New Book From CCH Details Use Of Statistical Sampling In Sales And Use Tax Audits

(RIVERWOODS, ILL., July 12, 2002) – When a state audits a company’s sales and use taxes, the stakes can be high and missteps can be costly. When the state auditor wants to use statistical sampling in a sales tax audit, everyone involved must take special care to avoid statistical pitfalls that can lead to incorrect assessments. To help all concerned make sure that statistical sampling is applied correctly, CCH INCORPORATED (CCH), a leading provider of tax and business law information and software, has published Statistical Sampling in Sales and Use Tax Audits, by noted expert and author Will Yancey, Ph.D. and CPA.

Statistical sampling is a practical and logical way to conduct audits when it is impractical to examine every single transaction, and states have been increasingly relying on this audit technique, according to John Logan, JD, senior tax analyst for CCH.

"Statistical sampling is replacing block sampling, in which an audit would look at every transaction in a given time period. This makes it imperative for business taxpayers and government agencies alike to have a sound understanding of the statistical, accounting, legal and information systems issues involved in this technique," Logan said.

Detailed, Critical Issues

From the scheduling of an audit to a potential appeal of the results, taxpayers have decisions to make. The purpose of this volume is to give taxpayers an understanding of the audit process and help them make decisions that will lead to a positive outcome.

Author Yancey begins with an overview of the legal and accounting environment for sales and use tax audits and lays the foundation for a deeper understanding of the issues involved. He then takes the reader through each step involved, such as population analysis and sample planning, provides a practical overview of the techniques of statistical evaluation and offers advice on negotiating with the state over disputed transactions. A separate reference chapter includes extensive bibliographies of tax audit sampling and sampling theory, as well as software applications and publishers for data extraction and population analysis and for statistical sample evaluation.

Yancey provides practical guidance on dealing with computer-assisted audit techniques and checking data files before sampling. Detailed but critical issues, such as which data files to use, distinguishing between billing and delivery addresses to determine nexus and identifying which date fields are determinative are all addressed.

An especially useful feature is an extensive summary of relevant law and administrative guidance on sampling for all states that impose sales and use taxes. This state-by-state treatment cites relevant statutes, regulations, rules, administrative law decisions and court cases.
