You’ve registered as a ZZP’er (freelancer), the invoices are coming in, and your business and grocery money are now hopelessly mixed in one account. The fix is a zakelijke rekening (business bank account). Here is whether you actually need one, what it costs, and the vocabulary to open it.
Do you need one?
Strictly, no, not by law. As guides to whether a business account is mandatory explain, a sole proprietor (eenmanszaak/ZZP) isn’t legally required to have a separate zakelijke rekening.
But it’s strongly recommended: it keeps business and private money apart, which makes your boekhouding (bookkeeping), BTW (VAT) returns and tax filing far cleaner. (A BV is generally expected to have one, and many banks require business use to be on a business account.)
What you need, and the cost
As Knab explains opening a business account, you need a KvK number, which you get on registering with the Chamber of Commerce. This is not a Knab quirk: every Dutch bank, Rabobank, ING, ABN AMRO and the app banks included, asks for the KvK registration, so a zakelijke rekening without KvK does not exist. If you earn a little from a hobby and are not registered, open a second private account and keep the hobby money there instead.
On cost, per comparisons of ZZP business accounts: roughly 7 to 15 euros/month depending on bank and features (Knab around 7 euros with starter deals; bunq from around 13). A nice detail: the account fee is deductible as a zakelijke kosten (business expense) on your tax return.
And a BV?
A BV (private limited company) is a separate legal person, so it needs a bank account in its own name: the notaris incorporating it will ask for one, salary and dividends flow through it, and mixing its money with your own is exactly what the corporate veil forbids. Opening it takes the BV’s KvK extract, the deed of incorporation and identification of every UBO (ultimate beneficial owner); banks screen BVs harder than sole traders, so allow a few weeks. The same comparison below applies, though the traditional banks are more used to BVs with foreign shareholders than the app banks are.
| Bank | Typical 2026 cost | Fits |
|---|---|---|
| Knab Zakelijk | first year free, then a few euros a month | ZZP’ers who want Dutch phone support and a Dutch IBAN |
| bunq | free basic business plan, paid tiers for more | app-first, multiple currencies, quick onboarding |
| Finom | a free solo plan | very low transaction volume |
| Rabobank / ING / ABN AMRO | roughly 10 to 15 euros a month | BVs, branch access, the widest acceptance |
Figures are from 2026 comparisons for ZZP’ers and change with promotions; check the bank’s own page before signing. Whatever you pick, the monthly fee is a deductible zakelijke kosten.
Choosing a bank
Compare on:
- monthly cost and transaction limits;
- included features (invoicing tools, bookkeeping links);
- app-first (Knab, bunq, Qonto) vs traditional (Rabobank, ING) with branch access.
Some offer starter deals (free for the first months). Pick on your transaction volume and banking style, not just the headline price.
A couple of practical pointers. Make sure the account supports iDEAL and incasso (direct debit) if you’ll bill clients or take recurring payments, and check whether it integrates with your boekhoudprogramma (accounting software like Moneybird or e-Boekhouden), which saves hours at tax time. If you’re a foreign founder, confirm the bank accepts your situation and ID; some online banks onboard non-residents more easily than the big traditional ones, so it’s worth checking before you set your heart on a particular bank.
The vocabulary
| Dutch | English |
|---|---|
| de zakelijke rekening | business account |
| het KvK-nummer | Chamber of Commerce number |
| de BTW | VAT |
| de zakelijke kosten | business expenses |
| de boekhouding | bookkeeping |
| de eenmanszaak | sole proprietorship |
Where it connects
A business account follows KVK and ZZP registration and exists to receive the invoices you issue. For the personal account underneath it, opening a Dutch bank account with or without a BSN.
The bottom line
A zakelijke rekening keeps your business and private money separate, not legally required for a ZZP sole trader, but strongly advised, and it makes your BTW and boekhouding far easier. You’ll need a KvK number; expect 7 to 15 euros/month (the fee is deductible). Learn zakelijke rekening, KvK, BTW and zakelijke kosten, compare banks on more than price, and your freelance admin gets dramatically cleaner.
Frequently asked questions
Do I need a business bank account as a freelancer in the Netherlands?
Not strictly, by law, a sole proprietor (eenmanszaak/ZZP) isn’t required to have a separate zakelijke rekening. But it’s strongly recommended: it keeps your business and private finances apart, which makes your bookkeeping, BTW (VAT) returns and tax filing far cleaner and clearer. A BV (private limited company) is generally expected to have one. Many banks also require business use to be on a business account.
What do I need to open a zakelijke rekening, and what does it cost?
You generally need a KvK number, which you get when you register your business with the Chamber of Commerce. Monthly costs typically run from about 7 to 15 euros depending on the bank and features (for example Knab around 7 euros, with starter deals; bunq from around 13 euros). Helpfully, the account fee is deductible as a business expense on your tax return, softening the cost.
Which bank should I choose for a business account?
Compare on monthly cost, transaction limits, included features (invoicing tools, bookkeeping integrations) and how mobile-first you want to be. Traditional banks (Rabobank, ING) and online players (Knab, bunq, Qonto) all offer ZZP accounts; some have starter offers (e.g. free for the first months). Pick based on your transaction volume and whether you value branch access or app-first banking, not just the headline price.
Can I open a zakelijke rekening without a KvK number?
No. Every Dutch bank, including Rabobank, ING, ABN AMRO, Knab and bunq, requires a KvK registration before opening a business account; the only exceptions are informal associations and public bodies. Register at the KvK first (it takes one appointment), then open the account. For small hobby income without a registration, a second private account does the job.
Does a BV need its own bank account in the Netherlands?
Yes. A BV is a separate legal person, so it needs an account in the company’s name: the notary asks for it at incorporation, salary and dividends run through it, and keeping company and private money apart is a legal duty for directors. Bring the KvK extract, the deed of incorporation and ID for every ultimate beneficial owner; screening takes longer than for a sole trader.
Which business bank account is best for a ZZP’er?
For a starting freelancer with few transactions, Knab (first year free, Dutch support, Dutch IBAN) or bunq’s free basic plan are the usual picks; Finom offers a free solo plan. Traditional banks such as Rabobank and ING cost roughly 10 to 15 euros a month and suit BVs and anyone who wants a branch. Compare on transaction limits, iDEAL and direct-debit support, and accounting-software links, not on the headline fee.
