VAT returns as a freelancer: explained step by step

Filing quarterly VAT (BTW) returns as a freelancer in the Netherlands does not have to be complicated. Below we explain each step, including deadlines, deductions and the KOR scheme.

As a freelancer (ZZP'er) in the Netherlands you must charge VAT (BTW) on invoices unless you use the KOR scheme. You file a VAT return with the Belastingdienst every quarter.

Quarterly deadlines

QuarterFiling + payment deadline
Q1 (Jan–Mar)30 April
Q2 (Apr–Jun)31 July
Q3 (Jul–Sep)31 October
Q4 (Oct–Dec)31 January (next year)

How to file your VAT return (5 steps)

1

Step 1: Calculate your turnover (VAT basis)

Add up all invoices you sent during the quarter, excluding VAT (BTW).

2

Step 2: Calculate output VAT

Turnover × 21% (or the applicable rate) is the VAT you must pay.

3

Step 3: Deduct input VAT

You may deduct VAT on business purchases such as laptops, subscriptions and office supplies.

4

Step 4: Submit via Mijn Belastingdienst Zakelijk

Log in with DigiD or eHerkenning and enter the requested amounts.

5

Step 5: Pay the VAT due

Pay on time with the correct payment reference to avoid late payment penalties.

KOR scheme: no VAT under €20,000 turnover

If your annual turnover stays below €20,000 you can apply for the Kleine Ondernemersregeling (KOR). You then do not charge VAT and do not file returns, but you cannot deduct input VAT either.

Note

Once registered for KOR you are committed for at least 3 years. Discuss with your accountant whether this is beneficial.
