Retrospective Vocational Opinions: Proving an Earlier TDIU Effective Date

Last reviewed: September 2026. This article explains how retrospective vocational opinions are used in VA claims. It is not legal advice; effective date questions are fact-specific, and an accredited representative should review your file.

Most vocational opinions answer a present-tense question: can this veteran secure and follow substantially gainful work now? A retrospective vocational opinion answers a past-tense one: when did the veteran's service-connected disabilities first prevent substantially gainful work? When VA grants TDIU but assigns a later effective date than the evidence supports, that question can be worth years of back pay.

This guide explains how TDIU effective dates work, what a retrospective opinion must rest on, the most common reasons these opinions get little weight, how the period should be scoped, and what an attorney should send.

Why the Effective Date Matters So Much

TDIU is paid at the 100% rate. For a veteran with no dependents, that is $3,938.58 per month as of December 1, 2025, compared with $1,808.45 at 70%. Each month the effective date moves earlier adds the difference between the veteran's schedular rate and the 100% rate for that period, subject to the rates in effect at the time. That is why effective date disputes are often worth more than the original grant, and why attorneys order retrospective opinions. See how TDIU back pay is calculated.

How TDIU Effective Dates Work

A few rules frame every retrospective case:

• TDIU is part of a rating claim. In Rice v. Shinseki, 22 Vet. App. 447 (2009), the court held that a request for TDIU is not a freestanding claim; it is part of an initial rating claim or a claim for increase when unemployability is raised by the veteran or the record. That means the TDIU effective date can reach back to the underlying claim if the evidence shows unemployability during that time.
• Increases can reach back up to a year before the claim. Under 38 CFR § 3.400(o)(2), the effective date for an increase in disability compensation is the earliest date it is factually ascertainable that an increase occurred, if a complete claim or intent to file is received within one year from that date; otherwise it is the date the claim was received.
• Continuous pursuit protects the original date. Under 38 CFR § 3.2500(h), when a claimant continuously pursues an issue by timely filing successive review options, the effective date is fixed from the date of the initial claim or the date entitlement arose, whichever is later.
• Entitlement must be shown for the period. Even with an early claim date, TDIU can only be paid from when the evidence shows the veteran met the requirements, including the rating thresholds in 38 CFR § 4.16(a) or an extraschedular basis under § 4.16(b).

The retrospective opinion speaks to the last point: the date the veteran's service-connected disabilities first prevented substantially gainful work, and whether that continued. For more on effective dates, see how to maximize your TDIU effective date.

What a Retrospective Vocational Opinion Is

A retrospective vocational opinion applies the same analysis as a current one, work history, transferable skills, and the labor market, to a defined period in the past. It asks what the veteran's documented service-connected limitations were during that period and whether, given the veteran's education, training, and work history at the time, any substantially gainful work remained.

Retrospective opinions are not unusual in VA law. The court held in Chotta v. Peake, 22 Vet. App. 80 (2008), that VA's duty to assist may require a retrospective medical opinion when the existing evidence is not enough to decide the rating for a past period. A private retrospective vocational opinion serves a similar purpose on the employability question.

The Evidence It Must Anchor To

A retrospective opinion is only as strong as the dated evidence behind it. The expert should cite records from the period, not rely on how the veteran is doing today. Useful sources include:

• Treatment records and C&P exams from the period, especially those describing functional limits, flare-ups, medication side effects, or hospitalizations
• Rating decisions showing when each service-connected condition was rated and at what level
• Employment records: dates of hire and separation, job duties, reasons for leaving, accommodations, discipline, and attendance
• VA Form 21-8940 and 21-4192 responses
• Earnings records such as W-2s, tax returns, or a Social Security earnings statement, which show year-by-year income for comparison with the Census poverty threshold for one person for each year
• Social Security disability records and decisions, which VA must consider when relevant (Murincsak v. Derwinski, 2 Vet. App. 363 (1992))
• Lay statements from the veteran, family, coworkers, or supervisors describing work problems during the period
• Vocational rehabilitation (VR&E) records, if the veteran applied or participated

Gaps in the record are common. A good retrospective opinion says where the record is thin and explains what it relied on instead, rather than filling gaps with assumptions. If a key period has no records at all, the representative may also consider asking VA for a retrospective medical opinion, as discussed in Chotta, so the vocational analysis has a medical foundation to build on.

Why Some Retrospective Opinions Get Little Weight

The court has said an opinion's value comes from its factual accuracy and sound reasoning (Nieves-Rodriguez v. Peake, 22 Vet. App. 295 (2008)). Retrospective opinions tend to be discounted for predictable reasons:

• The wrong period. The opinion addresses the veteran's current condition, or a period that does not match the one on appeal.
• No dated anchors. It states a date of onset without citing records from that time.
• Ignoring contrary evidence. It does not address work, earnings, or favorable exam findings during the period.
• Non-service-connected conditions or age. It relies on conditions VA cannot count, or on age, which 38 CFR § 4.19 bars.
• Speculative wording. Phrases like "may have been" or "possibly" without an explanation give the adjudicator little to rely on.
• Ratings not yet in place. It assumes a disability counted during a period before it was service connected or rated, without explaining how TDIU could apply then.

How the Period Should Be Scoped

Scoping is the most important step, and it should happen before any analysis begins. We ask the representative to define:

• The effective date assigned and the earlier date sought
• The date of the underlying claim or intent to file, and any earlier pending claims
• The rating history for each service-connected condition across the period
• Key events: the last date of full-time work, job changes, hospitalizations, and when new conditions were service connected

The opinion then states the period in plain terms, for example "from [date] through the present," and explains the evidence for each part of it. If the evidence supports a later date than the one sought, a credible expert says so. If the veteran worked during part of the period, the opinion addresses whether that work was marginal, year by year, or in a protected environment under 38 CFR § 4.16(a).

Attorney Intake Checklist

• The decision granting TDIU and the effective date assigned, plus any decision on appeal
• The claim and intent-to-file dates, and the procedural history
• Rating decisions for each service-connected condition
• Treatment records and C&P exams for the period at issue
• Employment and earnings records for the period
• Forms 21-8940 and 21-4192
• SSA records, if any
• Lay statements from the period

• Your deadline, including any Board evidence window

We then schedule a structured remote interview with the veteran, with questions focused on the period at issue. The standard assessment is a flat $1,599; retrospective cases with long periods or very large files may need a custom quote, which we confirm during the fit check. The report is delivered in 5–7 business days once we have both the records and the completed interview. See our attorney guide.

Frequently Asked Questions

What is a retrospective vocational opinion?

It is a vocational analysis of a past period. It explains when a veteran's service-connected disabilities first prevented substantially gainful work, based on records from that time.

Can TDIU be granted back to before I filed a TDIU form?

It can. Under Rice v. Shinseki, TDIU is part of the underlying rating claim, so the effective date can reach back to that claim if the evidence shows unemployability then.

What evidence does a retrospective opinion need?

Dated records from the period: treatment notes, exams, rating decisions, employment and earnings records, SSA records, and lay statements describing work problems at the time.

Why do some retrospective opinions get little weight?

Common reasons are addressing the wrong period, lacking dated evidence, ignoring contrary evidence, relying on non-service-connected conditions or age, and speculative wording.

How long does a retrospective report take?

Our standard report is delivered in 5–7 business days once we have both the records and the completed interview. Very large files may need a custom quote.

Our standard TDIU vocational assessment is a flat $1,599 (see pricing), and the written report is delivered in 5–7 business days once we have both your records and the completed interview. Not sure it fits your case? Request a free case fit check.
