As you needed to complete forms when you left, you will need to fill in forms
when you return. The easiest way is to contact the consulate where you are registered
to sort out your situation. You will have to establish a fully detailed inventory
of your furniture. A moving form attestation is often demanded when you pass
the border (you can ask for it at your Consulate).
You will have to think about school registration if you have children.
Apart from the obvious things that you have to do before moving out of Italy,
there is a long list of authorities and other entities that you need to contact
to inform them of your departure. You cannot assume (unless assured otherwise)
that any one authority, such as your Comune, will notify them on your
behalf. These include:
- Tax authorities
- Commune: check whether this includes refuse collection.
- Inform change of residence to any local entity not informed by Comune, utilities
in particular (electricity, gas, telephone etc). Remember to ask for any deposits
back. The same applies to your condominium/landlord.
- Your bank(s) and any related credit card companies
- Questura
- INPS (get an up-to-date statement of contributions made)
- USL
- Clubs and associations
- Magazine and other subscriptions
- Motorizzazione driver's license
Generally speaking, you can phone a utility and give a final meter reading.
You can write to clubs, associations and magazines. You are best to visit the
bank and Comune. Other places may require either your physical presence,
an autocertification or a letter. Call them to find out. Presumably they will
all want to know your new address as well. Leaving rented property is subject
to it being left in "good condition"; inspect the property together. If there
is a dispute, contact the local branch of SUNIA (Sindacato Unitario Nazionale
Inquilini e Assegnatari), the tenants' union.Normal wear and tear should be
acceptable. 99% of Italians are going to redecorate before they move into a
place in any case.
