Turkey’s New Digital Platform Reporting Rules: What Foreign Platforms Need to Know
Turkey has expanded and restructured its information-reporting framework for online marketplaces, listing platforms, hosting providers and social networks. Foreign digital businesses serving the Turkish market should now determine whether their platform falls within the reporting framework, what user data must be collected and whether monthly BTRANS reporting is required.
Executive Summary
- Turkey published Tax Procedure Law General Communiqué No. 595 on 5 September 2026, amending Communiqué No. 538.
- The regulatory language now expressly addresses a broader digital ecosystem, including e-commerce providers, intermediary service providers, access providers, content providers, hosting providers and social network providers.
- Specific monthly information-reporting requirements continue to apply to qualifying intermediary service providers, while a separate reporting rule now addresses hosting providers and social network providers that enable relevant listings.
- Reportable information can include platform URLs, seller or advertiser identification information and information relating to sales, rentals and online listings.
- Reporting under Communiqué No. 538 is made electronically through the Turkish Revenue Administration’s BTRANS system and is generally organised on a monthly basis.
- A foreign platform should not assume that it is outside the regime simply because it has no Turkish subsidiary. Equally, having Turkish users does not by itself establish that every foreign platform is automatically subject to the reporting obligation.
For international digital businesses, the important development is not simply that Turkey is collecting more information. The more significant point is that the Turkish tax administration is extending its visibility beyond conventional e-commerce transactions into a wider range of digital listings, commercial interactions and platform-based activity.
This matters for marketplaces, classified advertising businesses, property and vehicle platforms, social networks, service marketplaces and other digital businesses with a Turkish user base.
1. What changed on 5 September 2026?
On 5 September 2026, Turkey published Tax Procedure Law General Communiqué No. 595 in Official Gazette No. 33361.
The Communiqué amends the existing information-reporting framework established under Tax Procedure Law General Communiqué No. 538.
The underlying policy objective is tax transparency: enabling the Turkish Revenue Administration — the Gelir İdaresi Başkanlığı, or GİB — to identify and reconcile economic activity taking place through digital channels.
The amended wording goes beyond a narrow concept of e-commerce and expressly refers to the use of the internet and other digital environments for economic and commercial purposes including:
- buying and selling;
- rentals;
- online listings;
- advertising; and
- other digital commercial activity.
The enabling language also refers to several categories within the digital ecosystem, including service providers, electronic commerce service providers, intermediary service providers, electronic commerce intermediary service providers, access providers, content providers, hosting providers and social network providers.
The fact that a category appears in the broader statutory authority does not necessarily mean that every business falling within that description has identical monthly reporting requirements. The operative provisions need to be analysed according to the platform’s actual legal and technical role.
2. Which foreign platforms should review the rules?
Any international platform facilitating commercially relevant activity involving Turkey should consider whether the amendment affects its reporting architecture. The review is particularly relevant for businesses operating models such as:
The correct analysis is based on function, not branding.
A company describing itself as a technology company, SaaS provider or advertising platform may still perform a role that Turkish legislation classifies as an intermediary service provider, hosting provider or social network provider.
Conversely, a business should not be treated as subject to the monthly reporting requirement merely because Turkish users can access its website.
3. Do the rules apply to foreign digital platforms?
This is likely to be the first question for a multinational tax or legal team.
The analysis should begin by mapping the platform against the definitions used under Turkish electronic commerce and internet legislation, including the Electronic Commerce Law No. 6563 and Internet Law No. 5651.
Relevant factual questions include:
- Does the platform enable third parties to conduct commercial activity?
- Does it publish or host listings for goods, services or rentals?
- Can Turkish users create commercial content or advertisements?
- Does the platform process or facilitate transactions?
- Does it collect seller, advertiser or property-owner identification data?
- Does it process payments or receive transaction information?
- Does it operate a Turkish website, app, domain, local interface or local entity?
- How is the service legally classified under Turkish digital regulation?
These questions should be answered before determining the reporting position.
A Turkish subsidiary is not the only relevant factor
International groups often start their analysis with a corporate structure chart: “We have no company in Turkey, therefore there is no Turkish compliance obligation.”
That approach can be too narrow for digital regulation.
Turkey already applies several tax and regulatory rules to non-resident digital businesses without requiring them first to incorporate a conventional Turkish subsidiary. Platform reporting therefore needs to be analysed separately from questions such as corporate income tax presence, permanent establishment, digital services tax or VAT registration.
4. What information may need to be reported?
The required dataset depends on the role of the platform.
