Client Testimonials

GTM has been an invaluable and agile partner to our company for years, especially amid complex global and domestic tax issues that require attention to detail amid tight deadlines. For instance, when we suddenly needed prompt State technical expertise last year, we contacted GTM for support. They mobilized resources quickly and worked seamlessly with our team to achieve a great outcome. Thanks to their expertise, the hope for a better outcome turned into a best-case scenario.

JJ Barios, VP Tax Trinseo

When I joined Avantax (f/k/a Blucora) I was hesitant having a tax provider that was not in the DFW area where my team and company was located. However, the commitment by GTM to understanding the business and accounting issues was extremely helpful and alleviated my concern. They were able to quickly gain my confidence, as well as our external auditor confidence. The level of service was tremendous. Throughout my time at Avantax, the company has been extremely active either with new accounting transactions or M&A activity. Our GTM team was a great partner in evaluating the tax impact of these transactions and any impact on our provision or compliance. I would highly recommend GTM as a service partner.

Stacy Murray, Chief Accounting Officer Advantax

The entire GTM team has been great to work with over the last year and a half. They are responsive to our changing needs and are quick to make suggestions for tax automation and continuously improve our processes!

Shannon McCall, Technical Accounting and SEC Reporting Expensify

Audit requests often come at the most inopportune times. GTM provided us the detailed research and support we needed to successfully advocate our position and reduce the assessment. I would recommend GTM to anyone needing audit support.

Eric Schultheis, Tax Director – Compliance Brenntag North America

Several years ago, we approached GTM as a provider of our fixed asset reporting. During procurement, we were impressed with how GTM was able to overcome our numerous fixed asset issues where other solutions fell short. Since then, GTM has been instrumental within our tax department, providing us fixed asset reporting for our U.S. consolidation. GTM continues to be extremely flexible with our ever-changing needs as a result of law changes. We know we can rely on GTM when deadlines are tight.

John Colucci, Senior Income Tax Analyst and Bonnie Baskin, CPA, Director – Income Tax

We approached GTM to help manage and support our tax team. The entire GTM team has been great to work with over the last several months. They jumped in and helped review and guide us when timelines were tight, and resources were lean. They are responsive and always helpful!
