But as it happens, skilled entrepreneurs have found many ways to circumvent the issuance of legal invoices through loopholes in the law, and as one of the models is the issuance of bids rather than fiscalized invoices. They are also aware of this practice in the Ministry of Finance, and therefore, with the aim of better collection and control, they decided to introduce the printing of QR codes on each account, in order to make it easier to check the validity of the account. The model of fiscalization applied in the Republic of Croatia differs greatly from the model of fiscal cash registers, which is mainly applied by other countries, and such a model is recognized as a strong tool in the fight against tax evasion. The advantage of this model of fiscalization in relation to the application of fiscal cash registers is the fact that the tax authority knows about each issued invoice at the time of issuance and that each recipient of the invoice or each citizen can check the correctness of invoices using web services available from the Tax Administration. However, in accordance with the proposal, the introduction of a QR code would be introduced only from January 01, 2022. The question is whether the QR code will then be considered obsolete technology. But the introduction of a QR code will certainly make it easier to control your account, as it significantly speeds up the verification process. On the other hand, all taxpayers are already cooperating with the companies that maintain their programs, so this novelty should not be an additional cost or create any complications. The introduction of a QR code or verification of invoices via QR code would enable even better and better control of those taxpayers who do not fulfill their tax obligations on time and would achieve a fairer and more efficient tax system compared to other regular taxpayers, the Ministry of Finance concluded. By the way, the number of invoices issued in 2017 is around 2,345 billion, while in 2018 it is around 2,363 billion (therefore, a larger number of invoices was recorded). In the four seasons of organizing the prize game “No account is not counted”, about 40 million accounts were collected, which shows the interest of citizens in participating in checking the correctness of accounts, according to the Ministry of Finance. According to the draft law, in order to facilitate the verification of accounts by citizens, in addition to checking accounts via SMS or web service by entering the prescribed account data, it is proposed to prescribe checking accounts via Quick Response code (QR code). The use of QR codes, thanks to the mass use of mobile phones with cameras and Internet access, is widely used today by a large number of users. By reading the QR code shown on the invoice, all data would be entered into the application for checking the data from the picture, which would make the procedure easier for citizens and additionally encourage them to check the invoices and report them to the Tax Administration. And the new technology to be introduced is to print a QR code on each account The law on fiscalization has been in force in Croatia for six years, and this fall, with some changes, it will bring a novelty. Namely, according to the proposal of Amendments to the Fiscalization Act, the Ministry of Finance introduces the obligation to print a QR code on each account. Citizens, as the most important link in the successful implementation of fiscalization, recognized fiscalization as a positive measure that they support by taking and checking invoices and participating in the prize game “No invoice does not count”, says the description of amendments to the Fiscalization Act. As they point out from the Ministry of Finance on eConsulting, the application of the Act over six years has shown that the need to register all digits of the IAU or ZKI when checking invoices makes it much more difficult for citizens to check due to the large number of digits and the possibility of errors in transcribing digits. Following the progress and development of technology, it is necessary to find the possibility of checking the invoice by citizens without complex entry of the required items of the invoice today, including all digits of the IAU or ZKI.
