Why Dentists Get Limited Benefit from the R&D Tax Credit Under the New Amortization Rules

by PracticeCFO | February 12, 2025

The Research and Development (R&D) tax credit has long been a valuable incentive for businesses investing in innovation. However, recent changes to tax law have significantly reduced its benefit for most dental practices. Specifically, under the new amortization rules introduced by the Tax Cuts and Jobs Act (TCJA) of 2017 (effective in 2022), expenses eligible for the R&D tax credit must now be amortized over five years instead of being deducted in full in the year incurred.

This creates a major trade-off for dentists. The same dollar spent that qualifies for an R&D credit can no longer be deducted immediately as a business expense. While the tax credit itself is often more valuable than a deduction, the amortization requirement means the benefit is spread over multiple years. Since a dollar of tax savings today is worth more than the same dollar in the future (due to the time value of money), this delay significantly reduces the practical benefit of claiming the credit.

Additionally, most dental practices do not engage in the level of technological or scientific experimentation required to qualify for the R&D tax credit. Even those that do may face heightened IRS scrutiny, as the agency frequently overturns claims from businesses that fail to meet the strict requirements. An audit could result in repaying the credit, plus penalties and interest.

Given these factors, we generally advise dentists against pursuing the R&D tax credit. The lost deduction, delayed benefit, and audit risk make it an unattractive option for most practices. Instead, we recommend focusing on other tax-saving strategies better suited to the dental industry’s financial landscape.
