Scope of Our Accounting Services
Celikel CPA provides end-to-end accounting services that extend well beyond routine ledger entries. Our framework addresses every financial reporting obligation mandated by the Turkish Commercial Code (TCC), Tax Procedure Law (TPL), and internationally recognized standards such as IFRS and TAS. Below are the core pillars of our service offering:
Statutory Bookkeeping and Ledger Management
We maintain your legal books (Journal, General Ledger, and Inventory Book) in full compliance with the Tax Procedure Law (Law No. 213) [1] and administer all postings through the e-Ledger (e-Defter) system mandated by the Revenue Administration (GIB). This includes chart-of-accounts alignment with the Uniform Chart of Accounts published by the Ministry of Finance.
Financial Statement Preparation (TAS/IFRS)
We prepare balance sheets, income statements, cash flow statements, and statements of changes in equity in accordance with Turkish Accounting Standards (TAS), BOBI FRS (Financial Reporting Standard for Large and Medium-Sized Entities), and IFRS for entities with international stakeholders [2]. Reports are delivered in Turkish and English as required.
Tax Return Filing and Compliance
Preparation and electronic submission of all periodic tax declarations: monthly VAT returns, withholding tax (stoppage) declarations, quarterly advance corporate tax returns, annual Corporate Tax and Income Tax returns, and Stamp Duty declarations [3]. We ensure timely filing to avoid penalty surcharges and loss-of-tax penalties (Vergi Ziyai Cezasi).
Inflation Accounting and Restatement
Under the inflation adjustment provisions reactivated per Law No. 213, Provisional Article 33, we apply CPI-based restatement to your non-monetary balance sheet items. This process helps prevent taxation of fictitious profits caused by inflationary distortions and preserves the real economic value of your equity.
Additional Integrated Services
Beyond core accounting, our team also handles e-Invoice (e-Fatura) and e-Archive Invoice integrations, e-Waybill (e-Irsaliye) configurations, Ba-Bs reconciliation forms, and annual activity report preparation. These auxiliary compliance services are managed seamlessly as part of your accounting engagement.
Who Needs Professional Accounting Services in Turkey?
Turkey's regulatory environment demands meticulous record-keeping and timely reporting from every commercial entity. Professional accounting support is not merely a convenience; for most business structures, it is a legal necessity.
1. Foreign-Owned Companies and International Subsidiaries
- Companies established under the Direct Foreign Investment Law (Law No. 4875) [4] that must report in both Turkish GAAP and their parent entity's reporting framework (IFRS, US GAAP).
- Branch offices, liaison offices, and free zone entities requiring separate statutory books alongside consolidated group reporting.
2. SMEs and Domestic Corporations
- Limited liability companies (Ltd. Sti.) and joint-stock companies (A.S.) obligated to maintain legal books and file periodic declarations under the TCC and TPL.
- Sole proprietors and self-employed professionals who need organized financial records for income tax compliance and potential audit defense.
3. Growing Enterprises Seeking Institutional Structure
- Businesses transitioning from basic bookkeeping to structured management accounting, budgeting, and KPI-driven financial dashboards.
- Companies preparing for independent audit thresholds, IPO readiness, or investor due diligence where clean, IFRS-aligned financials are critical.

2026 Regulatory Landscape
The Turkish accounting ecosystem in 2026 is shaped by continued inflation accounting requirements, expanded e-Document mandates (e-Invoice, e-Ledger, e-Waybill), and evolving sustainability reporting obligations under ESG frameworks. Businesses that fail to adapt their accounting infrastructure risk material misstatements, regulatory penalties, and loss of creditor confidence.
How Does Our Accounting Process Work?
We follow a structured, technology-driven methodology designed to minimize disruption to your operations while maximizing accuracy and regulatory compliance.
Onboarding and Diagnostic Review
We conduct an initial assessment of your existing accounting records, chart of accounts, ERP or software environment, and pending tax obligations. Any historical discrepancies or backlogs are identified at this stage.
System Configuration and Chart of Accounts Alignment
Your chart of accounts is mapped to the Uniform Chart of Accounts (Tek Duzen Hesap Plani) required by Turkish law. We configure your e-Ledger, e-Invoice, and e-Archive integrations with the Revenue Administration (GIB) portal where applicable.
Ongoing Transaction Recording and Declaration Filing
All purchase invoices, sales records, bank transactions, payroll entries, and expense vouchers are posted to your legal books on a continuous basis. Monthly VAT returns, withholding declarations, and Ba-Bs forms are prepared and electronically filed before statutory deadlines.
Period-End Closing and Financial Reporting
At each quarter-end and fiscal year-end, we close the books, apply inflation accounting adjustments (where applicable), prepare statutory financial statements, and deliver management reports. Annual corporate tax returns and supporting schedules are filed within regulatory deadlines [3].
Audit Support and Continuous Advisory
We provide documentation packages for independent auditors, respond to tax authority inquiries on your behalf, and deliver quarterly compliance health checks. Our team proactively alerts you to legislative changes, new incentive programs, and restructuring opportunities published in the Official Gazette.
Regulatory Framework and Tax Compliance Risks
Operating a business in Turkey without properly maintained accounting records can result in significant financial and legal consequences. Below are the key risk areas that underscore the importance of professional accounting support:
Loss-of-Tax Penalties (Vergi Ziyai Cezasi)
Under the Tax Procedure Law (Law No. 213, Article 341) [1], any act that leads to a reduction or delayed collection of tax triggers a loss-of-tax penalty equal to one times the unpaid tax amount, plus late payment interest calculated at monthly rates set by the Ministry of Treasury and Finance. In cases involving willful evasion, the penalty can triple.
Irregularity Fines for Late or Missing Declarations
Failure to file VAT returns, withholding tax declarations, or annual tax returns by the statutory deadline results in special irregularity fines (Ozel Usulsuzluk Cezasi) under TPL Article 352. Late e-Ledger submissions or failure to issue e-Invoices attract additional administrative penalties that accumulate per occurrence.
Criminal Liability for Fraudulent Records
Maintaining fictitious invoices, double books, or deliberately concealing transactions can lead to criminal prosecution under TPL Article 359, carrying imprisonment sentences. Company directors and authorized signatories bear personal criminal liability in such cases.
Blocked Access to Government Incentives
Entities with outstanding tax debts or incomplete filings may be disqualified from R&D incentives (Law No. 5746), KOSGEB grants, investment allowances, and export subsidies. Additionally, banks typically require clean tax compliance certificates (Borcu Yoktur Belgesi) for corporate credit applications.
