General VAT information for Chile
Businesses are not currently obligated to send and receive invoices electronically when dealing with other businesses. However, as per the amendment to the Law on Accounting, a mandate is on the way.
While mandatory B2B e-invoicing will not take effect until 1 January 2028, businesses can submit B2B e-invoices to the eAddress system voluntarily starting from 30 March 2026. If they choose to issue e-invoices, the issuer must ensure the integrity of the content and the authenticity of the origin by, for example, using an electronic signature.
A B2B e-invoicing mandate has been in development for years and has been subject to several postponements. Most recently, in June 2025, the commencement date of the obligation was delayed from 1 January 2026 to 1 January 2028.
