Well, in order for the tax office not to impose a penalty on us, a company that uses higher “copyright” costs must include a provision in the employment contract with an IT specialist about the transfer of copyrights to the employer.

The most common mistake is concluding a contract in a form other than written. Meanwhile, in accordance with Art. 53 of the Copyright and Related Rights Act, “an agreement on the transfer of copyrights must be in writing under pain of nullity.” Therefore, it will be important and effective to conclude the agreement and sign it by hand or with a qualified electronic signature – entrepreneurs in the IT industry very often forget about this.

Pursuant to Art. 30 and 26a of the Tax Ordinance, the tax collector (i.e. the employer) may be liable for the tax not collected in the event of any errors, up to the amount of the advance payment that he was obliged to collect. In other words, it is in the employer’s interest that the solution in question is implemented correctly, because it is ultimately the employer who is responsible for it


We support our clients (individuals) by verifying the possibility of applying 50% of tax-deductible costs. The analysis of the contract and the activities actually performed is of great importance. During consultations, we also ensure the maximum possible level of protection for such taxpayers.

As for clients who would like to implement 50% KUP in their companies (i.e. employers), it is usually necessary to analyze the concluded contracts and the activities actually performed, prepare appropriate calculations, and introduce a procedure for valuing and transferring copyrights. In more complex cases, we help in introducing contractual changes, preparing appropriate evidentiary procedures, coordinating accounting work and assisting in preparing an application for the tax ruling.
