IRS Form 15109 – Request for Tax Deferment

IRS Form 15109 – Request for Tax Deferment – If you’re a military member or civilian contractor who has served in a combat zone, contingency operation, or hazardous duty station, you may qualify for valuable tax relief. IRS Form 15109, also known as the Request for Tax Deferment, allows eligible individuals to postpone certain tax obligations under Internal Revenue Code (IRC) Section 7508. This can provide significant financial breathing room during or after deployment. In this comprehensive guide, we’ll cover everything you need to know about Form 15109, including eligibility, how to fill it out, submission options, and key tips for success—all based on the latest IRS guidelines as of 2026.

Whether you’re dealing with a CP04 notice from the IRS or proactively seeking deferment, understanding this form can help you navigate your tax responsibilities more effectively. Let’s dive in.

What Is IRS Form 15109 and What Does Tax Deferment Mean?

IRS Form 15109 is specifically designed for individuals who have served in designated combat zones or similar high-risk areas. Its primary purpose is to request a deferment of tax payments and filing deadlines, giving you extra time to handle your taxes without penalties or interest accruing during the deferment period.

Tax deferment in this context means temporarily postponing:

  • Filing income tax returns.
  • Paying taxes owed.
  • Other time-sensitive tax actions, such as responding to IRS notices or audits.

This relief is rooted in IRC Section 7508, which recognizes the unique challenges faced by service members and civilians in hazardous duty. Deferment typically lasts for the duration of your service in the qualifying area plus 180 days after you leave. However, requesting it is optional—if you don’t need the extension, you can simply file and pay as usual.

The form is often prompted by an IRS CP04 notice, which the agency sends if your tax return indicates potential eligibility based on combat zone service. If you receive this notice, act promptly to avoid delays in processing your request.

Who Qualifies for Tax Deferment Using Form 15109?

Eligibility for Form 15109 is targeted at those directly impacted by service in high-risk areas. According to official IRS guidelines, you may qualify if you are:

  • A member of the U.S. Armed Forces (including Reserves and National Guard) deployed to a combat zone, contingency operation, or hazardous duty station.
  • A civilian employee working under a federal government contract in these areas.

Key qualifying locations include areas defined in Publication 3, Armed Forces’ Tax Guide, such as Afghanistan, Iraq, or other designated zones. Your service must have begun or ended during the tax year in question or the period referenced in your IRS notice.

Important notes on eligibility:

  • Spouses of qualifying individuals may also benefit if filing jointly.
  • The deferment applies to federal income taxes but does not automatically extend to state taxes—check with your state revenue department.
  • If you’re unsure about your location’s status, refer to the IRS’s list of combat zones in Publication 3.

Failing to meet these criteria or providing incomplete information could result in denial, so gather your documentation early.

Required Documentation for Form 15109

To support your request, you’ll need to attach proof of your service. The IRS requires one of the following:

  • For military personnel: A copy of your military orders showing deployment dates to the combat zone or contingency operation.
  • For civilians: A Letter of Authorization from your employer or contracting agency.
  • Alternative if orders or letter are unavailable: A written statement from your employer or organization detailing the dates and location of your service in the qualifying area.

Without these documents, your request may be delayed or denied. Always keep originals for your records, as the IRS may request additional verification.
