Expat Tax Planning: Relocating from Spain to Italy in 2025 – What You Need to Know

If you're considering moving from Spain to Italy, understanding the tax implications is one of the most important steps in your relocation planning. Expat tax between Spain and Italy can be complex — both countries have progressive income tax systems, specific residency rules, and overlapping obligations that can catch the unprepared off guard. Proper expat tax Spain Italy planning can save you thousands of euros and prevent costly compliance errors.

In this comprehensive guide, we break down everything you need to know about relocation tax planning when leaving Spain and establishing your new life in Italy for the 2025/2026 tax year. From exit taxes and residency triggers to Italy's attractive flat-tax regime for new residents, we cover the actionable details you need to make informed decisions.

Understanding Tax Residency: When Does Spain Let Go and Italy Take Over?

The single most critical question in any international relocation is: where are you considered a tax resident? Getting this wrong can mean you're taxed as a resident in both countries simultaneously — or, worse, that you fail to file in one country and face penalties.

Spain's Tax Residency Rules

Under Spanish law (Ley del IRPF), you are considered a tax resident of Spain if any of the following apply:

You spend more than 183 days in Spain during a calendar year (January 1 – December 31).
Spain is the center of your economic interests — meaning the base or source of your main income or assets is in Spain.
Your spouse and/or dependent minor children reside in Spain (unless you can prove otherwise).

Spain uses the calendar year as its tax period. If you leave Spain on June 15, 2025, you will have spent fewer than 183 days in Spain that year and can generally claim non-residency for the full 2025 tax year — provided your economic center and family have also moved.

Italy's 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 Anagrafe della Popolazione Residente (Registry of Resident Population).
You have your habitual abode (domicilio) in Italy.
You have your domicile — meaning the center of your personal and economic relations — in Italy.

As of 2024 reforms (effective for 2025), Italy updated its definition of tax residence to align more closely with OECD standards, emphasizing the concept of "domicile" as the place of predominant personal and family relations. This is an important nuance for expats.

Key takeaway: Plan your move so that you clearly break Spanish tax residency in the calendar year of departure while establishing Italian residency. The timing of your physical move, family relocation, and administrative registrations all matter.

Leaving Spain: Exit Obligations and the "Exit Tax"

Spain doesn't simply let you walk away. There are several tax obligations you must address when you leave.

The Spanish Exit Tax (Impuesto de Salida)

Spain imposes an exit tax on individuals who have been tax residents for at least 10 of the last 15 years and who hold certain qualifying assets. This applies if you own:

Shares or participations in any entity with a total market value exceeding €4 million, or
Shares representing a participation of at least 25% in an entity with a market value exceeding €1 million.

If triggered, you are deemed to have disposed of these assets on the last day of your Spanish tax residency and must pay tax on the unrealized capital gains at Spain's savings tax rates:

Capital Gains Bracket (2025)	Tax Rate
First €6,000	19%
€6,001 – €50,000	21%
€50,001 – €200,000	23%
€200,001 – €300,000	27%
Over €300,000	28%

Since you're relocating to another EU member state (Italy), you can request a deferral of the exit tax payment until the shares are actually sold. However, you must provide a guarantee or comply with reporting requirements.

Final Spanish Tax Return

You'll need to file a final Spanish income tax return (Modelo 100) for the year of departure, generally due between April and June of the following year. This return covers your worldwide income for the period you were a Spanish resident, plus any Spanish-source income earned after you became a non-resident.

Other Departure Formalities

Notify the Agencia Tributaria of your change of address/residence status using Modelo 030.
Deregister from the Padrón Municipal (town hall census).
Consider the implications for Modelo 720 (overseas asset reporting). If you've been filing this form, your final obligation arises for the tax year in which you were last a Spanish resident.
Review any autonomous community taxes (e.g., wealth tax, solidarity tax) that may apply up to the date of departure.

Arriving in Italy: Income Tax Framework for 2025/2026

Once you establish Italian tax residency, Italy will tax you on your worldwide income. Italy's personal income tax, known as IRPEF (Imposta sul Reddito delle Persone Fisiche), is progressive with the following national brackets for 2025:

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

In addition to national IRPEF, you'll pay:

Regional surcharge (addizionale regionale): typically 1.23% to 3.33%, depending on the region.
Municipal surcharge (addizionale comunale): typically 0% to 0.9%, depending on the municipality.

This means your effective marginal tax rate can exceed 47% at the highest bracket.

