Reporting and Paying Italian Tax on Worldwide Investment Income: A Foreign National’s Guide

If you’re a foreign national who has become a tax resident (residente fiscale) in Italy, understanding how to report and pay Italian taxes on worldwide investment income is paramount. Whether you’ve built up investments abroad or are earning returns from Italian sources, the Italian tax regime holds residents liable for income earned globally—including dividends, interest, and capital gains.

What Counts as Investment Income for Italian Tax Residents?

Italy’s tax rules are comprehensive. If you reside in Italy for tax purposes, you’re required to declare—and will be taxed on—the following types of investment income from both Italian and foreign sources:

• Dividends: Any profits or distributions from shares, mutual funds, or similar assets, whether paid by Italian or foreign companies.
• Interest: This includes income from bank deposits, bond coupons, and any similar yield, regardless of whether the bank or bond issuer is Italian or foreign.
• Capital Gains: Profits realized from selling shares, stocks, investment funds (including ETFs), bonds, or other financial assets.

All of these must be declared annually by tax residents in Italy, even if earned outside the country.

Applicable Tax Rates on Investment Income

The Personal Income Tax Framework

Italian individuals are taxed on a progressive income scale known as IRPEF (Imposta sul Reddito delle Persone Fisiche) plus regional and municipal surtaxes. For the 2025 fiscal year, IRPEF national brackets are:

• 23% on taxable income up to €28,000
• 35% on income from €28,001 to €50,000
• 43% on income exceeding €50,000

Local surcharges may further increase your overall liabilities depending on the region and municipality.

Investment Income: Withholding vs. Annual Taxation

Many Italian financial products apply a withholding tax (imposta sostitutiva) at source, so you may not have to include these separately in your annual return if tax has already been paid. However, if you earn dividends, interest, or capital gains from foreign sources, or hold assets abroad, these generally must be reported in your annual tax return using the Modello Redditi Persone Fisiche (Modello Redditi PF). The income will then be taxed at your personal rates, net of any creditable foreign taxes.

Crypto-assets: Special Note

With ongoing legislative tweaks, capital gains from crypto-assets for nonresidents are subject to an 18% substitute tax in 2025, increasing to 33% in 2026. While this specific rate targets nonresidents, it signals rapid policy shifts that can impact how these assets are taxed. Residents should be vigilant about evolving guidance for crypto taxation in their filings.

How to Report Your Investment Income in the Italian Tax Return

Which Return to File: Modello 730 or Modello Redditi PF?

If you’re an employee or pensioner with solely Italian income and no complex financial holdings abroad, you may use the simplified 730 form (Modello 730). But once you have:

• Foreign investment income, or
• Foreign bank accounts, portfolios, or real estate, or
• Other complex financial arrangements abroad

—you will need to file using the Modello Redditi PF.

Key Documents You’ll Need

• Bank and brokerage annual statements for all accounts (Italian and foreign)
• Dividend and interest vouchers showing each payment and any taxes withheld
• Transaction histories showing acquisition and disposal dates, costs, and sale proceeds for all relevant financial assets
• Evidence of foreign taxes paid (for double tax relief purposes)

Filing and Payment Process

Italian resident individuals must generally submit their Modello Redditi PF electronically using the Agenzia delle Entrate’s web portal. Alternatively, tax filing centers (CAF) or qualified professionals can transmit your return (note: on ItalianTaxes.com, the entire process is managed online without bureaucracy).

• Deadline for FY 2024: By October 31, 2025
• Tax Payment Due: First balance and estimates generally by June 30, 2025; second payment/advance by December 1, 2025
• Late filing: Allowed within 90 days with a minor penalty

Payments are made using the F24 form (modello F24), which can be completed and paid easily online.

Worldwide Income Rule: Comprehensive Reporting

Italian tax residency means full liability on global income. This "worldwide income rule" means you must declare and pay tax on all qualifying investment income—Italian and non-Italian—every year in your return. Omission or under-reporting may result in significant penalties.

Practical Tips to Stay Compliant and Avoid Double Taxation

1. Use the correct form: Foreign financial income calls for Modello Redditi PF. Don’t use the pre-filled 730 (precompilato) if you need to add investments not known to the Italian authorities.
2. Keep detailed documentation: Collect all foreign statements, tax certificates, and acquisition/sale records for each investment—especially if you plan to claim credits for foreign taxes paid.
3. Leverage tax treaty relief: Check if Italy has a double taxation treaty with the country where your investment income originated. Foreign taxes withheld may be credited against Italian liabilities, though precise calculations are required to avoid mismatches.
4. Plan for deadlines: Mark your calendars for the June/December payment deadlines and the October filing due date. Early planning mitigates cash flow surprises.
5. Consider your total IRPEF exposure: Investment income will be added to your other income and might push you into higher tax brackets, so monitor all sources for efficient year-end planning.
6. Professional review recommended for complex filings: If you’re adjusting or supplementing a pre-filled return or encounter complex cross-border income, having a trusted technology-driven service (such as ItalianTaxes.com) can help ensure completeness and compliance.

Other Points for Foreign Nationals in Italy

• Understand your filing type: Employees or pensioners with simple tax affairs may use 730, but international asset-holders should file Modello Redditi PF.
• Start early each spring: Since Italy uses a calendar-year basis (January–December), it’s smart to organize your investment documentation as soon as year-end statements are available.
