Do you need a separate business bank account for a JDG?

No. No Polish law makes a sole trader (JDG, jednoosobowa działalność gospodarcza) open a separate business bank account, and giving any account in CEIDG is optional. Three rules still push many people towards one: the 15,000 PLN rule for payments between businesses, the VAT white list, and split payment. Whether they matter to you depends mostly on one thing: whether you charge VAT.

Is a business account a legal requirement?

Not for a JDG. You can take payments into your personal account (konto osobiste, also called ROR) if your bank’s terms allow business use. Read those terms: some personal accounts are for private use only, and the bank can end the contract.

A company is different. A sp. z o.o. is a separate legal person and, in practice, cannot work without an account in its own name.

What the law does require, for everyone, is that bigger deals go through an account:

• The 15,000 PLN rule. A single deal with another business worth more than 15,000 PLN must be paid or received through a payment account. This applies to every JDG, whether it pays or is paid.
• Instalments do not help. The value of the whole deal counts, however many payments you split it into.
• Foreign currency. A deal invoiced in EUR, USD or another currency is converted at the NBP (National Bank of Poland) average rate of the previous working day.
• Cash anyway? If the buyer pays in cash, it cannot book that payment as a cost.

These rules were in force on 24 September 2026. The 15,000 PLN rule says “payment account”, not “business account”, so on a plain reading a personal account in your name meets it.

The white list: why clients check your account

The white list (biała lista, officially Wykaz podatników VAT) is a free public register run by the tax authorities. It shows every business registered for VAT and the business bank accounts it has reported. You can search it on podatki.gov.pl or through biznes.gov.pl.

Your clients check it because of a rule aimed at them. When a business pays an active VAT payer more than 15,000 PLN for one deal, the account must be on the white list on the day the transfer is ordered. If it is not, the buyer:

• cannot book the payment as a tax-deductible cost, and
• becomes jointly liable for the seller’s VAT on it.

The buyer avoids both in one of two ways:

• it pays by split payment, or
• it files a ZAW-NR notice with its own tax office within 7 days of ordering the first transfer to that account. If the seventh day is a Saturday, Sunday or public holiday, the deadline moves to the next working day.

Many clients would rather not rely on that. They simply refuse to pay an account that is not listed.

Which accounts appear on the white list

If you are VAT-exempt (under the 240,000 PLN limit in 2026, see the VAT exemption limit), the white list cannot cause trouble, because the rule only covers payments to active VAT payers. If you are an active VAT payer and Polish clients pay you more than 15,000 PLN, you need a Polish business account that shows on the list.

Watch out: the income-tax part of this rule may end. A bill passed by the Sejm on 18 September 2026 and accepted by the Senate on 24 September 2026 would end the cost exclusion for invoices issued from 1 January 2027. Cash payments over 15,000 PLN would still be excluded, and the joint VAT liability stays. On 24 September 2026 the bill still needed the President’s signature, so treat it as not yet law.

Split payment needs a business account

Split payment (mechanizm podzielonej płatności, MPP) is a bank transfer in two parts. The net amount goes to your business account and the VAT goes to a separate VAT account (rachunek VAT). Banks open a VAT account automatically next to every business account. A personal account has none.

Split payment is usually voluntary. It is mandatory when an invoice is above 15,000 PLN gross and includes goods or services from annex 15 of the VAT Act, for example computers, laptops, phones, hard drives or construction services. A business with only a personal account cannot receive those payments.

The money on the VAT account is still yours. You can use it to pay your VAT, PIT (income tax), ZUS contributions and some other taxes. You can also ask the tax office to release it to your normal account; the office has 60 days to decide.

From 1 January 2027, when an active VAT payer pays another active VAT payer’s KSeF invoice by transfer, the transfer must also carry the invoice’s KSeF number (KSeF is the national e-invoicing system). This applies whichever account you use.

Fees, and why a separate account makes life easier

Fees depend on the bank and the plan, and they change often, so we do not quote them here. Before you choose, open each bank’s fee table (tabela opłat i prowizji) and compare what you will actually use:

• the monthly fee and the conditions for not paying it,
• domestic transfers and card payments abroad,
• currency conversion and incoming SWIFT transfers from foreign clients.

A separate account also makes the paperwork simpler:

• Your statement shows only business payments, so matching them with invoices at month-end is quick (see matching payments to invoices).
• Your accountant needs statements for every account the business uses. With one business account, that is one file instead of your private life.
• You can see at a glance what you owe for tax and ZUS.

Komplet, our free Mac app, reads PDF bank statements from any bank, pairs each payment with its invoice and shows which ones still have no document.

Do you need a EUR account for foreign clients?

No. A foreign client can pay into a PLN account and your bank converts the money at its own rate. A EUR account (konto walutowe) lets you receive euros without that conversion and decide when to change them, which is often cheaper.

For your income tax, it makes no difference where the money lands. Income in a foreign currency is converted to PLN at the NBP average rate of the last working day before the day of the revenue. Exchange rates on invoices explains how, and invoicing a foreign client covers what the invoice must say.

Can you use Wise or Revolut?

For foreign clients, yes. Many freelancers receive EUR, GBP or USD there and it works well. Keep two limits in mind:

• The white list. An account with a foreign IBAN is never on it. If you are an active VAT payer, give Polish clients who pay you more than 15,000 PLN a Polish business account instead. If your provider gives you a Polish (PL) number, search your NIP on the list before you rely on it.
• The 15,000 PLN rule. We found no official source confirming that a Wise balance counts as the “payment account” the rule asks for. For a large deal with a Polish business, use a Polish bank account, or ask KIS, the tax office’s information helpline.

Whatever you use, the statements are business records. Download them every month and give them to your accountant with everything else; see what to send your accountant.

For foreigners: if you have no other PLN payment account in Poland, a bank that offers personal accounts must offer you a basic payment account (podstawowy rachunek płatniczy). It may refuse if you are not legally resident in the EU, have no valid ID or give no address in Poland. That right covers personal accounts only. Business accounts are up to the bank; banks commonly ask for your NIP and REGON, and often a PESEL.

Adding the account to CEIDG

CEIDG, the public register of sole traders, has a section for bank accounts, and you can mark each one as business or personal. Only accounts marked as business can reach the white list, and only if you are registered for VAT.

• When you register: add the account in the CEIDG application, or leave it empty.
• When you open or close an account later: file a free change application (Zmień dane w CEIDG) on biznes.gov.pl. Changes to your CEIDG data are due within 7 days.
• After the change: search your own NIP on the white list and check the number is there before you send a large invoice.

When you suspend or close your JDG, the law says nothing about the account: you can keep it or close it. Keep the statements with your documents for as long as you keep your tax records (see closing a JDG).

What to do next

1. Find out whether you are VAT-exempt or an active VAT payer. That decides whether the white list matters to you.
2. If you charge VAT and invoice Polish businesses, open a business account at a Polish bank.
3. Add it to CEIDG with a change application, then find it on the white list.
4. If most of your clients are abroad, compare the fees of a EUR account at your bank with Wise or Revolut.
5. Keep business and private spending apart, and save every statement each month.
