🪪 What Is the RUT in Chile and Why Is It Easier to Obtain If You Are a Mercosur Citizen?

If you’re planning to live or work in Chile, you’ve probably heard about the RUT.

But what is it really?
Is it only for companies?
Is it the same as an ID card?
And why is it easier to obtain if you are a Mercosur citizen?

Here we explain it clearly.

📌 What Is the RUT in Chile?

RUT stands for Rol Único Tributario (Unique Tax Identification Number).

It is Chile’s unique identification number.

And here is the key point:

In Chile, the RUT identifies both individuals and companies.

There is no separate number for civil identification and tax purposes.

It is the same system.

🔎 What Is the Difference Between the RUT and the ID Card?

Many people think they are different things. Not exactly.

• The RUT is the number.
• The ID card is the physical document where that number appears.

When someone says “I need to get a RUT,” what they actually need is to obtain their Chilean ID card.

That ID card includes their assigned RUT number.

🏢 Do Companies Also Have a RUT?

Yes.

In Chile:

• Individuals have a RUT.
• Companies also have a RUT.

The difference lies in the holder:

Individual → The RUT appears on their national ID card.
Company → A RUT is assigned through the Chilean Tax Authority (SII), along with a legal representative and tax obligations.

It is a unified system for everyone.

🌎 Why Is It Easier If You Are a Mercosur Citizen?

If you are a citizen of a Mercosur country or an associated state, the process to obtain your Chilean ID card (and therefore your RUT) is simpler than under other immigration categories.

This applies to citizens of:

• Uruguay
• Argentina
• Brazil
• Paraguay
• Bolivia
• Peru
• Colombia
• Ecuador
• Among others

The Mercosur agreement allows you to apply for temporary residence with basic requirements and without needing to prove a prior employment contract or high income.

In most cases, you will be asked for:

• A valid ID or passport
• A criminal background certificate from your home country
• A Chilean address
• Payment of the corresponding government fee

Once you are eligible to apply for your ID card at the Civil Registry, your RUT number is automatically assigned.

There is no separate procedure to “apply for a RUT.”

⚠️ What Many People Don’t Know

Even though the Mercosur process is more accessible, it is important to:

• Submit documentation correctly
• Avoid mistakes in your application
• Update your tax address if you plan to work
• Properly register business activities if you will issue invoices

This is where issues usually arise.