Practical Example

Suppose you earn €80,000 annually as an employed expat in Italy:

First €28,000 taxed at 23% = €6,440
Next €22,000 (€28,001 – €50,000) taxed at 35% = €7,700
Remaining €30,000 (€50,001 – €80,000) taxed at 43% = €12,900
Total national IRPEF = €27,040
Add approximately 2% regional + 0.5% municipal surcharges on taxable income = ~€2,000
Approximate total income tax ≈ €29,040, for an effective rate of about 36.3%.

Italy's Special Tax Regimes for New Residents

One of the most compelling reasons for relocation tax planning to Italy is the availability of preferential tax regimes. These can dramatically reduce your tax burden in the early years.

The Impatriate Regime (Regime Impatriati) – Updated Rules

Italy offers a special regime for workers who transfer their tax residence to Italy. Following reforms that took effect from January 1, 2024 (and continuing into 2025), the updated rules provide:

A 50% exemption on qualifying employment and self-employment income, up to a cap of €600,000 per year.
Available for 5 tax years (no longer extendable to 10 years as under the old regime).
The exemption increases to 60% if you move with a minor child or adopt a child during the benefit period.

Eligibility requirements:

You must not have been an Italian tax resident for at least 3 tax years prior to the transfer (6 years if you previously worked for the same employer/group).
You commit to remaining an Italian tax resident for at least 4 years (or you must repay the benefits).
You must possess high qualifications or be in a managerial/specialized role, OR the employer must be different from the one you had abroad.

This means if you've been living and working in Spain for the past 3+ years and move to Italy for a new or qualifying role, you could pay Italian income tax on only 50% of your salary. On an €80,000 salary, that could reduce your IRPEF base to €40,000, cutting your national tax from approximately €27,040 to around €14,140 — a saving of nearly €13,000 per year.

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

If you have significant income from foreign sources, Italy offers a flat tax of €200,000 per year on all foreign-sourced income, regardless of the amount. Key features include:

Available to individuals who have not been Italian tax residents for at least 9 of the previous 10 tax years.
Covers all foreign income — dividends, rental income, capital gains, interest, etc.
Italian-source income is taxed normally under IRPEF.
Family members can join the regime for an additional €25,000 per person per year.
Available for up to 15 years.
Individuals under this regime are exempt from Italian foreign asset reporting (RW form) and from inheritance/gift tax on foreign assets.

This regime is particularly attractive for entrepreneurs, investors, and retirees with substantial non-Italian income streams.

The 7% Flat Tax for Pensioners

If you're a retiree receiving a foreign pension and move to a qualifying municipality in Southern Italy (regions including Sicily, Sardinia, Calabria, Campania, Basilicata, Puglia, Abruzzo, or Molise) with a population of fewer than 20,000 inhabitants, you may qualify for a 7% flat tax on all foreign-source income for 10 years.

This is a remarkably favorable rate compared to Spain's progressive rates for pension income, which can reach up to 47% (or higher in certain autonomous communities).

The Spain-Italy Double Taxation Treaty

Spain and Italy have a bilateral double taxation agreement (DTA) that follows the OECD Model Convention. This treaty is essential for avoiding being taxed twice on the same income during your transition year and beyond.

Key Provisions

Employment income is generally taxable in the country where the work is performed (Article 15). If you work part of the year in Spain and part in Italy, each country can tax the income attributable to work performed on its territory.
Pension income from private sources is typically taxable only in the country of residence (Italy, once you move). Government pensions are usually taxable only in the source country (Spain for Spanish government pensions).
Dividends, interest, and royalties may be subject to withholding tax in the source country, but at reduced treaty rates (typically 15% for dividends, 12% for interest).
Capital gains on shares are generally taxable only in the country of residence, with exceptions for real property.
Real estate income (rental income from property in Spain) remains taxable in Spain, but Italy must grant a credit for Spanish tax paid.

Claiming Relief

In practice, Italy provides relief via a foreign tax credit (credito d'imposta). If you pay tax on Spanish-source income, you can credit that tax against your Italian IRPEF liability on the same income. The credit cannot exceed the Italian tax attributable to that foreign income.

To claim this credit, you must:

Declare the foreign income on your Italian tax return (Modello 730 or Modello Redditi PF).
Provide documentation of the foreign tax paid.
Ensure the income has been declared as "definitive" (definitivamente tassato) in Spain.

Common Mistakes and Misconceptions When Moving from Spain to Italy

Relocating between two EU countries may seem straightforward, but expat tax Spain Italy transitions are full of pitfalls. Here are the most common mistakes:

1. Assuming the Move Date Equals the Tax Residency Date

Tax residency doesn't flip like a switch on your moving day. Spain uses a 183-day rule across the full calendar year, and Italy looks at the greater part of the year. You could physically move in March but still be treated as a Spanish resident for the entire year if your spouse and children remain in Spain.

