YEAR-ROUND PLANNING
Tax planning isn't a February conversation. S-election analysis, owner-comp structure, retirement-plan tax strategy, estimated-tax optimization: reviewed quarterly and at life events.
Year-roundPlanning · not just tax season
Send us your entity type, last year’s return, and current owner comp. Your Axiom tax preparer flags structural opportunities (S-election, QBI, retirement strategy) on the call.
A solo CPA spends February asking you for documents. Axiom’s tax team gets a closed trial balance + working papers on Feb 1 because the same team ran your bookkeeping the other eleven months. No information gaps. No back-and-forth. No data-request PDFs.
Quarterly estimates calculated from real YTD, not last year’s surprise. Entity-structure advice available year-round, not just at return time.
“Axiom delivered our first clean P&L by business day 5 of February. The previous CPA was sending us books in April. Because Axiom runs both the books and our VSHR payroll, journal entries post automatically and month-end is a non-event. The tax-prep handoff was seamless.”
Axiom bookkeeping hands off the closed trial balance to the tax-prep team on Feb 1. Zero re-keying. Zero information gaps. One team, two deliverables.
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.
