# Service Used Abroad Test in Turkey: What Remote Workers Must Prove

**Canonical URL:** `https://evrenozmen.com.tr/service-used-abroad-test-turkey`

**Last reviewed:** 18 August 2026

## Direct Answer

For Turkish service export tax benefits, a foreign client is not enough. The service must be used or benefited from abroad. If the work supports Turkish operations, Turkish customers, a Turkish subsidiary or a Turkish market, the service-used-abroad condition may fail and both income tax deduction and VAT exemption can be at risk.

## Clean vs Risky Cases

| Case | Risk level |
|---|---|
| Backend software for foreign SaaS used outside Turkey | Lower |
| Design for a foreign brand's Turkish campaign | Higher |
| Data analysis for a UK research project | Lower |
| Consulting for a foreign company's Turkish subsidiary | Higher |
| Engineering drawings for an overseas construction project | Lower |

## Evidence to Keep

- Contract scope
- Invoice wording
- Project documentation
- Client confirmation of use abroad
- Delivery records
- Emails showing business purpose
