The 10 Largest SSDI Representative Firms in America, Ranked by SSA Fees Paid

There is no public dataset that tells you how many Social Security Disability Insurance cases any given law firm handled last year. The Social Security Administration does not publish case counts by representative, and it never has.

What it does publish, quietly, in its FOIA reading room, is a spreadsheet listing the several hundred representative firms that received the most in direct fee payments. That file gives you names, addresses, and dollar amounts. It is not a case count. But because SSDI fees are formula-driven rather than negotiated, the dollar figure tracks volume closely enough to answer the question most people are actually asking when they ask which disability firms are the biggest.

Here is what that file shows.

The ranking

These are the ten registrants that collected the most in direct SSDI representative fees from the Social Security Administration in fiscal year 2024, ranked by the dollar amount SSA paid them.

Source: Social Security Administration, "FY2024 Top 500 Representative Firms by Fees," a FOIA proactive disclosure. Figures are direct representative fees SSA paid in fiscal year 2024. Names and locations are the registrant records in that file. Ranking by Axis Legal Leads.

Across all 500 firms on the list, SSA paid about 971 million dollars in direct representative fees in fiscal 2024. The ten firms above collected 238 million of that, just under a quarter of the whole list, and the top three alone collected 108 million. The drop-off is steep. The five hundredth firm on the list collected about 174 thousand dollars, against the leader's 42.8 million.

Two things stand out. The top of the list is led not by law firms but by large non-attorney representative companies, which are permitted to represent claimants before SSA and operate at national scale. And the concentration is real. A handful of operators earn a share of total fees that the long tail of regional firms never approaches.

What the numbers do and do not mean

Three caveats matter, and stating them up front is the difference between a study attorneys trust and one they dismiss.

Fees are a proxy, not a count. A firm that wins more cases at the hearing level, where backpay has accumulated for years, will collect more per case than a firm that wins quickly at the initial level. Two firms with identical fee totals can have quite different caseloads. Under the current rules a representative fee is the lesser of twenty five percent of past-due benefits or the statutory cap, which the Social Security Administration raised to 9,200 dollars effective November 30, 2024.

The same firm can appear more than once. Large practices register multiple entities with SSA, so a single national brand can occupy several lines in the file under slightly different legal names. Any honest ranking has to decide whether to consolidate those entities, and say which it did. The SSA file does not disclose corporate parents, so we have not merged any entities. Each line above is a separate registrant exactly as it appears in the file, which means a single national brand may hold more than one of the spots or sit just outside the ten.

Direct payment is not the whole picture. The file captures fees SSA paid directly to representatives out of past-due benefits. Fee petition arrangements, fees collected outside the direct payment system, and work on claims that never produced backpay do not show up cleanly.

Why a lead marketplace built this

Firm size in this practice area is usually discussed with anecdote and marketing copy. The public data exists, it is just inconvenient to assemble, so almost nobody does it. We assemble it because the shape of the market determines what a case is worth, and what a case is worth determines what an acquisition channel can support.

The pattern the file reveals is consistent year over year. A small number of national operations, several of which are not law firms at all but non-attorney representative companies, collect a disproportionate share of total fees. Below them sits a long tail of regional practices doing solid volume in one or two states. The gap between those two groups is almost entirely a marketing gap, not a lawyering gap.

Method

For anyone who wants to reproduce or challenge this:

1. Download the most recent "Top 500 Representative Firms by Fees" file from the SSA FOIA reading room. SSA publishes this as a proactive disclosure, so no FOIA request is required.
2. Normalize firm names. Strip suffixes, collapse punctuation variants, and manually review the top hundred rows for entities that share a parent.
3. Rank by total direct fees paid for the fiscal year.
4. Cross-check the national totals against the SSA representation statistics page, which reports aggregate fee volume and dollars. Your consolidated top ten should be a plausible fraction of that national total.
5. Optionally, add a federal court cut. Nature of suit codes 860, 863, and 864 identify Social Security appeals in federal district court, and CourtListener exposes counsel names, so you can tally which firms appear most often on appeal. This covers only the small slice of claims that reach federal court, so treat it as a second signal rather than a ranking.

If you find an error in our ranking, tell us and we will correct the table and say what changed.

The takeaway for firms outside the top ten

The firms on this list are not winning because they have a technique nobody else has. They are winning because they solved intake and acquisition at scale, and then kept the machine fed. Everything that separates a two million dollar disability practice from a twenty million dollar one happens before the case file opens.

That is the part we write about most often, and it is the part where a mid-sized firm can actually close the gap.
