Research and experimental expenditures are essential to many businesses, especially in technology, manufacturing, and healthcare. Taxpayers may use three alternative methods to account for these expenses before 2022. Firstly, they can deduct the costs in the year when they are paid or incurred. Secondly, they can treat the payments as deferred, amortizable for at least 60 months. Lastly, they can amortize the costs over ten years beginning in the tax year when they are paid or incurred. However, research and experimental expenditures paid or incurred after 2021 must be amortized ratably over five years. Although most states follow the federal treatment of these expenses, some conform only partially or have different regulations. It is crucial to understand the rules in each state to avoid costly errors when filing taxes.

IRCSec.174 Research and Experimental Expenditures

Federal Prior to 2022, a taxpayer may use one of three alternative methods to account for research and experimental expenditures: (1) currently deduct the expenditures in the year in which they are paid or incurred; (2) treat the expenditures as deferred expenses, amortizable over a period of at least 60 months beginning in the month that benefits are first realized from the expenditures; or (3) amortize the
expenditures over 10 years beginning in the tax year in which they are paid or incurred. Research or experimental expenditures that are neither treated as expenses nor deferred and amortized generally must be capitalized. Research and experimental expenditures paid or incurred in a tax year beginning after 2021 generally must be amortized ratably over five years. Any
amount paid or incurred in connection with the development of any software is treated as a research or experimental expenditure for purposes of this
amortization provision. A 15-year amortization period applies to research or experimental expenditures attributable to foreign research.
