Stock Compensation and Equity Tax Planning in California

Understand the tax cost before you exercise, vest, sell, or hold company stock.

RSUs, incentive stock options, nonqualified stock options, employee stock purchase plans, and concentrated stock can create income tax, capital-gain, alternative minimum tax, withholding, and estimated-tax questions. JH Group CPA, A Professional Corporation helps executives, founders, employees, and business owners compare the tax and cash-flow consequences before acting.

The tax result may depend on the type of award, vesting date, exercise date, sale date, fair market value, holding period, withholding, state residency, and the documents issued by the employer. A decision made today may affect both the current return and a later stock sale.

Planning Areas We Review

Restricted Stock Units

We review vesting income, payroll withholding, share sales, cost basis, estimated taxes, and the risk of holding a concentrated position after vesting.

Incentive Stock Options

An ISO exercise may create an alternative minimum tax adjustment even when the shares are not sold. We help model exercise size, AMT exposure, available cash, holding periods, and sale scenarios.

Nonqualified Stock Options

Nonqualified options can create compensation income when exercised and capital gain or loss when the acquired shares are later sold. We help reconcile payroll reporting, basis, and the planned sale.

Employee Stock Purchase Plans

ESPP reporting can change depending on the plan and the timing of the sale. We review the purchase records, Form 3922 when applicable, holding periods, ordinary income, and basis reporting.

Concentrated Stock and Planned Sales

We coordinate tax-lot information, expected gains, estimated payments, charitable-giving questions, and sale timing with the client's investment and financial advisers. JH Group CPA does not provide investment recommendations unless separately authorized and properly scoped.

How the Process Works

1. Identify the Decision and Deadline

We confirm the award type, vesting or exercise window, expected sale, state connections, and the decision that must be made.

2. Upload the Records Securely

After engagement, clients upload award agreements, vesting schedules, Forms W-2, 3921, and 3922, brokerage records, paystubs, prior returns, and projected income through TaxDome.

3. Compare Scenarios

We model the agreed alternatives and explain the tax, cash, withholding, and documentation consequences.

4. Complete the Next Steps

Depending on scope, the client receives a tax projection, payment recommendations, open questions, and a written action list.

Frequently Asked Questions

Are RSUs taxed when they are granted?

RSUs are generally not taxed merely when granted. Tax timing depends on the award terms and when the units vest or settle. The employer's plan documents and payroll reporting should be reviewed before reaching a conclusion.

Can exercising an ISO create tax before I sell the shares?

Yes. An ISO exercise may create an AMT adjustment based on the spread between fair market value and the exercise price. The result depends on the facts, including whether the shares are sold in the same year.

Why can stock-sale basis be wrong on a tax form?

Broker reporting may not reflect compensation income already included through payroll. The award, payroll, exercise, and brokerage records should be reconciled to avoid reporting the same economic income incorrectly.

When should I request a review?

Request a review before an exercise, large vesting event, planned sale, job change, move between states, or year-end. Earlier review gives more time to model the tax and arrange cash for payments.
