"I Never Agreed to File Jointly": Forged Signatures and Returns Signed Under Duress

Everything in innocent spouse law starts from one assumption: you filed a joint return. But what if you did not? What if your spouse signed your name without asking, or you signed only because you were afraid of what would happen if you refused? In those cases, the right question may not be whether you qualify for relief from a joint return. It may be whether a valid joint return exists at all.

That distinction can matter more than anything else in your case.

Why the joint return question comes first

Joint and several liability comes from Internal Revenue Code section 6013(d)(3): "if a joint return is made," liability is joint and several. Innocent spouse relief under section 6015 relieves people from liability on a joint return. Both depend on a valid joint return.

If there is no valid joint return as to you, you are not jointly liable in the first place. The question is not whether you lacked knowledge or whether it would be inequitable to hold you liable. It is the earlier question that section 6015 assumes has already been answered: whether you made a joint return at all.

Signatures

Treasury Regulation 1.6013-1(a)(2) says a joint return, if not made by an agent of one or both spouses, shall be signed by both spouses. IRS Publication 504 puts it simply: both you and your spouse must generally sign the return, or it will not be considered a joint return.

That does not mean every unsigned return is automatically separate. The Form 8857 instructions note that by law, if a person's name is signed to a return, it is presumed to be signed by that person unless that person proves otherwise. The burden of showing the signature is not yours falls on you. And Form 8857, at line 11, asks whether you intended to file a joint return, because intent is part of the inquiry.

Duress

Treasury Regulation 1.6013-4(d) addresses duress directly. If an individual asserts and establishes that he or she signed a return under duress:

• The return is not a joint return.
• The individual who signed under duress is not jointly and severally liable for the tax shown on the return or any deficiency.
• The return is adjusted to reflect only the tax liability of the individual who voluntarily signed it, computed at the rates for married individuals filing separately.
• Section 6212, the notice of deficiency provision, applies to assessing any deficiency on that return.

Treasury Regulation 1.6015-1(b) cross-references this rule for innocent spouse purposes.

What the Form 8857 instructions say

The instructions for line 11 of Form 8857 lay out the IRS's approach:

• If you believe your signature was forged or you signed under duress, explain in the space provided.
• If your signature was forged or you signed under duress, the election to file jointly is not valid and you have no valid joint return.
• If the IRS determines your signature was not valid, you will be removed from the account and will no longer be liable for any taxes owed for that return.
• If it is ultimately determined that a valid joint return was filed, the IRS will then consider whether you are entitled to innocent spouse relief.

That last point is important. Raising forgery or duress on Form 8857 does not waive innocent spouse relief. The IRS considers the joint return question first, and relief second. File the form, answer every question, and explain the signature problem on line 11.

Duress versus abuse

Duress and abuse overlap, but they are not the same thing in the tax rules.

Duress, under Treasury Regulation 1.6013-4(d), goes to whether you signed voluntarily. If you did not, there is no joint return.

Abuse, in the sense used in Revenue Procedure 2013-34, describes abuse "not amounting to duress." It covers situations where you signed, but abuse or fear of retaliation kept you from questioning the return or the payment of tax. It works within the section 6015 framework, turning factors in your favor.

Section 6015(c)(3)(C) ties the two together for separation of liability: the actual knowledge bar does not apply where the individual with actual knowledge establishes that he or she signed the return under duress. And Treasury Regulation 1.6015-3(c)(2)(v) says that a requesting spouse who involuntarily executed the return may choose to establish duress, in which case Treasury Regulation 1.6013-4(d) applies.

In practice, I often present both: duress as to the signature, and, in the alternative, abuse within the section 6015 analysis. If the IRS concludes that the signature was voluntary, the abuse facts are still in the record. See the guide to abuse and financial control.

What evidence looks like

For forgery, the questions are factual. Were you available to sign? Do your known signatures match? Was the return electronically filed by your spouse without your participation? Did you know a joint return was being filed at all? Did you file your own return for that year? Did you behave as though a joint return had been filed, for example by receiving part of a joint refund?

For duress, the questions are about coercion at the time of signing. What happened when the return was presented to you? Were there threats, physical intimidation, or a history that made refusing feel unsafe? Was there anyone who witnessed the circumstances or their aftermath? Form 8857 Part V lists the kinds of documentation the IRS invites for abuse: protection or restraining orders, police reports, medical and counseling records, injury photographs, and statements from witnesses.

Be honest about the hard facts. If you signed willingly and later regretted it, that is not duress. If you received the benefit of a joint return and said nothing for years, expect the IRS to raise it.

Electronic filing and the signature question

Most joint returns today are filed electronically, and many couples never see a paper signature line. That does not make the signature question go away. It changes the evidence. Who had access to the return and the filing software? Who entered the signature information? Did you review the return before it was transmitted, or learn about it only when the IRS wrote? Were you even in the same place at the time? Line 12 of Form 8857 asks about your involvement in preparing the returns, whether you reviewed them, and whether you agreed to file or knew the returns were filed. Answer those questions with specifics.

How this fits with a section 6015 request

Treat the signature issue and section 6015 relief as layers of the same request:

1. First layer: no valid joint return. Forgery, lack of intent to file jointly, or duress under Treasury Regulation 1.6013-4(d).
2. Second layer: relief under section 6015. If the IRS finds a valid joint return, innocent spouse relief, separation of liability and equitable relief, all on the same Form 8857.
3. Third layer: the abuse rules. Even without duress, abuse and financial control can change the actual knowledge rule under section 6015(c) and the factors under Revenue Procedure 2013-34.

Because the IRS considers innocent spouse relief only if it finds a valid joint return, presenting all three layers at once protects you without forcing you to choose.

The consequences of winning

If there is no valid joint return as to you, the IRS treats the return as your spouse's separate return under Treasury Regulation 1.6013-4(d), computed at married filing separately rates. That can increase your spouse's tax. It also means you may have your own filing obligation for that year if you had income. Plan for that. A clean separate return for your own income may be part of resolving the case.
