Ex officio deregistration of a taxpayer record under VUK 160/A is not the deletion of the company from the trade registry, nor the extinction of tax debts. This measure, based on an analysis and assessment of the risk of issuing fake documents, directly affects the tax record and the conduct of commercial activity. The basis of the notified letter, the inspection visit, the decision process, the calculation of security and the time limit for an action must be examined together.
When a deregistration letter is received, two separate periods must be distinguished in particular: the one-month period provided under the statutory conditions for reinstatement with retroactive effect, and the 30-day period that, as a rule, applies to filing an action before the Tax Court, are not the same. One month is a period subject to calendar calculation; it cannot automatically be converted into 30 days. Talking to the administration does not, on its own, preserve these periods.
When does VUK 160/A apply?
Article 160/A of the Tax Procedure Law (Vergi Usul Kanunu, VUK) rests on a risk assessment carried out with data such as the duration of the taxpayer status, the size of assets and equity, the tax paid, the number of employees and the fulfillment of obligations. Taxpayers found to have a high risk of issuing fake documents are referred for examination and an inspection visit (yoklama) is carried out on them. After the visit and the assessment, the competent opinion and approval process provided for by the Law is run.
This mechanism does not mean that every low-turnover business or company with few employees is regarded as an issuer of fake documents. Being newly established, working predominantly in services, or procuring part of the work externally can be consistent with genuine commercial activity. However, such explanations need to be supported by contract, payment, delivery, personnel and capacity records.
The administration has authority to combat risk; the taxpayer, for its part, can argue whether the data used in the assessment belongs to it, relates to the correct period and is consistent with genuine activity. The action should be directed not only at whether risk analysis is generally useful, but at the legal and factual basis of the specific deregistration measure.
Why should VUK 160, 160/A and 153/A not be confused with one another?
The situations of ceasing business or the absence of activity in VUK 160 are not the same as the risk-based deregistration in 160/A. Article 153/A contains separate conditions as regards persons connected with taxpayer registrations established for the purpose of issuing fake documents and the security mechanism. The fact that 160/A refers to 153/A on some matters does not mean that all the conditions of the two articles are identical.
This distinction determines the basis of the defense. The conditions of another institution that rests on a completed inspection report cannot be transposed as they stand to a risk assessment at the stage of an incomplete examination. Conversely, a defense merely that “there is no final criminal conviction” does not of itself render a risk-based administrative measure void.
Which documents should be obtained when a deregistration letter arrives?
The first step is to keep the notification documents and electronic notification records. Next, the date of deregistration, the periods and documents from which it arises, the types of records it affects and how the security was calculated should be established in writing. The word “deregistered” seen on a screen does not explain the whole reasoning of the measure.
The inspection visit slip, the assessment and approval records, and the grounds of the measure that can be explained to the taxpayer should be requested. Where the administration may not share some elements of its risk analysis, a request that the court obtain these documents can be made in the statement of claim. For a defense to be possible, it is important that the specific reason for the deregistration can be argued; what data a general and abstract risk statement is based on should be investigated.
| Subject to examine | Document or record | Question from the defense perspective |
|---|---|---|
| Notification and time limit | Letter, envelope or electronic notification record | On which day did the period begin? |
| Actual activity | Rent, warehouse, energy, personnel and delivery records | Does the visit show the genuine business model? |
| Transaction volume | Invoices, bank, stock and contracts | Can the difference between volume and capacity be explained? |
| Competence and procedure | Opinion, committee and approval records | Was the measure established through the process in the Law? |
| Security | Calculation by period and document | Were the correct amount, the correct year and the correct total of documents used? |
| Effect on activity | Cancelled orders, system records, payment obligations | Can the need for interim protection be made concrete? |
How is genuine commercial activity demonstrated?
Unexplained differences between the record at the tax office and the business’s actual organization may create risk. If goods are kept at another address, the lease or logistics contract; if production is outsourced, the contract-manufacturing (fason) agreement and the shipment records; if a service job is carried out with few staff, the nature of the service and the use of outsourcing should be explained.
The mere existence of invoices and bank transfers does not conclusively establish the reality of transactions in every case. Delivery, performance of the service, stock movement, transport, customer communication and commercial capacity are assessed together. Conversely, the absence of staff at the workplace at a single moment of inspection does not automatically show that all activity is fake. Explanations such as working hours, work being carried out in the field or relocation should be documented.
For example, the fact that a trading company has no warehouse of its own despite a high sales volume may be explained in a business model in which goods are shipped directly from the producer to the customer. For this, not only a manager’s statement but consistency among orders, delivery notes, and transport and delivery records is needed. This hypothetical example does not mean that every business without storage is exempt from risk assessment.
Can taxpayer status be reinstated by providing security?
VUK 160/A provides a route for reinstatement of taxpayer status as of the date of deregistration, on condition that security of the prescribed type is provided within one month of notification of the deregistration letter and all tax debts are paid. In calculating the security, 10 percent of the total of documents issued in the periods when the risk of issuing fake documents was high, and the minimum amount to which the Law refers, are taken into account.
