Pretax is a Swedish tax advisory firm covering corporate tax, VAT, transfer pricing, transactions and tax litigation, with crypto assets and Web3 as a service line of its own. Its advisers come from the Swedish Tax Agency, the administrative courts and major audit firms, and the firm belongs to the international ECOVIS network. Its relevance lies in the fact that crypto tax rarely arrives alone: the questions surface inside ordinary corporate tax matters, from VAT on computing capacity to the treatment of gains on prediction markets.
