Payroll for Law Firms: 8 Options Compared
Payroll for law firms compared on partner K-1 handling, trust account separation, and multi-state filing, plus what payroll does not cover at hiring.
Payroll for Law Firms Compared
Why partners never run through payroll, what trust account separation actually requires, and which of eight options fit a firm of five to fifty people
A law firm with fifteen people can be paying five different ways at once. Equity partners take draws against profit and receive a K-1. Associates get salary and a bonus on a W-2. A contract attorney invoices on a 1099. Paralegals are hourly with overtime. And somewhere in the background sits a trust account holding client money that must never come near any of it.
That mix is what makes the search for law firm payroll frustrating. The practice management platforms most firms already use, including Clio and MyCase, deliberately do not build payroll. There is no meaningful category of law-firm-native payroll software. What exists is general small business payroll, several vendors of which maintain law firm pages describing how they handle partner draws, plus separate legal accounting tools for the trust side.
This comparison covers what actually differs about paying a law firm, which of eight options fit a firm of five to fifty people, and the part of hiring an attorney that no payroll platform touches.
What makes law firm payroll different
Three characteristics, and none of them require legal-specific software. All three affect how ordinary software has to be configured.
| Role | How they are paid | Tax form | Who pays employment tax | Payroll treatment |
|---|---|---|---|---|
| Equity partner | Guaranteed payments and draws | Schedule K-1 | Self-employment tax paid by the partner | Never through payroll |
| Income partner | Salary, sometimes plus bonus | W-2 in many firms | Employer withholds and matches FICA | Through payroll, structure varies |
| Associate attorney | Salary plus bonus | W-2 | Employer withholds and matches FICA | Through payroll |
| Of counsel | Salary or contract fee | W-2 or 1099 | Depends on the working relationship | Depends on classification |
| Contract attorney | Hourly or per-matter fee | 1099 typically | Contractor pays own self-employment tax | Contractor payment, not payroll |
| Paralegal and support | Hourly or salary plus overtime | W-2 | Employer withholds and matches FICA | Through payroll |
The first is the sheer number of tax treatments running simultaneously. A firm of fifteen may have partners on K-1, associates and staff on W-2, and contract attorneys on 1099, which means the payroll system has to accommodate people who are deliberately outside the payroll run alongside those inside it. Our guide to 1099 versus W-2 classification covers the analysis that determines which category someone falls into.
The second is the trust account, covered below. The third is multi-state practice: attorneys licensed and practicing across state lines are common at firm sizes where a comparable non-legal business would still be single-state, and each additional state means registration for withholding and unemployment before anyone is paid there. Our guide to multi-state payroll processing covers the mechanics.
Why partners never run through payroll
This is the point that most surprises people arriving from a corporate background, and it is not a matter of firm preference. A partnership cannot pay W-2 wages to its own partners. The Internal Revenue Service treats a partner working for the partnership as self-employed with respect to that firm.
| Payment type | What it is | Tax treatment |
|---|---|---|
| Guaranteed payment | Fixed compensation for services, paid regardless of firm profit | Ordinary income on K-1, subject to self-employment tax |
| Draw | Withdrawal against the partner's share of profits | Distribution, reduces capital account rather than being separate income |
| Distributive share | The partner's allocated portion of firm income | Reported on K-1, general partners owe self-employment tax |
Guaranteed payments are always subject to self-employment tax, including for limited partners who would otherwise avoid it on their distributive share. The rate is 15.3 percent, made up of 12.4 percent Social Security on earnings up to the annual wage base of $184,500 for 2026 plus 2.9 percent Medicare with no cap, with an additional 0.9 percent Medicare above $200,000 for single filers and $250,000 for joint filers. Net earnings are adjusted to 92.35 percent before the calculation, and half the resulting tax is deductible.
Income partners, sometimes called non-equity partners, are a different case. Many firms treat them as employees receiving a W-2, since they hold the partner title without an equity stake. The treatment varies between firms and depends on the partnership agreement, which is one of the reasons the payroll setup conversation should involve the firm accountant rather than only the office manager.
Trust account separation is an ethics rule, not an accounting preference
Client funds held in an Interest on Lawyers Trust Account belong to the client, not to the firm. Under ABA Model Rule 1.15 and the state equivalents that nearly all jurisdictions have adopted, those funds must be kept entirely separate from the firm's own property.
