​Tax Compliance and Tax Planning Lawyer in Istanbul, Turkey

Tax Compliance and Tax Planning Law in Türkiye

Tax compliance and tax planning are closely connected, but they answer different questions.

​

Tax compliance is about meeting the obligations imposed by Turkish tax law. Depending on the business, these may include registration, accounting records, invoicing, VAT, withholding, declarations, payments, electronic systems, documentation and responses to tax administration procedures.

​

Tax planning takes place earlier. It asks how a proposed transaction, investment, financing arrangement or business structure can be organised while remaining within the applicable legal framework.

​

For example, a business considering an international service agreement may want to understand the tax treatment before the agreement is signed. A company planning to acquire another business may need to consider the tax consequences of the proposed acquisition structure before the transaction documents are finalised.

​

Good tax planning is not simply about finding the lowest possible tax burden. A structure also needs to make commercial sense, reflect the real relationship between the parties and satisfy the requirements of Turkish law.

​

What Does a Tax Lawyer in Istanbul Do?

Tax work often sits at the intersection of law, business and finance.

​

A Turkish tax lawyer may become involved when a company is:

​

• Establishing a business in Türkiye

• Restructuring its corporate group

• Entering into a major commercial contract

• Acquiring or selling a company

• Financing an investment

• Making payments to an overseas group company

• Licensing intellectual property

• Employing people in Türkiye

• Buying or selling real estate

• Expanding into another jurisdiction

• Dealing with related-party transactions

• Preparing for a tax inspection

• Challenging a tax assessment or penalty

 

The exact advice depends on the facts. There is rarely a useful one-size-fits-all answer in tax law.

​

Main Areas of Turkish Tax Compliance

​

Corporate Tax

Turkish companies may be subject to corporate income tax under the Corporate Tax Law No. 5520.

​

Corporate tax advice can involve questions about taxable income, deductible expenses, exemptions, withholding, related-party transactions, reorganisations and cross-border arrangements.

 

The Corporate Tax Law and related tax legislation available through the Turkish Revenue Administration should be considered together with applicable communiqués and administrative guidance.

 

For a company, however, the statutory tax rate is only one part of the picture. The way the company earns income, incurs expenses, finances its activities and deals with related parties may be equally important.

​

Income Tax

Individuals may encounter Turkish income tax rules in connection with employment, commercial activities, professional services, rental income, investments and other forms of income.

​

Residence can also matter.

 

A person living or working between Türkiye and another country may need an analysis of both domestic rules and any applicable double taxation agreement.

 

The Turkish Revenue Administration publishes official rulings and guidance concerning income earned by residents and non-residents. Its published rulings illustrate how the treatment of particular cross-border income can depend on both Turkish legislation and an applicable treaty.

​

Value Added Tax

VAT is an important consideration in many Turkish commercial transactions.

​

The VAT analysis can depend on:

​

• What is being supplied

• Where the supply takes place

• Who the parties are

• Whether the transaction involves goods or services

• Whether a special regime applies

• Whether an exemption is available

• Whether the transaction involves imports or exports

• What documentation supports the transaction

 

A contract should therefore not be reviewed only from a commercial perspective. Its VAT consequences can also deserve attention before signature.

​

Withholding Tax

Withholding can arise in various situations, including certain payments to employees, professionals, landlords, shareholders and foreign service providers.

Cross-border payments require particular care because Turkish domestic rules may interact with a double taxation agreement.

​

The Turkish Revenue Administration publishes specific rulings dealing with cross-border payments and treaty questions. For example, its published 2025 ruling concerning services purchased from a UK-resident company examines both Turkish corporate tax rules and the Türkiye–UK tax treaty.

​

Stamp Tax

Commercial agreements and other documents can create stamp tax considerations.

​

This can be particularly relevant in transactions involving several agreements, guarantees, financing documents or high-value contractual commitments.

​

The tax position should be considered before execution where the form and content of the documents may affect the applicable treatment.

