RSU Tax Estimate · 2026

Meta (META) RSU Tax Calculator forCaliforniaEmployees

What's withheld when your META RSUs vest vs. what you actually owe in California, with 2026 federal brackets.

This page estimates the RSU withholding gap for Meta (META) employees who live and work in California. The example is a single filer with a $200,000 salary and a $50,000 vest, using 2026 federal brackets. The estimated result is −$3,105. The table below shows how that changes with salary and vest size. Meta's stock fell steeply in 2022 and recovered strongly afterward. That history is a reminder that the tax on each vest is set by the vest-day price, so the same number of shares can produce very different tax bills from one vest to the next.

Withheld at vest minus actually owed. Negative means you'll owe more when you file; positive means over-withholding. Single filer, no bonus, standard deduction, vest in the second half of the year, 2026 federal brackets. The gap is the same for every company at the same vest value; only the share count differs (100 META shares ≈ $50,000 at an example price of $500).

What this means for Meta employees in California

At a $200,000 salary, extra RSU income is taxed by California at 9.3%. The higher rates only start at roughly $371,000 of taxable income (2025 thresholds; 2026 thresholds are indexed slightly higher), and the 13.3% headline rate includes a 1% surcharge that applies only above $1 million.

California requires employers to withhold 10.23% on stock compensation. That is more than the 9.3% most tech salaries actually owe, so the state side is usually slightly over-withheld. On a $50,000 vest at a $200,000 salary: California withheld $5,115, California owed $4,650 (+$465). The shortfall comes from the federal side: 22% withheld ($11,000) versus $14,570 owed (−$3,570).

California SDI (1.3% in 2026, no wage cap) is also withheld from RSU income: $650 on a $50,000 vest. It is withheld correctly, so it doesn't add to the gap, but it does reduce what you keep.

California taxes RSU income based on where you worked between grant and vest. If you move out of California before a grant finishes vesting, California can still tax the share of each vest that relates to your California workdays.

Frequently asked questions

Q.Does Meta withhold enough California tax on my RSUs?

Usually yes, sometimes slightly more than needed. California's required 10.23% supplemental rate on stock compensation is above the 9.3% bracket that applies to most tech salaries between roughly $73,000 and $371,000 of taxable income. Above roughly $446,000, California's 11.3% rate exceeds the 10.23% withheld and a small state shortfall appears. The larger gap is almost always federal.

Q.If I leave California before my Meta RSUs finish vesting, do I still owe California tax?

Often yes, for part of each vest. California generally allocates RSU income by the workdays you spent in California between the grant date and the vest date, so moving to a no-tax state like Texas or Washington doesn't erase California tax on the portion earned while you worked there.

Q.How can I see exactly what Meta withheld on my vest?

Open the release or vest confirmation in your equity account: it lists the shares released, the vest-day price and the shares sold or withheld for taxes. The pay stub for that pay period breaks the withholding into federal, state, Social Security and Medicare lines. Enter those figures in the calculator to compare them with what you actually owe.
