A taxpayer under a tax audit has the right to be informed about the subject and scope of the audit, to ask that their statements be recorded in the minutes, to submit documents, and to request a hearing at the report evaluation stage. Exercising these rights does not remove legal obligations such as production of books and documents. An effective defense is built not by waiting for the outcome of the audit, but by creating written records at the notice, minutes and evidence stages. 1 2
An audit should not be seen only as a process for finding unpaid tax. Under Article 134 of the Tax Procedure Law No. 213 (VUK), the purpose is to investigate, determine and secure the accurate amount of tax due. For this reason, documents that favor the taxpayer must also be submitted for assessment. For example, when an amount booked as income is shown by documents to have been refunded, or an expense is shown to be directly connected with the conduct of the business, the audit's calculation of the tax base may change.
How does a tax audit begin and how is its scope determined?
What does the notice of commencement of an audit show?
Under current audit procedure, the start of an audit is notified in writing. Identifying the subject and scope of the audit in the notice helps the taxpayer understand which period and tax type to prepare for. The old view that “an audit does not begin until the commencement minutes are signed” should not be carried over automatically to current files. Article 140 VUK and the related audit regulation are the governing rules. 1 3
The first audit is carried out on the basis of the identity of the authorized person, the assignment, the type of audit, the period and the tax type. Later letters showing a change in scope should be attached to the first notice. A taxpayer's request for an explanation in order to understand the subject of the audit should not be treated as withholding information; however, a request for documents cannot be left unanswered on the ground that the scope is under discussion.
Where is the audit carried out?
Under Article 139 VUK, the audit is in principle carried out at the tax office. Where the conditions are met, an audit at the business premises may be requested. The nature of the commercial activity, the volume of documents, and any production or inventory processes that must be seen on site can be explained in the reasons for the request. The location of the audit is not a general justification for failing to provide the requested documents. 1
For transactions carried out electronically, it is important to clarify the transmission channel, file format and delivery record. Documents should not be considered submitted merely because they were sent to an employee's personal email account. A delivery and acknowledgment record in line with the procedure set by the administration should be kept.
What obligations apply to the production of books and documents?
How should a request for production be answered?
The production obligation under Article 256 VUK may cover the books and documents that must be retained, as well as the information needed to access electronic records. Check who made the request, which document is requested and what time is given. When documents are handed over, an inventory showing the period, type, number, digital file name and form of delivery reduces later disputes over whether a document was “not submitted.” 1 4
The fact that a document is not in the business's possession is not the same as the document never having been issued. Efforts should be made to obtain the records kept by the accountant, an archive company or an IT system, and the reason for the delay and the efforts to access the document should be recorded in writing. Entrusting the obligation to a third party does not automatically end the taxpayer's responsibility.
How should force majeure or a technical obstacle be documented?
If fire, serious illness, a natural disaster or a technical access problem is invoked, the date of the event, the records it covered and the link between the event and the production request should be set out. Force majeure under Articles 13 and 15 VUK must be distinguished from ordinary organizational difficulty. For a claimed server failure, service records, backup status, fault notifications and data recovery attempts can matter. Not every technical problem automatically constitutes force majeure. 1
A request for an additional period, with reasons, made before the deadline expires does not mean the request has been accepted. The administration's reply should be followed up; the part that can be produced should be submitted within the period and with a clear list. Destroying, altering or reconstructing documents contrary to fact is not a method of defense; it can have different and serious legal consequences.
Why do the audit minutes matter?
Draft minutes and the right to state one's position
The minutes are the basic record in which the facts established in the audit and the taxpayer's statements are recorded. The statement of rights issued by the Tax Inspection Board (Vergi Denetim Kurulu, VDK) notes that, upon request, a draft of the minutes may be made available to the taxpayer two days in advance and that objections may be entered in the minutes. 2 Requesting a draft is especially useful in files with many invoices or spreadsheets. For details on this subject, see the article on objecting to a tax audit minutes.
The minutes should separate the recording of facts from legal assessment. Against the statement that “the document was not produced,” you can state the date and receipt with which the document was previously delivered. Against the assessment that “the payment is a sales price,” if you argue that the amount was a loan, a shareholder debt or a refund, the supporting documents should be attached. A general entry “I object” does not explain which finding is wrong and why.
Should the minutes be signed, or is refusing to sign enough?
The meaning of a signature is assessed according to the content of the document. Statements that accept a material fact may later affect the defense. Findings that are not accepted, any calculation errors, and statements about submitting additional documents should be written out specifically. A copy of the minutes and its annexes should be obtained and kept.
Refusing to sign on its own does not stop the audit or invalidate the findings. However, signing does not mean giving up all tax consequences in advance. In practice, what matters is which fact the signed text accepts and on which points an objection is recorded. Especially where there is a claim of fake documents or unrecorded gross receipts, statements should be assessed together with the chain of documents.
How is a hearing before the report evaluation commission used?
The report evaluation process allows the report to be reviewed for compliance with legislation and procedure. The taxpayer must clearly record the request to be heard and follow the procedure notified to them. The Tax Inspection Board's rights page separately explains the right to request a hearing before the report evaluation commission. This process is not a lawsuit filed in court. 2 3 This subject is also covered in the article on what to do if the tax technical report is not served.
