In Colombia, an individual is a tax resident if he or she stays in the country for more than 183 calendar days within a period of 365 consecutive days, among other conditions (Tax Statute, art. 10), and residents are taxed on their Colombian-source and foreign-source income (art. 9). If you are a resident, what your LLC earns selling on Amazon does not fall outside the Colombian radar: it depends on how the income is classified and how it is received. The controlled foreign entities regime (ECE, arts. 882 to 893) covers companies, trusts, funds and other foreign entities controlled by residents, with or without legal personality and whether or not they are transparent for tax purposes (art. 882, par. 1), but it attributes to the resident only passive income (dividends, interest, intangibles, disposal of assets that generate passive income, real estate; art. 884), and it presumes active income when active income is 80% or more of total income (art. 885). An LLC that sells product with real operations generates, in principle, active income, but the qualification, the place of effective management (art. 12-1) and what happens when you withdraw profits are analyzed case by case. In addition, interests, accounts and inventory abroad form part of your net worth and may oblige you to file the annual return of assets abroad when their value on January 1 exceeds 2,000 UVT, itemizing them individually if they exceed 3,580 UVT (art. 607).
On the exchange-control side, Decree 1068 of 2015 defines as Colombian investment abroad the shares, quotas, rights or other interests in the capital of companies or any type of business located outside Colombia, acquired by a resident, without requiring authorization (arts. 2.17.2.4.1.1 and 2.17.2.4.1.3). Registration is made under article 2.17.2.5.1.1, as amended by Decree 1044 of 2026 (Official Gazette 53,580 of August 6, 2026): a registration declaration of the initial or additional investments, of their changes and of their cancellation is filed with the Banco de la República, and, when the investment is made in foreign currency, the exchange declaration for its channeling through the foreign exchange market serves as the registration declaration. That is why it matters how the money flows between you and the LLC. In the US, for its part, the Supreme Court of that country (South Dakota v. Wayfair, June 21, 2018) eliminated the physical-presence requirement for a state to require a remote seller to collect sales tax, and Amazon states that, as a marketplace facilitator, it calculates, collects, remits and refunds sales tax on third-party sales shipped to states that have that legislation; whether the seller has its own registration or filing obligations, and in which states, is defined by each state and must be confirmed by a professional in the US. We do not give sales tax figures by state here. For the detail of each piece, see declaring a US LLC before the DIAN, the ECE regime and registering the investment before the Banco de la República.
