\# VAT considerations in Colombia VAT (\*\*Value Added Tax\*\*) is a tax burden that applies to the sale of products or the provision of services within Colombian territory. Some products and services are excluded from VAT and others have reduced rates. Currently, the \*\*general rate for this tax is 19%\*\*. ## Taxes in online payments To process VAT correctly, you can send the net amount (\`unit\_price\`) and VAT (\`taxes\`) when making the charge through the API. > RED\_MESSAGE > > The \`taxes.value\` parameter must be completed only with a integer numeric value.