​

Tax Planning for Companies in Türkiye

Tax planning is most useful when it forms part of the commercial decision-making process.

​

Before establishing a business or entering into a substantial transaction, it can be helpful to consider:

​

• Who will own the business?

• Where will the business operate?

• Which entity will enter into the contracts?

• Where will employees perform their work?

• Where will intellectual property be owned?

• How will the business be financed?

• Where will profits arise?

• How will profits be distributed?

• Will related companies provide services?

• Will payments cross borders?

• Which taxes may arise?

• What records will be needed to support the position?

 

These questions can often be answered more effectively before the structure is implemented.

​

Choosing a Business Structure and Considering Tax

The legal form of a business can influence how its activities are organised and taxed.

​

A foreign investor entering Türkiye may consider a Turkish subsidiary, branch or another legally appropriate structure depending on the commercial circumstances.

​

The analysis should not be reduced to tax alone. Corporate governance, liability, management, financing, employment, licensing and the eventual exit from the investment can all matter.

​

The Turkish Ministry of Trade provides official information concerning commercial companies and Turkish commercial legislation. Company registration and related changes are supported through MERSİS, the Ministry's central registration system for companies and commercial enterprises.

​

Tax Planning for Foreign Investors in Istanbul

Istanbul is a major centre for international business, and foreign investors may encounter Turkish tax issues at several stages of their investment.

​

These may include:

​

• Establishing a Turkish company

• Acquiring shares in a Turkish company

• Buying Turkish real estate

• Employing personnel

• Receiving dividends

• Receiving interest

• Licensing intellectual property

• Providing services to Turkish companies

• Financing a Turkish subsidiary

• Selling or restructuring a Turkish investment

 

The tax analysis may also involve the investor's home jurisdiction.

 

For this reason, international tax planning often requires looking at both Turkish domestic law and the applicable treaty framework.

 

Türkiye maintains a network of double taxation agreements, and the Turkish Revenue Administration publishes treaty-related information and material concerning the Mutual Agreement Procedure.

​

Double Taxation Agreements

A tax treaty can become important when income or business activities have a connection with more than one country.

​

Depending on the circumstances, questions may include:

​

• Which country can tax the income?

• Is withholding tax limited by the treaty?

• Does a permanent establishment exist?

• Where is the recipient resident?

• What type of income is involved?

• Are treaty relief requirements satisfied?

• Is there a mechanism for resolving double taxation?

 

The relevant treaty should always be examined rather than assuming that all international payments receive the same treatment.

 

The Turkish Revenue Administration's international tax resources provide treaty information and related materials. Its published resources also include information on the Mutual Agreement Procedure, which can be relevant when taxation by two jurisdictions gives rise to a treaty issue.

​

Transfer Pricing in Türkiye

Transfer pricing becomes important when related parties transact with one another.

A Turkish company may, for example, purchase services from an overseas group company, sell products to a related distributor, pay royalties to a group entity or receive financing from a related party.

​

The key question is whether the pricing and conditions are consistent with the applicable arm's-length framework.

​

A transfer pricing review may consider:

​

Functions

Who actually performs the relevant work?

​

Assets

Which entity owns or uses the relevant assets and intellectual property?

​

Risks

Which party actually assumes commercial and financial risks?

​

Contractual Terms

What do the agreements say, and do they reflect the way the parties operate in practice?

​

Pricing Method

Which pricing method is appropriate for the particular transaction?

​

Documentation

Can the company explain and support its position with reliable records?

​

The Turkish Revenue Administration's official transfer pricing materials should be consulted for the rules and documentation applicable to the relevant taxpayer and transaction.

​

International Payments and Tax Compliance

Cross-border payments deserve particular attention because several areas of law may overlap.