Using trust funds for operating expenses, including payroll, is commingling. The consequences range from reprimand through suspension to disbarment, and the rule bites even where the mistake was unintentional and no client ultimately lost money. Trust accounting violations are among the most common sources of bar discipline nationally.
The reconciliation obligations sit alongside this. Most jurisdictions require monthly three-way reconciliation matching the bank statement, the trust ledger, and the sum of individual client ledgers. That is trust accounting work handled by legal accounting tools rather than by payroll software, and several state bars now require annual compliance certification on top.
8 payroll options for law firms compared
Seven payroll providers plus one adjacent tool. The Runs Payroll column is there because the last row does not, and that distinction matters more than any feature comparison below it.
| Provider | Best For | Starting Price | Runs Payroll | Partner K-1 Handling | Multi-State Filing | Onboarding Workflows | Trial |
|---|---|---|---|---|---|---|---|
| Gusto | Firms wanting published pricing | $49 + $6/ee | Until 1st run | ||||
| OnPay | Multi-state firms at a flat rate | $49 + $6/ee | 1 month | ||||
| SurePayroll | Solo and very small practices | $29 + $7/ee | Varies | ||||
| Paychex | Growing firms wanting an advisor | Quote | Varies | ||||
| ADP RUN | Multi-office and multi-state depth | ~$79 + $4/ee | 3 months | ||||
| Justworks | Benefits leverage through a PEO | $50 + $8/ee | Demo | ||||
| Rippling | Firms wiring payroll to HR and IT | $35 + $8/ee+ | Demo | ||||
| FirstHR | Attorney and staff onboarding only | $98-$198 flat | Free trial |
A note on the last row: FirstHR is our product. We have included it because it comes up in the same buying conversation, and we have marked its gaps in the same columns we use for everyone else. It does not run payroll, does not handle partner compensation, and does not file taxes. Read the rest of this page as a payroll comparison and treat FirstHR as the onboarding layer described further down.
Gusto
The most common first payroll purchase for US small businesses, at $49 per month plus $6 per employee on the Simple plan following a March 2026 base increase. Gusto maintains a law firm page describing support for partner draws, associate tiers, and lockstep compensation structures, and the onboarding and benefits tooling is the strongest among payroll-first providers.
The catch for firms is that Simple covers single-state payroll only. Given how often attorneys are licensed across state lines, model the Plus tier at $80 plus $12 per employee if a second state is plausible.
OnPay
One plan at $49 per month plus $6 per employee with every feature included and no tier to climb. Tax filing covers all 50 states with no multi-state surcharge, which is the specific reason to prefer it over Gusto for a firm with attorneys practicing across state lines. OnPay maintains a law firm page addressing equity and non-equity partners, contract attorneys, and trust account separation.
SurePayroll
Owned by Paychex and aimed at very small employers at roughly $29 per month plus $7 per employee, with a law firm page covering salary, draw, and profit share arrangements alongside W-2 and 1099 workers. For a solo practitioner with an assistant or a two-attorney practice, it is the cheapest credible option and the feature depth of the larger platforms is not needed.
Paychex
A service relationship rather than a software subscription, with a dedicated specialist at higher tiers and a professional employer organization option for firms wanting benefits leverage. Pricing is quote-only. Worth knowing that the American Bar Association maintains a member discount arrangement with Paychex covering payroll processing and related fees, which changes the comparison for a member firm and is not reflected in any published rate.
ADP RUN
The deepest compliance operation in the category, which for a firm with offices in several states or attorneys admitted in multiple jurisdictions is the concrete argument. Third-party estimates put the entry tier near $79 per month plus $4 per employee, but ADP does not publish rates and setup fees are common. There is no law-firm-specific landing page, so the industry framing comes from general professional services.
Justworks
Two products under one name. Payroll at $50 per month plus $8 per employee is straightforward software. The professional employer organization tier is a co-employment arrangement giving a small firm access to benefit plans priced off a much larger risk pool, which is the actual reason most firms consider it: a fifteen-person firm cannot negotiate health coverage the way a large group can.
Rippling
A unified employee record where payroll, HR, and device provisioning share one data model, starting at $35 per month plus $8 per employee for the core platform with payroll as a separate module. The IT provisioning is more relevant to a law firm than to most industries, given document management systems and the security requirements around client confidentiality, but real configurations land well above the headline figure.
