Short Answer
Consulting for foreign clients from Turkey is not automatically covered by the 100% service export deduction. Some consulting may fit listed categories such as engineering, design, data analysis or software-related services, but general business, marketing or market-entry consulting needs careful classification. VAT and Turkish-use risk should be reviewed before invoicing.
Short Summary
Foreign-client consulting income in Turkey depends on tax residence, business registration, service classification, client location, use abroad, invoice model and payment route. The 100% service export deduction is safest when the consulting falls within a listed eligible service and the foreign-use condition can be proven.
Consulting Classification
| Consulting type | Typical risk |
|---|---|
| Software implementation consulting | May be eligible if documented |
| Engineering consulting | May be eligible if used abroad |
| Data analytics consulting | May be eligible if output used abroad |
| Turkey market-entry consulting | High Turkish-use risk |
| General business advisory | Needs classification review |
