1. Short answer

In 2026, a Finnish sole proprietor and other businesses must register for VAT if the business turnover exceeds €20,000 in a calendar year. The threshold is no longer €15,000, and it is not calculated as a rolling 12-month period. It is based on sales during the calendar year.

According to the Finnish Tax Administration’s current guidance, a business does not need to register for VAT if both the current and the previous calendar year’s turnover are no more than €20,000. If the threshold is exceeded, VAT liability begins from the date when the threshold is crossed.

The most important distinction is this:

The €20,000 VAT threshold applies when you invoice through your own business, such as a Finnish sole proprietorship. It is not a personal “light entrepreneur threshold” if you invoice through an invoicing service without your own Business ID.

If you invoice through an invoicing service such as Bisse.fi without your own company, you are not personally in the VAT register. The invoicing service sends the invoice as its own company and handles VAT. In that situation, the €20,000 threshold does not mean that you can invoice below the threshold without VAT. VAT is added to taxable work through the service as normal.

2. Who does the €20,000 VAT threshold apply to?

The VAT threshold applies to a business or entrepreneur selling goods or services as business activity. In practice, this includes:

• a sole proprietor
• a limited company
• a limited partnership or general partnership
• an association or other operator if it carries out VAT-taxable business activity

This article focuses on sole proprietorships, because the question often comes from light entrepreneurs who are considering moving from an invoicing service to their own Business ID.

If you have your own sole proprietorship, you are responsible for knowing whether you need to:

• monitor the €20,000 threshold
• register for VAT
• add VAT to your invoices
• file VAT returns
• pay VAT in MyTax
• deduct purchase VAT correctly

If you invoice without your own Business ID through an invoicing service, you are not acting toward the customer as a VAT-registered sole proprietor. The invoice is sent by the invoicing service company. VAT handling is therefore based on the invoicing service and the type of work being invoiced, not on your personal annual invoicing reaching or staying below €20,000.

This distinction matters because the term “light entrepreneur” is used in Finland in two different ways:

3. What does the €20,000 threshold mean in 2026?

The practical rule for 2026 is:

If a business’s turnover exceeds €20,000 in a calendar year, the business must register for VAT.

If both the current and the previous calendar year’s turnover are no more than €20,000, the business usually does not need to register for VAT on the basis of minor business activity.

The threshold rose to €20,000 at the start of 2025. At the same time, the old VAT lower-limit relief scheme was discontinued for new accounting periods. This means that in 2026 there is no longer a system where a small VAT-registered business can receive part of the VAT it has paid back as lower-limit relief.

The practical effect is clear:

• If you stay below the threshold and are not voluntarily VAT-registered, you do not add VAT to your invoices.
• If you exceed the threshold, you must register and add VAT to taxable sales from the threshold-crossing point onward.
• If you voluntarily register for VAT while still below the threshold, you add VAT to taxable sales from the start of registration.

Monitoring the threshold is the sole proprietor’s responsibility. An accountant or bookkeeping service can help, but the entrepreneur is responsible for making sure the business is in the correct register at the correct time.

4. How turnover is calculated

The €20,000 threshold is calculated from calendar-year turnover. This is an important change compared with the way many old articles describe the rule.

In 2026, you therefore look at sales during:

1 January 2026-31 December 2026

Not, for example:

• the previous 12 months on a rolling basis
• your accounting period if it differs from the calendar year
• taxable profit only
• the amount left in your bank account after expenses

Turnover means sales excluding VAT. If you are not VAT-registered, in practice you monitor the taxable value of your sales. If you are VAT-registered, VAT is not included in turnover for the threshold assessment.

According to the Finnish Tax Administration’s guidance, turnover includes, for example:

• VAT-taxable sales excluding VAT
• certain VAT-exempt sales, such as intra-Community sales and export sales
• certain financial and insurance services
• rental of real estate in certain situations

Turnover usually does not include, for example:

• sale of business fixed assets, such as a machine used in business
• some ancillary financial and insurance service sales
• most VAT-exempt sales, such as healthcare services or social welfare services

If your activity includes exempt sales or 0% VAT sales, check the threshold calculation with an accountant or the Finnish Tax Administration’s guidance. Not every invoiced euro is treated in the same way.

