Tax When a Foreign Shareholder Sells Shares in a Turkish Company: AŞ vs Ltd, 2-Year Rule and Treaty Capital Gains
Foreign Shareholder Share Sale Tax in Turkey: Tax when a foreign shareholder sells shares in a Turkish company: AŞ share certificates, Ltd company interests, two-year rule, non-resident individuals and companies, treaty capital-gains
The Turkish tax result when a foreign shareholder sells an interest in a Turkish company depends on who the seller is, what type of company/share is being sold, how long the interest was held, whether an AŞ share is represented by qualifying share certificates and what the applicable double-tax treaty says. For an individual, Turkish Income Tax Law treats disposal of partnership rights/interests as capital-gain income, while qualifying shares of a Turkish resident company represented by share certificates and held for more than two years can fall outside the individual capital-gain rule. A limited-company interest is legally different from an AŞ share certificate and should not be given the two-year share-certificate exemption automatically. A non-resident corporate seller is analysed under Corporate Tax Law limited-taxpayer rules and the relevant treaty. The share-transfer formalities and the tax treatment must therefore be audited together before signing.
Foreign shareholder exit map
| Seller / asset | Domestic-law starting point | Key tax question |
|---|---|---|
| Non-resident individual – AŞ share certificate | Capital-gains rules; qualifying >2-year share certificate can fall outside taxable category | Was a legally valid share certificate issued and held long enough? |
| Non-resident individual – Ltd company interest | Partnership-right disposal can be taxable capital gain | Do not import AŞ share-certificate exemption mechanically. |
| Foreign corporate shareholder | Limited-taxpayer corporate gain / special declaration rules | Domestic source rule plus treaty Article 13. |
| Treaty resident seller | Treaty may allocate taxing right differently | Residence certificate, property-rich company clauses and holding-period wording. |
| Sale price paid abroad | Does not by itself eliminate Turkish-source analysis | Source and treaty depend on the Turkish company interest, not payment location alone. |
1. Tax analysis begins with the legal form of the seller and the equity instrument
A share transfer can look commercially identical while producing different Turkish tax results. The seller can be an individual or a foreign company. The target can be a Turkish joint-stock company or limited company. An AŞ interest can be represented by a printed share certificate, a temporary certificate or merely book-entry/share records depending on the facts.
These distinctions matter because Turkish tax exemptions refer to specific legal instruments. A tax opinion should not use the generic English word “shares” and assume all company interests are treated identically.
The acquisition and transfer documents should therefore be reviewed before the purchase price is finalised.
2. A non-resident individual can have Turkish-source capital-gain exposure
Income Tax Law taxes limited taxpayers on Turkish-source income. Disposal of rights or interests connected with a Turkish company can fall within the value-increase/capital-gain provisions.
The fact that the seller lives permanently abroad or receives the price in a foreign account does not by itself move the Turkish company interest outside Turkish source rules.
The exact domestic result is then modified where a double-tax treaty applies.
3. AŞ shares can receive different tax treatment from limited-company interests
The Income Tax Law expressly excludes from the capital-gains category qualifying shares of a Turkish resident company that are represented by share certificates and held for more than two years, subject to the statutory conditions.
This rule is often important for foreign founders and investors exiting a privately held Turkish AŞ.
However, the legal existence and acquisition date of the certificate must be proved. A company cannot safely print a certificate immediately before sale and treat the investor as though that certificate had been held for years.
4. The share certificate is not merely a piece of paper for tax purposes
Corporate records should show a valid issuance. Board/shareholder records, certificate serial numbers, share ledger entries and delivery/acquisition evidence can matter.
Temporary certificates that legally stand in place of share certificates can require separate analysis under the tax rules and established Revenue Administration practice.
The seller should preserve the original corporate records, not only a scanned certificate.
5. The two-year holding period must be proved from the correct acquisition event
Revenue Administration guidance and rulings apply the two-year rule to qualifying shares held for more than two years. The acquisition date of the share and the date the qualifying certificate was acquired/issued in the legally relevant manner should be documented.
Capital increases, bonus shares, mergers and other reorganisations can complicate the holding-period calculation.
Do not use the company’s incorporation date automatically as the shareholder’s acquisition date.
6. A Turkish limited-company interest is not the same as an AŞ share certificate
Limited companies have partnership interests, but the tax rule excluding certain AŞ share certificates after two years should not be copied mechanically to Ltd interests.
A non-resident individual selling a limited-company interest can therefore have a taxable value-increase gain under domestic law, subject to treaty relief and calculation rules.
The site’s existing company formation and share transfer guide explains corporate transfer formalities separately.
7. Taxable gain is based on net gain, not gross sale price
Where the sale is taxable, the acquisition cost and eligible selling expenses reduce the gain under the applicable income-tax rules.
Purchase agreements, bank payment proof, capital contribution records and documented fees should be retained.
An undocumented acquisition cost can make the taxable calculation substantially worse.
