Case Study: AltaGas Service (US) achieves 25–40% faster tax provision and compliance with CSC Corptax Provision and Compliance

AltaGas - Customer Case Study

AltaGas faced the challenge of combining provision and compliance after acquiring a new gas company with two major subsidiaries, which left them consolidating tax processes across three companies with disparate systems. The fragmented environment forced manual work—merging Excel files for consolidated disclosures, extra hours to report by segment and utility vs non-utility, split teams in Michigan and Washington, D.C., and manual recalculation/dual true-ups and Excel journal entries that tied up the tax department for up to 30 days. AltaGas engaged CSC Corptax and its Provision and Compliance solution to address these issues.

CSC Corptax implemented its Provision and Compliance modules in under six months, giving AltaGas a single system to generate provisions and post directly to the general ledger so data is touched only once. The CSC Corptax solution enables detailed segment and utility reporting with industry-specific FERC accounting, eliminates Excel merges, and produces current taxes payable, current tax expense, accumulated deferred income taxes, and deferred tax expense within minutes of uploading monthly GL balances. AltaGas expects process time to shorten by at least 25%–40% as a result.
