02
Books Review
Trial balance reconciled to bank statements; any adjustments proposed and approved before filing.
03
Return Prep
Federal and state returns prepared with full workpapers, M-1/M-3 reconciliation, and K-1s (if applicable).

Filing & Planning
E-file federal and MA, deliver K-1s, and schedule the Q1 estimated-tax planning call for the next year.
Transparent flat-fee or hourly pricing.
Business returns start at $750 for straightforward partnership filings and scale with complexity, multi-state nexus, or the condition of the books. See the full public fee schedule for detailed breakdowns and Circular 230 §10.27 compliance notes.
