Form HA-4631: Updating Past Work History for Hearing

Form HA-4631, titled Claimant's Work Background, is the administrative questionnaire you submit before an Administrative Law Judge (ALJ) hearing to update your employment history and physical job demands. Providing an accurate accounting of your past duties ensures that the vocational expert classifies your work correctly under 20 CFR 404.1560 and prevents improper denials at Step 4 of the sequential evaluation process.

When your disability claim transitions to the Office of Hearings Operations (OHO), your initial work history report may be outdated. The hearing office issues Form HA-4631 to capture accurate details about job titles, daily physical activities, supervisory responsibilities, and machine operation. Completing this form with precision protects your appeal from misunderstandings regarding your vocational capabilities.

Purpose of Form HA-4631 at the Hearing Level

During the administrative hearing, the ALJ must determine whether your medical conditions prevent you from performing any of your past relevant work. Under 20 CFR 404.1520(f), this inquiry takes place at Step 4 of the sequential disability evaluation process.

To make this determination, the judge calls an independent vocational expert to testify about the skill levels and exertional demands of your previous employment. The vocational expert relies directly on your written descriptions in Form HA-4631 to match your jobs with classifications in the Dictionary of Occupational Titles (DOT). If your descriptions are inaccurate, the vocational expert may misclassify your work as lighter or simpler than it actually was.

Under Social Security Ruling 82-62, a claimant's past work must be documented thoroughly regarding physical exertion, technical skill, and cognitive demands. Form HA-4631 serves as your sworn statement describing how you actually performed your jobs on a daily basis.

The Five-Year Relevant Work Rule in 2026

Prior administrative rules required disability claimants to report fifteen years of detailed employment history. However, the Social Security Administration modernized 20 CFR 404.1565 to reduce the past relevant work lookback period from fifteen years down to five years.

In 2026, under 20 CFR 404.1565(b), adjudicators consider work you performed within the five years prior to your alleged onset date or date last insured. Work performed older than five years is generally excluded from past relevant work consideration unless special circumstances apply.

This regulatory change reduces the documentation burden on Form HA-4631. You only need to focus on jobs held during this five-year window. Furthermore, narrowing the scope prevents the SSA from denying your claim based on specialized skills acquired at a job you have not performed in over a decade.

Substantial Gainful Activity Thresholds

Not every job you held in the past five years qualifies as past relevant work. Under 20 CFR 404.1574, employment only counts as past relevant work if it constituted substantial gainful activity (SGA) and lasted long enough for you to learn the job.

In 2026, the monthly substantial gainful activity earnings threshold for non-blind individuals is $1,620 per month. If you worked a brief part-time position where your monthly earnings remained below $1,620 in 2026, that job does not qualify as substantial gainful activity under SSA guidelines.

When filling out Form HA-4631, clarify your exact monthly or weekly earnings for each position. If a job was a brief trial that lasted only a few weeks, note that it was an unsuccessful work attempt under 20 CFR 404.1574(c). Demonstrating that a short-lived position was not substantial gainful activity prevents the vocational expert from treating it as a viable past occupation.

Documenting Physical Demands and Exertion Levels

The core of Form HA-4631 is the section detailing the physical activities required by each position. Under 20 CFR 404.1567, the SSA categorizes work into five exertional categories: sedentary, light, medium, heavy, and very heavy.

You must provide specific hourly breakdowns for the following physical functions:

• Sitting: Record how many total hours you sat during an average workday.
• Standing and Walking: Indicate the total hours spent on your feet, including pacing, inspecting, or patrolling.
• Lifting and Carrying: Identify the heaviest object you lifted and the weight you lifted frequently throughout the day.
• Postural Actions: Detail how often you had to bend, crouch, kneel, crawl, or climb stairs.
• Reaching and Handling: Note whether your duties required reaching overhead, typing, operating hand controls, or grasping tools.

Accurate weight figures are critical. For example, under 20 CFR 404.1567(b), light work requires lifting no more than twenty pounds at a time with frequent lifting of up to ten pounds. If your job title was cashier, but your employer required you to lift forty-pound boxes of stock every morning, your job was performed at the medium exertional level. Explaining this difference prevents the vocational expert from assuming you worked at a light exertion level.

