Every buying guide on this site walks toward the same moment — you own the property. This page is about the opposite journey, and it exists for a reason buyers rarely appreciate at the start: the tax you will pay when you sell is largely decided by the paperwork you keep from the day you buy. The exit is planned at the entrance, or it is improvised years later at a price.
This is the sell-side twin of our transfer tax and VAT guide: that page covers what the state takes when you acquire; this one covers what it takes when you leave.
The regime in three sentences
Under the Personal Income Tax Law, a capital gain arises on the sale of immovable property — land, buildings, residential and business units — and the taxable amount is the difference between the sale price and the acquisition price (Articles 37a and 37b). The tax is computed annually at 15% and paid together with the annual tax return (Article 50a), which is due by the end of April for the previous year (Article 43). The rule reaches foreign owners directly: a non-resident is taxed on income realised in Montenegro and files a return for Montenegrin income on which no withholding was applied (Article 43) — and a property gain is exactly that.
Three structural points before the details. There is no separate "foreigner rate" — 15% applies to resident and non-resident individuals alike. The computation is annual, not per-transaction, which is why losses on one disposal can offset gains on another in the same period (Article 37h). And there is no holding-period exemption: owning the property for ten or twenty years does not, by itself, reduce or eliminate the charge — a point on which Montenegrin law disappoints buyers arriving with German or Austrian instincts.
The basis file: why day one decides year ten
The arithmetic is simple; the evidence is everything. Both ends of the subtraction are defined in ways that reward the owner who kept papers.
The sale price is the contracted price, reduced by documented reconstruction costs and the costs of the sale (Article 37c). The renovation you paid for in cash with no invoices does not exist for this computation; the same works, documented, are a euro-for-euro reduction of the taxable gain. Where the contracted price is below market, the tax authority determines the sale price itself — the same market-value discipline we described on the buy side.
The acquisition price is the price at which you acquired the property — or the value the tax authority determined at your acquisition under the transfer-tax rules (Article 37d). Read that twice, because it closes a familiar loop: the under-declared purchase price we warned about in the buy-side guide returns at exit as a low basis and a correspondingly inflated gain. The law also answers the harder cases: a self-built property's basis is its documented construction cost; property received by gift or inheritance carries the donor's or deceased's own acquisition price — a carry-over basis that can hide a decades-old, near-zero figure inside a recent inheritance; and the basis is indexed annually for retail-price growth from acquisition to sale, an inflation adjustment owners routinely forget to claim. Where the acquisition price genuinely cannot be established, the law deems it to be 80% of the sale price — a backstop, not an election, and rarely better than a real, documented basis.
The practical instruction writes itself: from completion day, keep the notarised contract, the transfer-tax assessment, every renovation invoice, and later the sale-side costs — one file, kept as if the tax office will read it, because one day it will.
A worked example makes the file's value concrete. An owner bought at €250,000, spent €30,000 on a documented reconstruction, and sells at €400,000 with €8,000 of documented sale costs. The computation runs: sale price €400,000 minus €38,000 of documented costs is €362,000; minus the €250,000 acquisition price — before the indexation adjustment reduces it further — the gain is €112,000 and the tax €16,800. The same owner with the same history but no invoices computes €400,000 minus €250,000: a €150,000 gain and €22,500 of tax. The €5,700 difference is not tax planning; it is a folder. And the owner who also under-declared the purchase at €180,000 seven years ago now starts the subtraction €70,000 lower still — the buy-side shortcut, priced at exit.
The exemptions that exist — and the one that does not
Article 37g exempts three situations, and their shape matters. The gain is not taxed where the property served the taxpayer as their sole and main place of residence; where the transfer is between spouses or life partners and directly connected with marriage, its dissolution, or inheritance of property; and where the property is gifted to relatives of the first order of succession.
Notice what is on the list and what is not. The residence exemption turns on the property genuinely being your principal home — a holiday apartment used six weeks a year does not become one by assertion. The family exemptions align with the transfer-tax exemptions on the buy side and with the succession rules we set out in the inheritance guide — though heirs should remember the carry-over basis: an exempt transfer today is not an exempt sale tomorrow. And no exemption rewards mere patience: the absence of a holding-period rule means the investor's exit is taxable in year two and in year twenty alike.
Selling from abroad: the mechanics
The non-resident owner's obligations are compact but real. The gain is computed annually and the tax paid with the return, due by end of April of the following year; the non-resident files because no one withholds for them. Filing from abroad runs through the ordinary Montenegrin return process — in practice with local representation handling the submission, the supporting file, and any dialogue with the authority about basis or valuation.
One illusion to retire: the idea that a sale by a foreign owner, paid abroad, might simply not come to the authority's attention. The reporting web we described on the payment side runs in both directions — notaries, courts and the cadastre are statutorily obliged to deliver the instruments of every ownership change to the tax authorities on a fixed schedule. The authority learns of your sale by design, with the contract price attached. The only question a missing return leaves open is when the conversation starts and on whose terms.
The treaty layer: what "double taxation" actually means here
Selling as a foreign resident raises the two-country question, and the answer follows the standard international pattern: under the OECD-model rule reproduced in Montenegro's treaties, gains from immovable property may be taxed in the state where the property is situated — Montenegro — and the owner's home state then relieves the double burden by its treaty method. We have verified this concretely in the treaties our readers actually use: the Ireland–Montenegro convention and the UK–Yugoslavia convention that applies to Montenegro both allocate immovable-property gains to the situs state and provide credit relief at home.
The practical consequence: the Montenegrin 15% is usually not an additional cost but a creditable one — the real question is the home-country computation, its rate above 15%, its own reliefs and its own filing. That analysis belongs with your home advisers, as our nationality guides keep repeating, and the coordination between the two filings is where our international tax practice works.
The company-held exit is a different door
Owners who bought through a Montenegrin company face a different geometry at exit, decided years earlier by the acquisition structure. If the company sells the property, the gain sits in the company's corporate profit tax world, and extracting the proceeds to the owner is its own taxable step. If the owner sells the company, that is a disposal of a shareholding — a capital gain of the individual with its own basis rules (Article 37e), and, for the buyer, a purchase of the company's entire history. Neither route is generically better; what is generic is that the choice was effectively made at purchase, which is precisely the "plan the exit at the entrance" point this page exists to make. The corporate side's wider context sits in our tax and accounting guide.
