is where the like-for-like comparison belongs. Take €400,000 as the money a buyer is willing to commit. A resale listed at €400,000 costs €400,000 plus transfer tax of €17,000 — €4,500 for the first band and 5% of the €250,000 above it — a total of €417,000. A new build marketed at "€400,000, VAT included" costs €400,000, full stop: the 21% VAT is already inside the figure, borne economically through the developer's price rather than added at the registry. Neither regime is generically "cheaper"; the arithmetic depends entirely on how each side quotes, which is why the only comparison that means anything is total funds out the door against total rights received.
For completeness: this page covers what you pay to acquire. Holding the property triggers the annual municipal real-estate tax, set within the statutory 0.25%–1.00% band of market value, and renting it out or selling it has its own income-tax consequences — the wider picture sits in our Montenegro tax and accounting guide, and cross-border coordination with your home system is where our international tax service works.
Send us the draft contract or the reservation documents before you sign or transfer anything, and tell us whether the property is a resale or a first supply. We will confirm which regime the transaction is in, compute the actual figure on the actual base, and flag anything in the price clause that would put your filing at odds with the money that really moved.
