Pension

If you're resident then it's potentially taxable wherever you have it paid be that UK or Spain or anywhere else.

Your worldwide income must be declared but if you get less than about €18,000 then you will fall below the threshold and there will be no to pay, you must still declare at least in the first instance to get yourself properly registered in the Spanish tax system.

Ty for your help, 

It's also important to do that first tax return as if you are below the threshold it's that which will (eventually) trigger you getting free medicines instead of having to pay 10%!

A word of caution my other half has a UK state pension and total income well below 18000€ and last year had to pay tax.

The following quote is taken from the link below where you will find more detailed information:

'If a natural person is a tax resident in Spain, he or she is liable for Personal Income Tax (IRPF) and must pay taxes in Spain on his world income , that is, he must declare in Spain the income obtained anywhere in the world, without prejudice to the provisions of the Convention to avoid international double taxation signed between Spain and the country of origin of the income.'

I have a state pension which I have to pay tax on, here in Spain as a Spanish resident, at my age 75 my tax allowance is € 8100 and then 20 %.

Sorry my error, the threshold is around €13,000 not 18,000

I’m just below that but I didn’t pay any tax last year but I think for this year with the pay raise on state pension so come June I might this time.

Hello

I earn 7000€ a year and never had a free prescription.  It's always been about 10 per cent.
