IMI (council tax) - Bills are usually sent out during March, for payment during April.

IRS (personal income tax) - tax return relating to income earned between 1 Jan and 31 Dec of previous year, to be submitted between 1 April and 31 May. Bill usually received during August, with a payment limit date some 4-6 weeks later.

Well it depends on your personal financial circumstance whether any earnings-related taxes other than IRS apply to you/your business. Remember, as a resident in Portugal, you must declare all income earned worldwide.

If you’re going to apply for NHR tax status, you must do this before the 31st March of the year following the year in which you became resident I.e. if you become resident in PT this year (2018) you must apply for NHR status by 31st March 2019 and submit your first IRS tax return in Portugal between 1 April - 31 May 2019 for income earned during 2018.

Erm...I suppose IUC/vehicle tax - paid during the same month each year as the month in which your vehicle was originally registered. And the annual IMT test/MOT must be carried out by the anniversary of the exact date that your vehicle was registered, although I think you can take it for test up to 3 months in advance, and the test date for the next year won’t change, so can effectively get a 15-month IMT, if I’m correct. It’s definitely at least 2 months early.

Other deadlines:
After 3 months (or before) and before end of 4 month - get residence
Inform AT/Finanças that you are now resident (if you were previously non-resident with them) within 60 days of gaining residencia
By end of month 5 register your overseas driving licence at local IMTT office (DVLA)
With residencia you can register for state healthcare at centro de saude (also take NIF and passport). If you are in receipt of a UK state pension you will have to provide Social Security with a completed S1 form from UK, I believe. Otherwise, straight to the health centre you go.

Of course it is, thank you. Doh!!

Just bringing this alive again..... “By end of month 5 register your overseas driving licence at local IMTT office (DVLA)”, I seem to read differing opinions and info on this. Could anyone explain what happens... most importantly do you lose your uk licence and acquire a Portuguese one?

If it helps clarify, I would like somehow to get my Portugal licence to allow me to buy and own/drive a car in Portugal as I’m now resident but would also like to keep my uk driving licence for use every other month when I’m in the uk for 3weeks with work, all suggestions welcome
