What is the KOR scheme in the Netherlands?

KOR is the Dutch small business VAT scheme that can simplify VAT by allowing eligible small businesses to stop charging VAT and reduce VAT filings. The trade-off is you generally can’t reclaim input VAT on expenses.

Do I need to charge VAT on side hustle invoices in NL?

If you’re VAT-registered, yes. If you qualify for KOR and opt in, you typically do not charge VAT. The right answer depends on your turnover and expense profile.

Is Dutch side income taxed separately from salary?

No. It’s combined for income tax. That’s why rate floors should be set based on post-tax take-home, not just market rates.

What’s the easiest bookkeeping setup for a Dutch side hustle?

Separate bank inflows for the side hustle, a monthly expense log, and a VAT bucket (if VAT applies). If you keep it monthly, filings become trivial.

Do I need to register at KVK for a freelance side hustle?

Often yes, especially if you operate with continuity and invoice clients. Registration clarifies VAT obligations and makes invoicing credible to clients.

What’s the biggest Netherlands side hustle tax mistake?

Mixing VAT cash with spendable cash. If VAT applies, park it immediately and you’ll never get surprised at filing time.

Side hustle tax in the Netherlands (2026 guide)

Dutch freelancing is clean if you keep it simple: register for VAT when required, understand the KOR small business scheme, and set aside cash for income tax because it stacks on top of employment income.

When you have to register in the Netherlands

Threshold

VAT depends on activity + KOR eligibility

Most freelancers register and file VAT unless they qualify for the KOR small business scheme. Income tax reporting applies to profit; VAT is the part that surprises people because you can owe it even when cashflow feels 'small'.

What you owe: income tax + VAT (if applicable)

Freelance profit is taxed progressively. VAT is charged on invoices when you’re VAT-registered; KOR can simplify VAT but changes how you invoice.

Income tax: progressive based on total income (employment + business profit).
VAT (BTW): charged on invoices when registered; filed periodically as required.
KOR scheme: can remove VAT charging/filing if eligible, but you also generally can’t reclaim input VAT.

How to register and file

Step 01
Register your business and VAT status
Register (typically via KVK) and ensure your VAT number / filing obligations are clear. If eligible, evaluate KOR before your first invoices.
Step 02
Invoice with correct VAT wording
If VAT-registered, invoices must include VAT and your VAT ID. If using KOR, invoices need the correct KOR note (no VAT charged).
Step 03
Track income and expenses monthly
Keep receipts, subscriptions, equipment costs and travel logs. Separate accounts make VAT and profit tracking far easier.
Step 04
File VAT returns and annual income tax
File VAT returns as required and include business profit in your annual income tax return.

Worked example

You work full-time in Amsterdam and earn €58,000/yr. You earn €12,000 from freelance marketing in 2026 and have €2,000 of business expenses.

Gross side income

€12,000

Tax on profit (indicative)

≈ €3,000

Profit €10,000 is taxed at your marginal rate. Budget 30% of profit until your actual assessment. If VAT applies, ring-fence VAT on every invoice separately from income tax.

Common pitfalls

Assuming KOR is always the best option
KOR reduces VAT admin, but it can be worse if you have meaningful VAT-able expenses (you lose input VAT reclaim). Compare both options before you commit.
Not setting aside VAT cash
If you’re VAT-registered, part of every invoice belongs to the tax authority. Treat it as not yours and park it immediately.
Underestimating tax when you also have a salary
Side profit stacks on top of employment income. If you price based on your 'spare time' rather than post-tax take-home, you underquote.

From tax to take-home

Knowing the tax floor is the first half of the calculation. The second half is what to charge in the first place — so the post-tax number you see in your bank account actually moves the needle.