​

A payment from a Turkish company to an overseas entity may require consideration of:

​

• The nature of the payment

• Turkish withholding rules

• The recipient's tax residence

• A relevant tax treaty

• Permanent establishment issues

• Transfer pricing

• VAT

• Supporting documentation

• Beneficial ownership considerations where relevant

• Contractual substance

 

For example, the tax treatment of an overseas consultancy fee may differ from that of interest, royalties, dividends or the purchase of goods.

 

The Turkish Revenue Administration's published rulings demonstrate why the precise nature of a payment and the circumstances in which the service is performed can matter.

​

Tax Compliance for Related-Party Transactions

Related-party transactions should be approached carefully from both commercial and tax perspectives.

​

Examples include:

​

• Management services

• Consultancy

• IT services

• Financing

• Guarantees

• Intellectual property licensing

• Procurement

• Distribution

• Cost-sharing arrangements

• Intercompany sales

 

A well-drafted agreement is helpful, but the agreement should correspond with what actually happens.

 

Where the contract says one thing while the parties operate differently in practice, the documentation may not adequately support the intended tax treatment.

​

Tax Planning in Mergers and Acquisitions

M&A transactions can create tax questions before the parties reach closing.

​

Before Signing

A legal and tax review may examine:

​

• Historical tax liabilities

• Tax assessments

• Ongoing tax disputes

• VAT exposure

• Withholding

• Related-party transactions

• Transfer pricing

• Tax incentives

• Existing financing

• Real estate

• Intellectual property

• Corporate structure

​

In the Transaction Documents

Tax issues may be reflected in:

​

• Representations and warranties

• Tax covenants

• Indemnities

• Conditions precedent

• Purchase price adjustments

• Completion accounts

• Disclosure schedules

​

After Closing

The buyer may need to consider:

​

• Group restructuring

• Intercompany arrangements

• Financing

• Profit distribution

• Tax registrations

• Transfer pricing

• Ongoing compliance

 

This is why tax advice can be more valuable when it starts during due diligence rather than after the acquisition has closed.

​

Tax Considerations in Corporate Restructuring

Businesses sometimes need to reorganise because of growth, investment, financing or changes in ownership.

​

Restructuring may involve:

​

• Mergers

• Demergers

• Share transfers

• Asset transfers

• Capital increases

• Capital reductions

• Changes in ownership

• Group reorganisations

• Liquidation

 

The tax consequences can depend on the exact legal steps used to achieve the restructuring.

 

The Turkish Ministry of Trade's company and commercial registry resources and MERSİS can be useful official sources for the corporate-registration side of these changes.

​

Tax Planning for Financing Transactions

Financing can create tax issues involving interest, withholding, related-party transactions, documentation and the structure of the lender-borrower relationship.

​

This can arise in:

​

• Bank financing

• Shareholder loans

• Intercompany loans

• Cross-border financing

• Acquisition financing

• Project finance

• Corporate guarantees

 

A financing structure should be reviewed as a whole. The tax consequences should be considered alongside banking and finance law, corporate law and the underlying commercial purpose.

​

Tax Issues in Real Estate Transactions

Real estate transactions can involve several different tax considerations.

​

Depending on the circumstances, the analysis may cover:

​

• Purchase and sale

• VAT

• Rental income

• Capital gains

• Corporate taxation

• Withholding

• Property-related transaction costs

• Development projects

• Construction arrangements

• Corporate ownership

• Foreign ownership

 

The answer can change depending on whether the property is residential, commercial, investment property, development land or part of a larger business transaction.

 

For property transactions, tax planning should therefore be integrated with the underlying real estate and corporate advice.

​

Tax Planning for Intellectual Property and Technology Businesses

Technology businesses often have tax questions that do not arise in the same way for traditional businesses.

​

These may involve:

​

• Software licensing

• Intellectual property ownership

• Royalties

• Technology services

• R&D activities

• Cross-border development

• Intercompany licensing

• Employee arrangements

• International service agreements

 

The tax position should be considered together with Turkish intellectual property, technology and contractual law.

​

Tax Compliance for Employers

Businesses employing people in Türkiye have tax-related responsibilities connected with employment.

