Have you been granted Residencia TIE yet ? This is the starting point.
Spain's tax year is 1 Jan-31 Dec.
We were granted Residencia in Aug 2018, so we became liable for income tax in Spain on 1/1/19.
We submitted our Modelo 720 forms (declaration of worldwide assets) in Feb 2020. We submitted our income tax return (we "reconciled" tax) for Jan-Dec 2019 in June 2020. We paid the Jan-Dec 2019 tax in 2 chunks ... June and November 2020.
If you gain Residencia/TIE in period Jan-June, you reconcile the following year.
If you gain Residencia/TIE in period July-December, you reconcile a year later.
It has been suggested that the date of your padron (usually before Residencia/TIE) can be applied by the Spanish tax authorities as the starting point, but I don't know anyone who has experienced this.
You have to pay your Spanish income tax before you claim back UK income tax for the same period. We are still paying tax PAYE in the UK. We have applied to receive our tax (since 1/1/19) from the UK, but we have not received it yet. This seems to be quite normal.
So beware, there is a tax cashflow pinch-point to plan for.
