Fines for Not Updating Your Tax Address in the RFC and How to Avoid Them

Tax Address in Mexico: What It Is and Why It Must Be Kept Updated

The tax address in Mexico is the location that allows the Tax Administration Service (SAT) to find you for tax purposes. The definition may vary depending on the type of taxpayer:

• If you are registered as an individual, it would be your primary residence.

• If you register as a legal entity, it is the place where your business is managed.

Why should you keep it updated?

The tax address in Mexico serves as a reference point for tax audits. Like the Tax Mailbox, it’s necessary for receiving notifications or summons from the SAT. It’s the address they will visit in case of audits, if needed.

Is it the same as the commercial address?

Not necessarily.

The tax address is the one you register with the SAT and has legal and tax implications, whether as an individual or a legal entity. The commercial address, on the other hand, is the location where your economic activity takes place.

What happens if you don’t update your tax address in the RFC?

Filing your annual return late is not the only reason you can be sanctioned. Any change you make to your RFC and do not report to the SAT is grounds for a fine.

How much is the fine in 2025?

According to Article 80 of the Federal Tax Code, the fine amount varies depending on the infraction. Let’s look at each one and the applicable ranges:

• Not reporting the change of tax address or doing so after the legal deadline. In this case, the fine ranges from $5,400 to $10,780 MXN for most taxpayers. For those under the Simplified Trust Regime (Régimen Simplificado de Confianza), the fine ranges from $1,800 to $3,600 MXN.

• Registering an incorrect address. If you declare a false address, the fine can range from $4,480 to $13,430 MXN.

What is the deadline to update my tax address in the RFC?

You have 10 business days to submit the notice of change of tax address to the SAT. This period starts from the day the change occurs—for example, when you move.

• Note: You can avoid the fine for failing to report the change if you update it spontaneously—meaning without the SAT requesting it. This exception is mentioned in Article 79, Section III of the CFF.

Additional consequences of not updating your tax address in the RFC

Receiving a fine for a transfer or for not updating your tax address in the RFC is a monetary consequence. However, it’s not the only negative effect, as:

• Your Digital Seal Certificate (CSD) may be temporarily restricted. This would prevent you from issuing valid invoices, which is bad for any economic activity you conduct.

• Your RFC could be suspended, leaving you unable to operate officially.

• Tax refunds or other important tax procedures could be blocked.

• If they visit and cannot find you at the registered address, the SAT may consider it non-compliance. The same applies in the case of desk audits or any enforcement procedure.

If they visit you and cannot find you at your registered address, the SAT could consider this a breach. The same applies in the case of cabinet reviews or any other audit procedure.

How to Update My Tax Address Step by Step

To avoid any issues with the SAT, you only need to take a few minutes out of your day to update your information.

Here are the steps for the process:

1. Go to the SAT portal and select the “Procedures” option.

2. Locate and click on “RFC,” then select “Change of address or Update information in the RFC.”

3. Log in with your RFC and password or valid e.firma.

4. Enter the details of your current tax address as required by the form. If there are changes to your phone number, street name, or numbering, be sure to register them.

5. Verify that all fields are correct and click “Continue.”

6. Sign the process with your e.firma and then submit it to complete the procedure.

7. A “Notice of update of tax status” will be generated, which you can download and keep as proof.

Many SAT procedures can be done online, including recovering SAT certificates. But if you want to submit changes in person, you can also do so—though it must be by appointment and with all required documents.

What to Do If You’ve Already Been Fined

If you receive a fine for not updating your tax address in the RFC, do the following:

• Update your tax address as soon as possible via the SAT portal.

• If you believe the fine was unjustified or an error occurred, file a clarification either online or by scheduling an in-person appointment.

• If the fine is justified, pay it within the indicated period and keep the receipt as proof.

It’s important to verify that your tax status has been successfully updated in the SAT portal to avoid misunderstandings and further sanctions.

Make sure to check for fines or debts with the SAT so you can act immediately.

Conclusion

Ignoring the update of your tax address in the RFC brings legal and financial consequences. Besides a fine, you could be excluded from the system, lose refunds, and even face more severe penalties for inconsistencies.

These are reason enough to stay up to date with your information.

Frequently Asked Questions

Can I challenge an SAT fine for an incorrect tax address?

Yes. You can do so as long as you have sufficient proof of your actual address. This can include utility bills, lease agreements, or some form of official proof that supports your tax status and can be presented.

What if I live in a place without a formal address or official numbering?

You can register a virtual office with legal tax validity or request an address certificate from a local authority. But you must ensure that the space is related to your economic or administrative activity.

Does the fine apply if I am an individual with no economic activity?

No. If you are registered in the RFC but have no economic activity and do not generate income, you are not obligated according to the SAT. You also do not have to file returns, so the fine does not apply in these cases.
