The Netherlands has long been one of Europe's most internationally minded economies. Amsterdam's position as a global financial hub, the presence of a large multinational corporate base, and a long tradition of English-language proficiency have made it a natural destination for British expats and internationally mobile professionals. The famous 30% ruling adds a specific financial incentive for qualifying high earners. This guide sets out the key financial planning considerations for British nationals and international HNW clients relocating to or investing in the Netherlands.
Dutch Tax Residency
The Netherlands taxes worldwide income for tax residents. Residency is determined by facts and circumstances rather than a simple day count — the key question is where your personal and economic life is centred. The Dutch tax authority (Belastingdienst) applies a substance-over-form approach: maintaining a home, holding a Dutch employment contract, or having family in the Netherlands will typically establish residency regardless of formal notification.
Upon arrival, individuals register with the municipality (gemeente), which automatically triggers registration with the tax authorities and the issuance of a Burgerservicenummer (BSN — the Dutch equivalent of a National Insurance number). Tax residency is usually established from the date of registration.
The 30% Ruling: The Key Expat Benefit
The 30% ruling (30%-regeling) is the centrepiece of the Dutch expat tax framework and one of the most generous employer-sponsored tax concessions in Europe.
How it works: qualifying employees can receive 30% of their total gross salary as a tax-free allowance, intended to compensate for extraterritorial costs (international schooling, relocation, housing costs). The effect is that only 70% of gross salary is subject to Dutch income tax. For a gross salary of €150,000, this means €45,000 is tax-free, reducing the taxable base to €105,000.
Qualifying criteria:
- Recruited or transferred from abroad (not already living in the Netherlands)
- Not resident within 150km of the Dutch border in the 24 months before the employment began (this is a hard geographic rule that catches some candidates who have lived in Belgium or Germany)
- Earning above the minimum salary threshold (approximately €46,000 for most employees; lower for researchers and scientific workers)
Duration: as of 2024, the ruling lasts for a maximum of five years, reduced from eight years in earlier legislation. A partial grandfathering arrangement applies for those who entered under the old rules. The tax-free percentage remains 30% for 2024 to 2026; from 1 January 2027 it falls to a flat 27% for the full five-year period.
Partial non-resident taxpayer status (now abolished): until the end of 2024, employees benefiting from the 30% ruling could elect to be treated as a partial non-resident taxpayer for Box 2 (substantial interests) and Box 3 (savings and investments) purposes, meaning these were taxed only on Dutch-sited assets. This election was abolished from 1 January 2025 (with limited transitional protection to the end of 2026 for those already using the 30% ruling before 2024). New arrivals can no longer rely on it, so offshore investment portfolios will generally fall fully within the Dutch Box 3 regime once the holder is Dutch tax resident.
Dutch Income Tax: The Box System
Dutch income tax operates through three separate "boxes":
Box 1 — Income from work and home: taxed on a progressive scale. In 2024, income up to approximately €75,624 is taxed at 36.97%; income above this threshold is taxed at 49.5%. The eigenwoningforfait — a deemed rental income on your primary residence — is also included in Box 1 and is a quirk of the Dutch system that many British expats find counterintuitive.
Box 2 — Substantial interest in companies: applies where an individual holds 5% or more of shares in a company. Rates were increased significantly in 2024 (24.5% on the first €67,000 of income; 33% above that). This affects business owners and those with significant shareholdings.
Box 3 — Savings and investments: this is the most unusual and legally contested element of Dutch taxation. Rather than taxing actual investment returns, Box 3 applies a deemed return model — the tax authority assumes your portfolio achieves a blended return (currently calculated based on a notional allocation between cash, other investments, and property), and levies 36% on that deemed return.
This system has faced significant legal challenges. The Dutch Supreme Court ruled in 2021 that Box 3 violated Article 1 of Protocol 1 (protection of property) and Article 14 (non-discrimination) of the European Convention on Human Rights, particularly in years where actual returns fell below the deemed return. The government has been paying partial compensation to affected taxpayers and is legislating a new actual-return system, though this has been repeatedly delayed. The current rules remain in force during the transition period — professional advice is essential.
UK Pensions in the Netherlands
Under the UK-Netherlands Double Tax Treaty, pension income from private and occupational UK schemes is generally taxed in the Netherlands (the state of residence). This means:
- Apply for an HMRC No Tax (NT) code to prevent UK withholding tax deduction at source.
- Dutch income tax applies at Box 1 rates to pension income received in the Netherlands.
- Government and civil service pensions (teachers, NHS, armed forces, civil service) are taxed in the UK only under the treaty's government service provision.
Employees working in the Netherlands contribute to the Dutch state pension system (AOW — Algemene Ouderdomswet) through social insurance contributions. An AOW entitlement accrues at 2% per year of Dutch residence between ages 15 and 66 (rising to 67). Expats on short assignments who leave before full entitlement accrues receive a proportional benefit. The AOW can be claimed from outside the Netherlands in retirement.
