Pre-IPO secondaries sit at the intersection of two complicated bodies of law: federal securities law (which controls who can buy what, and how those offerings can be communicated) and federal tax law (which controls how gains are taxed, when, and at what rate). In a private market marketplace, the substantive details fill multiple textbooks. This piece compresses everything that an accredited buyer or a pre-IPO seller actually needs to know in order to make a good decision, without trying to substitute for the advice of a CPA or securities attorney.
The securities-law framework: Regulation D
Every offering on Limen Markets is a private placement under Regulation D of the Securities Act of 1933. Reg D provides issuers with safe-harbor exemptions from the SEC's full registration requirements, on the condition that offerings are limited to qualified investors and conducted within specific guardrails. Two rules within Reg D apply to virtually all Limen Markets activity:
Rule 506(c) — Accredited investors only
506(c) is the default for almost every active listing on the platform. It permits an issuer (or a vehicle on behalf of an issuer) to raise an unlimited amount of capital from an unlimited number of accredited investors, and it allows general solicitation — meaning the offering can be advertised on a public website, in marketing materials, on social media, anywhere. The catch: every investor must be verified as accredited, with documentation kept on file. A self-attestation is not enough.
On the Limen Markets platform, you complete a one-time accreditation flow at signup. We accept three forms of verification: (1) tax returns and other documentation reviewed by our compliance team; (2) a third-party verification letter from your CPA, fund administrator, or attorney dated within the last 90 days; (3) a verification letter from one of the SEC-recognized verification services. The 506(c) verification is good for five years. Once verified, every active listing on our accredited investor marketplace is available without further per-deal re-verification.
Rule 506(b) — Limited non-accredited capacity
506(b) permits an issuer to include up to 35 non-accredited investors in an offering, alongside an unlimited number of accredited investors. The non-accredited participants must meet a "sophisticated investor" standard — financial knowledge sufficient to evaluate the merits of the investment — but do not need to meet the accredited income or net-worth thresholds.
The crucial constraint: 506(b) offerings cannot be generally solicited. The issuer (or vehicle, or platform) cannot advertise the specific offering on a public website, in marketing materials, on social media, or anywhere else. This is a federal-law restriction, not a Limen Markets policy. In practice, it means Limen Markets cannot list, name, or describe specific 506(b) offerings on our website or in any public communications, including this article. If you are a non-accredited investor who has been told by us (in private communication, after we have a prior substantive relationship with you) that a 506(b) seat is available, that is the only path.
Non-accredited investors interested in 506(b) availability should contact the team directly through the chat assistant or the contact form on /about. Whether any current 506(b) offering has space, and on what terms, is something we can only discuss with you in private after a substantive relationship is established.
Who is an accredited investor
The SEC's accredited-investor definition for natural persons (as of 2026) is as follows. You qualify as accredited if any one of the following is true:
- Income test. Annual income greater than $200,000 (or $300,000 jointly with a spouse) in each of the prior two years, with a reasonable expectation of the same level in the current year.
- Net-worth test. Net worth greater than $1,000,000, alone or jointly with a spouse, excluding the value of the primary residence. The exclusion of primary residence value is important — for high-cost-of-living areas the practical net-worth bar is notably higher than the gross number suggests.
- Professional certification. Holding in good standing a Series 7, Series 65, or Series 82 license. This was added in 2020 and is a useful path for finance professionals whose personal balance sheets do not yet meet the wealth thresholds.
- Knowledgeable employee status. Being a knowledgeable employee (officer, director, or similar) of the private fund issuing the security. Limited application in the secondary context but relevant for primary-fund offerings.
Entities — institutions, family offices, trusts — qualify under separate tests. Family offices with $5M+ of investments managed on a discretionary basis qualify as accredited entity investors; institutions with $5M+ in total assets generally qualify; certain trusts qualify if the trustee directing the investment is a sophisticated person.
Tax: Qualified Small Business Stock (QSBS, Section 1202)
Section 1202 of the Internal Revenue Code is the most powerful tax provision in the pre-IPO space and the one most often misunderstood. Properly qualified QSBS stock can receive a 100% federal capital-gains exclusion on the first $10 million of gain (or 10x the original basis, whichever is greater) per issuer, per taxpayer. For an individual selling $10M of qualified pre-IPO stock at a sufficient gain, that exclusion can be worth $2-2.4M in federal tax savings.
The qualification rules are technical and the most common ways stock loses QSBS treatment are subtle. The complete walk-through is at /resources/qsbs-section-1202, but the headline tests are: (a) the issuer must have been a domestic C-corporation with <$50M in gross assets at the time the stock was issued; (b) the issuer must have been engaged in a qualified active trade or business; (c) the stock must have been originally issued by the company (not purchased on the secondary market); (d) the stock must be held for at least five years before sale; (e) the issuer must satisfy ongoing active-business tests during the holding period.
The (c) point is the one that catches secondary buyers off guard. If you buy pre-IPO equity on the secondary market, your stock is not QSBS-eligible — it was originally issued to someone else. QSBS is a seller-side benefit, available only to investors who purchased their stock directly from the issuer in a primary round (or as compensation, for employees). Secondary buyers should not assume any QSBS benefit on resale.
Tax: the 83(b) election
For sellers — employees and founders with vesting equity — the 83(b) election is one of the most consequential tax decisions in pre-IPO ownership. We have a complete walkthrough at /resources/83b-elections, but the short version is this: when you receive restricted stock that vests over time, you have a choice. You can pay ordinary income tax on the value of the stock as it vests each year, at then-current fair-market value (the default treatment), or you can elect under Section 83(b) to pay all the income tax up front, on the value at grant, and receive long-term capital-gains treatment on all future appreciation when you sell.
