Starting a company in Italy: Partita IVA and the Forfettario regime
Opening a business in Italy usually involves obtaining the Partita IVA — the tax number required to issue invoices and operate as a self-employed worker or entrepreneur. This guide explains when a Partita IVA is mandatory, how the forfettario regime works, tax obligations and alternatives, with practical information for Brazilians of Italian descent interested in starting a venture in the country.
What is Partita IVA and how to open it
The Partita IVA is the tax identification number that allows you to issue invoices, deduct costs where applicable, and meet tax obligations in Italy. It is required for self-employed professionals, freelancers, sole traders, and companies, depending on the activity and turnover.
When you need to open a Partita IVA
- When providing services or selling goods on a habitual basis with revenue expectations.
- When the activity requires issuing invoices to clients (companies, professionals, foreign customers).
- When registering with a professional pension fund (cassa previdenziale) or when operating as a sole proprietor registered with the Chamber of Commerce.
Basic steps to open with the Agenzia delle Entrate
- Choose the legal form: autonomous worker (libero professionista), ditta individuale, or a company (SRL, SAS, etc.).
- Identify the ATECO code that describes the economic activity.
- Fill out Form AA9/12 (for individuals) or Form AA7/10 (for companies) and submit to the Agenzia delle Entrate — procedure can be done in person, by proxy, or online via the Agency’s website. Source: Agenzia delle Entrate (https://www.agenziaentrate.gov.it).
- If necessary, register the activity with the local Camera di Commercio and enroll in social security (INPS) and any professional funds. Source: Camere di Commercio (https://www.camcom.gov.it), INPS (https://www.inps.it).

Forfettario regime: characteristics, advantages and limits
The forfettario regime is a simplified tax regime intended for taxpayers with small to medium-sized activities, which streamlines taxes and accounting obligations.
Characteristics and advantages
- Simplified taxation with a substitute tax applied on a taxable base calculated using revenue coefficients (instead of real profit).
- Fewer formal accounting obligations: VAT does not need to be accounted for on each invoice (subject to exemption rules), and ordinary accounting is not required.
- Possibility of applying a reduced substitute tax rate (the rate and any reductions vary according to current law). For updated values and percentages, consult the Agenzia delle Entrate. Source: Agenzia delle Entrate (https://www.agenziaentrate.gov.it).
Revenue limits
- Access to the Forfettario regime is conditioned on an annual turnover cap. Since values and rules can change, always check the current text on the Agenzia delle Entrate website before starting activity. Source: Agenzia delle Entrate (https://www.agenziaentrate.gov.it).
How the tax and social contributions are calculated
- The taxable base is obtained by applying a profitability coefficient (dependent on the ATECO code) to the annual turnover; on this base, the substitute tax is applied at the rate defined by current regulations.
- Social security contributions (INPS) are typically due; self-employed individuals and sole traders under the Forfettario regime pay INPS according to the rates and minimums applicable to their previdential form (gestione separata or professional funds). Source: INPS (https://www.inps.it).
- In many cases there is no VAT charged on issued invoices, but it is essential to verify exemption rules and implications for clients who need to reclaim VAT.
Who can join and how to opt in
- Eligible are taxpayers who meet turnover limits and do not fall under exclusion criteria (for example, equity participations or expenses for dependent work and other conditions set by law).
- The choice to join the forfettario is usually communicated when opening the Partita IVA or in the start-of-activity declaration; for already operating taxpayers, the option is made in the income tax return and follows the procedures indicated by the Agenzia delle Entrate.
Accounting and tax obligations under the Forfettario regime
Despite simplification, the Forfettario regime requires attention to minimum obligations and proper invoice issuance.
Annual obligations and declarations
- Filing the income tax return (Modello Redditi PF or equivalent), indicating the Forfettario regime.
- Payment of substitute taxes and INPS contributions within the deadlines (instalments and settlements, when applicable). Source: Agenzia delle Entrate; INPS.
Invoices, receipts and deductible expenses management
- Issue an invoice with the regime indicated (for example, “forfettario regime, art. …” where required) and without VAT, if applicable.
- Expenses are not deducted according to actual cost as in the ordinary regime; deductibility is implicitly considered when applying the profitability coefficient. Still, keep receipts and documentation for expense proof and potential tax audits. Source: Agenzia delle Entrate.
VAT and exemptions cautions
- In most cases, Forfettario taxpayers do not charge VAT on invoices: this means they cannot reclaim VAT on purchases.
- Pay attention to relationships with corporate clients that require invoices with VAT or specific regimes (for example, intra-EU operations). In cases of intra-EU sales, different obligations may apply; consult the Agenzia delle Entrate. Source: Agenzia delle Entrate.
Alternatives to the Forfettario regime and previdential impacts
For activities with higher turnover or a corporate structure, there are alternatives to the Forfettario that involve more complex accounting but broader deduction possibilities.
Ordinary regime and other tax foundations
- The Ordinary regime involves ordinary accounting, calculation of real profit, VAT collection and deduction, and applying IRPEF rates (for individuals) or IRES/IRAP (for companies). It is suitable for those with high expenses that would offset the loss of simplification.
- For companies (e.g., SRL) there are different corporate and tax rules: IRES, IRAP, corporate obligations and balance sheets. Source: Agenzia delle Entrate; civil Italian regulations.
Impact on previdence and retirement
- Choice of framework (INPS separate management, professional funds, or contributions as a business owner) affects contribution calculations, pension rights, and previdential benefits. Check rates, maximums and contribution periods with INPS or the applicable fund.

How to plan the initial budget
- Estimate revenues and expenses (rent, tools, software, marketing).
- Calculate expected taxes and contributions for both regimes (forfettario vs ordinary).
- Consider setup costs, potential accounting fees, and integration with previdential funds.
- Maintain a financial reserve for tax prepayments and settlements throughout the year.
Practical steps, common mistakes, and support resources
For Brazilians of Italian citizenship or residency, some practical steps and cautions are important.
Practical steps for those who already have Italian citizenship or residence
- Obtain an Italian codice fiscale and, if resident, register with the local municipality (anagrafe) of residence.
- Evaluate the appropriate legal form and previdential framework before opening the Partita IVA.
- Seek updated information from the Agenzia delle Entrate and the local Camera di Commercio. Sources: Agenzia delle Entrate; Camere di Commercio.
Common mistakes when opening a business in Italy and how to avoid them
- Opening a Partita IVA without evaluating the most advantageous tax regime.
- Underestimating social contributions or administrative costs.
- Not verifying sector-specific requirements (licences, sanitary authorizations, local regulations).
- Not consulting a specialized accountant (commercialista) in Italian tax law to plan the best structure.
Support resources: consultancies, chambers of commerce, and official platforms
- Local Chamber of Commerce for business activity registration: Camere di Commercio (https://www.camcom.gov.it).
- Tax information and forms at Agenzia delle Entrate (https://www.agenziaentrate.gov.it).
- Previdential information and contributions at INPS (https://www.inps.it).

Conclusion Opening a business in Italy requires decisions about the legal structure, fiscal framework, and previdential arrangement. The Forfettario regime offers simplification and advantages for micro-enterprises, but its usefulness depends on turnover, expenses, and previdential goals. Before opening the Partita IVA, it is advisable to consult the Agenzia delle Entrate, INPS, and a commercialista to confirm limits, rates, and updated obligations.
