What is Gecici Vergi?

Gecici Vergi (provisional/advance tax) is Turkey's mechanism for spreading the collection of income and corporate tax throughout the year rather than collecting it in a lump sum at year end. It is governed by Gelir Vergisi Kanunu Article 120 (for individuals) and Kurumlar Vergisi Kanunu Article 32 (for companies).\n\n**Who pays**\nAll commercial businesses (those with Ticari Kazanc) and self-employed professionals (Serbest Meslek Kazanci) must pay Gecici Vergi quarterly. Agricultural businesses, employment income recipients, and rental property investors do not pay Gecici Vergi — their tax is collected via withholding or annual declaration only.\n\n**Calculation basis**\nFor corporate taxpayers (KV payers): quarterly commercial profit is calculated on an accrual basis using the same accounting records as the annual Kurumlar Vergisi. The tax rate is 25% (for 2025). Cumulative profit year-to-date less prior quarter's cumulative figure gives the quarter's increment, multiplied by 25%, less prior quarters' payments.\n\nFor individual commercial/professional taxpayers: the quarterly commercial profit is the relevant quarter's accrual-basis net income from commercial or professional activities. The applicable Gelir Vergisi bracket rate for that accumulated income is used.\n\n**Quarterly filing deadlines**\n- Q1 (January-March): declaration due 17 May, payment due 17 May\n- Q2 (April-June): declaration due 17 August, payment due 17 August\n- Q3 (July-September): declaration due 17 November, payment due 17 November\n- Q4 (October-December): declaration due 17 February of the following year, payment due 17 February\n\nFilings are made via the GIB e-Beyanname portal. Gecici Vergi is one of the most common declarations filed by Turkish businesses.\n\n**Credit against annual tax**\nAll four quarterly Gecici Vergi payments are credited against the final annual Kurumlar Vergisi or Gelir Vergisi liability declared in the annual return. If the cumulative quarterly payments exceed the annual liability, the excess is refunded or offset against other tax debts. Overpayments are interest-free if the refund is obtained within one year.\n\n**Penalties for late filing or underpayment**\nLate filing: Ozel Usulsuzluk Cezasi (irregularity fine) of 1% of the quarterly tax base (minimum TRY 4,400 for 2025). Underpayment by more than 10% versus actual quarterly profit: additional tax plus interest at the current Gecikme Faizi rate. The Revenue Administration can initiate a Gecici Vergi Tarh Takdir (audit estimation) if filed returns appear unreasonably low compared to turnover.