In preparing for the hearing, choose the disputed findings rather than a long narrative of events. Under each heading, you can show the assumption in the report, the counter-document, its effect on the calculation and the correction requested. Keep the acknowledgment of receipt for the letter sent for the commission's review, along with a list of the annexes submitted.
Example: gross receipts gap based on bank transactions
Consider a hypothetical company in which all bank inflows have been accepted as gross receipts. The taxpayer may argue that the same money movement was a transfer between accounts, that some payments relate to cancelled orders, and that some amounts are in the nature of shareholder debts. Each movement should be matched with the bank record, accounting voucher, counterparty and underlying contract.
The administration may argue that the documents were prepared after the fact, that the refunds did not take place, or that the debt relationship does not reflect reality. The defense must also answer this counter-possibility. A spreadsheet that is not verified by the underlying documents does not by itself prove the nature of a transaction. The evidence must together form a consistent economic explanation.
What happens if the audit period is exceeded?
Article 140 VUK sets the basic period as one year for a full audit, six months for a limited audit and three months for VAT refund audits; additional periods may be granted under legal conditions. The start date, extensions and notices should be checked against the file. It cannot be said that every audit lasting more than one year, or every report issued late, is automatically void. 1
Exceeding the audit period is different from the limitation period for assessment. The fact that an audit is ongoing does not mean that all assessment and notification periods are unlimitedly extended. The taxpayer should evaluate separately how the delay in the process affects their defense, and calculate the limitation period under its own heading. The fact that a report was prepared later does not by itself save a tax that had to be notified within its time limit.
What application routes exist after the report?
Is an objection to the report the same as a lawsuit against the notice of assessment?
The tax audit report is usually the basis for the tax and penalty decision. Where the report is a preparatory act, the main lawsuit is directed against the tax assessment or penalty notified by notice of assessment. Separate assessment is made for any other acts that produce independent legal consequences. The period for a lawsuit against a notice of assessment served after an objection to the report must not be put on hold. 1 5
The general period for a tax lawsuit is 30 days. The start of this period is determined by the rules on proper notification of the relevant act, not by the date on which the report was reviewed. Points contested in the report should be re-established by transaction and period in the petition.
Pre-assessment settlement option
Settlement options may be considered while the audit is ongoing; however, after Law No. 7524, the tax principal itself falls outside the new settlement regime. The scope of pre-assessment settlement, the time of the request and penalties outside its scope should be examined separately. It cannot be assumed that waiting for the audit to finish keeps all options equally open. 1 6
Settlement is not a proceeding in which every factual finding in the report is tested for accuracy. If the taxpayer's aim is to contest the tax base on the merits, the judicial route for the tax principal and the preparation of evidence should be preserved separately. Earlier and later settlement routes should not be seen as two unlimited rounds of negotiation. For details, see the article on settling tax penalties.
A practical working order for the audit file
- Put notices and notifications in date order, and mark changes in period and scope.
- Keep the delivery record of each document produced and an unchanged copy of the digital file.
- Match each of the administration's findings with a counter-document and its effect on the account.
- Tie the statements in the minutes, their annexes and the request for a hearing to a written record.
- After the report, track the notice of assessment, settlement and lawsuit timelines separately.
The legal assessment by the lawyer and the record-keeping and accounting work by the financial adviser (mali müşavir) complement each other. Even if the technical calculation is correct, a wrong procedural step can become the subject of litigation; even if the legal reasoning is strong, its effect on the tax base may remain undocumented. Joint work should prevent the same document from being explained inconsistently in different submissions.
Conclusion
In a tax audit, the defense is not limited to a single petition that begins once the report arrives. Understanding the scope of the notice, recording document production, making a specific objection in the minutes and preparing for the report evaluation stage in a documented way form the foundation of the process. While these rights are exercised, legal obligations and the time limits for any later lawsuit must be monitored together.
Frequently Asked Questions
Must the audit take place at my business premises?
No. The audit is in principle carried out at the tax office; where the conditions are met, an audit at the business premises may be requested. The distinction between place and delivery in the section “Where is the audit carried out?” should be considered. Back to the related section
Can I request a draft of the minutes in advance?
Upon request, there is a possibility of advance review. As explained in the section on the draft minutes and the right to state one's position, requesting the draft and its annexes makes it easier to make objections specific. Back to the related section
If the documents are with my accountant, does my production obligation end?
No. Delivery and access records should be created as described in “How should a request for production be answered?”; the fact that the documents are held by a third party should be explained within the period. Back to the related section
If I do not sign the minutes, does the audit stop?
Refusing to sign on its own does not stop the audit. As noted in “Should the minutes be signed, or is refusing to sign enough?”, it is important that a specific objection is recorded. Back to the related section
I have objected to the audit report; is a separate lawsuit needed?
If a tax or penalty is notified, the lawsuit period for it is assessed separately. The distinction in “Is an objection to the report the same as a lawsuit against the notice of assessment?” should be applied. Back to the related section