Following the September 2026 amendment, the information contemplated under the reporting framework includes items such as:
| Data category | Examples | Practical impact |
|---|---|---|
| Platform information | Internet address or addresses through which the service is provided | Mapping Turkish-facing digital channels and reporting entities |
| User identification | Name, surname or legal entity name | User onboarding and master-data requirements may need review |
| Taxpayer identification | TCKN, YKN, VKN or similar information relevant to taxpayer identification | Platforms may need additional Turkish-specific data fields |
| Listing information | Information relating to goods, services, movable assets, real estate, sales or rentals advertised through the platform | Listing databases may need to be mapped into the Turkish reporting format |
| Transaction information | For relevant intermediary models, transaction or payment-related information may also fall within the existing reporting framework | Tax, payments and platform engineering teams may need to coordinate data extraction |
The distinction between intermediary platforms and hosting/social networks matters
Communiqué No. 595 restructures Article 4 of the existing Communiqué.
Qualifying intermediary service providers remain within a reporting framework that can include transaction-level information.
A separate paragraph now addresses hosting providers and social network providers that enable the publication of listings relating to the purchase, sale or rental of movable assets, immovable property, goods or services.
For this category, the specified information includes the relevant internet address, identification information of the person or entity receiving the service and information relating to the listing.
5. How does monthly reporting work?
The reporting infrastructure under Communiqué No. 538 uses the GİB Information Transfer System (BTRANS).
Under the existing framework, reportable information is submitted monthly. Information relating to a calendar month is generally required to be transmitted by 23:59 on the last day of the following month.
Data format and technical standards are communicated by the Turkish Revenue Administration through BTRANS.
Communiqué No. 595 entered into force on its publication date, 5 September 2026.
Businesses that may become affected by the amended provisions should therefore confirm their first reportable period, BTRANS position and data readiness rather than assume that a separate grace period applies.
This is not only a tax-team project
For a large digital business, compliance can require input from several teams:
- Tax;
- Legal;
- Regulatory compliance;
- Data privacy;
- Payments;
- Product;
- Engineering; and
- Seller or user onboarding.
If the platform currently does not collect Turkish taxpayer-identification information, the issue may require a product or onboarding change rather than simply preparation of another tax return.
6. Is this a new tax on digital platforms?
No.
Communiqué No. 595 is principally an information-reporting and tax-transparency measure.
It should therefore be distinguished from Turkey’s other tax rules affecting international digital businesses, including VAT, Digital Services Tax, withholding tax and corporate income tax or permanent-establishment issues.
That does not make the reporting obligation insignificant.
Platform-level data can give the Turkish Revenue Administration greater ability to reconcile sellers, advertisers, landlords, service providers, listings and transactions against existing Turkish taxpayer records and declarations.
For a multinational platform, the compliance question is therefore both regulatory and operational.
7. What should foreign digital platforms do now?
We recommend a structured applicability review rather than immediately building a reporting solution.
Do not start with the question “Do we need to file a report?” Start with “How is each element of our platform legally classified in Turkey?” Once that classification is clear, the reporting and data requirements can be mapped correctly.
8. Frequently Asked Questions
Does Turkey’s new platform reporting rule apply to every foreign website with Turkish users?
No. Turkish users alone should not be treated as sufficient to conclude that every foreign website is automatically subject to monthly reporting. The platform’s functions, legal classification and Turkish-facing activities should be reviewed against the relevant Turkish legislation.
Does a foreign platform need a Turkish company before the reporting rules can apply?
The absence of a Turkish subsidiary should not be used as the sole basis for concluding that the rules are irrelevant. Non-resident digital businesses should separately assess whether their activities fall within the Turkish platform-reporting framework.
Is this a new tax on marketplaces or social networks?
No. Communiqué No. 595 primarily concerns information reporting and tax transparency. VAT, Digital Services Tax, corporate income tax and other Turkish tax obligations are separate issues.
Are the reports filed monthly?
The reporting framework under Communiqué No. 538 operates on a monthly basis. Reportable information for a month is generally submitted through BTRANS by the end of the following month.
What is BTRANS?
BTRANS is the Turkish Revenue Administration’s Information Transfer System used for the electronic submission of specified datasets. The Revenue Administration communicates relevant data formats and technical standards through the system.
What information can platforms be required to report?
Depending on the platform category, information can include the relevant internet address, user or business identification details, Turkish taxpayer identification information, listing information and, for certain intermediary models, transaction-related data.
Does outsourcing payment processing remove the reporting obligation?
Not necessarily. Under the existing reporting framework for relevant intermediary service providers, using a bank or payment institution for payment processing does not by itself eliminate the information-reporting analysis.
What should a foreign platform do first?
The first step should be an applicability and platform-classification review. The business can then determine the required data fields, reporting entity, BTRANS requirements and any implementation gaps.
Does Turkey’s new platform reporting regime apply to your business?