Where practice management tools fit, and why they skip payroll
Firms often start this search assuming their practice management platform will handle payroll. It does not, and the pattern is consistent enough to be worth stating plainly.
| Platform | What it does | Payroll? |
|---|---|---|
| Clio | Practice management, billing, trust accounting | No native payroll; integrates with general providers |
| MyCase | Practice management and billing | No payroll |
| PracticePanther | All-in-one practice management and workflow | No payroll |
| CosmoLex | Practice management with built-in trust accounting | Through partner bookkeeping services rather than natively |
| LeanLaw | Legal billing inside QuickBooks Online | Payroll runs through QuickBooks |
| TrustBooks | Trust accounting only | No payroll |
These platforms handle the trust side, which is the genuinely legal-specific accounting problem, and hand payroll to general vendors through integrations. That is a deliberate architecture choice rather than a gap waiting to be filled, and it means the stack for most firms is practice management plus trust accounting plus a general payroll provider rather than one system doing everything.
What payroll does not cover when you hire an attorney
Every provider above pays people correctly once they are set up. None of them handles what has to happen before the first payroll run, and for a law firm that list is longer than in most industries.
| Task at hire | Why it matters | Where it usually lives |
|---|---|---|
| Bar admission verification | Confirming licensure in each practicing jurisdiction | Manual check, often unrecorded |
| Conflict of interest check | Required before the attorney touches matters | Conflicts system, certification often on paper |
| Employment and confidentiality agreements | Signed before start, retained for the relationship | Email attachments or a shared drive |
| Ethics and malpractice acknowledgment | Firm policy acknowledgment on record | Handbook signature page, if collected |
| I-9 and W-4 | Federal requirement with a three-day I-9 deadline | Payroll platform sometimes, paper often |
| Specialty certifications | Privacy, tax, or other credentials where relevant | Rarely tracked systematically |
The pattern in that right-hand column is the point. Payroll platforms calculate and pay; they do not verify a bar license, store a signed conflicts certification, or remind anyone that an I-9 is due within three business days of the start date. In a small firm this work lands on the office manager alongside everything else, and it is the part that gets discovered incomplete during an audit or a malpractice carrier review rather than at the time.
Our comparison of employee onboarding software covers that layer against the alternatives, including the platforms that bundle it with payroll.

Frequently Asked Questions
Can law firm partners be paid through payroll?
Not in a partnership. Partners cannot receive W-2 wages from the firm they own and instead take guaranteed payments and draws reported on Schedule K-1, carrying self-employment tax at 15.3 percent with the Social Security portion applying up to $184,500 for 2026. Income or non-equity partners are often treated as W-2 employees, depending on the partnership agreement.
What makes law firm payroll different from other small business payroll?
Several tax treatments run simultaneously, with partners on K-1, staff on W-2, and contract attorneys on 1099. Client funds in trust must never touch payroll. And multi-state practice is common at firm sizes where a comparable business would still be single-state.
Can a law firm pay payroll from its IOLTA trust account?
No. Under ABA Model Rule 1.15 and state equivalents, client funds must be kept entirely separate from firm property, and using them for operating expenses is commingling with consequences up to disbarment. Payroll is funded from the operating account, and the trust account should not be connected to the payroll platform at all.
Is there payroll software built specifically for law firms?
Not really. Clio, MyCase, and PracticePanther deliberately do not build payroll and integrate with general providers instead. What exists is general small business payroll, several vendors of which maintain law firm pages, plus separate trust accounting tools such as CosmoLex, LeanLaw, and TrustBooks.
How do law firms handle contract attorneys in payroll?
Usually as independent contractors paid on a 1099 rather than through the W-2 run, though classification depends on the actual working relationship rather than the engagement letter. See our guide to 1099 versus W-2 classification for the analysis.
What should a law firm look for in payroll software?
Support for paying partners outside the W-2 run, multi-state filing if attorneys practice across state lines, clean banking separation so the trust account is never connected, and off-cycle runs for bonuses without a per-run fee. Legal-specific features beyond that rarely decide it for a firm under 50 people.
How much does payroll for a law firm cost?
A 10-person firm runs roughly $99 to $150 monthly on published pricing: $109 on Gusto or OnPay, $99 on SurePayroll, $130 on Justworks payroll. Quote-based providers generally sit higher. See the payroll pricing guide for how the models compare.
What does payroll software not cover when hiring an attorney?
Bar admission verification, conflict of interest checks, signed employment and confidentiality agreements, ethics and malpractice acknowledgment, and the I-9 and W-4. See our guide to new hire paperwork for what belongs in the file.
