What is a C-Corporation tax return?

C-Corporations file Form 1120 (U.S. Corporation Income Tax Return) to report income, deductions, credits, and to calculate corporate income tax. :contentReference[oaicite:3]{index=3}

C-Corps are generally taxed at the corporate level, and shareholder dividends may be taxed again at the individual level (“double taxation”). Corporate tax is imposed under IRC §11 (commonly referenced as 21% for many corporations). :contentReference[oaicite:4]{index=4}

Documents we typically need

To prepare an accurate C-Corp return, we usually request:

• Profit & Loss statement and Balance Sheet (year-end)
• General ledger or bookkeeping export (QBO/Xero/other)
• Details for officer compensation and payroll summaries (if applicable)
• Fixed asset purchases/sales (vehicles, equipment, furniture)
• Loan/interest statements and major contracts
• Prior-year business tax return (for carryovers/consistency)

Common Form 1120 areas that cause IRS issues

• Unreconciled books (P&L doesn’t match Balance Sheet)
• Officer compensation not supported by payroll reporting
• Meals/auto/travel without adequate documentation
• Depreciation and asset disposals not tracked correctly
• Late/insufficient estimated payments (penalties/interest risk) :contentReference[oaicite:7]{index=7}
