VAT (podatek od towarów i usług — value-added tax) is one of the fundamental taxes every entrepreneur in Poland deals with on a daily basis. While the principle is straightforward — add tax to the net price and issue an invoice — practical questions arise frequently: which VAT rate applies to a given service, when must you register as a VAT payer, and how do you convert a gross amount to net? We answer all of these.
VAT Rates in Poland in 2026
Poland has four main VAT rates:
- 23% — the standard rate, applying to most goods and services.
- 8% — reduced rate: construction, selected catering services, over-the-counter medicines.
- 5% — reduced rate: unprocessed food, books, e-books.
- 0% — exports and intra-EU supplies (WDT/WNT).
Some services are VAT-exempt (ZW) — for example, medical, educational, and insurance services.
Formulas: Net → Gross and Gross → Net
This is the most common practical need:
- Gross price = net price × (1 + VAT rate)
Example: 1,000 PLN net × 1.23 = 1,230 PLN gross - Net price = gross price ÷ (1 + VAT rate)
Example: 1,230 PLN gross ÷ 1.23 = 1,000 PLN net
Common mistake: calculating net as "gross minus 23%". This is wrong! From 1,230 PLN you subtract 1,230 ÷ 1.23 × 0.23 = 230 PLN of tax, not 1,230 × 0.23 = 282.90 PLN.
When Must You Register for VAT?
VAT registration is mandatory when turnover exceeds 200,000 PLN per year (the subjective exemption threshold). However, registration is required from the very first invoice for certain activities, including:
- legal, advisory, or jewellery services,
- goods listed in Appendix 12 of the VAT Act,
- intra-EU acquisitions (WNT) exceeding 50,000 PLN.
What Must a VAT Invoice Include?
A valid Polish VAT invoice must contain: invoice number, issue date, seller and buyer details (NIP), description of the service/goods, net amount, VAT rate, VAT amount, and gross amount. Missing any element may be challenged by the tax authority.
