Small Business VAT Scheme (KOR) Explained: Should You Opt for VAT Exemption?

January 10, 202618 min readBy ZZP Pulse Team

The Kleineondernemersregeling (KOR) is a voluntary VAT exemption scheme for Dutch entrepreneurs with annual turnover of €20,000 or less. Since January 2025, the rules are more flexible: no more mandatory 3-year participation! This guide helps you decide whether the KOR is right for your situation.

In this guide we walk you through everything you need to know: the eligibility rules, the advantages and pitfalls, practical calculation examples for B2B and B2C, and the important 2025 rule changes that make the KOR more flexible than ever.

Key Takeaway
Key takeaway: Under the KOR, you don't charge VAT and don't file quarterly VAT returns, but you also cannot reclaim input VAT on business expenses. This trade-off makes KOR ideal for low-expense businesses selling to consumers, but often disadvantageous for B2B freelancers. Not sure how VAT works? Read our VAT questions answered guide first.

1. What is the KOR?

The Kleineondernemersregeling (KOR), or Small Business VAT Scheme, is a tax regulation administered by the Dutch Tax Authority (Belastingdienst) that provides VAT exemption for small entrepreneurs. If your annual turnover stays at or below €20,000, you can opt into this voluntary scheme. Under KOR, you are exempt from filing VAT returns.

Who can use the KOR?

  • Sole proprietors (eenmanszaken / ZZP'ers)
  • Partnerships (VOF, maatschap)
  • Legal entities (BV, stichting, vereniging)

2. Eligibility Requirements

To participate in the KOR, you must meet the following conditions:

RequirementDetails
Business locationYour business must be established in the Netherlands
VAT registrationYou must be registered as a VAT entrepreneur (btw-ondernemer)
Turnover limitMaximum €20,000 per calendar year (current and previous year)
Calculation basisRevenue excluding VAT; includes sales normally subject to VAT

What counts toward the €20,000?

Included: All products and services normally subject to VAT, letting/renting buildings, financial services, insurance services.

Excluded: Certain VAT-exempt services like medical services, sports lessons, and journalistic work.

3. How the KOR Works in Practice

Once registered for the KOR, the following applies:

AspectUnder KOR
Charging VATNot allowed—prices are VAT-exempt
VAT returnsNot required (except incidental situations)
Input VAT recoveryNot possible—you cannot reclaim VAT on purchases
InvoicesNot mandatory, but recommended
Record keepingStill required—keep purchase invoices

Important: KOR applies to ALL activities

If you have multiple business activities (subnummers), the KOR applies to all of them. You cannot selectively apply KOR to some activities and regular VAT to others.

Understanding the trade-offs is key to making the right KOR decision.

4. Advantages of the KOR

Less administration

No quarterly VAT returns, simpler bookkeeping, no VAT calculations on sales.

Save hours!

Competitive for B2C

Private clients can't reclaim VAT—your lower prices are a real advantage.

Ideal for consumers

Higher margin potential

Keep what would otherwise be VAT payable. Same price = more profit.

Maximize earnings

Flexible since 2025

No more 3-year lock-in! You can opt out at any time.

5. Disadvantages of the KOR

No input VAT deduction

The biggest drawback: you cannot reclaim VAT on ANY business expenses, including:

  • Laptops, equipment, furniture
  • Professional tools and machinery
  • Business travel and fuel
  • Software subscriptions

Less attractive for B2B

Business clients can deduct VAT anyway, so:

  • Your VAT-free price offers them no advantage
  • Your costs are higher (no VAT recovery)
  • You effectively earn less per project

Other important drawbacks

  • VAT revision: May need to repay VAT on past investments when joining KOR (see section 10)
  • Incidental VAT returns: Still required for certain EU transactions (reverse charge, EU acquisitions)
  • Exclusion period: After leaving KOR, cannot rejoin until end of next calendar year

6. Practical Calculation Examples

Example 1: Selling to Business Clients (B2B)

Scenario: Web designer selling services to businesses

Without KOR

Rekenvoorbeeld

Invoice€100 + €21 VAT = €121
Expenses€10 + €2.10 VAT = €12.10
VAT to pay€21 - €2.10 = €18.90
Net result€100 - €10 = €90

With KOR

Rekenvoorbeeld

Invoice (no VAT)€100
Expenses (VAT not recoverable)€12.10
VAT to pay€0
Net result€100 - €12.10 = €87.90
B2B conclusion: KOR results in €2.10 LESS profit because input VAT cannot be recovered, while the client would have deducted VAT anyway.

Example 2: Selling to Private Consumers (B2C)

Scenario: Hairdresser or beautician with private clients. You can choose two strategies:

Strategy A: Lower prices

Charge €100 instead of €121—more competitive!

  • Client pays: €100 (was €121)
  • Your expenses: €12.10
  • Profit: €87.90

Strategy B: Same prices

Keep charging €121—but keep the full amount!

  • Client pays: €121
  • Your expenses: €12.10
  • Profit: €108.90
B2C conclusion: For private clients, KOR can either make you more competitive (lower prices) or MORE profitable (same prices, higher margin).

