  • People who can access Agenzia delle Entrate with CIE or SPID.
  • People comfortable checking official forms and keeping receipts.

What You Need

  • Codice Fiscale.
  • Fiscal address and activity address.

The File Chain

AA9/12 declaration -> .dch -> .inv -> .p7m -> final receipt

The .dch is the saved declaration. The .inv is prepared inside the AA9/12 software for transmission. During upload, Agenzia Entrate can generate a signed .p7m. The first receipt proves the file was received; the final processing receipt proves whether the application was accepted.

Steps

  • Download the current AA9/12 software from Agenzia delle Entrate for Dichiarazione inizio attivita imprese individuali e lavoratori autonomi.
  • Fill Quadro A with the activity start date, not necessarily the upload date.
  • Fill Quadro B with denomination, ATECO, activity description, expected turnover, activity address and tax regime.
  • Fill Quadro C with personal and fiscal domicile data.
  • Leave Quadri D and E empty unless you have representation, succession, transfer or special cases.
  • Use Quadro G for secondary activities.
  • Fill Quadro I carefully for email, phone, website, property and client type.
  • Mark only the compiled sections, for example A, B, C, G and I.
  • Leave Impegno alla presentazione telematica empty when submitting yourself.
  • Save the declaration as .dch.
  • Use Strumenti -> Preparazione file to generate .inv.
  • Log in to Area Riservata.
  • Go to Servizi -> Trasmissioni telematiche -> Invio documenti -> Invio diretto.
  • Choose Attribuzione partita IVA ditta individuale.
  • Upload the .inv, confirm and save the generated files and receipts.

Correct Document Type

Use:

Attribuzione partita IVA ditta individuale

Choosing a similar-looking document type can lead to rejection or a confusing processing result.

How To Read Receipts

The first confirmation usually contains file name, size, protocol and hash. Treat it as upload confirmation only.

The final processing receipt should show accepted and rejected counts. A successful outcome includes the certificate assigning the Partita IVA number. If rejected, the receipt normally contains the rejection reason.

Common Mistakes

  • Using +39 in the phone prefix field.
  • Uploading the wrong file type.
  • Assuming the first receipt is the final result.
  • Filling intermediary commitment fields when no intermediary is used.
  • Publishing screenshots without redacting IDs, protocol numbers, hashes, address, phone, email and cadastral data.

What To Do Next

  • Verify the Partita IVA.
  • Activate PEC and electronic invoice storage.
  • Register in INPS Gestione Separata if applicable.
  • Prepare the first electronic invoice.
  • Track F24 and annual declaration deadlines.
