Making partner at a law firm means you stop being an employee and become a co-owner of the business. That one change ripples through everything: you buy into the firm with your own capital, your paycheck turns into a share of profits, you file taxes as a self-employed person, you get a vote on how the firm is run, and you take on fiduciary duties to your fellow partners. The upside is ownership and a share of what the firm earns. The trade-off is that your income rises and falls with the firm, and some of the protections you had as an employee go away.
Before anything else, confirm which kind of partner you are being offered. The title by itself doesn’t tell you.
Equity Partner or Non-Equity Partner
Many firms run a two-tier partnership, and the two tiers are different jobs.
A non-equity partner holds the title and usually earns more than associates, but doesn’t own a share of the firm. They’re paid a salary, sometimes with a bonus, remain employees for tax purposes, and generally don’t vote on major firm decisions or put in capital. Promotion to the non-equity tier often happens after roughly seven to nine years of practice.
An equity partner owns a piece of the firm, contributes capital, shares in profits and losses, votes on governance, and is treated as self-employed by the IRS. Elevation to equity typically takes longer than the move to non-equity and is evaluated separately, often on the lawyer’s ability to generate sustained revenue and bring in clients. Many firms use the non-equity role as a proving ground before a vote on full admission.
The rest of what follows describes equity partnership. If your offer is non-equity, most of the tax and liability changes don’t apply to you yet.
The Capital Buy-In
Equity partners are expected to put money into the firm. The capital contribution funds operations and corresponds to your proportional ownership stake. Amounts range widely — some smaller firms require nothing, and larger firms can ask for six figures. New partners typically cover the buy-in through personal savings, a bank loan, or an installment plan the firm itself offers.
That capital stays in the firm while you’re a partner. When and how you get it back when you leave is set by the partnership agreement, not by any default rule, so read that section carefully before you sign.
How You Get Paid as a Partner
Equity partners don’t draw a salary. You take home a share of the firm’s net profits after expenses. Firms generally use one of two models to split those profits, or some blend of them:
- Origination-based, sometimes called “eat what you kill,” ties your compensation closely to the revenue you personally generate. More clients and more billings mean a bigger share.
- Lockstep raises your pay automatically with seniority, in predictable steps for each year of service, regardless of individual billing.
Many firms blend the two, mixing seniority with individual performance metrics. The important point for your planning is that partner pay fluctuates. A lean year — lost clients, higher overhead, a downturn — can shrink distributions to keep the firm stable. Household budgeting that worked on a steady associate salary needs to be rebuilt around variable income.
Your Taxes Work Completely Differently
The move from W-2 associate to partner is the biggest practical shift in your financial life, because the IRS now treats you as an owner of a pass-through business rather than an employee.
K-1 Instead of W-2
The firm files an informational return (Form 1065) with the IRS but doesn’t pay income tax at the entity level. Instead, it issues each partner a Schedule K-1 showing that partner’s share of income, deductions, and credits, and you report those figures on your personal Form 1040.1Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income Income passes through to you whether or not the firm actually distributes the cash, which means you can owe tax on money you haven’t yet received.
Self-Employment Tax
As an associate, your employer paid half of your Social Security and Medicare taxes. As a partner, you owe the full combined rate yourself: 15.3%, made up of 12.4% for Social Security and 2.9% for Medicare.2Internal Revenue Service. Form 1040-ES Estimated Tax for Individuals A few details change the real number:
- The 12.4% Social Security portion applies only to earnings up to $184,500 in 2026. Income above that isn’t subject to the Social Security tax.3Social Security Administration. Contribution and Benefit Base
- You can deduct half of your self-employment tax above the line when calculating adjusted gross income.
