Thousands of veterans turn down part-time work every year because they believe any paycheck cancels Total Disability based on Individual Unemployability. The regulation says something narrower. Under 38 CFR 4.16(a), "marginal employment shall not be considered substantially gainful employment," and marginal employment generally exists when earned annual income does not exceed the Census Bureau poverty threshold for one person — $16,320 for a person under 65 in the most recently published Census table. The pain is real: fear of losing a total rating keeps veterans idle and isolated. This guide explains where the 2026 income line sits, what VA actually counts, and how to work inside the rule.
Key Takeaways
- Understand that TDIU pays at the 100 percent rate even though the schedular rating is less than total.
- Measure earned annual income against the Census poverty threshold for one person, not against household income.
- Recognize that a protected environment — a family business or sheltered workshop — can still be marginal employment above the threshold.
- File VA Form 21-8940 and expect VA to send Form 21-4192 to recent employers.
- Know that a TDIU rating cannot be reduced for returning to work unless the job is held 12 consecutive months.
- Verify every current figure on VA.gov before relying on it, because thresholds and rates change annually.

Who Qualifies for TDIU Under 38 CFR 4.16
The pain point comes first: a veteran can be too disabled to hold a real job and still sit at 70 percent on paper, drawing far less than the total rate. TDIU exists to close that gap. Under 38 CFR 4.16(a), a total rating may be assigned when the schedular rating is less than total and the veteran is unable to secure or follow a substantially gainful occupation as a result of service-connected disabilities.
The regulation sets percentage gates. If there is only one service-connected disability, it must be ratable at 60 percent or more. If there are two or more, at least one must be ratable at 40 percent or more, with enough additional disability to bring the combined rating to 70 percent or more. The regulation also groups certain conditions together as a single disability for that math: disabilities of one or both upper or lower extremities including the bilateral factor, disabilities from a common etiology or a single accident, disabilities affecting a single body system, multiple injuries incurred in action, and multiple disabilities incurred as a prisoner of war.
When the Percentages Are Not Met
Falling short of 60 or 70 does not end the inquiry. Paragraph (b) of the same section states the established VA policy that all veterans unable to secure and follow a substantially gainful occupation by reason of service-connected disabilities shall be rated totally disabled. Rating boards are directed to submit those cases to the Director, Compensation Service, for extra-schedular consideration, with a full statement of service-connected disabilities, employment history, and educational and vocational attainment. Veterans below the percentage gates should therefore build the same evidentiary record, not assume the door is closed.
The Income Line: What Marginal Employment Means
Veterans repeatedly hear a dollar figure quoted with confidence and no source. The regulation itself names the source rather than a number. Under 38 CFR 4.16(a), marginal employment "generally shall be deemed to exist when a veteran's earned annual income does not exceed the amount established by the U.S. Department of Commerce, Bureau of the Census, as the poverty threshold for one person." That figure moves every year, which is why a number memorized in 2022 misleads a veteran in 2026.
The Threshold VA Actually Uses
The Census Bureau publishes poverty thresholds annually in its official poverty report. In the most recently published table, the threshold for one unrelated individual under 65 years old is $16,320, and for one person 65 years and over it is $15,045. Note that these are Census thresholds, not the Department of Health and Human Services poverty guidelines used for Medicaid and similar programs. The two are different figures, and substituting one for the other is a common and costly error. Veterans should confirm the threshold for the year that applies to their claim.
What Counts as Earned Income
The regulation speaks to the veteran's earned annual income. That points to wages and self-employment earnings from the veteran's own labor, not a spouse's salary and not the household total. Because individual cases vary, the safe practice is to document gross earnings precisely, keep pay records for the full calendar year, and never guess at the total on a VA form.
