A tax calendar from a PDF

The trigger is bureaucratic clockwork: a new DIAN tributary calendar for 2026 ▸ 1:37. His process starts by making the AI specific instead of generic: upload the company RUT to AI Studio, because the RUT carries the responsibility codes and economic-activity codes that determine what actually applies ▸ 2:04, turn on grounding with Google Search so unknowns get looked up instead of invented ▸ 2:44, and let Gemini act as the in-house DIAN specialist ▸ 2:35.

The audit paid before the calendar did. He is his own accountant, filing everything in zero ▸ 6:40, “ventajas de no tener ingresos, de cero a un millón, literal de cero” ▸ 7:54, and it turns out one of those zeros was unnecessary: the monthly form 350 only applies if you’re withholding IVA or paying anyone above 95 UVT, roughly four and a half million pesos ▸ 6:21, neither of which is true, so he’d been filling an extra form every month for nothing ▸ 6:47.

Saved as .ics, imported into Google Calendar ▸ 9:54, the whole fiscal year is scheduled through next January ▸ 11:32. Two cautions keep it honest: review the file before importing, since he’s never dared test whether the calendar has an undo ▸ 10:09, and the review caught a real drift, the IVA consolidado moved from February 17 to the 16 against last year’s entry ▸ 10:45. A deadline that moved one day is exactly the kind of thing that fines you; it’s also exactly the kind of thing this pipeline exists to catch…
