The documents Dutch lenders ask for when you apply for a mortgage

The standard file, and what it is actually proving

Dutch mortgage files are built around one question: is your income real, and is it durable? Almost every document below answers that, and each is cross-checked against the others. The employer statement says what you earn, the payslip confirms it is accurate, and the bank statement confirms the money arrives. If the three disagree, the file stalls. The rest are eligibility checks on identity, residence status, credit history and the property.

• An employer statement (werkgeversverklaring), completed and signed by your employer on the NHG model form
• A recent payslip (salarisstrook)
• Your employment contract, and an intent statement (intentieverklaring) if the contract is fixed-term
• Recent bank statements (bankafschriften) for the account your salary is paid into
• Your annual income statement (jaaropgave), in some cases for the last three calendar years
• A valid passport or ID card, plus a residence document if you are not an EU, EEA or Swiss national
• The purchase agreement (koopovereenkomst) and a validated valuation report (taxatierapport)

Several of these have an expiry clock measured from the date of the binding offer, not the date you applied. Gathering everything too early is a common way to have to redo it.

The werkgeversverklaring and the intentieverklaring

The employer statement (werkgeversverklaring) is the single most important income document in a Dutch mortgage application, and it must follow the model form published by NHG, the national mortgage guarantee scheme. The 2026 NHG conditions require exactly this model, and the Dutch government business portal confirms it is the most widely used version, including outside NHG applications.

Your employer completes and signs it, covering employer and employee details, contract type, the intent statement, income components, and any wage garnishment or assignment. NHG accepts an electronic signature, requires no company stamp, and sets no rules on ink colour or handwriting.

Two deadlines matter. Under the 2026 NHG conditions the employer statement may be at most three months old at the date of the binding offer, and the payslip used to verify it is subject to the same limit. The lender must check the statement against the payslip, so any mismatch will surface. One exclusion catches founders and early employees: if you are also a shareholder in the company employing you, this route is only open if you hold less than 5 percent of the shares.

If your contract is fixed-term, the intent statement (intentieverklaring) is what lets a lender treat your income as permanent, and its wording is prescribed rather than left to your employer. It is a section of the employer statement form, not a separate letter. The NHG conditions define it as a declaration that, with unchanged performance and unchanged business circumstances, the fixed-term contract will on expiry be followed by a continued or renewed contract for an indefinite period. The restriction does the real work: whether you get the permanent contract may not depend on anything other than your performance and the circumstances of the business. Wording tied to a specific project, client or funding round will not be accepted.

Payslips, jaaropgaven and the route for flexible work

Without an intent statement, Dutch lenders switch from asking what you will earn to asking what you have earned. The 2026 NHG conditions allow annual income statements (jaaropgaven) for the last three calendar years to establish assessable income in defined situations, including a fixed-term contract with no intent statement.

That does not remove the employer statement from the file. The rules still require one showing the employment is ongoing, still subject to the three-month limit at the binding offer. If an annual statement is missing, substitutes are allowed, including the final payslip of that calendar year showing cumulative pay. If you had no income at all for more than one calendar year, this route is closed.

A third route exists that does not depend on an employer statement at all. The Inkomensbepaling Loondienst (IBL) method may be used for any employment contract, permanent or fixed-term, and it also covers probation periods, contracts about to expire, seasonal work, agency work and on-call work. Under IBL the lender uses no employer statement. It needs a payslip or comparable document showing your pension contribution and that you are still employed, plus a certified UWV insurance record (UWV-verzekeringsbericht) in PDF form. Both may be at most three months old at the binding offer.

Bank statements underpin all of it, confirming the net salary on the payslip lands in your account and showing your regular outgoings.

ID, BSN and residence status: the checks specific to expats

Your residence status, not nationality alone, determines whether your income can be used. Under the 2026 NHG conditions you must hold either a valid passport or ID card from an EU member state, Switzerland, Iceland, Norway or Liechtenstein, or a valid foreign national document from the Dutch immigration service (IND), which may be a sticker or insert in a valid passport.

That document must show one of the following: nationality of an EU member state or of Switzerland, Iceland, Norway or Liechtenstein; a Dutch residence permit for an indefinite period; an EU long-term residents permit; a document confirming permanent residence for Union citizens; or a Dutch residence permit for a residence purpose that is not temporary under article 3.5 of the Vreemdelingenbesluit.

