Audit Readiness & Year-End Close Support in Turkey
An audit should test the financial statements — not become the first time the company discovers that bank accounts are unreconciled, fixed-asset schedules are incomplete or intercompany balances do not agree. Audit readiness means closing the Turkish books before the auditors arrive and preparing the evidence, reconciliations and schedules they are likely to request.
Audit readiness in Turkey is the process of bringing the year-end accounting position to a supportable state before the independent auditor or group auditor begins fieldwork. For a foreign-owned subsidiary, this usually means completing the year-end close, reconciling material balance-sheet accounts, preparing tax and deferred-tax schedules, agreeing intercompany balances, organising supporting documents, building a PBC file and assigning owners for audit questions. SystemsCPA can support this preparation and auditor coordination without replacing the independent auditor.
What Is Audit Readiness?
Audit readiness is not the audit itself. It is management’s preparation of the accounting records, financial statements and supporting evidence so that the audit can proceed efficiently.
For a Turkish subsidiary, a strong audit-ready file connects four layers: the local accounting ledger, the year-end close, the applicable financial reporting framework and the evidence required to support material balances and transactions.
The SystemsCPA approach
We work from the trial balance outward. Each material balance should have an owner, a reconciliation, supporting evidence and a clear connection to the financial statements or group reporting package. Audit preparation is therefore treated as a finance-control project, not as a document-upload exercise.
Request a Pre-Audit Finance ReviewDoes Your Turkish Company Require a Statutory Audit?
Whether a Turkish company is subject to statutory independent audit depends on the applicable scope rules and the company’s facts. For 2026 and subsequent periods, KGK’s published guidance groups entities into different categories and applies different thresholds or automatic-scope rules.
For companies in the general residual category, the 2026 thresholds are based on exceeding at least two of the following for two consecutive accounting periods:
- Total assets: TRY 500 million.
- Annual net sales: TRY 1 billion.
- Employees: 150 or more.
Different thresholds apply to companies in certain specified categories, and some entities are subject to audit regardless of thresholds. The audit-scope analysis should therefore be completed against the current KGK rules rather than using only the general thresholds.
Why Audits Become Painful
Accounting issues discovered too late
- Bank accounts have not been formally reconciled.
- Old receivables or advances have no support.
- Fixed-asset additions do not agree to the register.
- Payroll liabilities do not tie to the ledger.
- Tax balances do not reconcile to filings.
- Intercompany balances differ from group counterparties.
Evidence issues discovered too late
- Contracts cannot be located.
- Invoices are missing or incomplete.
- Management estimates have no calculation file.
- Confirmation contacts are not available.
- Related-party documentation is fragmented.
- Year-end schedules are prepared only after the auditor asks.
The Year-End Close Before Audit
The year-end close should be more rigorous than an ordinary monthly close because it feeds statutory financial statements, tax computations, group reporting and the audit evidence file.
Lock the year-end cut-off
Identify invoices, goods, services, payroll costs and other transactions that economically belong to the closing period.
Complete bank reconciliations
Reconcile every material bank account and document outstanding or unusual reconciling items.
Close AR and AP
Prepare ageing schedules, identify old items, investigate credit balances and support material customers and suppliers.
Update fixed assets
Reconcile the general ledger to the fixed-asset register and verify additions, disposals and depreciation.
Reconcile payroll and employee liabilities
Tie year-end payroll expense and liabilities to payroll records and relevant filings.
Reconcile tax accounts
Support VAT, withholding, corporate tax, advance tax and other material tax balances with returns and working papers.
Agree intercompany
Obtain counterparty agreement for material related-party balances and document remaining differences.
Update provisions and estimates
Prepare support for accruals, employee benefits, impairments and other material management estimates.
Prepare current and deferred tax
Complete the current-tax bridge, deferred-tax schedule, tax-loss analysis and effective-tax-rate reconciliation where required.
Freeze the audit trial balance
Release a controlled year-end trial balance and document any subsequent audit adjustments separately.
What Should Be in the PBC File?
