Our company formation lawyers team explains what bookkeeping services in Türkiye entail, who needs them, key compliance obligations, and how professional support minimizes risk while enhancing financial clarity.

What Are Bookkeeping Services in Türkiye?

Bookkeeping services in Türkiye involve the systematic recording, classification, and maintenance of a company’s financial transactions in accordance with Turkish accounting standards and tax regulations. These services go beyond simple data entry and form the foundation of statutory accounting, tax compliance, and corporate reporting.

Core bookkeeping activities include:

• Recording daily financial transactions
• Maintaining general ledger and subsidiary accounts
• Tracking revenues, expenses, assets, and liabilities
• Managing invoices, receipts, and supporting documents
• Ensuring compliance with statutory chart of accounts
• Preparing monthly accounting records for tax reporting

Proper bookkeeping is mandatory for all companies established through company formation in Türkiye, regardless of size or sector.

Legal Framework Governing Bookkeeping in Türkiye

Bookkeeping in Türkiye is regulated primarily by:

• Turkish Commercial Code (TCC)
• Tax Procedure Law (VUK)
• Corporate Tax Law and VAT Law
• Communiqués issued by the Ministry of Treasury and Finance

Companies must keep their books in Turkish, in Turkish Lira, and in accordance with the official Uniform Chart of Accounts. Electronic systems such as e-ledger (e-Defter), e-invoice (e-Fatura), and e-archive invoice (e-Arşiv) are now standard for most businesses.

Failure to maintain compliant books may result in administrative fines, tax penalties, denial of expense deductions, and potential director liability.

Which Companies Must Maintain Bookkeeping Records?

All legal entities operating in Türkiye are subject to bookkeeping obligations, including:

• Limited liability companies (Ltd. Şti.)
• Joint stock companies (A.Ş.)
• Branches of foreign companies
• Liaison offices with taxable activities

Whether established through limited liability company formation or joint stock company formation, each entity must maintain statutory books from the first day of incorporation.

Even dormant or low-activity companies are required to keep books and submit periodic filings.

Scope of Professional Bookkeeping Services

At Finlexia Turkish Accounting Firm, bookkeeping services are delivered as part of an integrated compliance framework, closely coordinated with accounting, tax, and legal advisory teams.

1. Day-to-Day Transaction Recording

All commercial transactions are recorded accurately and timely, including sales, purchases, payroll entries, and bank movements. This ensures that financial data remains up to date and audit-ready.

2. VAT and Withholding Tax Tracking

Bookkeeping includes systematic tracking of VAT, withholding taxes, and deductible expenses, forming the basis for accurate tax declarations and minimizing exposure during tax inspections.

3. Bank Reconciliations

We reconcile bookkeeping records with bank statements obtained during bank account opening and ongoing operations, ensuring consistency between financial records and actual cash movements.

4. Monthly and Annual Closings

Periodic closings are performed to prepare companies for tax filings, management reporting, and statutory disclosures such as annual report filing obligations.

Bookkeeping and Corporate Governance

Accurate bookkeeping is an essential element of strong corporate governance

. Transparent financial records enable shareholders, directors, and investors to make informed decisions and fulfill their fiduciary duties.

Well-maintained books also support:

• Board reporting and resolutions
• Dividend distribution decisions
• Capital increases or decreases
• Share transfers and restructuring

Poor bookkeeping, by contrast, often leads to governance disputes, tax risks, and compliance failures.

Bookkeeping vs. Accounting: Understanding the Difference

While often used interchangeably, bookkeeping and accounting serve distinct but complementary functions:

• Bookkeeping focuses on recording and organizing financial data
• Accounting involves analysis, interpretation, and reporting

Bookkeeping forms the raw data layer upon which professional accounting & bookkeeping

services build tax returns, financial statements, and strategic insights.

Bookkeeping for Foreign Investors in Türkiye

Foreign-owned companies face additional challenges, including:

• Understanding local accounting rules
• Aligning Turkish books with group reporting standards
• Managing bilingual documentation
• Coordinating with overseas auditors

As an accounting firm working closely with Turkish company formation lawyers, we ensure that bookkeeping practices align with both Turkish regulations and international compliance expectations.

Our multilingual team bridges the gap between local statutory requirements and global reporting frameworks.

Digital Bookkeeping and E-Compliance in 2026

Türkiye continues to expand its e-compliance ecosystem. In 2026, most companies are required or encouraged to use:

• e-Invoice (e-Fatura)
• e-Archive Invoice (e-Arşiv)
• e-Ledger (e-Defter)

Professional bookkeeping services ensure correct system setup, compliant data entry, and timely submissions to tax authorities, reducing the risk of technical non-compliance.

Integration with Legal and Contractual Processes

Bookkeeping data directly supports legal processes such as:

• Drafting and reviewing commercial agreements
• Monitoring contractual payment obligations
• Supporting dispute resolution and litigation

Our integrated approach allows bookkeeping to align seamlessly with contract drafting & review services, ensuring financial and legal consistency across all corporate activities.

Common Bookkeeping Risks and How to Avoid Them

Businesses operating without professional bookkeeping support often face:

• Incorrect VAT calculations
• Missing or invalid expense documentation
• Late or inaccurate filings
• Exposure during tax audits

Outsourcing bookkeeping to experienced professionals significantly reduces these risks and allows management to focus on core business operations.
