ESPP LEARNING TOOLS

Explore three ESPP rules with the facts in front of you.

Use these focused tools to understand federal §423 holding-period timing, lookback purchase-price math, and one-offering §423-limit mechanics. Each explains one rule, keeps entered values in your browser, and does not determine your tax outcome.

ESPP DATE TOOL

Find when both §423 holding periods have elapsed

Enter offering/grant and purchase/transfer dates to find the earliest date when both federal timing periods have elapsed.

Check the holding-period date

ESPP PURCHASE-PRICE TOOL

See how an ESPP lookback changes the purchase price

Compare illustrative per-share purchase prices with and without a lookback using the same offering-start FMV, purchase-date FMV, and plan discount.

Compare lookback pricing

ESPP $25K LIMIT TOOL

Check one offering’s remaining §423 stock-value capacity

Use employer-supplied starting availability, grant-FMV value already purchased, enrollment/grant FMV, and plan facts to calculate one offering only. No $25,000 default is assumed.
