This conversation is going in circles because it mixes three different things that are not the same.
Tourist status is an immigration concept.
Tax residency is a factual assessment.
“Low profile” is not a legal category anywhere on this planet.
Visa runs do not reset tax facts. Staying a few months as a “tourist” while living, sleeping, consuming, and centering your life in a place creates habitual abode and center of vital interests issues regardless of what stamp is in the passport. Every OECD country applies this. Many non-OECD countries quietly apply it when money comes to surface or when another authority asks questions.
“Invisible income” is not invisible. Crypto exchanges report. Onramps report. Offramps report. Banks report. Payment processors report. Travel patterns are logged. Telecoms log location. The idea that online income floats in a legal vacuum is 2006 thinking.
“No one chases you for years” is not a defense. Delayed enforcement is the norm, tax reassessments are retroactive, penalties compound. Criminal thresholds are easily crossed and inexorably enforced.
Having a passport or residence somewhere else does not allocate tax by magic. You are not “automatically resident” of a country because you hold its passport. Citizenship and tax residency are separate constructs almost everywhere.
Yes, you can avoid taxes. That requires an actual residency solution, actual substance, actual compliance, and usually actual taxes paid somewhere. What does not work anymore is pretending to live nowhere while living somewhere.
PT as folklore survives. PT as a strategy does not.