5. When a sole proprietor must register for VAT

A sole proprietor should register for VAT no later than when it looks likely that the €20,000 threshold will be exceeded during the current calendar year.

Do not wait until the end of the year if you already know in September that your November invoices will push turnover above the threshold. According to the Finnish Tax Administration’s guidance, a business should register for VAT in good time in advance so that it is in the register from the date the threshold is exceeded.

Example 1: the threshold is not exceeded

A sole proprietor starts service work in January 2026. Turnover in 2025 was €0 because the business did not yet exist. Sales in 2026 amount to €17,500.

The business usually does not need to register for VAT on the basis of minor business activity, because current calendar-year turnover stays below €20,000.

Example 2: the threshold is exceeded late in the year

The sole proprietorship’s turnover in 2025 was €13,000. At the start of 2026, the entrepreneur estimates that sales will remain around €18,000. In the autumn, however, a new customer appears, and 2026 turnover exceeds €20,000 on 15 October 2026.

The business must register for VAT from the date when the threshold is exceeded. The obligation to pay VAT also begins from that point.

Example 3: the threshold is exceeded by one larger invoice

A sole proprietorship is not in the VAT register. Sales for the year so far are €19,800. The next invoice is €500 excluding VAT.

This invoice exceeds the €20,000 threshold. According to the Finnish Tax Administration’s guidance, the sale that crosses the threshold is fully subject to VAT. In practice, the entrepreneur must make sure the registration and invoicing are handled correctly from this sale onward.

6. What happens when the threshold is exceeded during the year?

When the €20,000 threshold is exceeded, the sole proprietor must:

1. register for VAT from the threshold-crossing date
2. add VAT to taxable sales from that point onward
3. file VAT returns according to the chosen VAT period
4. pay VAT in MyTax
5. record sales VAT and purchase VAT correctly in bookkeeping

The useful part of the 2026 rule is that if the threshold is exceeded during the year, VAT liability does not automatically begin retroactively from the start of the year. It begins from the date the threshold is exceeded.

This is where an old memory can mislead you. Before the 2025 changes, many guides emphasized retroactive VAT liability from the start of the accounting period if the minor business threshold was exceeded. The 2026 rule is different: under the Finnish Tax Administration’s current guidance, registration is made from the threshold-crossing date, not from the start of the year, when this €20,000 minor business threshold is the issue.

This does not mean you can leave the matter until later. If you notice the threshold crossing only afterwards, you must register retroactively from the threshold-crossing date. The first VAT returns and payments may then already be late.

Pricing should take this into account in advance. If you agreed with a customer that the price is “€1,000 including everything”, adding VAT afterwards can be difficult. If the agreement says “€1,000 + applicable VAT”, the price change after VAT registration is clearer.

VAT has a direct effect on the final price especially for consumer customers. For business customers, VAT may be more neutral if the customer can deduct it in its own VAT reporting.

7. Should you register voluntarily?

A sole proprietor can voluntarily register for VAT even if turnover is no more than €20,000 per year. The condition is that the activity meets the characteristics of business activity. Occasional hobby sales may not be enough.

Voluntary registration may make sense if:

• your customers are mainly businesses entitled to deduct VAT
• you have many VAT-taxable purchases
• you are buying expensive tools, equipment or software
• you want to look established to business customers
• you expect turnover to exceed €20,000 soon

Voluntary registration may be a worse choice if:

• your customers are mainly consumers
• your costs are low
• you do not need VAT deductions
• you want to keep administration as light as possible
• invoicing is genuinely occasional

Once you are in the VAT register, you cannot choose invoice by invoice whether to add VAT. If the sale is VAT-taxable, VAT must be handled normally, even if turnover remains below €20,000.

8. What if you invoice through Bisse.fi without your own company?

This is where many people get confused.

If you invoice through an invoicing service such as Bisse.fi without your own Business ID, the €20,000 threshold is not your personal VAT exemption threshold.

As a light entrepreneur without your own Business ID, you are not personally in the VAT register. The invoicing service sends the invoice to the customer and handles VAT. That is why you cannot tell the customer: “I will not add VAT because I will invoice less than €20,000 this year.”

