Private-Company Tender Offers: Terms, Taxes, and Which Shares to Sell

A tender offer lets private-company holders sell some shares at a fixed price. The terms, share type, and holding periods decide what you keep after tax.

Private-Company Tender Offers: Terms, Taxes, and Which Shares to Sell

1 / 8

What is a private-company tender offer?

  • It is a time-limited offer, from the company or outside investors, to buy shares from current holders at one fixed price.
  • For many private-company employees, it is the only chance to sell before an IPO or acquisition, and participation is voluntary.
  • SEC Regulation 14E generally requires a tender offer to stay open at least 20 business days.
  • Since April 2026, an SEC exemptive order lets a private company buying its own shares for cash run as few as 10 business days, if conditions are met.

What is a private-company tender offer?

  • It is a time-limited offer, from the company or outside investors, to buy shares from current holders at one fixed price.
  • For many private-company employees, it is the only chance to sell before an IPO or acquisition, and participation is voluntary.
  • SEC Regulation 14E generally requires a tender offer to stay open at least 20 business days.
  • Since April 2026, an SEC exemptive order lets a private company buying its own shares for cash run as few as 10 business days, if conditions are met.

Why companies run tender offers

  • To give employees some liquidity while the company stays private longer.
  • To let new or existing investors increase their ownership without a new primary round.
  • To help employees cover exercise costs or taxes on equity they cannot otherwise sell.
  • To support retention by showing that equity can turn into cash before an exit.

What should you check in the offer documents?

  • The buyer: a company repurchase and a purchase by outside investors can carry different tax and QSBS consequences.
  • Eligible securities: vested shares only, vested options exercised and sold in one step, and sometimes settled RSUs.
  • Caps and proration: the most each holder may sell, and how sales are cut back pro rata if more shares are tendered than the buyer will take.
  • Dates and withdrawal rights: the expiration date, whether you can withdraw a tender before it, and the settlement date, which sets the tax year.
  • Price and disclosure: how the price compares with the latest 409A value and preferred price, plus the risk factors and financial information provided.

Taxes by share type

  • RSU shares: the vest-date value was already taxed as wages, so the sale is a capital gain or loss from that value, long-term if held over a year.
  • NSOs exercised and sold in the offer: the spread is wage income subject to withholding and payroll taxes, with little added capital gain.
  • ISO shares sold within two years of grant or one year of exercise: ordinary income on the lesser of the exercise spread or the actual gain, without payroll tax.
  • Shares meeting all holding periods: long-term gain, taxed for 2026 at 0% up to $49,450 single or $98,900 joint taxable income, 15% up to $545,500 or $613,700, then 20%.
  • California taxes capital gains as ordinary income, so the long-term rate advantage there is federal only.

Can part of the price be taxed as compensation?

  • When the company, or a buyer connected to it, pays employees more than fair market value, the excess may be treated as compensation rather than sale proceeds.
  • That portion can carry ordinary income tax and payroll taxes, even on shares held for years.
  • Check how the offer documents say any premium will be reported, since that drives withholding and how the sale appears on your return.
  • Settling this question with a CPA before tendering changes the after-tax comparison, especially for long-held shares.

Which lots make sense to sell first?

  • Higher-basis and already long-term lots generally produce less tax per dollar raised.
  • ISO shares that have met both holding periods avoid ordinary income, and selling them can help recover AMT credit from earlier exercises.
  • Shares that may qualify for QSBS lose the exclusion if sold early: stock issued after July 4, 2025 needs three to five years, and older stock five.
  • Section 1202 can disqualify stock issued near certain company buybacks, so a company-run offer is worth a QSBS review even for shares you keep.
  • The offer's administrator sets which lots you can designate, so confirm lot selection before you submit.

After the sale settles

  • Withholding often covers only part of the tax, so estimated payments may be due; the prior-year safe harbor is 110% of last year's tax if AGI exceeded $150,000.
  • The annualized income installment method can match estimated payments to a sale that settles late in the year.
  • The 3.8% net investment income tax can apply to gains once modified AGI exceeds $200,000 single or $250,000 joint.
  • Keeping the offer documents, trade confirmations, and exercise records supports cost basis reporting on Form 8949.
  • Deciding in advance where the proceeds will go keeps cash from sitting idle or being spent by default.

Key takeaways

  • Read who is buying, what is eligible, the caps, and the dates before deciding.
  • After-tax proceeds depend on share type, holding periods, and whether any premium is compensation.
  • QSBS holding periods and company buybacks can change which lots to sell and which to keep.
  • How much to sell is a separate question, covered in the tender offer decision framework; confirm taxes with a CPA, since Rubric does not prepare tax returns.
