If you provide services such as software development, data analysis, artificial intelligence solutions, engineering, or design to clients abroad from Turkey, understanding how your income is taxed is critically important.
Under Article 89 of the Turkish Income Tax Law, certain service exports allow taxpayers to deduct 80% of their earnings from the taxable income base, provided specific conditions are met.
This regulation creates a significant tax advantage especially for freelancers, remote professionals, software developers, and technology-focused entrepreneurs earning foreign currency.
What Does the 80% Income Deduction Mean?
According to the regulation:
- The service must be provided to a non-resident individual or company.
- The benefit of the service must be realized abroad.
- The service must fall within specific sectors defined by law.
Under these conditions, 80% of the net income generated from the service can be deducted from the taxable income.
Important note: The deduction is applied to the net profit after expenses are deducted, not to the gross revenue.
Who Can Benefit From This Tax Advantage?
To qualify for the deduction, the following conditions must be met simultaneously:
1. The Client Must Be Located Abroad
The service must be provided to:
- An individual who is not resident in Turkey, or
- A company whose legal headquarters and management center are located outside Turkey.
Services provided to companies operating within Turkey do not qualify for this incentive.
2. The Service Must Be Utilized Abroad
The service may be produced in Turkey, but the economic benefit must occur outside Turkey.
For example:
- Developing software for a U.S.-based SaaS company qualifies.
- Engineering services used in a project located in Turkey do not qualify.
This distinction is one of the most common sources of errors in practice.
3. The Activity Must Fall Within Eligible Service Categories
The law does not cover every type of service. The main eligible sectors include:
- Software development
- Data processing and analytics
- Artificial intelligence solutions
- Engineering and design services
- Architecture services
- Accounting record services
- Call center services
- Product testing and certification
If the service provided does not fall within these categories, the deduction cannot be applied.
4. The Invoice Must Be Issued Correctly
The invoice must be issued directly to the foreign client receiving the service.
Issuing invoices to intermediary payment platforms may create risks and could invalidate the deduction.
5. The Income Must Be Transferred to Turkey
The revenue generated from the service must be transferred to Turkey before the income tax return is submitted for that year.
Incomplete payments or delayed transfers may result in rejection of the deduction.
Can Freelancers Using Online Platforms Benefit?
Yes, it is possible.
However, the following conditions must be carefully evaluated:
- The final client must be located abroad.
- The invoice must be issued to the correct party.
- The service contract and description must be clear.
If the platform only acts as a payment intermediary and the export conditions are met, the tax deduction can generally be applied.
Example Tax Calculation
- Annual Revenue: 1,200,000 TL
- Total Expenses: 300,000 TL
- Net Profit: 900,000 TL
- 80% Deduction: 720,000 TL
- Taxable Income: 180,000 TL
In this scenario, the effective income tax rate can drop significantly, often falling within approximately 6%–9%, depending on the income bracket.
Is It Mandatory to Establish a Company?
Yes. Since this income is generated through continuous commercial activity, a formal tax registration is required.
The most common structure used in practice is:
- Sole proprietorship
This structure is popular because:
- It has lower setup costs
- Accounting procedures are simpler
- It works well with the 80% deduction mechanism
However, depending on income levels, establishing a limited company may also be considered.
Common Mistakes in Practice
- Operating under an incorrect NACE activity code
- Writing insufficient service descriptions on invoices
- Using incorrect terminology in contracts
- Declaring income incorrectly
- Failing to transfer revenue to Turkey on time
These mistakes may lead to the deduction being rejected entirely and could result in retroactive tax assessments and penalties.
What Should Be Included in Service Contracts?
The service contract should clearly specify:
- The nature of the service provided
- That the benefit of the service is realized abroad
- The residency status of both parties
Ambiguous wording may cause complications during potential tax audits.
Frequently Asked Questions
Do I have to convert my foreign currency income into Turkish Lira?
No. There is no obligation to convert foreign currency into Turkish Lira for service export revenues.
I receive payments through global payroll platforms. Is this a problem?
Generally no, as long as the invoice is issued to the correct client. However, the structure should still be carefully reviewed.
Can I receive payments in cryptocurrency?
Since cryptocurrency is not officially recognized as a payment method under current regulations, receiving payments in crypto may create risks for applying this deduction.
Conclusion
The 80% income deduction for software and digital services exported abroad offers a substantial tax advantage when applied correctly. However, all legal requirements must be carefully fulfilled.
An incorrectly structured model can lead to significant tax liabilities and penalties. Therefore, freelancers and technology professionals working remotely should ensure proper tax planning before starting their activities.
