# Turkish Tax and Accounting System – A Practical Q&A Guide for Foreign Companies (2026)

Understanding Turkey’s accounting and tax framework requires more than knowing headline tax rates. The system combines **statutory accounting rules**, **tax-driven measurement principles**, and **regulatory filing obligations** that materially affect financial reporting, cash flow, and compliance risk.

This guide addresses the most frequently asked technical questions we receive from foreign-owned companies, regional headquarters, and cross-border groups entering or operating in Turkey.

## 1\. Accounting Standards in Turkey

### Which accounting standards apply in practice (IFRS, TFRS, BOBİ FRS)?

Turkey operates a **multi-tier accounting standards system**, where the applicable framework depends primarily on **public interest status, company size, and regulatory oversight**.

### Applicable frameworks

| Company Type | Applicable Standards |
| --- | --- |
| Listed companies, banks, insurance companies, financial institutions | **TFRS** (Turkish Financial Reporting Standards – fully aligned with IFRS) |
| Large and medium-sized non-public companies | **BOBİ FRS** |
| Small entities not subject to audit | Local statutory accounting rules under the Tax Procedure Law |

**Key points:**

* **TFRS = IFRS in substance**, with Turkish translations and implementation guidance.
    
* **BOBİ FRS** is a simplified accrual-based framework but still materially more robust than pure tax accounting.
    
* Companies subject to **independent statutory audit** generally fall under either TFRS or BOBİ FRS.
    

**Sector impact:**  
Financial services, capital markets, insurance, and payment institutions are almost always required to apply TFRS regardless of size.

## 2\. Chart of Accounts

### Is the Turkish Uniform Chart of Accounts mandatory?

Yes. The **Turkish Uniform Chart of Accounts (Tekdüzen Hesap Planı)** is **mandatory for statutory bookkeeping and tax reporting**.

### Practical flexibility

* Companies may **open sub-accounts freely** under mandatory account codes.
    
* Management reporting, IFRS consolidation packs, and group reporting may use **parallel mappings**.
    
* ERP systems typically maintain **dual structures**: statutory chart + group reporting structure.
    

### Key differences from international charts

* Tax-driven account logic (e.g., non-deductible expenses tracked separately).
    
* Detailed VAT and withholding tax accounts embedded in the chart.
    
* Balance-sheet orientation aligned with tax audits rather than investor reporting.

## 3\. Main Taxes and Tax Rates

### What are the principal corporate taxes in Turkey?

| Tax | Standard Rate | Key Notes |
| --- | --- | --- |
| Corporate Income Tax | **25%** | Calculated on statutory profit adjusted for tax add-backs |
| Value Added Tax (VAT) | **1%, 10%, 20%** | Standard rate: 20% |
| Withholding Tax | **0%–20%** | Depends on income type |
| Stamp Duty | Up to **0.948%** | Applies to contracts and agreements |
| Social Security Contributions | ~**37.5%** employer+employee | Calculated on gross salary |

**Accounting treatment:**  
Taxes are generally recognized on an **accrual basis**, but deductibility is determined strictly by tax law.

---

## 4\. Inventory Valuation

### Which inventory valuation methods are permitted?

For statutory and tax purposes, the following are acceptable:

* **Weighted average**
    
* **Moving average**
    
* **FIFO**
    

**LIFO is not permitted.**

### Standard costing

* **Not acceptable for statutory or tax reporting**
    
* Allowed only for **internal management and budgeting**
    
* Year-end inventories must be converted to actual cost for statutory books
    

---

## 5\. Fixed Assets and Depreciation

### How are fixed assets recognized and depreciated?

**Recognition threshold:**  
Assets with useful lives exceeding one year are capitalized.

### Depreciation methods

* **Straight-line** (most common)
    
* **Declining balance** (limited use)
    

### Useful lives

* Determined primarily by **tax legislation**, not management judgment
    
* Tax authorities publish depreciation tables by asset class
    

**Important practical point:**  
Even companies reporting under IFRS or BOBİ FRS usually **align depreciation with tax rules** to avoid permanent differences.

---

## 6\. Foreign Currency Accounting

### How are foreign currency transactions treated?

* Initial recognition at **CBRT exchange rate** on transaction date
    
* Year-end remeasurement of:
    
    * Cash
        
    * Receivables
        
    * Payables
        

### Exchange differences

* Recognized in **profit or loss**
    
* Fully **taxable or deductible**
    
* Unrealized FX gains are taxable at year-end
    

This makes FX exposure a **direct cash-tax issue**, not merely an accounting one.

---

## 7\. Revenue Recognition

### What principles apply to revenue recognition?

Under statutory rules:

* **Goods:** Revenue recognized upon delivery and control transfer
    
* **Services:** Recognized when service is completed or measurable progress exists
    

Under TFRS / BOBİ FRS:

* Accrual-based recognition aligned with performance obligations
    
* Long-term service contracts may require **percentage-of-completion**
    

Tax authorities often prioritize **invoice date and delivery documentation** in audits.

---

## 8\. Statutory Financial Statements

### Which financial statements are required?

At a minimum:

* Balance Sheet
    
* Income Statement
    
* Notes to the Financial Statements
    

Additional statements (depending on framework):

* Cash Flow Statement
    
* Statement of Changes in Equity
    

Statements must be prepared **annually** and retained for tax inspection.

---

## 9\. Statutory Audit Requirements

### When is statutory audit mandatory?

Companies exceeding **two of the following three thresholds** are generally subject to audit:

* Total assets
    
* Net sales revenue
    
* Number of employees
    

Sector-specific rules apply to:

* Financial institutions
    
* Energy companies
    
* Public interest entities
    

### Auditing standards

* Audits are conducted under **Turkish Auditing Standards**, aligned with ISA.
    

---

## 10\. Related-Party Transactions

### What disclosures and documentation are required?

**Disclosure requirements:**

* Related-party balances
    
* Nature of transactions
    
* Pricing principles
    

**Transfer pricing documentation:**

* Annual transfer pricing report
    
* Comparable analysis
    
* Intragroup agreements
    

Turkey follows the **OECD transfer pricing framework**, with increasing audit scrutiny.

---

## 11\. Tax Filing and Compliance Calendar

### What are the main tax filings and frequencies?

| Obligation | Frequency |
| --- | --- |
| VAT Returns | Monthly |
| Withholding Tax Returns | Monthly |
| Social Security Filings | Monthly |
| Corporate Tax Prepayments | Quarterly |
| Annual Corporate Tax Return | Annually |

Late filings result in **automatic penalties and interest**, with limited discretion.

---

## Final Considerations

Turkey’s accounting and tax system is **technically robust but compliance-intensive**. The primary risk for foreign companies is not tax rates, but:

* Incorrect accounting framework selection
    
* Misalignment between statutory books and group reporting
    
* Underestimating tax-driven accounting adjustments
    

A properly designed accounting architecture at entry stage materially reduces audit risk and long-term compliance cost.

**If you are evaluating market entry, restructuring your Turkish subsidiary, or aligning statutory accounting with IFRS group reporting, a tailored technical assessment is strongly recommended before incorporation or acquisition.**
