Employee investment in private equity funds happens through two channels that work very differently: co-investment, where you commit your own after-tax cash alongside outside limited partners, and carried interest, where you receive a share of fund profits without putting up capital. Co-investment gives you better economics than any outside LP gets. Carry is where the real wealth builds, but only if the fund performs and only if you stay long enough to vest. Both lock your money and your upside into a vehicle that may not return cash for a decade, and both come with tax rules that can produce a bill before you see a dollar.
What follows is what an employee actually needs to understand before signing the subscription documents.
How Co-Investment Works
Co-investment means committing personal, after-tax money directly into the deals the fund makes. Your capital sits alongside the outside LPs and the GP, and when a portfolio company is sold at a profit, you receive your proportionate share.
Employee terms are consistently better than what outside investors get. Most firms waive or heavily reduce the standard annual management fee on employee co-invested capital, which flows straight to your net return. The carried interest rate charged on employee money is also usually reduced, a typical split being 10% of profits versus the 20% charged to outside LPs. These concessions reflect the role employees play in sourcing and running the deals.
The mechanics track the main fund. You face capital calls on the fund’s schedule, receive distributions pro rata, and your commitment is often subject to a vesting schedule tied to continued employment. Leaving early can mean forfeiting unvested commitments or losing the preferential fee and carry terms you had.
How Carried Interest Works
Carried interest, often called the promote, is a share of the fund’s profits. You don’t contribute capital to receive it. It kicks in only after outside LPs have earned a preferred return, typically 7% to 8% annually. Above that hurdle, the GP entity collectively receives around 20% of profits, and individual employees get a slice of that 20% based on seniority, tenure, and contribution.
The leverage is substantial. A small percentage interest in the GP can translate into millions of dollars in a large, successful fund. The payout is also entirely contingent: if the fund fails to clear the preferred return, carry is worth zero.
Carry allocations come with clawback provisions. If the fund distributes carry on early winners and later investments drag overall performance below the preferred return, you have to return previously distributed carry. You will already have paid tax on that money, which creates its own financial planning problem.
Vesting and What Happens When You Leave
Carry almost never vests all at once. Firms use multi-year schedules to keep professionals committed across the fund’s full lifecycle, which can run a decade or more. One common structure vests 80% over the first five years and the remaining 20% over the following five. Others use straight-line vesting at 10% per year for ten years. Some back-load a portion so it only vests when the fund winds down.
Most firms impose a one- or two-year cliff. An employee who leaves before the cliff forfeits the entire carry allocation. After the cliff, unvested carry is typically forfeited on departure, and whether your vested carry survives depends on the partnership agreement’s “good leaver” and “bad leaver” definitions.
A bad leaver — someone terminated for cause — may be forced to sell their interest back to the GP at a steep discount and forfeits any unvested carry. A good leaver, such as someone who retires or exits on amicable terms, may retain their vested interest but typically loses the right to future carry allocations and has limited governance rights going forward. Read these provisions carefully before you accept the grant, not when you’re negotiating a departure.
The Section 83(b) Election and Its 30-Day Deadline
When you receive carried interest or a restricted equity stake subject to vesting, Section 83 of the Internal Revenue Code decides when the tax hits. The default rule is that you owe tax when the interest vests, not when it’s granted. In a successful fund, the difference between grant-date value and vesting-date value can be enormous.
Section 83(b) lets you elect to pay tax on the interest’s value at grant instead.1Office of the Law Revision Counsel. 26 USC 83 – Property Transferred in Connection With Performance of Services A newly issued carried interest usually has little or no current fair market value, so the election often means paying little or no tax upfront. All future appreciation then qualifies for capital gains treatment when the interest is sold or the fund distributes profits, rather than being taxed as ordinary income at vesting.
The deadline is strict. The election must be filed with the IRS within 30 days of the property transfer, using Form 15620.1Office of the Law Revision Counsel. 26 USC 83 – Property Transferred in Connection With Performance of Services There are no extensions and no exceptions. Miss the window and the election is gone for that grant. File it with the IRS office where you file your return, and send it certified mail with return receipt as proof of timely filing.
