Wyo. Dep’t of Revenue v. Qwest Corp.

After an audit, the Department of Revenue (DOR) determined that Qwest was not entitled to a refund of sales tax. The tax was incorrectly collected from Qwest's customers and remitted to the state because Qwest did not provide data showing the actual amount of tax collected and remitted by month and by country. Qwest subsequently produced to the DOR the actual sales tax information. The State Board of Equalization (SBOE) supplemented the record with the actual data and reversed the DOR's decision. The district court affirmed. At issue on appeal was whether the SBOE erred by considering the newly produced evidence. The Supreme Court (1)affirmed the SBOE's decision that Qwest was entitled to a refund, but concluded the SBOE erred by considering Qwest's evidence, which was not produced to the DOR during the audit; and (2) remanded so the refund amount could be calculated using an estimate procedure and information available during the audit.
