Registering Your Business with the Rome Chamber of Commerce: Step-by-Step Guide
Sole trader, SRL or craft business: how Italy's ComUnica filing works, how much it costs and what happens if you skip the Artisans' Register.
In a nutshell
Anyone opening a commercial, craft or company-based business in Italy must register with the Registro delle Imprese (Italy's official Business Register), held by the Camera di Commercio (Chambre of Commerce — the provincial body that oversees business registration and trade matters) of the province where the business is based. In Rome that is the CCIAA di Roma (Via dell'Umiltà 48). Registration is done entirely online through a single filing called ComUnica, which simultaneously notifies the Chamber of Commerce, Agenzia delle Entrate (Italy's tax-revenue agency), INPS (Italy's social-security agency) and INAIL (Italy's workplace-injury insurance institute).
Important: purely self-employed professionals (liberi professionisti) — lawyers, doctors, engineers — who operate only with a Partita IVA (Italian VAT number — required to invoice as a self-employed worker) and membership of their own professional body do not register with the Chamber of Commerce.

What registration gets you
The Registro delle Imprese is Italy's public archive of all businesses. Registering:
- Makes your business officially recognised by the state
- Gives legal personality to an SRL or SPA (without registration, a company does not legally exist)
- Makes your business information publicly searchable (address, business purpose, directors)
- Fulfils a legal obligation for commercial, craft and agricultural businesses
You also receive a numero REA (Repertorio Economico Amministrativo — your business's administrative identification number), which appears on all your tax documents.
Who must register — and who doesn't
The following must register: sole traders in commerce (shops, e-commerce, cafés, restaurants), sole traders in craft trades (plumbers, hairdressers, electricians, carpenters), all companies (SRL, SNC, SAS, SPA, cooperatives) and agricultural businesses.
Craft businesses must also register on the Albo Artigiani (Artisans' Register), which is a special section of the Business Register. This is not optional — if your activity falls under the definition of artigianato (craft trade) set out in Legge 443/1985, you are legally required to register there. Doing it through ComUnica costs nothing extra.
Exempt from registration: self-employed professionals with a Partita IVA and a professional-body membership, occasional freelancers, and certain small farmers.
ComUnica: one filing, four agencies
ComUnica (Comunicazione Unica, introduced by Legge 40/2007) lets you open your business by submitting a single online filing that is automatically routed to four bodies:
- Camera di Commercio — entry in the Business Register and, if applicable, the Artisans' Register
- Agenzia delle Entrate — opens your Partita IVA with the correct ATECO activity code
- INPS — enrols you in the craft-trades or commerce social-security scheme
- INAIL — creates your workplace-injury insurance position
The filing is submitted through registroimprese.it, accessed with SPID or CIE.
How to file ComUnica: step by step
Before you start, you need an active PEC (posta elettronica certificata — certified email, legally equivalent to registered mail in Italy) registered on INI-PEC, and a firma digitale (qualified digital signature). Without these two tools the filing cannot be submitted.
Step 1 — Preparation
Decide on your legal form (sole trader, SRL, SNC…), choose the ATECO code that matches your activity, and check whether you need specific qualifications or licences. For example, anyone working with food must hold an HACCP certificate and the SAB qualification (formerly REC) to serve food and drink. Beauticians and hairdressers need their relevant professional diploma.
Step 2 — Online filing
Go to registroimprese.it, log in with SPID or CIE, open the "ComUnica" section and create a new filing. Select CCIAA Roma as the competent office and complete the required forms: I1/I2 for the Business Register, AA9/12 for the Agenzia delle Entrate, plus the INPS and INAIL forms. If you are a craft trader, add form S for the Artisans' Register.
Attach your ID and, if you are forming a company, the atto costitutivo (articles of association). Sign the filing with your digital signature and pay the fees by card or through the Telemaco payment system.
Step 3 — CCIAA Roma response
A standard filing is processed within 5 working days. If you submitted a SCIA (Segnalazione Certificata di Inizio Attività — a certified notice of commencement), the filing takes immediate effect: you can start trading from the moment you submit. You will receive your visura camerale (Chamber of Commerce certificate) containing your REA number, and the data is automatically forwarded to the other agencies.
Costs by legal form
| Item | Sole trader | Simplified SRL | Standard SRL |
|---|---|---|---|
| Business Register stamp duty | €17.50 | €156 | €156 |
| CCIAA secretarial fees | €18 | €90 | €90 |
| Registration tax | — | €200 | €200 |
| Notary | — | €200–400 | €1,500–3,500 |
| One-off total | €35.50 | €665–1,165 | €2,565–4,715 |
On top of this, there is an annual CCIAA Roma fee, due every year by 30 June:
| Category | Amount |
|---|---|
| Sole traders on the flat-rate tax regime (forfettario) | €88 |
| Sole traders on the standard regime | €120 |
| SRL (turnover up to €100,000) | €120 |
| SRL (turnover €100k–€250k) | €200 |
Use the CCIAA Roma calculator to find your exact figure.
If you want an accountant (commercialista) or labour consultant (consulente del lavoro) to handle the filing for you, typical fees in Rome are: €80–200 for a sole trader, €300–600 for a simplified SRL.
Mistakes to avoid
- Filing ComUnica without an active PEC. CCIAA Roma will verify that your PEC is registered on INI-PEC. If it isn't, the filing is rejected.
- Skipping the Artisans' Register when you run a craft business. It is not optional. If your activity falls under Legge 443/1985 and you don't register, you face fines and a retroactive registration obligation.
- Forgetting the annual fee. The deadline is 30 June each year. Late payment attracts a 30% penalty plus interest.
Special cases
Non-EU foreigners: opening a business requires a residence permit that authorises self-employment. If your country of origin does not have a reciprocity agreement with Italy, you can apply for a certificazione attributiva dei requisiti (certificate of eligibility) directly from CCIAA Roma.
Innovative start-ups: there is a special section of the Business Register (DL 179/2012) with free registration and no annual fee for the first four years. Requirements relate to the innovative nature of the business, R&D expenditure and the holding of patents. The dedicated portal is startup.registroimprese.it.
Change of address or ATECO code: submit a new ComUnica using form I2 (variation). The cost is approximately €17.50 in stamp duty plus €30 in fees.
Closing down: submit a ComUnica cessation filing. For companies, there are two distinct phases: liquidation first, then formal cancellation.
