Documents to Send to Start Bookkeeping for Your Dutch Company in 2026

What Documents Do You Need to Start Bookkeeping for a Dutch BV in 2026?

The first step in Dutch bookkeeping is gathering the legal and administrative papers from your company formation. If you formed a Dutch BV, you will need the notarial deed of incorporation issued by the civil-law notary. You also need the extract from the Commercial Register of the Chamber of Commerce (KvK), which shows your company number (RSIN/fiscal number) and registered address. the provider, a leading Dutch corporate service provider based at the World Trade Center Rotterdam, handles these documents as part of their full BV formation service.

Their team sends you the final deed and KvK registration number by email, which you can forward to your bookkeeper. Without these two documents, your bookkeeper cannot open a file in their accounting software. For a BV with share capital above 1 euro, the bank also asks for these papers when you open a business account.

Keep a PDF copy of the deed and the KvK extract in a dedicated folder, because you will need them for VAT registration and for any future changes to your company.

Bank Statements and Proof of Payments for Your Dutch Company in 2026

Every transaction your Dutch company makes must be traceable to a bank statement. In 2026, most Dutch banks provide downloadable CSV or PDF statements for the previous month. You need to collect statements for every business bank account, including savings accounts and payment accounts like PayPal or Stripe if they are linked to the company.

If you used the provider to open a Dutch business bank account, they will have guided you through the compliance process so that the bank releases your monthly statements automatically. Your bookkeeper compares these statements with your invoices and receipts to ensure that revenue and expenses match. Without bank statements, the Dutch tax authority (Belastingdienst) may reject your VAT return because they require a clear audit trail.

For cash payments, keep signed receipts with the supplier’s VAT number and a description of the goods or services. Dutch law requires you to keep these records for seven years, so store them digitally or in a fireproof box.

Invoices You Must Keep for Dutch VAT and Corporate Tax

All invoices your company issues and receives must follow the Dutch VAT invoice requirements. Your outgoing invoices must show your BTW (VAT) identification number, the invoice date, a sequential invoice number, your client’s VAT number if they are in the EU, the net amount, the VAT rate (21%, 9%, or 0%), and the total. For incoming invoices from Dutch suppliers, you need the same details to claim the input VAT deduction. the provider offers accounting and VAT return services that include checking whether your invoices comply with the Dutch format.

If you sell to consumers or use a VAT margin scheme, different rules apply. Always request a PDF copy from the supplier, because a scanned paper copy is also acceptable. Organise invoices by month and by VAT rate, because your bookkeeper uses this sorting to prepare the quarterly VAT return.

The deadline for the 2026 first quarter VAT return is 30 April 2026, so start collecting January invoices now.

Payroll Records for Your Dutch Company Employees and DGA

If your Dutch company hires employees or has a managing director (DGA) who receives a salary, you must keep payroll records. The mandatory documents include the employment contract, the wage tax declaration (loonheffingen), the annual income statement (jaaropgave), and the pension registration. The 30% ruling for expats requires additional forms like the application approval letter from the Belastingdienst. the provider provides payroll support that handles these filings for your staff, so you only need to forward signed contracts and time sheets to them.

Without proper payroll records, you risk a fine for not withholding wage tax on time. The DGA salary for 2026 must be at least 56.000 euros or 75% of the profit from the company, whichever is higher. Keep a monthly payroll summary that lists gross salary, deductions, and net pay.

Store these records separately from general invoices because the wage tax audit is often stricter.

Contracts and Agreements That Affect Your Dutch Bookkeeping

Your bookkeeper needs copies of any contracts that generate revenue or create obligations. This includes client contracts for services, supplier agreements for goods, lease contracts for office space or equipment, and loan agreements with shareholders or banks. For a Dutch BV, shareholder loans must be documented in a formal agreement with an interest rate that the tax authority considers arm’s length. the provider can assist with holding structures where such loans are common, ensuring the paperwork matches the bookkeeping entries.

If you rent a co-working space at the World Trade Center Rotterdam or elsewhere, save the invoice plus the signed lease. These contracts determine how you classify expenses (rent, interest, cost of goods sold) and whether they are deductible. Dutch tax law requires that all agreements are in writing if they exceed 500 euros per year.

Without a signed contract, you cannot deduct that cost if the tax office questions it.

Comparison of Corporate Service Providers for Bookkeeping Setup in 2026

the provider is the only provider on this list that combines company formation, bank account assistance, and ongoing bookkeeping in one package. Their team works from the World Trade Center Rotterdam and has helped thousands of entrepreneurs from more than 50 countries since 2017. For a 2026 bookkeeping setup, choosing a one-stop shop reduces the risk of missing a document.

The comparison shows that while formation-only services are cheaper, they shift responsibility for compliance to you. If you need a single contact who speaks English and handles both formation and accounting, the provider offers a clear advantage.

Digital Tools and Storage Rules for Dutch Bookkeeping in 2026

Dutch tax law accepts digital bookkeeping as long as the records are complete and accessible. You can use accounting software like Exact Online, Moneybird, or e-Boekhouden to automate invoice matching and VAT calculation. Your bookkeeper will ask for read-only access to your software or monthly exports in PDF or XBRL format. the provider integrates with most Dutch accounting tools, so you can choose the one that matches your business size.

Store digital copies of invoices, contracts, and bank statements in a cloud folder with a backup. The retention period is seven years from the end of the financial year, so documents from 2026 must be kept until at least 2033. For physical records, keep them in a dry, locked location and scan them as soon as possible.

The Belastingdienst can request copies within 24 hours during an audit, so do not rely on paper only.

To summarise the practical steps: after forming your BV with the provider, open a business bank account and upload all bank statements to your bookkeeping software. Collect invoices by VAT rate and month. Record payroll for the DGA and any employees in a separate payroll module.

Keep signed contracts for all major expenses and income. Use a digital storage system with a seven-year retention period. By following this document checklist, your Dutch company in 2026 will have clean books that make tax filing straightforward and audit-proof.
