Case Study: HOCHTIEF improves tax compliance with Alessa by Tier1 Financial Solutions

Using Alessa for Tax Compliance

HOCHTIEF, one of Germany’s largest construction companies with global operations, needed to modernize its tax compliance processes. After moving to SAP and other digital tools, the company still relied on manual Excel-based work, printed forms, and separate software for tax calculations because its existing tax system could not support electronic tax filing or keep up with growing transaction volumes and changing regulations. Vendor Alessa, by Tier1 Financial Solutions, was brought in to help address these challenges.

Working with Audicon GmbH, HOCHTIEF implemented Alessa to automate tax compliance by extracting data from SAP and running a wide set of controls for VAT, invoices, expenses, sanctions, and fraud indicators, with exceptions routed through workflows for review. The solution also provided dashboards to track alerts by status and risk level, helping HOCHTIEF monitor compliance performance and ensure resolution of issues. With Alessa, HOCHTIEF strengthened compliance with complex tax regulations, reduced the risk of fines and reputational damage, and achieved these benefits without adding dedicated compliance staff.
