How to Fill Out the CEIDG-1 Form Step by Step to Register a Sole Proprietorship in Poland

Why the CEIDG-1 Form Matters

The CEIDG-1 form is the single document required to register a sole proprietorship in Poland (jednoosobowa działalność gospodarcza). Submitting it correctly through the official Central Registration and Information on Economic Activity (CEIDG) portal at gov.pl/ceidg is free and fast. However, even a simple mistake – like an incorrect PKD code or a mismatched signature – can delay your registration by several days. This guide explains each step with official references and gives you a checklist to use immediately after submission.

What You Need Before You Start

Gather these items before logging into the CEIDG system:

• Valid Polish ID card (dowód osobisty) or passport – required for authentication via trusted profile (Profil Zaufany) or e-ID.
• Your PESEL number (non-Polish citizens without PESEL need passport number and residence document).
• Address of residence and a separate correspondence address (optional – useful if you want to keep your home address private).
• Primary PKD code – use the official PKD search tool on the website of the Polish Statistical Office (GUS): stat.gov.pl/klasyfikacje/pkd_2007/.
• Choice of tax form: general tax scale (skala podatkowa), flat-rate tax (19%), or lump-sum tax (ryczałt). Rates and limits are explained on Biznes.gov.pl.
• Business start date – must be the same day as you submit the form or later. Retrospective dates are not allowed.

Step 1: Log In and Select Registration Mode

Navigate to gov.pl/ceidg and click “Zarejestruj działalność gospodarczą” (Register economic activity). You can log in using:

• Profil Zaufany (trusted profile) – the most common method.
• e-Dowód (electronic ID card) – requires a card reader.
• Qualified electronic signature.
• Online banking if your bank supports the IDP system (list available on the CEIDG main page).

After logging in, the system automatically pulls your personal data from your profile. Verify that your name, surname, and PESEL match your ID card exactly. If any field is incorrect, correct it before proceeding.

Step 2: Fill in Applicant Data

Complete only the fields not pre-filled. Pay close attention to:

• First and last name – must match your ID document.
• PESEL number.
• Residence address – if you do not want this to appear in the public CEIDG registry, enter a different correspondence address in the next field (e.g., a post office box or business address).

Remember: the correspondence address you provide will receive official letters from ZUS, the tax office, and other institutions.

Step 3: Choose Your PKD Codes (The Most Critical Decision)

The primary PKD code defines your predominant business activity. It appears in the CEIDG registry and determines your lump-sum tax rate (if you choose ryczałt) and your reporting obligations. You can add up to nine additional PKD codes.

Here is a table of commonly chosen PKD codes and their 2025 lump-sum tax rates for quick reference:

Always verify your code using the official GUS PKD search at stat.gov.pl/klasyfikacje/pkd_2007/. An incorrect PKD code can lead to a rejected application or later complications with tax authorities.

Step 4: Set Start Date and Choose Tax Form

Enter the exact date you plan to start your business (e.g., 2025-06-01). The system will not accept a date before today. Then select your tax form from the dropdown menu. For beginners, two safe options are:

• General tax scale (12% up to 120,000 PLN annual income, 32% above) – best if you have significant deductible business costs.
• Lump-sum tax (ryczałt) – simpler accounting, but rates depend on your PKD code.

Important: You cannot change your tax form mid‑year without tax office permission. If you later decide to switch, you must file a separate declaration (PIT-28 or PIT-36).

Step 5: Consent to Data Publication and Correspondence Address

CEIDG publishes your name, surname, PKD code, business address, and registration date in a public database. To keep your home address hidden, enter a different correspondence address. This field is optional, but strongly recommended for privacy. All official letters from ZUS, the tax office, and other institutions will be sent to this address.

Step 6: Sign and Submit

Before clicking the final button, review the summary page. The system automatically checks for errors – missing fields are highlighted with a red border and a message appears at the top. After correcting any mistakes, sign the application by clicking “Podpisz i wyślij” (Sign and Send). You will receive a confirmation email or ePUAP message within minutes. Save the reference number – you will need it for any future updates.

Your Post‑Registration Checklist (What to Do Next)

Once your CEIDG-1 form is accepted, you automatically receive a NIP (tax identification number) and REGON (statistical number) if you did not already have them. Within 7 days you must:

• Register with ZUS using form ZUS ZUA (or ZUS ZWUA if you already have social insurance) – the CEIDG form automatically forwards your data to ZUS, but for certain activities (e.g., partnerships) a separate application is required.
• Open a dedicated business bank account – mandatory if you expect cashless transactions exceeding 20,000 PLN per transaction (mandatory split payment from 2025).
• Check your VAT reporting obligations – if you are an active VAT taxpayer, you must submit JPK_VAT monthly or quarterly.

If you plan to hire employees, register them with ZUS within 7 days of the employment start date. For a complete list of post-registration obligations, visit the official CEIDG Information Point.

Common Mistakes and How to Avoid Them

• Wrong PKD code – double‑check using the GUS search tool. Avoid selecting a code that requires a permit (e.g., medical services need additional licenses).
• Outdated correspondence address – if you change your address after registration, file a CEIDG-2 update within 7 days.
• Missing consents – the form includes data processing consents; all must be ticked before submission.
• Choosing a tax form without advice – lump-sum tax can be disadvantageous if you have high deductible costs. Use a tax calculator at Podatki.gov.pl or consult a tax advisor.

Final Practical Checks Before You Click “Send”

The CEIDG-1 form is designed to be simple, but the choices you make – especially PKD codes and tax form – have long‑term consequences. If you are unsure about any field, call the CEIDG helpline at +48 22 432 74 74 (weekdays 8:00–16:00) or visit a local CEIDG information point (list at gov.pl/web/ceidg). Rely on official sources, not blog posts alone, to keep your registration smooth and your business compliant from day one.