Example 3: Starting ZZP'er with Large Investment

Scenario: Photographer buying €5,000 camera equipment in year 1

Rekenvoorbeeld

Equipment price€5,000 + €1,050 VAT
VAT recovered€1,050
Actual cost (without KOR)€5,000

Rekenvoorbeeld

Equipment price€5,000 + €1,050 VAT
VAT recovered€0 (KOR)
Actual cost (with KOR)€6,050
Conclusion: Starting ZZP'ers with significant investments should AVOID the KOR until the investment phase is complete. You lose €1,050 in VAT recovery on this purchase alone!

7. Who Should Use the KOR?

KOR is typically beneficial for:

8. Who Should Avoid the KOR?

Avoid KOR if you are:

9. Invoice Requirements Under KOR

Under KOR, you are not required to issue invoices for VAT purposes. However, many business clients will request an invoice for their own administration.

If you issue invoices, include:

  • Your business name and address
  • Client's name and address
  • Invoice date and number
  • Description of goods/services
  • Amount (without VAT breakdown)

Add one of these statements:

  • "Vrijgesteld van btw wegens KOR"
  • "Factuur vrijgesteld van OB o.g.v. artikel 25 Wet OB"

One common mistake to be aware of when preparing your invoices under the KOR:

Never put "0% BTW" on your invoice—this suggests a different exemption type and can cause confusion or issues with the tax authority.

10. How to Apply for the KOR

1Check Eligibility

Use the Belastingdienst's KOR tool to verify you qualify: turnover under €20,000, registered as VAT entrepreneur, established in NL.

2Apply Online

Register via Mijn Belastingdienst Zakelijk. Find the form "Melding omzetbelasting kleineondernemersregeling" and complete it.

3Timing

Submit at least 4 weeks before the start of the quarter. KOR takes effect from the first day of the next quarter. Wait for written confirmation before treating sales as VAT-exempt.

For new entrepreneurs:

You can only apply for KOR after receiving your VAT number (omzetbelastingnummer) from the Belastingdienst. Until then, file regular VAT returns.

11. Exceeding the €20,000 Threshold

What happens if you exceed €20,000 during the year?

Immediate consequences:

  • Immediate VAT obligation: From the sale that pushes you over €20,000, you must charge VAT
  • Mandatory deregistration: You must immediately deregister from KOR
  • Previous sales unaffected: Sales before exceeding remain VAT-free

Rejoining the KOR

After deregistration, you can rejoin only after: the remainder of the current calendar year AND the entire next calendar year. If your turnover fluctuates around €20,000, the KOR may not be suitable.

12. VAT Revision Rules (BTW Herziening)

This is often overlooked: joining the KOR can trigger VAT repayment obligations on past investments.

Asset TypeRevision Period
Movable goods (equipment, vehicles)5 years
Immovable property (buildings, land)10 years

To make this concrete, let's look at how the revision calculation works in practice with a real example.

Calculation Example

Situation: You bought a business car in 2024 and claimed €4,500 VAT. You join KOR on January 1, 2025.

Rekenvoorbeeld

Total VAT claimed€4,500
Revision period5 years (2024-2028)
VAT per year€4,500 ÷ 5 = €900
Annual repayment (KOR = 0% taxable use)€900

The €500 Exception

If the annual revision amount is less than €500 and the investment was made in a previous calendar year, no revision is required. Practical interpretation: If total VAT claimed on investments in revision period is less than approximately €2,500 (for movable goods), you likely won't face revision.

13. 2025 Rule Changes

Since January 1, 2025, several significant changes apply to the KOR. These are part of broader tax changes for freelancers in 2026:

The table below compares the old and new rules side by side, so you can see exactly what has changed:

ChangeBefore 2025From 2025
Minimum participation3 years mandatoryNo minimum—opt out anytime!
Deregistration timingLimited flexibilityCan deregister at end of any quarter
Exclusion after leaving3 years before rejoiningRest of current year + next year only
Registration methodPaper formsFully online via Mijn Belastingdienst Zakelijk
Foreign entrepreneursAllowed with fixed establishment in NLNo longer allowed (use EU-KOR instead)

New: EU-KOR (from 2025)

A new European Small Business Scheme (EU-KOR) allows Dutch entrepreneurs to apply for VAT exemption in other EU countries where they do business, provided total EU turnover stays below €100,000 and national thresholds in each country are respected.
Savings and money management for small business owners
The KOR can save you money — but only if it fits your business situation.

14. Decision Checklist: Should You Use the KOR?

Before deciding, ask yourself:
  1. What are my typical annual expenses and the VAT I'd lose by not being able to reclaim it?
  2. Do my clients actually benefit from VAT-free pricing? (Private consumers yes, businesses no)
  3. How much is the administrative simplification worth to me in saved time and accountant costs?
  4. Would VAT revision rules cost me money on recent investments?
  5. Is my turnover stable, or might I exceed €20,000 and face complications?

15. Conclusion

Use the KOR if:

  • Turnover stable at well under €20,000
  • Clients are mainly private individuals
  • Minimal business expenses
  • Value administrative simplicity

Avoid the KOR if:

  • Selling primarily to businesses (B2B)
  • Significant expenses or planned investments
  • Turnover fluctuates near €20,000
  • Recently claimed substantial VAT on investments
Key Takeaway
The 2025 changes make the KOR more flexible than ever—if it doesn't work out, you can leave and potentially rejoin sooner than before. Consider consulting a tax advisor (fiscalist) for complex situations.
