Frequently Asked Questions
What is a good ESPP return rate after taxes?
With a 15% discount and immediate sale, expect 10-12% net return after ordinary income tax (32-37% bracket). With lookback provision in rising market (100鈫?20), effective discount reaches 29%, yielding 20-24% net return. Holding for qualifying disposition can improve returns by 5-8% through capital gains treatment, but introduces market risk.
How does the lookback provision work in ESPP?
Lookback uses the lower of grant date or purchase date stock price for calculating your purchase price. Example: Grant date $100, purchase date $120, 15% discount. Your purchase price is $85 (15% off $100), but market value is $120鈥攜ou gain $35/share (41% instant return) instead of $15/share (14% return) without lookback. Most tech companies offer this.
Should I sell ESPP shares immediately or hold for qualifying disposition?
Immediate sale (disqualifying disposition): Guaranteed profit, 10-24% return, simple taxes, zero risk. Hold 2+ years from grant + 1+ year from purchase (qualifying disposition): Potential 5-8% tax savings, but exposes you to stock decline risk. Recommendation: Sell immediately unless company stock has strong fundamentals and you have low concentration risk (<10% net worth in employer stock).
What is the IRS limit for ESPP contributions?
IRS limits ESPP purchases to $25,000 per calendar year based on stock fair market value. With 6-month offering periods, this means $12,500 per period.

If your company allows 15% salary contribution and you earn $200,000, your limit is $25,000 (not $30,000), creating forced diversification.

Tax savings vs disqualifying: 17% 脳 $50 = $8.50/share.
