# German Software Developer Working Remotely from Turkey: Tax Guide 2027

**Last reviewed:** 19 August 2026

**Author:** Evren Özmen, CPA / SMMM

## Short Answer

A German software developer working from Turkey can have very different Turkish tax outcomes depending on whether the income is German salary, independent contractor income, Turkish sole proprietorship income or Turkish company income. If the developer invoices a German or other foreign client for software services used abroad, Turkey's 100% service export deduction may be reviewed. German tax residence, treaty position and exit facts must be checked separately.

## Short Summary

For a German software developer in Turkey, the first tax question is not the client country but the work model. German payroll, contractor agreements, Turkish sole proprietorship invoices and Turkish company invoices each create different Turkish tax, VAT, social security and treaty questions. Software development can fall within the Turkish service export deduction rules if all conditions are met.

## Decision Table

| Work model | Main Turkish review |
| --- | --- |
| German payroll employee in Turkey | Salary taxation, treaty, payroll and social security |
| Contractor paid by German company | Turkish registration, invoice, VAT and 89/13 |
| Turkish sole proprietorship invoices Germany | GVK 89/13 and service export documentation |
| Turkish limited company invoices Germany | KVK 10/1-g and corporate accounting |
| German GmbH owner works from Turkey | Management, permanent establishment and personal tax residence |

## Software Export Focus

Software development is one of the service categories that may be reviewed under Turkey's service export deduction rules. The key practical question is whether the software service is used abroad. If the project supports Turkish operations, Turkish users or a Turkish subsidiary, the benefit may be at risk.

## FAQ

### Does a German client make the income foreign-source?

Not automatically. If the person performs active work while living in Turkey, Turkish tax residence and source rules still need review.

### Can German software developers use 89/13?

Possibly, if they invoice as a business or professional, the service is eligible software work, the client is abroad, the service is used abroad and the transfer and documentation conditions are met.

### Is 20/D the right regime?

Usually not for active work performed from Turkey. Article 20/D belongs to foreign passive income and specific Non-Dom facts.
