How Startup Employees Can Sell Private Shares Before an IPO
Private company stock is hard to sell. The two usual routes are a company-run tender offer and a one-off secondary sale the company must approve, and each has its own paperwork, price and tax result.
Startup employees can usually sell private shares before an IPO in two ways: a company-run tender offer, where the company or investors buy shares at a set price during a fixed window, or an individual secondary sale that the company must approve. Both are limited by the transfer restrictions and right of first refusal in your stock agreements, bylaws and equity plan.
Those documents decide almost everything: whether you can sell at all, to whom, how much and with what notice. Ask the equity administrator or stock plan team for copies before you talk to any buyer.
What is a company-run tender offer?
A tender offer is an organized buyback or investor purchase that the company sets up for current and sometimes former employees. The buyer is the company itself, an existing investor, or a new investor who wants a larger stake. Everyone eligible gets the same price and the same deadline.
Tender offers in private companies generally follow the SEC’s tender offer rules in Regulation 14E, which require the offer to stay open at least 20 business days under Rule 14e-1. The packet usually includes an offer to purchase, a letter of transmittal or election form, company financial information and a tax summary.
Common limits you will see in the offer documents:
- a cap on how much each person can sell, often stated as a percentage of vested shares;
- eligibility rules, such as minimum tenure or exclusion of people who left the company;
- a total size, with proration if employees offer more shares than the buyer will take;
- whether vested stock options can be sold directly, with the company paying the spread, or must be exercised first.
For how a public company tender offer runs, including withdrawal rights and broker deadlines, see our guide to how tender offers work.
Can you sell private company shares on your own?
Only if your agreements allow it and the company signs off. Most startups restrict transfers in the bylaws or in the stock purchase and option agreements. Typical terms include:
- Company consent. No transfer is valid without board or company approval, and many companies refuse transfers outside organized programs.
- Right of first refusal (ROFR). Before you sell to an outside buyer, you must notify the company of the price and terms. The company, and sometimes major investors, can then buy the shares on the same terms within a set number of days.
- Bans on side deals. Many agreements prohibit forward contracts, pledges or other arrangements that transfer the economics of shares before they can legally move.
- Buyer limits. Companies often limit buyers to existing investors or to accredited investors and may block competitors.
The sale also needs an exemption from SEC registration. Under Rule 144, restricted securities of a company that does not file SEC reports must be held at least one year before resale under that rule. Other private resales rely on separate exemptions, which is why buyers and the company’s lawyers usually set the paperwork, not the seller.
Secondary marketplaces match sellers with buyers, but they still need the company to approve each transfer and waive or exercise its ROFR. A trade that the company does not record on its stock ledger does not transfer the shares.
How is the price set, and why does it differ from the 409A value?
The tender or secondary price is negotiated between the buyer and the company or seller. It is separate from the 409A valuation, which is an appraisal of common stock used to set option exercise prices. Buyers in a tender often pay more than the 409A value, sometimes close to the price of the latest preferred round, because they are buying a stake in a company they expect to grow.
A secondary price can also be lower than the last round. Common stock sits behind preferred stock in a sale or liquidation, and private shares cannot be resold quickly, so outside buyers often ask for a discount.
How is a pre-IPO share sale taxed?
The answer depends on how you got the shares and who buys them. Treatment falls into a few common cases:
| What you sell | Typical tax treatment |
|---|---|
| Shares from an exercised NSO, held over one year after exercise | Long-term capital gain on the amount above your basis (exercise price plus income already reported at exercise) |
| Shares from an exercised ISO, sold within 2 years of grant or 1 year of exercise | Disqualifying disposition: part of the gain is ordinary income, the rest capital gain |
| Vested options sold in a tender without exercising | The spread paid is usually treated as wages and reported on a W-2 |
| Any shares sold to the company or its investors above fair market value | Part of the price may be treated as compensation; the offer documents say how the company plans to report it |
The ISO holding-period rules and the AMT issue are covered in our guide to ISO vs NSO stock options. A tax professional can run the numbers for your grant dates before you elect to sell.
What are the steps to sell in a tender offer?
- Read the offer to purchase, the tax summary and the election form, and note the expiration date and time.
- Check how many shares or vested options are eligible and whether exercise is required first.
- Decide how many to offer, within the per-person cap.
- Submit the election through the platform or administrator named in the offer before the deadline.
- Watch for a proration notice if the offer is oversubscribed.
- Confirm the payment date, the tax withheld and how the sale will appear on your W-2 or Form 1099-B.
Bottom line
Before a secondary sale, ask the company whether a tender is planned in the next year. Many companies decline one-off transfers while they are preparing an organized program, and a tender usually has lower fees and simpler paperwork than a negotiated sale. Whether to sell is a personal decision that depends on your taxes and how concentrated your wealth is in one company.
FAQ
Can former employees sell in a tender offer?
Sometimes. Eligibility is set in each offer, and some companies include former employees while others limit participation to current staff or to people with a minimum tenure.
What does a right of first refusal do to my sale?
It lets the company or named investors step in and buy your shares at the price you negotiated. The sale still happens, only with a different buyer, and the process adds weeks to the timeline.
Can I sell unvested shares?
No. Unvested RSUs and options are not yours to transfer, and agreements almost always bar selling them or pledging their future value.
Do I need to be an accredited investor to sell?
No. Accreditation rules apply to buyers in private offerings, not to sellers. The company may still require the buyer to be accredited before it approves a transfer.