​

These can include:

​

• Payroll withholding

• Employee declarations

• Employment documentation

• Benefits

• Payments to employees

• Cross-border employee arrangements

 

Where an employee works across borders, the analysis may also involve residence, treaty provisions and the location where the work is performed.

 

Employment tax matters may therefore require coordination between tax, employment and social security advisers.

​

Electronic Tax Compliance in Türkiye

Tax administration in Türkiye is increasingly digital.

​

The Digital Tax Office provides taxpayers with electronic services including payments, document verification and tax calculations.

​

The Turkish Revenue Administration also operates electronic systems covering areas such as:

​

• e-Fatura

• e-Arşiv Fatura

• e-İrsaliye

• e-Defter

• e-Beyanname

• e-Tebligat

• Other electronic tax services

 

The administration's own materials describe these electronic systems as part of the digitalisation of tax administration.

 

The e-Beyanname system provides facilities for preparing and submitting electronic tax declarations, together with access to tax legislation, guidance and taxpayer resources.

 

Electronic compliance is therefore not merely an accounting issue. Companies should understand which systems apply to them and whether their internal processes support the required documentation.

​

Tax Records and Supporting Documents

A tax position is much easier to defend when the underlying documents tell a consistent story.

​

Depending on the business, relevant records may include:

​

• Contracts

• Invoices

• Bank statements

• Corporate resolutions

• Purchase orders

• Delivery documents

• Import and export documents

• Employment records

• Intercompany agreements

• Transfer pricing records

• Payment evidence

• Tax declarations

• Correspondence with tax authorities

 

The purpose is not simply to accumulate paperwork. The documents should help explain what happened, why it happened and how the tax treatment was determined.

​

Tax Audits and Tax Inspections

A tax inspection can be stressful for a business, particularly when the company is uncertain about what the authorities are examining.

​

Legal assistance may involve reviewing:

​

• The scope of the inspection

• The underlying transaction

• Accounting records

• Supporting documents

• Tax calculations

• Administrative correspondence

• Potential penalties

• The taxpayer's procedural rights

• Available responses and remedies

 

A company should generally avoid treating a tax inspection as merely an accounting exercise where the issue involves interpretation of law, contractual substance or a potential dispute.

​

Tax Assessments, Penalties and Disputes

A tax assessment or penalty can raise both substantive and procedural questions.

​

Depending on the circumstances, legal analysis may consider:

​

• Whether the assessment has a legal basis

• Whether the tax authority interpreted the transaction correctly

• Whether the taxpayer's documentation supports its position

• Whether the applicable procedure was followed

• Whether a penalty is justified

• Whether reconciliation or another administrative mechanism is available

• Whether judicial review should be pursued

 

The appropriate response depends on the assessment and the applicable procedural deadlines.

​

The Official Gazette is particularly important when checking the current wording of legislation and newly published amendments. Recent issues demonstrate that tax legislation and tax-related communiqués continue to change over time.

​

Tax Incentives and Exemptions

Türkiye's tax legislation contains various exemptions, deductions and incentive mechanisms.

​

The availability of a particular benefit depends on the taxpayer, activity, transaction and statutory conditions.

 

Before relying on an incentive, a business should consider:

​

• Whether it qualifies

• What conditions must be satisfied

• Whether an application is required

• What records must be maintained

• Whether reporting obligations apply

• How long the benefit remains available

• What happens if the conditions are not maintained

 

The relevant legislation and current administrative guidance should be checked rather than relying on an old description of an incentive.

​

Tax Planning for Startups

Tax planning is not reserved for large corporations.

​

For a startup, useful questions can arise when:

​

• Founders establish the company

• New investors join

• Shares are transferred

• Overseas investors provide funding

• Employees receive equity-related benefits

• The business begins selling internationally

• Intellectual property is licensed

• A foreign group company provides services

• The company establishes an overseas subsidiary

 

Addressing these issues early can be considerably easier than trying to restructure an arrangement after the money has moved or contracts have already been signed.

