TX HB1937

Changes documentation requirements for taxpayers from "contemporaneous" records to "sufficient" records when substantiating claims related to tax, penalty, or interest amounts in administrative or judicial proceedings

Abates the 10% penalty for unpaid tax determinations when a taxpayer timely files suit to dispute the amount; the penalty instead applies if the final judgment amount is not paid within 20 days

Creates a new process allowing persons who conduct managed audits under Sections 151.0231 or 201.3021 to bypass the redetermination process by filing a notice of intent within 60 days of receiving audit results, potentially proceeding directly to district court

Establishes procedures for suits disputing managed audit results, including automatic enjoinment of collection during litigation while allowing the comptroller to assert tax liens or require security such as cash deposits, surety bonds, or letters of credit

Applies to managed audits in progress and administrative or judicial proceedings pending or filed on or after the effective date, regardless of when the taxes at issue were due
