Key Takeaways
- Banamex launched a special promotion for October 2025 to help residents in Mexico pay local taxes and services more easily.
- Eligible payments include property tax (predial), water bills, vehicle tax (tenencia), and registration renewal (refrendo).
- You can pay in a single charge with your Banamex debit or credit card, or split it into interest-free monthly installments (MSI – Meses Sin Intereses) if you use a credit card in person.
- Using a credit card online or through the Banamex App or BancaNet counts as a cash advance, which generates a commission fee and disqualifies the transaction from MSI.
- Always protect your personal data: never share your PIN, passwords, or SMS codes with anyone.
- Before paying, check your state or municipality’s participation on Banamex’s official website.
The October 2025 Promotion — What It Covers
Throughout October 2025, Banamex offers customers the chance to pay essential public services under more flexible conditions. The promotion runs from October 1 to October 31, 2025 — corresponding to 2:00 AM to 7:59 AM Netherlands time because of the time difference.
You can pay:
- Property tax (predial)
- Water service bills
- Vehicle ownership tax (tenencia)
- Vehicle registration renewal (refrendo)
Payments can be made either:
- In a single payment, using Banamex debit or credit cards, or
- Through interest-free monthly installments (MSI) at a 0.0 % fixed rate, exclusive to Banamex credit cards when processed in person.
Banamex clearly states that if you pay using the App Banamex, BancaNet, or BancaNet Empresarial, the operation is treated as a cash advance with a commission. This means you won’t qualify for the MSI benefit.
You can make payments at Banamex branches or authorized government collection offices. Participation and deadlines vary by state and municipality, so checking your location’s availability beforehand is essential.

Staying Safe: How Banamex Warns Against Fraud
The promotional email begins with a strong message:
“Together Against Fraud. Never share your PIN, SMS codes, or passwords.” (translated from Spanish)
Banamex emphasizes that it will never ask for your credentials, NetKey® codes, or verification numbers by email or phone. If you receive a suspicious link or are asked to “update your data,” it’s almost certainly fraudulent.
Always type “banamex.com” manually into your browser rather than clicking any link sent by email or text message.
You can find official safety resources and updates at the bank’s Security Center, which publishes current alerts and fraud-prevention tips.

If You Suspect Fraud
- Block your card immediately via the Banamex App or by calling the number printed on the back of your card.
- Change your passwords right away.
- Check your recent transactions for unusual activity.
- Do not share one-time codes or account details with anyone who contacts you claiming to be from the bank.

How to Make the Most of the Offer
- Pay in person at a Banamex branch or government collection office if you want interest-free installments.
- Use the official Banamex Taxes and Services microsite to verify whether your local government participates.
- Avoid paying with your credit card online, since those transactions generate commissions.
- If you choose to pay in full, consider using your debit card to avoid interest entirely.
- Keep an eye on your card statements to ensure payments post correctly.
- When in doubt, contact Banamex using only verified numbers or links from their official website.
