Running a business in Poland means accounting and tax obligations – and for a foreigner there's also a language barrier and rules that differ from home. Investya provides full accounting in English (and other languages) for foreigners and foreign-owned companies – in any city in Poland.
What our accounting service covers
- full company accounting (books of account) and simplified accounting (KPiR, lump-sum),
- HR & payroll – contracts, payslips, ZUS registrations and settlements,
- tax returns (VAT, PIT, CIT), JPK files and KSeF e-invoicing,
- ongoing tax advisory and optimisation of your form of taxation.
Who it's for
- limited liability companies (Sp. z o.o.) with foreign capital,
- sole proprietorships (JDG) run by foreigners,
- people with cross-border income and foreign owners,
- startups and people using the business incubator.
