To make a payment online, you can use a US Credit card. Go to www.eloscabos.gob.mx/ In the top right corner, click on language: ENGLISH. Next, scroll down the page and click on link for Property Tax Payments. Then, on the next page you will need to enter your Clave Catastral number in the box that says "Asigna la clave catastral. This is a 17 digit number. Do not enter dashes. Then your statement will appear. Click the red box that says "Pago en Linea" to make a payment. A new page will appear asking for your credit card information. If your payment is not accepted, I would recommend calling your credit card company. My payment was not accepted the first time I tried. I called my credit card company and they accepted the payment while I was talking with them. The credit card company had to acknowledge the payment because it was out of the USA.
After payment is accepted, you will see a PDF of your Probante de Pago. Print this page! It is your receipt of payment. If you have not received this page, you need to try again because most likely your payment was declined.
I would recommend paying your Property Taxes in January as you will receive a 20% discount. If you aren't able to make a payment in January, pay no later than March 31st or you will receive a penalty.