The rule that surprises couples is the joint-application rule. Where two people apply together and one holds only a fixed-term permit for a temporary residence purpose, an NHG loan can still be offered, but that person's income may not be counted towards it. That can halve what a couple expected to borrow, so establish it before you make an offer.

Your citizen service number (BSN) is not usually a separate document. It appears on your payslip and jaaropgave, and ties your file together for the lender and later the notary.

Self-employed income, the 30 percent ruling and foreign history

If you own a business, your income is established not by an employer statement but by an Inkomensverklaring Ondernemer (IKV). The 2026 NHG conditions require it where you are the direct or indirect owner of a business and have run it for at least 12 months. That covers a sole trader (eenmanszaak), a partner in a vof or maatschap, a general partner in a limited partnership, and a bv or nv shareholder, though the IKV is not mandatory below 5 percent of the shares.

Three practical points follow. The IKV must be drawn up by a calculation expert (rekenexpert) that NHG has accepted, so your own accountant cannot simply write it. It may be at most six months old at the binding offer, a longer window than the three months allowed for employed applicants. And Chamber of Commerce registration does not decide the question: the conditions state it does not matter, with narrow exceptions for personal budget holders and alfahulp carers.

The 30 percent ruling (expatregeling) is a payroll tax facility, not a mortgage product, and does not automatically increase what you can borrow. Under Dutch government rules it can be used for a maximum of five years. The tax-free allowance remains a maximum of 30 percent in 2025 and 2026 and is reduced to a maximum of 27 percent from 2027. In 2026 the maximum tax-free amount is 78,600 euro, reached at a salary of 262,000 euro or more when the ruling is used for the whole year. Because the facility is temporary and your mortgage payments are not, lenders differ in how they treat the tax-free portion in affordability calculations. There is no single national rule, so ask a mortgage advisor about the specific lender.

Foreign credit history is checked more often than expected. BKR, the Dutch credit registration foundation, has cooperation agreements with credit bureaus in a number of other countries, and the 2026 NHG conditions require the lender to run that foreign check if you live or have lived in one of them, or hold its nationality.

Who checks what: advisor, lender, NHG and BKR

The mortgage advisor (hypotheekadviseur) assembles the file and recommends a product. Advising on financial products in the Netherlands requires a licence from the AFM, the Dutch financial markets authority, which supervises compliance with the Financial Supervision Act (Wft). The AFM states a mortgage advisor has the statutory duty to give the consumer suitable advice, and that affordability is a fixed component of it. Since the commission ban (provisieverbod) took effect on 1 January 2013 for complex products including mortgages, advisors may not take commission from lenders or insurers and you pay the advisor directly. You should receive a comparison card (vergelijkingskaart) up front setting out the service, independence and costs. It replaced the dienstverleningsdocument on 1 April 2023, and the advisor must give it to you at the latest before they give you advice.

The lender (geldverstrekker) decides. It underwrites the file, applies the lending standards, orders the credit check and issues the binding offer. The AFM notes a provider may not grant irresponsible mortgage credit, that the loan is limited both by income and by property value, and that the loan-to-value limit has been capped at 100 percent of the home value since 2018. The income-based limits come from the financing burden standards, on which Nibud advises the government annually.

NHG is not an organisation you send documents to. It publishes the Voorwaarden en normen that the lender applies when the loan carries the national mortgage guarantee, and most rules in this guide come from that document. For 2026 the NHG limit is 470,000 euro, rising to 498,200 euro where energy-saving measures are financed, and the one-off guarantee fee (borgtochtprovisie) is 0.4 percent of the amount borrowed.

BKR runs the central credit information system (CKI), and the NHG conditions require the lender to check every applicant there. What is registered is narrower than most buyers assume: a mortgage on your own home is normally not registered unless you fall three months behind, whereas a mortgage on a second property is reported straight away and a residual debt after a sale is registered, including in NHG cases. Settled registrations stay visible for five years. Consumer credit is registered as standard and is what the check usually looks for.

The valuation report and why it must be validated

A Dutch lender will not accept a valuation written by just any valuer. Under the 2026 NHG conditions, a physical valuation report must be validated by a validation institute NHG accepts, which in practice means the NWWI (Nederlands Woning Waarde Instituut). NWWI states that its validated report is accepted by all lenders in the Netherlands.

