Abstract: A service engine determines whether there is a potential lack of transaction tax compliance in a plurality of jurisdictions for a plurality of entities. The service engine generates and/or transmits tax compliance data which may include information about potential lack of tax compliance of an entity in various jurisdictions based on rules about establishing nexus for purposes of remitting transaction tax in the jurisdictions. The tax compliance data may include a notification about the generation of the information, such as a notification to the entity that there exists a potential lack of tax compliance of that entity in specific jurisdictions. The service engine may update the tax compliance data dynamically and send corresponding notifications, automatically in real time or near real time for the applicable entity as sales of the entity change and/or rules for establishing nexus change for various jurisdictions.
