US–Spain tax guidance

Where Uncle Sam meets
Hacienda.

Living in Spain as an American means two tax systems, two sets of deadlines, and double the confusion. HolaSam brings clarity — so you know what you're dealing with, when to do what, what to ask, and who to call.

Sound familiar?

"Do I have to file a US tax return from Spain?"

Yes, most Americans abroad do. The hard part is knowing what applies, what reliefs may help, and when to do what.

"What even is Modelo 720 and do I need it?"

It's Spain's foreign asset declaration. The rules are easy to miss, and late or incorrect filing can still create expensive problems.

"If I sell my US property, what do I owe Spain?"

Both countries may care. HolaSam helps you identify the questions to ask before a property sale becomes a tax-season surprise.

"My gestor handles Spain. Who helps me understand the US side?"

HolaSam helps you understand both sides — so you can work more effectively with the professionals who actually file your returns.
