Türkiye tax and compliance calendar: your next deadlines
VAT, withholding, stamp tax, social security, Ba/Bs, e-Ledger, provisional and annual corporate tax deadlines, with the next dates counted from today.
The recurring tax and social security deadlines a Turkish company works to, with the next dates calculated from today. Dates are the statutory days. When a deadline falls on a weekend or public holiday it moves to the next working day, and the Revenue Administration (GİB) sometimes extends deadlines by circular, so confirm on gib.gov.tr before you plan on the last day.
