How much alternative minimum tax (AMT) will I owe exercising Syntiant Corp. ISOs?

Exercising incentive stock options (ISOs) does not create regular income tax, but the bargain element (the fair market value at exercise minus your strike price) counts toward the alternative minimum tax (AMT). The amount depends on the bargain element, your other income, your filing status, and your state. The calculator above models federal and state AMT, the AMT crossover point, and how the credit recovers in later years for your exact Syntiant Corp. figures.

Are Syntiant Corp. shares eligible for QSBS?

They might be. Qualified small business stock (QSBS) under Internal Revenue Code Section 1202 can exclude federal tax on much of the gain when shares were acquired at original issuance from a C-corporation while its gross assets were under $50 million, and held at least five years. Whether your Syntiant Corp. shares qualify turns on when you acquired them and the company's asset size at that time.

For long-term capital gains treatment on the eventual sale, ISO shares need to be held until Apr 30, 2027 (2 years from grant) and at least 1 year from exercise. Tranches sold before either deadline are disqualifying dispositions, taxed as ordinary income on the bargain element. The optimizer accounts for both treatments per tranche based on hold periods at horizon. Want to see the whole picture? Try OptionsAhoy's beta: it optimizes ISOs alongside your entire portfolio, and you pick the goal: Max Value, Max Cash, or Min Total Tax.

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 optimized one grant in isolation. The beta optimizes ISOs alongside your RSUs, NSOs, and stock in one plan.

Last reported secondary-market price: $8.89 per share (as of 2026-10-01). Your own 409A may differ.

Equity grants at Syntiant Corp. typically include incentive stock options (ISOs) and non-qualified stock options (NSOs).

Equity comp at Syntiant Corp.

Pre-IPO RSUs vest only when a time-based service condition and a liquidity event condition are each satisfied, with the IPO satisfying the liquidity event condition within six months of the offering; neither condition alone is sufficient. A tranche of executive RSUs additionally requires achievement of market capitalization milestones between $1.5 billion and $3.5 billion within five years of grant alongside continued service. Named executive officers also hold separate Severance and Change in Control Agreements providing full acceleration of all outstanding equity awards upon termination without cause or for good reason occurring within 30 days before or 12 months after a change in control, creating a double-trigger layer for that executive subset only.
Vesting schedule: RSUs under the 2017 Equity Incentive Plan require satisfaction of both a time-based service condition and a separate liquidity event condition before any RSU vests; if either condition is unmet by the expiration date the RSU is forfeited. A subset of executive RSUs carry an additional market capitalization milestone requirement with thresholds ranging from $1.5 billion to $3.5 billion, both the milestone and the service condition must be met within five years of the grant date..

The calculator works at any Syntiant Corp. valuation: enter your strike, the current 409A FMV, an expected IPO price, or anywhere in between. AMT is triggered on the bargain element (FMV minus strike) when you exercise; the calculator models federal AMT, state AMT, and the multi-year credit-recovery path.

Example: at Syntiant Corp.'s last reported price of $8.89, exercising 5,000 ISOs with a $2.67 strike creates a $31,100 bargain element. For a single filer with $200,000 of taxable income, that adds $248 of federal AMT in the year of exercise under 2026 rules, before any state AMT (CA, CO, CT, MN). The credit recovers in later years when your regular tax exceeds AMT. The calculator above runs your exact figures.
