Invoices without a business registration – legal and tax aspects

Invoices issued without a business name are an issue that has been of interest to freelancers and those considering taking their first steps into self-employment for many years. The growing popularity of flexible ways of earning a living and the rapid expansion of the remote services market mean that more and more people are looking for solutions that allow them to legally document their sales – without having to register a business. In this article, I present a detailed analysis of the available options, the legal framework and the practical implications of issuing invoices and bills by individuals who do not run a business, taking into account current trends and modern platforms supporting freelancers.

Invoices without a business – definitions and legal framework

Traditionally, an invoice is an accounting document issued by a VAT-registered taxpayer in connection with the sale of goods or services. However, a natural person who does not run a business and is not a VAT-registered taxpayer cannot issue VAT invoices independently. This follows directly from Section 106b(1) of the Goods and Services Tax Act, where this right is granted exclusively to entities with the status of active VAT taxpayers. In practice, for individuals who do not run a business, the alternative is a receipt or – in certain cases – using the services of companies with legal personality, which enable an invoice to be issued on behalf of the freelancer.

Business activity versus unregistered activity

Polish law provides for two basic statuses for persons undertaking gainful activity:

• Business activity – subject to compulsory registration (CEIDG or KRS), full accounting and tax returns, and social security contributions.
• Unregistered business activity – allows you to earn money without registering a company, but with income limited to 75 per cent of the minimum monthly wage (in 2024 – PLN 3,499.50 gross per month).

Unregistered business activity is a solution intended primarily for people who wish to test their business ideas without investing straight away in a full business infrastructure. The conditions are that the person must not have carried out any business activity in the last 5 years and must keep simplified records of income.

Issuing sales documents by a person without a business

Under current regulations, a natural person not carrying on a business is not authorised to issue VAT invoices. However, they may issue a receipt, which serves as an equivalent confirmation of a sale or the provision of a service. Article 87(1) of the Tax Ordinance specifies that taxpayers carrying out business activities are obliged to issue a receipt at the purchaser’s request. However, the definition of business activity in the Tax Ordinance is broad and also covers certain activities carried out under civil law contracts.

Receipt – required details and deadlines

A receipt issued by a natural person should contain the following details:

• The full name (or business name) and address of the seller and the purchaser (the service provider and the service recipient)
• Date of issue and serial number of the invoice
• Specification of the type, quantity and unit price of the goods or services
• The total amount due (in figures and words)

The deadline for issuing the invoice depends on when the customer makes the request:

1. If the request was made before the service was provided – the invoice must be issued within 7 days of the service being provided or the goods being delivered
2. If the request was made after the service was provided – the invoice must be issued within 7 days of the date the request was made

Restrictions and tax implications

The mere fact of issuing an invoice does not exempt the issuer from the obligation to account for income tax on the revenue earned. Revenue derived from unregistered business activities must be declared in the annual PIT return, using the appropriate sections (e.g. PIT-36). The absence of an obligation to pay social security contributions (ZUS) is a significant advantage here, although it also means a lack of entitlement to social security benefits.

A VAT invoice without a business name – is this possible?

Under the Polish tax system, a VAT invoice may only be issued by an entity that is a VAT-registered trader, i.e. a natural person carrying out business activities within the meaning of the VAT Act. However, there are arrangements that allow individuals without a business to use VAT invoices – through intermediaries with legal personality.

Business incubators

Modern platforms, such as firmadlakazdego.pl, are revolutionising the freelance services market. They enable even those without a business to issue VAT invoices. The operating model is based on intermediation: the freelancer carries out the assignment, and the platform – as a business entity – issues a VAT invoice to the client, signs a civil law contract with the contractor (a contract for services or a contract for specific work), and then pays the remuneration after deducting taxes and commission.

This means the freelancer does not have to worry about bookkeeping, paying social security contributions or registering a business. This solution works particularly well for people testing the market or working on a seasonal basis.

Terms and conditions for using intermediary platforms

To use the services of such platforms, you must:

• Create an account and complete the verification process
• Submit the details of the assignment and the client’s information
• Accept the terms of the civil law contract
• Wait for the invoice to be issued and the payment to be settled

Remuneration is paid after deduction of income tax (PIT) and any health or social security contributions (depending on the type of contract and the contractor’s individual circumstances).

Comparison – receipt, invoice, unregistered business and intermediary platforms

Model	Ability to issue a VAT invoice	Tax obligations	Social security contributions	Revenue limit
Business activity	Yes	Full PIT/VAT settlement	Mandatory	None
Unregistered business activity	No	Annual PIT return	None	75% of the national minimum wage
Invoice from a private individual	No	Annual PIT return	None	None, but there is a risk of it being classified as a business activity
Business incubator	Yes (the platform issues it)	Settlements handled by the platform	None	None

Invoice to a natural person – details, deadlines, practice

It is worth clarifying that an invoice issued to a natural person (i.e. a purchaser who is not a business) does not require a tax identification number (NIP) or personal identification number (PESEL) – the first name, surname and residential address are sufficient. The deadline for issuing an invoice to a natural person corresponds to the standard statutory requirements: by the 15th day of the month following the provision of the service, or within 15 days of the request being made, if this occurred later.

With the implementation of the National e-Invoice System (KSeF), from 2024 it will be mandatory for businesses to use the government platform for issuing e-invoices. Intermediary platforms, such as the business incubator firmadlakazdego.pl, are already prepared to handle settlements in accordance with KSeF.

Practical implications and challenges

The choice of how to invoice for services without registering a business depends on several factors: expected revenue, the type of clients (private individuals or businesses), the frequency of service provision, and one’s willingness to take on tax risks. Unregistered business activity, whilst convenient, is mainly suitable for small, occasional jobs. In the case of regular cooperation with businesses or if revenue limits are exceeded, intermediary platforms or registering a business prove to be more advantageous.

A significant limitation of unregistered business activity is the inability to issue VAT invoices, which can be a barrier to working with corporate clients. Furthermore, rising revenue may lead the tax authorities to deem the activity to be carried out in an organised and continuous manner – which results in the obligation to register the business retrospectively and potential financial consequences.

In the case of intermediary platforms, a portion of the remuneration is deducted as commission; however, this is offset by comprehensive administrative support and tax security. It is also worth considering whether the specific nature of the work carried out requires the registration of special licences or permits (e.g. in the medical or transport sectors).

Conclusions and recommendations for freelancers

• If you are starting out and do not exceed the income threshold, consider operating as a self-employed person without formal registration – simplified paperwork and no need to pay social security contributions are real benefits.
• When working with business clients or generating higher income, use intermediary platforms that will issue a VAT invoice on your behalf and handle your tax returns.
• Keep an eye on your income limits and the scope of services you provide – exceeding the threshold or providing services on a regular basis may mean you are obliged to register your business.
• Keep an eye on legislative changes, particularly regarding e-invoicing (KSeF) and VAT taxpayer status.
• Adapt your billing model to your own needs and the specifics of the market, using the modern tools available to freelancers.

In summary, the ability to issue an invoice without a business depends on your chosen income stream and the nature of your collaboration with clients. Modern intermediary platforms open up the market to freelancers without a business, minimising tax risks and administrative burdens. Regardless of the method chosen, accurate documentation of income and awareness of current regulations remain key to legal and tax compliance.
