What should I do first with my equity compensation (RSUs, ISOs, NSOs, ESPP)?

Use the assessment to identify your equity type, your main tax risks, and the next best calculator to run for your scenario.

Which calculator should I use for ISO exercise planning?

The assessment routes you to AMT/ISO tools based on whether you’re considering early exercise, same-day sale, or holding shares.

How do I prioritize AMT vs capital gains optimization?

The assessment highlights the dominant driver (AMT exposure, holding periods, or ordinary income) and suggests what to model next.

Do I have a withholding gap on RSU vesting?

The assessment can flag common withholding shortfalls and point you to the RSU estimator to quantify estimated taxes.

What are the common tax mistakes with ESPP sales?

It surfaces double-taxation and qualifying disposition risks and points you to basis-adjustment and holding-period tools.

Is this personalized tax advice?

No—this is an educational triage tool to help you model scenarios and decide what to ask your tax advisor.

How much tax will I owe when my RSUs vest?

Estimate total tax on RSU ordinary income and compare it to expected withholding to spot an underpayment risk.

Is RSU withholding enough (22% / 37% supplemental rate)?

Model your marginal bracket vs standard RSU withholding to see whether you should increase withholding or pay estimated tax.

How do state taxes affect RSU vesting?

Include a state rate to estimate incremental state liability on vest income (rules vary by state and sourcing).

Should I sell RSUs immediately or hold?

RSU vesting is ordinary income either way; the difference is capital gains after vest. Use this plus the capital gains tool to compare.

How do I estimate quarterly taxes for RSUs?

Use the withholding gap estimate as an input to decide whether to make estimated payments (consult your advisor for safe harbor rules).

What numbers do I need for an RSU estimate?

Vesting value, your income context, and a state—then compare owed vs withheld.

How do I avoid double taxation on ESPP shares?

Many brokers report an unadjusted basis on Form 1099‑B. This tool helps compute the adjusted basis for Form 8949 reporting.

Why is my ESPP cost basis wrong on the 1099-B?

Brokers often exclude the compensation element (discount) that is taxed as ordinary income—so you need an adjustment to avoid double tax.

What adjustment do I report on Form 8949 for ESPP?

You generally adjust basis to reflect ordinary income recognized; the tool guides the numbers and the typical reporting approach.

Does qualifying vs disqualifying disposition affect basis adjustment?

Yes—the ordinary income component differs. Pair this with the qualifying disposition calculator to model both outcomes.

Is ESPP discount taxed as capital gains or ordinary income?

It can be ordinary income (and sometimes partly capital gain) depending on disposition type; this tool focuses on correct basis reporting.

What inputs do I need to adjust ESPP basis?

Purchase price/discount, FMV, sale price, and disposition details—then compute the broker-basis correction.

What is the ESPP $25K limit and how is it calculated?

For Section 423 ESPPs, the $25K limit is based on the stock’s fair market value at the offering date (not the purchase date).

How do I know if my ESPP contributions exceed the $25K limit?

Model offering-date FMV, purchase periods, and your payroll deductions to verify compliance.

Does a lookback provision change the $25K limit calculation?

The limit is still determined using offering-date FMV—lookbacks affect purchase price but not the statutory $25K cap input.

What happens if I exceed the ESPP $25K limit?

Your plan/administrator typically caps purchases; exceeding can change qualification treatment depending on plan mechanics.

How should I optimize ESPP contributions across offering periods?

Use the limit check to set a safe payroll deduction level, then use the sale timing tool for after-tax optimization.

What inputs do I need for the $25K ESPP tool?

Offering date, offering-date FMV, purchase schedule, and your intended contribution rate.

Is my ESPP sale a qualifying or disqualifying disposition?

Compare your offering date and purchase date to the sale date to check whether statutory holding periods are satisfied.

How much tax do I save by waiting for a qualifying disposition?

Model both outcomes to estimate the tradeoff between ordinary income and capital gains treatment.

What are the ESPP holding period rules?

Generally, 2 years from the offering date and 1 year from the purchase date (confirm with your plan and jurisdiction).

Does qualifying disposition always mean lower taxes?

Not always—price moves and marginal rates can change the result. This tool helps quantify the scenario.

How does qualifying disposition affect my cost basis?

It changes the ordinary income component; pair with the basis-adjustment calculator for reporting.

What dates do I need to evaluate an ESPP disposition?

Offering date, purchase date, and sale date (plus FMV/price inputs if modeling taxes).

What is the ISO $100K limit?

It’s an annual limit (based on grant-date FMV of shares first exercisable in a year) beyond which options are treated as NSOs.

How do I calculate if my ISOs exceed the $100K limit?

Use vesting schedule, share counts, and grant-date FMV to see which tranches convert to NSOs.

What happens when ISOs exceed the $100K limit?

The excess portion is generally treated as NSOs (different tax timing and withholding).

Does the $100K limit depend on exercise price or FMV?

The statutory calculation uses grant-date FMV, not exercise price or current FMV at exercise.

How does ISO-to-NSO conversion affect AMT and ordinary income?

ISOs can create AMT on exercise; NSOs generally create ordinary income on exercise. Model both with AMT/ISO tools.

What inputs do I need for the ISO $100K calculator?

Grant-date FMV, vesting schedule, and the number of shares that become exercisable each year.

Will exercising ISOs trigger AMT?

Estimate AMT exposure based on the ISO spread (FMV − strike), income, and exemption phaseouts.

How much AMT will I owe if I exercise ISOs?

Model the AMT base and estimate incremental AMT from the exercise spread to understand cash needs.

Is it better to exercise ISOs early to reduce AMT?

Early exercise can reduce spread, but has risks; use this tool to compare scenarios and timing.

How does AMT credit recovery work after ISO AMT?

You may recover AMT as a credit in future years depending on your regular tax vs AMT—this tool includes a high-level view.