For early-stage equity granted at a low fair-market value, an 83(b) election is almost always correct. For later-stage equity, the math is more complex. The election must be filed with the IRS within 30 days of grant; missing the window is irreversible. If you exercised early but missed the 83(b) window, your sale economics will look different than you expect — work through them with a CPA before pricing your shares. For employees with Incentive Stock Options approaching exercise, separate AMT considerations apply that can produce a real cash tax bill in the exercise year even if the shares are illiquid.
The 409A valuation and what it means for buyers
409A is the section of the tax code requiring private companies to obtain an independent third-party valuation of their common stock for purposes of pricing employee stock options. The 409A valuation is conservative by design — it is meant to be defensible to the IRS as fair market value, not to reflect the strike price of the latest secondary trade. For a typical late-stage private company in 2026, the 409A valuation runs 20-40% below the most recent primary-round price, and 30-50% below the secondary market reference price.
Why does this matter for a secondary buyer? Two reasons. First, the gap between 409A and the secondary mark is one of the most-cited indicators of overheating in the pre-IPO market — when the gap widens dramatically, late-arriving secondary buyers are paying a premium that the company's own auditors think is not defensible. Second, the 409A is a useful sanity check: if you are being asked to pay a price that is 5x or more above the most recent 409A, you should be able to articulate why.
The full mechanics of 409A versus the secondary mark are at /resources/409a-vs-secondary.
ROFR: right of first refusal
Most issuer transfer policies include a right of first refusal (ROFR) giving the company or its existing investors the right to match any third-party offer to buy shares from an existing holder. ROFR is a structural feature that the buyer needs to understand because even after you have signed documents and committed funds, the issuer can pull rank and your trade will not close. The buyer is made whole financially — funds held in escrow are returned — but loses the time spent on the transaction and the position they expected. Sellers should also understand post-IPO seller obligations that can apply after the company lists, including representation breaches and clawback exposure.
In practice, ROFR exercise on secondary trades runs in the single digits as a percentage of attempted trades, but varies dramatically by issuer. Some companies routinely waive; some routinely exercise. The complete mechanics, including how Limen Markets clears ROFR in parallel with execution rather than sequentially, are at /resources/rofr-navigation.
K-1 reporting for SPV investors
When you buy a Limen Markets offering as an SPV interest, you are an LP in a limited liability company. The LLC is a pass-through entity for tax purposes — it does not pay federal income tax, and instead passes income, gains, and losses through to its LPs (you). At year-end, the LLC issues each LP a Schedule K-1 reporting their share of the LLC's tax items.
K-1s create three practical complications. First, they typically arrive in March or April rather than in time for the original April 15 personal-tax filing deadline, so you will need to file an automatic extension on your personal return. Second, if the SPV's investments span multiple states, you may receive K-1 line items requiring state-level filings in those states — most secondary SPVs are structured to minimize this, but it is worth asking. Third, certain SPV-level expenses (management fee, organizational costs) flow through to the K-1 and may or may not be deductible at the individual level depending on your situation.
None of this is unusual — every venture or private-equity fund LP deals with these mechanics — but if it is your first SPV investment, allocate time with your CPA in March of the year after your initial purchase. We provide K-1s electronically and notify LPs as soon as they are available. For deeper guidance on the timing and tax-planning side of holding an SPV interest through to exit, see our walkthrough on K-1 planning.
State tax considerations, briefly
Capital-gains treatment varies meaningfully by state — see our deeper write-up on secondary sale tax residency timing. California taxes long-term capital gains as ordinary income (top rate around 13.3% as of 2026). Florida, Texas, Tennessee, Nevada, Washington, Wyoming, South Dakota, and New Hampshire have no state-level capital-gains tax. New York has a top state-level cap-gains rate around 8.82%. For a New York or California resident selling a meaningfully appreciated pre-IPO position, the state tax can be a significant percentage of total tax owed — and the state of residency at the time of sale generally controls.
None of this is a recommendation to relocate. But if you have flexibility on the timing of a sale and you are contemplating a move to a no-tax state for other reasons, the state-level tax line item is meaningful enough to discuss with your CPA before timing the sale.
Holding period and what it does to your rate
Federal tax treatment of investment gains hinges on the holding period. Gains realized on assets held one year or less are taxed at ordinary-income rates (37% top federal bracket as of 2026, plus the 3.8% net investment income tax). Gains realized after holding more than one year qualify for long-term capital-gains treatment (20% top federal bracket, plus 3.8% NIIT).
For SPV-wrapped secondary positions, the holding-period clock starts when you acquire the LLC interest, not when the underlying shares were originally issued. For the relationship between trade timing and primary-market activity, see our note on secondary sale timing around fundraising rounds. Pre-IPO secondaries are typically held 3-7 years before liquidity, so the holding-period question rarely becomes a constraint on rate — but it is worth understanding before you sell partial position.
Disclosures and what we are not
Limen Markets is not a broker-dealer, investment adviser, accountant, or law firm. Nothing on the platform or in this article constitutes a recommendation to buy or sell a specific security, investment advice, tax advice, or legal advice. All Limen Markets offerings are private placements that involve a high degree of risk, including the possible loss of the entire investment. Investments are speculative, illiquid, and may take five or more years to realize a return — or may not realize a return at all. Past performance is not a reliable indicator of future results. Pricing information displayed on the platform is informational and does not represent a quote or offer to transact at any specific price or quantity.
