If you’re planning to do business with a company in Chile, there are a few key things you should understand to avoid surprises and operate smoothly.

1. Every Chilean company has a RUT

The RUT (Rol Único Tributario) is the unique tax ID number assigned to every company (and person) in Chile. It’s essential for identifying a business legally and financially. If you’re going to sign a contract, issue an invoice, or even just verify who you’re dealing with, you’ll need to ask for their RUT. Think of it as the Chilean version of a tax ID or business registration number.

2. The SII: Chile’s Tax Authority

Chile’s tax system is managed by the SII (Servicio de Impuestos Internos), and their official website is www.sii.cl. This is the equivalent of the IRS in the United States. All companies in Chile are required to submit their tax declarations here, both monthly and annually.

3. What is the “Carpeta Tributaria”?

One of the most important documents you can ask for when evaluating a Chilean company is the Carpeta Tributaria, which is essentially a tax folder. This is a PDF that includes:

  • Summaries of the company’s annual tax declarations
  • Monthly VAT (IVA) declarations
  • Key financial indicators
  • Basic company details and tax history

Many Chilean companies share this document when they are being evaluated as providers, partners, or clients. While it contains valuable data, it’s not easy to interpret—especially if you’re not familiar with Chilean tax forms or if Spanish is not your first language.
