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:

  • Ledger 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, US, and New Zealand — to maintain a consolidated view of global tax positions with consistent standards across all entities.
