What it is
The AT's Form B (Modelo B) is for people who hold a Citizen Card (Cartão de Cidadão) and have already changed the address on the card, but need the effective date with the AT to be backdated. Evidence of the dates must be attached. It can be submitted through the e-balcão online service desk, and the AT assesses the evidence before deciding. The older notes on tax representatives must be read together with the rules in force; you may be exempt if you have signed up for electronic notifications. It does not change the address on the card itself.