PBC means “prepared by client.” The exact auditor request list varies, but a well-organised Turkish subsidiary should be able to prepare most recurring schedules before formal fieldwork begins.
| Area | Typical PBC support | Control objective |
|---|---|---|
| Trial balance & GL | Final trial balance, detailed general ledger, chart of accounts. | Provides the core accounting population. |
| Bank | Bank statements, reconciliations, authorised bank list. | Supports cash existence and completeness. |
| Receivables | Ageing, customer detail, subsequent collections, impairment analysis. | Supports existence, valuation and recoverability. |
| Payables | Ageing, vendor detail, subsequent payments, unrecorded-liability review. | Supports completeness and cut-off. |
| Inventory | Inventory listing, count records, valuation support, slow-moving analysis. | Supports existence and valuation. |
| Fixed assets | Register, additions, disposals, invoices, depreciation schedule. | Supports existence, ownership and measurement. |
| Payroll | Year-end payroll registers, employee liabilities, reconciliations. | Supports personnel cost and liabilities. |
| Taxes | Returns, reconciliations, current tax computation, tax payments. | Supports tax assets, liabilities and expense. |
| Deferred tax | Tax-base schedule, temporary differences, tax losses, ETR bridge. | Supports IAS 12 / TFRS tax accounting. |
| Intercompany | Counterparty balances, confirmations, agreements, recharge schedules. | Supports related-party balances and transactions. |
| Equity | Capital records, shareholder resolutions, dividend documents. | Supports legal and accounting movements in equity. |
| Legal | Material contracts, litigation summary, lawyer correspondence where relevant. | Supports commitments, contingencies and disclosures. |
Auditor Confirmations: Prepare Before Fieldwork
KGK’s 2026 audit standards include BDS 505 on external confirmations. In practice, auditors may seek confirmations for banks, customers, suppliers, related parties, lawyers or other balances depending on risk and materiality.
The company can improve readiness by preparing:
- Complete bank account and bank-contact list.
- Customer and supplier contact details.
- Related-party entity list and responsible finance contacts.
- Legal counsel contact information.
- Signed authority forms where the auditor requires them.
- Reconciled balances before confirmation requests are sent.
A confirmation process should not be used to discover the company’s own balance. Management should already understand and reconcile the account before the external request is sent.
Opening Balances Matter in a First-Year Audit
KGK’s 2026 audit set includes BDS 510 specifically addressing opening balances in initial audits. This is particularly relevant where a foreign group has recently acquired a Turkish company, changed auditors or is subject to audit for the first time.
Management should be prepared to explain:
- How prior-year closing balances were derived.
- Whether prior periods were audited.
- Which opening balances remain subject to uncertainty.
- How historical tax and payroll balances were supported.
- Whether accounting-provider changes affected continuity.
If the company has recently changed accountants, see Accounting Takeover & Handover in Turkey.
Accounting Estimates Need a File, Not Just a Number
BDS 540 addresses the audit of accounting estimates and related disclosures. For management, the practical lesson is straightforward: any material estimate should have a documented methodology and evidence.
Examples can include:
- Expected credit loss / doubtful receivable estimates.
- Inventory obsolescence.
- Employee benefit obligations.
- Useful lives and residual values.
- Impairment assessments.
- Accrual estimates.
- Deferred-tax asset recoverability.
- Provisions and contingencies.
Related Parties and Intercompany: High-Friction Audit Areas
KGK’s audit standards include BDS 550 on related parties. For a multinational Turkish subsidiary, related-party activity is often one of the largest sources of audit questions because accounting, tax and transfer pricing overlap.
The year-end file should normally identify:
- All related-party counterparties.
- Nature of the relationship.
- Year-end receivable / payable balances.
- Revenue and expense by transaction category.
- Loans, interest and funding movements.
- Management fees and service recharges.
- Royalties or software charges.
- Material agreements and pricing basis.
- Transfer-pricing documentation status.
Intercompany accounts should be reconciled before the audit and before group consolidation.
Tax Provision and Deferred Tax Before Audit
Tax accounting is often one of the last areas completed at year-end, which makes it a common source of late audit adjustments.
