Background
The Internal Revenue Service (IRS) is seeking to procure Sales Tax Tables and Sales Tax Deduction Calculator services for the Tax Year 2025. This initiative aims to develop necessary data for the Policy and Program Impact Lab to create general sales tax tables and update the sales tax deduction calculator available on IRS.gov. The requirement arises from U.S. tax law, which mandates the publication of State and Local general sales tax tables for taxpayers eligible to deduct these taxes.

The IRS intends to utilize State and Local sales tax data for the 2026 filing season, building on previous contracts awarded for similar services.

Work Details
The contractor will be responsible for several key tasks:
1. Conduct a kickoff meeting within 10 business days post-award to discuss contractual tasks, deliverables, and timelines with IRS stakeholders.
2. Provide State general sales tax rates for 2025 in an Excel spreadsheet named '2025 State Rates', including state abbreviations, names, rates, effective dates, and details on any changes in rates during the year.
3. Deliver two spreadsheets named '2025 state taxability' and '2025 local taxability' containing data on spending categories identified by the IRS, indicating whether each category is taxable or not as of July 1, 2025. These spreadsheets must include Universal Classification Codes (UCC) and be organized into tabs for existing databases and unique sources.
4. Provide local general sales tax rates for each unique ZIP Code/County/City combination in the U.S., covering January 1 through December 31, 2025, in both CSV and vertical bar delimited formats under the file name '2025 STDC'. Additionally, a separate file named '2025 STDC military' will be required for overseas U.S. military zones. All data files must adhere to specified formats and include detailed records without duplicates.

Period of Performance
The contract period is from September 1, 2025, to December 31, 2026, with specific deliverable deadlines set throughout this timeframe.

Place of Performance
The contract will be performed at the contractor's facility.
