Cash accounting records income and expenses when money actually moves in or out of your bank account, while accrual accounting records them when they’re earned or incurred, regardless of when payment happens. Most small businesses can use the simpler cash method, but accrual gives a more accurate picture of performance, and some businesses are required to use it. The method you choose affects your profit and loss statement, your tax timing, and how you plan.
What Is Cash Basis Accounting?
Under the cash method, you record revenue when a customer pays you and an expense when you pay a bill. It’s simple, follows your bank balance closely, and is the default for many small service businesses.
What Is Accrual Basis Accounting?
Under the accrual method, you record revenue when you earn it, such as when you send an invoice, and an expense when you incur it, such as when you receive a vendor’s bill. Payment timing doesn’t matter. This matches income to the period in which the work happened.
How Do Cash and Accrual Differ in a Real Example?
Say you invoice a client $5,000 in December 2026, and they pay in January 2027.
| Cash Method | Accrual Method | |
|---|---|---|
| When the $5,000 is recorded | January 2027 | December 2026 |
| 2026 profit includes it? | No | Yes |
| Shows money owed to you? | No | Yes, as accounts receivable |
The work and the invoice are identical. Only the timing differs, which can change which tax year the income lands in.
What Are the Pros and Cons of Each Method?
| Cash | Accrual | |
|---|---|---|
| Simplicity | Easier | More complex |
| Reflects true performance | Less accurate | More accurate |
| Tracks unpaid invoices and bills | Not automatically | Yes |
| Tax timing flexibility | More | Less |
| Lenders and investors prefer | Sometimes | Often |
Which Method Should You Use?
Cash often fits small, service-based businesses with few unpaid invoices. Accrual often fits businesses with inventory, large receivables, or lenders who want detailed financials. Some businesses must use accrual if they exceed IRS gross receipts limits, so confirm your situation with a tax professional. Once you choose a method, you generally need IRS approval to switch, so decide carefully.
Why Does This Matter Before Year-End?
On the cash method, the timing of invoices and payments before December 31 can shift income and deductions between years. Reviewing this in Q4 gives you room to plan, and our small business tax deductions guide covers what to review. Both methods feed your profit and loss statement, and neither replaces watching cash flow, since profit and cash can differ under either method.
