The Internal Revenue Service regularly performs tax audits of both corporate taxpayers and individuals. Although tax audits are conducted year-long, they often spike during the few months after the tax season, especially when problematic or misleading returns come under the IRS microscope. Irrespective of when an “examination” or audit commences, an IRS auditor would be assigned to your case. While IRS tax auditors are trained to be efficient, they’re also well trained to be comprehensive and thorough – and depending, to a large extent, on the structure and complexity of the individual or company’s tax situation, the IRS audit process usually takes more time than you may estimate as a taxpayer.
