What is the KOR?
A voluntary VAT exemption for entrepreneurs below €20,000 turnover per calendar year. Opting in means: zero VAT on invoices, zero quarterly returns, and zero input-VAT deduction on costs and investments. Since 2020 the KOR works as a genuine exemption.
Who benefits
The KOR pays off with three traits combined: customers who are mainly private individuals (your invoice becomes effectively 21% cheaper for them), few VAT-carrying business costs, and a stable turnover under €20,000. Typical fits: part-time instructors and teachers, small-scale creatives, first-year starters.
When the KOR costs money
- Mainly B2B clients: they deduct your VAT anyway — the KOR only forfeits your own input deduction.
- High business costs: a €1,500 laptop carries €260 of deductible input VAT — gone with the KOR.
- Investments coming: a car, machine or expensive software carries thousands in VAT.
- Growth path: crossing €20,000 forces the switch to regular VAT mid-year.
Worked example
A yoga instructor bills €15,000 to private clients with €1,000 (ex VAT) in costs. With the KOR: profit €13,790. With regular VAT: profit €14,000 — and lesson prices rise from €65 to €79 for her private clients. The KOR wins here exactly when clients are price-sensitive; the €210 input deduction is the price of that positioning.
Crossing the threshold
Crossing €20,000 ends the KOR immediately, with regular VAT from that supply onward and a 3-year re-entry block. Filing mechanics after the switch: filing Dutch VAT returns. Last verified: 19 July 2026.