2. Failing to Deregister Properly in Spain

If you remain on the Padrón Municipal or continue to appear as resident for administrative purposes, Spanish tax authorities may argue you never left. Formally deregistering is essential.

3. Not Registering with the Anagrafe in Italy

Conversely, failing to register in Italy's population registry can delay your eligibility for favorable regimes (like the impatriate regime) and create gaps in your tax history.

4. Overlooking the Modelo 720

Spain's overseas asset declaration (Modelo 720) has been the subject of EU Court rulings striking down its disproportionate penalties, but the reporting obligation itself still exists. Make sure your final filing is complete.

5. Missing the Window for Italy's Special Regimes

The impatriate regime must generally be elected in your first Italian tax return or through a written agreement with your employer. Missing this deadline can mean losing five years of 50% income exemptions.

6. Ignoring Regional and Municipal Taxes in Italy

Many expats focus only on national IRPEF rates and forget that regional and municipal surcharges can add 2–4 percentage points to the effective rate. Factor these into your planning.

Step-by-Step Relocation Tax Checklist

To help you stay organized, follow this action plan:

6–12 months before moving: Consult a cross-border tax advisor familiar with both Spanish and Italian tax law. Review your asset portfolio for exit tax exposure.
3–6 months before: Evaluate eligibility for Italy's special tax regimes (impatriate, flat tax, pensioner regime). Gather documentation of your non-Italian residency history.
Upon departure from Spain: Deregister from the Padrón Municipal. Notify the Agencia Tributaria (Modelo 030). Close or restructure Spanish bank accounts and investments as needed.
Upon arrival in Italy: Register at the Anagrafe della Popolazione Residente. Obtain your codice fiscale (Italian tax ID) if you don't already have one. Notify your employer and elect the impatriate regime if applicable.
Within the first tax filing period: File your final Spanish tax return (Modelo 100) by June 30, 2026, for the 2025 tax year. File your first Italian tax return (Modello Redditi PF) by November 30, 2026, for the 2025 tax year. Claim foreign tax credits for any double-taxed income.
Ongoing: Continue filing in Italy on your worldwide income. Monitor Spanish obligations for any continuing Spanish-source income (e.g., rental property, pensions). Reassess your status annually.

Frequently Asked Questions

Can I be a tax resident of both Spain and Italy at the same time?

Technically, under each country's domestic law, yes — it's possible to meet both countries' residency tests simultaneously. In that case, the Spain-Italy Double Taxation Treaty's tie-breaker rules determine your single treaty residence based on (in order): permanent home, center of vital interests, habitual abode, and nationality.

Will I pay the Spanish exit tax if I only own a stock portfolio worth €200,000?

No. The exit tax only applies if your qualifying shareholdings exceed €4 million in total value or represent 25%+ of an entity worth over €1 million. Standard investment portfolios are typically unaffected.

How long do I need to stay in Italy to keep the impatriate regime benefits?

You must remain an Italian tax resident for at least 4 consecutive years after electing the regime. If you leave earlier, you must repay the tax savings plus interest.

Is my Spanish rental income taxable in Italy?

Yes. As an Italian tax resident, you must declare worldwide income, including Spanish rental income. However, you'll receive a foreign tax credit in Italy for the Spanish tax paid on that rental income, so you won't be taxed twice.

When should I make the move for optimal tax planning?

In most cases, moving in the first half of the calendar year (ideally before July 2) allows you to clearly break Spanish tax residency for that year (fewer than 183 days in Spain) while simultaneously establishing Italian residency for the greater part of the year. This creates a clean transition with no overlap.

Conclusion: Plan Early, Save Significantly

Relocating from Spain to Italy in 2025 presents both challenges and remarkable opportunities from a tax perspective. Spain's exit obligations must be handled carefully, but Italy's generous regimes for new residents — from the 50% income exemption under the impatriate regime to the €200,000 flat tax for high-net-worth individuals — can make Italy one of the most tax-efficient destinations in Europe.

The key takeaways for your expat tax Spain Italy move are:

Time your move strategically to cleanly break Spanish residency and establish Italian residency within the same calendar year.
Address all Spanish exit obligations including the final tax return, Modelo 030 notification, and potential exit tax on large shareholdings.
Evaluate Italy's special regimes immediately — the impatriate regime alone can cut your Italian income tax by half for five years.
Leverage the Spain-Italy double taxation treaty to avoid paying tax twice on the same income.
Work with qualified cross-border tax professionals who understand both jurisdictions.
