Two offers land in your inbox on the same Tuesday. One pays €200 more a month gross. The other has a lease car, a fatter pension contribution, and a recruiter who casually mentioned "we handle the 30% ruling paperwork ourselves." Comparing them by gross salary alone is like judging two apartments by square footage without checking whether the roof leaks. Here's how to actually compare what lands in your account.
The trap almost everyone falls into
Offer A: €4,800 gross a month, no extras. Offer B: €4,600 gross, but with a 8.3% pension contribution matched by the employer and a company car with low personal bijtelling. On paper, A looks like the better deal by €200. Run both through an actual net pay calculation and B can easily come out ahead, because gross salary is only one line in a much longer spreadsheet.
Dutch income tax is progressive across three Box 1 bands, and on top of that, the algemene heffingskorting and arbeidskorting phase in and out at different income levels. That means an extra €200 gross a month doesn't turn into an extra €200 net, it turns into whatever's left after the marginal rate at your specific income level, which sits at 37.56% for most middle incomes and 49.5% once you're in the top band. Meanwhile, benefits like pension contributions get deducted from your taxable income before those brackets even apply, which is a completely different mechanism with a completely different effect on your actual take-home pay.
The only reliable way to compare two offers is to run each one, separately, through a full net pay calculation with its own benefits, pension rate, and 30% ruling status, and then compare the two monthly numbers that come out the other end. Everything else is a guess dressed up as arithmetic.
Not all "extras" in an offer letter are worth the same. Some reduce your taxable income directly, some are simply nice to have, and some are worth less than they sound once you account for the tax on them. Here's a rough order of how much they typically matter:
| Benefit | Why it matters for net pay |
|---|---|
| 30% ruling eligibility | Usually the single biggest lever, since up to 30% of salary becomes tax-free instead of taxed at your marginal rate |
| Employer pension contribution | Reduces taxable income now, but is deferred income, not cash you can spend this month |
| Holiday allowance rate above the 8% minimum | A higher CAO percentage compounds on your whole gross salary, not just the base |
| Company car | Comes with a taxable bijtelling added to your income, so it's a benefit with a built-in cost, not free money |
| Travel allowance / thuiswerkvergoeding | Usually tax-free up to the statutory rate, so it's genuinely additive to net pay, just a smaller amount |
The company car isn't automatically a win
A lease car sounds like pure upside until you learn about bijtelling, the taxable addition to your income for private use of a company vehicle. Depending on the car's list price and CO2 emissions, that addition typically runs 16% to 22% of the car's value, added to your taxable salary every single month. For an expensive car, the extra tax can quietly eat a meaningful chunk of what looked like a free perk. Ask for the exact bijtelling percentage and the car's cataloguswaarde before assuming a lease car is a clean win over a cash allowance of similar value.
Yes, but as a separate line, not folded into your monthly net comparison. A higher employer pension contribution reduces your taxable income today (which is good for this month's net pay) while also building retirement savings you can't touch for decades (which doesn't help you pay rent next month). If you're comparing an offer with a 3% employer contribution against one with 8%, that 5-point gap is real money, it's just money that arrives in your sixties rather than your bank account this Friday. Decide how much weight that deserves based on your own timeline, not the recruiter's enthusiasm.
If one offer comes with 30% ruling eligibility and the other doesn't, that single factor can outweigh a meaningfully larger gross salary at the non-ruling employer. The ruling doesn't just shave a bit off your tax bill, it moves up to 30% of your salary outside the progressive brackets entirely, which is worth the most to people who'd otherwise sit in the 37.56% or 49.5% band on that portion of income. Two identical gross offers, one with the ruling and one without, can differ by several hundred euros a month in net pay. Before you compare anything else, confirm whether each employer can actually apply the ruling for your specific situation (recruited from abroad, distance requirement, salary threshold), since "we'll sort it out" from HR isn't the same as a signed application.
Run each offer through the income calculator separately, with its own gross salary, pension rate, holiday allowance percentage, and 30% ruling status set correctly. Write down the monthly net figure for each. Then, separately, list the benefits that don't show up in a net pay number: employer pension contribution as a yearly euro figure, the bijtelling-adjusted value of a company car, and anything else non-cash. Compare the net pay numbers first, since that's what actually changes your monthly life, then weigh the non-cash extras on top with their real, tax-adjusted value rather than their sticker price.
