Individual Income Tax Return

Use a INDIVIDUAL INCOME TAX RETURN 2019 template to make your document workflow more streamlined.

What an Individual Income Tax Return does

An Individual Income Tax Return reports a U.S. taxpayer’s income, deductions, credits, tax liability, payments, and refund or balance due to the IRS. Taxpayers generally use Form 1040 and attach applicable schedules, statements, and supporting records. The federal filing deadline is April 15, with October 15 available when a taxpayer files Form 4868 on time; an extension does not extend payment of tax due. signNow can help prepare, route, sign, and retain the document record, but IRS filing instructions control submission and tax compliance.

Individual Income Tax Return challenges

Taxpayers may omit income, deductions, credits, or filing-status details, producing an inaccurate Individual Income Tax Return.
Paper-based review makes it harder to coordinate taxpayer signatures, preparer approvals, supporting schedules, and final records.
Manual copying between worksheets and the return can create mismatched figures across wages, interest, deductions, and tax payments.
Missing signed copies or supporting records can complicate responses to IRS questions after filing.

Individual tax record retention

Retention depends on filing accuracy, the extent of any understatement, fraud, filing status, and applicable state requirements.

Three years: federal tax records

Retain federal tax records for three years from filing under IRC §6501(a).

Six years: 25% understatement

Retain records for six years when income was understated by 25% or more under IRC §6501(e).

Indefinite: fraudulent return

Retain records indefinitely when fraud occurred under the IRS limitation rules.

Indefinite: no return filed

Retain records indefinitely when no return was filed under IRC §6501(c).

State period: verify locally

Apply longer state retention periods where state tax law requires them.

Record-keeping practices for tax returns

Accurate retention and controlled access help connect the signed return with the evidence supporting its reported amounts.

Retain supporting records with the return

Keep the filed return, schedules, income statements, deduction evidence, payment confirmations, and signed completion record together. Apply the three-year federal period from filing under IRC §6501(a), extending it when the 25% understatement rule or indefinite-retention conditions apply.

Export the audit trail after completion

Export the signNow audit trail with the completed return and record signer identity, timestamps, IP information, and document history. This evidence supports the electronic signing record but does not replace IRS filing confirmations or substantive tax documentation.

Limit access to taxpayer information

Restrict access to taxpayer identification numbers, income data, bank details, and attachments through role-based permissions. Review shared templates before reuse so outdated tax-year fields do not carry into a new Individual Income Tax Return.

Reconcile figures before signature

Reconcile every reported amount against source documents before signature, especially wages, interest, deductions, credits, estimated payments, and withholding. Correct discrepancies before sending rather than relying on the audit trail to explain inaccurate tax figures.

Individual tax return troubleshooting

Resolve field, signing, compliance, deadline, and retention questions without confusing signNow document handling with IRS filing obligations.

Upload the prepared return again and check whether the PDF contains selectable fields. signNow can detect fillable fields, but a scanned image may require manually placed fields before sending it to the taxpayer.

The Business plan includes audit trails, while Business Premium adds bulk send and kiosk mode. Review the plan configuration before expecting high-volume preparation or in-person signing features for tax workflows.

Electronic signatures can satisfy ESIGN and UETA requirements when intent, consent, attribution, and record retention are established. Consumer-facing records may also require the ESIGN disclosure and access requirements under 15 U.S.C. §7001(c).

Use SMS OTP or another configured authentication method to strengthen signer attribution, then verify the taxpayer’s identity independently when tax-preparation procedures require it. Authentication does not validate the accuracy of reported income or deductions.

The April 15 deadline applies to the individual federal return, while October 15 is available with Form 4868. The extension changes the filing date, not the deadline to pay tax owed.

Retain federal tax records for three years from filing under IRC §6501(a), six years when income was understated by 25% or more, and indefinitely for fraud or no return filed.
