IRS Form 8857 – Request for Innocent Spouse Relief (Fillable PDF)

Form 8857, officially titled Request for Innocent Spouse Relief, lets taxpayers ask the Internal Revenue Service (IRS) to remove or reduce their joint tax liability when they believe the spouse or former spouse is solely responsible for an error or underpayment. This page provides a fillable PDF version, a simple step‑by‑step guide, and answers to the most common questions.

What Is Form 8857 and Who Can Use It?

Form 8857 is used when you filed a joint return and later discover that the tax liability is the result of:

• Undisclosed income or fraudulent activity by your spouse,
• Errors you were unaware of at the time of signing,
• Coercion or duress that forced you to sign the return, or
• Significant financial hardship if you were held liable.

If any of these situations apply, you may qualify for innocent spouse relief, equitable relief, or separation of liability relief.

Common Mistakes to Avoid When Completing Form 8857

Even a small error can delay processing. Keep these tips in mind:

• Don’t leave any required boxes blank. If a question does not apply, write “N/A”.
• Provide supporting documentation. Attach copies of the joint return, notices, and any evidence of the spouse’s wrongdoing.
• Use the correct tax year. The year you are requesting relief for must match the year on the joint return.
• Sign both the taxpayer and spouse sections. If you have a paid preparer, they must also sign.
• Check the address. Mail the form to the IRS location specified in the instructions for your state.

Following these guidelines will help the IRS process your request faster.
