The E-audit system in Turkey marks a major step forward in the digitalization of tax inspections and compliance processes. The Tax Inspection Board (VDK) officially launched the E-Audit System (e-İnceleme Sistemi) on July 1, 2025. With this system, businesses can now submit documents electronically and complete audit procedures securely through digital platforms.
The goal of the E-Audit System is to increase efficiency and transparency in tax audits while reducing time and cost — especially for companies operating in multiple locations across Turkey.
What is the E-Audit System in Turkey?
The E-Audit System in Turkey is an integrated digital platform that enables taxpayers to submit their e-books, financial documents, and other required files digitally to tax inspectors, and to sign official audit reports (tutanak) electronically.
All communication and documentation during a tax audit can now be managed remotely — eliminating the need for physical delivery, in-person meetings, or wet signatures.
Key Benefits of the E-Audit System for Businesses in Turkey
The E-Audit System provides several significant advantages for companies operating in Turkey:
- ✅ Secure digital submission of e-books, invoices, and other audit-related files
- ✅ Electronic signing of audit reports using legally recognized digital signatures
- ✅ Remote management of the entire tax inspection process
- ✅ Time and cost savings through digital workflows
- ✅ Increased audit transparency and traceability
- ✅ More efficient use of public resources and faster resolutions
This system is particularly valuable for medium and large-scale enterprises with multiple branch locations or companies that maintain digital accounting systems.
Who Can Use the E-Audit System in Turkey?
To access the system, companies must meet the following four conditions simultaneously:
- There must be an ongoing tax audit concerning the taxpayer.
- An official “Audit Commencement Notification” must have been delivered.
- Authorized persons must be defined in the Authorization Identification System.
- Those authorized must possess a qualified electronic signature in compliance with Law No. 5070 in Turkey.
Once these conditions are met, companies can use the e-Audit System without any separate application.
How to Access the System?
Taxpayers can log in to the system using the “Inquiry Number (Sorgu No)” provided in the official Audit Commencement Notification. This number is unique to each inspection and must be used throughout the digital document submission and report-signing process.
Integration with e-Viz: A Stronger Audit Infrastructure
The e-Viz System, which was launched in 2023 for signing audit reports electronically, has now been fully integrated under the E-Audit System structure. This consolidation creates a more robust and unified digital auditing platform in Turkey.
Although the use of the system is currently optional, it is strongly recommended by the authorities due to its efficiency. Tax inspectors may choose between traditional and digital methods during audits.
Why Is This Important for Companies?
Digitalization in tax auditing is no longer just a convenience — it’s a strategic necessity. For CFOs, financial controllers, and accounting departments, the E-Audit System offers:
- Faster, safer document submission
- Clear and traceable communication with auditors
- Reduced operational risk in compliance processes
- Full control over audit documentation from any location
- Improved response times to audit queries and findings
This transformation not only aligns with global trends but also strengthens tax compliance culture in Turkey.
Conclusion: Get Ready for a Digital Tax Audit Era in Turkey
With the launch of the E-Audit System, Turkey has entered a new phase in tax inspections. For businesses, this means a more efficient, faster, and transparent audit process — all powered by digital tools. Companies that adapt early to this transformation will gain a significant advantage in managing tax compliance effectively.
