When filing Schedule C for your business income, you must select an accounting method that clearly reflects income. The IRS allows three primary methods: (1) Cash, (2) Accrual, and (3) Other (specify). The method you choose must comply with the Internal Revenue Code and accurately reflect your business’s financial position.
Accounting Method Options
- Cash Method: Income is reported when it is actually or constructively received (for example, credited to your account or made available without restriction). Expenses are deducted when paid. Taxpayers that are not small business taxpayers generally must account for inventory using an accrual method; however, certain taxpayers may use alternative or hybrid methods if they clearly reflect income.
- Accrual Method: Income is reported when earned, and expenses are deducted when incurred, regardless of when cash is received or paid. This method is generally required for purchases and sales of inventory unless the taxpayer qualifies for the small business taxpayer exception or uses another permissible method.
- Other Methods: Any other method permitted by the Internal Revenue Code may be used, provided it clearly reflects income. This includes hybrid methods that combine elements of cash and accrual accounting.
Changing Your Accounting Method
To change your accounting method, you generally must file Form 3115. This includes changes such as switching from cash to accrual or vice versa, or changing inventory accounting methods. A change in accounting method may require a section 481(a) adjustment to prevent duplication or omission of income or expenses.
- Section 481(a) Adjustment: A section 481(a) adjustment is required when changing accounting methods to ensure that income or expenses are not duplicated or omitted. The adjustment reflects the cumulative difference between the old and new methods as of the beginning of the year of change. A net negative adjustment is generally deducted in the year of change, while a net positive adjustment is generally spread over four years. The adjustment is reported on Schedule C in a manner consistent with its nature.
- Inventory Changes: If changing your inventory accounting method, you must refigure the prior year’s closing inventory using the new method and enter the result on Line 35. If the amount differs from the prior year’s ending inventory, you must attach an explanation and include the difference as part of the section 481(a) adjustment.
Small Business Taxpayer Exception
Small business taxpayers may choose not to keep an inventory but must still use a method that clearly reflects income. If you choose not to keep an inventory, you may treat inventory as nonincidental materials and supplies or conf
orm to your financial accounting treatment. If you do keep an inventory, you must value it annually to determine cost of goods sold in Part III of Schedule C.
