I'm considering moving to Spain and one concern is taxes since as per US law, I'll still have to pay US income tax.
1. Is Spain like Canada where I only have to pay the difference? (So if I'm paying 17% US income tax and Canadian income tax is 25%, then I'm only on the hook for 25-17% = 8%)
2. What does the income tax look like? Federal? and also local? Any other non-trivial taxes?
3. Do I still need to pay taxes if I continue to work (remotely) for a US-based company?
