The AMT credit only recovers in years where regular tax exceeds AMT — typically a year with no ISO exercise. It carries forward indefinitely (Form 8801) and applies in any future tax year where regular tax exceeds AMT.
Estimates only. Excludes disqualifying dispositions, NSOs, multi-state moves, and AMT preferences other than ISO bargain elements. Long-term capital gains tax assumes a qualifying disposition (ISO held ≥1 yr from exercise and ≥2 yr from grant); state LTCG follows ordinary brackets except where the state grants preferential treatment (HI, ND, SC, WI, AR, NM) or has a dedicated LTCG-only tax (WA). Assumes you are within the $100K ISO limit (any portion of an annual ISO grant whose FMV at grant exceeds $100K is treated as NSO from the start, §422(d)). State AMT figures are 2025 (next-year values published in late 2026). Not financial advice.
QSBS note. If your shares qualify (typically pre-IPO C-corp grants held 5+ years), a federal rule lets you exclude up to $10M of gain on a future sale from federal tax. That single rule shifts exercise-timing math more than AMT does. (This is §1202 “qualified small-business stock”.) Modeled in beta, not here.
You solved the exercise window. The beta plans what comes after it: the new shares, your remaining equity, hedges, and taxes in one multi-year plan.

Equity comp at Liftoff Mobile, Inc.
- RSUs use double-trigger vesting. Two things must both happen before the shares are yours: (1) the normal time-based vesting completes, and (2) the company has a liquidity event (an IPO or an acquisition). Until both happen, you do not yet own the shares and you do not owe tax on them.

If you have left Liftoff Mobile, Inc. (LFTO) with vested incentive stock options (ISOs), most stock plans give you 90 days from your departure date to exercise or forfeit them. Exercising everything at once concentrates the AMT bargain element into a single tax year. This calculator computes your window deadline from your departure date, the alternative minimum tax (AMT) cost of a full exercise at the current trading price, and the partial-exercise share count that maximizes expected after-tax value.
Example: leaving Liftoff Mobile, Inc. (LFTO) with 5,000 vested ISOs at a $6.64 strike, with the last close at $22.14, exercising all of them inside the 90-day window puts a $77,500 bargain element into one tax year. Above the 2026 federal AMT exemption ($88,100 single, $137,000 married joint), the 28% AMT rate adds roughly $21,700 on top of regular tax before any state AMT (CA, CO, CT, MN). Exercising fewer shares lowers that bill at the cost of forfeiting the rest; the calculator above finds the count that maximizes expected after-tax value for your exact figures.

Liftoff Mobile, Inc. equity questions
- I left Liftoff Mobile, Inc.. How long do I have to exercise my ISOs?
- Most stock plans give you 90 days from your departure date to exercise vested incentive stock options (ISOs); unexercised options are forfeited when the window closes. Tax law is slightly wider: ISO treatment requires you to have been an employee within 3 months of exercise (Internal Revenue Code Section 422(a)(2)), so options exercised under an employer-extended window are taxed as non-qualified stock options (NSOs). Check your grant agreement for Liftoff Mobile, Inc.'s exact terms. The calculator above computes your deadline from your departure date, the alternative minimum tax (AMT) cost of exercising, and the share count that maximizes after-tax value.
- Does Liftoff Mobile, Inc. grant ISOs, NSOs, or RSUs?
- Equity compensation at Liftoff Mobile, Inc. typically takes the form of incentive stock options (ISOs), non-qualified stock options (NSOs), and restricted stock units (RSUs). Incentive stock options can trigger the alternative minimum tax (AMT) when you exercise. Restricted stock units are taxed as ordinary income when they vest.
- When did the Liftoff Mobile, Inc. IPO lockup expire?
- Liftoff Mobile, Inc. (LFTO) went public on June 4, 2026. The standard post-IPO lockup runs 180 days, so employee and insider shares generally became sellable around December 1, 2026. Confirm against your own grant paperwork, since some lockups release early or in stages.
- Do Liftoff Mobile, Inc. RSUs use double-trigger vesting?
- Yes. Liftoff Mobile, Inc. restricted stock units (RSUs) vest only when two things both happen: the time-based schedule completes, and the company has a liquidity event such as an initial public offering (IPO) or an acquisition. Until both occur you do not own the shares and owe no tax on them.