Protected Environments and the Facts-Found Exception
Here is the trap that surprises veterans most: earning above the poverty threshold does not automatically defeat a TDIU claim, and earning below it does not automatically win one. The same paragraph of 38 CFR 4.16(a) states that marginal employment "may also be held to exist, on a facts found basis (includes but is not limited to employment in a protected environment such as a family business or sheltered workshop), when earned annual income exceeds the poverty threshold." The regulation closes by directing that consideration shall be given in all claims to the nature of the employment and the reason for termination.
That is a strategic opening. A veteran working in a brother's warehouse who is permitted to leave when migraines strike, who is excused from the productivity standards applied to every other worker, and who would be terminated tomorrow in a competitive workplace may be in marginal employment even at a wage above the threshold. The question is whether the job exists in a competitive environment or only because an accommodation shelters it.
Documenting a Sheltered or Accommodated Job
Assertion is not evidence. A protected-environment argument is built from records: a written statement from the employer describing the specific accommodations granted, attendance records showing missed days, documentation of reduced quotas or duties compared with other employees, and a description of who absorbs the work the veteran cannot complete. Lay statements from coworkers and supervisors carry weight when they describe observable facts rather than opinions about disability. The stronger the paper trail, the less the decision depends on a rater's assumptions about what the wage figure means.
How to Apply While Still Working Part Time
The fear of filing while employed stops many eligible veterans cold. The application itself asks directly about work, so accuracy matters more than optimism. Five steps organize the process.
- Confirm the percentage gates under 38 CFR 4.16(a), or prepare an extra-schedular argument under 4.16(b) if those gates are not met.
- Gather the full employment record for the last five years: employers, dates, hours, gross earnings, time lost to illness, and the reason each job ended.
- Complete VA Form 21-8940, the Veteran's Application for Increased Compensation Based on Unemployability, which can be submitted online at VA.gov instead of on paper.
- Collect medical evidence tying the inability to work to service-connected conditions specifically, and not to age, nonservice-connected illness, or a layoff.
- Submit and track the claim, and respond promptly to every VA development letter, because unanswered requests slow decisions.
VA Form 21-8940 in Practice
This form asks for the highest gross monthly earnings, the dates of employment, time lost from illness, and education and training history. Understating income invites a later overpayment finding; overstating hours invites a denial. Report what payroll records show. Where employment was accommodated, say so plainly on the form and attach the supporting statements rather than relying on the rater to infer it.
VA Form 21-4192 and the Employer's Role
VA Form 21-4192 is the Request for Employment Information in Connection with Claim for Disability Benefits. It is the employer's form, not the veteran's. After a 21-8940 is filed, VA sends it to employers listed for the last year of employment to confirm dates, earnings, concessions made, and the reason employment ended. Veterans who alert former employers in advance often see faster and more complete responses.
After Filing: Exams, Decisions, and Keeping TDIU
Approval is not the end of the anxiety. Many veterans granted TDIU then refuse every job offer for fear of triggering a reduction. The regulations are more protective than that reputation suggests, and knowing them restores real choices.
The 12-Month Rule
Under 38 CFR 3.343(c)(2), if a veteran with TDIU begins to engage in a substantially gainful occupation after January 1, 1985, the rating may not be reduced solely on the basis of having secured and followed that occupation unless the veteran maintains it for 12 consecutive months. The regulation adds that temporary interruptions of short duration are not breaks in otherwise continuous employment. A trial return to work that fails within a year is therefore not, by itself, grounds for reduction.
The Evidence Standard for Reduction
Section 3.343(c)(1) requires that in reducing a TDIU rating, caution must be exercised so that actual employability is established by clear and convincing evidence, with the due-process procedures of 38 CFR 3.105(e) applied. The same section protects veterans in vocational rehabilitation, education, or training, and states that participation in — or pay received from — a therapeutic or rehabilitation activity under 38 U.S.C. 1718 shall not be considered evidence of employability. Expect a C&P examination during the claim and possible future reexaminations, and keep earnings records current throughout.

Frequently Asked Questions
Does earning one dollar over the poverty threshold automatically end TDIU?
