A veteran on r/VeteransBenefits this week could not tell whether the 100% on his award letter was TDIU or a schedular rating, and was afraid to drive for Uber. The top answer, with 80 upvotes: you are being confused by a glossary. That is the whole problem. Two groups of veterans are paid the same $3,938.58 a month, one of them has no earnings rule at all, and the other has a rule that is far more protective than the "12 months and it's gone" version that circulates. Here is how to tell which one you hold, what the regulation actually says, the dollar line it actually points to, and the month a GS paycheck could first change your check.

What the Glossary Says vs. What the Regulation Says

What people believe What the regulation says Where
"100% P&T means I can't work" A 100% schedular rating has no earnings rule. 38 CFR 4.16 applies only "where the schedular rating is less than total." 38 CFR 4.16(a)
"TDIU and 100% are the same thing" TDIU is paid at the 100% rate on a combined schedular rating below 100%, often 70%. Your letter says which one you hold. 38 CFR 4.16(a)
"The TDIU income cap is $15,960" The regulation names the Census Bureau poverty threshold for one person: $16,330 for 2025 income, $16,749 if under 65. $15,960 is the 2026 HHS guideline. 38 CFR 4.16(a); Census P60-290, table 10
"After 12 months of work VA ends TDIU" VA may not reduce solely for the job until you have held it 12 consecutive months, and a proposal plus two 60-day notice periods precede any change. 38 CFR 3.343(c)(2); 3.105(e)
"Any job over the line ends TDIU" Work in a protected environment (family business, sheltered workshop) can be marginal even above the threshold. 38 CFR 4.16(a)
"Losing TDIU costs me veterans' preference" Preference and the 30% hiring authority key off the compensable schedular rating, which the job does not reduce. 5 U.S.C. 3112; 5 CFR 316.302

The table summarizes the cited regulations, statutes and Census data (eCFR 2026-01-01 edition; Census P60-290).

Frequently Asked Questions

How do I tell whether I have TDIU or 100% schedular P&T?

Your VA benefits letter, not the glossary on the VA website. A TDIU award is paid at the 100% rate while your combined schedular rating stays lower, often 70%. A 100% schedular rating is 100% on the schedule itself. Look for the words individual unemployability and permanent and total. The distinction decides whether the earnings rule applies to you at all.

I have 100% schedular P&T. Is there an income limit?

No VA earnings rule applies to you. 38 CFR 4.16, the regulation that contains the marginal-employment line, opens with the words where the schedular rating is less than total. A total schedular rating is outside it by the regulation's own terms.

What is the TDIU income limit?

For income earned in 2025 it is $16,330, the Census Bureau's weighted-average poverty threshold for one person, which is the figure 38 CFR 4.16(a) names. If you are under 65 the line is $16,749. The $15,960 you have seen quoted is the 2026 HHS poverty guideline, a different document, and it runs $370 to $789 lower than the number the regulation points to. There is no 2026-income-year threshold yet.

If I take a GS job on TDIU, when does my VA check actually change?

In the normal sequence, not for about 17 months. VA cannot reduce a TDIU rating solely because you took a substantially gainful job unless you hold it 12 consecutive months (38 CFR 3.343(c)(2)). A proposed reduction then opens a 60-day evidence window; after the final rating decision a second 60-day period runs, and the reduction takes effect the last day of the month that period ends (38 CFR 3.105(e)). The regulation sets those protections and notice periods, not a guaranteed calendar date.

Can I do anything to keep my payments while VA decides?

Yes, and the deadline is short. Request a predetermination hearing within 30 days of the proposal notice and your benefits continue at the previously established level pending a final determination (38 CFR 3.105(i)). The 60-day evidence window and the 30-day hearing window are different clocks.

Does losing TDIU cost me veterans' preference or the 30% disabled-veteran hiring authority?

No. The 30%-or-more noncompetitive authority (5 U.S.C. 3112; 5 CFR 316.302) and the conversion route (5 CFR 315.707) key off your compensable schedular rating, which the job does not reduce. A TDIU veteran with a 70% combined rating clears the 30% bar regardless.

Does a family business or sheltered workshop count differently?

Yes. 38 CFR 4.16(a) lets VA find marginal employment on a facts-found basis for work in a protected environment such as a family business or sheltered workshop, even when earnings exceed the poverty threshold. A competitive GS appointment is the opposite case.

How much is a GS job actually worth if it ends my TDIU?

