The fundamental objective is to specify the areas and scope of tax relief application by Polish production companies operating in the agricultural machinery sector. The main burden of the study was placed on a literature query of the available documentary and literature sources and an expert debate on the legal aspects of tax relief (desk research analysis of existing data, such as: organizational documents, legal acts, research reports and publications in R&D and commercialization of knowledge). In order to refer the issue to the agricultural machinery sector, the analysis also used the results of a survey conducted among a deliberately selected group of enterprises, in which the respondents provided answers regarding aspects of tax relief and the scope of its application, articulated during the consultations. Since companies indicate that the greatest problems are caused by uncertainty whether their activities qualify for the relief and a high risk of the tax authority questioning the deduction, a study was developed in response, which provided general knowledge in the field of tax law. Thus - bringing the scope and possibilities of applying the tax relief closer – the needs and expectations of entrepreneurs were identified and good practices were proposed that are a response to the demands of the digitizing economy. However, the objective impossibility of fully developing all the threads of the undertaken (quite complex) problem implies the necessity of a synthetic presentation of the cited threads.
