Does the 2026 Gulf War Presumption Deadline Still Apply?

CCK Law: Our Vital Role in Veterans Law

No, the Dec. 31, 2026, deadline for manifestation of symptoms related to Gulf War service should no longer apply to veterans. This is due to the passage of the 2022 PACT Act, which rewrote the underlying law to make it so that a qualifying Gulf War illness can manifest at any time and still be covered by the relevant presumptions.

Despite this, confusion surrounds this defunct deadline because the Department of Veterans Affairs’ (VA) own regulations have currently not yet been updated to account for the PACT Act revisions, even though VA has acknowledged that the revisions themselves should apply.

This article explains what changed, why the regulation and the statute disagree, and who still qualifies for the Gulf War presumption today.

A few key points before the details:

• Section 405 of the PACT Act amended 38 USC § 1117 in August 2022, removing the manifestation-period requirement for Gulf War illness claims.
• VA’s regulation, 38 CFR § 3.317, still lists the old Dec. 31, 2026, date and has not been updated to match the statute.
• Veterans already receiving benefits under the Gulf War presumption keep that eligibility no matter what happens to this date.

What Did the Dec. 31, 2026, Deadline Originally Require?

Under 38 CFR § 3.317, the Dec. 31, 2026, deadline required that a veteran’s Gulf War-related condition manifest to such a degree that their symptoms would reach at least a 10 percent disability rating by this date. If a veteran’s symptoms did not manifest to such an extent by this deadline, that veteran would not qualify for presumptive service connection for their Gulf War illness.

However, the Dec. 31, 2026, deadline is not the first to have existed for this specific purpose. In fact, this deadline has been extended several times in the past. The first such deadline was in 2001, but that got extended to 2006, then to 2011, then to 2016, then to 2021, and finally to 2026. A big reason for these multiple extensions was the ongoing medical uncertainty over when Gulf War-related conditions typically appear.

It is important to note that this deadline was not a claim submission deadline, but a symptom manifestation deadline. As long as the veteran had documented symptoms that reached the 10 percent level before the deadline, they could still file their actual disability claim after the deadline and not lose out on the presumption. However, if the veteran’s symptoms only appeared after this deadline, then the presumption would not apply.

In 2021, Congress decided that, rather than extend this deadline past 2026, it would be better to address the problem in a different way: by rewriting the underlying law so no future extension would ever be needed. This change was passed as part of the 2022 PACT Act.

How Did the PACT Act Change the Gulf War Presumption?

Section 405 of the PACT Act amended 38 USC § 1117 in August 2022, getting rid of the Dec. 31, 2026, deadline and replacing it with a single new standard: A qualifying chronic disability may become manifest to any degree at any time and not impact a veteran’s eligibility for Gulf War presumptions.

This amendment removed both pieces of the old rule at once — the requirement that a condition reach 10 percent disabling, and the requirement that it do so by a specific date.

For example, say a veteran developed sleep disturbances as a result of their Gulf War service, but their symptoms did not manifest to a 10 percent degree until March 2027 (i.e., after the Dec. 31, 2026, deadline). In this case:

• Under the old regulation, that veteran would have been locked out of the presumption entirely.
• Under the PACT Act’s current amended statute, timing no longer matters, nor does the degree to which the veteran’s condition manifested itself. The veteran would not be locked out of the presumption even though their symptoms appeared after the 2026 deadline, nor would those symptoms need to reach a 10 percent degree to qualify.

Why Does VA Still List the Gulf War Manifestation Deadline?

Simply put, 38 CFR § 3.317 still lists the old Dec. 31, 2026, deadline because VA has not finished updating the regulation to match the amended statute.

In October 2024, VA published a proposed rule acknowledging that Section 405 of the PACT Act removed the manifestation-period requirement and proposing to remove the outdated language from § 3.317. As of this writing, however, VA has not finalized that change, so the regulation’s text and the statute it implements say two different things.

This is important because, when a regulation conflicts with the statute it implements, it is the statute that wins out. In other words, VA’s regulations regarding this deadline are now incorrect, and it is legally bound to enforce the amended statute that Congress passed with the PACT Act.

Ultimately, this discrepancy between the amended statute and the regulations as written is the source of much of the confusion surrounding this topic, since most veterans reading over VA’s regulations would assume them to be correct, rather than outdated.

Who Qualifies as a Gulf War Veteran Under This Presumption?

To qualify for the Gulf War presumption, veterans need active military, naval, or air service in a recognized Gulf War location on or after August 2, 1990. Notably, the PACT Act also broadened this list well beyond the original Southwest Asia theater.

Veterans should be aware that the six new countries added here by the PACT Act are in the amended statute but as of writing are not yet added into 38 CFR § 3.317, as is the case with the removal of the manifestation deadline.

The table below lists the locations and dates in which a veteran needs to have served to qualify for Gulf War presumptions:

Importantly, Reserve and National Guard members qualify on the same terms as active-duty veterans, as long as they served in one of these locations during a qualifying period. Additionally, veterans should note that branch of service and rank do not affect eligibility — only where and when the veteran served.

What Conditions Are Covered Under the Gulf War Presumption?

VA groups Gulf War presumptive conditions into three general categories: undiagnosed illnesses, medically unexplained chronic multisymptom illnesses (MUCMIs), and certain infectious diseases.

Importantly, the removal of the manifestation deadline applies to the undiagnosed-illness and MUCMI categories. The nine covered infectious diseases adhere to separate rules regarding service location and timing, per 38 CFR § 3.317(c).

The table below lists examples from each of these categories:

Veterans should note that each of these categories carries its own documentation requirements. For instance, a MUCMI diagnosis works differently from an undiagnosed illness claim. Symptoms generally need to have lasted six months or more to count as chronic, and VA will look at the veteran’s service treatment records and any post-service medical evidence to establish when symptoms began.

Frequently Asked Questions

What happens if your symptoms manifest after Dec. 31, 2026?

For a veteran whose qualifying symptoms first reach a compensable level after Dec. 31, 2026, the amended 38 USC § 1117 no longer conditions the presumption on a manifestation date, though VA has not finished aligning its regulation to say so explicitly. Nothing changes for veterans who already have a service-connected Gulf War presumptive condition — that rating stays in place regardless of this date.

Does the new CDC diagnostic code change how VA rates Gulf War Illness?

Not yet. The Centers for Disease Control and Prevention (CDC) added a dedicated diagnostic code, T75.830, for Gulf War Illness in October 2025. VA has said adding this code to a veteran’s medical record is not required to receive VA care, and it has not added Gulf War Illness as its own presumptive condition with a dedicated rating. Veterans’ advocacy groups are pushing VA to make that change.

How is the Gulf War presumption different from other PACT Act presumptions?

Most PACT Act presumptions, like those for burn pit-related cancers and respiratory conditions, link a specific disease to a type of exposure without ever requiring a manifestation deadline. The Gulf War presumption is older and more specific: It covers undiagnosed illness and medically unexplained chronic multisymptom illness rather than named diseases, which is why it developed its own manifestation-period history that the PACT Act had to separately correct.
