Because Axiom keeps your books year-round, the tax team starts with a closed trial balance and working papers on February 1, reducing document requests and back-and-forth.
Quarterly estimates use current year-to-date numbers, and entity-structure advice is available year-round.
Axiom bookkeeping hands off the closed trial balance to the tax-prep team on Feb 1. The same team does both, so nothing is entered twice.
Closed trial balance + adjusting entries + working papers handed off Feb 1 with year-end reconciliations complete.
K-1s flow into owner personal returns. Pass-through income + retirement contributions + QBI coordinated across entity and owner.
Book-tax differences (depreciation, accrual adjustments) documented and re-applied in next year's books as needed.
