The School Homestead Exemption Comes Off Taxable Value
The current Texas school homestead exemption is $140,000. It lowers the value used for school taxes; it is not a credit taken off the bill. Picture a qualifying home appraised at $300,000. The school-tax calculation starts from $160,000 before another school exemption or rule changes that number. A city, county, or special district may show a different taxable value because each makes its own exemption choices.
Apply through the Dallas Central Appraisal District, not the Dallas County Tax Office. DCAD sets the value and keeps the exemption record. Its chief appraiser rules on the application. Search for the property on DCAD's site, then open the homestead filing link from the account page. The general deadline is before May 1.
A buyer who takes ownership after January 1 should not assume the exemption has to wait a year. A partial-year exemption may be available if the former owner did not receive the same exemption for that tax year. The buyer still needs an ownership interest and must use the home as the main residence. DCAD can match that rule to the account.
