More about this list
Each row carries how many IRS-credentialed attorneys practice at that address: 13,290 are single-attorney practices, 1,217 have two, 512 have three, 699 have four to nine and 165 have ten or more. The segment worth the price is in the credentials column: 3,220 of these practitioners hold a law license and a CPA license at the same time. That is a specific, high-value prospect for anyone selling practice software, professional liability cover, CPE or succession services, and no compiled attorney list can isolate it, because holding two credentials at once is not a field a compiler records. Coverage is all 50 states plus DC, led by California 1,656, New York 1,420, Illinois 1,074, Florida 1,034 and Texas 982.

Using ChatGPT, Claude or an API?
No setup needed. Ask ChatGPT or Claude your question about the US Tax Attorneys & Tax Law Firms and give it this page: it can open https://locationlists.com/find?dataset=tax-attorney-list with the filters you need and show you the count and price.
Using ChatGPT or Claude? Tell it to answer from locationlists.com/find — no account, no connector.
How assistants ask
No connector needed. Any AI assistant can answer from this site with a web link, no connector, no account: open https://locationlists.com/find with the question as query parameters.
If a question needs filtering, distance, drive time, combining lists or a price, open a /find link: either put the question itself in q=, or build the structured link. The answer does not need an API, a connector or an account.
Simplest, the question itself: https://locationlists.com/find?q=<the question in plain words>
Or set the parts yourself: https://locationlists.com/find?dataset=<slug>&state=<ST>&city=<city>&county=<county>&zip=<zip>&near=<place or zip>&radius=<miles>&drive=<minutes>&where=<column>:<op>:<value>&total=<rows>
Leave out what the question does not need. Use radius for straight-line miles or drive for minutes of driving (5 to 60), not both; near can name several places separated by | to reach from any of them. To ask about several lists at once, use datasets with two or more names, or category with a kind of business. To compare two lists, add relate=nearest and the other list with b. in front of its parameters. To count by area, use areas=county (or zip, state, metro). To keep only places whose county, ZIP code, metro area or state meets a Census figure, add area_where (for example county:population>1000000); with areas, per=100000 gives counts per 100,000 residents.
Links an assistant can open, each showing how many rows match, a few preview rows and the price for just that part:

For developers
Every step below has a no-connector equivalent: https://locationlists.com/find?dataset=tax-attorney-list with the same filters as query parameters.
- Connect your agent to
https://locationlists.com/mcp(no key, no signup). - Call
count_locationswithdataset: "tax-attorney-list"and any filter — it is free, and returns how many rows match and what they cost. - Fetch the rows with
query_locations: $0.89 per 100 rows from this dataset. Above 7,865 rows, buying the whole file is cheaper.
Paid in USDC over x402 — the agent gets an HTTP 402 with the exact price, signs, and retries. Money moves only after rows are delivered, so a failed or empty query costs nothing. Setup for Claude, Cursor and VS Code
?Frequently Asked Questions
How many Tax Attorneys & Tax Law Firms are there in the US?
There are 15,729 Tax Attorneys & Tax Law Firms in the US as of September 2026. They are in all 50 states, DC and Puerto Rico. California has the most, with 1,635.
Is this a list of all US attorneys?
No. It is tax attorneys, and the name says so on purpose. There is no national registry of US attorneys at all — admission is granted state by state and the large bars actively prevent enumeration. California's own search form states that a location search returns "a random sample listing of attorneys"; New York's attorney search refuses non-browser requests outright. Anyone selling you a complete national attorney list compiled one from directories. This is built from a federal credential registry instead, which is narrower and verifiable.
What makes it a tax law firm?
At least one attorney at that address holds an IRS preparer credential, which the IRS verifies against the issuing bar. So it is not a firm that describes itself as doing tax work — it is a firm with a lawyer the IRS has confirmed is licensed and registered to prepare returns.
Are these firms or individual lawyers?
Firms. Every row is a practice at a business address and no individual's name reaches the file. Where an attorney reported no trading name, the row is dropped rather than published under their own name — 1,800 of them. We do not sell lists of licensed individuals.
How complete is it?
A tax attorney who prepares no returns holds no preparer credential and is absent, as is any firm where none of the lawyers do. There is no published universe of US tax law firms to measure against, so no honest completeness percentage exists. What can be said precisely is the source: 26,180 attorney-credentialed preparers in the IRS's February 2026 extract, collapsed to 15,729 firms at distinct business addresses.
Why is this smaller than a broker's attorney list?
Because it is a different thing. Ten of the seventy-one vendors we surveyed sell an attorney list, and theirs is every lawyer they could compile. This is the tax practice specifically, verified against a federal registry, with the attorney-CPA overlap flagged. If you want volume, buy theirs. If you want to mail tax practices and know the credential is real, buy this.
