Sales Tax Audit Defense

With over 83% of sales and use tax audits resulting in assessments, the states visit early and often while the taxpayer becomes a never-ending revenue source. Upon engagement, TaxMatrix will defend the taxpayer against the audit, ensuring that proper audit methodology is employed to reduce the assessment, and identify and secure refunds along the way.

Our sales tax audit defense practice is managed by our client engagement team comprised of tax managers, former state auditors and tax attorneys well-versed in audit procedures. Our expert team always ensures your final assessment is fair and that any refunds due to you are identified and credited accordingly.

TaxMatrix can manage the audit process from start to finish or can simply serve as a final set of eyes. Our audit team will gather the files necessary to build the case and determine which issues are ideal for appeal. We manage the information flow between the client and the state taxing agency to ensure complete and accurate responses, while assisting with accelerated dispute resolution processes to reduce the costs associated with sales tax audit defense activities.


Our sales tax audit defense services include:

  •  Audit representation
  •  Audit coordination
  •  Audit sampling analysis and evaluation
  •  Taxability determinations
  •  2nd and final review (as a best practice)
  •  Audit appeals

We meet directly with auditors, dispute resolution officers, administrative hearing attorneys, and other agents to clearly identify all positions that impact our client’s ability to achieve a favorable outcome. We represent our clients’ interests to ensure they pay only their fair share of taxes.   

In addition, every client gains no-fee access to our Tax Help DeskSM for ongoing compliance support, saving you time and money when you need it most. (
