A Texas sales tax audit may be triggered when a business:
- Exceeds the 500000 economic nexus threshold without registering
- Fails to obtain a Texas sales tax permit
- Files inconsistent or late returns
- Shows discrepancies between marketplace and reported sales
- Reports federal revenue that suggests Texas nexus
Remote sellers exceeding 500000 dollars in Texas revenue without a permit face increased enforcement risk.

Texas requires remote sellers to register once total Texas revenue exceeds 500000 dollars in the prior twelve month period. If this threshold is exceeded and no permit exists, enforcement risk increases.
Texas Economic Nexus Threshold
Failure to Register or File Returns
Audit risk increases when:
- A permit was never obtained
- Required returns were not filed
- Repeated late filings occur
Failure to file may leave prior periods open for review.
Marketplace and Revenue Discrepancies
The Texas Comptroller receives reporting from marketplace facilitators and payment processors. If marketplace reported revenue exceeds filed sales tax returns, the business may be reviewed.

Rapid Growth or Industry Outliers
Businesses experiencing rapid revenue growth or reporting significantly different revenue patterns compared to industry averages may face review. Federal filings may be compared to Texas sales tax reporting.
What Happens After an Audit Is Initiated
Once initiated, the Comptroller may:
- Request detailed financial records
- Review taxable and exempt sales
- Assess penalties and statutory interest
If nexus existed in prior periods, exposure may extend multiple years.
