The short answer
If your rental's assessed value looks too high, most states let you challenge it through a local appeal. Deadlines are short and set by state and local law, so check your notice as soon as it arrives. Strong appeals rest on evidence of market value, such as comparable sales or the property's income.

How assessment appeals generally work
A local assessor or appraisal district values your property, and your tax bill applies local rates to that value. An appeal usually challenges the value or how the property is listed, not the tax rate. The usual path looks like this:
- You receive a notice of value or an assessment.
- You may ask for an informal review with the assessor or appraisal district.
- You file a formal appeal with a local board by the deadline.
- The board holds a hearing and decides.
- You may take the decision further, often to court.
Names, forms and deadlines differ by state and county. The two examples below show how much they vary.
Deadlines are set locally
In Texas, an owner generally must file a written notice of protest with the appraisal review board by May 15 or the 30th day after the notice of appraised value was delivered, whichever is later (Tex. Tax Code § 41.44).
In California, an application for a reduction is filed with the county board between July 2 and September 15. The last day is extended to November 30 in a county where the assessor does not send value notices to all real property owners on the secured roll by August 1 (Cal. Rev. & Tax. Code § 1603).
Put the deadline on your calendar the day the notice arrives. A strong case filed late is usually not heard.
Example: Texas protests
Texas protests go to the county's appraisal review board (ARB). Owners can protest the appraised value and unequal appraisal of their property, among other actions (Tex. Tax Code § 41.41). The Texas Comptroller explains that you can request an informal conference with the appraisal district before the formal hearing, and that you can request copies of the information the district will use at the hearing.
In a protest of value or unequal appraisal, the appraisal district generally has the burden of establishing the value by a preponderance of the evidence (Tex. Tax Code § 41.43). After the ARB decides, the Comptroller describes further options: a petition in state district court within 60 days of receiving the order, regular binding arbitration for eligible properties, or an appeal to the State Office of Administrative Hearings for higher-value properties. A court appeal generally requires paying the undisputed part of the taxes before the delinquency date.
Example: California assessment appeals
In California, the county board of supervisors, or an assessment appeals board it creates, sits as the county board of equalization. You file the State Board of Equalization's form BOE-305-AH with the clerk of the board. The application must be verified and must show the facts behind the requested reduction and your opinion of the property's full value (Cal. Rev. & Tax. Code § 1603).
The State Board of Equalization explains that a hearing and final decision generally must happen within two years of a timely application, unless both sides agree to extend. The board's decision cannot be reheard, but either side may go to superior court.
Evidence that persuades
Bring evidence of market value, not complaints about the tax bill. The Texas Comptroller lists items such as photographs of your property and comparable properties, sales price documentation, and repair receipts or estimates.
For a rental, the income approach can matter. Texas law requires the chief appraiser to consider the cost, income and market data comparison methods and use the most appropriate one (Tex. Tax Code § 23.0101). When the income method is used, the appraiser analyzes comparable rental data, operating expenses and capitalization rates (Tex. Tax Code § 23.012). Actual rents, vacancy and operating costs for your property can support your case.
In Texas, for a property valued at $1 million or less, delivering a qualifying certified appraisal to the chief appraiser at least 14 days before the hearing raises the district's burden to clear and convincing evidence (Tex. Tax Code § 41.43(a-1)).
Steps to prepare
- Read the notice and confirm the deadline for your county.
- Check the property record for errors in size, bedrooms, bathrooms or condition.
- Gather recent sales of similar nearby properties.
- Prepare a 12-month summary of rent, vacancy and operating expenses.
- Add photos and repair estimates for any condition problems.
- File on time, attend any informal review and keep copies of everything.
After the decision
Record the final value and next year's deadline. Property taxes you pay on a rental are reported on the taxes line of Schedule E, so keep the bills and payment records with your tax files. If you plan to go to court, the Texas Comptroller recommends talking with an attorney before you file a petition.

Common questions
When is the deadline to appeal my property assessment?
It depends on your state and county. In Texas it is generally May 15 or 30 days after the notice was delivered, whichever is later. In California the regular period is July 2 to September 15, or November 30 in some counties.
What evidence works best for a rental?
Recent sales of comparable properties, photos and repair estimates for condition problems, and your actual rent, vacancy and operating expenses if the income approach is relevant.
Do I still pay my taxes while I appeal?
Rules vary. In Texas, appealing to district court requires paying the undisputed part of the taxes before the delinquency date. Check your county's rules so you avoid penalties.
Do I need a lawyer to appeal?
Not usually for an informal review or a board hearing. The Texas Comptroller recommends talking with an attorney before filing a petition in district court.
