How to File a Property Tax Protest Online in Texas (iFile / e-File, Step by Step)
Most Texas counties let you file your property tax protest online through the appraisal district's website — often called iFile, iSettle, or the Online Appeals portal — instead of mailing Form 50-132. You log in with the property ID and the unique iFile/online-protest code printed on your Notice of Appraised Value, select your grounds (market value and/or unequal appraisal), upload your evidence, and submit before the May 15 deadline. Many districts then make an online settlement offer you can accept or decline.
Online filing vs. paper Form 50-132
Every Texas protest is legally a Notice of Protest under Comptroller Form 50-132. Filing online does not change your rights or your grounds — it is simply a faster way to submit the same protest. When you file through an appraisal district's portal, the online form is the electronic equivalent of Form 50-132: it captures your owner and property information, the grounds you are protesting, and your requested value, then time-stamps the submission so you have proof you filed on time.
The trade-offs are practical. Online filing gives you an instant confirmation number, lets you upload evidence directly, and in many counties unlocks an online settlement offer (often branded iSettle) that can resolve your protest without a hearing. Paper filing still works everywhere the form is accepted, but you lose the instant confirmation and the online-settlement path, and you carry the risk of mail delay against your deadline. Not every county offers an online portal — smaller districts may only accept the paper Form 50-132 by mail, fax, or in person. See how to fill out Form 50-132 if you are filing on paper.
Before you start (what you need)
Have these in front of you before you open the portal:
Your Notice of Appraised Value. The appraisal district mails this each spring under Texas Tax Code §25.19. It carries three things you need to file online: your property ID / account number, the iFile or online-protest code (a unique per-property PIN printed on the notice), and the mailing date that sets your deadline.
Your grounds. Decide up front that you will protest on both market value (§41.41(a)(1)) and unequal appraisal (§41.43(b)(3)). More on this below.
Your evidence, as files. Have your comparable-property analysis, any sales or purchase data, photos, and repair estimates saved as PDFs or images ready to upload.
If you cannot find your iFile/online-protest code, contact your appraisal district — they can reissue it or verify your account. You cannot log in to most portals without both the property ID and the code from the notice.
Step-by-step: filing through the online portal
Open your county appraisal district's website
Go to the appraisal district (CAD) for the county where the property sits and look for a link labeled iFile, Online Protest, Online Appeals, or File a Protest. Portal names and layouts differ by county, but the function is the same. If you cannot find a protest link on the site, the county may not offer online filing (see the last section).
Log in with your property ID and iFile code
Enter the property ID / account number and the iFile / online-protest code exactly as printed on your Notice of Appraised Value. This pairing verifies you own the property and pulls up the correct account. Type the code carefully — a mistyped character is the most common reason a login fails.
Confirm the property and owner information
The portal displays the account it matched — check the address, owner name, and current appraised value. Correct any owner or mailing information the system lets you edit, and make sure you are filing on the right property before you continue.
Select your grounds — check BOTH
Choose the reasons you are protesting. Select "value is over market value" (§41.41(a)(1)) and "value is unequal compared with other properties" (§41.43(b)(3)). Checking both preserves every argument for your informal review and, if needed, your ARB hearing. See the next section for why this matters.
Enter your opinion of value
Most portals ask for your requested value — the number you believe is correct. Enter the value your evidence supports (for an unequal-appraisal case, the adjusted median of your comparables). If you are unsure, you can still file and refine your target with evidence; the important thing is to submit before the deadline.
Upload your evidence
Attach your comparable-property analysis, sales or purchase data, photos, and repair estimates as PDFs or images. Most portals accept several files. Upload your strongest evidence now rather than waiting — some counties use it to generate an online settlement offer immediately.
Review and submit before the deadline
Confirm your grounds, value, and attachments, then submit. The portal issues a confirmation number and usually an email receipt — save both as proof you filed on time. You are done unless the county returns a settlement offer.
Choosing your grounds (check BOTH market value and unequal appraisal)
The online form asks you to check boxes for your grounds, and this is the step people most often get wrong. Always select both:
Value is over market value — §41.41(a)(1)
This is the argument that the district set your value higher than what the property would actually sell for. It is supported by recent sales of similar homes, a recent purchase price or appraisal, and documented condition problems that lower value.
Value is unequal compared with other properties — §41.43(b)(3)
This is the unequal-appraisal ground: your property is appraised higher than the median appraised value of a reasonable number of comparable properties, appropriately adjusted for differences in size, age, and condition. It uses the district's own appraisal records as the yardstick, so it can win even in a rising market.
Checking both boxes on the online form costs you nothing and keeps every path open. If you only check one and later discover the other argument is stronger, you have narrowed your case for no reason. When in doubt, select both.
