A company may be incorporated in one country, owned from a second and run by people sitting in a third. Tax residence does not automatically follow the certificate of incorporation. Where a company is actually managed can decide which state taxes its worldwide profit — and whether the same profit is taxed twice.
Under Article 3 of the Corporate Income Tax Law No. 5520, a company is a full taxpayer in Turkey if either its legal head office or its business centre is in Turkey. The business centre is defined as the centre where business operations are in fact concentrated and managed. A company registered abroad can therefore become taxable in Turkey on its worldwide profit if it is run from Turkey, and the resulting dual residence is resolved only by the tie-breaker clause of the applicable double taxation agreement — which differs from treaty to treaty.
How does Turkey decide whether a company is tax resident?
Turkish law applies two alternative connecting factors, and only one of them needs to be satisfied. The legal head office is the office designated in the articles of association and registered with the trade registry. The business centre is a question of fact: the place where the company’s transactions are actually concentrated and directed.
A company that meets either test is a full taxpayer and is assessed on income earned in Turkey and abroad. A company that meets neither is a limited taxpayer and is assessed only on income sourced in Turkey — in practice, through a permanent establishment, a permanent representative, or withholding at source.
| Connecting factor | Legal basis | Nature of the test | Consequence |
|---|---|---|---|
| Legal head office | Corporate Income Tax Law art. 3 | Formal — articles of association and registry record | Full liability on worldwide income |
| Business centre | Corporate Income Tax Law art. 3 | Factual — where operations are concentrated and managed | Full liability on worldwide income |
| Permanent establishment | Tax Procedure Law art. 156; treaty art. 5 | Factual — fixed place of business in Turkey | Limited liability on the profit attributable to it |
| Permanent representative | Income Tax Law art. 8 | Factual — a person acting for the foreign company | Limited liability on the related Turkish income |
The business centre test is close to, but not identical with, the treaty concept of place of effective management. It is a domestic rule with its own wording, applied by the tax administration on the facts of the file. A structure can satisfy the domestic test even where the group believes the treaty concept points elsewhere.
What does effective management and control actually mean?
No single element decides the question. Tax authorities and courts look at a pattern of behaviour over the period under review, and the pattern is usually visible in ordinary business records rather than in the corporate file.
Where commercial direction is set: budgets, pricing policy, market entry and exit, major investments, financing and group borrowing.
Where directors are physically located when they decide, how often they meet, who drafts the agenda, and whether resolutions record a genuine deliberation.
Who negotiates and signs contracts, who holds powers of attorney, and what the limits in the signature circular actually are.
Where payment instructions originate, who holds the tokens and mandates, and who approves transfers above the internal threshold.
Where senior management works day to day, where the staff performing the core function sit, and where the office actually is.
Where accounting is prepared and approved, where servers and systems are administered, and from which country the correspondence is sent.
The distinction that decides most files is between deciding and implementing. A local director who signs what has already been settled elsewhere is implementing. Conversely, a person who is not a director at all — a founder, a group executive, a shareholder representative — can be the person who effectively decides, and correspondence usually shows it.
Article 3 of the Tax Procedure Law requires tax provisions to be applied according to the true nature of the transaction, which may be proved by any evidence except witness statements. Board minutes are evidence, not a conclusion: they carry weight when they are consistent with travel records, calendars, e-mail traffic and payment approvals, and they lose weight when they are not.
How does dual residence arise in practice?
Pattern A — inbound exposure
A holding company is incorporated abroad by entrepreneurs who live in Istanbul. The registered office is a service address, the local director signs on instruction, and every commercial decision is taken in Turkey. The state of incorporation treats it as resident because it was formed there; Turkey may treat it as resident because its business centre is here. Both states can assess the same profit.
Pattern B — outbound exposure
A Turkish company is part of a foreign group. Its general manager reports to a regional office abroad, the budget is approved abroad and the bank mandates sit with group treasury. The other state may argue that the company is managed from its territory. The company remains resident in Turkey under the legal head office test, so the conflict is real and has to be resolved under the treaty.
Two points are worth separating. Shareholding is not management: a Turkish shareholder does not by itself make a foreign company resident in Turkey. And the opposite is also true — a fully foreign-owned company with no Turkish shareholder can still have its business centre in Turkey if that is where it is run.
What does a double taxation agreement do about it?
A treaty first defines residence by reference to domestic law: a person is a resident of a contracting state if it is liable to tax there by reason of domicile, residence, place of management or a similar criterion. A person taxable only on income sourced in that state is not a resident for treaty purposes. Where both states qualify under their own law, the tie-breaker applies — and its design varies.
| Tie-breaker design | Typical wording | Practical effect |
|---|---|---|
| Place of effective management | The company is deemed resident of the state in which its place of effective management is situated | Resolved by facts, without an application. Common in the older generation of treaties. |
| Mutual agreement | The competent authorities shall endeavour to determine residence by mutual agreement, having regard to the place of effective management, the place of incorporation and other relevant factors | Not self-executing. Until the authorities agree, treaty relief may be unavailable except to the extent they allow. Introduced in the 2017 revision of the OECD Model. |
| Incorporation or specific criteria | Residence follows the place of incorporation, or the treaty lists criteria in a fixed order | Predictable, and capable of producing a result the group did not expect. |
Article 4 of the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting replaces the automatic tie-breaker with a mutual agreement procedure. Turkey signed the convention on 7 June 2017 and, in its position at signature, entered a reservation covering the whole of Article 4. Turkey had not deposited its instrument of ratification as at the most recent status list published by the depositary, so the convention has not modified Turkey’s treaties. For Turkish treaties, the tie-breaker is still the one printed in the bilateral text, and the current status should be verified when the question is live.