8. Statutory cost indexation can be relevant
Turkish capital-gain rules permit cost adjustment/indexation in qualifying cases where the statutory inflation-index threshold is met. The exact calculation uses official producer-price data and statutory rules.
This can materially reduce nominal gains caused by inflation.
The calculation should be performed for the actual acquisition and disposal months rather than using an informal currency comparison.
9. The 2026 annual capital-gain exemption may apply to qualifying individual gains
The Revenue Administration’s 2026 other-gains guidance states a 150,000 TL annual exemption for qualifying capital gains within the relevant category.
The exemption is applied to net taxable gain and does not transform an otherwise commercial securities-trading activity into exempt personal investment.
Specific securities governed by other tax regimes can have different treatment.
10. A foreign corporate shareholder is analysed under Corporate Tax Law
A company incorporated and managed abroad is generally a limited corporate taxpayer in Türkiye. A gain from disposal of a Turkish company interest can constitute Turkish-source corporate income depending on the statutory source rules.
Corporate sellers should not use the individual Income Tax Law two-year share-certificate rule without confirming that the corporate tax framework provides equivalent treatment; it is a different taxpayer regime.
Tax treaties can be particularly important for a foreign corporate investor.
11. A non-resident corporate seller can face a special declaration procedure
Corporate Tax Law contains special declaration rules for certain other gains and income obtained by limited taxpayers without an ordinary Turkish permanent establishment.
Revenue Administration rulings refer to special filing timelines and competent tax offices for gains from Turkish assets/rights in qualifying circumstances.
The seller should determine the filing obligation before closing rather than after funds leave Türkiye.
12. The treaty capital-gains article can override domestic source taxation
Many double-tax treaties contain Article 13-style provisions allocating gains from shares. Some reserve taxation to the seller’s residence state, while others allow Türkiye to tax shares in property-rich companies or gains where specified participation/holding-period conditions exist.
There is no single treaty rule for all countries. Protocol amendments can also change older treaty language.
The seller should obtain a valid residence certificate and use the exact treaty in force for the sale date.
13. Property-rich company provisions can preserve Turkish taxing rights
Modern treaties frequently allow the state where immovable property is located to tax gains from shares whose value is derived mainly from that property.
This can be important where a foreign shareholder sells a Turkish company whose primary asset is real estate, a hotel, development land or an investment property portfolio.
A seller should not assume a treaty’s ordinary share-gain exemption applies without checking the property-rich clause.
14. Offshore payment does not determine source by itself
Parties can agree that the buyer pays the foreign seller outside Türkiye. That payment location is a banking arrangement, not automatically a tax-source rule.
The asset sold remains an interest in a Turkish company and Turkish domestic/treaty rules determine tax.
Payment routing should also be consistent with foreign-exchange, banking and KYC documentation.
15. Deferred price, earn-out and escrow need tax timing analysis
International share deals often split price into closing payment, escrow, retention and future earn-out. The Turkish tax timing of each component depends on when the gain is legally realised under the applicable rules.
The sale agreement should state objective calculation and payment conditions.
An earn-out should not be left undefined if the seller’s tax return depends on it.
16. Tax planning cannot replace valid Turkish company transfer formalities
A Ltd share transfer can require notarised agreement and registration/approval steps under Turkish company law depending on the circumstances. AŞ transfers use different rules based on share type, restrictions and corporate records.
The tax closing date should correspond with the legal transfer date.
Side letters should not create a different economic transfer date from the official records without analysis.
17. A clean exit file protects both tax and corporate positions
Keep acquisition contract, payment proof, share certificates, share ledger, capital increase records, sale agreement, price payment, tax-residence certificate, treaty analysis and any filing/payment evidence.
Foreign corporate sellers should also retain corporate authority documents and beneficial-owner/KYC material.

Conclusion
The tax on selling a Turkish company interest cannot be determined from the headline “held for two years.” The legal form of the company, the existence of an AŞ share certificate, seller type, acquisition history and treaty must all be checked before the gain is classified.
Frequently asked questions
Does every share held for two years become tax-free?
No. The well-known two-year individual rule concerns qualifying shares of a Turkish resident company represented by share certificates; company form and certificate status matter.
Does it automatically apply to Ltd company interests?
No.
Does a foreign seller pay tax if paid abroad?
Payment location alone does not determine Turkish source or treaty taxing rights.
Can a tax treaty exempt the gain in Turkey?
Yes in some treaties and circumstances, but property-rich and other clauses must be checked.
Does a residence certificate matter?
Yes for claiming treaty treatment.
What is the 2026 general capital-gain exemption?
Revenue Administration guidance states 150,000 TL for qualifying 2026 value-increase gains.
Can acquisition cost be deducted?
Yes under the applicable calculation rules when properly documented.
Can cost indexation apply?
It can apply where statutory conditions are met.
Does a foreign company seller use the individual exemption?
No. Corporate sellers are analysed under the Corporate Tax Law and treaty rules.
Should tax be checked before the share purchase agreement is signed?
Yes. The seller’s net proceeds can change materially.
