If you employ even one expat, the 30%-regeling is not a “tax topic” it’s a cash-flow topic. It changes what people take home, what you need to budget, how you word contracts, and how quickly a small misunderstanding can become a trust issue. In 2026 the headline stays steady at 30%, but the edges tighten in ways that show up right where small businesses feel it: invoices, payroll runs, and negotiations at the kitchen-table level.

Here’s the plain version. To use the 30% ruling, your employee must earn at least a minimum annual salary. In 2026 that threshold rises to €48,013 for most cases, and to €36,497 for employees under 30 with a master’s degree. That matters because one euro under the line can mean the ruling doesn’t apply at all. For a micro-employer, that’s not a theoretical risk; it’s the difference between an offer that works for a candidate and one that suddenly doesn’t, after you’ve already invested time, onboarding, and goodwill.

Then there’s the salary cap, now unavoidable. The 30% ruling only applies up to a maximum salary linked to the WNT-plafond (the public-sector top-income standard). In 2026 that cap is €262,000, and crucially, the transition rules have fully ended as of 1 January 2026, so the cap now applies to everyone using the ruling. Most small firms won’t pay near that ceiling, but the lesson is still relevant: the government is narrowing the space where “special arrangements” live. If you’re hiring senior talent, you can’t rely on old exceptions or assume someone else’s arrangement will carry over.

Small but irritating changes also land in daily admin. A few “extraterritorial costs” that could be reimbursed tax-free, think utilities and private phone costs, drop out of the untaxed category. That doesn’t mean you can’t reimburse them; it means they’re more likely to be treated as taxable wage, which creates extra payroll handling and uncomfortable conversations if expectations were set differently. One concrete example I’ve seen too often: a small consultancy agrees on a clean net salary expectation with a new hire, but the contract is vague about which reimbursements are tax-free. A month later the payroll slip surprises them, and suddenly the issue isn’t money, it’s confidence.

And the horizon matters. In 2027, the percentage itself is planned to fall to 27%, reducing the advantage further. For employees already on the 30% ruling before 1 January 2024, the 30% percentage can still run until the end of their eligible period, which helps with retention planning, but it also creates a split workforce where “same role” doesn’t mean “same net pay.” That’s where resentment and confusion can quietly grow unless you explain it early, calmly, and in writing.

The steady way through this is not panic; it’s precision. Tighten your employment contracts so the 30%-regeling is described as conditional, not promised, and make the salary thresholds and reimbursements explicit enough that payroll won’t have to improvise. Build a habit of checking the minimum salary requirement before you sign, not after you celebrate. And for 2027, treat the planned drop to 27% as a negotiation input now, so you’re not renegotiating under pressure later. Small businesses don’t need more noise; they need fewer surprises. The 30% ruling is still useful in 2026, but it rewards clarity. In a year where “unchanged” hides several shifts, clarity is the cheapest form of risk control you have.
