Thinking about moving from the Netherlands to Italy and wondering how it will affect your taxes? You're not alone. Thousands of Dutch residents relocate to Italy each year, drawn by the Mediterranean lifestyle, lower cost of living in many regions, and — perhaps surprisingly — some genuinely attractive expat tax incentives. But the transition between two EU tax systems requires careful planning.

This comprehensive guide to expat tax Netherlands Italy planning walks you through residency rules, income tax rates, special regimes, double taxation treaty provisions, and the practical steps you need to take before, during, and after your move in the 2025/2026 tax year.

Understanding Tax Residency: When Do You Stop Being a Dutch Taxpayer?

The single most important question in any relocation tax planning exercise is: When does your tax residency change?

Dutch Tax Residency Rules

The Netherlands determines tax residency based on a facts-and-circumstances test. There is no single bright-line rule. The Dutch tax authorities (Belastingdienst) consider factors such as:

  • Where your permanent home is located — this carries the most weight
  • Where your family (spouse, children) resides
  • Where you are registered in the municipal personal records database (BRP)
  • Where you work and maintain social and economic ties
  • Your nationality (a secondary factor)

Simply deregistering from the BRP does not automatically end your Dutch tax residency. If you keep a home available in the Netherlands, maintain a Dutch bank account as your primary account, and your spouse remains in Amsterdam, the Belastingdienst may still treat you as a resident taxpayer — even if you spend most of the year in Rome.

Common mistake: Many expats assume that deregistering from the municipality is sufficient to end Dutch tax obligations. It is a necessary step, but not a sufficient one. You must genuinely sever your centre of life from the Netherlands.

Italian Tax Residency Rules

Italy considers you a tax resident if, for the greater part of the tax year (more than 183 days, or 184 in a leap year), you meet any one of these conditions:

  • You are registered in the Italian civil registry (Anagrafe della Popolazione Residente)
  • You have your habitual abode (domicilio) in Italy
  • You have your place of residence (residenza) in Italy

Starting from 2024 (and continuing into 2025/2026), Italy's revised residency rules — introduced by Legislative Decree 209/2023 — also added a fourth criterion: having your predominant presence in Italy for more than 183 days, counting partial days. This broadens the net considerably.

Once you are an Italian tax resident, you are taxed on your worldwide income, just as in the Netherlands.

Dutch Income Tax: What You Need to Know Before You Leave

Before departing, it's critical to understand your final Dutch tax obligations. Use our Netherlands Income Tax Calculator to model your departure-year liability.

The Split-Year Rule

The Netherlands does not formally apply a split-year rule for income tax purposes the way some countries do. In the year you emigrate, you are treated as a resident taxpayer until the date of departure and as a non-resident taxpayer for the remainder of the year. Your Box 1 income (employment, business, and home ownership) is taxed at the standard progressive rates up to your emigration date:

Taxable Income (2025) Rate
Up to €38,441 35.82%
€38,441 – €76,817 37.48%
Over €76,817 49.50%

Note: These rates include social security contributions in the first bracket for residents. The exact thresholds for 2025 may be adjusted slightly by the Dutch government; always verify with the latest published figures.

After your emigration date, the Netherlands can only tax income sourced from the Netherlands (e.g., Dutch rental property income, income from a Dutch business, or a Dutch pension under certain conditions).

The "Conserving Assessment" (Conserverende Aanslag)

If you have built up pension rights or hold a substantial interest (≥5%) in a Dutch BV (private limited company), the Belastingdienst may issue a conserving assessment upon emigration. This is essentially a conditional tax bill on:

  • Pension and annuity rights — calculated as if you received the entire value on the day of departure
  • Substantial interest gains — calculated on the unrealised capital gain in your shares

This assessment is deferred and only becomes payable if you take actions that trigger Dutch taxation (e.g., commuting your pension in a way not permitted under Dutch law). The Netherlands-Italy tax treaty provides specific rules on which country has taxing rights over pensions and capital gains, so professional advice is essential here.

Box 3: Savings and Investments

If you hold significant savings or investments, you will be subject to Box 3 taxation up to your departure date. The Netherlands has been reforming Box 3 following the landmark Kerstarrest Supreme Court ruling. For 2025, a modified system applies based on actual asset composition (savings, other investments, debts), with deemed returns applied to each category. Make sure you understand your Box 3 position before emigrating, as timing your departure can affect the amount of deemed income attributed to you.

Italian Income Tax: What Awaits You After Arrival

Once you become an Italian tax resident, you'll be subject to Italy's progressive income tax system (IRPEF). Use our Italy Income Tax Calculator to estimate your Italian tax burden.

