If you get your TIE this year, you will be liable for income tax in Spain for Jan-Dec 2021, and you will "reconcile" in 2022.
You may find that the Spanish tax-take is higher than in the UK (depending on your circumstances).
"Reconcile" - you will make a Modelo 720 declaration of worldwide assets in Feb 2022. You will submit your tax return to the Spanish authorities in June 2022. You will pay tax for Jan-Dec 2021 in June and November 2022 (roughly a 60/40 split between the two payments). But here is the kicker .... you will continue to pay UK tax as well for UK-derived income. So you will pay UK tax (PAYE) and then the Spanish tax as well. So there is a significant cash flow issue to plan for. You will then claim back your UK tax from the UK. This reclaim process will start in September 2022.
