Verified CPA contact data
The CPA email list. 142,576 US firms, sorted by tier before a rep touches it.
Updated June 8, 2026
Most US accounting firms are sole practitioners who pick the software themselves. Enterprise databases barely have them. We find the partner, tier the firm, and tag the tax stack.
are firms with under 20 staff
The vast majority of US accounting firms are local practices, not regional brands. That is where the seat count and the budget actually sits.
are sole practitioners or two-partner shops
A single CPA, sometimes a partner and a bookkeeper. The decision-maker answers the phone, and they pick the software.
have no marketing or BD function
No CMO, no growth lead, no inbound channel for a vendor pitch. You reach them directly or you do not reach them.

Custom agent signals
The part a static CPA list cannot give you.
Tax software in use, busy-season hiring, audit-versus-tax mix. The signals a CPA practice broadcasts are not the ones a generic list captures. Point Orbital’s agents at your ICP and they research each firm for the signals you score on, then tag the record. A few that teams ask for:
If you can define the signal, an agent can go find it. That is the difference between a list and a worklist.
Coverage
Every specialization, all 50 states.
The list spans the full US population of CPA and accounting firms. The largest state economies carry the most depth. Selling into adjacent professional services too? See the attorney email list or browse the full /data directory.

How it is built
Built from the firm, not the license file.
Every firm in the US
Start from the full population of US CPA and accounting firms, rolled to firm grain, not stacked rows from a state license roll.
Tiered by firm size
Every firm is assigned to one of four tiers — Big 4, regional, mid-market, or local — so a rep knows the motion before they pull the record.
The partner, not the front desk
We find the managing partner or decision-maker for each firm, with role and seniority, so a rep reaches the buyer who actually picks the software.
Validated before delivery
Emails are validated by our data source. Anything that fails is dropped, not counted. We hand you a smaller list that lands.
Tagged by signal
Agents tag the custom signals you score on — tax software in use, audit-versus-tax mix, PCAOB status — so the list arrives sorted by fit.
Put it to work
One list, several motions.
Accounting software
Reach partners choosing tax-prep, audit, or practice-management tools, segmented by firm-size tier.
Payroll & benefits
Sell payroll, HR, and benefits platforms to firms that run their own books and their clients' books.
Banking & lending
SMB banking, lines of credit, and embedded-finance offers aimed at firm owners and their client base.
M&A and recruiting
Source firms for roll-ups and recruit partners and senior staff during the busy-season hiring window.
CE & credentialing
Reach practicing CPAs with continuing-education courses they need to keep their license current.
Insurance & compliance
E&O and cyber insurance, SOC reporting tools, and PCAOB-adjacent services for audit firms.
The long version
Detail, on demand.
Most B2B databases are built from a digital footprint: a company page, a careers site, ad spend, a marketing org chart. The Big 4 and the next hundred regional firms have all of that, so enterprise tools render them in full. Below that, the data gets thin fast.
The problem is that the US accounting market is shaped exactly the opposite of how those tools were built. The vast majority of US CPA firms are local practices with a single-page website and no marketing staff. The decision-maker is the partner whose name is on the door. A LinkedIn-only database stops here.
We build this list from the bottom up. We start with the full firm population, tier it by size, and find the partner contact for each firm — including the ones a scraped-web database never surfaces. The result is a smaller number than a broker’s inflated quote, and a higher share of records that actually reach a decision-maker.
Selling audit software to a Big 4 partner is a different motion from selling a tax-prep workflow to a two-CPA practice in Toledo. The list ships pre-segmented so a rep is not qualifying their way out of the wrong tier.
| # | Tier | Firms (approx.) | Buyer / motion |
|---|---|---|---|
| 1 | Big 4 | 4 | Enterprise procurement, named-account selling — Deloitte, PwC, EY, KPMG |
| 2 | Regional & national | ~120 | Managing partner, IT director — RSM, BDO, Grant Thornton and peers |
| 3 | Mid-market | ~5,400 | Managing partner, owner — 5 to 50 staff, one or two offices |
| 4 | Local & sole | ~137,000 | Sole proprietor, founding partner — one to four people, the long tail |
Tier counts are approximate; the underlying record is exact. Orbital data, 2026.
