What is the ESPP Tax Calculator?
The ESPP Tax Calculator helps estimate taxes when selling shares acquired via an Employee Stock Purchase Plan. It models ordinary income from the plan discount and potential capital gains depending on whether your sale is a qualified or non-qualified disposition.
This simplified tool assumes a section 423-qualified ESPP and basic holding test toggle. It does not account for lookback specifics, AMT, state taxes, wash sales, or other complexities.
How to use this calculator

- 2Enter sale price and rates — Add expected sale price, ordinary income rate and long-term capital gains rate.
- 3Set holding status — Toggle qualified disposition if 1-year from purchase and 2-year from offering are met.
- 4Review results — See ordinary income, capital gains and estimated taxes.
Formula & example
Ordinary Income = Discount (qualified: min(discount, gain); non-qualified: full discount); Capital Gains = max(0, Sale Price − Basis); Total Tax = Ordinary Tax + Capital Gains Tax
Example (2026):
- Shares: 1,000; Purchase: $17; FMV at Purchase: $20; Sale: $28
- Discount per share: $3; Ordinary rate: 35%; LTCG rate: 15%
Qualified: Ordinary income = min($3, $11) = $3,000; Capital gains = $8,000; Tax = $1,050 + $1,200 = $2,250
Non-qualified: Ordinary income = $3,000; Capital gains = $8,000; Tax = $1,050 + $1,200 = $2,250

Frequently asked questions
What is an ESPP?+
An Employee Stock Purchase Plan (ESPP) lets employees buy company stock, often at a discount (up to 15%). Section 423-qualified plans can receive favorable tax treatment if holding requirements are met.
How is ESPP taxed?+
Generally, the discount is ordinary income. For qualified dispositions, ordinary income is typically capped and some growth can be long-term capital gains. Non-qualified dispositions recognize the full discount as ordinary income, with any additional gain as capital gains.
What are qualified disposition rules?+
A qualified disposition usually requires holding shares at least 1 year from purchase and 2 years from the offering/grant date. If not met, it's a non-qualified disposition.
