Online fiscal cash register 2026 — who is required to have one
The obligation to use an online fiscal cash register is gradually expanding to cover more industries. In 2026, the list is the broadest in history, while the exemption threshold remains at PLN 20,000 in annual turnover from sales to individuals. Below is a comprehensive guide: who is affected, what are the deadlines, how much implementation costs, and what penalties apply for non-compliance.
Legal basis
The obligation to use fiscal cash registers stems from Article 111 of the VAT Act (Journal of Laws 2024, item 361, consolidated text). The detailed list of industries and activities subject to the unconditional recording obligation is set out in the Regulation of the Minister of Finance of November 24, 2023, on exemptions from the obligation to maintain sales records using fiscal cash registers (Journal of Laws 2023, item 2605), amended by the regulation of December 18, 2025, effective from January 1, 2026.
Online cash registers (registers with electronic copy storage and data transmission to the Central Register of Cash Registers — CRK) are the only permitted type of fiscal cash register since January 1, 2023. Old registers with paper or electronic copy storage can no longer be used — their replacement had to be completed by December 31, 2022, at the latest.
Industries required to have a cash register regardless of turnover
Regardless of turnover, a cash register is required for, among others: services provided by mechanics, hairdressers, beauticians, doctors, lawyers, sale of LPG, fuels, electronics, perfumes, tobacco, and alcohol. From 2026, the list now also includes IT repairs, pet grooming salons, and food service (excluding B2B catering).
Full list of industries and activities subject to the obligation regardless of turnover in 2026:
| Group | Example activities / PKWiU codes | Obligation since |
|---|---|---|
| Automotive | Vehicle repair, tire replacement, sale of parts (PKWiU 45.20) | 2015 |
| Personal services | Hairdressing, beauty treatments, tattoo services | 2015 |
| Healthcare | Doctors, dentists, physiotherapists | 2015 |
| Legal and advisory | Attorneys, legal counselors, notaries, tax advisors | 2015 |
| Fuels and LPG | Retail sale of fuels, LPG gas | 2015 |
| Electronics and perfumes | Computers, phones, cameras, perfumes, eau de toilette | 2015 |
| Tobacco and alcohol | Alcoholic beverages, tobacco products | 2015 |
| Food service | Food service activities (excluding B2B catering) | 2021 |
| Fitness and recreation | Gyms, fitness clubs, sports facilities | 2021 |
| IT repairs (new) | Computer, printer, smartphone servicing | 2026 |
| Pet grooming (new) | Grooming, pet hotels, dog spa salons | 2026 |
Note: If you operate in any industry listed above, even a single zloty of sales to an individual (non-business customer) triggers the obligation to have a cash register — with no turnover threshold.
PLN 20,000 exemption threshold — who qualifies
All other entrepreneurs are exempt up to PLN 20,000 in annual turnover from sales to individuals (calculated proportionally in the first year of operation). After exceeding the threshold, you have 2 months to install a cash register. B2B sales documented with a VAT invoice do not count toward the threshold.
How to calculate the proportional threshold
If you start your business during the year, the threshold is calculated proportionally to the number of days you operated in the given tax year:
Threshold = PLN 20,000 × (number of business days in the year / 365)
Practical example
Anna opened a photography studio on July 1, 2026. Her threshold for 2026 is:
PLN 20,000 × (184 / 365) = PLN 10,082
By September 30, she reached PLN 10,500 in B2C sales. The threshold was exceeded, so she has until November 30, 2026, to install an online fiscal cash register (2 months from the end of the month in which the threshold was exceeded).
What counts toward the threshold and what does not
| Counts toward the threshold | Does not count |
|---|---|
| Sale of goods to individuals (B2C) | Sales to businesses with a VAT invoice (B2B) |
| Services for individuals | Sale of fixed assets |
| Advance payments and prepayments from individuals | Intra-community supplies (WDT) |
| B2C mail-order sales (if payment is cash on delivery) | Sales paid by bank transfer, where records identify the buyer (exemption under §2(1) of the regulation) |
Step by step: implementing an online fiscal cash register
- Check whether your industry is on the mandatory list — if so, skip the threshold analysis and install a cash register immediately.
- Calculate your B2C turnover — sum up sales to individuals in the current year (proportionally if this is your first year).
- Choose a cash register — it must have type approval (a GUM decision) and a communication module for CRK transmission. Popular models: Posnet Ergo Online, Novitus Next Online, Elzab Jota Online.
- Fiscalization — a certified technician performs fiscalization (assigning a unique number) and registers the device in the CRK.
- Report the cash register to your tax office — complete the online form at podatki.gov.pl or submit a paper form to the tax office within 7 days of fiscalization.
- Apply for the PLN 700 relief — in the VAT-7/VAT-7K return for the period in which you started recording sales.
- Maintain regular technical inspections — a mandatory inspection every 2 years (Article 111(3d) of the VAT Act). Missing an inspection results in losing the relief entitlement and a penalty.
Costs and the purchase relief
An online cash register costs PLN 1,200–2,500 net + a subscription of PLN 15–30/month for CRK data transmission. The tax office reimburses 90% of the purchase cost, up to PLN 700 maximum, provided you register on time. Not having a required cash register triggers a 30% VAT penalty on undocumented sales.