IRPEF Rates for 2025

Italy's national income tax rates for 2025 are structured as follows:

Taxable Income Rate
Up to €28,000 23%
€28,001 – €50,000 35%
Over €50,000 43%

In addition to IRPEF, you'll also pay:

  • Regional surcharges (addizionale regionale): typically 1.23%–3.33%, depending on the region
  • Municipal surcharges (addizionale comunale): typically 0%–0.9%, depending on the municipality

So the effective marginal rate for high earners can exceed 47% when all surcharges are included.

Practical Example

If you earn €80,000 as a salaried employee in Italy in 2025, your approximate IRPEF calculation would be:

  1. First €28,000 × 23% = €6,440
  2. Next €22,000 (€28,001–€50,000) × 35% = €7,700
  3. Remaining €30,000 (€50,001–€80,000) × 43% = €12,900
  4. Total IRPEF: €27,040
  5. Plus regional/municipal surcharges: approximately €1,500–€2,500

This compares with a roughly similar overall burden in the Netherlands for the same salary, though the distribution across brackets differs. The key advantage for many expats lies in Italy's special regimes, discussed below.

Italy's Special Tax Regimes for Expats

Italy has introduced several incentive regimes designed to attract foreign talent and high-net-worth individuals. Understanding these is at the heart of effective relocation tax planning.

The "Impatriate" Regime (Regime Impatriati) — Post-2024 Rules

Italy's impatriate regime, significantly reformed by Legislative Decree 209/2023, offers a 50% exemption on employment and self-employment income for qualifying new residents, up to a cap of €600,000 per year. This effectively halves your tax rate on qualifying income.

To qualify under the 2025/2026 rules, you must:

  • Transfer your tax residence to Italy
  • Not have been an Italian tax resident for the three tax years preceding the transfer (or for a longer period under certain conditions)
  • Commit to remaining an Italian tax resident for at least four years
  • Perform most of your work in Italy
  • Possess high qualification or specialisation requirements, or meet specific conditions set by the employer

Key change from the old regime: The previous version offered a 70% (or even 90%) exemption and was more generous. The new rules are tighter but still represent a major tax saving. For someone earning €80,000, the taxable base drops to €40,000, resulting in IRPEF of roughly €9,640 — a saving of over €17,000 compared to standard taxation.

The benefit lasts for five years and can be extended for an additional three years (with a reduced 50% exemption) if you purchase a residential property in Italy or have dependent minor children.

The Flat Tax Regime for High-Net-Worth Individuals (Regime Forfettario per Neo-Residenti)

If you have significant foreign income (investments, rental income, business income abroad), Italy's flat tax regime for new residents (Article 24-bis TUIR) allows you to pay a lump-sum tax of €200,000 per year on all foreign-source income, regardless of the amount. Family members can be included for an additional €25,000 each.

Eligibility requirements:

  • You must not have been an Italian tax resident for at least nine of the ten tax years preceding your transfer
  • You must file an advance ruling or elect the regime in your Italian tax return

This regime is particularly attractive for individuals with very high foreign income — for example, someone receiving €1 million annually in foreign dividends and rental income would pay just €200,000 in Italian tax on that income, rather than potentially over €400,000 under the standard IRPEF system.

Note: Italian-source income is still taxed under normal IRPEF rules.

The Netherlands–Italy Double Taxation Treaty

The Netherlands and Italy have a double taxation agreement (DTA) that prevents you from being taxed twice on the same income. This treaty, based largely on the OECD Model Convention, covers the following key income types:

Employment Income (Article 15)

Employment income is generally taxable only in the country where the work is physically performed. If you move to Italy and work for an Italian employer (or remotely for a Dutch employer while physically in Italy), Italy has the primary taxing right. The Netherlands would not tax this income, provided you are no longer a Dutch resident.

However, if you continue working partly in the Netherlands (e.g., commuting to a Dutch office), the Netherlands retains the right to tax the income attributable to workdays in the Netherlands.

Pensions (Article 18)

Under the Netherlands-Italy treaty:

  • Private pensions are generally taxable only in the country of residence (Italy, after your move)
  • Government pensions (e.g., ABP pensions for former Dutch civil servants) are taxable in the Netherlands, unless you are an Italian national
  • Social security pensions (AOW) — the treaty assigns taxing rights to the paying state (Netherlands) in most cases

This is a nuanced area. The interaction between the treaty, Dutch domestic law, and Italian domestic law requires careful analysis, especially if you receive multiple types of pension income.

