I'm looking for a Bulgarian tax accountancy which can handle high frequency securities trading myself. Without success so far. Some names I came across: germania.bg, bsiservice.eu, mystartbulgaria.com, cocompany.io, Sb Accounting & Consulting, Kreston BulMar, Zaharinova Nexia
The less complex and more ordinary the business is with few transactions the easier it is to find one.
Rates are also among the highest i have seen in Europe.
