For most employees, the answer to what to do at IPO lockup expiration is to sell part of the released RSU shares first, Edward Jones Investments advises, since their tax was largely paid at release. Quick test: in the first open window, sell whatever you'll need within 3 years plus your April tax shortfall. Holding a full year for long-term rates only saves tax on the gain since release, and a small price drop can erase that saving. Two readers get opposite answers. An engineer renting with a down payment due in 3 years should sell a large block right away. An engineer with no near-term cash need and a paid-off home can stage sales over several windows, because nothing forces a sale into one week.
At Edward Jones Investments, advisors start with the cash you can't afford to lose, size that sale first, and only then decide how much of the remaining stock your spending can absorb falling. This article follows Lan, a hypothetical engineer, through her lockup end. It covers the tax side only: what lowers the bill, what merely moves it, and what the IRS rules actually let you do. Every investment carries the risk of loss, including the money originally invested, and that includes shares you decide to keep.

Day 181 is often not a sell day. Get your insider policy's trading window calendar before you plan anything around the lockup date.

If the house is 3 years away, that down payment has zero room to fall. We size that sale first, and only then talk about the shares you can afford to keep.

Withholding on RSUs at 22% leaves a 13-point gap for anyone in a 35% bracket. On $560,000 of release value, that's $72,800 due in April.

