Do You Need a Polish Bank Account to Register a Foreign Company for VAT in Poland?

September 29, 2025

Foreign companies entering the Polish market often face a crucial question: is a domestic Polish bank account required to register for VAT? In this update we explain when VAT registration is necessary, what benefits it provides, how EU rules differ from Polish practice, and why recent regulatory changes — including mandatory e-invoicing (KSeF) — make it essential to check that your accounting partner is technically prepared.

1. When Must a Foreign Company Register for VAT in Poland?

Before the first taxable transaction

Under Polish law, a company must register for VAT before carrying out its first taxable transaction in Poland (unless exempt under thresholds).

According to the Polish government portal Biznes.gov.pl:

“You should submit the VAT-R registration form before you make your first taxable supply in Poland.”
(Biznes.gov.pl – Registering as a VAT taxpayer)

Typical cases when foreign VAT registration is required

Selling goods stored in Poland to local customers.
Installation or assembly services performed in Poland.
B2C sales into Poland above EU thresholds (if OSS is not applied).
Transactions not covered by reverse charge.

Advantages of Polish VAT registration

Right to deduct input VAT on Polish costs and imports.
Ability to issue invoices with Polish VAT, improving credibility with local clients.
Access to refunds of surplus VAT.
Clear compliance with Polish tax rules, reducing audit risk.

2. Do EU Rules Require a Domestic Bank Account?

The EU VAT Directive (2006/112/EC) does not impose an obligation for VAT-registered businesses to hold a bank account in the Member State of registration. In most EU countries, VAT registration is possible without opening a local account.

However, Poland has unique requirements:

VAT refunds are only paid into a bank account located in Poland, belonging to the taxpayer.
The split payment mechanism (mechanizm podzielonej płatności) requires a dedicated Polish VAT sub-account, available only in Polish banks.
All VAT reporting in Poland is handled electronically (JPK_V7 files) and linked to domestic banking systems.

This means that, while not explicitly written in EU law, in practice a Polish bank account is indispensable for full VAT compliance and refunds.

3. 100% Digital VAT Reporting in Poland

Poland is among the most advanced EU countries in terms of digital tax administration. All VAT returns are filed electronically via JPK_V7 files. Refunds, split payment transactions, and verification of bank accounts are fully integrated into electronic systems.

Foreign businesses must therefore ensure:

They can provide valid Polish bank account details during VAT registration.
Their accountants or tax agents are able to file JPK_V7 correctly and on time.
They are ready for ongoing digitalization of tax processes.

4. New Mandatory E-Invoicing (KSeF)

Timeline of KSeF implementation

Poland is introducing the National e-Invoice System (KSeF), which will make e-invoicing mandatory for all taxpayers. According to the Ministry of Finance:

“Mandatory use of KSeF will apply from 1 February 2026 for large entities and from 1 April 2026 for all other taxpayers.”
(gov.pl – Ministry of Finance: Mandatory KSeF postponed to 1 February 2026)

Key dates:

1 February 2026 – large taxpayers (annual sales > PLN 200m).
1 April 2026 – all other businesses, including SMEs and foreign VAT registrants.

Practical consequences

All invoices must be issued in structured XML format via KSeF.
Traditional PDF or paper invoices will no longer be valid.
Split payment transfers will eventually require the KSeF invoice number in the payment title (planned from 2027).
Businesses must integrate their ERP/accounting systems with the KSeF API.
Failure to comply may lead to fines, though a transition period is expected.

Why this matters for foreign companies

Foreign VAT registrants in Poland must also comply with KSeF rules. This means:

Their accounting service provider must be technically prepared for KSeF integration.
AI-powered or automated accounting systems must be updated for real-time invoice reporting.
Companies should verify that their service providers are KSeF-ready to avoid penalties and disruption of operations.

5. Action Points for Foreign Businesses

Register for VAT in Poland before the first taxable supply if your business activities trigger the obligation.
Open a Polish bank account — necessary for VAT refunds and split payment compliance.
Ensure all VAT reporting (JPK_V7) is filed electronically and correctly.
Prepare for KSeF mandatory e-invoicing in 2026 by checking your accounting provider’s readiness.
Consider using AI-ready accounting systems that can automate VAT filing, split payments, and e-invoicing integration.
