Missing a tax deadline in Italy can result in hefty penalties, interest charges, and unnecessary stress. Whether you're an Italian resident, an expat living in Rome or Milan, or a non-resident earning income from Italian sources, understanding the Italy tax deadlines 2025/2026 is essential to staying compliant with the Agenzia delle Entrate (Italian Revenue Agency).

This complete Italy tax calendar for 2025/2026 covers every critical date you need to know — from annual income tax filing to monthly and quarterly payment obligations. We'll walk you through when to file taxes in Italy, how to avoid common pitfalls, and what happens if you miss a deadline.

Before diving into the dates, you can estimate your Italian income tax liability using our Italy Income Tax Calculator to plan your payments throughout the year.

Understanding the Italian Tax Year

Italy's tax year follows the calendar year, running from January 1 to December 31. For the 2025/2026 tax season, you'll be dealing with two overlapping cycles:

  • Tax Year 2024: Income earned from January 1 to December 31, 2024, which is declared and settled during 2025.
  • Tax Year 2025: Income earned from January 1 to December 31, 2025, for which advance payments (acconti) are due during 2025 and the final balance is settled in 2026.

This overlap is one of the most confusing aspects of the Italian tax system. In any given year, you're simultaneously settling the previous year's balance and making advance payments toward the current year's liability.

Who Must File a Tax Return in Italy?

Before reviewing the Italy tax calendar, it's important to understand who is required to file:

  • Tax residents: Individuals who are registered in the Italian civil registry (Anagrafe), have their domicile in Italy, or reside in Italy for more than 183 days per year are considered tax residents. They must declare their worldwide income.
  • Non-residents: Individuals who earn income from Italian sources (e.g., rental income, employment income, capital gains from Italian assets) must file an Italian tax return reporting only their Italian-source income.
  • Exemptions: Certain taxpayers who only receive income from a single employer (and whose tax is fully withheld at source) or whose total income falls below specific thresholds may be exempt from filing. However, it's always wise to confirm with a tax professional.

Key Italy Tax Deadlines for 2025

The following are the most critical dates in the Italy tax calendar for 2025, applicable to income earned in the 2024 tax year and advance payments for 2025.

Modello 730 — Simplified Tax Return

The Modello 730 is the simplified tax return used by employees and retirees. It's the most common form for individuals whose tax is primarily withheld at source.

  • April 30, 2025: The Agenzia delle Entrate makes the pre-filled Modello 730 (dichiarazione precompilata) available online through its portal.
  • September 30, 2025: Final deadline to submit the Modello 730 (whether directly online, through a CAF — Centro di Assistenza Fiscale, or through an authorized tax professional).

Important note: If you submit through a CAF or tax professional, they may have earlier internal deadlines, so plan accordingly.

Modello Redditi PF — Full Tax Return

The Modello Redditi Persone Fisiche (PF) is the comprehensive tax return required for self-employed individuals, freelancers, those with foreign income, and anyone who cannot use the Modello 730.

  • April 30, 2025: Pre-filled version available online.
  • June 30, 2025: Deadline for the balance payment (saldo) for tax year 2024 and the first advance payment (primo acconto) for tax year 2025 — without interest.
  • July 30, 2025: Extended payment deadline for the balance and first advance, subject to a 0.40% surcharge on the amount due.
  • October 31, 2025: Final deadline to electronically submit the Modello Redditi PF for tax year 2024.
  • November 30, 2025: Deadline for the second advance payment (secondo acconto) for tax year 2025.

Key Italy Tax Deadlines for 2026

For income earned during the 2025 tax year, the settlement and filing process extends into 2026. While official dates for 2026 are typically confirmed later in the year, based on established patterns, here are the expected Italy tax deadlines for 2026:

  • April 30, 2026: Pre-filled tax returns (Modello 730 and Redditi PF) expected to be available online.

These dates are projections based on current legislation. The Italian government may adjust deadlines through official decrees, as has happened in recent years. Always verify with the Agenzia delle Entrate's official website.

Understanding Italy's Advance Payment System (Acconti)

One of the most distinctive features of the Italian tax system — and a common source of confusion for expats and first-time filers — is the advance payment system (sistema degli acconti).

How Advance Payments Work

When you file your annual return, you don't just settle the previous year's balance. You're also required to make advance payments toward the current year's tax liability. These advance payments are calculated based on your previous year's tax bill:

  1. First advance (primo acconto): Due by June 30, equal to 40% of the total advance amount.
  2. Second advance (secondo acconto): Due by November 30, equal to 60% of the total advance amount.

The total advance is generally 100% of the previous year's net tax liability (after withholdings and credits), provided that liability exceeds EUR 51.65.

Practical Example

Let's say you're a freelancer who owed EUR 10,000 in net IRPEF (income tax) for 2024 after all withholdings:

  • Total advance for 2025: EUR 10,000
  • First advance (June 30, 2025): EUR 4,000 (40%)
  • Second advance (November 30, 2025): EUR 6,000 (60%)

If your actual 2025 income turns out to be lower, you can reduce your advance payments using the metodo previsionale (forecast method). However, if you underestimate by too much, you'll face penalties. Conversely, any overpayment will be credited against future taxes or refunded.

