Form 3115

Form 3115, Application for Change in Accounting Method, is how a taxpayer gets permission to change the way it computes taxable income for an item. The default rule is that a method, once adopted, cannot be changed without the consent of the Commissioner, and that consent is obtained through this form. Correcting an error is not a method change and does not go here; changing a method that has been used consistently, even if it was wrong, generally does.

The threshold question is whether the change is automatic. The automatic consent procedures cover a long, frequently revised list of changes, and for those the form is filed with the timely filed return for the year of change, with a duplicate copy sent to the IRS service center. There is no user fee and consent is granted by following the procedure. Non-automatic changes require advance consent: the form goes in during the year of change, a user fee applies, and the IRS may or may not grant it. Filing an automatic change under the non-automatic procedure, or missing the duplicate copy, are the two mechanical failures that cost the change.

The Section 481(a) adjustment is the substance of the form. It quantifies the cumulative difference between the old method and the new one as of the beginning of the year of change, so that no item of income or deduction is duplicated or omitted in the transition. The sign determines the timing: a negative adjustment, which decreases taxable income, is taken entirely in the year of change, while a positive adjustment is spread ratably over four years. A de minimis election allows a small positive adjustment to be taken in one year. Because the computation reaches back over the entire life of the item, it is usually the most time-consuming part of the engagement and the part with the least available documentation.

The reason to bother is audit protection. A properly filed change generally bars the IRS from raising the prior treatment of that item in earlier years, which converts an open exposure into a scheduled adjustment. That trade is why method changes are often the cleanest way to fix a long-running treatment issue: the taxpayer pays the cumulative catch-up on its own terms rather than defending the history.

Common changes preparers see repeatedly: depreciation method or recovery period corrections after a cost segregation study, changes in the treatment of prepaid expenses, moving between the cash and accrual methods when the gross receipts test is crossed, inventory and UNICAP method changes, and revenue recognition changes following an accounting standards adoption. Research and experimental expenditures under Section 174 have had their own transition procedures, sometimes permitting a statement in lieu of the form.
