Sound familiar?

If you've moved countries, tax season is a special kind of hell.

😰

"Do I file in both countries?"

You earned income in your home country AND your new country. Nobody can give you a straight answer on what goes where.

💸

"My CPA quoted me $3,000"

Cross-border tax specialists are expensive. And they still need YOU to figure out half the paperwork.

📋

"What even is Form 8938?"

FBAR, FATCA, T1135, Form 67, SA109... The alphabet soup of cross-border reporting is enough to make anyone panic.