Italy Income Tax Rates for 2025

To give context to the deadlines, here are the current IRPEF (Imposta sul Reddito delle Persone Fisiche) brackets for the 2025 tax year, following the reform that reduced the number of brackets from four to three:

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

Example Calculation

If you earn EUR 50,000 in taxable income in 2025:

  • First EUR 28,000 × 23% = EUR 6,440
  • Next EUR 22,000 (EUR 28,001 – EUR 50,000) × 35% = EUR 7,700
  • Total IRPEF: EUR 14,140

In addition to national IRPEF, you'll also owe regional surcharges (addizionale regionale) ranging from approximately 1.23% to 3.33% and municipal surcharges (addizionale comunale) of up to 0.9%, depending on your municipality.

Special Considerations for Expats and Non-Residents

Italy has several provisions that affect the tax deadlines and obligations for expatriates and non-residents.

The Flat Tax Regime for New Residents (Regime dei Neo-Residenti)

High-net-worth individuals who transfer their tax residence to Italy may qualify for the flat tax regime under Article 24-bis of the TUIR. Under this regime, qualifying individuals pay a flat tax of EUR 200,000 per year on all foreign-source income, regardless of the amount. Italian-source income is taxed under normal IRPEF rates.

  • The flat tax is due by June 30 of each year.
  • This regime can be extended to family members for an additional EUR 25,000 per person per year.
  • The option is valid for a maximum of 15 years.

The Impatriati Regime (Incentive for Workers Moving to Italy)

Workers who transfer their tax residence to Italy may benefit from significant income tax exemptions. Under the revised regime effective from 2024:

  • 50% of employment or self-employment income is exempt from taxation (up to EUR 600,000 of qualifying income), effectively halving the tax rate.
  • The worker must maintain Italian tax residence for at least 4 years.
  • Enhanced benefits are available for those with minor children or who purchase residential property in Italy.

The same filing deadlines apply, but calculating the correct exempt amount is crucial. Errors can result in the loss of the benefit.

Double Taxation Agreements

Italy has an extensive network of double taxation treaties (DTTs) with over 90 countries, including the United States, United Kingdom, Germany, France, Canada, and Australia. These treaties generally:

  • Determine which country has the primary right to tax specific income types
  • Provide mechanisms to claim foreign tax credits
  • Reduce or eliminate withholding taxes on dividends, interest, and royalties

Foreign tax credits must be claimed in the year the foreign tax becomes "definitive" (final and non-refundable), and the relevant documentation must be maintained. The filing deadlines remain the same, but accurate reporting of foreign income and credits requires careful planning.

Non-Resident Filing Obligations

Non-residents earning Italian-source income must file the Modello Redditi PF (not the Modello 730) and follow the same deadlines. Common Italian-source income for non-residents includes:

  • Rental income from Italian properties
  • Employment income for work performed in Italy
  • Capital gains from the sale of Italian real estate
  • Pension income from Italian sources

Penalties for Missing Italy Tax Deadlines

The Italian tax system imposes significant penalties for late filing and late payment. Understanding these consequences underscores the importance of adhering to the Italy tax deadlines 2025/2026.

Late Filing Penalties

  • Filed within 90 days of the deadline: A reduced penalty of EUR 25 (if no tax is due) to 1/10 of the standard penalty through the ravvedimento operoso (voluntary correction) mechanism.
  • Filed more than 90 days late: Penalties range from 120% to 240% of the tax due, with a minimum of EUR 250.
  • Failure to file entirely: The penalty is 120% to 240% of the unpaid tax. If no tax is owed, a fixed penalty between EUR 250 and EUR 1,000 applies.

Late Payment Penalties

  • Ravvedimento operoso (voluntary late payment with self-correction) allows significantly reduced penalties:
    • Within 14 days: 0.1% per day of the unpaid amount
    • Within 30 days: 1.5% of the unpaid amount
    • Within 90 days: 1.67% of the unpaid amount
    • Within the filing deadline of the following year: 3.75% of the unpaid amount
  • Interest: Legal interest accrues at 2.5% per annum (2025 rate, subject to annual adjustment).

Common Mistakes to Avoid

  1. Forgetting the advance payments: Many newcomers to the Italian system are surprised by the obligation to make advance payments. Missing the June 30 or November 30 deadlines triggers automatic penalties.
  2. Not reporting foreign income: Italian tax residents must declare worldwide income. Failing to report foreign bank accounts, investments, or income can result in severe penalties and potential criminal liability.
  3. Missing the RW form (Quadro RW): Residents must declare all foreign financial assets and investments held outside Italy, even if they generate no income. This is reported in Quadro RW of the Modello Redditi PF.
  4. Confusing Modello 730 and Redditi PF deadlines: These two forms have different filing deadlines (September 30 vs. October 31). Using the wrong form or missing the correct deadline is a frequent error.
  5. Ignoring municipal and regional surcharges: Many taxpayers focus only on national IRPEF and are caught off guard by the additional regional and municipal surcharges.
