For Americans considering moving here long-term: the 183-day rule (becoming a Colombian tax resident) is the big inflection point. Once you're a Colombian tax resident, you owe Colombian tax on worldwide income (with US-Colombia treaty offsetting some).

Real implications:

• First-year visitors who exit before 183 days: no Colombian tax exposure
• Long-term arrivals: plan for tax residency in year 2 onward
• Crypto/investment income: gets complicated, get a real accountant

This is the thing nobody talks about until year 1.5 and then everyone panics.
