Appraisal District vs. Taxing Unit

"The appraisal district raised my taxes" mixes up two different organizations with two different jobs. Keeping the roles straight tells you where a problem belongs: a value dispute goes to the appraisal district and the ARB; a rate dispute belongs with the governing body that set the rate.

The appraisal district

The appraisal district, administered by a chief appraiser, determines the value of all taxable property in the county as of January 1, processes exemption and special-appraisal applications, and prepares the appraisal roll. It is governed by a board of directors. The appraisal district does not levy a property tax, does not set tax rates, and does not decide how much money local governments collect.

Taxing units

Taxing units — school districts, cities, counties, and special districts — set their own tax rates each year to raise the revenue their budgets require. Several types of taxing units can tax the same property. Many taxing units contract with the county's tax assessor-collector to collect their taxes; the assessor-collector then transfers the appropriate amounts to each unit. Taxpayers generally have until January 31 of the following year to pay before penalty and interest begin accruing on February 1.

The Appraisal Review Board (ARB)

The ARB is a board of local citizens that hears disagreements between property owners and the appraisal district about value and taxability. It is described in detail on our ARB page.

Who to contact for what

Worked example: the same bill, three different actors (illustrative)

Illustrative scenario with made-up numbers — actual amounts depend on your district and each unit's adopted rate.

  1. Scenario: your home is appraised at $450,000. Your tax bill lists four lines: county, city, school district, and community college.
  2. What the appraisal district did: set the $450,000 value once — the same value feeds every line, because all taxing units use the single appraised value from the appraisal roll.
  3. What the taxing units did: each adopted its own rate against that value. At (illustrative) rates of $0.40, $0.60, $1.00, and $0.10 per $100, the school line is $4,500 while the college line is $450 — different bodies, different budgets, same value.
  4. Why the split matters when you disagree: if you think $450,000 is too high, that is a value question for the appraisal district and ARB — protesting will not change any unit's rate. If you think the school rate is too high, that is decided by the school board's budget process, not by the protest.

What this tells you: value and rate are independent decisions made by different entities, and knowing which one you disagree with determines where your effort goes.

What it does not tell you: the actual rates adopted in your area, the payment deadlines your assessor-collector applies, or the effect exemptions have on each line.
