Past Relevant Work After SSA’s Five-Year Rule: What Changed and How It Affects Steps Four and Five

The rule shrank the work history that steps four and five are built on. For many claimants that is good news. For representatives it means the old fifteen-year work history form is no longer the map — and a VE who classifies work outside the window, or misses a job inside it, is testifying about the wrong history.

The three tests — plus the 30-day rule

A job is past relevant work only if all of these are true (20 CFR 404.1560(b)(1)):

1. Recency — it was done within the past five years.
2. Substantial gainful activity — it rose to the SGA level.
3. Duration to learn — it lasted long enough for the claimant to learn to do it.
4. Not a short job — it did not start and stop in fewer than 30 calendar days.

The 30-day rule is measured strictly. Thirty calendar days means 30 consecutive days, including weekends, from the first day of work. SSA generally does not consider total hours or days worked in that period, or whether the job was full-time or part-time. For self-employed people and independent contractors, SSA looks at whether they did the same type of work for 30 calendar days, even if individual assignments were shorter (20 CFR 404.1560(b)(1)(ii)). The 30-day requirement is separate from SGA and from the time needed to learn the job.

Where does the five-year window start and end?

SSA considers work experience to apply when it was done within the last five years, and does not usually consider work done more than five years “before the time we are deciding whether you are disabled (or when the disability insured status requirement was last met, if earlier)” (20 CFR 404.1565(a)). In a Title II claim with an expired date last insured, count back from the DLI, not from the hearing date. Get this wrong and the VE may classify jobs that should never have been in the analysis.

Why it matters at step four

At step four, SSA compares the RFC with the physical and mental demands of past relevant work, either as the claimant actually performed it or as generally performed in the national economy (20 CFR 404.1560(b)(2)). If the claimant can still do past relevant work, SSA finds them not disabled without considering age, education, and work experience (20 CFR 404.1560(b)(3)). Fewer jobs in the window means fewer ways to end the case at step four.

Why it matters at step five

Work experience as a vocational factor follows the same five-year logic. If the claimant has no work experience, or only work that started and stopped in fewer than 30 calendar days during the five-year period, SSA generally considers that it does not apply (20 CFR 404.1565(a)). Skills from older jobs drop out of the transferability analysis — which can change which Medical-Vocational Guidelines rule applies for claimants age 50 and older.

A representative’s checklist

• Fix the end date first — decision date or date last insured, whichever is earlier.
• Rebuild the work history from the earnings record, not from memory — start and stop dates for every employer inside the window.
• Screen each job against SGA, time to learn, and the 30-calendar-day rule.
• Document how the job was actually performed — lifting, standing, walking, tools, and mental demands — so the VE classifies the real job.
• Challenge classification at the hearing. Under SSR 24-3p, SSA expects representatives to raise questions about VE testimony at the time of the hearing.

How Precision Case Lens helps

Precision Case Lens is SSA disability case development software built by a Social Security Vocational Expert with 30 years in the witness chair. Its hearing deliverables include vocational analysis of the claimant’s work history against the DOT, SVP levels, and the Medical-Vocational Guidelines, with every finding cited to the exhibit and page.