In practice, this means:

• VAT is added to taxable work through the invoicing service
• your personal invoicing amount does not determine the invoice’s VAT status
• you do not file VAT returns yourself for this invoicing
• you cannot deduct VAT on your own purchases in the same way as a VAT-registered sole proprietor
• the service handles invoicing and related VAT processing according to its terms

There can still be exceptions depending on the type of work. For example, certain performer fees, the construction reverse charge, or international invoicing situations can affect the VAT rate used. Even then, the issue is not that you have a personal €20,000 VAT threshold inside the invoicing service.

If, however, you have your own Business ID and use Bisse.fi or another service to help with sole proprietor bookkeeping, invoicing or document handling, the situation is different. In that case, you operate through your own business and must monitor the €20,000 threshold explained in this article.

If you are deciding which model fits you, start with this comparison: Sole proprietorship or light entrepreneurship.

9. Frequently asked questions

Is the VAT threshold €20,000 or €15,000 in 2026?

In 2026, the minor business activity threshold is €20,000 per calendar year. The €15,000 threshold is old information.

Is the threshold calculated over 12 months or by calendar year?

It is calculated by calendar year. In 2026, the review period is 1 January 2026-31 December 2026.

If my sole proprietorship’s sales stay below €20,000, can I invoice without VAT?

If you are not in the VAT register and your activity does not otherwise require registration, you do not add VAT to invoices. You also cannot deduct purchase VAT on a VAT return.

If I invoice through Bisse.fi without my own company and earn less than €20,000, can I leave VAT out?

Not because of this threshold. When invoicing through an invoicing service without your own Business ID, the €20,000 threshold is not your personal VAT exemption threshold. VAT is added to taxable work through the invoicing service.

What if the threshold is exceeded by one invoice?

The sale that crosses the threshold is fully subject to VAT. That is why you should monitor turnover before sending an invoice that takes the year’s sales over €20,000.

Can I register for VAT voluntarily?

Yes, if your activity meets the characteristics of business activity. This can be sensible especially when your customers are businesses and you have many VAT-taxable purchases.

Has the VAT lower-limit relief scheme been abolished?

Yes. The VAT lower-limit relief scheme is not available for accounting periods starting on or after 1 January 2025. In 2026, the relevant questions for a small business are therefore the €20,000 registration threshold and possible voluntary registration, not lower-limit relief.

10. Checklist for sole proprietors

If you invoice through your own sole proprietorship in 2026, go through these points:

1. Check whether 2025 turnover was above or below €20,000.
2. Make a realistic estimate of 2026 turnover.
3. Track sales by calendar year, not only by accounting period or bank account balance.
4. Decide whether voluntary VAT registration makes sense before the threshold is crossed.
5. If the threshold is getting close, sort out registration before crossing it.
6. In new customer agreements, use wording such as “price + VAT” if crossing the threshold is possible.
7. Once registered, add VAT to taxable sales and start filing VAT returns.
8. Keep purchase invoices and receipts so you can deduct VAT correctly.
9. Do not apply the €20,000 threshold to invoicing-service work done without your own Business ID.
10. Ask an accountant or service provider for help before the first invoice that crosses the threshold is sent.

11. Summary

In 2026, the VAT threshold for a Finnish sole proprietor is effectively €20,000 per calendar year. If both the current and previous calendar year’s turnover are no more than that, the business usually does not need to register for VAT on the basis of minor business activity. If the threshold is exceeded, registration and the obligation to pay VAT begin from the threshold-crossing date.

This rule applies to your own business activity. If you invoice without your own Business ID through an invoicing service such as Bisse.fi, the €20,000 threshold does not give you the right to leave VAT out of taxable invoices. The invoicing service handles the invoice and VAT processing as its own company.

If you are just starting out, the practical choice is this: an invoicing service makes the first invoices lighter, while your own sole proprietorship gives you more responsibility and also more opportunities, such as VAT deductions. When turnover starts approaching €20,000 or purchases become significant, it is worth reviewing the sole proprietorship and VAT registration question carefully.

Sign up at Bisse.fi if you want to invoice without your own company. If you already operate as a sole proprietor, read also the VAT guide, sole proprietor taxation, and Sole proprietorship or light entrepreneurship.
