How to Tax Your Prop Firm Profits in Turkey

Key Takeaways

Overview

Turkey (Türkiye) presents a moderate tax environment for prop firm traders, with progressive income tax rates reaching 40% on income above TRY 3,000,000 (~$85,000 at current exchange rates) and a relatively low social security burden for self-employed individuals. The Gelir İdaresi Başkanlığı (GİB) — Turkey's Revenue Administration — classifies prop firm payouts as serbest meslek kazancı (freelance/professional income) or ticari kazanç (commercial income), depending on the nature and regularity of the activity.

Turkey's most significant challenge for prop firm traders is not the tax rate itself but the extreme currency volatility of the Turkish Lira (TRY). The Lira has depreciated dramatically against the USD and EUR over the past decade, and prop traders receiving USD-denominated payouts face complex exchange rate accounting requirements. Conversely, this same volatility creates a paradoxical advantage: since tax brackets are denominated in TRY and prop firm payouts are earned in USD/EUR, a trader earning a consistent $5,000/month may find themselves in progressively lower TRY tax brackets as the Lira depreciates — effectively reducing their tax burden in real terms.

The Bağ-Kur social security system for self-employed individuals is mandatory but relatively modest compared to European equivalents, with monthly contributions based on declared income brackets. Turkey does not impose a wealth tax, and its VAT system (KDV) generally exempts financial services, making the overall burden manageable for prop traders.

How Prop Firm Income Is Classified

Serbest Meslek Kazancı (Freelance/Professional Income)

GİB classifies prop firm payouts as freelance professional income because:

• Personal expertise: The trader provides skilled trading services using personal knowledge
• Independence: No employment relationship exists with the prop firm
• Self-direction: The trader determines their own trading strategy and schedule
• Professional character: Trading requires specialized skills and ongoing development
• Service-based compensation: Payouts are for services rendered, not investment returns

Alternative: Ticari Kazanç (Commercial Income)

If the trader operates through a formal business entity or the activity has commercial characteristics (employees, office, multiple accounts):

Category	Description	When It Applies
Serbest meslek kazancı	Freelance/professional income	Individual traders, personal skill
Ticari kazanç	Commercial income	Business-scale operations
Menkul sermaye iradı	Securities income	❌ Does not apply
Değer artış kazancı	Capital gains	❌ Does not apply

Why Not Capital Gains

Turkey's capital gains provisions (değer artış kazancı) do not apply because:

• The trader does not invest personal capital
• No securities or assets are acquired or disposed of
• Payouts are service compensation, not investment returns
• The contractual relationship is a service agreement with a foreign entity

Tax Rates and Brackets

Gelir Vergisi (Income Tax) — Progressive Rates (2026)

Taxable Income (TRY)	Rate
0 – 110,000	15%
110,001 – 230,000	20%
230,001 – 580,000	27%
580,001 – 3,000,000	35%
Above 3,000,000	40%

Note: Brackets are adjusted annually for inflation. Given Turkey's high inflation environment, brackets may be substantially different by the time of filing.

The Currency Effect on Taxation

This is Turkey's most unique tax dynamic for prop traders:

Scenario: A trader earning $5,000/month throughout the year:

• If TRY/USD = 30 at start of year: $5,000 = TRY 150,000/month = TRY 1,800,000/year → 35% marginal bracket
• If TRY/USD = 35 at end of year: $5,000 = TRY 175,000/month
• Average for the year may vary significantly depending on monthly exchange rates

Turkish tax law requires conversion at the TCMB (Central Bank) exchange rate on the date of receipt. This creates:

• Complex monthly accounting requirements
• Potential for significant exchange rate gains or losses
• Variable effective tax rates depending on currency movements

Detailed Example Calculations

Example 1: Emerging Trader

Trader earning $20,000/year (~TRY 640,000 at 32 TRY/USD) with TRY 50,000 expenses:

• Taxable income: TRY 590,000
• Tax: TRY 16,500 + 24,000 + 94,500 + 3,500 = approximately TRY 138,500
• Bağ-Kur: approximately TRY 36,000/year
• Total: approximately TRY 174,500 (~$5,450)
• Effective rate: approximately 27.3%

