The challenge

A leading Australian transport energy provider had outgrown their manual, Excel-driven tax compliance process. With 50+ legal entities, the cracks were showing:

Fragmented processes: Tax effect accounting, income tax returns, and book-to-tax reconciliations ran as three disconnected workflows

Key person risk: Only one individual understood the Excel model's logic, creating bottlenecks and stress

Endless reconciliations: Book-to-tax true-up took 6–8 weeks of intensive manual work, with journals often booked 3+ months after lodgement

ATO pressure: Responding to Justified Trust queries required creating new workpapers from scratch, extending response times

Team burnout: Excessive hours during close, limited time for thorough reviews, mounting stress

Why they chose TaxTime

After evaluating three established market solutions, none were fit for purpose. TaxTime was selected for:

  • GL alignment: Tax treatment mapped directly to GL accounts with full transparency
  • One unified process: Provision to return on the same logic and data
  • Embedded governance: Approvals, version tracking, and audit trails built in
  • Entity-level precision: No more manual "pushdown" of group calculations
  • ATO-ready outputs: Complete PBT-to-taxable-income reconciliation on demand

The transformation

The income tax process was completely redesigned: from three fragmented workflows to one unified system.

Results

"The team no longer works excessive hours during close, resulting in a calmer, more controlled environment."

  • 91% faster book-to-tax reconciliation (6-8 weeks → 5 days)
  • One system, one process: provision and return on the same data
  • Eliminated key-person risk: logic is visible, anyone can review
  • ATO confidence secured: full lineage from disclosures to GL balances
  • Scalable foundation: now expanding to international jurisdictions

What's next

Encouraged by the transformation in Australia, the company is now extending TaxTime to international jurisdictions (Singapore, the US and New Zealand) to maintain a consolidated view of global tax positions with consistent standards across all entities.
