We have worked with Mark Dunning and the TaxOps team for more than three years and couldn’t be happier with the relationship we’ve built. We initially chose TaxOps over other Big Four firms due to their R&D experience, responsiveness and attention to detail. The team works closely with our internal tax department to expeditiously and accurately complete R&D credit work in time for year-end provisions. TaxOps interviewers get in and get out quickly, minimizing disruptions at Ancestry. Additionally, our TaxOps team has had very little turnover, providing comfort and a friendly face to our engineers and IT professionals. TaxOps has also provided IRS controversy assistance with successful results. We are both fortunate and happy to have TaxOps working with us.”

Ed Gwynn, Vice President of Tax Ancestry