Example 2: Established Trader

Trader earning $50,000/year (~TRY 1,600,000) with TRY 100,000 expenses:

• Taxable income: TRY 1,500,000
• Tax: approximately TRY 415,000
• Bağ-Kur: approximately TRY 48,000/year
• Total: approximately TRY 463,000 (~$14,470)
• Effective rate: approximately 28.9%

Example 3: High-Income Trader

Trader earning $100,000/year (~TRY 3,200,000) with TRY 200,000 expenses:

• Taxable income: TRY 3,000,000
• Tax: approximately TRY 882,000
• Bağ-Kur: approximately TRY 60,000/year (approaching cap)
• Total: approximately TRY 942,000 (~$29,440)
• Effective rate: approximately 29.4%

Bağ-Kur: Self-Employed Social Security

Mandatory Registration

All self-employed individuals in Turkey must register with the SGK (Sosyal Güvenlik Kurumu — Social Security Institution) under the 4/b (Bağ-Kur) category:

Component	Rate
Pension (emeklilik)	20%
Health (sağlık)	12.5%
Total	32.5%

However, this is calculated on the declared income base, not actual income:

• Minimum base: The minimum wage (asgari ücret) — TRY 20,002.50/month in 2025
• Maximum base: 7.5× minimum wage
• Most self-employed declare at or near the minimum base to minimize contributions

Practical Cost at Minimum Base

• Monthly contribution: approximately TRY 6,500 (32.5% of minimum wage)
• Annual contribution: approximately TRY 78,000
• If declared at minimum base regardless of actual income: effective rate is low for high earners

What Bağ-Kur Provides

• Pension: Retirement pension (emekli maaşı)
• Health insurance: Access to public healthcare (SGK sağlık)
• Disability pension: If applicable
• Survivor's pension: For dependents

The 5% Discount

Paying Bağ-Kur contributions on time (within the month) provides a 5% discount on the total contribution amount.

KDV (Katma Değer Vergisi — VAT)

Standard Rates

• Standard rate: 20% (increased from 18% in July 2023)
• Reduced rate: 10%
• Super-reduced rate: 1%
• Financial services: Generally exempt from KDV

Impact on Prop Traders

• Freelance professionals providing services to foreign entities: exempt from KDV (export of services — hizmet ihracatı istisnası)
• The trader issues a serbest meslek makbuzu (freelance receipt) with KDV exemption notation
• Input KDV on business expenses may be recoverable
• No KDV registration threshold exists — all freelance professionals must issue receipts

Hizmet İhracatı İstisnası (Export of Services Exemption)

To qualify for the KDV exemption on services to foreign entities:

1. The service must be provided to a foreign client
2. The service must benefit the foreign entity (not a Turkish establishment)
3. Payment must be received in foreign currency
4. The foreign currency must be brought into Turkey (döviz taahhütnamesi)

Prop firm payouts meet all criteria if the trader receives USD/EUR from a foreign prop firm into a Turkish bank account.

Deductible Expenses

Turkish tax law allows deduction of expenses related to earning income:

Fully Deductible

• Challenge and reset fees — payments to prop firms
• Trading platform subscriptions — TradingView, MetaTrader, trading journals
• VPS hosting — virtual private servers
• Accounting fees — mali müşavir (financial advisor) fees
• Professional education — trading courses, seminars, books
• Bank charges — international transfer fees
• Bağ-Kur contributions — social security payments
• Depreciation — business equipment

Proportionally Deductible

• Internet — business-use proportion
• Home office — Turkey allows deduction for a dedicated workspace (proportion of rent, utilities)
• Computer equipment — depreciated over useful life (computers: 3–5 years)
• Mobile phone — business-use proportion

Serbest Meslek Kazancı Special Provisions

Freelance professionals can deduct:

• Amortization of business assets
• Rent for a dedicated office/workspace
• Professional organization membership fees
• Travel expenses directly related to business

Stopaj (Withholding Tax)

General Rules

Turkey applies withholding tax (stopaj/tevkifat) at source on certain income types:

• Freelance professional income: 20% stopaj when paying entity is Turkish
• Foreign-source income: No Turkish stopaj (prop firm is foreign)

Since prop firms are foreign entities, no Turkish stopaj is withheld at source. The trader declares the full amount and pays tax through the annual return and quarterly advance payments.