Capital Gains and Substantial Interest (Article 13)

Capital gains on shares are generally taxable in the state of residence. However, gains on immovable property are taxable where the property is located. If you hold a substantial interest in a Dutch BV, the conserving assessment (described above) may apply, and the treaty's provisions must be carefully reviewed.

Dividends, Interest, and Royalties

The treaty provides for reduced withholding tax rates:

  • Dividends: 15% (or 5% for substantial participations of ≥25%)
  • Interest: 10%
  • Royalties: 5%

Italy will grant a tax credit for any Dutch withholding tax paid, preventing double taxation.

Step-by-Step Relocation Tax Checklist

To ensure a smooth transition from the Netherlands to Italy, follow these practical steps:

  1. Determine your move date carefully — timing affects which country taxes your income for the year and whether you qualify for Italy's special regimes
  2. Deregister from the Dutch BRP — notify your municipality of your departure and provide your new Italian address
  3. Register with the Italian Anagrafe — register as a resident in your new Italian municipality within 20 days of arrival
  4. Apply for an Italian fiscal code (codice fiscale) — you'll need this before you can open a bank account, sign a lease, or file taxes
  5. Notify your Dutch employer or pension provider — they need to adjust withholding and potentially stop Dutch payroll tax deductions
  6. File a Dutch departure-year tax return (M-biljet) — this special return covers both the resident and non-resident periods
  7. Evaluate eligibility for Italian special regimes — consult a tax advisor to determine whether the impatriate regime or flat tax regime applies to you
  8. Review your investment and pension structure — ensure your Dutch pension, Box 3 investments, and any BV holdings are optimally structured under the treaty
  9. File your first Italian tax return — the Italian tax year runs January 1–December 31, with the annual return (Modello Redditi) due by November 30 of the following year
  10. Keep records of your physical presence — track days spent in Italy and abroad to support your residency position in both countries

Frequently Asked Questions

Can I be a tax resident in both the Netherlands and Italy at the same time?

Yes, it's possible under each country's domestic law. However, the Netherlands-Italy tax treaty contains tie-breaker rules (Article 4) that assign residency to one country based on: permanent home, centre of vital interests, habitual abode, and finally nationality. In practice, if you've genuinely relocated your life to Italy, the treaty will typically resolve the conflict in Italy's favour.

Will I lose my 30% ruling if I leave the Netherlands?

Yes. The 30% ruling (a Dutch tax benefit for inbound expats) ends when you cease to be employed by a Dutch employer or leave the Netherlands. It cannot be "paused" and resumed. If you later return to the Netherlands, you may need to apply for a new ruling, subject to the current eligibility requirements.

Is Italy really cheaper from a tax perspective?

It depends entirely on your income profile. For standard employment income without special regimes, the effective tax burden in Italy and the Netherlands is broadly similar. However, Italy's impatriate regime can slash your effective rate dramatically, and the flat tax regime is unbeatable for high-net-worth individuals with significant foreign income. Use our Italy Income Tax Calculator and Netherlands Income Tax Calculator to compare scenarios.

What about healthcare and social security contributions?

Once you become an Italian resident, you will typically enrol in Italy's national health service (SSN). Social security contributions in Italy are split between employer and employee, with employee contributions generally around 9%–10% of gross salary. The EU social security coordination regulations (EC 883/2004) ensure you don't pay double contributions during the transition period.

Do I need to report my Dutch bank accounts to Italy?

Yes. Italian tax residents must disclose all foreign financial assets in the Quadro RW section of their tax return. This includes Dutch bank accounts, brokerage accounts, real estate, and other foreign assets. Failure to report can result in significant penalties. Additionally, the IVAFE (a 0.2% annual tax on foreign financial assets) and IVIE (a tax on foreign real estate) may apply.

Conclusion: Plan Early, Save Significantly

Relocating from the Netherlands to Italy can be a financially rewarding move — but only if you plan ahead. The difference between a well-structured relocation and a poorly planned one can easily amount to tens of thousands of euros in unnecessary taxes.

Here are your key takeaways:

  • Genuinely sever your Dutch tax residency by relocating your home, family, and centre of life to Italy — not just your registration
  • Explore Italy's special tax regimes — the impatriate regime and flat tax regime offer substantial savings for qualifying expats
  • Understand the double taxation treaty — it protects you from being taxed twice but requires careful application to pensions, investments, and capital gains
  • File correctly in both countries — the Dutch M-biljet and Italian Modello Redditi are both required in your transition year
  • Seek professional advice — the interaction between Dutch exit taxation, Italian entry incentives, and treaty provisions is complex