Uploading evidence
Online portals let you attach files directly to your protest — this is where the case is won or lost, not in the boxes you check. For an unequal-appraisal case, upload an analysis of 5–15 comparable properties pulled from your appraisal district's public records: square footage, effective year built, condition/quality grade, and appraised value, with each one's appraised value per square foot computed and adjusted, and the median identified. See how to find comparable properties. For a market-value case, upload recent sales of similar homes, a recent purchase price or appraisal, and photos or estimates for any condition problems.
Save everything as PDFs or clear images before you start, name the files plainly (for example, comparable-analysis.pdf), and keep the total organized so an appraiser can follow it in a minute. A clean, adjusted comparables packet gives the district a concrete number to reduce to.
Get the evidence packet you upload
TaxStand builds a hearing-ready evidence packet as a single PDF you upload straight to your county's online portal — comparable-property analysis for both grounds, across all 254 Texas counties. You file it, you keep 100% of the reduction.
Check my property →The online settlement offer (iSettle) — accept or go to hearing
After you file online, many appraisal districts respond with an online settlement offer — often branded iSettle or online settlement. The district reviews your account and evidence and proposes a reduced value you can accept or decline entirely online. Read the offer against your own target value from your comparables before you decide.
If you accept, the settlement is binding for the year and your protest is resolved — no hearing, no further steps. If you decline (or the county makes no offer), your protest continues on the normal track: an informal review one-on-one with an appraiser, where most protests settle, and then an Appraisal Review Board (ARB) hearing if you still disagree, where an independent panel issues a binding value. Know what happens at an ARB hearing before you decline a soft offer. Do not accept an offer that is above the value your evidence supports.
Deadlines & confirmation
Under Texas Tax Code §41.44, the deadline to file is May 15, or 30 days after the appraisal district mailed your Notice of Appraised Value — whichever date is later. Because the deadline keys off the mailing date printed on your notice, check that date; a late notice can extend your window past May 15. Filing online is time-stamped the moment you submit, which is one of its advantages over mail.
When you submit, save your confirmation number and any email receipt. That is your proof the protest was filed on time. If you filed close to the deadline and did not get a confirmation, contact the appraisal district immediately to verify receipt rather than assuming it went through.
If your county has no online portal
Not every Texas county offers online filing. Smaller appraisal districts may only accept the paper Form 50-132 by mail, fax, or in person. If you cannot find an iFile / Online Protest link on your CAD's website, or your notice does not include an online-protest code, plan to file on paper: complete Form 50-132, check both grounds, and deliver it to the appraisal district for the county where the property sits before your deadline — mailing early enough to beat the deadline, since paper is not time-stamped instantly. You can confirm your county's process and the current form at the authoritative source, the Texas Comptroller. For the full paper walkthrough, read how to protest property taxes yourself in Texas.
FAQ
How do I fill out the iFile protest form in Texas?
Log in to your county appraisal district's iFile portal with the property ID and the unique iFile/online-protest code printed on your Notice of Appraised Value, confirm the property and owner information, check both grounds (market value and unequal appraisal), enter your requested value, upload your evidence, and submit. The portal is the electronic equivalent of Form 50-132.
Where do I find my iFile / online-protest code?
It is printed on your Notice of Appraised Value, which the appraisal district mails each spring under Texas Tax Code §25.19. It is a unique per-property code you enter with your property ID to log in. If you cannot find it, contact your appraisal district to have it reissued.
Can I file my Texas property tax protest online?
Most Texas counties let you file online through the appraisal district's portal — often called iFile, iSettle, or Online Appeals. Some smaller counties only accept the paper Form 50-132 by mail, fax, or in person.
What is iSettle or an online settlement offer?
After you file online, many districts respond with an online settlement offer proposing a reduced value. If you accept it online, the settlement is binding for the year and no hearing is needed. If you decline, your protest proceeds to an informal review and then an ARB hearing.
Which grounds should I select on the online protest form?
Select both: "value is over market value" (§41.41(a)(1)) and "value is unequal compared with other properties" (§41.43(b)(3)). Checking both preserves every argument at your informal review and ARB hearing. It costs nothing to check both.
What is the deadline to e-file a property tax protest in Texas in 2026?
Under Texas Tax Code §41.44, the deadline is May 15, or 30 days after your Notice of Appraised Value was mailed, whichever is later. Online filing is time-stamped the moment you submit.
What evidence do I upload with an online protest?
Upload a comparable-property analysis (5–15 comps with square footage, year built, condition, and appraised value per square foot, adjusted, with the median identified) for an unequal-appraisal case, plus recent sales, a purchase price or appraisal, and condition photos for a market-value case. Save files as PDFs or images before you start.
What if my county does not have an online portal?
File the paper Form 50-132 by mail, fax, or in person with the appraisal district for the county where the property sits, before your deadline. Mail early, since paper is not time-stamped instantly.
