After-tax dollars at end of year 3, net of all federal + state taxes through the sale.
This year: exercise 10,000 shares.
= gross gain at sale − federal + state LTCG − AMT premium above baseline regular tax (time-valued)
AMT premium for exercising: $0 (on top of $230,496 regular tax across the horizon)
Exercising everything this year stays under your federal AMT crossover, so no schedule is needed.
Federal AMT crossover this year: 40,731 shares ($41,138 bargain element). Above that, each additional share this year adds federal 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 optimized one grant in isolation. The beta optimizes ISOs alongside your RSUs, NSOs, and stock in one plan.

About dbt Labs
dbt Labs is a privately held Data company, incorporated in Delaware and headquartered in Philadelphia, PA.
Last reported secondary-market price: $6.01 per share (as of 2026-10-27). Your own 409A may differ.
Data transformation; merged into Fivetran (private) 2026-06-01, no longer a separately traded security.
Equity grants at dbt Labs typically include incentive stock options (ISOs) and non-qualified stock options (NSOs).
Tristan Handy, Drew Banin, and Connor McArthur founded dbt Labs in Philadelphia in 2016, growing it out of their consultancy, Fishtown Analytics. dbt (data build tool) lets analysts write SQL to transform raw warehouse data into clean, reusable tables, reaching over 80,000 data teams. dbt Labs raised $222 million in a 2022 Series D at a $4.2 billion valuation, backed by Altimeter, Databricks, and Snowflake. On June 1, 2026, it completed an all-stock merger with data-ingestion company Fivetran, joining a combined business with roughly $600 million in annual recurring revenue (yearly subscription income); it no longer operates independently.

The calculator works at any dbt Labs 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 dbt Labs's last reported price of $6.01, exercising 5,000 ISOs with a $1.8 strike creates a $21,050 bargain element. For a single filer with $200,000 of taxable income, that stays under the federal AMT crossover, so no federal AMT is due under 2026 rules (state AMT in CA, CO, CT, MN can still apply). The calculator above runs your exact figures.

dbt Labs equity questions
- How much alternative minimum tax (AMT) will I owe exercising dbt Labs 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 dbt Labs figures.
- Does dbt Labs grant ISOs, NSOs, or RSUs?
- Equity compensation at dbt Labs typically takes the form of incentive stock options (ISOs) and non-qualified stock options (NSOs). Incentive stock options can trigger the alternative minimum tax (AMT) when you exercise.
- Are dbt Labs 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 dbt Labs shares qualify turns on when you acquired them and the company's asset size at that time.