Filing Requirements and Deadlines

Essential Registrations

• Vergi levhası — tax registration certificate (from the local vergi dairesi)
• SGK registration — social security (Bağ-Kur 4/b category)
• Serbest meslek defteri — freelance professional ledger (notarized)
• e-Devlet account — government digital services portal

Key Deadlines

Deadline	Description
March 1–31	Annual income tax return (yıllık gelir vergisi beyannamesi)
March 31, July 31	Tax payment installments (2 equal installments)
Quarterly	Geçici vergi (provisional/advance tax — 4 quarterly declarations)
Monthly	Bağ-Kur contributions

Geçici Vergi (Provisional Tax)

Quarterly advance tax declarations are mandatory:

Quarter	Declaration Deadline	Payment Deadline
Q1 (Jan–Mar)	May 17	May 17
Q2 (Apr–Jun)	August 17	August 17
Q3 (Jul–Sep)	November 17	November 17
Q4 (Oct–Dec)	February 17	February 17

Provisional tax is calculated at the normal progressive rates and credited against the annual tax liability.

Tax Year

Turkey uses the calendar year (January 1 – December 31). The annual return is filed during March of the following year.

Beyanname (Tax Return) Filing

Filing is done electronically through:

• Dijital Vergi Dairesi (Digital Tax Office) — GİB's online portal
• Through a mali müşavir (certified public accountant) — most common for self-employed

Record Keeping

Turkish tax law requires records for 5 years from the end of the year in which the return was filed. Prop traders should maintain:

• Serbest meslek makbuzları (freelance receipts) for all income
• Bank statements showing incoming transfers
• Exchange rate records (TCMB rates on receipt dates)
• Expense invoices (faturalar)
• Bağ-Kur payment confirmations
• Serbest meslek defteri (professional ledger)
• Tax return filing confirmations
• Prop firm contracts

Common Mistakes to Avoid

1. Not Converting at TCMB Rates

Foreign currency income must be converted at the TCMB exchange rate on the date of receipt, not the date of the tax return or an averaged rate.

2. Not Registering as Serbest Meslek

Freelance/professional registration requires a notarized serbest meslek defteri and registration at the vergi dairesi. Operating without registration creates compliance issues.

3. Missing Quarterly Geçici Vergi

Quarterly provisional tax declarations are mandatory. Non-filing triggers penalties and interest.

4. Declaring Bağ-Kur at Actual Income

Most self-employed declare at the minimum base. Declaring at actual (higher) income increases social contributions significantly without proportional benefit increases.

5. Not Claiming Hizmet İhracatı KDV Exemption

Services to foreign entities are KDV-exempt. Not claiming the exemption means unnecessarily applying 20% KDV.

6. Assuming Capital Gains Treatment

Prop firm payouts are not capital gains. Freelance/professional or commercial income classification applies.

Tax Planning Strategies

Declare Bağ-Kur at Minimum Base

Minimize social security costs by declaring at the minimum wage base. The pension benefit difference between minimum and higher bases is modest relative to the contribution cost.

Leverage Currency Depreciation

If the TRY depreciates, the same USD income may fall into lower TRY tax brackets. While not a controllable strategy, it's an important modeling consideration.

Consider a Şirket (Company) Structure

Turkey's corporate tax rate is 25% (increased from 20% in 2023). For high-income traders, a limited company (limited şirket) with optimized salary/dividend extraction may be more efficient than individual taxation at 35–40% marginal rates.

Maximize Deductions

At marginal rates of 27–40%, every lira of legitimate deduction provides meaningful tax savings.

Professional Advice (Mali Müşavir)

Engage a Turkish mali müşavir (certified public accountant). Monthly fees: TRY 2,000–5,000, fully deductible. Essential for quarterly geçici vergi filings and annual return preparation.

Evaluate Living in Lower-Cost Turkish Cities

Turkey's tax rates are uniform nationwide, but living costs vary dramatically. Istanbul is expensive; cities like Antalya, İzmir, or Ankara offer lower living costs while maintaining good infrastructure.
