Tax regime and accounting for sole proprietors in Poland, choice of tax form, cash register, and reporting

At the registration stage, it is important to immediately determine how the enterprise's income will be taxed. Several options are available for individual activities: general rules for the scale, flat tax и market (ryczałt). The choice depends on the planned turnover, expense structure, and specifics of services. For example, with high documented expenses, the general system is more beneficial, while a freelancer with low expenses may find ryczałt suitable. It is also worth considering the VAT issue: it is not always advantageous to remain «without VAT» if clients are mainly VAT-paying companies. For convenient comparison of options, it makes sense to calculate several income and expense scenarios in advance, at least for the first year of activity.

Form Features Who it suits
General scale Progressive rate, expense accounting For beginners with variable income
Flat tax Fixed rate, detailed accounting Stable income and high expenses
Lump sum Rate based on the type of services, without expenses Freelancing and online services

In practice, the entrepreneur chooses between self-accounting and outsourcing accounting functions to an external specialist or firm. In any case, a clear document flow system should be established:

  • timely issuance of invoices and contracts, storage of primary documents;
  • regular submission of declarations on income and, if necessary, on VAT;
  • control of ZUS contributions and reserving funds for tax payments;
  • archiving of reporting in accordance with Polish requirements.

Optimization begins with analyzing which model is more profitable given the projected turnover and expenses.
