Protecting Your Innovation Incentives
The IRS and state revenue departments frequently scrutinize R&D tax credit claims due to their complex nature and high financial value. Even a perfectly legitimate claim can be severely reduced or fully denied if it is not defended properly during an examination. Swanson Reed provides an aggressive, methodical defense.
1. Controlling Information Document Requests (IDRs)
When an audit begins, the IRS issues IDRs to request specific documentation. Improperly answering these requests—either by providing too little information or over-sharing unrelated data—can dramatically expand the scope of the audit. Our experts meticulously draft and review all IDR responses. We ensure that the IRS receives exactly what is legally required to satisfy their inquiry, utilizing targeted technical reports, nexus matrices, and contemporaneous documentation, without exposing your company to unwarranted scrutiny.
2. Defending the Four-Part Test
Examiners often challenge whether specific projects truly meet the statutory definition of R&D. Our specialized engineers work directly with your technical teams to translate complex scientific and developmental processes into the tax language required by the IRS. We provide compelling, evidence-based presentations that unequivocally demonstrate how your activities pass the Section 41 four-part test: technological in nature, permitted purpose, elimination of uncertainty, and process of experimentation.
3. Financial Substantiation and Appeals
Beyond the technical activities, auditors will scrutinize your financial calculations—specifically how W-2 wages, supplies, and contractor costs were allocated to qualified projects. We provide robust defense of your base period calculations and QRE tracing. If a tax examiner issues a Notice of Proposed Adjustment (NOPA) that we believe is incorrect, Swanson Reed is fully equipped to escalate your case, representing you through the IRS Appeals process to secure a fair and favorable resolution.