Run it as a difference, not a total. You keep your schedular rating; you lose only the gap up to the 100% rate, and that gap is tax-free. At a 70% schedular rating the gap is $25,561.56 a year, so the breakeven gross salary lands near $36,500 at a 30% effective rate. GS-7 step 1 is $50,460 at Rest of U.S. and $53,361 in Atlanta, so the breakeven is cleared at the lowest-paid locality at the entry grade, before FERS, the TSP match, or FEHB.

First, Read Your Letter: Which 100% Do You Hold?

Total disability based on individual unemployability pays the 100% compensation rate to a veteran whose combined schedular rating is lower, typically 60% for a single condition or 70% combined with one condition at 40%, when service-connected disabilities make it impossible to "secure or follow a substantially gainful occupation." A 100% schedular rating is different: the rating schedule itself adds up to 100%. Both letters can say "100%." Only one of them carries an earnings rule.

The regulation makes the split explicit in its first clause. 38 CFR 4.16(a) begins: "where the schedular rating is less than total." A veteran rated 100% by schedular evaluation is outside that regulation entirely: there is no earnings ceiling, and income by itself cannot reduce the rating. Work can still be evidence of improvement in a properly supported rating review under 38 CFR 3.343(a), which looks at how the disability behaves under ordinary conditions of life, including work. Permanent and total means no future routine exams are scheduled; it is not a work restriction. VA may still order an exam when it needs to verify a disability (38 CFR 3.327(a)), but a paycheck is not the trigger.

If your letter says individual unemployability, keep reading. If it says 100% schedular, the rest of this page is about your preference rights and the breakeven table, not about your check.

The Income Line Is $16,330, Not $15,960

Marginal employment, the kind that does not count against TDIU, is defined in 38 CFR 4.16(a) as earned annual income that does not exceed "the poverty threshold for one person" as established by the U.S. Census Bureau. That is a specific document: the Census Bureau's annual poverty thresholds table. For income year 2025 the weighted-average threshold for one person is $16,330, and for a person under 65 it is $16,749.

The figure that circulates on Reddit and in law-firm blogs is $15,960. That is the 2026 HHS poverty guideline for one person (91 FR 1797), a simplified version HHS publishes for program administration. HHS's own notice describes the guidelines as roughly equal to the Census thresholds, and the gap depends on your age: the under-65 threshold is $789 higher, the 65-and-over threshold $520 lower, and the weighted average $370 higher. A veteran under 65 who sizes part-time work to $15,960 is leaving up to $789 of protected marginal earnings unused. There is no 2026-income-year threshold yet; Census publishes them the following September.

Two more features of the rule matter. It is "one person" no matter how many dependents you support. And VA may find employment marginal on a facts-found basis even above the threshold when the work is in a protected environment such as a family business or sheltered workshop; a competitive GS appointment is the opposite case, and the regulation directs VA to consider the nature of the employment and the reason for any termination.

The 12-Month Protection and the Notice Clock: What a GS Job Actually Triggers

Competitors publish the 12-month rule as the endpoint. It is the beginning. Chain the regulations and, when VA lets the 12 months run before proposing, the earliest a dollar changes is the end of month 17. The regulation guarantees the 12-month protection and the two notice periods; the calendar arithmetic below is the normal sequence, not a promise.

  1. Months 1 through 12: no reduction is permissible on the basis of the job. 38 CFR 3.343(c)(2) bars a reduction "unless the veteran maintains the occupation for a period of 12 consecutive months." The word consecutive is in the regulation, but the same paragraph says temporary interruptions of short duration do not count as breaks in otherwise continuous employment. A short gap does not restart the clock; a real break does.
  2. Proposal: VA issues a proposed reduction under 38 CFR 3.105(e). The regulation does not bar an earlier proposal, but the reduction itself cannot rest solely on a job held less than 12 consecutive months, and nothing puts VA on a deadline for this step.
  3. Months 13 through 15: a 60-day window to submit evidence after the notice of the proposed action. Request a predetermination hearing within 30 days of that notice and payments continue at the old level until the final determination (38 CFR 3.105(i)).
  4. Month 15: the final rating action.
  5. Months 15 through 17: a second 60-day period from the notice of the final rating action. The reduction takes effect "the last day of the month in which a 60-day period from the date of notice to the beneficiary of the final rating action expires."

At the 2026 rate of $3,938.58 a month, 17 months of the 100% rate is $66,955.86 of tax-free compensation paid after the job starts in that sequence, before a single dollar changes. A hearing request extends it.

