Do You Need a PTIN? A Guide for New Tax Preparers

If you prepare, or help prepare, any federal tax return for compensation, the IRS requires you to have a valid Preparer Tax Identification Number (PTIN) and to include it on every return you sign. This applies regardless of whether you're a CPA, EA, or unenrolled preparer, credential level doesn't exempt you from the PTIN requirement, it only affects what else you're allowed to do (like represent clients before the IRS).

Who actually needs one

Anyone paid to prepare or substantially assist in preparing a federal tax return needs a PTIN. This includes bookkeepers who prepare returns as a side service, not just firms whose primary business is tax prep. If you only prepare your own return, or you're an unpaid volunteer preparer, you don't need one. If you're preparing returns for clients and charging for it, the requirement applies from your very first paid return.

How to get one

Applying is done directly through the IRS's PTIN requirements page, which links to the online application system. The online application typically takes about 15 minutes, and most PTINs are issued immediately upon completion. There's a modest annual renewal fee, and PTINs must be renewed each year before they expire at the end of the calendar year, an easy thing to let slip if it's not on your calendar.

What happens if you skip it

Preparing paid returns without a valid PTIN, or letting one lapse and continuing to prepare returns, can result in IRS penalties per return, plus potential referral for further enforcement in repeat or willful cases. Given that the application is free of real friction and the fee is minor, there's little reason to risk it.

PTIN vs. EFIN: don't confuse them

A PTIN identifies you as a preparer, an EFIN (Electronic Filing Identification Number) authorizes your firm to e-file returns with the IRS. Most firms need both: a PTIN for each individual preparer, and one EFIN for the firm or location doing the e-filing.

The bottom line

If you're paid to prepare federal returns, get a PTIN before your first paid return and calendar the annual renewal. It's a fast, low-cost requirement that's easy to handle correctly and genuinely risky to skip.
