Many CPAs likely come across clients who have historically mis- or over-capitalized expenditures, particularly in real estate, retail or manufacturing. Fortunately, tax preparers don’t need to amend years of returns to correct these issues. The IRS offers a fix for this with Form 3115 (Application for Change in Accounting Method) and it can be a game-changer for helping clients’ tax liability.

Many taxpayers mistakenly capitalize:

    • Building acquisition and improvement costs over longer recovery periods
    • Repair and maintenance costs that should have been expensed
    • Materials and supplies
    • Routine maintenance costs

The good news is that IRS allows CPAs and tax preparers to correct these issues and catch-up missed deductions on a client’s current year tax return.

What is Form 3115?

Form 3115 serves as a formal request to the IRS for permission to change how taxpayers report items of income and expenses for tax purposes.  The IRS has a listing of automatic method changes that can be used when completed Form 3115 in which the IRS does not require advance consent. The latest listing of designated automatic accounting method changes (DCN) can be found in Revenue Procedure 2024-23.