The audit-ready package can include:
- Accounting-profit to taxable-profit reconciliation.
- Current corporate tax calculation.
- Domestic minimum corporate tax calculation where applicable.
- Advance tax and withholding-credit reconciliation.
- Tax-loss carryforward schedule.
- Deferred-tax schedule by temporary difference.
- Effective-tax-rate reconciliation.
- Support for uncertain tax treatments where material.
Local Statutory Accounts vs Group Audit Pack
A Turkish subsidiary may need to support more than one reporting output. The local financial statements may follow the reporting framework applicable in Türkiye, while the group auditor tests an IFRS or other group reporting package.
| Local audit support | Group / component audit support |
|---|---|
| Turkish statutory trial balance and financial statements. | Mapped group trial balance. |
| Local accounting policies. | Group accounting instructions. |
| Turkish tax balances and disclosures. | IFRS / group reporting adjustments. |
| Local related-party and legal records. | Group intercompany schedules and consolidation data. |
| Local statutory notes where applicable. | Component reporting questionnaire / audit pack. |
See Turkish Statutory Accounting vs IFRS and Management & Group Reporting in Turkey.
Audit Adjustments: Keep a Controlled Log
When the auditor identifies a proposed adjustment, the finance team should track it systematically rather than posting journals ad hoc.
| Field | Why it matters |
|---|---|
| Adjustment reference | Creates one source of truth for communication. |
| Account / financial statement line | Shows where the adjustment affects reporting. |
| Amount | Supports materiality assessment. |
| Reason | Documents the accounting issue. |
| Management response | Records agreement or disagreement. |
| Posted / unposted | Prevents mismatch between audited statements and ledger. |
| Tax effect | Identifies whether current or deferred tax changes. |
| Recurring control fix | Prevents the same audit adjustment next year. |

Frequently Asked Questions
What is audit readiness in Turkey?
Audit readiness is the process of completing the year-end accounting close and preparing the reconciliations, schedules, documents and management support needed before an independent or group auditor begins detailed fieldwork.
Does every Turkish company require an independent audit?
No. The scope depends on the current KGK rules and the company’s category and thresholds. Some entities are automatically in scope, while others become subject to audit based on specified asset, revenue and employee criteria.
What are the general audit thresholds in Turkey for 2026?
For companies in the general residual category, KGK’s published 2026 thresholds are TRY 500 million total assets, TRY 1 billion annual net sales and 150 employees, with at least two thresholds exceeded for two consecutive accounting periods. Different rules apply to other categories.
What is a PBC list?
PBC means “prepared by client.” It is the list of schedules, reconciliations, reports and supporting documents that management prepares for the auditor, such as bank reconciliations, AR/AP ageing, fixed assets, tax calculations and intercompany schedules.
Can SystemsCPA act as the independent auditor?
This service page describes audit preparation and finance support. The independent audit itself should be performed by the appropriately authorised independent auditor, with independence and professional requirements assessed separately.
Can SystemsCPA coordinate with our group auditor?
Yes. Depending on scope, SystemsCPA can prepare the local accounting support, group reporting schedules and PBC file and coordinate accounting questions with the group or component auditor.
What should be completed before audit fieldwork starts?
Material balance-sheet reconciliations, year-end cut-off, fixed assets, payroll, tax accounts, intercompany balances, current and deferred tax, major estimates and the core PBC schedules should ideally be completed before detailed fieldwork.
Why are opening balances important in a first-year audit?
Opening balances affect the current financial statements. KGK’s audit standards include BDS 510 specifically for initial audits and opening balances, making historical support especially important when a company is audited for the first time or changes auditors.
Can audit preparation help reduce audit adjustments?
It cannot guarantee that there will be no audit adjustments, but completing reconciliations, estimates and tax schedules before fieldwork generally makes accounting issues visible earlier and gives management more time to resolve them.
When should year-end audit preparation begin?
The strongest process begins before year-end with a pre-close plan, rather than after the auditor sends the PBC request list. Timing should be aligned with the company’s year-end, inventory counts, group close and audit timetable.
