Vesting Schedule

Vesting turns a conditional benefit into property you own. The condition is usually time: stay employed for a set number of years or months. Some schedules add performance goals, such as revenue targets or share-price levels, or an event such as an acquisition.

The two basic shapes are cliff and graded. Under cliff vesting, nothing vests until a set date, then everything that has built up vests at once. Under graded vesting, a percentage vests at each step, such as 20% a year. Equity grants often combine them: a one-year cliff, then monthly or quarterly vesting for the rest of a four-year term.

Acceleration clauses can speed things up. Single-trigger acceleration vests awards when the company is sold. Double-trigger acceleration needs both a sale and the loss of your job, or a similar change, within a set period afterward. Your plan document or grant agreement defines every term, including how partial periods count, so read it rather than relying on the headline schedule.

Vesting doesn’t always mean access. Vested 401(k) money still follows the plan’s withdrawal rules, and vested stock options still have to be exercised before you own any shares.

Federal law caps how slowly employer retirement contributions can vest. In a defined contribution plan such as a 401(k), employer money must be fully vested after 3 years of service on a cliff schedule, or follow a graded schedule that starts by year 2 and reaches 100% by year 6. A defined benefit pension may use a 5-year cliff or a 3-to-7-year graded schedule, though cash balance and other hybrid pensions must vest fully after 3 years. Plans can always vest faster, and some vest the 401(k) match immediately.

Some money is always 100% vested: your own salary deferrals, all contributions to SEP and SIMPLE IRAs, and the employer contributions in a traditional safe harbor 401(k). Everyone must also become fully vested on reaching the plan’s normal retirement age or if the plan is terminated.

A year of service is defined by the plan, generally 1,000 hours of work in a 12-month period, and a plan may count by calendar year, plan year or anniversary of hire. Unvested amounts are normally forfeited when you leave and are paid your balance, or after five straight years in which you work 500 hours or fewer. If you return to the same employer, earlier service may still count.

Equity awards vest on their own schedules, and the tax event depends on the type. RSUs are taxed as wages when each tranche vests and settles, so their vesting schedule is also a tax calendar. Restricted stock is taxed as it vests too, unless you file a section 83(b) election within 30 days of receiving the shares, which moves the tax to the grant date at the grant-date value. Later growth is then capital gain, but if you forfeit the shares, your deductible loss is limited to what you paid for them, minus anything you got back.

Stock options vest into the right to exercise, and vesting itself isn’t taxed. Some companies let you exercise before vesting, which gives you restricted stock and brings the 83(b) choice with it.

In an employee stock purchase plan, shares are yours as soon as you buy them. What matters instead is the holding period for a qualifying disposition: more than 2 years from the offering start and 1 year from the purchase.

Put every vest date on one calendar: equity tranches, the date your employer’s retirement contributions become fully vested, and any pension milestones. That calendar answers practical questions. What would leaving on a given date forfeit? Which tax years will each vest land in? How concentrated will your holdings be after the next few tranches?

Timing can be worth a lot. Leaving a week before a one-year cliff forfeits the whole first tranche, while waiting for a large vest before resigning can be worth months of pay. The same logic explains why unvested awards can turn a job you would otherwise leave into golden handcuffs.

For forecasting, count unvested amounts as expected future income, not as current net worth, and allow for the chance that you leave early or the share price falls. Vests in the same year stack: a year when an old grant and several refreshes overlap can push you into a higher tax bracket and call for extra withholding.

Vesting terms sit in documents most people read once, at hiring, and then forget. The costly errors tend to surface at the worst moment: when you give notice, when a company is sold, or when a tax bill arrives for shares you never sold. A short yearly review of your summary plan description and grant agreements, and another before any job change, catches most of them. These are the mistakes that come up most often:
