Form AA9/12 is the declaration of start of activity, change of data or end of activity for VAT purposes, for sole proprietors and self-employed workers in Italy.
Use it when you start a business or professional activity and need a VAT number, when details such as your address, activity or representative change, or when you stop the activity. Entities other than individuals use a different form.
Your personal and tax details, the place where the activity is carried out, the business activity code, your tax regime and accounting options, and details of any representative. The form is split into sections for each topic, such as the activity, the place of business and the representative.
The form must be filed within 30 days of the start of the activity, of the change, or of the end of the activity.
