I see on one of the pages that the business income tax is 17% and individual income tax is progressive (up to 40%), VAT is 19%. Then you have some weird "general tax on payments abroad" that's 35%, "license fees" 30% and "advisory services" 30%, "interest on loans" 4%-35%.
In the double taxation paragraph, dividends are taxed at 15% so I guess these aren't one of those amounts where the 35% "general tax on payments abroad" applies. That is assuming they allow you to send dividends abroad.
I guess this isn't seen as important since a startup is mostly burning cash (ie. the $40.000 grant and some?) but it just seems odd to me to just move 1 year in Chile without understanding all these rules and more.