- If your self-employment income tops $200,000, or $250,000 filing jointly, you owe an additional 0.9% Medicare surtax on the amount over that threshold.4Internal Revenue Service. Topic No. 560, Additional Medicare Tax
Quarterly Estimated Payments
Nobody is withholding tax from your draws. You pay the IRS yourself, four times a year. For 2026, estimated payments are due April 15, June 15, September 15, and January 15, 2027.2Internal Revenue Service. Form 1040-ES Estimated Tax for Individuals The requirement to make them generally kicks in if you expect to owe at least $1,000 after any withholding and credits. Underpaying or missing a deadline brings a penalty, which is why many new partners work closely with an accountant in their first year.
The Section 199A Deduction, With a Catch
Owners of pass-through businesses may deduct up to 20% of qualified business income under Section 199A, a deduction made permanent in 2025.5Internal Revenue Service. Qualified Business Income Deduction Legal services, though, are a “specified service trade or business,” so the deduction phases out as taxable income rises. Many equity partners at mid-size and large firms earn above the phase-out and see little or no benefit.
Retirement Is on You
There’s no employer match once you’re a partner. Funding retirement is entirely your responsibility. In 2026, you can defer up to $24,500 into a 401(k) (with catch-up contributions available at 50 or older), and total defined contributions from all sources can reach $72,000.6Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs Some firms also sponsor cash balance plans that allow substantially higher annual deductible contributions, which can be useful for sheltering income once your earnings climb.
A Vote on How the Firm Is Run
With equity comes a voice in governance. Partners typically vote on admitting new partners, approving mergers, setting strategic direction, and amending the partnership agreement itself. Whether each partner has one equal vote or a vote weighted by equity share is spelled out in the agreement.
Day-to-day operations are usually run by a managing partner or an executive committee rather than put to the full partnership. The biggest decisions — dissolving the firm, taking on major debt, changing the profit-sharing formula — often require a supermajority such as two-thirds or three-quarters approval.
Fiduciary Duties and Personal Liability
Partners owe each other legally enforceable fiduciary duties. The duty of loyalty means you can’t use your position for personal gain at the firm’s expense, secretly compete, or divert business opportunities away from the partnership. The duty of care requires you to stay reasonably informed and act with diligence on decisions that affect the firm.7LII / Legal Information Institute. Fiduciary Duty A breach can bring suit from your fellow partners and expulsion under the agreement.
Most modern firms organize as Limited Liability Partnerships. An LLP generally shields you from personal responsibility for another partner’s malpractice or negligence. It does not shield you from your own professional errors, and depending on state law, you may still share responsibility for the firm’s contractual obligations such as office leases and credit lines.8LII / Legal Information Institute. Limited Liability Partnership (LLP) LLP protection varies by state, so know exactly what your firm’s structure does and doesn’t cover.
What Happens If You Leave
Partnership isn’t permanent, and the exit mechanics matter as much as the entry ones.
Partnership agreements commonly require 60 to 90 days of written notice before withdrawal takes effect. The firm owes you a return of your capital contribution when you leave, but many firms repay in installments over months or years rather than in a lump sum, since the money comes from ongoing revenue. The agreement should spell out how your capital account is valued at departure and what the payment schedule looks like.
Lawyers get a protection most professionals don’t. The American Bar Association’s Model Rule 5.6, adopted in some form by nearly every state, prohibits partnership agreements from restricting a lawyer’s right to practice after leaving, with a narrow exception tied to retirement benefits.9American Bar Association. Rule 5.6 Restrictions on Rights to Practice A firm generally can’t force you to forfeit compensation or impose financial penalties for taking clients when you go, and courts have consistently struck down provisions that create financial disincentives to compete.
One last item worth checking before you accept, and again before you leave: malpractice tail coverage. If the firm’s malpractice policy is claims-made, it only covers claims filed during the policy period. Tail coverage extends protection for claims that come in after your departure but relate to work you did at the firm. It isn’t included automatically and must be purchased separately. The cost can run well over twice the expiring annual premium, and the partnership agreement should say whether the firm or the departing partner pays. Without it, you can remain personally exposed to malpractice claims for years after you leave.
