Moving from France to Spain

You do not say if you are EU nationals or not

That makes a big difference.

Assuming you are UK national

You have the right to live in Spain.  In your situation you need, as a couple, to prove annual income of about 9,000 euros, savings of that amount or the ownership of a property

You need 100% medical cover with no co-payments and no excess charges.

That’s it.

You will need to register within the first three months of moving to spain.

With brexit looming those conditions may change if you do not register before the end of the transition period.

Thanks for that info. We are UK nationals, my son seems to think if we had French citizenship, it would go in our favour!? Any thoughts?

The rules of residency in spain apply to EU Nationals. And as we know we must all be treated equally.

However, as I said, after the transition period uk nationals will not be EU nationals so, logically, unless a special deal is done, they will be treated as non EU. 

My wife is non EU, so I know how much more demanding the requirements are for them.

Good morning

As self-employed you have to pay a social security fee but you can have 80% deduction on the first year, 50% from month 13 to 18 and 30% from month 19 to 24th.
Concerning the taxes you will pay VAT and Income tax on the profit.
