No Stone Unturned.™
Since our inception in 2002, ThreeFive was built on the guiding principles that we eliminate risk to our clients by performing Services on a contingent basis. Our core State and Federal services include state audit defense, sales and use tax refunds, utility audits, research and development credits, cost segregation, fixed asset reviews, meals and entertainment, and the Sec 179D tax deduction or EECBD (Energy Efficient Commercial Building Deduction.)
No matter how recent or how thorough your last audit or study was, there’s a good chance you’re leaving money on the table.
At ThreeFive, our pledge is to provide you with excellent service while recovering the full amount due your corporation or legal entity. Each ThreeFive professional is selected based on their integrity, ability to provide outstanding service, and expertise in the subject matter being reviewed. This includes but is not limited to manufacturing, accounting, state and local tax laws, forensic discovery, and engineering.
We have a presence in and have performed tax benefit studies for these states.

All Services are performed by a diverse cadre of seasoned tax professionals each with decades of State DOR or IRS tax, data, and field audit experience. Our core services include multi-state sales and use tax refunds and Federal tax credits and deductions obtained to lower taxable income for corporations. We don’t get paid unless you receive a tax benefit as a result of our work. The largest accounting and consulting firms typically underperform in this area – we simply do it better, and almost always find significant refunds, credits, or deductions left on the table. We always include audit defense, if needed, and our comprehensive approach ensures you realize all available tax benefits.
ThreeFive's data security platform is designed to operate entirely within your own SOC 2–compliant environment using dedicated virtual machines to isolate and process sensitive information.
By deploying our services directly inside your controlled perimeter, we inherit your existing security controls — encryption at rest and in transit, role-based access, logging, and continuous monitoring — so that your data never leaves your trusted infrastructure. This approach ensures airtight separation between workloads, minimizes the attack surface, and gives you full visibility and governance over all operations handling sensitive information.
We treat and respect each client the same, whether providing a new service or taking a second pass at another firm's work. We get results for our clients, from larger Fortune 500 corporations that have become repeat customers to startups engaging us to obtain R&D credits.

ThreeFive utilizes a deep bench of tax professionals including former IRS and DOR auditors, lawyers, statisticians, CPAs, and data & inventory specialists.
Most have spent decades within their profession or a taxing authority honing their expertise, ensuring the highest level of service to clients until the full amount of a refund, credit or deduction is realized by our clients.
