Employees at a private equity firm invest in their own funds through two channels that work in very different ways. The first is co-investment: you commit personal after-tax dollars alongside the fund’s outside limited partners and share in gains pro-rata. The second is carried interest, a share of the fund’s profits that costs you nothing upfront but only pays out once outside investors have earned their preferred return. Both channels can build serious wealth. Both come with vesting schedules, tax rules that reward patience, and lock-ups that stretch a decade or more.
Co-Investment: Committing Your Own Capital
Co-investment means you write a check into the same deals the fund is doing. Your capital sits alongside outside LPs and the general partner, and when a portfolio company is sold at a profit, you receive a proportionate share of the gain.
The economic terms for employees are almost always better than what outside investors get. Most firms waive or heavily reduce the annual management fee on employee co-invested capital. Employees also commonly pay a reduced carry rate on their own co-investment. A typical arrangement charges the employee 10% of profits instead of the 20% charged to outside LPs. These preferential terms compensate you for the work of sourcing and managing the deals.
Co-investments are usually structured through a limited partnership interest or a parallel vehicle. You face the same capital calls as the main fund and receive distributions on the same pro-rata basis. Commitments are often subject to vesting tied to continued employment, so leaving early can mean losing preferential terms or forfeiting unvested commitments.
Carried Interest: The Profit Share
Carried interest is where the largest wealth accumulation happens for senior PE professionals. Unlike co-investment, carry does not require you to put up personal capital. It is a share of fund profits that only kicks in after outside LPs have earned a preferred return, typically 7% to 8% annually. The GP entity collectively receives around 20% of profits above that hurdle, and individual employees get a slice of that 20% based on seniority, tenure, and contribution.
The leverage is significant. A small percentage interest in the GP can translate into millions of dollars in a large, successful fund. The payout is entirely contingent on the fund actually generating returns above the preferred return. If the fund performs poorly, the carry is worth nothing.
Carry allocations are subject to clawback provisions. If the fund distributes carry based on early winners and later investments drag overall performance below the preferred return, you must return previously distributed carry. You will already have paid tax on that money, which creates a real planning problem addressed further down.
Vesting and Leaving the Firm
Carried interest almost never vests all at once. Firms use vesting schedules to keep employees committed across the fund’s full lifecycle. One common structure vests 80% of a carry allocation 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 vests only when the fund winds down.
Most firms impose a one- or two-year cliff. An employee who leaves during that initial period forfeits the entire carry allocation. After the cliff, unvested carry is typically forfeited on departure.
What happens to vested carry when you leave depends on how the partnership agreement classifies you. A “bad leaver,” meaning 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 leaves on amicable terms, may retain vested interests but typically loses the right to future carry allocations and has limited governance rights going forward.
Funding Your Capital Calls
Coming up with cash for co-investment commitments is a real problem, especially earlier in a career. Capital calls arrive on the fund’s schedule, not yours, and the amounts can be large relative to liquid savings.
Many firms address this through partner loan programs or co-investment credit facilities. These are lines of credit, often negotiated by the firm on behalf of employees, that let you borrow against future distributions or other collateral to meet capital calls. Because the firm’s credit reputation backs these facilities, employees generally get better interest rates and terms than they could secure individually.
Structures vary. Sometimes employees borrow directly with the firm guaranteeing the loans. In other cases the firm or an employee co-investment vehicle is the named borrower and individual employees serve as guarantors. Your partnership interest and future distributions typically serve as collateral.
Recourse matters. With a recourse loan, the lender can pursue your personal assets beyond the collateral if the investment loses value. With a non-recourse loan, the lender’s recovery is limited to the pledged collateral. Non-recourse loans carry higher interest rates in exchange for capping your downside. Know which you are signing before you commit.
The Section 83(b) Election and Its 30-Day Deadline
When you receive a carried interest or restricted equity stake subject to vesting, Section 83 of the Internal Revenue Code controls how and when it gets taxed. By default, you owe tax when the interest vests, not when it is granted. For carry in a successful fund, the difference between grant-date value and vesting-date value can be enormous.
Section 83(b) offers an alternative. You can elect to pay tax on the interest’s value at the time of the grant, before it vests.1Office of the Law Revision Counsel. 26 USC 83 – Property Transferred in Connection With Performance of Services For a newly issued carried interest with little or no current fair market value, that 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 catch is the deadline. 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 No extensions, no exceptions. Miss the window and the election is gone permanently for that grant. Mail the form to the IRS office where you file your return, and send it certified with a return receipt as proof of timely filing.
The risk with an 83(b) election is forfeiture. If you leave before vesting and forfeit the interest, you cannot deduct the tax you already paid. For most PE professionals receiving carried interest at or near zero value, filing 83(b) is close to automatic. The 30-day window makes it one of the easiest high-stakes mistakes in the industry.
How Co-Investment Gains Are Taxed
Because you have committed personal capital, co-investment returns follow the standard rules for investment income. The holding period of the underlying asset sets the rate. If the fund sells a portfolio company held for more than one year, your allocable gain is a long-term capital gain at a maximum federal rate of 20%.2Internal Revenue Service. Topic No. 409 – Capital Gains and Losses Sales within one year produce short-term gains taxed at ordinary income rates that top out at 37%.3Internal Revenue Service. Federal Income Tax Rates and Brackets
High-earning PE employees will also owe the 3.8% Net Investment Income Tax. The NIIT applies to modified adjusted gross income above $200,000 for single filers or $250,000 for married couples filing jointly, and these thresholds are not indexed for inflation.4Internal Revenue Service. Topic No. 559 – Net Investment Income Tax Combined with the 20% capital gains rate, the top effective federal rate on long-term co-investment gains is 23.8%.
