The Revenue Administration, which has entered a new phase in the fight against the informal economy, analyzes 4 million taxpayers daily with the KAŞİF application it has implemented to combat fake documents. Minister of Treasury and Finance Mehmet Şimşek stated, "We have entered a new era in the fight against informality. With new technologies such as artificial intelligence and machine learning, we can now instantly detect all informal activities and take action. I invite all our taxpayers to remain within the records."
The Ministry of Treasury and Finance has started to scan 4 million taxpayers daily by launching the AI-supported analysis application KAŞİF to combat fake invoices, also known to the public as nylon invoices.
The Ministry, which continues its fight against the informal economy without interruption, has taken a new step in the fight against fake invoices that are issued as if there were real goods delivered or services provided, even though this is not the case.
The Revenue Administration (GİB), which conducts its fight against fake documents with the rule-based Fake Document Risk Analysis Program (SARP) and the Risky Refund Tracking and Analysis Program (RİTAP), has entered a new phase in this struggle.
Those who issue fake documents and request unjust refunds are now being monitored day by day with the AI-based analysis application KAŞİF.
The new risk analysis application KAŞİF, based on machine learning and artificial intelligence technologies, was developed by the GİB Technology unit of the Presidency and the TÜBİTAK Artificial Intelligence Institute.
Not operating on a rule-based system, KAŞİF reveals risky situations by analyzing large data sets daily through its embedded AI model without any prior definitions or rules. Changes in taxpayer behavior are automatically detected by KAŞİF, and each new situation is re-analyzed to identify risky taxpayers.
"4 MILLION TAXPAYERS ARE ANALYZED DAILY"
With KAŞİF, which operates on big data platforms and analyzes data from dozens of terabytes, approximately 4 million taxpayers are analyzed daily.
By monitoring dozens of different information and situations across many categories, risky situations are identified much more quickly and accurately.
Data related to many headings such as tax liability, invoices, accruals, collections, imports, exports, declarations, notifications, business and production capacity, employees, and fixed assets are analyzed, and risky situations are reported daily.
Thanks to the application, which has the ability to detect risky situations by autonomously sensing changes in taxpayer behaviors and other information, those who issue fake documents and request unjust refunds can be identified quickly and accurately.
COMPANIES ESTABLISHED TO ISSUE FAKE DOCUMENTS ARE IDENTIFIED ON THE SAME DAY
As soon as KAŞİF was implemented, it made significant detections regarding taxpayers with a high risk of issuing fake documents on the same day.
For example, a taxpayer who operates in wholesale trade and issued 3 different invoices on the day they established their tax liability without any purchases was identified.
On the 5th day following the establishment date, a taxpayer who issued 5 fake invoices worth 50 million lira was identified among different taxpayers with a high risk of issuing fake documents.
It was determined that 6 out of 7 companies established in different tax offices under the name of a person employed in a company aimed to issue fake documents. The total amount of invoices issued by these companies was calculated to be 246 million lira.
It was found that 2,550 taxpayers, who were established in the last 3 months and issued invoices totaling 276 billion lira, had a high risk and were established for the purpose of issuing fake documents without any commercial, agricultural, or professional activities.
It was understood that the VAT refund amount of 7.7 million lira reported by a taxpayer in their declaration was unjustified.
RISKY TAXPAYERS ARE REFERRED FOR TAX AUDIT AND REPORTED TO TAX OFFICES
Taxpayers identified as having a high risk of issuing fake documents are reported to the Tax Audit Board for the purpose of conducting a tax audit.
These taxpayers are also communicated to their respective tax offices, where inspections are conducted at their workplaces, and records of those who established tax liabilities for the purpose of issuing fake documents are closed based on the decisions made by the commission established in the tax offices.
MINISTER ŞIMŞEK: WE DETECT IMMEDIATELY, WE TAKE ACTION
Minister of Treasury and Finance Mehmet Şimşek stated that the latest technology applications have made the fight against the informal economy more effective, saying, "We have entered a new era in the fight against informality. With new technologies such as artificial intelligence and machine learning, we now detect all informal activities instantly and take action. I invite all our taxpayers to remain compliant."
Emphasizing that the Revenue Administration continuously renews its risk analysis infrastructure, Şimşek stated, "With these applications, we will continue to effectively combat the informal economy and prevent inconsistencies that create unfair competition."
