How to file an Italian tax return (Modello 730 or Redditi)

Articles explain general principles and are for information only. They do not constitute legal, tax or other professional advice. Real outcomes depend on residence, income structure, documents and timing.

Start case analysis

Filing a tax return in Italy is usually straightforward: choose the form, log in, submit the data. For most people, it's a routine task once a year. But if you have income from another country, recently moved, work remotely, or run a business outside Italy, the return is not just about numbers. This is the moment when the tax system records your status: who it considers a resident, which income it treats as Italian, and which country it sees as your main place of taxation.

  • In typical cases, you can file the return using the standard process.
  • In international situations, it's important not only to submit the form, but also to check your status.
  • You can fill everything in correctly and still be recorded incorrectly in the system.
  • Problems usually appear later, not at the moment of filing.
  • It's better to check the logic now than fix the consequences later.

Steps

  1. Decide which form you need

    In Italy, two forms are used most often:
    • Modello 730 — for employees and pensioners
    • Modello Redditi — for freelancers, business owners, and people with more complex income
    If you only have a salary in Italy, Modello 730 is usually enough. If you have a business, freelance income, or foreign income, Modello Redditi is more likely the right choice.
  2. Choose how to file

    You can submit your return in three ways:
    • through your personal account on the Agenzia delle Entrate website
    • via a CAF (tax assistance center)
    • through an accountant (commercialista)
    Technically, all three options are equivalent. The difference is who helps you with the filing.
  3. Prepare your information

    Before logging in, collect:
    • your income details for the year
    • information on taxes already paid in Italy and abroad
    • family and deduction details
    • bank details for refunds or payments
    If you have foreign income, keep documents from the other country ready.
  4. File the return

    Log in, review the pre-filled version (if available), add any missing data, and submit the form. After submission, save:
    • the filing receipt
    • a copy of the return
    • the confirmation of acceptance
    These documents protect you if questions come up later.

A control point for non-typical situations

If at least one of these applies to you:
  • you live between countries
  • you work remotely for a foreign company
  • you earn income outside Italy
  • you recently changed your country of residence
after filing, it's important to check not only the numbers, but how the system classified you: as an Italian tax resident or a non-resident, which income the system treats as Italian, which country it considers your main place of taxation. This is where most future problems start — not because of the form, but because of the status.

Tips

  • In typical cases, filing a return is just a routine task.
  • In international cases, it is also a point where your status is fixed.
  • CAF and online systems help you fill in the form, but they don't always review your cross-border logic.
  • If you have doubts, it's better to clarify your situation before an audit, not after.
  • Keep all documents related to income and residency for several years.

FAQ

Yes, but it's important not only to file, but also to understand how the tax system classifies you after submission.

A CAF helps you fill in the form. It doesn't always assess how your situation looks in an international context.

Most often not in the filing year, but later — during an audit, after a move, or through data exchange between countries.

When you live and earn only in Italy and have no foreign income or cross-border ties.

When you have a second country — in your income, your work, or your plans.
