10 Tips To Find The Best R&D Tax Credit Consultants

Many eligible businesses overlook R&D tax credits, believing they’re reserved for large corporations or white-coat projects. In doing so, they miss out on hundreds of thousands of dollars in potential savings. Any company in any sector may qualify for tax relief, but the process requires careful scrutiny.

How do you pick an advisor who maximises your claim and ensures compliance?

1. Look for Technical and Tax Expertise

The best consultants do more than just master the tax code — they understand your company’s technical efforts, too. Choose a firm with Certified Public Accountants (CPAs) and other professionals who are knowledgeable about your work. 

This dual perspective guarantees your activities are evaluated correctly under IRS guidelines, particularly the four-part test — qualified purpose, elimination of uncertainty, process of experimentation and technological in nature. This expertise means no eligible expense is left unclaimed and you’re less likely to have your credits reduced or denied. 

2. Evaluate Their Audit Defence Experience

Any specialist can apply for reductions, but defending those claims requires additional expertise. Ask how often their studies have been audited, what the outcomes were and who represents clients if challenged. A firm with an in-house defense team and a strong compliance success rate signals credibility and technical rigor.

3. Ask About Their Approach to Section 174 Compliance

The rules under IRC Section 174 have undergone several changes in recent years, particularly between 2022 and 2024. An experienced consultant should clearly explain how these amendments affect your company’s specific situation, including how to handle transitional years and how the code interacts with your R&D tax credit calculations. They should also provide documentation and election strategies that keep you compliant, should the IRS issue new guidance or reverse course again.

Be cautious of advisors who downplay this complexity as Section 174 planning remains a moving target.

4. Request for Transparent Methodology and Documentation

A credible advisor should keep records of everything, including project descriptions, wage allocations, experimentation evidence and cost tracing, in a way that withstands the highest level of scrutiny. Request to see a sample study or documentation framework. If their process is detailed and customised to your project, that’s a green flag.

5. Prioritise Industry Familiarity Over Generic Experience

Tax relief applies differently across sectors. Software development, manufacturing, construction and biotech all have unique qualifying activities. Experts benchmark your work against industry norms and can identify less obvious initiatives that otherwise go unnoticed, such as process improvements or prototype testing.

6. Understand Their Risk and Fee Structure

Ask what kind of pricing they use and see which fits your comfort level with risk. Remember, it costs money to get money. Contingent fees may seem appealing, but they can sometimes encourage inflated claims, which could increase audit risk.

Fixed fees, on the other hand, tend to support more careful, compliance-driven work. Larger businesses should look for firms that can collaborate with their CPA or finance team for stronger oversight and smoother integration.

7. Review How They Work With Your CPA or Tax Team

Top-tier consultants partner with your in-house CPA, not compete with them. They coordinate data requests, verify accounting accuracy and ensure the resulting study ties well into your return. Ask how they communicate and whether they’ll support your CPA during an examination or filing review.

8. Assess Their Technical Interview Process

The most accurate claims come from firsthand conversations instead of generated questionnaires. Your advisor should meet directly with in-house professionals to find which of your projects qualify. This step distinguishes high-quality studies that reflect the nuances of your efforts from cookie-cutter reports.

9. Check References and Independent Reviews

Before signing, request client references from businesses that are similar in size and industry to yours and see their success rates. You should also review independent testimonials or case studies that show real results like credits earned, audits passed or taxes saved.

10. Verify Their Understanding of Current IRS Trends

IRS scrutiny continues to increase, especially for amended returns and software claims. Confirm that your consultant keeps up with the ever-evolving rules, emerging court cases and new laws and that they apply that knowledge to your application each year.
