PETERKA & PARTNERS represented an international humanitarian organization, operating in 70 countries, on VAT aspects of a shared services centre. The tax advisory consisted in the application of VAT exemption on cost sharing, which is unique as very little relevant EUCJ case law exists and the exemption was in practice impossible. PETERKA & PARTNERS represented the client with an analysis of the breaking EUCJ case law which is binding in the Czech Republic, preparation of appropriate requests and negotiations within the Coordination Committee, i.e., the regular meetings between the Chamber of Tax Advisors and the General Financial Directorate which is a superior body to the Czech tax authorities. We obtained a positive and clear opinion beneficial for the client in terms of claiming input VAT deduction.