No. The threshold is the general rule for marginal employment, not an automatic bar. Under 38 CFR 4.16(a), marginal employment may also be found on a facts-found basis when earned income exceeds the poverty threshold, including employment in a protected environment such as a family business or sheltered workshop. The regulation also directs that the nature of the employment and the reason for termination be considered in all claims. Crossing the line does mean the claim will be examined more closely, and the veteran carries the burden of showing the job is not competitive employment. Documentation of accommodations, missed time, and reduced duties is what makes that showing possible.
What does TDIU pay compared with a schedular 100 percent rating?
TDIU pays at the same monthly rate as a 100 percent schedular rating. For 2026, following the 2.8 percent cost-of-living adjustment effective December 1, 2025, the published rate for a veteran alone at the 100 percent level is $3,938.58 per month, with higher amounts for veterans with dependents. Rates change each December with the COLA, so the current table on VA.gov is the only reliable source. Note that TDIU and a schedular 100 percent rating are not identical in every respect; eligibility for certain ancillary benefits can differ, and permanence is a separate determination from the total rating itself.
Is household income counted, or only the veteran's earnings?
The regulation refers to the veteran's earned annual income. A spouse's wages are not the veteran's earned income, and the marginal-employment test is written around the poverty threshold for one person rather than a family of any size. That said, VA forms ask specific questions and should be answered exactly as asked. Veterans should report their own gross earnings accurately, retain pay stubs and tax records for the full year, and avoid estimating. Where a veteran is self-employed, net earnings and the hours actually worked both matter, because a business that runs on a spouse's or partner's labor is a different picture than one the veteran operates alone.
Can a veteran apply for TDIU while currently employed?
Yes. Employment does not bar an application, and the application form asks for current and recent work history precisely because VA expects to evaluate it. What defeats a claim is substantially gainful employment, not any employment at all. A veteran working reduced hours in an accommodated position can file, describe the accommodations, and submit employer statements supporting the description. Filing while working also protects the effective date, which is often lost when veterans wait until they stop working entirely. Report the hours and earnings that payroll records show, and let the evidence establish whether the work is marginal.
What happens if a trial return to work does not last?
38 CFR 3.343(c)(2) addresses this directly. If a veteran with TDIU begins a substantially gainful occupation after January 1, 1985, the rating may not be reduced solely because the veteran secured and followed that occupation unless it is maintained for 12 consecutive months. Temporary interruptions of short duration do not count as breaks in continuous employment. A job attempted and lost inside that window because service-connected symptoms made it unsustainable is generally treated as a failed work attempt rather than proof of employability. Veterans should document why the job ended, keep separation paperwork, and notify VA of income changes rather than waiting to be asked.
Which form starts a TDIU claim, and what does the employer file?
The veteran files VA Form 21-8940, the Veteran's Application for Increased Compensation Based on Unemployability, available on VA.gov and completable online. The employer's form is VA Form 21-4192, the Request for Employment Information in Connection with Claim for Disability Benefits. VA sends 21-4192 to the employers listed for the last year of employment to verify dates, earnings, any concessions made because of disability, and the reason employment ended. The veteran does not complete 21-4192. Delays are common when former employers ignore the request, so giving them advance notice and a point of contact is a practical step that keeps a claim moving.
What if the percentage requirements are not met at all?
Extra-schedular consideration remains available. Under 38 CFR 4.16(b), it is established VA policy that all veterans unable to secure and follow a substantially gainful occupation because of service-connected disabilities shall be rated totally disabled, and rating boards are directed to refer such cases to the Director, Compensation Service, when the percentage standards in paragraph (a) are not met. The referral package must include a full statement of the service-connected disabilities, employment history, educational and vocational attainment, and all other factors bearing on the issue. These claims are harder and depend heavily on vocational evidence, medical opinions addressing functional limitations, and a well-documented work history.
