Texas may assess back sales tax for prior periods where a business had nexus but failed to file required returns. If returns were filed, the statute of limitations is generally limited. If returns were never filed or no permit was obtained, the assessment period may remain open. Unregistered sellers with nexus exposure may face review of multiple prior years.

When sales tax returns are filed, Texas generally has a limited period to assess additional tax.
The review period may extend if:

Filing does not eliminate audit risk but may limit how far back assessments can go.
