Houston Sales Tax Attorneys – Detecting Sampling Errors!

When facing sales tax litigation, settling for anything less than expert guidance can lead to costly errors. Many firms may attempt to negotiate without the necessary expertise, risking suboptimal outcomes. At the Ansari Law Firm, our seasoned insight is backed by extensive experience litigating numerous sales tax cases in Houston. For example, if you’re audited for unpaid sales tax on raw materials sold to another retailer, our response is clear: “You’re not liable for sales tax as this is a business-to-business transaction, with the materials classified as business inputs and therefore non-taxable.” This kind of precision only comes from years of experience litigating tax cases, ensuring that our clients receive the most informed and effective representation possible.

In addition to our core services, we also represent clients and businesses in the following matters:

  • Texas State sales and use tax audits and appeals
  • Defense for Tax Preparers
  • Management and appeals for IRS tax audits
  • IRS Tax Court appeals
  • Negotiations for Federal and State tax debts
  • USDA – EBT and SNAP Violation Appeals for retailers
