Accounting Practices and Mandatory Reporting in Türkiye: The 2026 Landscape
Accounting Software Ecosystem
In Türkiye, company accounting and financial management processes are now fully dependent on digital infrastructure. As of 2026, accounting software is grouped into three main categories:
- Commercial accounting and ERP programs: feature modular structures with advanced inventory and production management
- Software for certified public accountants (SMMM) offices
- Cloud-based accounting and pre-accounting platforms
Selecting the right software has become a strategic decision mechanism. The proper platform enhances financial control, improves reporting quality, and ensures easier regulatory compliance.
Mandatory E-Transformation Applications
By 2026, several e-transformation systems have become mandatory for all businesses in Türkiye:
E-Invoice and E-Archive Invoice: Paper invoices are entirely abolished. Regardless of amount, every invoice must now be issued electronically as an e-invoice or e-archive.
E-Ledger: Companies keeping books on the balance sheet basis must use the e-ledger system. Initiated in 2025, full compliance is mandatory from 2026 onward.
E-Dispatch Note (E-İrsaliye): This digital transformation tool continues to expand its coverage progressively.
Due to their compatibility with bank integrations and automated data flows, cloud-based SaaS accounting solutions have become the preferred tools for businesses adapting to these changes.
Türkiye Sustainability Reporting Standards (TSRS)
Legal Framework and Threshold Values
The Türkiye Sustainability Reporting Standards (TSRS) system became mandatory on January 1, 2024. Threshold values were redefined for reporting periods starting January 1, 2025. Developed by the Public Oversight, Accounting and Auditing Standards Authority (KGK), TSRS aligns fully with the global ISSB S1 and S2 standards.
Mandatory Scope:
Businesses exceeding at least two of the defined thresholds for two consecutive reporting periods are subject to mandatory reporting requirements. This includes:
- Companies subject to independent audits (excluding banks)
- Banks (except those under the Savings Deposit Insurance Fund)
Reporting Content: Companies must provide financial performance data together with ESG (Environmental, Social, and Governance) indicators, as summarized below:
| Mandatory Reporting Areas | Implementation Details |
|---|---|
| Carbon emissions and greenhouse gases | Reported in TFRS-compatible format |
| Energy consumption | Requires independent auditor approval |
| Social impact indicators | Integrated into financial statements |
| Carbon footprint | Included in annual reports |
Alignment with Global Standards
As TSRS is internationally compatible, Turkish enterprises can present data comparable to global investment norms. This alignment is particularly valuable for exporters and companies attracting foreign investors, ensuring operational transparency and competitive credibility.
Financial Advisors and Audit Practices
Digital Auditing: By 2026, digital tools and artificial intelligence have become mandatory in auditing processes. Tax inspections widely rely on AI-supported systems to enhance accuracy and efficiency.
SMMM Office Responsibilities: The role of certified public accountants has significantly expanded and now includes:
- Maintaining general ledgers and sub-ledgers in compliance with the Uniform Chart of Accounts
- Managing payroll and social security (SGK) transactions
- Advising on e-transformation and regulatory compliance
Financial Reporting Standards (TFRS 2026)
The Turkish Financial Reporting Standards (TFRS) 2026 Set defines the accounting principles valid for Turkish companies. These standards ensure consistency with the International Financial Reporting Standards (IFRS), supporting cross-border compatibility and transparency in financial reporting.
