vamseeachanta Cash-Basis Corporate Tax Reconciliation
When preparing Form 1120 for a cash-method C-Corp with conflicting revenue records (invoices vs. bank deposits), establish the expense/bank-activity sheet as the source of truth—it reflects actual cash receipts, not invoice dates. Map every line of the authoritative expense sheet directly to Form 1120 and Schedule L line items. For entities without prior-year returns, reconstruct beginning-of-year balances from known liabilities (e.g., outstanding loan principal) and work backward to validate the equity position. This approach resolves revenue timing disputes and ensures Schedule M-1 reconciliation aligns with cash-basis accounting rules.
