Sales Tax Audit & Refund Services

Beginning with an audit assessment, we help our clients identify overpayments and secure sales tax refunds. As part of an audit/refund engagement, we also recommend and implement cost-saving process improvements and provide ongoing support to help clients reduce overall internal costs long-term.

Sales Tax Systems & Automation

Using a combination of automation experience and sales tax expertise, GTM provides sales tax system design, implementation, upgrades, customizations, and maintenance. As a value-add, we perform system check-ups, recommend process improvements, and are available for ongoing help desk support.

Property Tax

Many companies may not recognize property tax as a controllable cost that impacts the bottom line. If not addressed properly, this can often lead to missed savings opportunities, including allowable deductions and exemptions. GTM provides property tax outsourcing and advisory services to ensure that companies are filing correctly and taking advantage of allowable savings opportunities. Our services include property tax compliance, valuation review and appeals, audit support, and fixed asset and reclassification reviews. Read More