​

Tax Planning for International Groups

An international group operating through a Turkish company may need to coordinate Turkish compliance with the group's wider tax structure.

​

Typical areas include:

​

• Management services

• Group financing

• Royalties

• Intellectual property

• Procurement

• Distribution

• Intercompany sales

• Cost allocation

• Transfer pricing

• Dividends

• Withholding

• VAT

• Permanent establishment

 

The Turkish entity's actual activities, people, assets and risks should be considered alongside the written intercompany agreements.

​

Permanent Establishment Considerations

A foreign business can sometimes create Turkish tax questions without incorporating a conventional Turkish company.

​

For example, the activities of personnel, agents, offices or other business arrangements may require consideration of whether the foreign enterprise has created a taxable presence in Türkiye.

 

The answer depends on the applicable Turkish rules and, where relevant, the relevant tax treaty.

 

This is one reason why international businesses should consider tax implications before expanding their physical or operational presence in Türkiye.

​

Tax Compliance and Business Contracts

Tax issues can sometimes be identified simply by looking more carefully at the contract.

​

A commercial agreement may need to address matters such as:

​

• VAT

• Withholding

• Gross-up provisions

• Tax documentation

• Payment obligations

• Tax residence

• Allocation of transaction taxes

• Indemnities

• Compliance responsibilities

 

For an international agreement, the parties may also need to consider which country's tax rules apply to particular payments.

 

A contract that works commercially may still require adjustment if its tax consequences have not been considered.

​

Tax Advice for Foreign Entrepreneurs in Istanbul

Foreign entrepreneurs often have questions about how their personal circumstances interact with their Turkish business.

​

Depending on the facts, the analysis may involve:

​

• Tax residence

• Salary

• Dividends

• Director remuneration

• Shareholder loans

• Rental income

• Investment income

• Turkish-source income

• Treaty provisions

• Withholding

 

There is no universal answer for every foreign entrepreneur. The relevant facts and applicable law need to be examined together.

 

The Turkish Revenue Administration's official taxpayer resources include information relevant to residents, non-residents and international taxation. Its published rulings also demonstrate that cross-border tax questions can depend heavily on the precise circumstances of the taxpayer and income.

​

Working with Accountants and Financial Advisers

Tax lawyers and accountants often work together, but their roles are not identical.

​

An accountant or financial adviser may handle matters such as:

​

• Bookkeeping

• Accounting records

• Financial statements

• Tax calculations

• Returns

• Financial reporting

 

A tax lawyer may focus on:

​

• Interpretation of tax legislation

• Transaction structuring

• Contracts

• Corporate reorganisations

• International tax questions

• Administrative procedures

• Tax disputes

• Litigation

 

For complicated transactions, cooperation between the legal and financial teams can provide a more complete picture.

Tax Compliance and Tax Planning Lawyers in Istanbul

Kurucuk & Associates approaches Turkish tax matters from the perspective of the underlying business transaction.

​

We advise on tax compliance, tax planning, international taxation, transfer pricing, corporate transactions, cross-border payments, financing, restructuring, M&A and tax disputes, depending on the client's circumstances.

 

The starting point is not simply, "How much tax will this transaction cost?"

 

The more useful questions are often:

 

What is the client trying to achieve? How is the transaction actually going to work? Which entities are involved? Where are the activities performed? Where does the money move? Which documents support the arrangement? Which Turkish tax rules apply? And are there treaty or cross-border considerations?

 

That practical understanding can make tax advice more meaningful for the business.

 

For companies and investors operating in Istanbul or elsewhere in Türkiye, Kurucuk & Associates can coordinate tax-related legal work with broader corporate, commercial, M&A, banking and finance, project finance, international transactions and dispute resolution matters where those areas overlap.

Turkish tax legislation and administrative practice can change. The applicable position should therefore be checked against the legislation and official guidance in force at the time of the relevant transaction or filing.
