This transaction set communicates tax rate information from a tax authority or rate administrator to affected parties. The sender notifies recipients of current or updated tax rates applicable to specific tax forms and jurisdictions. The BGN (Beginning Segment) establishes the context and purpose of the notification, while the mandatory TFS (Tax Form) segment identifies which tax forms the rates apply to. Within each tax form, the TRS (Tax Rate) segment specifies the actual rate details, optionally accompanied by AMT (Monetary Amount) and QTY (Quantity) segments to provide additional quantitative context. The N1 (Name) segment identifies the recipient organization, with optional address information provided through N3 (Address Information) and N4 (Geographic Location) segments.

For example, the State Tax Commission of Illinois sends a Tax Rate Notification to Acme Corporation, a multi-location retailer, indicating updated sales tax rates for the current fiscal year. The notification includes separate TFS segments for Form ST-1 (Sales Tax Return) and Form USE-1 (Use Tax Return), with corresponding TRS segments listing the new state rate of 6.25% and any applicable local add-on rates by county. For each rate, the notification includes QTY segments specifying the effective date and AMT segments clarifying any threshold amounts that trigger rate changes. Acme receives the transmission and updates its tax compliance system accordingly, ensuring that point-of-sale and accounting systems reflect the correct rates when calculating tax liability.
