What's this GC into you for, with interest?
Prompt-pay interest (private work)
Tex. Prop. Code ch. 28Computed on the record
TX prompt-pay (private), 1999–present| Principal outstanding | $50,000.00 |
| Statutory interest, 167 days at 18% / yr since March 4, 2026 | $4,117.81 |
The lien clock runs beside this figure: TX lien and notice deadlines count down from your project dates. Subscribers track both clocks on every receivable.
Interest accrues from the day after payment is due (§28.004(a)) at 1.5% per month (§28.004(b)) and stops on delivery/mailing/judgment (§28.004(c)).
Good-faith dispute: the owner may withhold up to 100% of the disputed amount (110% residential) (§28.003).
Waiver of ch. 28 is void, with a limited single-family-residence exception (§28.006).
Does not apply to mineral/oilfield agreements (§28.010).
