How to prepare your CEIDG-1 filing accurately in 2026

A Polish sole proprietorship (JDG) is the fastest legal structure for freelancers, B2B contractors and solo founders. Filing CEIDG-1 online at biznes.gov.pl costs 0 zł and simultaneously registers your tax ID (NIP), statistical number (REGON) and ZUS payer account.

Your key financial choices happen before submission: picking your income tax regime (lump-sum ryczałt, 19% flat tax or 12%/32% scale), claiming the 6-month Ulga na start ZUS relief and selecting valid PKD 2025 activity codes.

  • Within 7 days of your business start date, submit ZUS ZZA (health insurance only under Ulga na start) or ZUS ZUA (social + health insurance).
  • If your services require mandatory VAT registration or you invoice VAT-registered corporate clients, file VAT-R before your first taxable sale.