You will receive a Schedule K-1 from the co-investment vehicle reporting your proportionate share of income, deductions, and credits.5Internal Revenue Service. Partner’s Instructions for Schedule K-1 (Form 1065) This K-1 is separate from any K-1 you receive for carried interest.
How Carried Interest Is Taxed: The Three-Year Rule
Carry does not get the ordinary one-year holding period. Section 1061 of the Internal Revenue Code requires a three-year holding period for carried interest gains to qualify for long-term capital gains treatment.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 the 36-month mark, the carry allocated to you is recharacterized as short-term capital gain and taxed at ordinary income rates up to 37%.7Internal Revenue Service. Section 1061 Reporting Guidance FAQs
For assets held past three years, the carry qualifies for the 20% long-term rate, plus the 3.8% NIIT for high earners, totaling 23.8%. A single distribution can contain a mix of long-term and short-term gains depending on when each underlying portfolio company was sold, so accurate K-1 reporting matters.
Timing Traps: Phantom Income, Clawback Tax, and Multi-State Filings
Phantom Income
Partnership taxation can create situations where you owe tax before receiving any cash. When the fund realizes a gain on a sale, your allocable share of that gain is taxable income for the year even if the fund retains the cash for reserves, follow-on investments, or future capital calls. This mismatch between tax liability and cash in hand is called phantom income. Some firms make tax distributions specifically to cover the gap. Not all do, and not always in full.
Clawback Repayment
Clawbacks compound the timing problem. You receive a carry distribution, pay tax on it, and years later the fund underperforms and triggers a clawback obligation. You must return cash you have already been taxed on. Section 1341 provides relief by letting the taxpayer either deduct the repaid amount or claim a credit equal to the tax originally paid on that income, whichever produces a lower tax 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 This only applies when the repayment exceeds $3,000. The mechanics are complex enough that most PE professionals need specialized tax counsel in a clawback year.
Multi-State Filings
PE funds operate across multiple states, and a fund’s activity in a given state can trigger a filing requirement for each individual partner. You may need to file returns in every state where the fund has portfolio companies or does business. Many states tax capital gains at the same rate as ordinary income, so the federal preference for long-term gains does not always translate into state-level savings.
Whether You Are Even Eligible
Accredited Investor
Federal securities law restricts participation in private funds to investors who meet defined financial thresholds. The baseline is accredited investor status. You qualify by meeting either a net worth or an income test. The net worth test requires more than $1 million in net worth, excluding the value of your 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 with a spouse 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
Qualified Purchaser
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. The bar is dramatically higher than the accredited investor standard and excludes most junior and mid-level employees on paper.
The Knowledgeable Employee Exception
This is the door that opens PE fund investing to employees who do not yet meet the financial thresholds. SEC Rule 3c-5 provides a carve-out for “knowledgeable employees” of the fund’s management company. Securities owned by knowledgeable employees are excluded when counting investors for both the 3(c)(1) limit of 100 investors and the 3(c)(7) qualified purchaser requirement.12eCFR. 17 CFR 270.3c-5 – Beneficial Ownership by Knowledgeable Employees and Certain Other Persons
You qualify in one of two ways. The first category 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, such as deal team members, portfolio managers, and investment committee participants. Employees performing only clerical or administrative functions do not qualify.12eCFR. 17 CFR 270.3c-5 – Beneficial Ownership by Knowledgeable Employees and Certain Other Persons Investment professionals in the second category must also have at least 12 months of experience performing substantially similar functions.
This exception is what allows relatively junior deal professionals to invest even when they do not have a $1 million net worth.
Lock-Up and Capital Call Default
Private equity is among the most illiquid asset classes an individual can hold. Committed capital is locked up for the life of the fund, typically 10 to 12 years. There is no exchange or secondary market where you can sell your interest when you need cash. The only liquidity events come when the fund sells a portfolio company, and distributions flow through the fund’s waterfall structure before reaching you.
Failing to meet a capital call is one of the worst positions you can be in as an employee investor. The partnership agreement governs the consequences and the consequences are designed to be punitive. Typical penalties include interest on unpaid amounts, forced sale of the defaulting partner’s interest at a discount, or outright forfeiture of the entire investment. The GP usually has discretion over how strictly to enforce these provisions. Relying on leniency is not a plan. Have a realistic funding source for every capital call before you commit.
Retirement Accounts Are Generally Not a Path
Employees occasionally ask about investing in a PE fund through an IRA or self-directed 401(k). This runs into the Employee Retirement Income Security Act. Most PE funds are structured to avoid being classified as holding “plan assets” under ERISA. The key threshold: if 25% or more of the value of any class of equity interests 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’s fiduciary and prohibited transaction rules.13GovInfo. 29 CFR 2510.3-101 – Plan Investments Funds monitor and cap benefit plan investor participation below that line. As a practical matter, most PE firms either prohibit or severely limit employee investment through retirement accounts.
