Personal income tax audits are a fact of life in many states. However, both New York State and New York City are particularly aggressive in pursuing this source of income, focusing mainly on questions of residency and non-resident income allocation. These audits can often be tremendously burdensome, even for those filing correctly. In this new edition of the New York Residency and Allocation Audit Handbook, noted tax practitioners Paul Comeau, Tim Noonan and Mark Klein provide an in-depth and practical look at New York's residency and income allocation audit programs. They include detailed, yet easy-to-read, information drawn from the current tax law and from their own experiences. This helpful book guides the reader through both the residency and the non-resident allocation audit process, starting with detailed descriptions of the residency and non-residency allocation "rules of the road" through practical advice on what to do when audited, how the audit will progress and techniques to use to help reduce the risk of an audit and minimize the problems. This publication also details civil penalties and interest, and the risk of criminal prosecution. Finally, the book explores the tax relationships between New York and other states, including a residency tax guide that summarizes the residency rules and requirements of the remaining states.