What happens if the two states do not agree?
Where a treaty exists, the taxpayer can ask the competent authorities to resolve the conflict. Articles added to the Tax Procedure Law in 2021 regulate this process on the Turkish side: an application is made to the Revenue Administration on the ground that the taxpayer has been, or on strong indications will be, taxed contrary to the treaty. The application must be made within the period and in the form prescribed by the treaty concerned — in most Turkish treaties, within three years of the first notification of the measure — and it suspends the period for bringing the matter before the tax courts for the taxes and penalties within its scope.
- Apply on timeThe treaty period runs from notification of the assessment, not from the year in which the income arose.
- Keep the domestic route openFiling a return with a reservation, or preserving the right of appeal, protects the position while the authorities talk.
- Expect a negotiated, not an adjudicated, outcomeMost treaties oblige the authorities to endeavour to reach agreement; unless an arbitration clause applies, they are not obliged to succeed.
- Use the credit mechanism as a floorArticle 33 of the Corporate Income Tax Law allows foreign tax paid on foreign income to be credited against Turkish corporate income tax, capped at the Turkish tax on that income and subject to documents certified by the Turkish consulate in the country concerned.
What changes if a foreign company is treated as resident in Turkey?
Reclassification is not limited to a single assessment. It creates a full compliance history that was never filed.
- Corporate income tax returns for each open year, with statutory books kept in Turkish and in Turkish lira
- Entry into the electronic invoice and electronic ledger regime, with penalties where paper invoices were issued
- Transfer pricing documentation for every transaction with group companies, which now become related parties of a Turkish taxpayer
- Withholding obligations on payments abroad, including interest, royalties, services and dividends
- Tax loss penalty and late payment interest on the principal, and the risk of the reclassification being extended to earlier years within the statute
- Possible exposure to the global minimum tax rules where the group exceeds the consolidated revenue threshold
Is it a residence risk or a permanent establishment risk?
The two are frequently confused, and the difference is a matter of scale rather than of degree.
| Residence in Turkey | Permanent establishment in Turkey | |
|---|---|---|
| Trigger | Legal head office or business centre in Turkey | Fixed place of business, or a dependent agent habitually concluding contracts |
| Scope of tax | Worldwide profit of the company | Only the profit attributable to the establishment |
| Treaty route | Tie-breaker clause on residence | Article 5 and article 7 of the treaty |
| Typical evidence | Board practice, decision trail, bank authority | Premises, staff, contract negotiation, storage |
| Usual remedy | Relocate decision-making, or accept residence and plan for it | Define the local function, price it at arm’s length, register where required |
A liaison office is the clearest illustration. It is permitted to exist precisely because it does not trade; once it starts negotiating, invoicing or deciding, the question moves from formality to substance. The same logic applies to a foreign company whose local team has quietly grown into a management function. Our guides on liaison offices and branches set out the boundaries in more detail.
What should international groups document?
- Minutes that record where each participant was, what was discussed and what alternatives were considered — not only the decision reached
- An internal delegation matrix showing which decisions sit with the board, which with management, and above which threshold approval moves up
- Signature authority and powers of attorney that match the matrix, with no open-ended power held by a person outside the intended state of management
- Bank mandates and approval limits consistent with the same allocation
- Travel and calendar records covering the meeting dates, retained for the same period as the tax records
- Intra-group service agreements for functions genuinely performed from another country, priced on arm’s length terms and invoiced
- Certificates of residence obtained annually for each entity claiming treaty benefits, with the translation and legalisation the counterparty state requires
- A periodic review whenever directors change, a founder relocates, or a group reorganisation moves reporting lines
Turkish company law expressly permits board and shareholder meetings to be held by electronic means. That solves a corporate law question; it does not answer the tax question. Where every participant joins from the same country, the electronic format tends to confirm rather than dilute the location of management, so the participation record deserves the same care as the resolution itself.
Common pitfalls
- A local director appointed for appearance, with an undated resignation letter held by the group — one of the strongest indications that decisions are taken elsewhere
- Minutes prepared abroad, circulated for signature, and dated as though a meeting had taken place
- An e-mail trail in which the operative instruction consistently comes from the same city, followed by a formal resolution a week later
- A general power of attorney granted to a person resident in Turkey covering banking, contracts and personnel
- Treating a certificate of residence as proof of where management sits — it evidences liability to tax in the issuing state, nothing more
- Assuming that because a treaty exists, dual residence cannot cause double taxation
- Reorganising the structure after an audit has begun, which changes the future position but not the years under review
