ESPP Qualifying Disposition Tax Split Calculator
Quantify the tax pieces triggered by a qualifying ESPP sale. Provide the purchase price, market value on the purchase date, and the sale price to see how much ordinary income is recognized, how much remains as capital gain or loss, and what the estimated tax bill looks like at your chosen rates.
Illustrative only. Verify tax classifications with your payroll team and advisor before filing.

FAQ
Does the calculator cover disqualifying dispositions?
No. Disqualifying sales recognize ordinary income up to the entire spread between the sale price and purchase price. Run a separate scenario tailored to those rules.
How should I include state taxes?
Blend your state marginal rates into the ordinary and capital gains percentages or run separate scenarios for federal and state obligations.
Can I use this for alternative minimum tax planning?
ESPP shares do not trigger AMT adjustments like incentive stock options. Use the results here alongside your broader tax projection to confirm withholding needs.
What if my employer withholds on the ordinary income?
Subtract the expected withholding from the estimated tax output to gauge any additional quarterly payments or reserves required.
Additional Information
- Qualifying dispositions meet both the two-year offering and one-year holding periods, so the discount becomes ordinary wage income limited by the gain.
 - Ordinary income cannot exceed the discount between the purchase-date market value and what you paid, even if the sale price is much higher.
 - Capital gain or loss still uses the discounted purchase price as basis; losses can offset other capital gains subject to IRS rules.
