Welcome to Associated Sales Tax Consultants, your complete sales and use tax resource, where you can count on experience, integrity and results.

“ASTC saved us more than 2.5 million dollars.”
Kent Sutton, CEO C4 Holdings, Inc.
Since 1980 Associated Sales Tax Consultants (ASTC) has represented thousands of clients, from sole proprietors to multinational corporations, including virtually every type of business that is subject to sales or use tax. Whether you’re looking for help with sales tax audit defense and appeals, claims for refund, compliance issues, exposure analysis, or aircraft and vessel exemptions, our specialists will provide the expertise you need.
In addition to serving thousands of clients, ASTC has successfully lobbied to pass legislation; filed lawsuits to gain access to state-held taxpayer records; and been instrumental in establishing the California Taxpayer Bill of Rights. Our principals have authored dozens of industry related articles and two books on sales and use tax matters: the Multistate Guide to Sales and Use Tax Audits and the Multistate Guide to Sales and Use Taxation: Construction Industry . Both books are published by CCH, Inc. and updated annually.
Our sales tax consultants include former sales and use tax auditors, supervisors and audit reviewers. Our inside knowledge of agency policies and procedures more than offsets the auditor’s usual advantage in interpreting and applying sales and use tax laws and regulations.
One reason we excel at what we do is because our consultants only deal with sales, use and similar excise tax matters throughout the country. Rather than competing for clients, we prefer to partner with high-quality legal and accounting firms. An ASTC partnership allows your professional firm to offer additional marketable services, including sales and use tax audit defense, reverse audits and refund claims, compliance solutions, aircraft and vessel exemptions and protection from unintended sales and use tax consequences of mergers, consolidations, dissolutions and asset transfers. Make ASTC your sales and use tax resource!
Planning to buy an aircraft, vessel or recreational vehicle? Sign up for and follow the ASTC Transaction Analysis Program and we’ll guarantee that you will legally avoid sales and use tax on your purchase.