Explaining Supervisory and Technical Duties

Skill levels are classified under 20 CFR 404.1568 into unskilled, semi-skilled, and skilled occupations. The vocational expert evaluates your specific vocational preparation (SVP) based on the training time required for each role.

On Form HA-4631, describe your actual responsibilities rather than administrative job titles. If your title was lead clerk, but you did not have the authority to hire, fire, schedule, or discipline employees, clarify that your duties were entirely routine. Inaccurate statements suggesting managerial authority can lead the vocational expert to conclude that you have transferable management skills under 20 CFR 404.1568(d).

Similarly, explain whether you used complex technical software, handled sensitive financial accounts, or performed routine data entry. Precise explanations prevent the ALJ from finding that you possess advanced intellectual skills that could transfer to sedentary desk jobs.

Identifying Composite Jobs Under POMS DI 25005.020

Many modern jobs do not fit neatly into a single occupational description found in the Dictionary of Occupational Titles. Under Program Operations Manual System (POMS) DI 25005.020, a composite job is an occupation that combines significant elements of two or more distinct jobs.

For instance, you may have worked as a delivery driver who also spent half of each shift performing heavy warehouse restocking. Under POMS DI 25005.020, an ALJ cannot find you capable of performing past relevant work at Step 4 unless you can perform all components of a composite job.

If you performed multiple roles under a single job title, use Form HA-4631 to detail the time spent on each task. Clearly separating the clerical duties from the physical warehouse tasks helps your representative establish that the position was a composite job.

Deadlines and the Five-Day Evidence Rule

Submitting Form HA-4631 is subject to the strict administrative deadlines governing ALJ hearings. Under 20 CFR 404.935, you must submit all written evidence at least five business days before the date of your scheduled hearing.

In 2026, hearing offices require timely submission of work history updates so that the vocational expert can review the exhibits before taking the stand. If you submit the form on the morning of the hearing, the judge may delay the proceeding or refuse to accept the document under 20 CFR 404.935(b).

You or your appointed representative should review the completed Form HA-4631 against your certified earnings record in Section D of the hearing exhibits. Submitting the form well in advance ensures that the vocational expert has the correct occupational profile when forming opinions.

Step-by-Step Instructions for Completing Form HA-4631

Completing Form HA-4631 carefully ensures that your vocational testimony will be consistent with your written record. Following an organized method prevents omissions.

Follow these practical steps:

First, pull your certified Social Security earnings statement to verify your employers and dates of service for the five years prior to your disability onset date.

Second, write down each job title you held during that five-year period. Do not embellish your title or use an internal company acronym that a judge will not understand.

Third, describe your daily physical routine from the start of your shift to the end. Estimate the hours spent standing, walking, and sitting, ensuring the total matches your scheduled shift length.

Fourth, specify the exact weights of tools, equipment, or products you were required to lift and carry. If you lifted boxes weighing thirty pounds multiple times an hour, state that clearly.

Fifth, describe any machines, tools, or computer systems you operated. Clarify whether you followed standard instructions or had independent decision-making authority.

Sixth, double-check that your answers align with any past work descriptions you submitted at the initial application stage. Consistency between documents reinforces your overall credibility under SSR 16-3p.

Common Mistakes That Lead to Step 4 Denials

Many avoidable mistakes on Form HA-4631 can negatively affect the outcome of an administrative hearing. Being vigilant helps safeguard your claim.

A frequent error is overstating physical independence. Claimants often write that they lifted fifty pounds because that was in the official job description, even though they routinely received help from coworkers or were accommodated by a supervisor. If you received accommodations or special assistance, you must state that on the form under 20 CFR 404.1573(c).

Another common pitfall is omitting brief jobs that were physically demanding. If you attempted a heavy labor job that lasted only three weeks before your medical condition forced you to stop, listing it as an unsuccessful work attempt provides proof of your worsening physical limitations.

Finally, avoid vague generalities like various warehouse duties. Provide concrete facts, such as unloaded pallet trucks using manual hand jacks and carried forty-pound crates. Specific facts enable the vocational expert to assign an accurate DOT code.
