A noticeable increase in the number of applications can be explained by the development of available contact channels from KAS. As indicated by Sebastian Polański from the Tax Administration Chamber in Wrocław, additional tools, such as the e-paragraph mobile application or the electronic form available on the website of the Public Information Bulletin of the Ministry of Finance, could encourage citizens to intervene.

Analysis and effectiveness of reports
Signal applications are analyzed and verified in detail before taking further action. As Anna Jasnosz, a spokeswoman for the Tax Administration Chamber in Kielce assures, each application, also anonymous, is subject to reliable assessment.

Sebastian Pakalski, spokesman for the Tax Administration Chamber in Gdańsk, the decision to respond to signal information is the responsibility of the competent head of the tax office or the Customs and Tax Office. However, the actions come first to analyze the information received. Then there may be verification, tax audit, customs and tax audit or other activities provided for in generally applicable law.
However, Agnieszka Jóźwin-Dalecka, spokeswoman for the Tax Administration Chamber in Opole, points out that Applications most often contain a description of various situations illustrating violations of tax law.
