Process steps
Follow the process from start to finish. Select a step to see who acts and what changes.
Asset book setup
Create financial and tax books with distinct basis, method, convention and rule version. Designate the financial posting book and preserve calculated forecasts separately from posted history.
Approval required
Tax election review
Review eligibility and applicable rule versions before applying elections to a tax book. Validate the effective tax year and acquisition/in-service facts; independently review the preparer’s proposal.
Depreciation calculation
Calculate one candidate per entity, book and period using versioned inputs. Do not update posted accumulated depreciation from draft calculations. Repeated requests reuse the same run identity.
Tax and audit reporting
Reconcile workpapers to the reviewed tax books and asset roll-forward. Export the retained version; record filing only with external acceptance evidence. Keep prior snapshots when a return or book is corrected.