Capital Gains and the Dutch Property Market
The Netherlands does not have a traditional capital gains tax for private investors on shares, bonds, or funds. Instead, Box 3's deemed return system replaces what would otherwise be a CGT charge. This means that a private investor who realises a large capital gain on a share portfolio does not pay tax on the gain itself — the tax is calculated on the notional return on the portfolio value each year.
For property: the principal private residence falls in Box 1 (with an eigenwoningforfait deemed benefit in kind); investment properties fall in Box 3. There is no equivalent of the UK's 28% CGT rate on residential property sales.
The Amsterdam and broader Dutch residential property market is among the most expensive in Europe, driven by chronic housing supply shortages. Foreign nationals — including British citizens post-Brexit — can purchase property freely. Purchase costs include transfer tax (overdrachtsbelasting) of 10.4% for investment properties (2% for primary residences in 2024, subject to conditions), notary fees, and valuation costs.
Dutch Inheritance Tax: Erfbelasting
Dutch inheritance tax is levied at rates of 10–40% depending on the relationship between deceased and beneficiary and the value received. Key exemptions in 2024:
- Spouse or registered partner: exempt up to approximately €800,000 (with specific rules on pension rights)
- Children: €24,676 (lower rate of 10–20%)
- Other individuals (siblings, friends, unrelated parties): €2,658 (higher rates of 30–40%)
Dutch inheritance tax applies to the worldwide assets of Dutch-resident deceased persons, and also to Dutch-sited assets (including Dutch real estate) for non-residents. For clients with both UK and Dutch assets who are Dutch tax resident, cross-border double taxation can arise — where both UK IHT and Dutch erfbelasting may apply to the same assets. The UK-Netherlands Double Tax Treaty does not contain a comprehensive inheritance tax treaty, and coordination of both regimes requires specialist advice.
Practical Steps for Netherlands-Bound Clients
- Establish offshore investment bonds and tax-efficient wrappers before establishing Dutch tax residency — note that the partial non-resident taxpayer election was abolished from 1 January 2025, so pre-arrival structuring is now more important than ever.
- Ensure the 30% ruling application is submitted within four months of starting employment — missing this deadline is irrecoverable.
- Apply for an NT code from HMRC once Dutch residency is confirmed.
- Monitor Box 3 reform developments and ensure your adviser is tracking the legislative changes.
- For significant investment portfolios, obtain qualified Dutch tax advice on the interaction of actual returns and the current deemed-return system.
- Review estate planning structures with advisers in both the UK and the Netherlands.
Tax rules, rates, and legislation can change. This guide reflects the position as of mid-2026 and should not be treated as tax advice. The value of investments can fall as well as rise. Clients should obtain qualified professional advice before making decisions.

Frequently Asked Questions
What is the Dutch 30% ruling?
The 30% ruling is a tax concession available to qualifying high-skilled migrants recruited from abroad. Eligible employees can receive 30% of their gross salary as a tax-free allowance for up to five years, significantly reducing their effective Dutch income tax rate. To qualify, the employee must have been recruited from outside the Netherlands, must not have lived within 150km of the Dutch border in the 24 months before starting the role, and must earn above a minimum salary threshold (approximately €46,000 gross in 2024, adjusted annually). The ruling is applied by the employer and must be requested jointly with the employee within four months of starting employment.
How does Box 3 tax savings and investments?
Box 3 taxes savings and investments based on a deemed return rather than actual return. The Dutch tax authorities assume that your portfolio generates a certain percentage return each year (currently a blended rate based on assumed allocations to cash, bonds, and equities), and you are taxed on that deemed return at 36% regardless of what the assets actually earned. Dutch courts have found this system violated the European Convention on Human Rights for low-yield periods. Significant reform is ongoing, with a move towards taxing actual returns expected, though implementation has been repeatedly delayed.
Are there inheritance taxes in the Netherlands?
Yes. Dutch erfbelasting applies to inheritances and gifts received by Dutch residents and to Dutch-sited assets for non-residents. Rates depend on the relationship: spouses and registered partners benefit from an exemption of over €800,000 at the lower rate bands; children face rates of 10–20% above their exemption of approximately €24,000; unrelated beneficiaries face rates of 30–40%. For clients with significant assets, cross-border estate planning — particularly where both Dutch and UK inheritance taxes may apply — is essential.
Can I transfer my UK pension to the Netherlands?
UK registered pension schemes cannot be transferred to a Dutch pension provider in a tax-free QROPS transfer because the Netherlands is not generally on the HMRC QROPS list of qualifying schemes. Most British expats in the Netherlands retain their UK pension and draw it in the Netherlands, where it is taxed as Dutch income under the treaty. An NT code from HMRC removes UK withholding tax on the income.
What happens to the 30% ruling if I change jobs?
The 30% ruling is attached to a specific employment relationship. If you change employers, your new employer must apply for the ruling within four months of your start date to keep continuity (and the gap between jobs must generally not exceed three months). If that window is missed, the ruling is lost and cannot be reinstated. The five-year clock continues from when the original ruling began — it does not reset with a new employer. Gaps in employment can also interrupt the ruling, so careful planning around job changes is important.
