A completed Tax Form St 100 (2020) can be retained electronically when the record remains accurate, accessible, and reproducible.

Tax Form St 100 (2020) troubleshooting
Resolve document, signer, submission, and retention questions before treating the return as complete.
Upload the original Tax Form St 100 (2020) PDF again, then review auto-detected fields before sending. signNow Business includes templates and audit trails; confirm that the state’s required fields and submission method remain unchanged.
Check that the signer’s email address is correct and resend the invitation from signNow. SMS authentication may require a valid mobile number, while the Business Premium plan adds quick invite links for alternate delivery.
A completed signNow document does not automatically constitute a state filing. Review New York Department of Taxation and Finance instructions, submit through the required channel, and retain proof of submission with the signed return.
Use the signNow audit trail and completion certificate to document intent, identity, timestamps, and actions. ESIGN and UETA recognize qualifying electronic signatures, but state filing rules and tax-record requirements still apply.
Business includes templates, mobile apps, and audit trails at $8/user/month when billed annually. Business Premium is $15/user/month and adds bulk send; plan limits and invite usage should be checked before high-volume returns.
Export the signed PDF and audit trail from signNow, then store them under the applicable tax-record policy. IRC §6501(a) generally uses three years from filing, with longer periods for specified circumstances.
