Business Support in the UAE and Abroad
February
Q4 advance
Starting with returns for 2025, the corporate income tax advance is once again filed for Q4 too — in the second month after the quarter, as for Q1–Q3.
Minimum corporate tax — not in the first three years
Since 2025, corporate income tax cannot be less than 10% of profit before reliefs and deductions. New companies are exempt from this rule for three tax periods, counting the year they start operating; companies created by merger, division or conversion are not.

Ongoing Support for a Company in Turkey: Bookkeeping, Taxes and Reporting
After registration, a Turkish company reports every month — even with no revenue: VAT, corporate income tax advances, e-invoices, the annual general meeting, the foreign investment report. We keep the books with Turkish accountants, hold the deadlines and carry out changes to the company — from a share transfer to closure.
- by the 28th
- VAT for the previous month — even in months with no sales
- TRY 8,000–16,000
- Online bookkeeping per month excluding VAT, indicative as of 5 October 2026
- TRY 35,000
- Fine per late return in 2026
- by 31 May
- Annual E-TUYS form for a foreign-capital company
In short
A Turkish company reports every month, even with no revenue: VAT for the previous month by the 28th, the annual E-TUYS form by 31 May, and each late return in 2026 means a TRY 35,000 fine. Online bookkeeping costs TRY 8,000–16,000 a month excluding VAT, indicative as of 5 October 2026; our fee is separate.

Cost of a mistake
End of day five
That is when a notice in the tax office’s electronic box is deemed served, and the deadlines for payment and appeal run even if it was never opened.
How to avoid itWhat a Turkish company does after registration
A company in Turkey runs on the tax calendar: returns every month, invoices in electronic form only, tax office notices in an electronic box. A missed deadline costs more than an accountant.
Reporting every month
VAT for the previous month — by the 28th, even with zero sales. If there were salaries or payments subject to withholding tax — also a combined return by the 26th.
Four advance payments a year
Starting with returns for 2025, the corporate income tax advance is once again filed for Q4 as well. The annual return is due by 30 April; the rate is 25%.
Invoices — electronic only
From 2026, a company issues all its invoices electronically: e-Fatura or e-Arşiv. With turnover of TRY 3 million or more, e-Fatura is mandatory.
Tax notices go to an e-box
Companies are required to use the tax office’s electronic notification system. A notice is deemed served at the end of the fifth day — even if nobody opened it.
Expert tip
If another accountant kept the books, we start with a reconciliation: what has been filed, what has been paid and what is sitting in the tax office’s electronic box. This shows the real debts before late-payment interest builds up.

What clients come to us with
Typical situations
- 01The company has just been registered, and bookkeeping is needed from the first month.
- 02The company exists, but there is no revenue yet — and it’s unclear what to file.
- 03The accountant has left or isn’t responding, and return deadlines keep running.
- 04You need to add or remove a participant, or change the manager or the address.
- 05The owners live abroad and need a single contact for bookkeeping, taxes and the registry.
- 06The company is no longer needed and has to be closed with no debts left behind.
Similar, but different
- 01There is no company in Turkey yet — first comes the form, the regime and registration.Turkey
- 02You only need an account with a Turkish bank for a company from another country.Turkey
- 03You need a residence permit or a work permit — company bookkeeping does not give these; we assess the requirements separately.
Company calendar
The first six months: almost all of the annual reporting falls here
For a Ltd. Şti. or A.Ş. whose financial year matches the calendar year. A deadline that falls on a non-working day moves to the next working day. Monthly filings, annual fees and event-driven deadlines are below the scale.
0123456months after 31 December
March
Annual general meeting
By 31 March — approve the financial statements and the annual report for the previous year and decide what to do with the profit. With a sole participant — a written resolution.
April
Corporate income tax for the year
Return and payment — by 30 April, even with a loss: a loss can be carried forward to future years only from filed returns.
If missed: TRY 35,000 for a late return (2026) and 3.7% a month on unpaid tax
May
Foreign investment report
By 31 May — the annual activity form in E-TUYS.
June
Chamber fees
The first half of the annual and additional chamber fees. The additional fee is 0.5% of profit per the annual return and is not payable in a loss-making year.
Every month and quarter
By the 28th of the following month
VAT
The return for the previous month is filed even in months with no sales; any tax due is paid by the same date.
If missed: TRY 35,000 for a late return (2026)
By the 26th of the following month
Withheld taxes and social security
The combined return and withheld tax — if there were salaries or payments subject to withholding; the SGK contributions themselves — by the end of the following month.
February, May, August, November
Corporate income tax advance
For each quarter; advances paid are credited against the annual tax.
Every year
October
Second instalment of chamber fees
The annual fee and 0.5% of the profit per the return — the second equal instalment. In the year of joining the chamber, an entrance fee is paid instead of the annual one.
By 31 December
Paper books for the new year
The notary certifies the inventory book if it is kept on paper and, for an A.Ş., a paper board resolutions book. The journal and general ledger are in e-Defter and need no notary; the share book and the meetings book are not renewed while they have pages left.
By 31 January
Closing the board resolutions book
If an A.Ş. keeps its board resolutions book on paper, the notary closes it for the previous year; an electronic book doesn’t need this.
Event-driven
Annual turnover of TRY 3 million or more
Switch to e-Fatura
From 1 July of the following year — e-Fatura. The company already has e-ledgers: they have been mandatory since 2025.
30 days after a share transfer
New participant — to the registry
The managers file a share transfer in a Ltd. Şti.; if they don’t, the departing participant may ask the registry to remove their name.
A month after a change
E-TUYS, beneficial owners and the tax office
Share transfers — to E-TUYS; new beneficial owners and a new address — to the tax office.
Before work starts
Employee — to SGK
A new employee is reported to SGK before they start work, not after.
On a capital increase
0.04% contribution
To the Competition Authority — on the amount of the increase, before the registry entry.

New participant or closure: who does what
Two common situations after registration. Decisions and signatures come from you; the registry, notifications and the tax office are on us.
From you — the buyer’s details and signatures at the notary; the registry, E-TUYS and beneficial owners — on us. Company tax debts from before the sale that could not be collected from the company itself are covered jointly by the seller and the buyer — up to their share.
From you — the participants’ resolution; the notices, the tax office and the registry are on us. Assets are not distributed earlier than three months after the third notice, unless a court permits otherwise.
Let’s discuss the details
Is your company sitting idle with no revenue?
We’ll work out what it costs to keep for a year — bookkeeping, address, chamber — and compare that with closing it: which makes more sense in your case.
