Generally, Your Return Must Be Postmarked By April 15

Use a Generally, Your Return Must Be Postmarked By April 15, 2020 template to make your document workflow more streamlined.

What the April 15 statement means

“Generally, Your Return Must Be Postmarked By April 15” describes the federal individual income-tax filing deadline, not a standalone IRS form. For taxpayers filing by mail, IRC §7502 addresses when timely mailing may count as delivery; IRC §7503 addresses weekends and holidays. An extension request generally moves the individual return deadline to October 15, but payment is not automatically extended. signNow can prepare and e-sign supporting records, capture an audit trail, and store the completed document; IRS instructions still control filing method, payment, postmark, and acceptance.

Avoid April 15 filing mistakes

Confusing an April 15 filing deadline with a postmark can lead to missing the IRS rule that applies to the actual return or extension request.
A signNow completion certificate records signing activity, but it does not independently prove USPS mailing, IRS receipt, payment, or electronic submission.
Using an outdated deadline or assuming every taxpayer receives the same deadline can produce incorrect filing instructions and avoidable late-filing exposure.
Separating signed supporting records from filing confirmation makes it harder to reconstruct who approved the document and when the tax package was completed.

Best practices for April 15 records

Accurate deadline evidence requires two records: the signed document and independent proof of filing, mailing, payment, or IRS receipt.

Confirm the applicable IRS filing rule

Confirm the applicable IRS deadline before sending any April 15 document. IRC §7503 addresses weekends and holidays, while IRC §7502 concerns timely mailing; retain the separate proof that matches the filing method used.

Pair the audit trail with filing proof

Export the signNow audit trail after completion and store it with the signed April 15 record. The audit trail supports signer attribution and chronology, but it does not replace IRS acceptance or mailing evidence.

Restrict access to taxpayer information

Protect taxpayer information through restricted access, accurate recipient addresses, and secure archival. Consumer-facing records may also require the consent and access procedures described in ESIGN, 15 U.S.C. §7001(c).

Apply the correct tax retention period

Keep tax records according to the applicable IRS rule: generally three years from filing under IRC §6501(a), six years when income understatement exceeds 25 percent, and indefinitely for fraud or no return.

Questions about the April 15 deadline

These answers distinguish the April 15 tax deadline from signNow’s role in signing and preserving supporting records.

April 15 is the federal deadline for many individual income tax returns under IRC §7503. signNow can collect signatures on supporting records, but IRS filing instructions determine where and how the return is submitted.

A signed PDF does not establish a postmark. IRC §7502 generally recognizes timely mailing when statutory requirements are met, so retain authorized mailing or electronic-submission evidence separately from the signNow audit trail.

The Business plan includes templates and audit trails at $8/user/month when billed annually. It does not itself provide tax advice, calculate liability, or determine whether Form 4868 applies.

Business Premium costs $15/user/month annually and adds bulk send. That feature can distribute repeated signature requests for supporting documents, but it does not change the April 15 deadline or create an IRS extension.

signNow states ESIGN and UETA compliance, supporting intent, attribution, and record reproduction for electronic signatures. IRS rules still control tax-return filing, required forms, payment, and any electronic-record conditions.

The 7-day free trial requires no credit card, while paid plans include 100 signature invites per user annually. Review invite usage before sending multiple April 15 supporting documents.
