Highlight

Fiscalization was first introduced in Poland in 1993. Four types of devices are used for fiscalization: fiscal printers, electronic cash registers (all-in-one devices), online cash registers or online printers with integrated online checkout, and virtual cash registers for specific groups of taxpayers. The country uses the zloty (PLN) as its official currency.

Poland

In 2019, Poland introduced a new type of fiscalization that implies that fiscally relevant transactions have to be sent to the fiscal authority through the Internet with the use of online cash registers or online printers. Despite the fact that the new fiscal law was supposed to go into effect in October 2018, devices became available in January 2019, but most of them switched to online cash register/online printers.

Type of fiscalization: Hardware

Poland’s fiscalization system allows the use of four types of fiscal devices—fiscal printers, electronic cash registers, online cash registers, and virtual cash registers—with no additional certification required for POS applications. All businesses selling goods or services must issue a fiscal receipt for every transaction, regardless of payment method or customer request, and must complete registration, tax ID acquisition, device purchase, and fiscalization before starting sales. The transition to online cash registers was implemented in three mandatory phases between January 2020 and July 2021, targeting specific industries first, while other sectors remain exempt for now.

A fiscal transaction counter sounds simple—until it meets the reality of modern retail. POS systems often count much more than sales, creating gaps that can become a serious problem for tax authorities. Add cloud POS, e-commerce, offline operation, retries and multiple checkout channels, and a simple sequence of numbers quickly becomes a complex compliance architecture challenge.