Online fiscal cash register cost comparison in 2026
| Model | Net price | CRK subscription | Net relief (90%, max PLN 700) | First-year cost after relief |
|---|---|---|---|---|
| Posnet Ergo Online | PLN 1,350 | PLN 20/month | PLN 700 | PLN 890 |
| Novitus Next Online | PLN 1,600 | PLN 25/month | PLN 700 | PLN 1,200 |
| Elzab Jota Online | PLN 2,200 | PLN 15/month | PLN 700 | PLN 1,680 |
| Virtual cash register (tablet + app) | PLN 800 (license) | PLN 30/month | PLN 700 | PLN 460 |
Conditions for obtaining the PLN 700 relief
- The cash register has a valid GUM type-approval decision and a CRK transmission module.
- The taxpayer started recording sales within the required deadline (not after the deadline).
- The cash register was reported to the head of the tax office within 7 days of fiscalization.
- The relief amount is deducted in the VAT-7 return (line 52) or VAT-7K. Taxpayers exempt from VAT receive a refund to their bank account upon application (deadline: 25 days).
Virtual cash registers — new in 2026
Since February 1, 2026, a regulation permits virtual (software-based) cash registers in the following industries: food service, passenger transport, hotel services, and ticket sales. A virtual cash register is a certified application on a tablet or smartphone, connected to the CRK — it does not require a separate fiscal device. Costs are lower (approximately PLN 800 for a license + subscription), but it is only permitted in selected industries specified in the regulation.
Most common mistakes when implementing a cash register
- Installing too late — the entrepreneur waits until the last day of the deadline and cannot complete fiscalization in time. Result: 30% VAT penalty.
- No CRK transmission — the cash register must connect to the CRK at least once every 24 hours. An interruption exceeding 48 hours requires notification to the service provider and the tax office.
- Incorrect VAT rate on the receipt — e.g., applying 8% instead of 23% on beauty services. The tax office treats this as defective record-keeping.
- Missing technical inspection — if you do not complete the inspection every 2 years, you lose the relief entitlement and must return the PLN 700.
- Issuing receipts with NIP (tax identification number) above PLN 450 — a receipt with the buyer's NIP up to PLN 450 constitutes a simplified invoice. Above that amount, the customer should request a full invoice.
- No NIP on the receipt when an invoice is requested — since 2020, an invoice matching a receipt can only be issued if the receipt contained the buyer's NIP. No NIP = refusal to issue an invoice.
Penalties for not having a fiscal cash register
The consequences are severe and multi-layered:
| Type of penalty | Legal basis | Effect |
|---|---|---|
| Additional 30% VAT liability | Article 111(2) of the VAT Act | 30% of input tax on purchases — loss of the right to deduct VAT on purchases related to unrecorded sales |
| Fine (Fiscal Penal Code) | Article 62 §1 of the Fiscal Penal Code (KKS) | Fine of up to 180 daily rates (in 2026, maximum approx. PLN 5.4 million) |
| Summary fine | Article 62 §5 of the Fiscal Penal Code (KKS) | Up to PLN 7,200 (5× minimum wage / 10) |
| Loss of relief entitlement | Article 111(6) of the VAT Act | Obligation to return the PLN 700 relief + interest |
2026 deadlines — calendar

FAQ — frequently asked questions
Does selling on Allegro require a fiscal cash register?
Yes, if you sell to individuals and exceed the PLN 20,000 threshold (or operate in a mandatory industry). Exception: sales exclusively paid by bank transfer, where records allow identification of the buyer — in that case, you benefit from the exemption under §2(1) of the regulation.
Can I use a fiscal printer instead of an online cash register?
No. Since 2023, the only permitted type is an online cash register with CRK transmission. Fiscal printers that work with a computer are still considered cash registers — but they must have an online module.
What if the internet in my premises is down?
The cash register stores data in its internal memory and transmits it to the CRK once connectivity is restored. The permissible interruption is 48 hours. Beyond that, you must report the failure to your service provider and the tax office.
Does private rental require a cash register?
Private rental (outside business activity) to individuals benefits from a subject-matter exemption (§2(25) of the regulation). No cash register is required, regardless of the amount — provided that all turnover is documented with invoices or contracts containing the tenant's details.
Do I have to print a receipt if the customer wants an e-receipt?
Since September 15, 2023, a taxpayer may send an e-receipt (with the buyer's consent) — an electronic receipt is equivalent to a paper one. Condition: the cash register must support the e-receipt function, and the buyer must consent before the transaction.
What is the penalty for not having a fiscal cash register?
In addition to the 30% VAT penalty, a fine under the Fiscal Penal Code (KKS) applies — in summary proceedings up to PLN 7,200, and in court proceedings up to 180 daily rates (in 2026, the daily rate ranges from PLN 130 to PLN 43,380, so the maximum fine exceeds PLN 5 million — although such severe penalties apply only in extreme cases).
Summary
Check whether your industry is subject to the obligation without any threshold. If you are approaching PLN 20,000 in B2C sales, plan for a cash register a month in advance. Remember to report to the tax office on time and apply for the PLN 700 relief — it represents real savings on implementation costs. Regular technical inspections every 2 years and reliable CRK transmission ensure you avoid penalties and maintain your right to deduct VAT.
