Service based on personal labour
Where you provide the service through your own labour, it is professional income: a professional earnings ledger is kept and a professional receipt issued.
Foreign income
If you provide software, design or consultancy services to a client abroad, the income is taxable in Türkiye — but the law contains reliefs that substantially reduce it. Structured badly, none of them can be used.
Basics
Where you provide the service through your own labour, it is professional income: a professional earnings ledger is kept and a professional receipt issued.
Where a team, capital and organisation dominate, the activity is commercial income: operating or balance-sheet books apply and invoices are issued.
If the activity runs through a company, corporate tax applies and reliefs are applied to corporate income.
The main relief
The 80% deduction applied to services such as architecture, engineering, design, software, medical reporting, bookkeeping, call centres, product testing, data storage and processing, education and health was raised to 100% on condition that the entire income is brought into Türkiye.
Value added tax
A service provided to a client abroad and used abroad is exempt from VAT. The invoice is issued without VAT. Input VAT incurred on these transactions may be reclaimed, which requires its own documentation.
| Item | Treatment |
|---|---|
| Invoice | No VAT charged; the exemption is noted |
| Return | Shown on the exemption line of the VAT return |
| Input VAT | Recovered by refund or deduction |
| Documents | Contract, invoice and bank records showing the payment came from abroad |
Starting out
Those registering as taxpayers for the first time and meeting the age condition are exempt from income tax on a set amount of earnings for three tax periods. The amount is increased annually by the revaluation rate. Conditions include personally running the business and registering for the first time.
Practice
Amounts arriving through payment intermediaries must be traceable to an invoice. Mixed collections put both the deduction and the VAT exemption at risk.
The difference between invoice date and collection date is recorded as income or expense, using the Central Bank rate on the collection date.
The nature of the service, where it is used and the fee must be explicit. This is the first document requested on an audit.
Platform commission is an expense and the gross amount is revenue. Recording the net receipt as revenue is a common and costly error.
Yes. If you are registered, you must issue a professional receipt or invoice for the fee. It may be made out to the foreign client in foreign currency; the entry is made at the rate on the collection date.
No. The VAT exemption means no VAT is charged on the service. The earnings deduction reduces the income or corporate tax base. Their conditions and documents differ; one may apply without the other.
It depends on income level, expense structure, whether there are partners and your dividend plans. At a small, single-person scale individual registration is usually lighter; as income grows and partners join, a company comes forward. Do not decide without running the numbers.
The highest deduction rate depends on bringing the entire income into Türkiye. Otherwise a lower rate applies. Obligations on declaring foreign accounts and assets should also be reviewed.
