Running a company in the United States means more than just incorporating it means staying compliant with accounting and tax laws that can differ by entity and state. Whether you’ve formed a Limited Liability Company (LLC) or a C-Corporation (C-Corp), accurate accounting is essential for growth, compliance, and investor confidence. LLC vs C-Corporation: Accounting Differences LLC Accounting: Income passes directly to members (owners) avoiding double taxation Simpler reporting: most LLCs file Form 1065 and issue K-1s to members. C-Corporation Accounting: Treated as a separate tax entity. Pays 21% federal corporate tax, then shareholders pay taxes on dividends. Files Form 1120 annually. Core Accounting Responsibilities 1. Bookkeeping: Maintain a clear record of income and expenses using tools like QuickBooks Online or Xero. 2. Bank Reconciliation: Match every transaction to your bank statements. 3. Sales Tax Compliance: Track and remit sales tax in states where you have nexus (physical or economic). 4. Financial Statements: Prepare Profit & Loss, Balance Sheet, and Cash Flow reports.
