Capital Gains Tax

Hi All
We will be applying for residencia in 2025 and moving permanently into what is now a holiday home.

We have had a lot of work done on the property which will have added a considerable amount to its market value.

The house will be our main residence although we will be keeping a small flat back in the UK.

If we come to sell our main residence in Spain to, possibly, downsize in the future, would we be subject to capital gains or any other taxes.

We will obviously seek financial advice before or during our residencia application but it would be useful to have a broad idea of what taxes might apply to any future house sale.

Thanks in advance.

Thanks Marcliff. That's really helpful

Can we deduct the cost of the improvements from the profit? Do we have to have invoices to prove the costs?

Perhaps getting into too much detail for now, but if anyone knows....
