You do not enter Form 3922 anywhere on your tax return, and receiving one does not create a tax bill for the year it arrives. Reporting Form 3922 on taxes is not something you do directly; the form is an informational record your employer files with the IRS when shares from a qualified Employee Stock Purchase Plan are transferred into your name.1Internal Revenue Service. About Form 3922, Transfer of Stock Acquired Through An Employee Stock Purchase Plan Under Section 423(c) The numbers on it matter later, in the year you sell those shares, when they drive the calculation of ordinary income and capital gain. Keep every copy.
What the Form Contains and Why It Matters Later
Your employer or its designated broker generates a Form 3922 each time you buy shares through a qualified ESPP. Six data points appear on the form:
- The grant date (also called the offering date), when your employer first offered you the option to buy at a discount.
- The transfer date, meaning the actual purchase date when the shares landed in your account.
- Fair market value of the stock on the grant date.
- Fair market value on the transfer date.
- The discounted purchase price you actually paid per share.
- The number of shares transferred.
The gap between your discounted price and the stock’s fair market value is where your future tax liability lives. When you sell, that gap splits into ordinary income and capital gain, and the split depends on how long you held the shares and which fair market value applies.
Keep Every Form 3922 Until You Sell
The IRS instructs you on the face of Form 3922 to keep it and use it to calculate gain or loss when you sell.2Internal Revenue Service. Form 3922 (Rev. April 2025) Broker records alone are not enough. On Form 1099-B, brokers typically report only the discounted purchase price as your cost basis; they do not add in the compensation income you will recognize on the sale. If you throw the form away and rely solely on the 1099-B, you can end up taxed on the same discount twice — once as ordinary income through your W-2 and again as capital gain through an understated basis.
Hold each Form 3922 at least until you sell the corresponding shares, file the return for that year, and clear the standard three-year retention window after filing. If you participate across many purchase periods, that stack builds up fast. A simple spreadsheet listing each lot’s grant date, purchase date, purchase price, and both fair market values will save real trouble at tax time.
The Numbers Come Into Play When You Sell
The tax treatment of an ESPP sale hinges on two dates printed on Form 3922: the grant date and the purchase date. Meeting the statutory holding periods produces a qualifying disposition and better rates. Missing them produces a disqualifying disposition and more ordinary income.
Qualifying Disposition
To qualify, you must hold the shares more than two years after the grant date and more than one year after the purchase date.3Office of the Law Revision Counsel. 26 USC 423 – Employee Stock Purchase Plans Both clocks have to run out. Because the grant date is earlier, the two-year rule is usually the binding one.
When both periods are satisfied, the ordinary income you recognize is the lesser of your actual profit on the sale or the discount measured from the grant-date fair market value (that value minus your purchase price).4Internal Revenue Service. Stocks (Options, Splits, Traders) 5 Anything above that ordinary income amount is a long-term capital gain.
Disqualifying Disposition
Sell before either holding period is met and the disposition is disqualifying. This includes a same-day sale. The ordinary income is the difference between the fair market value on the purchase date and the price you paid.5Office of the Law Revision Counsel. 26 USC 421 – General Rules That figure is usually larger than a qualifying disposition would produce, because it uses the purchase-date value rather than the grant-date value, and the stock has often risen during the offering period.
Any additional gain above that ordinary income figure is a capital gain, short-term if the shares were held one year or less from the purchase date and long-term otherwise. The ordinary income piece is locked to the purchase-date spread no matter what the stock does afterward.
How the Sale Actually Gets Reported
Three documents come into play in the year of sale: your W-2, your Form 1099-B, and Form 8949.
The ordinary income portion appears in Box 1 of your W-2 for the year of sale. Your employer tracks dispositions and reports this compensation for current and former employees alike. One detail catches many people off guard: no income tax is withheld on this amount.3Office of the Law Revision Counsel. 26 USC 423 – Employee Stock Purchase Plans You may owe a lump sum at filing, and if the amount is large you may need estimated payments to avoid an underpayment penalty.
Your broker sends a Form 1099-B showing sale proceeds and cost basis. For ESPP shares, the basis reported is typically just the discounted purchase price. That understates your real basis by the amount of compensation income already on your W-2, and if you copy the 1099-B numbers straight onto your return, you will pay tax on the discount twice.
The fix happens on Form 8949, which reconciles the broker’s figures with your actual taxable gain and feeds into Schedule D.6Internal Revenue Service. About Form 8949 Enter the sale proceeds in column (d) as reported. Enter the 1099-B cost basis in column (e). Put code “B” in column (f) to flag that the reported basis is incorrect.7Internal Revenue Service. Instructions for Form 8949 Then in column (g), enter the ordinary income amount as a negative number, which raises your basis and reduces the capital gain.
A short example: if the 1099-B shows $15,000 proceeds and $10,000 basis, and $2,000 of the implied $5,000 gain is already on your W-2 as ordinary income, code “B” with a negative $2,000 adjustment brings your capital gain down to $3,000. The total tax owed is the same; the split is now correctly divided between ordinary income and the lower capital gains rate.
Selling at a Loss and the Wash Sale Trap
ESPP shares can drop below your purchase price, and the disposition type controls the outcome. In a qualifying disposition, ordinary income is the lesser of actual gain or the grant-date discount, so if you sell at a loss, actual gain is zero, ordinary income is zero, and the shortfall is a capital loss. Clean result.
A disqualifying disposition is harsher. Ordinary income is fixed at the purchase-date spread regardless of what the stock does next. If the price falls below the purchase-date fair market value, you can owe ordinary income on the discount and claim a capital loss on the decline at the same time.
Capital losses offset capital gains dollar for dollar. Excess losses deduct up to $3,000 against ordinary income ($1,500 if married filing separately), with the rest carried to future years.8Office of the Law Revision Counsel. 26 USC 1211 – Limitation on Capital Losses
Watch the wash sale rule closely. It disallows a capital loss if you buy substantially identical stock within 30 days before or after the sale. ESPP purchases run on a fixed plan schedule, and monthly or quarterly plans routinely put a purchase inside that 30-day window. When that happens, the loss is disallowed for the current year; it gets added to the basis of the newly purchased shares and deducted later. Before selling ESPP shares at a loss, check the next scheduled purchase date. Tax software does not always flag this interaction on its own.
