What a self-employed accountant must file in Poland in 2026
This profile assumes a self-employed professional providing accounting or bookkeeping services, without employees, so it focuses on the tax and reporting calendar that applies to sole traders and small professional-services providers, plus any anti-money-laundering duties that apply to accountants specifically.
