This checklist shows the whole path of opening a JDG: steps, documents and deadlines. You can do it yourself, but a mistake at the start later costs extra payments, interest and stress. It is simpler and usually cheaper to leave it to MK Buhgalteria: you send the documents, we do the rest.
The simple way: we open your JDG for you
- 0 zł for JDG registration with a one-year bookkeeping contract.
- We check your right to a JDG and choose the PKD codes.
- We calculate all three tax forms on your figures before you register.
- You only sign the application online, no visit to an office.
- First month of bookkeeping 30% off.
Steps
- Check your right to a JDG. For non-EU foreigners, since 5 March 2026 it depends on the type of residence document. Details in who can register a JDG after 5 March 2026. If you have no right to a JDG, a sp. z o.o. remains an option. With us: we check your right against your document before filing.
- Get a PESEL and an e-signature. Online registration needs a PESEL and a Trusted Profile (profil zaufany), bank login or qualified signature. With us: we tell you the fastest way to get what is missing.
- Choose PKD codes. They decide the ryczałt rate, the VAT obligation and whether you need a cash register. You can have several codes, one of them main. With us: we choose the codes for your activity.
- Compare the three tax forms. Ryczałt, the 12% and 32% tax scale or liniowy 19%: compare them in the tax calculator. The choice is yours, and it can only be changed from the next year. With us: we calculate all three on your figures and show the difference in złoty.
- File CEIDG-1. Your details, address, PKD codes, tax form and ZUS choice go in one application. The JDG appears in the register in 1-3 working days, NIP and REGON are assigned automatically. With us: we fill in the application, you only sign it online.
- Check ZUS. ZUS registration goes with CEIDG-1, but check the contribution code: ulga na start, preferential or full. With us: we choose the code so you do not lose a relief.
- Decide on VAT. If you need VAT, file VAT-R before the first taxable sale. A VAT payer’s business account must be on the white list. With us: we tell you whether you need VAT and file VAT-R.
- Start the books in the first month. Books started late have to be rebuilt, and that costs more. With us: we keep your JDG books from day one.
Documents you will need
If you open the JDG with us, just send photos of these documents on WhatsApp.
- Passport.
- The document that gives you the right to stay in Poland: residence card, visa, UKR status or other.
- PESEL and access to a Trusted Profile or bank login.
- Home address and business address.
- A short description of the activity to choose PKD codes.
- Expected monthly revenue and costs to compare the tax forms.
- Bank account number if you register for VAT.
Monthly deadlines
- By the 20th: ZUS contributions for the previous month to your individual ZUS account.
- By the 20th: PIT advance for the previous month, or for the quarter if you settle quarterly.
- By the 25th: JPK_V7M or JPK_V7K and VAT payment if you are a VAT payer. With services or supplies to firms in other EU countries, also VAT-UE.
With us you do not need to remember these dates: by the 15th you receive the ZUS, PIT and VAT amounts with bank details, and we file JPK and the returns.
Annual deadlines
- By 20 February: change of tax form for the year in CEIDG. If your first income in the year comes after January, the deadline is the 20th of the following month.
- 15 February to 30 April: annual return: PIT-28 on ryczałt, PIT-36 on the tax scale, PIT-36L on liniowy.
- By 20 May: annual health contribution reconciliation.
- Watch the ZUS reliefs: ulga na start lasts 6 months, preferential ZUS another 24 months. After that contributions rise. Amounts in ZUS for a JDG in 2026.
With us we prepare and file the annual return and the health contribution reconciliation, and before the year ends we recalculate the tax form on your figures.
Mistakes that cost money
- An unfavourable tax form applies for the whole year: it can only be changed from the next one.
- The wrong ZUS code: a lost relief or extra contributions.
- A missed VAT-R or a wrong PKD code: back VAT with interest.
- A missed ZUS, PIT or JPK deadline: late interest and fines.
- Books started late: rebuilding them costs more than keeping them from day one.
We check every step before filing so that a mistake does not cost you money. Questions about your affairs are included in the monthly fee, at no extra charge.
