Case Study: GATX achieves 50% faster tax close and standardized, Excel-free tax reporting with insightsoftware Longview Tax

Longview Tax Out-of-the-Box Provision Solution Nets Quick Wins for Tax Reporting

GATX, a global company in the real estate, rental and leasing industry, faced mounting risk and inefficiency from an Excel-only tax process—multiple spreadsheets, manual formula checks, and auditor requests for tick-and-tie support—while also rolling out a new accounting system. To standardize reporting, eliminate Excel-based schedules and improve controls, GATX selected insightsoftware’s Longview Tax to replace spreadsheets and streamline the tax provision process.

insightsoftware implemented the out-of-the-box Longview Tax provision (including Return to Provision and Tax Basis Balance Sheet) and integrated it with GATX’s accounting ledger and Corptax compliance system. The deployment centralized tax data, improved transparency and internal controls, enabled flexible multidimensional reporting, and automated book-to-tax differences—helping GATX cut close timing by more than 50% in the first year while reducing risk from Excel-dependent processes.
