Handling IRS Problems While Deployed: Military POAs, Form 2848 and Signing for a Spouse

An IRS notice arrives at home. The servicemember is deployed. The spouse calls the IRS and hears the words every military family dreads: "I can only speak to the taxpayer." This guide explains how to avoid that dead end.

Two different questions

People mix these up. There are two separate issues:

1. Representation. Who can talk to the IRS, receive information and act on the servicemember's behalf?
2. Signing returns. Who can sign a tax return, especially a joint return, when one spouse is away?

Different documents answer each one.

Representation: the military power of attorney

IRM 5.1.7.10.3.5 addresses this directly. It says a military POA is sufficient authorization to permit an individual to represent a deployed member of the military before the IRS. The manual notes the holder is often the spouse.

There is a practical wrinkle. The manual explains that because a military POA is broader than an IRS form and cannot be input into the IRS's Centralized Authorization File (CAF), the IRS may require the non-deployed spouse or other military POA holder to complete Form 2848, Power of Attorney and Declaration of Representative. The spouse is permitted to sign the Form 2848 for the military member and as the authorized representative. A copy of the military POA should be attached.

The manual adds a simpler route: a Form 2848 signed by the military member and the authorized representative, including a spouse or other family member, is sufficient for representation.

Best practice: sign a Form 2848 before you deploy. Bring a copy of the military POA as a backup.

Form 2848 versus Form 8821

• Form 2848 lets a representative act for you before the IRS, within the authority you grant. It is the document a spouse or attorney needs to negotiate a payment plan, respond to an audit or request penalty relief.
• Form 8821, Tax Information Authorization, lets someone receive and inspect your tax information but not represent you. It is useful when a family member just needs to see transcripts and notices.

Either way, list the specific tax matters and years. A Form 2848 that covers income tax for the last several years and the next few is much more useful than one that covers a single year.

Signing a joint return when a spouse is away

IRS Publication 3 for 2025 returns lays out the options.

Spouse overseas

The spouse expected to be overseas on the due date can file Form 2848 specifically designating the spouse who remains in the United States to sign the return for the absent spouse. Or one spouse can prepare and sign the return and send it to the other in time to sign and file by the due date.

Spouse in a combat zone

Publication 3 says that if your spouse cannot sign because of combat zone service and you do not have a power of attorney or other statement, you can sign for your spouse. Attach a signed statement explaining that your spouse is serving in a combat zone.

Spouse incapacitated

If a spouse is incapacitated, Publication 3 says the other spouse can sign the incapacitated spouse's name followed by "by [your name], Husband (or Wife)," with a dated, signed statement attached listing the form number, tax year, the reason the spouse cannot sign, and that the spouse has agreed to the signing.

Spouse missing

Under IRC 6013(f), a spouse of a servicemember in missing status as a result of combat zone service may elect to file a joint return for tax years beginning not more than two years after the date combatant activities in the zone end.

Combat zone documentation is a separate step

Representation lets your spouse talk to the IRS. It does not by itself tell the IRS you are in a combat zone. That requires substantiation: orders, a DoD statement, or in some cases a signed statement from you, your spouse or an attorney. See proving combat zone status to the IRS.

What a spouse can do without any authorization

Even with no paperwork in place, a spouse is not helpless. On a joint account, each spouse is a taxpayer in their own right, so the spouse at home can generally discuss the joint liability. A spouse can also send the IRS a signed statement substantiating combat zone service, which IRM 5.1.7.10.2 accepts when orders are not easily accessible. What a spouse cannot do without authority is act for the servicemember on matters that belong only to the servicemember, such as a separate return or a separate balance. That is where the military POA and Form 2848 come in.

A predeployment tax checklist

1. Sign Form 2848 naming your spouse or a trusted person for income tax for the relevant years.
2. Execute a military power of attorney through your legal assistance office and keep a copy with your tax papers.
3. If you expect to be away on the due date, sign a Form 2848 that specifically authorizes your spouse to sign your return.
4. Make sure your spouse knows where your W-2s, prior returns and IRS letters are.
5. Set up IRS online account access if you can, so someone can check balances and notices.
6. If you owe, consider setting up a payment plan before you leave. See installment agreements.
7. Write down your expected deployment dates for the combat zone extension. See the combat zone deadline extension.

When a lawyer is the representative

An attorney representing you files a Form 2848 signed by you. If you are deployed and cannot sign, the IRS manual's approach to military POAs applies: the military POA holder can sign Form 2848 for you. Many deployed families end up with two representatives on file, the spouse for day-to-day matters and a lawyer for the problem. That is fine. Form 2848 allows more than one.

Ten minutes with a form before deployment can save months of frustration while you are gone. Do it now.
