Voluntary VAT Payer – When Is It Worth It and How to Register?

Voluntary VAT payer is an entrepreneur who decides to register for value-added tax despite the fact that the law does not require them to do so. This step can bring a competitive advantage, a higher VAT deduction, and a more professional image. However, it also brings the obligation to file tax returns, keep detailed records, and undergo stricter scrutiny by the tax office. By using tax advisory, you can verify whether registration is truly beneficial for your company.

What Does It Mean to Be a Voluntary VAT Payer and Who Is It Intended For?

A voluntary VAT payer is a business entity registered under § 4 of the VAT Act, which decided to take this step on its own. Registration grants the right to apply an input VAT deduction, thereby reducing the effective price of purchased goods and services. It is intended for sole traders, small s.r.o. companies, and starting entrepreneurs who want to appear more reputable or trade exclusively with other VAT payers. The difference compared to mandatory registration lies in the voluntariness of the decision and the possibility of timing.

How Does a Voluntary VAT Payer Differ from a Mandatory Payer?

A mandatory VAT payer must register by law upon reaching a turnover of €50,000 for the previous calendar year or upon instantly exceeding a turnover of €62,500 in the current year. A voluntary VAT payer submits an application at any time they deem appropriate – i.e., before reaching these limits. However, both groups have completely identical rights and obligations after successful registration.

When Does It Make Sense to Consider Voluntary Registration?

If your input costs regularly exceed 30% of your total expenses and you purchase from VAT payers, the deduction can significantly improve your cash flow. It also makes sense when exporting goods or services abroad, where a VAT deduction is almost always advantageous. However, for supplies to end consumers (B2C), your price with VAT for the customer will increase by the standard rate, which may disadvantage you. In such a case, it is essential to consider an accounting consultation so that you do not lose money on pricing.

What Are the Legal Conditions for Voluntary VAT Registration?

The conditions are regulated by § 4 para. 1 of the VAT Act: it is assumed that the entrepreneur performs an economic activity (or demonstrably prepares for it) and has their registered office, place of business, or fixed establishment in Slovakia. A starting entrepreneur who has not yet achieved any turnover can also register. However, the tax administrator will thoroughly scrutinize the reality of your business plan to prevent fraud. We recommend consulting all conditions with a tax advisor, as insufficient proof of activity leads to the rejection of the application.

Does the Tax Office Require a Financial Guarantee?

No. The flat-rate obligation to provide a financial guarantee for voluntary registration was legally abolished; the tax office will not request money from you in advance. Instead, however, you must demonstrate stability and real performance of activity – the office often requests a business plan, existing contracts with suppliers or customers, invoices, or performs a personal inspection of the premises.

How Does the Registration of a Voluntary VAT Payer Work Step-by-Step?

Registration begins with submitting an electronic application to the tax office, using the general registration form available on the portal of the Financial Administration of the Slovak Republic. The verification process by the office usually takes several weeks. After approval, you will receive a decision and an assigned VAT ID, which brings the obligation to keep detailed VAT records.

What Documents Must an Entrepreneur Submit to the Tax Office?

It is ideal to attach documents directly to the electronic application that prove you are actually doing business or actively launching the business, particularly:

• Issued and received advance invoices or orders
• Agreements on future contracts with clients
• Lease agreement for an office, headquarters, or warehouse
• Business plan or a detailed description of activities and investments All documents must be submitted electronically via the FS portal and in the Slovak language.

Where to Find the Form and How to Submit It?

If you want to become a voluntary VAT payer, you fill out the form “Application for registration…” directly in your personal internet zone on the portal of the Financial Administration of the Slovak Republic. The form is submitted exclusively electronically, and after filling in the identification data, you check the appropriate checkbox for voluntary registration under § 4.

How Much Do You Pay as a Voluntary VAT Payer and What Are the Obligations?

A voluntary VAT payer applies a standard tax rate of 23%, or reduced rates of 19% or 5%. The resulting tax liability is calculated as the difference between output VAT from your sales and input VAT from your purchases. If the input tax is higher, an excess deduction arises, which the state returns. In addition to the tax itself, regular administration and filing of reports await you, meaning that the costs of accounting usually increase slightly.

How Often Should the Tax Return and Control Statement Be Filed?

A newly registered VAT payer is by law a monthly payer for at least the first 12 months. Both the tax return and the control statement are always submitted together, electronically by the 25th day of the following month. After one year has passed, you can switch to a quarterly tax period if your turnover for the previous 12 months did not exceed €100,000.

What Advantages Do AI Automation and Document Digitization Bring?

Modern trends are also impacting the tax agenda, as AI document reading can automatically extract data from PDF invoices, match them with accounting items, and instantly prepare supporting documents for the VAT return. This radically reduces manual data entry errors and saves time, while smart accounting software can detect logical inconsistencies in the control statement before it is sent to the Financial Administration, protecting you from unnecessary fines.

When Is Voluntary VAT Registration Not Worth It and What Are the Risks?

Registration is generally not worth it if you supply services or goods predominantly to non-VAT payers and end consumers (B2C). Your price for them would automatically increase by 23%, which could cause you to lose competitiveness in the market. Another risk is the increased attention from the tax office – if you consistently report only excess deductions without real sales, you risk opening a tax audit.

FAQ – Frequently Asked Questions About Voluntary VAT Payers

Can I Become a Voluntary VAT Payer Even as a Non-Entrepreneur?

No. Voluntary registration is strictly tied to the performance of economic activity, meaning a regular natural person (e.g., an employee) cannot become a VAT payer. An exception may be renting real estate if it shows signs of continuous economic activity and the lessor has an assigned tax ID (DIČ).

How Long Does It Take for the State to Return VAT from Purchases?

The standard period for returning an excess deduction is 30 days from the deadline for filing the tax return for the following tax period. However, if the tax office opens a tax audit before returning the money, the period is extended until its official completion.

Is It Possible to Cancel Voluntary VAT Registration Later?

Yes, you can apply for the cancellation of registration at the earliest after 12 months from the moment you became a payer. The application is submitted electronically, and the tax office will verify compliance with the conditions to check whether your turnover does not reach the threshold for mandatory payment.

What Is the Difference Between a Voluntary VAT Payer and a Person Registered Under § 7a?

A voluntary VAT payer under § 4 has full rights and obligations – they remit VAT from sales and deduct it from purchases. A person registered under § 7a (identified person) registers only for the purpose of receiving or providing services to/from abroad. This person is not entitled to a VAT deduction from domestic purchases and issues domestic invoices without VAT.

Do I Have to Use eKasa as a Voluntary VAT Payer?

Not automatically, as the obligation to use eKasa depends on whether you accept cash or credit card payments on-site from end customers. If you operate exclusively through issuing invoices and bank transfers as a VAT payer, you do not need eKasa.
