Portugal vs Netherlands: The Personal Tax Reality Check for Founders and Senior Executives

The European Tax League — Edition 1 | expatico.eu

The headline number nobody talks about

49.5%. That's the top personal income tax rate in the Netherlands. For years, Amsterdam and Rotterdam were the default European base for international startups and their senior teams. Great cities, strong ecosystems, English-speaking — and the 30 Ruling to soften the tax blow.

That advantage is quietly disappearing.

Meanwhile, Portugal has built one of the most aggressive personal tax regimes in Europe for relocating talent. If you're a founder, CTO, or senior executive deciding where to base yourself in Europe — the math has shifted.

What is the 30 Ruling?

The 30 Ruling (officially the 30%-regeling) is a Dutch tax incentive for employees recruited from abroad. It allows qualifying individuals to receive 30% of their salary tax-free, effectively reducing their taxable income significantly.

For years it was a genuine advantage. But the Dutch government has been chipping away at it:

• Salary cap: The 30% benefit now applies only up to a capped salary base (approximately €233,000, index-linked and subject to annual revision). Income above that threshold is taxed at full Dutch progressive rates.

• Duration cut: The regime now runs for 5 years, down from the original 8.

• Annual budget pressure: Every Dutch budget cycle since 2023 has included further restrictions, including a phased reduction of the 30% rate in some reform scenarios.

For a senior executive on a €500K salary, the 30 Ruling only applies to the first €233K. Everything above that is taxed at full Dutch rates from day one.

What is IFICI?

IFICI — the Incentivo Fiscal à Investigação Científica e Inovação — is Portugal's successor to the NHR (Non-Habitual Resident) regime. For qualifying individuals, it offers:

• 20% flat income tax on qualifying employment and self-employment income from eligible activities

• Exemptions on qualifying foreign income categories (dividends, interest, certain capital gains) — subject to your income structure, applicable tax treaties, and anti-abuse rules

• No salary cap on the 20% rate — the flat rate applies regardless of income level, for qualifying income

• 10 years — double the duration of the 30 Ruling

• Generally not employer-tied — though significant changes in role or sector may require reassessment of eligibility

Eligibility requires not having been a Portuguese tax resident in the previous 5 years, and working in a qualifying activity — which includes technology, R&D, senior management in specific sectors, and others. The regime is designed for a defined set of high-skill profiles, not all professions.

The numbers on a €500K salary

These figures are illustrative, based on qualifying employment income under standard assumptions. Individual outcomes depend on income structure, personal circumstances, and applicable tax rules.

Netherlands — 30 Ruling active (years 1-5):

The 30 Ruling applies only to the capped salary base (~€233K). The remaining €267K is taxed at full Dutch progressive rates, with the top bracket at 49.5%. On a blended basis, the effective rate on €500K with the 30 Ruling active is approximately 43-44%.

Illustrative take-home: ~€280K-€290K per year

Netherlands — 30 Ruling expired (year 6 onwards):

Once the 30 Ruling expires, there is no relief. The full €500K is taxed at progressive Dutch rates.

Illustrative take-home: ~€264K per year

Portugal — IFICI (all 10 years):

20% flat on qualifying Portuguese source employment income. Certain foreign income categories may be exempt subject to structure and treaty conditions.

Illustrative take-home: ~€400K per year on qualifying employment income

The illustrative gap: up to ~€136K per year in favour of Portugal — from year 1, on qualifying income under standard assumptions.

Beyond the tax rate: what else changes?

Personal income tax is only part of the picture. Here's what else shifts when you compare Amsterdam and Lisbon as a base:

• Average senior engineer salary — Amsterdam: ~€85,000 · Lisbon: ~€47,000

• Office space (per m² per month) — Amsterdam: €35-45 · Lisbon: €18-25

• Cost of living index — Amsterdam: High · Lisbon: Medium

• R&D tax credit — Netherlands: ~23% (WBSO) · Portugal: up to 82.5% (SIFIDE)

• EU entity — Both: ✅

• English-speaking ecosystem — Both: ✅

The salary differential alone is significant. If you're building an R&D team of 10 engineers, the difference between Amsterdam and Lisbon salary costs is approximately €380,000 per year — before factoring in R&D tax credits.

The verdict

The Netherlands is a great place to build a startup. The ecosystem is strong, the talent is excellent, and Amsterdam remains one of Europe's most liveable cities for international professionals.

But the 30 Ruling — the regime that made the Dutch personal tax picture bearable for high earners — is being steadily dismantled. It's capped, shortened, and under pressure every budget cycle.

Portugal's IFICI was built for a different era: the era of mobile, high-earning founders and executives who choose where to base themselves based on data, not default.

For those who qualify and structure correctly, Portugal wins this one — by a significant margin.

Is IFICI right for you?

IFICI eligibility depends on your professional profile, residency history, income structure, and qualifying activity. The regime is powerful — but it requires proper setup to access the full benefit, and the rules around foreign income exemptions are nuanced and fact-specific.

At Expatico, we help founders and senior hires assess whether they qualify, structure their move to Portugal correctly, and access the full range of Portuguese incentives — from IFICI applications and company incorporation to talent sourcing and grant access.
