Step-by-Step Guide to Getting a Partita IVA in Italy

Opening a Partita IVA is the legal gateway to operate as a sole trader (impresa individuale) or independent professional (libero professionista) in Italy. The process is straightforward once you know which forms to file, which bodies to notify, and how your tax and social-security choices affect cash flow. Follow the steps below and you’ll set up correctly the first time—without nasty surprises at invoice time.

1) Confirm you need a Partita IVA (and your right to open one)

You need a Partita IVA when your activity is habitual and organized (not occasional). Freelance services, consulting, digital products, crafts, retail, and most paid services qualify once there is continuity or an organized setup (website, pricing, recurring clients).

• EU/EEA/Swiss citizens can open directly.

• Non-EU nationals must hold a residence permit that allows self-employment before applying.

If you only carry out occasional work, Italy provides non-business receipts; that option ends the moment activity becomes systematic.

2) Choose the correct ATECO code (your activity label)

The ATECO code classifies what you do. It drives:

• your profitability coefficient if you opt for the flat-rate regime (forfettario),

• whether you must register as impresa with the Chamber of Commerce,

• possible sectoral licenses (food, beauty, transport, etc.).

Scan the official list and pick the closest real-world match. If you’ll operate across multiple services, select a primary code and add secondary codes if needed.

3) Decide your tax regime before you file

You’ll choose the regime on day one, and it shapes invoices, bookkeeping, and advances:

Flat-rate regime (forfettario).

• Revenue ceiling generally €85,000 per year; if you exceed €100,000 during the year, ordinary VAT rules apply from the operation that breaches.

• Pays a substitute tax (imposta sostitutiva)—15%, or 5% for the first five years if you meet the “new activity” conditions.

• No VAT charged, no input VAT recovered, simplified records, and no withholding tax applied by your clients when you insert the standard clause on invoices.

Ordinary regime (semplificato/ordinario).

• You charge VAT and recover input VAT.

• Income is taxed under IRPEF progressive bands with deductions/credits and local add-ons.

• More bookkeeping, but often better if you have significant costs or sell with high VAT on inputs.

4) File the AA9/12 and get the Partita IVA number

Individuals (professionals and sole traders) open, modify, or close their position with Form AA9/12 at the Agenzia delle Entrate. File online with SPID/CIE/CNS, through a tax professional, or at a local office. The form asks for:

• Personal data and codice fiscale;

• ATECO code(s);

• Start date of the activity;

• Chosen tax regime;

• PEC (digital domicile) if available—strongly recommended.

Submission generates your Partita IVA. Keep the protocol receipt—you’ll need it for further registrations.

5) If you’re a trader or artisan, register the business too

Professionals often stop after AA9/12. Traders and artisans must additionally complete Comunicazione Unica to enroll in the Registro Imprese (Chamber of Commerce) and, where applicable, notify the municipal SUAP with a SCIA (certified start of activity). Some activities also require INAIL insurance.

• Budget for Chamber fees and any license costs.

• Keep a PEC address active; many authorities and clients now require it.

6) Enroll in the correct social-security fund

Everyone pays into one social-security channel, depending on what you do:

• Professionals without an Order/Cassa → INPS Gestione Separata (contribution rate and yearly minimum/maximum are updated annually by INPS).

• Artisans/Traders → INPS Artigiani/Commercianti (fixed quarterly minima plus a percentage on income above the floor).

• Professionals with an Order (lawyers, engineers, architects, etc.) → your professional fund (Cassa) with its own rules.

Contributions are deductible in both regimes. For forfettario, they reduce the taxable base used for the 15%/5% substitute tax—track payments carefully.

7) Activate e-invoicing (SdI) and cross-border reporting

E-invoicing is mandatory for virtually all Partita IVA holders, including those in forfettario. You’ll issue invoices through the Sistema di Interscambio (SdI) using certified software or the free portals.

• Configure your e-invoicing tool and test a self-invoice to validate settings.

• Learn the timing rules: immediate vs deferred invoices (by the 15th of the following month for deferred).

• For foreign clients/suppliers, transmit the required cross-border files via SdI using the designated document types (the so-called “esterometro” flow now travels through SdI).

€2 stamp duty (imposta di bollo).
For non-VAT invoices (common under forfettario) above €77.47, tick the virtual stamp field in the e-invoice; the system totals your quarter and you pay via F24.

8) Set up your invoice template and admin basics

Invoice template essentials:

• Your full legal details (name, address, codice fiscale, Partita IVA, PEC);

• Client details and VAT ID where relevant;

• ATECO code is optional on invoices but useful in proposals;

• If forfettario: add the no-withholding clause and the “operazione non soggetta a IVA” reference under the applicable provision;

• If ordinary: correct VAT rate and nature codes for any non-taxable/exempt items.

Admin basics:

• A dedicated bank account for clarity and to satisfy client vendor-setup checks;

• A secure archive for e-invoice XML/PDF, receipts, and contracts;

• A calendar for F24 due dates, INPS deadlines, VAT liquidations (if ordinary), and stamp-duty quarters.

9) Understand cash-flow before you start invoicing

Forfettario: set aside funds for INPS + 15% (or 5%) substitute tax + regional/municipal add-ons. Because you don’t recover input VAT, large purchases may be more expensive than under ordinary rules.

Ordinary: plan for VAT settlements (often quarterly for small taxpayers), IRPEF advances and balance, and bookkeeping costs. Recovering input VAT improves cash flow if you invest or subcontract early.

If you’ll breach €85,000 turnover, model a switch to ordinary. If you cross €100,000 within the year, ordinary VAT applies from the operation that exceeds—have pricing and systems ready for a same-year changeover.

10) File the right communications when facts change

• Add or change ATECO codes with a variation (variazione) on AA9/12.

• Switch tax regime at year-end following legal windows/conditions.

• Suspend/close activity with AA9/12 (and Registro Imprese if you’re an impresa).

• Update PEC, address, and bank details with clients to avoid rejected payments.

11) Avoid the classic pitfalls new sole traders make

Opening the wrong regime. If your cost base is high or you’ll buy equipment, the ordinary regime often wins once you factor input VAT recovery. Run both scenarios before filing.
Forgetting social-security enrollment. AA9/12 alone is not enough; INPS (or your Cassa) enrollment is mandatory from the start date.
Late e-invoicing. SdI timestamps matter; configure reminders for issue and transmit deadlines.
Missing the €2 stamp duty flag. The liability remains even if you forget the tick—set an automatic rule in your software.
Assuming “occasional” still applies. Once continuity is evident (marketing, recurring clients), you’re expected to open; sticking to occasional receipts can cause back-assessments.
No cash buffer for advances. Italy uses advance payments (acconti) on tax and contributions; your second year often carries both balance for year 1 and advances for year 2.

12) Your first-month checklist (copy-paste and tick off)

• SPID/CIE credentials working; PEC active.

• ATECO chosen; regime decided with numbers.

• AA9/12 filed; Partita IVA issued and protocol saved.

• If impresa: Comunicazione Unica done; Registro Imprese position visible; SUAP/SCIA filed if required; INAIL where applicable.

• INPS (or Cassa) enrollment confirmed.

• E-invoicing tool configured; esterometro document types ready; €2 bollo auto-flag set.

• Invoice template finalized (forfettario clause or VAT details as appropriate).

• Bank account ready; standard proposal/contract templates set with correct fiscal wording.

• Compliance calendar created: F24, INPS, VAT (if ordinary), bollo quarters, and the annual return window.

With these steps, your Partita IVA will be fully operational, compliant, and ready to bill—without rework or last-minute scrambles when the first client asks for an electronic invoice.
