More and more often, Director of the National Tax Information (KIS) refuses to issue individual interpretations. The basis for such decisions is the justified suspicion that the activity described by the taxpayer may be considered as tax avoidance (i.e., Article 119a § 1 of the Tax Ordinance). Recently, such decisions have been issued particularly frequently in case of the provision of services (B2B) to a company by a member of its management board. The tax authorities’ change in approach is particularly noticeable in the case of entrepreneurs applying for an interpretation regarding the appropriate lump-sum rate.