Which dates fall between lockup end and your first open trading window?
Your lockup usually ends about 180 days after the IPO, but your first sale date is the first open trading window under your company's insider policy, typically 1 to 2 trading days after the next earnings release. A Rule 10b5-1 plan can sell outside windows, after a cooling-off period of 30 days for most employees.
Lan, our hypothetical engineer, hit day 181 and found she still couldn't sell. A lockup is a contract between the company, its underwriters and shareholders, not a law, so the exact end date and any early release tied to earnings or share price sit in the lockup agreement. Her company's insider policy added its own blackout on top of that.
A 10b5-1 plan lets you sell on a preset schedule, but you must adopt it while you hold no material nonpublic information. The cooling-off period is longer for officers and directors. A plan set up the week the lockup ends won't trade on day one, so it's a tool for the second and third sales, not the first. Before the first trade, get answers to these four questions:
- Plan administrator: what is my exact lockup end date, and does any early release apply?
- Plan administrator: am I a designated insider with extra pre-clearance rules?
- CPA: how much was withheld at release, and what estimated payment reaches the 110% prior-year safe harbor?
- Advisor: how many shares cover the down payment and the tax gap?
Which IPO shares already paid tax through your W-2?
Shares from RSUs that released at the IPO and NSOs you already exercised were taxed as wages, so only the gain since release or exercise is taxed when you sell. ISO shares and unexercised options carry the hidden tax, which is why they come last or need a CPA's numbers.
Lan's first surprise was that most of the tax on her stock was already on her W-2. The release value became her cost basis, so a sale at lockup only taxes the move since release. That makes RSU lots the cheap ones to sell.
The row to watch is lots trading below basis. A loss there offsets gains from the RSU sale, but the IRS wash sale rule kicks in if more RSUs vest in the 30 days on either end of the sale, before it or after it.
| Account or lot | How it is taxed | What to do with it |
|---|---|---|
| RSU shares released at IPO | Wages at release; gain after | Sell first; little extra tax |
| NSO shares exercised earlier | Spread was wages; basis set | Sell highest-basis lots next |
| ISO shares, under 1 year | Disqualifying sale: spread is wages | Wait or get CPA math |
| Lots below cost basis | Loss offsets gains | Sell; check 30-day vesting |
| Unexercised vested options | No tax until exercise | Note expiry; don't exercise blindly |
Sell the released RSU lots first: Lan's day-one numbers
Lan, age 39, holds 8,000 RSU shares that released at the IPO at $70, so $560,000 went on her W-2 and $70 became her basis (hypothetical, round numbers). She and her husband Raj, age 41, rent with two kids under 8. Of the family's $2 million net worth, about $1.4 million sits in employer stock. They want a $400,000 down payment in 3 years. On her first open day the stock is $80, and this example follows only Lan's own RSU lots.
Selling 5,000 shares raises $400,000. The gain is 5,000 × $10 = $50,000, short-term, so the tax is $17,500 at an assumed 35% rate. Long-term treatment needs more than 1 year after release, about 6 more months here. At an assumed 15% rate the tax would be $7,500, a $10,000 saving. But a $2 drop per share (2.5% of $80) on 5,000 shares costs the same $10,000.
Withholding is a separate cash need. Her company withheld 22% while her assumed rate is 35%, so 13% × $560,000 = $72,800 is owed in April. Add the $400,000 down payment and the $17,500 sale tax and the total is $490,300. At $80, Lan sells about 6,130 shares, which raises $490,400. The extra 1,130 shares add a little tax, so a CPA should refine the figure. Our calculator on this site runs the same arithmetic with your own lots.
Before Edward Jones Investments sizes Lan's sale, it marks the down payment and the April bill as money with zero room to fall, because the house is 3 years away. Only the shares left after that, her remaining roughly 1,870 plus Raj's stake, are sized by how big a drop the family's spending playbook can absorb. Any shares kept can lose value, including what was paid for them.
The long-term holding comparison
The withholding gap as its own cash need
Quick test: if you'll need money from the stock within 3 years (a down payment, the April tax gap), sell that amount in the first open window, RSU lots first.
| Measure | Sell at $80 now | Hold about 6 months |
|---|---|---|
| Shares sold | 5,000 | 5,000 |
| Gain per share | $10 | $10 if price holds |
| Assumed tax rate | 35% | 15% |
| Tax on $50,000 gain | $17,500 | $7,500 |
| Exposure to a price drop | None | About 6 months |
Test four lockup beliefs against the IRS rules
"Selling right away means a huge tax bill." For RSU shares the ordinary income tax was set at release, and only the gain since release is taxed at sale. In Lan's case that's $50,000 of gain on $400,000 of proceeds, a bit over 12% of what she sells.
"Hold a year and it all becomes long-term." Only the gain after release or exercise qualifies. ISO shares need 2 years from grant and 1 year from exercise before a sale counts as qualifying, and a sale that misses either test turns the spread into wages.
"The stock always dips at lockup, so wait a few weeks." No reliable pattern exists, and waiting is a bet on a single stock. If you wait on money you need for a house, you've made that bet with the down payment.
"A loss sale always saves tax." After offsetting gains, net losses cut only $3,000 of ordinary income a year, and new RSU vesting within 30 days can trigger the wash sale rule. The IRS reports these on Form 8949, so the lot detail matters.
Watch for the withholding gap and the wrong-lot sale
Two small errors tend to arrive together. Trusting the 22% withholding is one. Selling ISO shares exercised less than a year ago before the RSU lots is the other, and it makes the sale a disqualifying disposition. For illustration, 2,000 ISO shares exercised at $5 and sold at $80 turn a $150,000 spread into ordinary income, about $30,000 more tax at an assumed 35% versus 15%. That lands beside a $72,800 April bill nobody set cash aside for, plus a possible underpayment penalty if the 110% prior-year safe harbor wasn't met.
Work through IPO lockup expiration day in this order
Start by getting the lockup end date and the window calendar from the stock plan administrator. Next, download the lot list with release date, share count and basis per lot. Then estimate the April gap as release wages × (your rate minus the rate withheld). Lan's was $560,000 × 13%, or $72,800.
Add that gap to the cash you need within 3 years. The total is your first sale. Place limit orders on the RSU lots using specific lot identification, not the broker's default, which may pick shares you didn't intend. Move the proceeds to a separate account for the down payment, and pay the estimated tax by the next quarterly due date.
Save the broker's supplemental basis statement. Form 1099-B often shows RSU basis as $0 or leaves it blank, and filing it that way taxes the same income twice. Finally, size the rest by risk capacity: staged sales over the next 2 to 4 windows, or a 10b5-1 plan once you're clear of inside information. Staging spreads the price risk, though it doesn't lower the tax on each lot.
Steps before the first order
Steps after the sale
What if the stock, the tax law or your job changes after you sell?
If the stock rises, falls or your job ends after you sell, the money you sold was never at risk, so the sale holds up. Keep about 6 months of spending in cash apart from the down payment fund, and re-check any later sale against the tax rules in force then.
If the stock climbs after Lan sells, the sold portion was money she couldn't risk, so regret doesn't change the math. Putting the remaining shares on a written sale schedule limits second-guessing. If the kept shares fall, or a layoff ends future vesting, that cash cushion means she never sells in a bad week.
Capital gains rates and wash sale rules can be amended. Selling the tax-cheap RSU lots now uses today's rules for the cash you need. For the rest, Edward Jones Investments re-checks each later sale against the rules then in force.
Decide what you handle alone and what goes to Edward Jones Investments
You can pull the lot list, find your window dates and run the withholding-gap arithmetic yourself tonight. The sale size, the order of ISO, NSO and RSU lots, and how much of the rest your family's spending can afford to see fall are worth a conversation with Edward Jones Investments. The fee is discussed openly in the first call and confirmed in writing before any work starts. If most of your stake is ISO shares exercised before the IPO, have a CPA run the numbers before any trade.
Holding a full year for long-term rates only saves tax on the gain since release, and a small price drop can erase that saving.
What people ask about an ipo lockup expiration what to do
How much will I owe in April if my company withheld only 22% on RSUs that released at the IPO?
You owe the gap between your actual rate and 22%, applied to the release value. At an assumed 35% rate on $560,000 of released shares, that's 13% × $560,000 = $72,800. Estimated payments or the 110% prior-year safe harbor can limit penalties; check with a CPA.
Can I deduct a loss on company shares if more of my RSUs vest next month?
Possibly not. Under the IRS wash sale rule, a loss is disallowed when you acquire substantially identical shares within 30 days of the sale, whether before it or after it, and an RSU vest counts as an acquisition. You don't lose the deduction for good: the disallowed amount raises the cost basis of the newly vested shares, so you claim it later when you sell them.
Can I exercise my stock options during the lockup and sell the shares after it ends?
Often yes, if your plan and insider policy allow it, but exercising costs cash and may trigger tax before you can sell. NSO exercise creates wages immediately. ISO exercise can raise AMT exposure. Confirm the rules with your plan administrator and run the numbers with a CPA first.
Is a 10b5-1 plan worth setting up after the lockup if I'm not an executive?
Usually yes, if you expect to hold inside information during blackout periods and want sales on a schedule. Most employees face a 30-day cooling-off period before the first trade. It won't help your day-one sale, but it can handle later staged sales without window timing.
My wife's company just went public; should we sell her shares before we buy a house?
Sell the part you need for the down payment and the April tax gap, because that money has no room to fall. Check how her lots were taxed first: RSU lots are cheap to sell, ISO lots may not be. Keep the rest on a written sale schedule.
