However, in January 2011, the IRS issued Revenue Procedure 2011-14 that provided an alternative accounting method. Rather than amending tax returns, architectural firms that have not previously taken the deduction may go back as far as 2006 and claim the deduction on their current year’s return using a Form 3115. A certification report and allocation letter must be filed with the Form 3115.
In most cases, claiming the §179D deduction on a Form 3115 is the preferred method. However, if a firm has already claimed the deduction on amended returns, their accounting method is established and should remain the same.
