2026 Box 1 tax year
35.75% up to €38,883. 37.56% up to €78,426. 49.50% above. The 30% ruling excludes part of your salary from Box 1 entirely.
Which year of your 5-year ruling term?
The 2024 plan to step the ruling down to 20% then 10% was reversed — for 2026 it stays a flat 30% tax-free for the full 5-year term, whichever year you're in.

Don't forget vakantiegeld (holiday allowance)
Dutch employers must pay at least 8% of your gross salary as holiday allowance — usually €7,200/year on this salary, paid as a lump sum around May. Many job ads quote gross pay excluding this, so check whether the figure you were offered already includes it.
| Gross salary | €90,000 |

| Net take-home (annual) | €67,041 |
Calculations use 2026 Box 1 rates (35.75% / 37.56% / 49.50%) and assume standard working-age employment. The 30% ruling is modelled as a flat 30% tax-free allowance for the full 5-year term (the previously legislated 30-20-10 step-down was reversed for 2026); it drops to a flat 27% from 2027 onward, which this calculator does not model. Eligibility for the ruling (recruitment from abroad, specific-expertise salary threshold, prior residency distance test) is not verified by this tool. Does not account for the general tax credit, employment tax credit, health insurance premium (ZVW), pension contributions, or Box 2/3 income. For precise advice consult a Dutch tax adviser or the Belastingdienst.
