This page helps you check Property Tax details in Cameron County, Texas, review payment options, and find the right office for billing, delinquent tax, and appraisal questions. It points you to the Cameron County Tax Office and related county offices so you can use the official process.
The main online starting point is the Cameron County Tax Office search tool. For value, exemption, or mailing address issues, the Cameron Appraisal District handles those updates. This site is independent and does not provide legal, tax, or financial advice.
Cameron County Tax Office search
Start with the county’s online tax search to look up a bill, confirm the amount due, or find a property tax account.
- Bill number or account number
- Owner name as shown on the deed
- Mailing address
- Property address with street number and street name
Use the official search page to match the record you need, then review the billing information shown for that account.
- Open the search and pay taxes page.
- Choose the search method that best fits what you have, such as owner name, account number, mailing address, or property address.
- Open the matching account and review the current bill information before making a payment or contacting the tax office.
If your statement is missing or you need another copy, the tax office says you should request one by mid-December rather than waiting for the due date.
Payment deadlines and delinquent taxes
Cameron County states that tax statements are mailed beginning in October. Taxes are due by January 31 of the following year, and if that date falls on a weekend or holiday, the next regular business day becomes the deadline.
The county also publishes a month-by-month delinquent schedule once taxes go unpaid. The Tax Assessor-Collector says penalty and interest cannot be removed or adjusted by that office.
| Time period | Penalty | Interest | Total added |
|---|---|---|---|
| February | 6% | 1% | 7% |
| March | 7% | 2% | 9% |
| April | 8% | 3% | 11% |
| May | 9% | 4% | 13% |
| June | 10% | 5% | 15% |
| July | 12% | 6% | 18% |
| August | 12% | 7% | 19% |
| September | 12% | 8% | 20% |
| October | 12% | 9% | 21% |
| November | 12% | 10% | 22% |
| December | 12% | 11% | 23% |
| January | 12% | 12%* | 24% |
*Interest continues at 1% per month until the taxes are fully paid. The county also notes that collection and attorney fees can begin in July for real property and may reach as high as 20% of the bill at collection.
Appointments and payment plans
You do not need an appointment to make a property tax payment. Cameron County says all tax office branch locations accept walk-in property tax payments, and online payment is also available.
Appointments are offered for the Brownsville Main Office and Southmost Tax Office through the county’s property tax appointment system. The county also warns that using the appointment system does not extend a filing or payment deadline.
For users who cannot pay a delinquent balance at once, Cameron County provides payment agreement options for eligible accounts. Delinquent tax agreements require the owner to be listed on the tax roll, include all delinquent accounts collected by Cameron County, and avoid recent default history on the same account.
- Use the property tax service appointments page if you want a scheduled visit instead of a walk-in payment.
- Review the county’s tax payment agreement information if your taxes are already delinquent.
- Bring or submit a valid government-issued ID and the required signed agreement form for delinquent tax arrangements.
For a standard delinquent payment schedule agreement, the down payment is 30% for a single year, or the greater of the current year amount or 30% of the total balance for multiple years. For certain homestead accounts with the required exemption, the county lists an installment agreement option with a minimum 30% down payment per account.
Values, exemptions, and address changes
The Cameron County Tax Office collects taxes, but property values, exemptions, ownership details, and billing address corrections are handled by the Cameron Appraisal District. That includes questions about appraised value, homestead exemptions, legal description errors, split-outs after a sale, and protest forms.
If your name or address is wrong on the statement, the appraisal district is the office that must correct it. The tax office says it can provide correction forms, but the actual determination belongs to the appraisal district.
You can review district forms and service options through the Cameron Appraisal District forms page. If you want tax rate hearing and taxing unit information tied to your property, the county also provides a Truth in Taxation property search with tax rate and hearing details.
Where to pay in person
Cameron County says taxpayers may visit any of its offices countywide for property tax matters. For full branch details, see the office locations and hours page.
Current year property taxes may also be paid at listed Lone Star National Bank locations in Cameron County if you present the consolidated tax bill for the year identified by the county.

Common questions
How do I look up a Cameron County property tax account online?
Use the Cameron County Tax Office search page and search by bill number, account number, owner name, mailing address, or property address. Start with the search option that matches the information you already have. After you find the account, review the bill details before paying or calling the office.
Do I need an appointment to pay property taxes in Cameron County?
No. Cameron County says appointments are not required for property tax payments, and branch locations are open for walk-in property tax payments. An appointment can still help if you want a scheduled visit at the offices that offer that option.
What if my property value, exemption, or mailing address is wrong?
Those issues go to the Cameron Appraisal District, not the tax office. Contact the appraisal district for value questions, exemption issues, legal description problems, or billing address corrections. If needed, use the district’s forms page to find the correct form before you call or visit.
Can I make payments on delinquent Cameron County property taxes?
Yes, the county lists payment agreement options for eligible delinquent accounts. You generally must include all delinquent accounts collected by Cameron County, provide the signed agreement form, and submit a valid government-issued ID. Review the agreement terms first so you know the required down payment before you go in.
What happens if I never received my tax bill?
The county says it is still the property owner’s responsibility to make sure the bill is received and paid on time. If you have not received a statement by mid-December, request another one or call for the amount due. You can also pay without the paper statement if you have your account number and the correct amount.
