78619 sits in San Marcos, Hays County. Properties here are appraised by Hays Central Appraisal District (Hays CAD), which is the same agency responsible for every parcel countywide. The protest deadline, filing methods, and ARB process are identical to elsewhere in Hays County — what's different is the underlying data.
Roughly 11% of 78619 homes were bumped 20%+ on this year's appraisal.
Even in a strong market, a 20%+ swing in one year is steep. If you got hit with one, the protest math is usually on your side.
The median residential parcel in 78619 is appraised at $972,680 for the 2026 tax year (from $946,980 in 2025). That's a median change of +0.1% year over year — but medians hide the tail.

The legal process is identical for every zip in Hays County — Texas Tax Code applies countywide and Hays CAD appraisers handle each protest the same way. What changes by zip is the underlying evidence:
Hays CAD mails Notices of Appraised Value (NOAVs) to property owners across 78619 and the rest of Hays County in mid-April. Your notice lists this year's appraised value and last year's, and the protest deadline is printed on it — Texas law sets it at May 15 or 30 days after the notice was mailed, whichever is later.
The protest math is simpler than it sounds: would your home actually sell for the appraised value today? Recent sales in 78619 are the strongest answer — they're also exactly the data Hays CAD appraisers use, so they engage on the merits when you bring better comps than they brought.
File online through the portal linked from https://hayscad.com, by mail to 21001 N. IH 35, Kyle, TX 78640, or in person at the same address. Online filing is fastest. Texas recognizes two independent grounds — market value and unequal appraisal — and which one (or both) actually applies depends on comparable-sales math and a statistical equity analysis against your peers. Our reports run both analyses on your specific property and tell you which grounds the data supports.
Successful protests are decided on three categories of evidence: recent comparable sales of similar homes in 78619, an unequal-appraisal analysis showing your value is higher than peers, and any condition documentation that explains why your home is worth less than the mass-appraisal model assumes. Many cases settle here without a formal hearing.
Hays CAD starts with an informal review where one of their appraisers offers a settlement based on your evidence. Accept it if it's fair. Reject it and your case advances to a formal Appraisal Review Board hearing — three private citizens who hear both sides for 5–7 minutes each and rule.
