Owning property abroad is exciting, but for U.S. citizens, it's a major tax and compliance hurdle. The IRS requires detailed reporting of foreign rental income (Schedule E), and transactions may trigger FBAR (FinCEN 114) and FATCA (Form 8938) filings with steep penalties for non-compliance. Capital gains are taxable, and deductions must be properly managed using forms like the Foreign Tax Credit (Form 1116) to avoid double taxation.
The key mistake is relying on domestic accountants; international real estate requires expertise in both U.S. cross-border regulations and local tax laws (like Spain's GILT tax). Working with a specialized CPA before purchasing can save significant time, money, and legal stress by ensuring accurate, timely filings and simplifying multi-layered compliance.
