Financial Planning for Meta Employees: RSUs, 401(k), and the Mega Backdoor Roth

Meta pays a large share of compensation in equity, and the plan is one of the more generous in tech once you use every piece. The items below are where planning makes the difference. Confirm current details with Meta's benefits team, since plans change.
Meta RSUs vest quarterly over four years with no one-year cliff, so a grant breaks into sixteen roughly equal quarterly vests. Refresher grants are issued during the annual review cycle, usually in February, with their first vest in the May window. The result is a steady stream of vesting events rather than one annual cliff.
Each vest is taxed as ordinary income at the share value on the vest date, added to your W-2. Meta withholds federal tax at the supplemental rate, 22% up to $1 million and 37% above, plus state tax and FICA. If your marginal rate is higher than 22%, set aside the difference so the gap does not surprise you in April.
Meta matches 100% of your contributions up to $12,250 in 2026, and both your contributions and the match vest immediately. Contribute at least enough to capture the full match, since it is an immediate return on your money.
Meta allows after-tax 401(k) contributions with automatic daily in-plan Roth conversions, the mega backdoor Roth. With the 2026 total 401(k) limit of $72,000, after your $24,500 deferral and Meta's $12,250 match, you can add roughly $35,250 in after-tax contributions that convert to Roth. For a high earner, this is one of the most valuable features in the plan.
With a qualifying high-deductible plan, an HSA carries a triple tax advantage. The 2026 limits are $4,400 for individual and $8,750 for family coverage. Routing some RSU proceeds here puts the cash to efficient use.
Concentration is the main risk. Quarterly vesting can build a large position in Meta stock, and selling can feel like betting against your own team. A preset diversification plan keeps the decision steady instead of emotional.
