Dallas Sales Tax Attorneys – Detecting Sampling Errors!

When it comes to sales tax litigation, settling for anything less than expert guidance can be a costly mistake. Many firms may attempt to negotiate reduced debts or payment plans without the necessary depth of expertise. At the Ansari Law Firm, our seasoned insight is derived from a wealth of experience litigating numerous sales tax cases in Dallas. For instance, if you find yourself audited for unpaid sales tax on raw materials sold to another retailer, our response is unequivocal: “No, you are not liable for sales tax as this transaction falls within the realm of business-to-business, with the materials classified as business inputs and thus non-taxable.” Such precision is the result of years spent litigating tax cases, ensuring that our clients receive the most informed and effective representation possible.

In addition to our core services, we also assist clients and businesses 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
