Hello, I am Keith one of the experts on Just Answer and happy to help you with your question.
You most certainly are liable to Spanish Income Tax. Here is a very useful summary from AngloInfo:
'You will become liable for tax as a resident of Spain if:
- a) You spend more than 183 cumulative days in one calendar year in Spain i.e. 1st January to 31st December, which is the tax year. You will become liable whether or not you formally register in the Registro Central de Extranjeros or
- b)Your centre of economic interests is in Spain, i.e. the base for your economic or professional activities is in Spain or
- c) Your centre of vital interests is in Spain, i.e. your spouse lives in Spain and you are not legally separated, and/or your dependent minor children live in Spain.
In Spain, an individual is either resident or not resident for the whole tax year. Part-year tax residency is not part of the Spanish system.
As As a resident of Spain you will be liable for tax on your worldwide income at scale rates after any available allowances and deductions'
So there you are, simple, as the Meerkat in the TV advert would say.
All is not lost though as through the Double Taxation Convention between the UK and Spain any tax deducted by the UK is allowed as a tax credit against any Spanish tax liability on the same income stream so you are not taxed twice. However, the Convention does not protect you from differences in rates of taxation.
I do hope that this answer has been useful to you. You may well have to employ a local agent in Spain in this matter.
