The cost of employing a developer in the Netherlands is roughly €87,400 to €92,800 a year for a €70,000 salary, before sick pay, recruiting and equipment. Budget by line item, not a flat percentage on top: pension and your premium tier move the total most. We'd hire an employee for a role you'll still need in two years, and use nearshore capacity when the end date is unclear.
What lines sit between gross salary and what you pay in the Netherlands?
Seven lines. Two are your choice (salary and pension), the rest are statute. The Belastingdienst's 2026 rate table lists the premiums.
| Line | 2026 rate | Applies to | Statute or choice |
|---|---|---|---|
| Base salary | Your offer | Gross annual salary | Choice |
| Holiday pay | 8% minimum | Past year's gross salary | Statute |
| AWf (unemployment) | 2.74% low, 7.74% high | Premium wage | Statute |
| Aof (disability) | 6.27% or 7.63% | Premium wage | Statute |
| Zvw (health levy) | 6.10% | Premium wage | Statute |
| Whk | Set in your decision notice | Premium wage | Statute |
| Pension | 1-14% typical (pension adviser) | Salary minus a fixed franchise | Choice, or sector rule |
Premium wage is capped at €79,409 for 2026, so a very senior salary stops adding premiums at the cap. The percentages are 2026 rates. Check the Belastingdienst's 2027 table before you budget next year.
Worked example: a developer on €70,000
The low case uses the cheapest pension and Aof tier, the high case the richest.
| Line | Low case (€) | High case (€) |
|---|---|---|
| Base salary | 70,000 | 70,000 |
| Holiday pay (8%) | 5,600 | 5,600 |
| Premium wage | 75,600 | 75,600 |
| AWf, low tier | 2,071 | 2,071 |
| Aof | 4,740 | 5,768 |
| Zvw | 4,612 | 4,612 |
| Pension, employer share | 339 | 4,744 |
| Total | 87,362 | 92,795 |
| Over base salary | +24.8% | +32.6% |
Both cases use the low AWf tier. Premium wage sits below the cap, and the pension base is €50,828 with the employer paying two-thirds. The total excludes Whk, sick pay, recruiting, equipment and any notice or severance cost.
How much is the holiday allowance, and when do you pay it?
business.gov.nl sets the minimum at 8% of the employee's gross annual salary for the past year. You normally pay it once a year, in May or June, and it's paid out when the employee leaves, so a mid-year exit means a payout in the final pay run.
Treat it as part of the salary line, not a bonus. Anyone quoting "salary plus 30%" without showing it separately has probably folded it into something else.
What do employer premiums add: AWf, Aof, Zvw?
The Belastingdienst's page on WW premium differentiation gives AWf two tiers. The low tier needs an indefinite, written contract that isn't on-call. A contract that misses any of those conditions pays the high tier, apart from a few narrow exceptions the page lists.
Aof also has two tiers, and which one applies depends on the size of your premium payroll. Look at the notice the Belastingdienst sent you rather than guessing. Zvw is a flat employer levy up to the cap. Whk is individual or sector-based, so the figure comes from your own decision notice.
What does a pension add, and is it optional?
There's no general legal duty to offer one, but the KVK says about 70% of companies are obliged through a sector scheme or collective agreement. Check your sector fund before you set a number.
The pension base is salary minus the AOW franchise of €19,172 (2026), capped at €137,800. A pension adviser quoted by the KVK says clients typically choose 1% to 14% of the base; employers often pay two-thirds of it. Together with the Aof tier, that choice is the biggest swing in the budget.
What if the developer is ill for a year?
business.gov.nl says you pay at least 70% of wages for up to two years. In the first year only, if that falls below minimum wage, you top it up to the minimum. This is a cost event, not a monthly line, so hold it as a reserve and ask your payroll provider about cover.
Does the 30% ruling cut to 27% change my cost?
The ruling lets you pay a qualifying foreign hire a tax-free allowance. From 1 January 2027 the maximum drops to 27%, according to business.gov.nl. Hires who started before 1 January 2024 keep 30% for up to five years. Hires who started from 2024 to 2026 get 30% through 2026 and 27% from 2027.
On the example salary, that moves €2,100 (three points of the salary) from tax-free to taxable, which lowers the employee's take-home and leaves the employer lines above untouched. You pay more only if you raise gross salary to hold their net. The gross-up has to exceed the extra tax, because the added salary is taxed too, so ask your payroll provider for the figure at your employee's tax rate. If you're recruiting from abroad for a 2027 start, quote the offer at 27% from day one.
When does a nearshore engineer cost less than this hire?
Break-even hourly rate is total employer cost divided by billable hours. At 1,600 hours a year, the example works out to €54.60 an hour in the low case and €58.00 in the high one. HighCircl's nearshore rate is €45-105 an hour, so only the bottom of that range, up to roughly €55-58, comes in below the break-even; the rest costs more per hour. For the same break-even in Germany and Poland, see the German and Polish version of this math.
So the case for nearshore isn't price per hour. It's commitment, hours and end date. An employee's paid year includes holidays and sick days, while a contractor invoices only the hours worked, so state the hours before you compare. To test fit, run a two-week paid trial or check your own time-to-first-PR data. For the contractor route inside the Netherlands, mind the Dutch freelancer rules (Wet DBA).
What this means for your Dutch hiring budget
Budget each Dutch developer from the line items and put a range on the pension line before you quote an offer. Then ask your payroll provider four things: which AWf and Aof tiers you're in, what your Whk premium is, whether holiday pay counts as premium wage (the example assumes it does), and whether the ruling's tax-free allowance counts as premium wage too.
If the work will outlast two years, the employee lines above are your budget. If it might not, price nearshore on the hours you'll actually use. To see the same decision across other countries, read our guide to software development team cost in Europe, and the rest of our software development cost guides.
Hiring a nearshore engineer through HighCircl
Nearshore doesn't win on hourly price against a Dutch employee, but it fits when you can't see the end of the work or need fewer hours than a full year. HighCircl's rate carries a 20% margin that's capped and disclosed, and there's no minimum hour commitment, so you pay for the hours you use. See hiring senior engineers through HighCircl for how a match works.
FAQ
Is holiday pay included in the salary?
No. It's at least 8% of gross annual salary on top, normally paid in May or June and paid out when the employee leaves. On the €70,000 example that's €5,600.
How much do employer premiums add in the Netherlands?
In the example, AWf, Aof and Zvw come to roughly €11,400 to €12,500 on 2026 rates, about 15% to 16.5% of premium wage depending on the Aof tier. The high AWf tier and your Whk premium add more.
Do I have to offer a pension?
There's no general legal obligation, but about 70% of companies are covered by a sector scheme or collective agreement. Check your sector fund first. Where it's your choice, employers often pay two-thirds of a 1% to 14% contribution.
What happens to the 30% ruling in 2027?
The maximum tax-free share falls to 27% from 1 January 2027. Hires who started before 2024 keep 30% for up to five years; 2024 to 2026 starters move to 27%. Your costs rise only if you top up gross pay to hold the employee's net.
How long must I pay a sick developer?
At least 70% of wages for up to two years, with a top-up to minimum wage in the first year only.
