Best Payroll Software for the Netherlands in 2026

Loonbelasting (wage tax) is withheld from employee salaries based on the annual tax tables provided by the Belastingdienst. The Dutch income tax system has three boxes: Box 1 (employment income) with progressive rates from ~36.97% (on income up to ~EUR 75,518) to 49.50% (above that threshold) for 2026. The loonheffingskorting (general tax credit) is applied automatically for employees who submit the loonbelastingverklaring (payroll tax declaration) and reduces the effective tax rate. Employers must file loonaangifte (payroll tax return) monthly with the Belastingdienst and remit withheld taxes.

Social insurance premiums are part of the loonheffing. Volksverzekeringen (national insurance) include AOW (state pension, ~17.9%), Anw (survivor's benefit, ~0.1%), and Wlz (long-term care, ~9.65%), totaling approximately 27.65% on income up to ~EUR 38,441. Werknemersverzekeringen (employee insurance) include WW (unemployment — differentiated rates under WAB), WIA (disability — differentiated by employer), and ZW (sickness) — all employer-paid with rates varying by industry and employer history. ZVW (health insurance) employer contribution is approximately 6.68% of salary up to the maximum contribution base.

The 30% ruling allows qualifying expatriate employees to receive up to 30% of their salary (including the 30% allowance) as a tax-free extraterritorial cost reimbursement. To qualify, the employee must be recruited from abroad, possess specific expertise that is scarce in the Dutch labor market, and earn above the minimum taxable salary threshold (~EUR 46,107 for employees under 30 with a master's degree, or ~EUR 41,954 for scientific researchers). The ruling applies for a maximum of five years and must be applied for jointly by employer and employee with the Belastingdienst.

Vakantiegeld (holiday allowance) of minimum 8% of gross annual salary is a legal entitlement under the Wet minimumloon en minimumvakantiebijslag. Most employers accrue this monthly (reserving 8% each month) and pay it as a lump sum in May or June. The holiday allowance is subject to loonheffing when paid. Additionally, Dutch employees are entitled to a minimum of 20 vacation days per year (for full-time workers), with many CAOs (collective labor agreements) providing 25 days or more.

Pay frequency in the Netherlands is monthly, with salaries typically paid around the 25th of the month. Employers must provide payslips (loonstrook) showing gross salary, loonheffing, social premiums, pension contributions, and net salary. The annual jaaropgave (annual statement) must be provided to employees showing total income and withheld taxes for the tax year. Employers file monthly loonaangifte with the Belastingdienst and annual polisadministratie data with UWV (Employee Insurance Agency). The Belastingdienst can audit payroll records going back five years.

Loonbelasting (wage tax) calculation requires handling the Dutch tax bracket system, the loonheffingskorting (payroll tax credit), and the various social insurance premiums that are collected alongside income tax. Your software must apply the correct combinatiekorting, ouderenkorting, and other tax credits based on employee circumstances. The Belastingdienst provides annual tax tables (loonbelastingtabellen) that must be implemented correctly at the start of each year.

The 30% ruling is critical if you hire expatriate workers. Qualifying employees can receive up to 30% of their gross salary as a tax-free reimbursement for extraterritorial costs. Your payroll software must correctly implement the 30% ruling — splitting salary into a taxed portion and a tax-free portion, applying the correct tax tables to the reduced taxable base, and tracking the ruling's five-year duration per employee. Incorrect application either overtaxes the employee or creates a Belastingdienst liability.

Holiday allowance (vakantiegeld) is legally mandated at a minimum of 8% of gross annual salary, typically paid as a lump sum in May. Most payroll systems accrue this monthly and process the payment in May's payroll run. The holiday allowance is subject to its own tax treatment — it is often taxed at a higher rate because it pushes the employee into a higher bracket for that month. Your software must handle both the accrual and the special tax treatment.

Dutch social insurance premiums include werknemersverzekeringen (employee insurance — WW, WIA, ZW) and volksverzekeringen (national insurance — AOW, Anw, Wlz). The employer pays the premiums for werknemersverzekeringen, with rates that include the differentiated WW premium under WAB (higher for flexible contracts, lower for permanent contracts). Your software must apply the correct WAB premium rate based on contract type and flag changes when employees transition between contract types.

Pension (pensioen) administration varies by employer and sector. Many industries have a mandatory sector pension fund (bedrijfstakpensioenfonds), while others provide pension through an insurance company or premium pension institution (PPI). Your payroll software must handle pension contribution deductions at the correct rates, apply the pension franchise (franchise amount below which no pension accrual occurs), and report contributions correctly. Pension handling is one of the most complex aspects of Dutch payroll.

Dutch payroll is more complex than many expect, primarily because of the extensive social insurance system and the interaction between income tax and social premiums. The unified loonheffing (payroll levy) combines income tax and social insurance premiums into a single withholding, but the underlying calculations are separate, with different bases and caps for each component. Payroll software that presents this correctly on the payslip — showing the loonheffing total while tracking each component separately — gives both employer and employee accurate insight.

The WAB (Wet Arbeidsmarkt in Balans) reform significantly affects payroll by differentiating WW (unemployment insurance) premium rates based on contract type. Permanent contracts (vast contract) receive a lower rate, while flexible and on-call contracts receive a higher rate. This premium differentiation must be tracked per employee and adjusted when contract types change. Some payroll platforms still struggle with the real-time tracking of contract type changes and the retroactive premium corrections that can result.

For companies hiring knowledge workers from outside the EU/EEA, the 30% ruling is often the deciding factor in the employment offer. The tax savings for a qualifying employee are substantial — on a EUR 70,000 gross salary, the 30% ruling effectively exempts EUR 21,000 from Dutch tax. But the ruling has specific eligibility criteria (minimum taxable salary threshold, distance requirement, scientific or specialist expertise), and the payroll implementation must be precise. Incorrect application can trigger Belastingdienst corrections and employee-level tax assessments.

Most small to mid-size Dutch employers use local salarisadministratie (payroll administration) providers or accountants for payroll processing. The Dutch market has well-established local providers that offer deep compliance at competitive pricing. Global platforms add value when a company has multi-country operations and needs consolidated reporting. For Netherlands-only operations under 200 employees, a local provider almost always provides better value and deeper Dutch compliance than a global platform.
