Use a Form M 8379 2020 template to make your document workflow more streamlined.

What Form M 8379 means

Form M 8379 (2020) is the 2020 edition of the IRS injured-spouse allocation form used to separate one spouse’s share of income, deductions, credits, and payments from a joint federal tax obligation. The filer identifies both spouses, allocates relevant tax items, signs the request, and submits it with the applicable joint return or filing instructions. signNow can prepare the PDF, route assigned fields for electronic signatures, and preserve an audit trail, but it does not calculate the allocation or replace IRS filing requirements.

Form M 8379 (2020) separates spouses’ income, deductions, credits, and payments so the IRS can evaluate an injured-spouse allocation request.

Retain and archive Form M 8379 records

Preserve Form M 8379 (2020), supporting tax records, and signing evidence according to the applicable IRS retention rule and your organization’s legal hold policy.

Apply the correct IRS retention period

Keep the completed Form M 8379 (2020), supporting income records, and the signed audit trail together. For federal tax records, apply the IRS period under IRC §6501(a): generally three years from filing, six years when the 25% understatement rule applies, and longer when fraud or no return is involved.

Export the completed audit trail

Export the completed Form M 8379 (2020) and its audit trail after signing. Preserve signer identity evidence, timestamps, access events, and the final PDF in a read-only repository so the record can be reproduced if the IRS requests supporting documentation.

Protect taxpayer information during storage

Restrict access to Form M 8379 (2020) because it can contain taxpayer identification, income, and allocation information. Use role-based permissions, encrypt stored files, and record every download or change through the organization’s document-management controls.

Maintain a complete archival record

Name the file with the tax year, form edition, taxpayer identifier, and completion date. Keep the original upload, final signed copy, and related correspondence together, while following any longer state, litigation-hold, or accounting retention requirement.

Common Form M 8379 mistakes

Transcribing income, deductions, credits, and payments into the wrong spouse’s allocation column can change the requested injured-spouse calculation.
A missing signature, taxpayer identification number, or supporting schedule can delay review of Form M 8379 (2020) by the IRS.
Uploading an outdated edition instead of Form M 8379 (2020) can create field mismatches and require the document to be completed again.
Sending the form without confirming each spouse’s assigned fields can leave allocation entries unsigned or attributable to the wrong person.

Risks of mishandling Form M 8379

Incomplete IRS form

Rejected allocation

Missing spouse data

Processing delay

Incorrect allocation

Taxpayer dispute

Missing signature record

Weak evidence

Legal standing of Form M 8379 records

A completed Form M 8379 (2020) can be retained as an electronic business record when signer intent, consent, attribution, and accurate reproduction are demonstrated under ESIGN, 15 U.S.C. ch. 96, and applicable state law such as UETA. Those frameworks do not replace IRS filing instructions or authorize electronic execution of excluded documents such as wills or court orders.

Retention schedule for Form M 8379

Keep Form M 8379 (2020) with the underlying joint-return records and apply the longest retention period triggered by the tax facts or an active legal hold.

Three years from filing

IRC §6501(a) generally measures the federal tax-record period from the return filing date.

IRC §6501(e) provides a six-year period when gross income is understated by more than 25%.

Indefinite period for fraud

IRC §6501(c) permits an indefinite period for fraudulent returns.

Indefinite period without filing

IRC §6501(c) provides an indefinite period when no return is filed.

Longer period when required

State rules, litigation holds, or related tax records may require a longer period than the federal baseline.

Form M 8379 troubleshooting

Resolve Form M 8379 (2020) issues by checking field assignment, signer consent, tax-record retention, and the signNow plan capabilities used for the workflow.

Upload the original Form M 8379 (2020) PDF again, then inspect automatically detected fields before sending. signNow’s Business plan includes templates and audit trails, but field detection does not validate tax calculations or determine whether a spouse’s allocation is correct. Review every amount against supporting records.

Assign every signature, date, and tax-information field to the correct spouse before delivery. signNow lets the sender route fields by signer; an electronic signature is attributable when intent, consent, and the signer’s identity are documented under ESIGN and applicable state law.

Business includes legally binding eSignatures and audit trails at $8 per user per month with annual billing. Subscription plans include 100 signature invites per user per year, with overage fees; the Site License is the usage-based option for higher document volumes.

For consumer-facing electronic records, provide the ESIGN consumer disclosure and confirm the person can access the electronic format. Under 15 U.S.C. §7001(c), consumers must also have a way to withdraw consent and request paper records.

signNow lists HIPAA compliance with a BAA requirement, but Form M 8379 is a tax document and should not be placed in a healthcare workflow unless protected health information is genuinely involved. Apply IRS confidentiality controls and restrict access to authorized personnel.

Use signNow’s audit trail to preserve timestamps, signer actions, and completion evidence, then download the final PDF and audit trail together. Retain tax records under IRC §6501(a): generally three years from filing, subject to longer statutory periods.
