Streamline tax management with our sales & use tax audit services

With thousands of global tax jurisdictions (US Sales & Use Tax, VAT, GST), it is not a question of did you overpay sales and use tax, but how much did you overpay. And a 2018 US Supreme Court ruling that every online order is subject to tax has thrown gasoline on the fire. Every US supplier will now charge you tax and you have no idea if they are charging it correctly.

Tax professionals from APEX Analytix can help. We have been protecting the largest companies in the world from overpayments in AP for the past 30 years and we have developed software to identify every tax overpayment. This includes the identification of overpayments, outreach to suppliers and local or state agencies, and putting that money back in your account.

Producing Impactful Results. APEX Analytix tax professionals found that the US operations of a Global 2000 company repeatedly paid both sales and use taxes on the same purchase transactions. We filed a successful refund claim for approximately $3 million in overpaid taxes.

Benefit from expertise and technology to help you identify and recover overpayments.

Two distinct advantages set APEX Analytix apart from other global tax services providers. First, we’ve built our own team of highly experienced professionals. That stands us in stark contrast to the many providers who rely on armies of temp workers or junior personnel to conduct tax reviews.

Second, our team is armed with APEX Analytix FirstStrike®, a software program that can quickly analyze large volumes of data from disparate payment systems and platforms. We simply find more and recover more in less time. We offer the same technology as licensed software – allowing you to continuously monitor disbursements and protect against future tax overpayments.

This winning combination of experience and technology-enabled analysis means better-informed advice and air-tight claims.
