✦The essentials

What actually decides your taxes

The numbers below are indicative - your commercialista confirms the exact figures for your activity.

Codice ATECO
Your activity code sets the profitability coefficient - effectively how much you are taxed - and whether you must register with the Camera di Commercio. Choose it carefully; it shapes everything.
5% vs 15%
On Forfettario, new activities pay 5% for the first 5 years - but only if the commercialista ticks "nuova attivita". Miss that box and you are locked into 15%, with no way to fix it.
INPS ~26%
Freelancers must enrol in INPS Gestione Separata. The hidden ~26% pension contribution on your income is on top of your tax rate - budget for it from day one.
Dec 31 deadline
Open your Partita IVA before the end of your arrival year, or you cannot declare Italian income for that whole tax year. You cannot open a P.IVA backdated.
1 - 3 days
Opening through a commercialista takes 1 to 3 days. Cost ranges from 0 to 200 EUR - many do it free when you sign an annual service contract.
✦Avoid these

Common Partita IVA mistakes

Opening Forfettario without residenza

The Agenzia delle Entrate can audit you 2 to 7 years later and reclassify your tax position - the snap card flags this as an audit risk.

Wait for your permesso, register your residenza, then open the Partita IVA in the correct order.

Missing the 5% new-activity checkbox

On the AA9/12 form, only a checked "nuova attivita" box locks in the 5% rate for your first 5 years. If your commercialista leaves it blank, you are locked into 15% with no way to fix it.

Ask to see the LM section of the filed AA9/12 form and confirm the 5% rate appears before you leave the appointment.

Forgetting to budget for INPS (~26%)

The Forfettario headline rate (5 to 15%) is only part of your real cost. INPS Gestione Separata adds roughly 26% on top - many freelancers are caught short in their first year.

Calculate your expected tax AND INPS contribution together from day one, before issuing your first invoice.

Waiting until after Dec 31 to open

You cannot open a Partita IVA backdated. If you miss the end of your arrival year, you lose the ability to declare Italian income for that entire tax year.

Open your Partita IVA before December 31 of the year you arrive or start freelancing, even if your income that year is small.

Choosing the wrong codice ATECO

The ATECO code sets your profitability coefficient and determines whether Camera di Commercio registration is required - a mismatch affects how much you are taxed and your compliance obligations.

Confirm the correct ATECO code with your commercialista before filing; changing it later requires an amendment and may affect your tax history.

✦Real cases from our community

People who did it

Condensed from the discussion on our forum, where members answer questions and post updates.

The right path is to wait for your permesso, register residenza, then open on Forfettario. I almost rushed it - opening without residenza can get audited years later.

Double-check the AA9/12 form yourself. My commercialista almost left me on 15% instead of the 5% new-activity rate - that mistake cannot be undone.

Nobody warned me about the INPS 26%. The Forfettario rate looks great until you add the pension contribution - plan for both, not just the tax.

✦The process

From Codice Fiscale to your first invoice

  1. 1

    Get your Codice Fiscale first

    You can obtain it before your permesso with a D visa plus ricevuta. It is the prerequisite for everything that follows - the bank account, the lease and the Partita IVA itself.

  2. 2

    Find a commercialista

    They file the Comunicazione Unica - the single form that registers you with the Agenzia delle Entrate, INPS and the Camera di Commercio all at once.

  3. 3

    Choose your codice ATECO

    Pick the activity code that matches your real work. It sets your profitability coefficient and whether Camera di Commercio registration is required.

  4. 4

    Pick your tax regime

    Forfettario (5 to 15%) suits most freelancers; Ordinario means IRPEF 23 to 43%. Insist the 5% new-activity box is ticked, and enrol in INPS Gestione Separata.

  5. 5

    Verify everything in person

    Request the AA9/12 opening form, confirm the 5% rate appears in the LM section, and keep a copy of what was filed. Then issue your first fattura elettronica.

The mistake you cannot undo: opening on Forfettario without residenza, or letting the 5% new-activity box go unticked. The Agenzia delle Entrate can audit you 2 to 7 years later - do it in the right order and check the paperwork yourself.
✦FAQ

Partita IVA questions, answered

Do I need a Codice Fiscale before I can open a Partita IVA?

Yes. The Codice Fiscale is the prerequisite for everything - the bank account, the lease and the Partita IVA itself. You can obtain it before your permesso arrives if you have a D visa plus the ricevuta (receipt of your permit application).

What is the Forfettario regime and who qualifies?

Forfettario is a flat-tax regime that lets most freelancers pay 5% for the first 5 years of a new activity, then 15% after that - compared with IRPEF rates of 23 to 43% under Ordinario. You must have residenza in Italy to use it, and you must not exceed the annual revenue ceiling.

What does a commercialista actually do, and do I need one?

A commercialista files the Comunicazione Unica - the single form that registers you with the Agenzia delle Entrate, INPS and the Camera di Commercio all at once. While it is technically possible to file yourself, the 5% vs 15% checkbox and the ATECO code choice are high-stakes decisions where a mistake cannot be undone. Many commercialisti do the opening for free when you sign an annual service contract.

What is INPS Gestione Separata and how much does it cost?

INPS Gestione Separata is the pension contribution scheme for freelancers without a dedicated professional fund. The rate is roughly 26% of your taxable income. It is mandatory and is on top of your income tax - not included in the Forfettario headline rate.

How long does it take to open a Partita IVA?

Through a commercialista the process typically takes 1 to 3 days. Cost ranges from 0 to around 200 EUR depending on the accountant and whether you sign an ongoing service contract.

What is the Comunicazione Unica?

It is the unified declaration that a commercialista files on your behalf. A single form simultaneously registers you with the Agenzia delle Entrate (tax authority), INPS (social security) and, where required for your ATECO code, the Camera di Commercio (business register).

Can I open a Partita IVA on a tourist visa or while waiting for my permesso?

Generally no. Forfettario requires Italian residenza, which requires a valid permesso di soggiorno. Opening without residenza creates a serious audit risk - the Agenzia delle Entrate can review your situation for up to 7 years after the fact. The correct order is: permesso first, residenza registration second, Partita IVA third.

What is fattura elettronica and when do I issue it?

Fattura elettronica is the mandatory electronic invoice system in Italy. Once your Partita IVA is open, you must issue all invoices through the SDI (Sistema di Interscambio) government platform. Your commercialista or a billing tool handles the technical submission; you need to do this for every invoice from your first client onward.
