Quick answer
How companies in Turkey should manage VAT, withholding, payroll, provisional and annual corporate tax deadlines using the current official tax calendar.
A Turkey tax filing calendar must be built for the company’s actual registrations, transactions and workforce. VAT, withholding, payroll, provisional tax and annual corporate tax do not apply in the same way to every entity, and statutory dates can change through legislation or administrative announcements. Use the current official calendar, not a copied annual checklist.
Core Compliance Cycles
| Cycle | Typical workstream | What determines applicability |
|---|---|---|
| Monthly | VAT, withholding, payroll and social security | Transactions, payments and employees |
| Quarterly | Provisional corporate tax and management review | Taxpayer status and current rules |
| Annual | Corporate tax return, closing and statutory books | Fiscal year and entity status |
| Event-driven | Stamp tax, registry changes, share transfers and special notices | Contract or corporate event |
| Sector-specific | Banking, regulated activity, incentives or special levies | Licence, sector and investment status |
The Revenue Administration’s table of filing and payment periods (checked October 2026) gives these typical statutory dates for a company on the standard calendar:
| Return | Typical statutory date |
|---|---|
| VAT return and payment | 28th of the month following the tax period |
| Withholding and social security premium return (monthly filers) | 26th of the following month |
| Withholding and social security premium return (quarterly filers) | 26 April, 26 July, 26 October and 26 January |
| Provisional corporate tax | 17th of the second month after each quarter: 17 May, 17 August, 17 November and 17 February (fourth provisional period from 2025, Law 7566) |
| Annual corporate tax return and payment | From the first day to the last day of the fourth month after the accounting period closes, so 1 to 30 April for a calendar-year company |
Payment is due within the filing period. Dates can move with official extensions or holidays and depend on the company’s registrations, so always verify filing and payment dates in the GİB Tax Calendar. Official extensions and force-majeure announcements may alter a date for a period or taxpayer group.
Build Two Calendars, Not One
The statutory calendar states the external deadline. The internal close calendar should be earlier and assign who supplies invoices, bank statements, payroll data, contracts and approvals. A practical sequence is document cut-off, reconciliation, technical review, management approval, filing and payment confirmation.
Use the monthly accounting requirements checklist to define inputs. Companies with foreign parents should add group-reporting deadlines and related-party review without confusing these with Turkish statutory filings.
Common Calendar Failures
- Assuming a dormant or low-volume company has no filings.
- Treating filing and payment as the same operational step.
- Sending payroll changes after the internal cut-off.
- Reviewing contracts only after payment, when withholding or stamp tax has already arisen.
- Using an old blog’s date instead of the current official calendar.
- Ignoring event-driven obligations after a capital, address, manager or shareholder change.

Frequently Asked Questions
Are Turkish tax deadlines the same every year?
Do not assume so. Rules, extensions and administrative announcements may change a deadline. Confirm the relevant period in the official Revenue Administration calendar.
Does every Turkish company file VAT monthly?
Not necessarily. Applicability depends on tax registration, activities, transactions and any special status. The company’s registration and current rules must be reviewed.
What is the difference between a filing date and payment date?
They are separate compliance controls even when close together. The company should track return preparation, approval, submission, assessment or accrual, and payment confirmation.
What should a foreign parent add to the calendar?
Add group reporting, consolidation, intercompany reconciliation, transfer-pricing evidence and cash-remittance decisions, while keeping those internal dates separate from Turkish statutory deadlines.
Who is responsible for the tax calendar?
Management remains responsible for compliance, while the accounting or tax adviser manages agreed preparation and filing tasks. A written responsibility matrix prevents gaps.
