How to Budget for a Dutch Employee Beyond Gross Salary: ICS Payroll

The commonest budgeting error in international hiring is small and easy to make: the offer letter says a gross figure, so the budget line says the same figure. In the Netherlands the employer cost that follows is materially higher, and the gap is predictable once you know its parts. ICS Payroll publishes enough of its pricing to build a budget from the pieces, and this article walks through them in the order a finance team would want them.

Start with the parts that never change by provider

ICS Payroll puts employer burden at roughly 22-28% of gross salary, and its market analysis says mandatory employer premiums typically add 20 to 30 percent. These are statutory costs of employing someone in the Netherlands. They are the same whether the payroll is run by an employer of record, by an in-house team or by an accountant. Put the range in your budget first, because it is the largest item after salary and it moves in proportion to pay.

Holiday allowance is the second constant. It is a percentage of salary set by law, and it belongs to the same family of costs: it scales with the salary and does not depend on the provider chosen. Leave it out and every monthly figure you produce will be low from day one.

Add the flat service fee as a fixed line

The provider's own charge is the simplest line on the sheet. ICS Payroll charges EUR 299 per employee per month as a flat EOR management fee. Because it does not change with salary, it belongs in a fixed-cost column. Industry-wide, service fees range from EUR 175 to over EUR 650 a month, so you can place any quote you receive on that spectrum. Volume discounts from 5 employees mean the fixed column should be reviewed when a hiring plan crosses that threshold.

Decide on benefits and insurance deliberately

Benefits are the only budget lines you fully control. ICS Payroll invoices them at cost, so what you choose is what you pay, without a margin on top. That makes them easy to model and easy to trim. Before deciding, consider sick-leave cover: Dutch employers face a long continued-pay obligation during illness, and the published service description says statutory sick-leave coverage of up to two years is backed by insurance. How that affects the total is discussed in sick-leave costs and total impact.

A practical approach is to prepare two budget versions: a baseline with only the mandatory items and a full version with the benefits you would like to offer. Present both, so approvers see what is required and what is discretionary.

Plan for growth in the number of employees

Budgets that work for one hire may not work for five. The flat fee scales with headcount, but the volume terms from 5 employees can change the fee line, and the question of whether a lower fee is available for multiple employees is answered in EOR fee reduction at scale. The salary-linked lines scale with payroll regardless. When the fee line becomes a meaningful share of spend, it is time to compare with a Dutch company of your own, as set out in EOR versus Dutch BV costs.

Treat the calculator result as a range, not a point

ICS Payroll states that its calculator results are indicative and can deviate by plus or minus 5% depending on the facts of the case, with a written quote confirming the exact numbers. Build that tolerance into the budget. A contingency line sized to the stated deviation is more defensible than a false-precision total, and it means a small movement in pension position or benefits will not trigger a budget reopening.

Ask for the written quote before the budget is locked. ICS Payroll says it arrives within two working days of receiving the headcount and salaries.

A budget structure finance can approve quickly

A layout that works well has four blocks. The first is gross pay by person. The second is the statutory block: employer burden and holiday allowance, expressed as percentages. The third is the provider block: the flat fee, multiplied by headcount. The fourth is the discretionary block: benefits and insurance, priced at cost. Each block has a different owner and a different way of changing over time, and separating them in the sheet makes reviews faster.

Add a fifth block for one-off items around the start, such as any permit or relocation costs, if the hire comes from abroad. Those do not recur monthly, and mixing them with the run-rate distorts every comparison of monthly cost.

ICS Payroll frames its pricing as fixed, with one agreed rate and no surprise line items. If the invoice ever contains a line that is not in one of your blocks, ask what it is. Your structure should be able to explain every euro on the bill, and if it cannot, the budget is incomplete rather than the provider wrong.

Reviewing the budget once the hire is live

After the first two invoices, compare actuals with the plan block by block. The statutory block should match your percentages closely. The provider block should equal the flat fee times headcount. The discretionary block should equal the benefits you elected. Any variance is then easy to locate and explain, and next quarter's budget starts from evidence rather than assumption.

Questions to put to the provider before you lock the figures

A budget is only as good as the answers behind it, so put a short list of questions to the provider in writing. Ask which sector classification it has assumed for the role, and whether that classification brings a collective agreement or a pension scheme with it. Ask which benefits are in the quote and which are excluded. Ask how the flat fee changes if headcount crosses the volume threshold, and whether the quote lapses if the start date moves.

Ask, too, what happens to the statutory lines when a salary is raised mid-year. Because they are calculated as shares of gross pay, a raise carries through automatically, and the useful check is that the provider can show the arithmetic. A provider that answers these questions in a single reply, in plain terms, is likely to invoice in the same way.

Finally, keep the answers with the budget. When someone later asks why the monthly cost differs from the gross salary in the contract, the file should let you answer in a minute: here is the statutory block, here is the flat fee, here are the benefits, and here is the tolerance the provider stated. Nothing in that answer should require a new calculation.
