An Electronic Filing Identification Number (EFIN) is a unique alpha-numeric code assigned to authorized e-file providers. The EFIN is used to identify the e-file provider and to ensure the secure transmission of tax returns and other tax-related documents. To obtain an EFIN, you must complete and submit an Application for an Electronic Filing Identification Number (Form 8633) to the IRS. Once your application is approved, you will be issued an EFIN.
There are many benefits to obtaining an EFIN. EFIN holders can e-file tax returns and other tax-related documents, which can save time and money. EFIN holders can also access a variety of IRS online services, such as the e-Services portal. Additionally, EFIN holders are required to meet certain security standards, which helps to protect taxpayer data.
