Frequently Asked Questions

Simplified accounting can be used by individuals running a business, as well as partners in civil, general, and professional partnerships, provided they have not exceeded the revenue limit specified by regulations (currently 2 million euros annually). The form of settlement also depends on the type of business and the chosen form of taxation.

KPiR (Revenue and Expense Ledger) allows for settlements based on actual incurred costs and revenues. With the lump-sum tax on registered revenues, costs are not taken into account – tax is paid on revenue at a flat rate, depending on the type of business.

Typically, these include sales invoices, cost invoices, bank statements, cash reports, contracts, and employment-related documents (if applicable). Documents can be sent electronically or delivered in person – depending on arrangements.

No – tax liability always rests with the entrepreneur. However, by choosing an experienced accounting firm, you minimize the risk of errors and can count on professional support in case of audits or inquiries from authorities.

Yes! We serve clients from all over Poland and provide full online accounting capabilities – remote document submission, email and phone contact, e-settlements, and electronic signatures. Conveniently and without leaving your home.
