How Tech Industry Compensation (RSUs, Options, and Bonuses) Impacts California Child Support

Current as of: September 9, 2026 Child Support California
💻
In California, tech compensation like RSUs, stock options, and bonuses are fully counted as income for child support. Courts use the Ostler-Smith formula to automatically award a percentage of future bonuses without needing constant court hearings.

Navigating a divorce or child support case in California's tech hubs-whether you live in San Francisco, San Jose, or Palo Alto-often involves complex compensation packages. Unlike a traditional salaried job, tech employees frequently receive Restricted Stock Units (RSUs), stock options, and performance bonuses. If you or your co-parent work in Silicon Valley, calculating true income for child support can become a heavily contested issue. Under California law, the court takes a broad view of what constitutes income to ensure children share in the standard of living of both parents.

We highly recommend browsing our US Lawyer directory to find an experienced family law attorney in your specific California county. Handling tech compensation requires a deep understanding of corporate equity structures and family law. A local lawyer can help you accurately calculate gross income and ensure that your child support orders are fair and legally sound.

Understanding Cal. Fam. Code § 4058

The foundation of child support calculations in the state is Cal. Fam. Code § 4058. This statute broadly defines annual gross income to include salaries, wages, bonuses, dividends, and any other forms of compensation. For tech employees in Santa Clara or San Mateo counties, family court judges at the local Superior Court interpret this to mean that unvested stock and future bonuses must be accounted for when determining support obligations.

Restricted Stock Units (RSUs) & Vesting Schedules

Restricted Stock Units (RSUs) are a standard part of tech compensation packages. When an employer grants RSUs, they are essentially promising to give the employee shares of company stock on a future vesting date. California courts generally view RSUs as income available for child support at the time they vest, not when they are initially granted.

Valuing Vested RSUs

Once RSUs vest, they have a measurable cash value. Even if the employee chooses not to sell the stock immediately, the court will treat the vested value as income for that month or year. Because vesting schedules can cause income to spike dramatically (for example, a large quarterly vest), calculating an average monthly income over a 12-to-24-month period is a common strategy used by forensic accountants and attorneys.

Stock Options (ISOs vs. NSOs)

Stock options give an employee the right to buy company stock at a set "strike price." Tech companies typically offer either Incentive Stock Options (ISOs) or Non-Qualified Stock Options (NSOs). Both forms carry significant weight in child support calculations, though they are treated slightly differently based on tax implications.

Exercising Options and Income Realization

Unlike RSUs, stock options require the employee to take action (exercising the option). California courts usually consider the difference between the strike price and the fair market value of the stock as income when the options are exercised. If a parent intentionally delays exercising options to artificially lower their income, a judge in the local Superior Court may impute income to them, meaning the court will calculate support as if the options had been exercised.

Handling Severance Packages from Tech Layoffs

With fluctuations in the tech industry, layoffs are an unfortunate reality. When a parent receives a large severance package, how does that impact child support? In California, severance pay is considered income. However, because it is a one-time lump sum designed to replace future wages, judges typically stretch or amortize the severance amount over the period of time it is meant to cover (e.g., six months of severance pay is divided over six months of support calculations).

The Ostler-Smith Bonus Schedule Explained

Tech workers often receive substantial, yet unpredictable, annual or quarterly bonuses. Constantly returning to court to modify child support every time a bonus is paid is expensive and impractical. To solve this, California judges frequently utilize the Ostler-Smith percentage bonus schedule.

How the Formula Works

An Ostler-Smith order sets a base monthly child support amount calculated on the parent's reliable, predictable salary. Then, it creates a tiered percentage table for any additional income over that base amount. If the parent receives a $50,000 performance bonus, they must pay a specific percentage of that bonus (e.g., 10% or 15%) directly to the other parent as additional child support within a certain number of days after receiving it. This ensures the child benefits from the extra income without requiring a new court hearing.

Frequently Asked Questions (FAQ)

What if my RSUs vest but the stock price has dropped significantly?

The court will look at the fair market value of the RSUs on the date they actually vest. If the stock price dropped before vesting, the lower value is what counts as income for child support purposes.

Do I have to report my tech bonuses to my ex-spouse?

Yes. If you have an Ostler-Smith order, you are typically required to provide a year-end pay stub, W-2, or an accounting of all bonuses and stock vesting to the other parent so the percentage can be accurately calculated.

Can the court force me to exercise my stock options?

Generally, a family court judge cannot force you to exercise stock options. However, if they find you are hoarding vested options specifically to avoid paying child support, the judge may impute income to you based on the available value.

How are sign-on bonuses treated in California child support?

A sign-on bonus is considered gross income under California law. Depending on the size of the bonus, a judge may apply an Ostler-Smith percentage to it, or average it into your monthly income over the course of a year.
