Who a Sole Proprietorship Suits and How to Register It

A sole proprietorship is convenient for a single owner who needs a simple operating form without creating a separate legal entity. The entrepreneur enters into contracts personally, receives income and is responsible for their obligations. An LLC is more often suitable for a business with several owners, an investor or a separate corporate structure.

Automatic registration of a sole proprietorship through Diia is free of charge. The service states that completing the application takes about 10 minutes and automatic registration up to one minute. The entrepreneur signs in, completes the application, selects the general or simplified tax regime and signs the application electronically.

The entrepreneur also selects KVED codes based on the actual goods and services. The main code reflects the principal source of income, while additional codes cover other planned activities. A KVED code describes the type of activity, while the tax rules separately determine the single-tax group and conditions for working with particular customers.

For Groups 1, 2 and 3 of the simplified system, the rules differ by activity, customer type, employees and income limit. The entrepreneur selects a group according to how sales will actually be made, who will be invoiced and what turnover is expected. An unsuitable group may prevent the required contract from being entered into or create unnecessary tax costs.

For an entrepreneur, it is important to separate business money from personal expenditure in day-to-day records. A business account simplifies control of income, payment of taxes and explanation of transactions to the bank. The owner sees the actual cash flow of the business and more quickly understands how much remains after taxes and current costs.

Taxes, Account and Sales Documents

The entrepreneur selects the general or simplified system by reference to the activity, customers, turnover and costs. For the single tax, the group, permitted activities, limits and rules for working with counterparties are important. Under the general system, documented expenditure and income records are more significant.

For cashless settlements, the entrepreneur opens a business account. The bank sees the KVED codes, expected turnover, customers and the nature of payments, so this information should correspond with actual operations. If the entrepreneur accepts card payments or cash, they separately determine whether an RRO or PRRO is required under the rules applicable to that type of settlement.

The first customer relationship is documented by an agreement, public offer or another document appropriate to the type of sale. The entrepreneur issues an invoice, confirms performance of the service or transfer of the goods and retains primary documents. This gives the accountant a basis for correct recording of income.

If the entrepreneur hires employees, they become an employer and must comply with the requirements for employment documentation, payroll, taxes and reporting. Costs are simpler for a person working alone. The future team is therefore another factor to consider when choosing between sole proprietor and LLC.

The entrepreneur considers VAT separately from the single-tax group. For work with large VAT-paying customers, registration may be commercially beneficial; for consumer sales, it often changes pricing and accounting. The decision depends on turnover, cost structure and whether customers expect a VAT invoice.

If the entrepreneur works with foreign customers, the contract currency, method of receiving funds and banking documents are determined in advance. For exports of services, the invoice, agreement or electronic arrangement should correspond with the actual service and payment.

In 2026, the maximum monthly single-tax rate for Group I sole proprietors is UAH 332.80 and for Group II UAH 1,729.40. The military levy for Groups I, II and IV is UAH 864.70 per month. Group III uses a single-tax rate of 5% of income, or 3% of income with VAT, and the military levy is 1% of income.

When It Is Advantageous to Move from Sole Proprietor to LLC

A sole proprietorship works well while the business belongs to one person and the owner is comfortable being personally responsible under contracts. When a partner, investor, material assets, a large team or a need to sell part of the business appears, the owner compares sole proprietor with LLC. In an LLC, corporate rights and assets are separate from the participant personally.

Growth in turnover also changes the tax calculation. The entrepreneur compares taxes, accounting costs, VAT, employee payroll and banking conditions. Sometimes a sole proprietorship remains advantageous; in other cases, an LLC gives the owner a better structure for new customers and contracts.

UBC can register a sole proprietorship, help select KVED codes and the tax regime, and explain which documents are required for the first sale. The client receives an operating form suited to the business and can move directly to contracts, the account and receipt of income.

The entrepreneur can change KVED codes and the tax regime within the established deadlines and rules. This makes it possible to start with a simpler model and later add new goods or services or move to another tax regime. The owner only needs to make the change before starting activity that requires different tax conditions.

If a sole proprietor sells through a website, marketplace or social media, the entrepreneur separately documents sales terms, returns, payment and delivery. For services, the scope of work, term, price and acceptance of the result are important. These documents support normal customer relationships once the business has started.

The entrepreneur also determines who will keep the records: personally or an accountant. For a small turnover, simple daily control of income is sufficient; as sales grow, it becomes advantageous for the owner to delegate accounting to a specialist and regularly see the amount of taxes and net income.