For 2026, the minimum security amount announced under 153/A in VUK General Communiqué Series No. 588 is 1,200,000 TL. The year on the basis of which the amount was calculated must be examined separately. It should not be assumed that the different paragraphs of 153/A or the provisions on an upper limit apply as they stand to the 160/A calculation; the assessment should be made on the scope of the reference.
What errors are investigated in the calculation of security?
The period described as risky and the documents included in the calculation should be matched. An allegation that a duplicate entry, a cancelled document or a transaction outside the scope was included in the calculation is shown by document number and amount. An objection that “the security is too high” does not by itself show a calculation error; the statutory basis, the period and the arithmetic are reviewed together.
The provision of security should not be framed as acceptance that the measure is lawful or as a waiver of the right to bring an action. The application, the guarantee given and the payment records should be set up consistently with the continued pursuit of the legal objections. Conversely, filing an action does not of itself mean that the conditions provided for by the Law are fulfilled.
Does reinstatement remove obligations for past periods?
No. The Law provides that the returns and notifications not filed in the period between deregistration and reinstatement are to be filed within one month of notification of the letter on reinstatement, and that the taxes that accrue are to be paid within the same period. Which notifications and returns remain outstanding should be checked in list form.
If the initial one-month application period has been missed, the conditions of the first route are not accepted as continuing of their own accord. The different possibilities regulated by Communiqué No. 520 regarding resuming business afterwards and related persons are examined according to the specific status. Reopening the company in another person’s name or changing the ownership structure in appearance only is not a safe legal solution.
How does deregistration affect invoices, contracts and debts?
Deregistration of the tax record does not end the company’s legal personality. The trade registry, employment contracts, leases and commercial contracts may continue under their own provisions. Existing public debts are not erased either. For this reason, a company halting all its obligations may give rise to new risks.
The restrictions arising on issuing electronic documents and on access to tax systems should be determined by reference to the relevant application and type of record. Continuing to operate in fact without re-establishing a lawful document system does not remove document and declaration obligations. Accounting records should be preserved; no untrue document should be issued through another business.
A deregistration record is not a definitive ruling that all invoices issued in the past are fake of their own accord. As regards the buyers’ deductions and expenses as well, the genuineness of the transaction and the relevant periods are examined. Nevertheless, the effect of the deregistration information on commercial relationships cannot be ignored; explanations given to customers should be accurate, proportionate and consistent with the documents.
How are the annulment action and the stay of execution prepared?
An annulment action before the Tax Court comes into play against the deregistration measure. Where no special period is provided, the general period is 30 days. Notification, becoming aware and the effect of the measure must be determined in the specific file. It should not be assumed that the time limit for an action stops automatically because of a reinstatement application or discussions with the administration; the conditions of İYUK 11 and the nature of the application are examined separately.
Filing an action does not of itself remove the deregistration record. This measure is not a tax assessment; carrying the rule on suspending collection over to it with all its consequences is wrong. If a stay of execution is sought, manifest unlawfulness and damage that is difficult or impossible to compensate must be explained together.
As to unlawfulness, wrong period data, an incomplete inspection visit, a failure to assess the business model, problems of procedure or competence, and the calculation of security can be addressed. As to damage, the obstruction of performance of contracts, documented loss of orders, personnel and rent obligations, and interruption of the document system can be shown. The same general statement of damage may not be sufficient for every business.
What is asked is that the court review the lawfulness of the measure, not that it take a commercial decision in its place. If a decision is obtained, its reflection in the tax records and electronic applications is followed up. Compensation for concrete damage arising from the annulled measure is separately assessed according to the damage, causation and the relevant procedural conditions.
How should the relationship with the examination and criminal process be set up?
A 160/A measure, a tax examination and, if there is one, a criminal investigation do not replace one another. The Tax Court’s annulment of the deregistration measure does not mean that every tax and criminal allegation automatically disappears. Likewise, having been deregistered is not a final finding of guilt in a criminal court.
The explanations given to the administration, the statements in the tax examination and, if any, the defense in the criminal file should be factually consistent. Documents of genuine activity should be preserved; creating documents afterwards should not be confused with proving past transactions. The possibilities of the return, set-off or other application of the security following the examination should also be followed separately.

Conclusion
Effective preparation in a VUK 160/A dispute requires comparing the specific data of the risk assessment with the business’s genuine activity. After notification, the time limits for reinstatement and for the action should be kept separate; the calculation of security, tax debts and returns for past periods should be managed together. A request for a stay of execution should show the documentable effect on activity as much as the unlawfulness of the measure.
Frequently Asked Questions
Does deregistration of taxpayer status mean the company has closed?
No. The tax record, the trade registry and the company’s legal personality are different. Deregistration does not of itself end existing debts and contracts. Related explanation
Is the one-month reinstatement period the same as the time limit for an action?
No. The one-month period is calculated by calendar month; the general 30-day period for an action is monitored separately. Complying with one does not of itself protect the other. Related explanation
If I provide security, do I lose my right to bring an action?
Providing security is not, on its own, a general waiver of the right to bring an action. However, the text of the application, the claims and the time limits should be prepared consistently with the continued pursuit of the legal objections. Related explanation
Does deregistration show that all old invoices are fake?
No. A risk-based record measure and the examination of the genuineness of a particular document are different. Each transaction is assessed with its own period and evidence. Related explanation