Mapped. Start from the full US population of CPA and accounting firms, drawn from the 13,549,104-company small-business map, filtered to the accounting and CPA category set, and rolled to firm grain. A multi-office practice counts once, not once per location.
Tiered. Every firm is assigned a size tier using staff count, partner count, and entity-type signals. Tier counts are approximate because the cutoffs involve judgment; the underlying record is exact.
Matched. For each firm we identify the managing partner or decision-maker, with role and seniority, so a rep can tell a sole proprietor from a staff accountant before dialing.
Validated. Email addresses are validated by our data source before they reach you. Records that fail validation are dropped, not padded. We would rather hand you a smaller list that lands than a larger one that bounces.
Enriched. Agents tag the custom signals you score on — tax software in use, audit-versus-tax mix, PCAOB status — so the list arrives sorted by fit rather than zip code.
The honest disqualifier.
If your motion is purely Big 4 and the top 20 regional firms, you do not need a list this size. That TAM is small enough to map by hand, and a CRM enrichment tool will do the job without paying for the long tail you will never work.
This list is for teams selling into mid-market and local firms — the tiers where the seats are, where the software budget actually sits, and where enterprise databases run thin. If your quota is built on the Fortune 500’s accounting departments rather than independent CPA practices, this is not the right starting point.
What we do not fake: no stale CPA-license rolls, no scraped state-board dumps, no padded counts. If we cannot stand behind a field, it is not in the record.
Questions
Before you ask sales.
Can I get a free sample of the CPA list?
Yes. Tell us the firm-size tier and the states you care about and we send a sample of around 100 records so you can check the data against your own before anything changes hands.
How is the list segmented by firm size?
Four tiers, the way buyers actually sell. Big 4 (Deloitte, PwC, EY, KPMG), the next 120 or so regional and national firms, mid-market firms in the 5 to 50 staff range, and the local one-to-four-person practices that make up the long tail. Pick a tier and the list narrows to the buyer you can actually win.
What fields come with each contact?
Each record carries the contact (verified email, direct dial, LinkedIn), the person's role and seniority such as partner, managing partner, CFO, controller, or sole proprietor, and the firm itself: name, website, size tier, specialization, address, and years in business. Orbital's agents can also attach custom signals you define. We do not pad records with stale CPA-license rolls.
Can you tag tax-software signals?
Yes, and it is one of the most common asks. Point our agents at your ICP and they research each firm for which software they run — QuickBooks, Xero, Drake, Lacerte, ProSeries, CCH, UltraTax — and tag the record. Other common signals: busy-season hiring, PCAOB-registered, and audit-versus-tax mix.
Where does the data come from?
We start from the full population of US CPA and accounting firms in our 2026 canonical pull, attach partner and decision-maker contacts matched from professional profiles, and validate emails before delivery. The full count is a slice of Orbital’s 13,549,104-company US small-business map, filtered to the CPA and accounting category.
Do you cover sole practitioners?
Yes, and it is the part most brokers thin out on. Most US CPA firms are one-to-four-person practices, and the owner is the decision-maker. We hold them in the same record format as a regional firm — with the partner contact rather than a generic info inbox.
When should I not buy this list?
If your ICP is limited to Big 4 and the top 20 regional firms, you do not need a list this size. Your TAM is small enough to map by hand. This list is built for teams selling into the long tail of mid-market and local firms — the tiers that enterprise databases never had.
How is this different from ZoomInfo or a list broker?
Enterprise databases are built from digital footprints. Accounting firms below the top 100 run thin on company pages, careers sites, and ad spend, so coverage gets spotty fast below the regional tier. We map the full market from the firm up, including sole practitioners who never built a LinkedIn page, and add the tax-software and audit-mix signals a flat broker file will not carry. You get a scored account set, not a spreadsheet that bounces a third of the way down.

Tell us the firm-size tier and the states your reps cover. We will send a free sample of around 100 verified partner contacts to check against your own, no commitment. The accountant email list and attorney email list are built the same way.
