Texas current-year property taxes are commonly paid by January 31 when a bill was timely mailed.
General delinquency rule
Texas Comptroller says taxes imposed the previous year become delinquent on February 1 if a bill was mailed by January 10.
First penalty/interest hit
Cameron Tax Office says its posted delinquency notice adds 7% penalty and interest to unpaid property accounts.
| Situation | What to Know | Action |

How to estimate Cameron County property taxes
Use this for planning only. Your official bill depends on CAD taxable value, adopted rates, exemptions, special districts, city/school/MUD/drainage lines and whether your account has penalty or attorney fees.
Texas property tax formula
Example: If taxable value is $180,000 and the combined tax rate is $2.40 per $100, estimated tax is $180,000 ÷ 100 × $2.40 = $4,320, before penalties, exemptions, special fees or changes.
CAD gives values
Cameron CAD explains market value, net appraised value and taxable value. Taxable value is the amount used to calculate tax for each taxing unit.
Taxing units set rates
CAD says it does not set tax rates. Local governing bodies adopt rates and budgets.
Tax Office collects
The Tax Assessor-Collector collects taxes for many county, city, school and special districts.
Portal shows official due
Use the tax payment portal for real balance, payment history, penalties and original statement.
Cameron County Tax Office vs Cameron Appraisal District
This split is the most important thing to understand. The Tax Office cannot fix every value problem, and CAD does not process your payment.
| Question | Use This Office | Why |
|---|---|---|
| How much do I owe? | Cameron County Tax Office | Tax Office manages billing, payment history, receipts and collection. |
| Why did my value increase? | Cameron Appraisal District | CAD sets appraisal value and can explain market, net appraised and taxable value. |
| Where is my homestead exemption? | Cameron Appraisal District | CAD grants exemptions and updates ownership/address/value records. |
| Can I protest? | Cameron Appraisal District / ARB | Protests challenge market value or appraisal district actions. |
| Which rates are being proposed? | Truth in Taxation database | Shows taxing-unit rate and budget information that affects tax bills. |
| Why did my payment not post? | Cameron County Tax Office | Payment posting and receipt questions are collection-office matters. |
Cameron County property tax exemptions: what to check first
Exemptions can reduce taxable value, but they are handled by Cameron Appraisal District. The Tax Office bill only reflects what was placed on the appraisal roll.
Residence homestead
Check whether your homestead exemption is active on the CAD record. If missing, apply through Cameron CAD forms or portal.
Over-65 / disabled
These exemptions can affect tax amount and may support installment payment options when statutory conditions are met.
Disabled veteran
Veteran exemptions depend on disability rating, ownership and application proof. Confirm eligibility with CAD.
Non-profit / special exemptions
Cameron CAD FAQ notes some exemption types require annual application by April 30.
1
Search your CAD record first
Do not rely only on the tax bill.
▾
Open Cameron CAD Property Search. Search by PID, GEO ID, address or owner name. Review exemptions, net appraised value and taxable value.
2
Use official CAD forms or e-forms
Prepare ID and ownership proof before filing.
▾
Use Cameron CAD Forms or the Public Portal when available. Save submission proof and check the CAD record later.
3
Verify the tax bill updates
CAD changes may need to flow to the Tax Office.
▾
After CAD approves an exemption or correction, re-check both CAD and the Tax Office payment portal. If your lender pays escrow, send updated bill/correction details to your mortgage servicer.

1
Open Cameron CAD protest process
Read deadline and filing route first.
▾
Open Cameron CAD Protest Process. Choose online filing if possible because it gives immediate confirmation and portal evidence access.
2
Upload evidence before the hearing stage
Online portal evidence access matters.
▾
Use the online account to upload comments and documents, review CAD evidence and respond to settlement offers. CAD says all protesting owners can access CAD’s evidence packet through the online portal.
3
Do not skip formal ARB if settlement fails
Informal meeting and formal hearing are not the same.
▾
If you do not accept a settlement during the informal process, you get the opportunity to be heard by the Appraisal Review Board. Cameron CAD states no informal hearings are held the day of formal hearings.
Delinquent Cameron County property taxes: what to do next
Delinquent tax problems get more expensive as penalty, interest and collection costs increase. Search the live account first, then contact the Tax Office before the account moves deeper into collection.
Penalty and interest
Texas delinquent tax rules add penalty and interest after the delinquency date. Cameron posts current-year penalty information on the Tax Office website.
Payment agreement
The Cameron Tax Office site links to tax payment agreements. Ask directly before ignoring delinquent notices.
Real estate attorney fees
Cameron tax statement materials state delinquent real estate taxes may be turned over to a tax attorney on July 1 with attorney fees and collection costs added.
Over-65 / disabled deferral
If you are age 65 or older or disabled and the property is your residence homestead, contact CAD about possible postponement rights.
Cameron County Truth in Taxation and tax-rate research
Cameron property owners often see many taxing units on one consolidated statement: county, city, school district, drainage, water, navigation, MUD or college district lines.
Use Truth in Taxation
The county’s Truth in Taxation website explains how local budgets and adopted rates affect property tax bills.
Use CAD taxable value
Rate estimates require taxable value, not only market value.
Check each taxing unit
A Brownsville property may have different line items than a South Padre Island, Harlingen or rural property.
Tax Office collects for many units
The Tax Office may collect on behalf of cities, school districts and special districts, but those entities adopt their own rates.
