Regulations in Poland govern how small businesses manage cash and how financial institutions monitor transactions. Small businesses must adhere to technical security requirements for storing and transporting money based on a threshold calculated from average monthly salaries. Currently, specific safe classes are required when cash amounts exceed 0.2 of a designated computational unit, roughly 220,000 PLN. Business owners must balance these legal requirements against theft risks and insurance coverage.

In the banking sector, institutions may request documentation regarding the source of cash deposits regardless of the transaction size. While transactions exceeding 15,000 euros must be reported to the General Inspector of Financial Information, banks also use risk assessments and Know Your Customer protocols to monitor smaller amounts. Failure to provide origin-of-funds explanations can result in refused deposits or limited account access. When assessing creditworthiness for mortgages, banks prioritize income stability, net income, employment duration, and the regularity of earnings, alongside an analysis of revenues, costs, and taxation forms.

New regulatory shifts are introducing digital mandates and adjusting cash limits. As of November 1, 2026, municipal offices will cease accepting paper applications for starting sole proprietorships, requiring applicants to use digital platforms like biznes.gov.pl or the mObywatel app. Furthermore, a legislative proposal submitted to the Sejm seeks to increase the current 15,000 PLN limit for B2B cash transactions to 25,000 PLN to account for inflation and provide greater settlement flexibility.
