Your first month with a Polish JDG: a 2026 checklist for foreigners

What to do after CEIDG registration: ZUS, income tax, VAT, bank account, invoices, KSeF and records. A practical first-month checklist for foreign founders.

Your CEIDG entry is the start of the process, not the end. During the first month you need to check social insurance, income-tax method, VAT, invoicing and the flow of documents to your accountant. Foreign founders may also need to examine immigration status, tax residence and work performed for clients in other countries.

Start with the deadlines. Then set up a routine that will still work when the first invoices and expenses arrive.

Day one: verify your CEIDG entry

Check the public entry and confirm your start date, business name, addresses, PKD activity codes and chosen tax method. Make sure you have a legal right to use every address shown. NIP and REGON are normally added automatically, and CEIDG registration is free. Payment demands from private business registers are not official registration fees.

Within seven days: register for ZUS insurance

CEIDG sends your details to ZUS, which registers the business as a contribution payer. That does not always mean that you have correctly registered yourself as an insured person.

As a rule, within seven days of starting the business you submit:

ZUS ZUA if you are covered by social and health insurance, or
ZUS ZZA if you are registering only for health insurance.

You can include the form with the CEIDG application. Check separately whether you qualify for start-up relief or preferential contributions. Citizenship alone does not create an exemption.

If you also work in another EU or EEA country, do not assume that Polish contributions apply. Social-security coordination and an A1 certificate require a separate analysis.

Before the first sale: check VAT and VAT-UE

The standard Polish VAT exemption threshold is PLN 240,000 in 2026, reduced proportionally when you start during the year. Some activities cannot use the exemption.

Before issuing the first invoice, ask:

Is this activity excluded from the VAT exemption?
Would voluntary VAT registration make commercial sense?
Will the business buy foreign services, such as advertising or software?
Will it sell to EU businesses and need VAT-UE registration?

Even a VAT-exempt business can have obligations when importing services or trading across borders. Submit VAT-R before the transaction that requires registration. See our guide to VAT-UE registration for a Polish JDG.

Confirm the income-tax method

The tax scale, flat tax and revenue-based lump sum differ in how tax is calculated, how health contributions work and whether business expenses reduce the tax base. Under ryczałt, the rate follows the service actually performed and, where the law refers to it, the correct PKWiU classification. It is not a percentage you can choose freely.

Write down exactly what you sell, to whom and under what agreement. If you provide several types of service, your records must support the correct treatment. Compare the options in tax scale, flat tax or ryczałt for a JDG.

Build the first invoice around the transaction

Domestic sales, B2B services to an EU company and services exported outside the EU can require different invoice treatment. Before sending the first invoice, check:

your business details and NIP,
the VAT status of both parties,
currency and payment date,
an accurate description of the service,
the VAT rate or legal basis for not charging Polish VAT,
any wording required for a cross-border transaction.

Do not copy “reverse charge” from a random template without checking where the service is taxed.

Choose and report the right bank account

A separate business account is not compulsory for every JDG, but it can be required in practice for VAT, the Polish VAT whitelist or split payment. Your bank’s terms may also restrict business use of a personal account. If you add an account for the business, make sure it is reported correctly and matches the details used on invoices.

Set up a simple document workflow

From the first week, agree where invoices are uploaded, how unusual expenses are described, when the month closes, and how you receive tax and ZUS payment figures. Decide who checks foreign payments, exchange rates, contracts and evidence that a service was delivered.

This matters even more when documents are in several languages or payments move through different currencies.

Prepare for KSeF

Check when mandatory KSeF applies to your invoices. Choose invoicing software, arrange authentication and decide who will collect and account for documents from the system. Do not wait until the day your first mandatory invoice is due to grant access.

Check your tax residence

A Polish JDG does not determine your personal tax residence. If you split your year between countries, keep a home or family abroad, or manage the business from several places, review your day count, centre of vital interests and the relevant tax treaty. Use our separate tax-residency checklist for foreign JDG owners.
