Bookkeeping in the Netherlands, explained

Dutch rules apply to everyone equally. The explanations about them exist almost exclusively in Dutch — which is precisely the problem if you run a business here and don't read that language.

In short

Bookkeeping in the Netherlands comes down to a handful of deadlines and threshold amounts. Your VAT return and the payment that goes with it are due on the last day of the month after your filing period: file quarterly and the third quarter is due by 31 October. You keep your records for seven years, and ten years for anything involving immovable property. Stay under € 20,000 in turnover per calendar year and the small businesses scheme (KOR) lets you stay outside VAT altogether; sell to private customers in other EU countries and the threshold is € 10,000 a year. Spend 1,225 hours a year on your business and that is worth € 1,200 in self-employed deduction in 2026. Work as a subcontractor in construction and you charge your contractor no VAT but write 'btw verlegd' on the invoice. Together with what must be on your invoice, this knowledge base explains those nine subjects in five languages: Dutch, English, Polish, Hungarian and Romanian. If a letter uses a word like voorlopige aanslag, naheffingsaanslag or suppletie, you will find it in the glossary: twenty-nine Dutch terms, each explained in two or three sentences. If you're unsure whether you can do all this yourself, the guide on doing your own bookkeeping or hiring an accountant sets out when doing it yourself works and when an accountant is a good idea.

What is due when

The deadlines and threshold amounts every entrepreneur in the Netherlands runs into, on a single list. Amounts that change from year to year are shown for 2026; everything below was checked against the Dutch Belastingdienst.

VAT return
Due on the last day of the month after your filing period — both the return and the payment. File quarterly and the July-to-September quarter is therefore due by 31 October.
Income tax return
The deadline is stated in the return letter from the Dutch Belastingdienst; it is often 1 May. Did you move to or leave the Netherlands that year? Then you file an M-form instead of the ordinary return.
Keeping your records
Seven years for your records as a whole: invoices, bank statements, the general ledger and the calculations underneath. Ten years for data on immovable property. Keeping them digitally is allowed.
Small businesses scheme (KOR)
A maximum of € 20,000 in turnover per calendar year, and that limit applies to this year as well as the year before. Join it and you charge no VAT — and you can no longer deduct the VAT on your own purchases.
Selling to private customers in the EU
Up to € 10,000 per calendar year across all EU countries combined you simply charge Dutch VAT. Above that, the VAT of your customer's country applies; you report it in one place through the One Stop Shop (OSS).
Self-employed deduction
1,225 hours per calendar year on your business, and more time on it than on other work. In 2026 that is worth € 1,200, plus up to three times € 2,123 in starter's deduction during your first years.
Investment deduction (KIA)
Invest between € 2,901 and € 398,236 in business assets in 2026 and you get an extra deduction from your profit. An asset costing less than € 450 does not count towards that total.