The shield is narrow in one respect: 3.343(c)(2) blocks a reduction based solely on the occupation. It does not block a reduction grounded in material improvement in the underlying condition, which follows its own rules under 38 CFR 3.344. VA also does not wait for you to report the job; SSA wage records reach VA, and the employment questionnaire, VA Form 21-4140, is still in use in its August 2024 revision.

The Breakeven: What a GS-7 Is Worth Against a Lost TDIU

Run the decision as a difference. When TDIU ends you drop to the combined schedular rating, which the job's earnings alone do not change. What you lose is the gap between that rating's rate and the 100% rate, and the gap is tax-free, so the salary has to clear it after tax.

Schedular rating under the TDIU Annual VA comp after reduction Tax-free income lost Breakeven gross salary at 25% at 30% at 35%
90% ($2,362.30/mo) $28,347.60 $18,915.36 $25,220 $27,022 $29,101
70% ($1,808.45/mo) $21,701.40 $25,561.56 $34,082 $36,517 $39,325
60% ($1,435.02/mo) $17,220.24 $30,042.72 $40,057 $42,918 $46,220

FedTools 2026 analysis. VA rates are the veteran-alone amounts effective December 1, 2025 (100% = $3,938.58/mo, $47,262.96/yr). Breakeven = tax-free income lost ÷ (1 − effective rate on the incremental salary); the 25/30/35% band is the combined federal marginal, FICA, and state burden on the added salary, an estimate, not an average tax rate.

GS-7 step 1 pays $50,460 at Rest of U.S. locality (17.06%) and $53,361 in Atlanta (23.79%) on the 2026 tables. Even the harshest cell, $46,220, is cleared by the lowest-paid locality at the entry grade by $4,240, before counting the FERS accrual, the TSP match, or FEHB.

Put the three paths side by side for a single veteran with a 70% combined rating, taking a GS-7 step 1 in Atlanta:

100% schedular P&T + GS-7/1 TDIU + GS-7/1 TDIU, no job
VA compensation, months 1 through 12 (tax-free) $47,262.96 $47,262.96 $47,262.96
GS salary (Atlanta) $53,361 $53,361 $0
Year-one total cash $100,623.96 $100,623.96 $47,262.96
Earliest month VA comp can change not on earnings alone (a supported medical review remains possible) after 12 months plus the notice periods (about month 17 as an illustration, not a guaranteed minimum) not applicable
VA comp after reduction $47,262.96 (unchanged) $21,701.40 (70%) $47,262.96
Steady-state annual cash $100,623.96 $75,062.40 $47,262.96
Steady state after 30% tax on the salary $84,615.66 $59,054.10 $47,262.96

FedTools 2026 analysis from the VA compensation rates and the 2026 GS tables. GS figures are before FERS, TSP and FEHB, which all favor the working columns.

The identification question decides the middle column. A schedular 100% keeps the left column unless a properly supported rating review finds improvement. A TDIU veteran keeps it through the 12-month protection and the notice periods (about 17 months in the illustration) and then lands at $75,062 a year, which is still $27,800 more than not working.

What the Job Does Not Touch

Losing TDIU does not touch your veterans' preference or the hiring authority you probably used. 5 U.S.C. 2108(2)'s definition of disabled veteran contains no percentage. The 30%-or-more noncompetitive appointment (5 U.S.C. 3112, 5 CFR 316.302) and the conversion to career-conditional status (5 CFR 315.707) key off your compensable schedular rating, which a paycheck does not reduce. A TDIU veteran with a 70% underlying rating clears the 30% bar whether or not TDIU survives. Run your points through the Veterans' Preference Calculator if you are still deciding whether to apply.

Two rules people conflate: 38 CFR 3.957 protects service connection that has been in effect ten years from severance (except for fraud, or a lack of qualifying service or character of discharge), and 3.951(b) protects an evaluation in effect twenty years from reduction below that level (except for fraud). Whether the twenty-year rule shields a TDIU total against a work-based reduction is a question we could not settle from the retrievable text, so we do not answer it here. The VA rating-reduction rights guide walks through the five reduction rules in detail.

Calculate the Salary Side

The breakeven above uses two federal pay inputs you can set for yourself: grade and step, and locality. The free GS Pay Calculator gives the gross salary from those three dropdowns, and the Military-to-GS Pay Translator maps a rank to a likely grade band for a first federal application. The Federal Take-Home Pay Calculator estimates the net on a GS salary by grade, step and locality; it does not model tax-free VA compensation, so add that back by hand.
