San Antonio Sales Tax Attorneys – Detecting Sampling Errors!

Don’t settle for less when it comes to sales tax litigation. Many firms may try to negotiate a reduced debt or payment plan without the necessary expertise. At the Ansari Law Firm, we possess the seasoned insight garnered from litigating countless sales tax cases in San Antonio. For instance, if you were audited for unpaid sales tax on raw materials sold to another retailer, our response would be clear: “No, you do not owe any sales tax as this constitutes a business-to-business transaction, with these materials being classified as business inputs and therefore non-taxable.” Such precision comes only with years of experience litigating tax cases.

In addition to our core services, we assist clients with:

  • 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
