XYZ Letters Services

At Miles Consulting Group, we recognize the complexities of sales tax compliance in today’s regulatory landscape, especially following the landmark South Dakota v. Wayfair decision. As states enact economic nexus laws, vendors are increasingly sending XYZ letters to customers, requesting information on sales tax obligations for prior transactions. These letters serve as an essential tool for sellers to ensure compliance by confirming whether purchases are exempt or if sales tax needs to be collected.

An XYZ letter is typically sent when vendors are preparing to comply with new sales tax requirements, addressing potential tax obligations from prior sales, or conducting audits. Receiving such a letter can disrupt daily operations; therefore, understanding your responsibilities and how to respond is crucial. Customers receiving these requests must verify their purchase details to determine whether sales tax is owed or if an exemption applies.

In full disclosure, we’re often on the originating/requesting side of such requests as we work with our clients to minimize prior tax exposure as they look to come forward in voluntary disclosure. Why be on the requesting side? Our clients typically undergo a comprehensive review of nexus, taxability and filing requirements.  They may find that they were obligated to collect sales tax on their sales in prior years but they did not (for myriad reasons). If they either can’t collect this tax now, retroactively from their customer, or prove that their customer already paid the tax themselves, then they are liable for that tax (plus penalties and interest). So, we help them craft a plan to reach out to their customers using the XYZ letter process.

Navigating the outreach process can be challenging, and it’s vital to send these letters promptly and accurately to mitigate potential liability. At Miles Consulting Group, we provide expert guidance on managing the process, ensuring both our client and their customers understand their obligations and protecting vendor relationships. Our team is equipped to help you assess your tax responsibilities and streamline your sales tax compliance strategy, so you can focus on your core business activities with confidence. Partner with us to stay informed and compliant with the evolving sales tax landscape, minimizing exposure and fostering solid business practices.

XYZ Letters

The 101 of XYZ


An XYZ letter is a formal communication sent from a vendor to a customer, addressing sales tax obligations related to prior transactions. It typically arises from the vendor’s need to comply with new sales tax regulations following the Supreme Court’s decision in South Dakota v. Wayfair. These letters ask customers to confirm whether sales tax has been paid or if the transaction qualifies for an exemption. The XYZ letter process serves as a method for vendors to confirm compliance, minimize potential tax liabilities, and maintain clear records of their sales tax practices.

Addressing an XYZ letter requires a careful review of the transactions in question. Begin by gathering all relevant purchase documentation, such as invoices and contracts. Respond to the letter by clearly identifying whether the purchased items are taxable, exempt, or if the sales tax has already been paid. It’s crucial to provide accurate information and any supporting documentation requested. Engaging with the vendor professionally and promptly is not only good business practice but also helps maintain strong relationships while ensuring compliance with sales tax obligations.
