The IRS reminds tax professionals to renew their Preparer Tax Identification Numbers (PTINs) for the 2025 tax season. Current PTINs expire on December 31, 2024, and the renewal fee is $19.75. The renewal process can be completed online in about 15 minutes, or by using a paper form, which may take up to six weeks. First-time applicants can also apply online. All tax professionals who prepare most types of tax returns, as well as all active Enrolled Agents, are required to renew their PTIN on an annual basis.   For more details, visit the IRS website.
