Tech Equity & Digital Asset Advisory

Built for Engineers, Executives & Founders With Complex Equity.

We don't rely on automated 1099-B imports. We reconcile every vest lot against your W-2 and Stock Plan Supplemental Statement so you never pay tax twice.

01

Form 1099-B & Form 8949 Cost-Basis Adjustment

E*TRADE, Fidelity, and Schwab frequently report $0 or unadjusted cost basis in Box 1e for RSU and ESPP sales. We reconcile your Supplemental Information statement and apply the exact Code B/E basis adjustment on Form 8949.

02

Fixing the 22% Supplemental Withholding Trap

Employers withhold only 22% federal tax on RSU vests under $1M, while your true marginal rate is 32%–37% + 0.9% Medicare. We design safe-harbor estimated payment or W-4 schedules to eliminate underpayment penalties.

03

3-Year Prior Return Lookback (Form 1040-X)

Sold RSUs or ESPPs in the last 3 years using TurboTax or a high-volume preparer? We audit your prior Schedules D and Forms 8949 against your brokerage supplemental statements to recover double-paid taxes.

04

ISO Exercise & AMT Crossover Modeling

Before you exercise Incentive Stock Options (ISOs), we model Form 6251 Alternative Minimum Tax (AMT) exposure, calculate your exact AMT-free exercise ceiling, and track Form 8801 AMT credit carryforwards.

05

Multi-State RSU Sourcing Allocation

Moved between CA, NY, WA, TX, IL, or NJ between your grant date and vest date? States tax RSU vests based on workdays spent in-state from grant to vest. We compute precise multi-state allocation schedules and credits.

06

Cryptocurrency, Staking & DeFi Reconciliation

Multi-wallet cost-basis reconstruction (FIFO vs. Specific Identification), wash-sale and tax-loss harvesting analysis, staking/airdrop ordinary income schedules, and defense against IRS 1099-DA / 1099-B mismatches.

Frequently Asked Questions

RSU, ESPP, ISO & Crypto Tax FAQs

How does RSU double taxation happen on E*TRADE, Fidelity, or Charles Schwab 1099-B forms?

When your RSUs vest, the fair market value of the shares is already included as taxable ordinary wages in Box 1 of your W-2. However, for noncovered shares or sell-to-cover transactions, brokerages like E*TRADE, Fidelity, and Charles Schwab often report a $0 or blank cost basis in Box 1e of Form 1099-B. If you or your tax software import that 1099-B without manually adjusting the basis on Form 8949 using the Stock Plan Supplemental Statement, you pay tax on the exact same RSU income twice.

Can I recover overpaid taxes if I paid tax twice on RSUs or ESPPs in the last 3 years?

Yes. Under IRC § 6511, you generally have 3 years from the original filing deadline (including extensions) to file Form 1040-X (Amended U.S. Individual Income Tax Return) to correct unadjusted Form 8949 cost basis and claim a refund plus statutory interest from the IRS and your state tax agency.

Why do I always owe a huge tax bill in April even though my company withholds shares when my RSUs vest?

Under IRS supplemental wage regulations, employers typically withhold a flat 22% federal tax on RSU vests under $1 million in a calendar year. However, tech engineers, product managers, and executives earning $250,000 to $800,000+ actually sit in the 32%, 35%, or 37% marginal federal bracket plus the 0.9% Additional Medicare Tax—creating an automatic 10.9% to 15.9% under-withholding gap on every vest.

How do Qualifying vs. Disqualifying Dispositions work for ESPP shares?

For an Employee Stock Purchase Plan (ESPP) with a 15% discount and lookback provision, selling shares before meeting the holding period (2 years from offering date and 1 year from purchase date) is a Disqualifying Disposition. The bargain element is taxed as ordinary W-2 income, and your Form 8949 cost basis must be stepped up by that exact ordinary income amount so the discount isn't taxed a second time as a capital gain.
