Should I hire a CPA or a tax attorney to handle a sales tax audit?

TL;DR

A SALT-experienced CPA or sales tax consultant handles most audits effectively and costs far less than an attorney. Bring in a tax attorney when fraud allegations, criminal exposure, or litigation enter the picture. The critical qualifier in both cases is SALT specialization — a general CPA or generalist attorney is not a substitute.

For most audits, a SALT-experienced CPA or sales tax consultant is the right call. Bring in a tax attorney when fraud or litigation enters the picture.

Key takeaways

  • Most audits: CPA or sales tax consultant with SALT experience: they understand the audit process, can represent you with the state DOR, and handle the administrative resolution without attorney-level costs
  • Tax attorney: necessary when: the audit involves fraud allegations, criminal referral risk, litigation before a state tax court or administrative tribunal, or you need attorney-client privilege to protect internal communications during the process
  • The most important qualification is SALT specialization: a generalist CPA or attorney who “handles taxes” is not the same as a SALT practitioner; audit dynamics, negotiation leverage, and state-specific knowledge matter significantly
  • Enrolled Agents (EAs): some EAs specialize in state tax; they’re licensed to represent taxpayers before tax authorities and may be a cost-effective option for smaller audits
  • Sales tax-specific consultants: many states have non-CPA consultants who specialize exclusively in sales tax compliance and audit defense; these can be very effective and cost-efficient for standard audits
  • Cost ranges: sales tax audit representation typically runs $2,000-10,000+ for routine audits depending on complexity and duration; tax attorney representation in contested or litigation scenarios can run significantly higher
  • Get multiple quotes: audit representation fees vary widely; get at least two quotes and ask specifically about their experience with the auditing state

Frequently asked questions

Do I need a tax attorney or a CPA for a sales tax audit?
For most routine sales tax audits, verifying returns, resolving nexus questions, producing exemption certificates: a CPA or sales tax consultant with SALT (state and local tax) experience is appropriate and usually more cost-effective than an attorney. A tax attorney becomes necessary when there are fraud allegations, potential criminal exposure, the audit escalates to litigation, or you need attorney-client privilege protection for sensitive communications.
What's the difference between a SALT specialist and a general CPA for a sales tax audit?
A general CPA handles income taxes and financial reporting; state sales tax is a specialized area with its own rules, administrative procedures, and negotiation dynamics. A SALT specialist knows audit protocols, understands how to negotiate with state auditors, is familiar with the specific state's procedures, and can identify contestable findings. A general CPA without SALT experience may not know which audit findings are worth contesting or how to do so effectively.