The risk is forfeiture. If you leave before vesting and lose the interest, you cannot deduct the tax you already paid. For most PE professionals receiving carry at or near zero value, the election is close to automatic. The 30-day clock makes it one of the easiest high-stakes mistakes in the industry.
How Co-Investment Returns Are Taxed
Because co-investment uses your own capital, returns follow ordinary investment-income rules. The holding period of the underlying asset sets the tax rate. If the fund sells a portfolio company you’ve been exposed to for more than a year, the gain is a long-term capital gain taxed at a maximum federal rate of 20%.2Internal Revenue Service. Topic No. 409 – Capital Gains and Losses Sales within a year produce short-term gains taxed at ordinary rates topping out at 37%.3Internal Revenue Service. Federal Income Tax Rates and Brackets
High-earning employees will almost certainly also owe the 3.8% Net Investment Income Tax on their gains. The NIIT applies at modified adjusted gross income above $200,000 for single filers or $250,000 for joint filers, and those thresholds are not indexed for inflation.4Internal Revenue Service. Topic No. 559 – Net Investment Income Tax The effective top federal rate on long-term co-investment gains is 23.8%.
You’ll receive a Schedule K-1 from the co-investment vehicle reporting your share of income, deductions, and credits, which you report on your personal return.5Internal Revenue Service. Partner’s Instructions for Schedule K-1 (Form 1065) It will be separate from any K-1 you receive for carry.
How Carried Interest Is Taxed
Carried interest has its own special rule. Section 1061 requires a three-year holding period for carry gains to qualify for long-term capital gains treatment, not the standard one year that applies to ordinary investment income.6Office of the Law Revision Counsel. 26 USC 1061 – Partnership Interests Held in Connection With Performance of Services If the fund sells a portfolio company before holding it for three years, the carry allocated to you is recharacterized as short-term capital gain and taxed at ordinary rates up to 37%.7Internal Revenue Service. Section 1061 Reporting Guidance FAQs
For assets held beyond three years, the carry qualifies for the 20% long-term rate plus the 3.8% NIIT, totaling 23.8% for high earners. The three-year rule is one reason PE hold periods tend to cluster around four to six years. A single fund distribution can mix long-term and short-term gains depending on when each portfolio company was sold, so the K-1 line items matter.
You’re generally not taxed on carry until the fund actually sells an asset and realizes a gain. Timing complications still arrive, in two forms.
Phantom Income and Clawbacks
Partnership tax rules can produce a bill before cash reaches your account. When the fund realizes a gain, your allocable share is taxable income for that year even if the fund retains the cash for reserves, follow-on investments, or future calls. This gap between tax liability and cash in hand is phantom income. Many firms make tax distributions specifically to cover it, but not all do, and not always in full. Plan on bridging the shortfall.
Clawbacks compound the timing problem. You receive a carry distribution, pay tax on it, and years later the fund underperforms and triggers a clawback. You have to return cash you’ve already been taxed on. Section 1341 provides relief by letting you either deduct the repaid amount or claim a credit equal to the tax originally paid on that income, whichever produces the lower bill in the repayment year.8Office of the Law Revision Counsel. 26 USC 1341 – Computation of Tax Where Taxpayer Restores Substantial Amount Held Under Claim of Right The relief only applies when the repayment exceeds $3,000, and the mechanics are complex enough that most people need specialized tax counsel for a clawback year.
One more wrinkle: a fund operating across multiple states can create filing requirements for you in each state where it has portfolio companies or does business. Many states tax capital gains at ordinary rates, so the federal long-term preference doesn’t necessarily carry through at the state level.
Who Is Allowed to Invest
Federal securities law restricts private fund participation to investors meeting specific financial thresholds. The baseline is accredited investor status, which you qualify for through either a net worth or an income test. The net worth test requires more than $1 million in net worth, excluding the value of a primary residence.9U.S. Securities and Exchange Commission. Accredited Investor Net Worth Standard The income test requires individual income above $200,000, or joint income above $300,000, in each of the prior two years with a reasonable expectation of maintaining that level.10U.S. Securities and Exchange Commission. Accredited Investors
Larger or more complex funds that rely on the Section 3(c)(7) exemption under the Investment Company Act of 1940 require a higher threshold: qualified purchaser status.11Office of the Law Revision Counsel. 15 USC 80a-3 – Definition of Investment Company For individuals, that means owning at least $5 million in investments, well beyond what most junior and mid-level employees have.
