Whether you're an Italian resident, an expat working in Milan, or a non-resident earning income from Italian sources, understanding how to file your income tax return in Italy is essential. Italy's tax system — centered around the Imposta sul Reddito delle Persone Fisiche (IRPEF) — can feel complex, but with the right guidance it becomes entirely manageable.

This Italy tax filing guide walks you through every step for the 2025/2026 tax year, from determining your tax obligations to submitting your declaration and paying what you owe. By the end, you'll know exactly how to file taxes in Italy with confidence.

Who Needs to File an Income Tax Return in Italy?

Not everyone in Italy is required to file a tax return. Understanding whether you have a filing obligation is the critical first step.

Italian Tax Residents

You are considered a tax resident in Italy if, for more than 183 days in a calendar year, you meet any of the following criteria:

  • You are registered in the Anagrafe della Popolazione Residente (Registry of the Resident Population)
  • You have your domicile (center of vital interests) in Italy
  • You have your habitual abode in Italy

Italian tax residents are subject to tax on their worldwide income, regardless of where it is earned.

You must file a return if you:

  • Earned income from more than one employer during the tax year
  • Have self-employment or freelance income
  • Earned rental income, capital gains, or foreign-source income
  • Want to claim deductions or tax credits not applied by your employer
  • Earned income that was not subject to withholding tax

You generally do NOT need to file if:

  • You have only one employer and your taxes were fully withheld through your payslip
  • Your total income falls below the tax-free threshold (approximately EUR 8,500 for employees in 2025)
  • You only received income already subject to imposta sostitutiva (substitute tax) or final withholding taxes

Non-Residents

Non-residents must file an Italian tax return if they earned Italian-source income — such as rental income from Italian property, employment income for work performed in Italy, or certain investment income — that was not fully taxed at source.

Understanding Italy's Income Tax Rates (IRPEF) for 2025/2026

Italy uses a progressive income tax system with multiple brackets. For the 2025 tax year, the IRPEF rates are as follows:

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

These rates apply to your total taxable income after allowable deductions and personal allowances.

Practical Example

If you earn EUR 50,000 in gross taxable income in 2025, your IRPEF calculation would be:

  1. First EUR 28,000 × 23% = EUR 6,440
  2. Remaining EUR 22,000 (from EUR 28,001 to EUR 50,000) × 35% = EUR 7,700
  3. Total IRPEF = EUR 14,140

This is before applying any tax credits or deductions, which can significantly reduce your final liability. Want to see your exact numbers? Use our Italy Income Tax Calculator to estimate your personal tax liability in minutes.

Regional and Municipal Surcharges

On top of the national IRPEF, you will also owe:

  • Regional surcharge (addizionale regionale): Ranges from approximately 1.23% to 3.33%, depending on your region of residence
  • Municipal surcharge (addizionale comunale): Ranges from 0% to 0.9%, depending on your municipality

These surcharges are calculated on the same taxable income base as the national IRPEF.

Step-by-Step: How to File Your Income Tax Return in Italy

Here is the complete process to file your income tax return in Italy for the 2025/2026 tax year.

Step 1: Obtain Your Tax Identification Code (Codice Fiscale)

Before you can do anything tax-related in Italy, you need a Codice Fiscale. This is Italy's equivalent of a tax identification number. Italian citizens receive one at birth; foreigners can obtain one from the Agenzia delle Entrate (Italian Revenue Agency) or through an Italian consulate abroad.

Step 2: Gather Your Income Documentation

Collect all documents related to your income and deductible expenses for the tax year (January 1 – December 31, 2025). Key documents include:

  • CU (Certificazione Unica): Issued by your employer or pension provider by mid-March, this document summarizes your employment income and taxes withheld
  • Invoices and receipts for self-employment or freelance income
  • Bank statements showing interest income and dividends
  • Rental contracts and income records for Italian property
  • Foreign income documentation (pay stubs, bank statements, foreign tax returns)
  • Receipts for deductible expenses: medical expenses, mortgage interest, education costs, renovation expenses, charitable donations, and more

Step 3: Choose the Right Tax Form

Italy has several tax return forms. Choosing the correct one is crucial:

  • Modello 730: The simplified form for employees and pensioners. It is processed by your employer or a CAF (Centro di Assistenza Fiscale — tax assistance center), and any refund or additional tax is applied directly through your payslip. Available for submission from mid-April.
  • Modello Redditi PF (Persone Fisiche): The comprehensive form for self-employed individuals, freelancers, those with foreign income, non-residents, and anyone who cannot use the Modello 730. This form requires direct payment of taxes owed.
  • Modello 730 Precompilato: Since 2015, the Agenzia delle Entrate prepares a pre-filled tax return for most taxpayers, available through their online portal. This includes data from employers, banks, insurance companies, and healthcare providers.

Tip: The pre-filled Modello 730 is the easiest option for most employees. You simply review, modify if necessary, and submit.

Step 4: Access the Agenzia delle Entrate Online Portal

To file electronically — which is the standard method — you need access to the Agenzia delle Entrate website. You can authenticate using:

  • SPID (Sistema Pubblico di Identità Digitale) — Italy's public digital identity system
  • CIE (Carta d'Identità Elettronica) — electronic ID card
  • CNS (Carta Nazionale dei Servizi) — national services card

For foreigners, obtaining SPID credentials is the most practical option. Several certified providers offer SPID registration, some of which support remote identity verification for non-Italian ID holders.

Step 5: Review and Complete Your Tax Return

Once logged in:

  1. Access the pre-filled return (dichiarazione precompilata)
  2. Review all pre-populated data — income figures, withholding taxes, deductible expenses
  3. Add any missing income — especially foreign income, rental income, or freelance earnings not reported by third parties
  4. Claim additional deductions and credits not automatically included (see the section below)
  5. Verify regional and municipal surcharges are correct for your place of residence

Step 6: Submit Your Tax Return

Once reviewed and completed:

  • Modello 730: Submit electronically through the Agenzia delle Entrate portal, through your employer, or through a CAF/tax professional. The deadline is typically September 30 of the year following the tax year.
  • Modello Redditi PF: Submit electronically by November 30 of the year following the tax year. Paper filing (only in limited cases) has an earlier deadline, usually by June 30.

Step 7: Pay Any Tax Owed

If you used the Modello 730, any additional tax owed or refund due is processed directly through your payslip or pension — no separate payment needed.

If you used the Modello Redditi PF, you must pay any balance due using the Modello F24 payment form. Payments can be made:

  • Online through your bank
  • At authorized post offices or banks
  • Through the Agenzia delle Entrate's online services

Key payment deadlines for the 2025 tax year (filing in 2026):

  • Balance + first advance payment: June 30, 2026 (or July 30 with a 0.40% surcharge)
  • Second advance payment: November 30, 2026

Key Deductions and Tax Credits to Reduce Your Italian Tax Bill

Italy offers a generous range of deductions (deduzioni) and tax credits (detrazioni) that can substantially lower your tax liability.

Common Tax Credits (Detrazioni — typically 19% of eligible expenses)

  • Medical and healthcare expenses (above a EUR 129.11 threshold)
  • Mortgage interest on a primary residence (up to EUR 4,000 per year)
  • Education and university fees
  • Childcare expenses and dependent family member credits
  • Charitable donations to qualifying organizations
  • Veterinary expenses
  • Funeral expenses (up to EUR 1,550)

Tax-Deductible Items (Deduzioni — reduce taxable income directly)

  • Social security contributions (INPS contributions)
  • Supplementary pension fund contributions (up to EUR 5,164.57 per year)
  • Alimony payments to a former spouse (by court order)
  • Medical assistance contributions for domestic workers

Renovation and Energy Efficiency Bonuses

Italy has historically offered significant tax credits for property-related investments, though these change frequently:

  • Building renovation bonus: 50% tax credit on eligible renovation expenses (spread over 10 years), though rates and caps may be adjusted for 2025
  • Energy efficiency bonus (Ecobonus): Up to 65% credit for energy-saving improvements
  • Furniture and appliance bonus: 50% credit on furnishings for renovated properties

Always verify the current availability and terms of these incentives on the Agenzia delle Entrate website, as legislative updates are frequent.

