Frequently Asked Questions

Does the IRS accept e-signatures on all tax forms?

No, but the IRS accepts e-signatures on most commonly used forms including Forms 8879, 8878, 4506-T, and 2848. Some forms still require wet signatures. Check current IRS guidance for specific forms.

Can I use any e-signature platform for tax documents?

Yes, the IRS doesn't mandate specific platforms. The key is meeting IRS requirements for identity verification, intent, association, and retention—most reputable e-signature platforms satisfy these requirements.

How long must I retain e-signed tax documents?

Form 8879 and related e-signature records should be retained for three years from the return due date or the date the return was filed, whichever is later. Longer retention is advisable.

What if a client's e-signature is challenged?

E-signature platforms provide audit trails showing who signed, when, from what IP address, and other verification data. This evidence is typically stronger than what exists for paper signatures.

Can clients sign from their phones?

Yes. All major e-signature platforms support mobile signing. Clients can sign tax forms from phones or tablets—useful during tax season when speed matters.