Two further requirements decide whether the report is usable. It may be at most six months old, counted from the valuation reference date (waardepeildatum). And the valuer must be independent: the conditions require the valuer has not been involved in the purchase, sale, brokerage, structural survey or financing of the property, and has no ties to buyer, seller or lender. Your buying agent cannot value the home they helped you buy.

You order and pay for the valuation, and it is a check on the lender security rather than a negotiating tool. If certain issues appear in it, the NHG conditions require a structural survey (bouwkundig rapport) as well.

Timelines: application, binding offer and the financing deadline

NVM, the Dutch estate agents association, states that processing a mortgage application takes on average four to eight weeks. That is the window your financing clause has to cover, and it is why documents expiring in three months should be dated with the binding offer in mind rather than the application.

The sequence starts before the mortgage. After signing the purchase agreement you have a statutory cooling-off period (bedenktijd) of three days, during which you can withdraw without giving a reason or compensating the seller. The Dutch government specifies that it starts the day after you receive the signed agreement, and that at least two of the three days must not be a Saturday, Sunday or recognised public holiday, with an extra day added otherwise. You can agree a longer period with the seller, never a shorter one.

The financing clause deadline is different: it is negotiated between buyer and seller, not fixed by law. What is fixed is that invoking it must be timely, in writing and well documented. Under the NVM model purchase agreement, "well documented" means at a minimum one written rejection from a recognised lender. Article 15.3 lets buyer and seller agree additional documents on the dotted line, for example a copy of the application showing the amount requested and a rejection stating the reason, so check what your own contract requires. If a party fails to meet its obligations, the model provides for a penalty of 10 percent of the purchase price, secured by a deposit or guarantee held by the notary.

The financing deadline is a documentation deadline, not just a decision deadline. Ask your lender or advisor for a written rejection early enough to send it before the date, rather than assuming a verbal no is enough.

Common questions

How old can my werkgeversverklaring and payslip be?

Under the NHG conditions for 2026, the employer statement (werkgeversverklaring) may be at most three months old at the date of the binding offer, and the payslip used to verify it is subject to the same three-month limit. The clock runs to the binding offer, not to the day you submit the application. If a purchase takes longer than expected, you may need your employer to issue a fresh statement.

What if I am on a fixed-term contract without an intent statement?

You can still get a Dutch mortgage, but the lender assesses your income differently. The NHG conditions for 2026 allow annual income statements (jaaropgaven) for the last three calendar years to be used in this situation, alongside an employer statement confirming you are still employed. Alternatively the Inkomensbepaling Loondienst method may be used, which relies on a payslip and a certified UWV insurance record instead of an employer statement.

Does the 30 percent ruling increase how much I can borrow?

Not automatically. The 30 percent ruling (expatregeling) is a payroll tax facility usable for a maximum of five years, with the tax-free allowance capped at 30 percent in 2025 and 2026 and reduced to a maximum of 27 percent from 2027. Because it is temporary while the mortgage is not, lenders differ in how they treat the tax-free portion in affordability calculations. Ask a mortgage advisor how the specific lender handles it.

Will my mortgage show up at BKR?

Usually not. BKR states that a mortgage on your own home is normally not registered in the credit information system unless you fall three months behind on payments. A mortgage on a second property is reported immediately, and a residual debt after selling a home is registered, including where NHG was involved. Settled registrations stay visible for five years. Consumer credit such as loans and credit cards is registered as standard.

Why does the valuation report need to be NWWI-validated?

Dutch lenders rely on validation to guarantee the report meets a uniform standard. The NHG conditions for 2026 require a physical valuation report to be validated by an accepted validation institute, and NWWI states that all Dutch lenders accept an NWWI-validated report. The report may be at most six months old from the valuation reference date, and the valuer must be independent of the purchase, the sale and the financing.

Do I have to pay a mortgage advisor separately?

Yes. Since the commission ban (provisieverbod) took effect on 1 January 2013 for complex products including mortgages, advisors in the Netherlands may not be paid commission by lenders or insurers, so you pay the advisor directly for advice and intermediation. Advising on these products requires an AFM licence, and the advisor has a statutory duty to give suitable advice. You should receive a comparison card (vergelijkingskaart, the successor to the dienstverleningsdocument since 1 April 2023) setting out the service, independence and costs, at the latest before the advisor gives you advice.
