Below you will find a detailed description of the step-by-step registration of a sole proprietorship, which will help you successfully start your own sole proprietorship.

1. Determining the Legal Form
Before starting the registration process, decide which legal form of conducting business suits your needs best. . In the case of a sole proprietorship, two forms of running are popular: a lump-sum taxed business or a business taxed under general rules.
They differ in the basis of taxation, method of cost accounting, tax procedures, and flexibility.
The basis of a lump-sum taxed business is determined based on a specified percentage rate applied to the revenues generated from the business activity. The entrepreneur pays a fixed amount of tax regardless of the actual costs incurred in running the sole proprietorship. There are professions for which this form of taxation is very advantageous; however, it is not suitable for everyone.
In the lump-sum form, you do not have to prove the costs incurred to reduce the tax base. Due to its formula, lump-sum taxation is usually simpler in terms of tax procedures, and lump-sum entrepreneurs have less complicated reporting obligations. The biggest advantage of this legal form is its independence from the level of costs, especially if your costs are really low, because the tax is fixed and easy to predict.
In the case of taxation under under general rules, , the tax base is determined based on the difference between revenues and costs of obtaining revenues. The entrepreneur pays tax on profit, which is calculated based on a detailed financial analysis done every month. This is a good form for companies that want to invest in their development while employing staff.
An entrepreneur taxed under general rules is obliged to prove and document all costs incurred in connection with the business activity, which entails more extensive financial documentation. Only costs of obtaining revenues are taken into account when calculating the tax.
The advantage of taxation under general rules may be a more fair settlement, as the tax is directly linked to the actual costs of conducting business.
