Surplus Lines Stamping Office of Texas (SLTX)
Definition
The Surplus Lines Stamping Office of Texas (SLTX) is the organization that records and reviews surplus lines policies placed in Texas. Surplus lines agents file their policies with it, and it helps the state track the market and the taxes and stamping fees owed.
In Plain English
When your agent places a policy with a non-admitted insurer, the surplus lines agent must file it with SLTX. The office reviews filings for compliance, keeps a list of eligible surplus lines insurers and supports the collection of the stamping fee.
You rarely deal with SLTX directly. Its main effect on you is the small stamping fee, listed next to the surplus lines tax on your premium invoice and the added layer of review on your policy.
SLTX does not approve rates or guarantee claims. For complaints about an insurer or agent, the Texas Department of Insurance is the regulator.

Why It Matters for Texas Property Owners
SLTX exists specifically for the Texas surplus lines market, which is a major source of coverage for coastal, older and hard-to-place commercial property in the state.
What to Watch For
- Look for the stamping fee as a separate line on surplus lines quotes and invoices.
- Ask your agent to confirm the insurer is on the Texas eligible surplus lines list.
- Use TDI, not SLTX, for complaints about a claim or an agent.
