Abstract: In the author's scientific article "The need and prerequisites for conducting an unaccountable form of VAT calculation", potential opportunities for the practical application of a new concept of VAT calculation, the essence of which is to simplify the calculation procedure, consisting in the abolition of a number of requirements, rules and procedures. The tax authorities will only issue electronic invoices, according to which the authorities will calculate the tax automatically.
The new concept will entail a change in the procedure for calculating tax and its administration, which may lead to incorrect calculation of tax and may cause an increase in shortfall in state revenues, which requires a preliminary calculation of such losses. Since there are many rules and benefits, losses can be obtained from each such factor, which requires an analysis of state revenues for each article.
The purpose of this work is to identify VAT transactions with the maximum risk of incorrect calculation of VAT by the tax authority on the invoice.
The main conclusion in this work is the presence of risks of incorrect filling of the taxpayer's invoice and calculation of tax by the tax authority at the level of 30%, which is explained by the fact that about 70% of invoices do not contain features and subtleties, but are compiled as a general rule in the form of applying a tax rate of 20% to each sale according to the corresponding the invoice. However, these risks can be minimized by minor revision of the invoice without significant addition of new details, since each additional detail entails the risk of incorrect filling in, which increases the likelihood of erroneous registration of the document.
