Understanding Accounting Methods
An accounting method is the way a business records and reports its income and expenses for tax purposes. This can be Cash basis (Income and expenses are recorded when cash is received or paid, used generally by small businesses and Individuals); Accrual Basis (Income and expenses are recorded when they are earned or incurred, regardless of when cash is exchanged, used generally by larger businesses.); Hybrid (a combination of both). Once chosen, it should remain consistent unless a business requests approval to change it.
Method Change:
You might want to change your accounting method if: Your business has grown, and the existing method is no longer appropriate. You want to better match revenue with expenses. You’re considering tax advantages (some methods may allow you to defer taxes). You need to comply with IRS regulations or accounting rules (e.g., for inventory handling).
The taxpayer is required to calculate taxable income using both the previous accounting method and the new accounting method to identify any resulting differences, which must be reported as a Section 481(a) adjustment.
A voluntary change occurs when a taxpayer (business or individual) chooses to change their accounting method for better reporting. This is not a requirement but rather a decision made by the taxpayer. An involuntary change occurs when the IRS requires a taxpayer to change their accounting method. This typically happens because the taxpayer no longer qualifies for their current method or the IRS determines the current process is not in compliance with the law.
Overview Of Section 481(A) Adjustment
A Section 481(a) adjustment is a mechanism that addresses changes in accounting methods. The cumulative difference resulting from a change in accounting methods is referred to as the 481(a) adjustment, which is necessary to prevent the duplication or omission of amounts when taxable income (TI) is recalculated due to the method change. This adjustment may be either positive (favourable) or negative (unfavourable).
When Reporting A Section 481(A) Adjustment On Your Tax Return, You’ll Need To Follow These Steps:
1. Identify the Adjustment Amount
- First, calculate the difference between the income and expenses that would have been reported under the old accounting method and the new one.
- This difference is the Section 481(a) adjustment and will either increase or decrease your taxable income.
2. Identify the Adjustment Amount
- First, calculate the difference between the income and expenses that would have been reported under the old accounting method and the new one.
- This difference is the Section 481(a) adjustment and will either increase or decrease your taxable income.

Example Of A Section 481(A) Adjustment
A business had $10,000 of income earned in 2024 but not received until 2025. Under the cash basis, this income wouldn’t have been included in taxable income until 2025. However, under the accrual basis, this income must be included in taxable income in 2024, when it was earned.
The change in accounting method results in an additional $10,000 being recognized in 2024 under the accrual method, which would not have been included under the cash method. This $10,000 would be part of the Section 481(a) adjustment. Since this is a voluntary change to the accrual method, the $10,000 is considered a positive Section 481(a) adjustment, meaning it would be included in taxable income for the year of the change (2024).
For voluntary changes, a positive Section 481(a) adjustment (like in this case) is typically spread over four years. So, the business would include $2,500 of this $10,000 adjustment in taxable income each year for the next four years (2024, 2025, 2026, and 2027).
Conclusion
To report a Section 481(a) adjustment, use Form 3115 and make the appropriate adjustments to your taxable income as described in your tax return.