The Knowledgeable Employee Exception
SEC Rule 3c-5 provides a carve-out that most of the PE compensation model depends on. Securities owned by “knowledgeable employees” of the fund’s management company are excluded when counting investors for both the 3(c)(1) 100-investor limit and the 3(c)(7) qualified purchaser requirement.12eCFR. 17 CFR 270.3c-5 – Beneficial Ownership by Knowledgeable Employees and Certain Other Persons
Two categories qualify. The first covers executive officers, directors, and advisory board members of the fund or its affiliated management company. The second covers employees who participate in the fund’s investment activities as part of their regular duties, meaning deal team members, portfolio managers, and investment committee participants. Clerical or administrative staff do not qualify, and investment professionals in the second category must have at least 12 months of experience performing substantially similar functions.12eCFR. 17 CFR 270.3c-5 – Beneficial Ownership by Knowledgeable Employees and Certain Other Persons
This is what lets relatively junior deal professionals invest in the fund even without a $1 million net worth. Without the exception, much of the industry’s standard co-investment and carry structure would be off-limits to the people actually doing the work.
Funding Your Capital Commitment
Capital calls arrive on the fund’s schedule, not yours, and the amounts can be large relative to liquid savings. This is a particular problem earlier in a career.
Many firms address it through partner loan programs or co-investment credit facilities. These are lines of credit, often negotiated by the firm, that let employees borrow against future distributions or other collateral to meet capital calls. Because the firm’s credit reputation backs the facility, rates and terms are generally better than an individual could get alone.
Structures vary. Sometimes employees borrow directly and the firm guarantees the loan. Sometimes the firm or an employee co-investment vehicle is the named borrower, with individual employees as guarantors. Your partnership interest and future distributions typically serve as collateral.
Pay close attention to whether the loan is recourse or non-recourse. A recourse loan lets the lender pursue your personal assets beyond the collateral if the investment loses value. A non-recourse loan limits the lender’s recovery to the pledged collateral, carries a higher interest rate to compensate for that limitation, and caps your downside. Know which you’re signing before committing.
Liquidity and the Cost of a Missed Call
Private equity interests are among the most illiquid assets an individual can own. Committed capital is locked for the life of the fund, usually 10 to 12 years. There is no exchange or ready secondary market. The only liquidity comes when the fund sells a portfolio company, and even then distributions flow through the fund’s waterfall before reaching you.
Failing to meet a capital call puts you in one of the worst positions an investor can be in. The partnership agreement spells out the consequences, and they are designed to be punitive. Typical penalties include interest on the unpaid amount, a forced sale of your interest at a discount, or outright forfeiture of the entire investment. The GP usually has discretion over how harshly to enforce these provisions, but relying on leniency is not a plan. Make sure you have a realistic way to fund every call before you commit to the first one.
Retirement Accounts Generally Won’t Work
Employees sometimes ask about investing through an IRA or self-directed 401(k). It’s rarely practical. The Employee Retirement Income Security Act imposes fiduciary duties and prohibited transaction rules on plan assets, and most PE funds are structured specifically to avoid being classified as holding plan assets. The threshold: if 25% or more of the value of any class of equity interests in the fund is held by benefit plan investors, including IRAs and 401(k) plans, the fund’s underlying assets are treated as plan assets subject to ERISA.13GovInfo. 29 CFR 2510.3-101 – Plan Investments Funds monitor and cap benefit-plan participation below that line.
Combined with the difficulty of valuing illiquid PE interests for retirement account reporting, this is why most firms either prohibit or severely limit employee investment through retirement accounts. If you were planning on that route, assume it isn’t open and confirm with the firm before building a strategy around it.
