Sales and Use Tax Audit Services

The City of Houston, Texas is seeking a qualified vendor to provide sales and use tax audit services for businesses operating within its city limits. The agency needs to identify and correct tax misallocations, track business refund filings, and analyze locality tax collection data to project future revenues. Through this initiative, the agency aims to ensure tax compliance, protect its revenue base, and maintain accurate records of all businesses that have a tax nexus within the municipality. The scope of work requires the selected vendor to review the city's sales and use tax ordinances for included provisions, coverage, and classification definitions. The vendor must perform physical canvassing to verify the accuracy of businesses operating within the city limits and establish a structured liaison with the city coordinator to review progress at defined checkpoints. Additionally, the agency requires a tracking report that captures every occurrence of a business filing a refund, an amended return, a prepaid tax credit, a state audit, or an incorrect misallocation. Eligible bidders must be onshore organizations based entirely in the United States. The agency requires the performance of all audit work to take place offsite, and bidders must submit their proposals digitally via email or through the designated online portal. The agency has not disclosed a set budget and is looking for cost proposals within the submitted bids. The agency has scheduled a pre-proposal conference for June 29, 2026, to discuss the project requirements. Bidders must submit all clarification questions no later than July 10, 2026. The agency will evaluate proposals based on the submitted bids, though specific weighted evaluation criteria are not detailed in the initial solicitation.
