When Annual Affiliate Income Triggers Esnaf Vergisi Exit in Turkey

Aylin from Izmir ran a thMenu affiliate funnel at 30,000 TRY MRR through 2025. Her tax advisor delivered the bad news in December: she'd quietly exited the Turkish esnaf vergisi (artisan tax exemption) six months earlier, and the back-tax plus penalty came to 18,000 TRY. Knowing the 2026 ceiling — 330,000 TRY annual gross — protects every affiliate operating from Turkey.

The 2026 Esnaf Ceiling and Monthly Trigger

Under Income Tax Law (GVK) article 9, the small-trader exemption is preserved only if your annual gross revenue stays below 330,000 TRY for 2026, indexed via the official revaluation rate. Divided across twelve months, that's a 27,500 TRY monthly average ceiling. Once exceeded, you enter the "income-earning trader" category and must register.

Note that gross means pre-fee revenue, not net payout. A 30,000 TRY net wire from thMenu corresponds to roughly 31,500 TRY gross after Stripe and platform fees back out. Annualized that's 378,000 TRY — clearly past the line.

The Izmir Case: How 18,000 TRY Materialized

Aylin's 2025 gross hit 360,000 TRY by year-end. She crossed the threshold around May but didn't register until April 2026. The breakdown her advisor produced:

• Net taxable income after 75,000 TRY deductions: 285,000 TRY
• Income tax bracket (15-27%): 14,200 TRY
• Stamp duty + BAĞ-KUR + late penalty: 3,800 TRY → 18,000 TRY total

A timely May notification within 30 days would have eliminated the 2,500 TRY late penalty and lowered her effective bill to 15,500 TRY.

Basit Usul vs Şahıs Şirketi vs Ltd. Şti

For annual affiliate income between 330,000 and 880,000 TRY, basit usul (simplified bookkeeping) is the sweet spot: net effective tax 10-15%, no formal ledger, accountant fees of 6,000-9,000 TRY annually. Beyond 880,000 TRY a balance-sheet sole proprietorship (şahıs şirketi) becomes mandatory.

The Ltd. Şti structure only pencils out above roughly 2 million TRY — corporate tax 25% plus dividend withholding lands you at ~33% effective. For most mid-tier affiliates, the sole proprietorship wins every time on simplicity and tax burden.

FAQ

I crossed 27,500 TRY in one month — do I file immediately? Not yet. The 330,000 TRY annual ceiling is what triggers mandatory exit. But if you exceeded by 50%+ in Q1, project your annual run-rate and consider filing in Q2 to avoid year-end penalty exposure.

My affiliate payout is in USD/EUR — what FX rate do I use? Use the TCMB (Turkish Central Bank) effective sell rate on the date the commission was paid. The 330,000 TRY threshold is checked against your cumulative TL-converted gross.

Payout date vs accrual date — which counts for tax? Tax authority follows the accrual date (when the Stripe webhook records your commission), not when you actually withdraw it. Your monthly dashboard "commission accrued" report should be the basis of your tax filing.
