JTWPOLAND is a tax education portal created by licensed Polish tax advisors. We analyse PIT, CIT, VAT, restructuring, transfer pricing and cross-border settlements — from the perspective of practice.

What we do
Three forms of one mission: tax education without borders.
We create practical educational materials based on real advisory practice — for entrepreneurs, accountants, Poles living abroad and foreign nationals doing business in Poland.
Tax publications
We publish reliable articles and analyses in every area of tax law — PIT, CIT, VAT, transfer pricing and international taxation. We write accessibly, relying on legislation, case law and many years of advisory practice.
Tax training
We run online training for entrepreneurs, accountants and individuals who want to understand their tax obligations. Every session combines theory with practice — we discuss the rules using concrete, real-life examples.
See our training offer →Case studies
We present real settlement cases from different areas of tax law — from business activity, through rental and investments, to cross-border transactions. Step by step, with expert commentary.
Subject areas
From everyday settlements to complex transactions.
We are building a knowledge base in which plain language does not mean simplified analysis.
VAT
Invoicing, SAF-T (JPK), intra-Community acquisitions and supplies, import of services, chain transactions and cross-border settlements.
View materials →Restructuring
Mergers, divisions, conversions, contributions in kind and assessing the tax neutrality of reorganisations.
View materials →International taxation
Tax residence, permanent establishment, double tax treaties, working abroad, withholding tax and cross-border supply of services.
View materials →Transfer pricing
Thresholds, documentation, TPR reporting, safe harbours, intra-group financing and benchmarking.
View materials →Audits and disputes
Tax proceedings and audits, appeals, complaints to administrative courts and the practical rights of the taxpayer.
View materials →How we work with content
Source first. Then the conclusion.
Every piece is meant to take the reader from the legal rule to its practical application.
STEP 01
Legal status
We verify the applicable provisions and the date from which they apply.
STEP 02
Administrative practice
We analyse individual rulings, official explanations and the positions of the tax administration.
STEP 03
Case law
We check the lines of case law of the administrative courts and — where relevant — the CJEU.
STEP 04
Practical conclusion
We show the consequences, risks and possible courses of action.
Publications
