Specialists of Pragnum Law Firm protected the Client's interests in the dispute over appeal from the tax assessment notice and proved that the tax payer did not have to be liable for tax discipline of its contracting parties. The lawyers provided the evidence base refuting the arguments of the tax authority regarding the Client's incapability of referring the amount to the VAT credit against tax as the contracting party had not declared its liabilities within mutual relations with the Client. Therefore, the court upheld the Client's opinion and revoked the contested tax assessment notice.
