In this post, we’re delving into a topic that garners significant attention for a myriad of reasons: Form 3115 and the intricacies of accounting method changes. If you’ve ever explored the frequency with which this topic is searched, the results might surprise you.
A brief about my professional journey with Form 3115
I embarked on my career in 2012 with KPMG. Initially, I believed I was venturing into the realm of federal tax. However, I soon realized that while accounting methods do fall under tax, they present a distinct set of challenges. This led me to join the AMCs group. My initial roles were split evenly between compliance and methods and Credit Services. This experience was invaluable, introducing me to the complexities of Form 3115.
During this period, there was a significant shift in the regulatory landscape. Congress was introducing new laws concerning repair regulations. This posed a pivotal question for businesses, especially those with significant capital expenses like heavy equipment: Should maintenance costs be expensed or capitalized? This debate was particularly pronounced in Houston, a hub for oil and gas, where many businesses grappled with these capital expenditure decisions. Our office was at the forefront, pioneering the first repairs regulation study. The tool for these changes? Form 3115.

What is Form 3115 for?
At its core, Form 3115 is about altering accounting methods. These changes can be driven by various factors: regulatory shifts, strategic advantages, or rectifying past accounting errors. My experience in Houston highlighted the positive impact of these regulations. Many clients found themselves in a favorable position, able to deduct expenses more rapidly, leading to significant tax benefits.
Form 3115 generally requests the IRS’s consent to change an accounting method. An eligible automatic change obtains consent through compliance with the applicable filing procedure; a non-automatic change requires an IRS ruling. The Form 3115 instructions provide a useful starting point, but check the current List of Automatic Changes in Rev. Proc. 2025-23 and its subsequent modifications for the governing requirements.
What is an accounting method?
In essence, an accounting method dictates how transactions are recorded, encompassing both income and expenses. It’s the foundational framework that determines how businesses recognize and report their financial activities.
How is an accounting method established?
Proper treatment of an item on the first federal income tax return that reports it can establish an accounting method. Consistent treatment on two or more consecutively filed returns generally establishes a method even if the treatment is improper.
The one-year versus two-year distinction is a useful starting point, but it does not settle every case. A method can exist without that pattern, and special rules may apply. For example, certain depreciation corrections involving property placed in service in the preceding year can use Form 3115. Review the specific rule before choosing an amended return, an administrative adjustment request for a partnership, or Form 3115. Rev. Proc. 2015-13, §§2.01–2.03; Rev. Proc. 2025-23, §6.01(1)(b).
Examples of accounting methods
One primary example of an accounting method is income recognition via the cash or accrual method. These methods are particularly relevant for small businesses.
Our small-business inventory guide explains the eligibility, payment and recordkeeping conditions that determine whether merchandise purchases may be deducted before sale.
Our inventory-expensing case study shows why a current merchandise deduction and the cleanup of an old inventory balance require separate decisions.
It raises the question: Should income be reported to the IRS when received or when accrued? For many business owners, it’s logical to record income when received. However, in some scenarios, it’s more beneficial to record when accrued, especially considering the expense side. The decision hinges on whether expenses are recorded when cash is spent or when they are accrued. The best method often mirrors the business’s reality and minimizes adverse tax implications.
When do you need to change your accounting method?
The need to change an accounting method can arise from various reasons. Perhaps the current method is incorrect, or a more permissible method has been identified. Sometimes, regulatory changes, such as new laws passed by Congress, mandate a specific method. Form 3115 encompasses all these scenarios, from regulatory shifts to tax benefits and business growth considerations. For example, the section 448(c) small-business test generally uses average annual gross receipts for the preceding three taxable years. The inflation-adjusted limit is $31 million for tax years beginning in 2025 and $32 million for tax years beginning in 2026; an average equal to the limit qualifies. Aggregation and other special rules apply. Crossing the threshold can require accounting changes, depending on the business and the provision involved. Rev. Proc. 2024-40, §2.31; Rev. Proc. 2025-32, §4.30.
Navigating Form 3115
Automatic or Non-Automatic Changes
Start with the current IRS list of automatic changes and the applicable revenue procedure. Confirm that the proposed change is listed for the requested year and that the taxpayer meets its eligibility requirements. If an eligible automatic procedure applies, use it; otherwise, evaluate the non-automatic procedure. Rev. Proc. 2026-1, §9.01.
Finding Automatic Changes
When I’m trying to change a specific accounting method, I often use the CTRL+F function to search for keywords related to the desired method. For instance, if I’m working with a construction company aiming to alter their revenue accounting to the percentage of completion method, I’d search for “percentage of completion.” If this doesn’t yield results, I’d manually sift through the method changes. However, be prepared: there are hundreds of automatic accounting method changes. If you can’t pinpoint a specific change using this shortcut, finding the right method can be time-consuming.
When To File
For an automatic change, generally attach the original Form 3115 to the timely filed original federal income tax return, including extensions, for the year of change. File the required signed duplicate with the IRS no earlier than the first day of that year and no later than the date the return is actually filed. Check the current instructions for the submission address or available delivery method, and check the specific procedure for exceptions. Automatic changes have no user fee. Non-automatic requests generally must be filed during the requested year of change and require a user fee and IRS review. Rev. Proc. 2015-13, §6.03.
Additional Instructions
Often, the instructions will reference a “rev proc” for further details. This rev proc provides comprehensive information about eligibility and specific stipulations for the method change. If the method change you’re considering refers to a rev proc, it’s crucial to read and understand it. The automatic method change descriptions in the Form 3115 instructions are typically brief, spanning only a few sentences. For a thorough understanding, consulting the referenced rev proc is essential.
Selecting The Correct Change Number
Furthermore, while many parts on the Form 3115 might seem irrelevant, their relevance depends on the specific method change you’re pursuing. When you identify your method change, it will indicate which sections to complete, or the rev proc will provide this guidance. Key elements to focus on include the specific method you’re adopting and the automatic change number. Generally, each automatic change requires a separate Form 3115. Certain changes may or must be combined on one form when the applicable guidance expressly permits or requires it; include each required change number and the information for every change. Rev. Proc. 2015-13, §§6.02–6.03.
A common pitfall with Form 3115 is overlooking its intricate instructions or failing to select the appropriate automatic change number. Prior changes can affect eligibility for the automatic procedure. The general rules consider overall-method changes and changes involving the same item made or requested during the five taxable years ending with the proposed year of change. Specific exceptions and waivers apply, so this is not a blanket five-year ban on changing methods. Review the method history and the applicable procedure before choosing the filing route. Rev. Proc. 2015-13, §§5.01, 5.04–5.05.
Conclusion
Form 3115 is a pivotal tool for businesses navigating the complexities of accounting method changes. Whether driven by regulatory shifts, strategic advantages, or the need to rectify past accounting errors, understanding the intricacies of this form is crucial. With the ever-evolving landscape of tax regulations and the nuances of accounting methods, it’s essential to stay informed and seek expert guidance when needed.