Tax Filing for Expats and Non-Residents in Italy

Expats Moving to Italy

Italy offers attractive tax incentive regimes for skilled workers and professionals relocating to Italy:

  • Impatriate Workers Regime (Regime Impatriati): Qualifying individuals who transfer their tax residence to Italy can benefit from a significant tax exemption on employment and self-employment income. Under recent reforms, 50% of qualifying income may be exempt from taxation (previously 70% in earlier years), subject to specific conditions including not having been resident in Italy for the previous two tax years and committing to at least two years of residence.

  • Flat Tax for New Residents (Regime Forfettario per Neo-Residenti): High-net-worth individuals transferring their residence to Italy can opt for a EUR 200,000 annual flat tax on all foreign-source income (with an additional EUR 25,000 per family member). Italian-source income remains subject to ordinary IRPEF rates.

These regimes require careful planning and proper election in your tax return. Professional advice is strongly recommended.

Non-Residents Filing in Italy

If you are a non-resident with Italian-source income:

  • You must use the Modello Redditi PF (not the Modello 730)
  • You are taxed only on Italian-source income
  • You cannot claim most personal deductions and credits available to residents
  • Italy has double taxation agreements (DTAs) with over 90 countries. If your home country has a treaty with Italy, you may be entitled to reduced withholding rates or foreign tax credits to prevent being taxed twice on the same income

Common Mistakes to Avoid When Filing Taxes in Italy

Filing errors can lead to penalties, interest charges, and even audits. Here are the most frequent mistakes:

  1. Failing to report foreign income: Italian tax residents must declare worldwide income. Failure to report foreign bank accounts (through the Quadro RW of Modello Redditi), foreign investments, or foreign employment income is a serious compliance violation.

  2. Missing the IVAFE and IVIE obligations: Italian residents with foreign financial assets must pay IVAFE (a 0.2% annual tax on foreign financial investments) and IVIE (a tax on foreign real estate, generally 1.06% of cadastral or purchase value).

  3. Using the wrong tax form: Filing a Modello 730 when you have foreign income or complex situations that require a Modello Redditi PF can cause processing issues.

  4. Not claiming all eligible deductions: Many taxpayers leave money on the table by forgetting to claim medical expenses, renovation credits, or supplementary pension deductions.

  5. Missing payment deadlines: Late payments incur interest and penalties (typically 30% of the unpaid amount, reducible through voluntary regularization — ravvedimento operoso).

  6. Ignoring the pre-filled return: The Agenzia delle Entrate's pre-compiled declaration often contains errors or omissions. Always review it carefully before accepting.

  7. Not keeping records: Italian tax law requires you to retain supporting documentation for at least five years from the filing date (and longer in some cases). Keep all receipts, CU forms, and contracts organized.

Frequently Asked Questions About Filing Taxes in Italy

When is the deadline to file income tax in Italy?

For the 2025 tax year, the Modello 730 must be filed by September 30, 2026, and the Modello Redditi PF must be filed electronically by November 30, 2026.

Can I file my Italian tax return online?

Yes. Electronic filing through the Agenzia delle Entrate portal is the standard and preferred method. You need SPID, CIE, or CNS credentials to access the system.

Do I need a tax professional (commercialista) to file?

It's not legally required for simple cases. Employees with straightforward income can use the pre-filled Modello 730 independently or through a free CAF. However, a commercialista (chartered accountant) is highly recommended for self-employed individuals, those with foreign income, and anyone with complex financial situations.

What happens if I file late or don't file at all?

Late filing penalties range from EUR 250 to EUR 1,000 for returns with no tax due, and from 120% to 240% of the unpaid tax for returns with a balance due. Using ravvedimento operoso (voluntary correction) allows you to reduce penalties significantly if you act before the tax authority contacts you.

How do I report foreign bank accounts in Italy?

Foreign financial assets must be reported in Quadro RW of the Modello Redditi PF. This includes bank accounts, investment portfolios, cryptocurrency holdings, and real estate abroad. Even if no tax is due, the reporting obligation is mandatory.
