Generally, if you are in Spain for less than 183 days per year, you are not considered a resident for tax purposes. However, there are exceptions. For instance, if your spouse and children live in Spain. Or if the Spanish tax office believes that your core economic interests are in Spain, although this is difficult to determine. If you are unsure of your tax liabilities you can also arrange a personalised report with our tax advisors. This is a separate service. We will offer it to you once you complete the form.
