# Form 1120 Preparation from Expense Sheet When a client provides an expense sheet as source-of-truth for a C-Corp cash-basis filing but lacks prior-year returns or complete bank records: (1) validate revenue/expense totals against the expense sheet, (2) map each expense line to the appropriate Form 1120 schedule (COGS, compensation, deductions, etc.), (3) build Schedule L balance sheet by reconstructing BOY balances from known entity facts (incorporation date, loan amounts, retained earnings assumptions), (4) identify critical gaps (bank balances on 1/1 and 12/31, capital stock, prior retained earnings, estimated tax payments) and request them explicitly, (5) confirm filing tool supports Form 1120 (FreeTaxUSA does not).
