Do I need to pay Colombian taxes if I work remotely from here?

If you spend more than 183 days in Colombia within any 365-day period you generally become a tax resident, which can mean reporting worldwide income to the DIAN. The details depend on your visa, your home country, and any tax treaty. This is genuinely case-by-case — talk to a Colombian accountant who handles expat taxes, and verify current rules with the DIAN before filing.
