Plum Creek one way, the San Marcos the other. Black waxy ground is not a sandy hill.
Caldwell County's seat is Lockhart. The Luling-Darst Creek fault splits the ground. A credit from one side is not automatically a credit from the other. The look is remote.
Lockhart sits on Byrd Lockhart's Plum Creek grant, and the Luling-Darst Creek fault runs from southwest to northeast under the work you invoice. Matthew Caldwell, a signer of the Texas Declaration of Independence, is the name the county file uses. Lawmakers had been asked for a Plum Creek County and chose this name instead. The county was formed in 1848 from Bastrop County and Gonzales County. U.S. Highway 183 and Farm Road 20 meet in Lockhart.
Northwest of the fault the ground is blackland, tall grass and mesquite on black waxy soil. Southeast the ground is hillier and sandy, with oak and elm. Plum Creek drains most of the interior inside the Guadalupe basin. The San Marcos River is the fence with Guadalupe County. Bastrop, Fayette, Gonzales, Guadalupe, Hays, and Travis touch the line.
Lockhart books can belong to two sides of one fault.
The July 2026 Comptroller figure used here shows a county sales tax of 0.5% for Caldwell County. State sales tax is 6.25%. Where a city has its own rate, that city rate stacks on the state rate and any county rate. The combined cap is 8.25%. City rates are not listed on this page.
Business personal property renditions go to the county appraisal district for Caldwell County. Put April 15 on the calendar. That district's form says which date controls the list.
The franchise report is due May 15. Texas has no state income tax. Neither date goes away because of that.
Split a Lockhart month by which side of the fault the job sat on. A shop ticket and a field ticket can both carry this county's name and still be two piles. The roads that meet in town only mark the courthouse. They do not merge the sides. The county rate is the same on both, so the rate will not do the split for you.
Book a time if both sides are one income line.
