What Is a Preparer Tax Identification Number?
A preparer tax identification number (PTIN) is an Internal Revenue Service (IRS) identifier implemented in 1999 that has required all paid federal tax return preparers to register with the federal government and obtain a unique number since 2010. Tax preparers are any individuals who prepare, calculate, and file income tax returns on behalf of individuals or businesses, and receive compensation for their services. Preparer tax identification number applicants must provide satisfactory answers to several suitability questions to receive a preparer tax identification number. Tax preparers must renew their preparer tax identification numbers each calendar year.
