How do I get my 5-digit Electronic Filing PIN?
To e-file your taxes, the IRS needs to verify your identity (and your spouse's, if you're filing jointly) with a 5-digit Electronic Filing PIN.
Simply click here (or call 1-866-704-7388) to get your official PIN from the IRS's Electronic Filing Service.
The IRS will request a few pieces of information from last year's tax return for verification purposes. Once you've provided it, you'll get your 5-digit PIN so you can e-file your 2015 return. (You'll also need to request a separate PIN for your spouse if you're filing a joint return.)
Your assigned PIN can only be used to e-file your 2015 return, so there's no need to memorize it or write it down for next year.
