What Is Cash Basis Accounting?

Under cash basis accounting, your books reflect only what has actually moved in or out of your bank account. Revenue is recorded when a customer pays; expenses are recorded when you write the check or the payment clears. This method is intuitive and closely tracks cash flow, making it easier to understand for business owners without accounting backgrounds. Cash basis accounting is generally available to sole proprietors, LLCs, and S-Corps with average annual gross receipts under $26 million (2024 threshold). One limitation: it can create a misleading picture of profitability — a business can look profitable in one month by delaying payments, or unprofitable in a month with large prepaid expenses. Cash basis accounting also makes it harder to identify trends in receivables and payables over time. For tax purposes, cash basis allows some timing flexibility in deferring income or accelerating deductions.

Cash basis accounting is fine for many small businesses, but switching to accrual becomes necessary as you scale, seek investment, or need more accurate profitability reporting. An accountant can help you decide when to switch, how to handle the conversion, and whether your current method is creating any tax or reporting blind spots.
