How are employee stock options and equity taxed in Switzerland?

Employee stock options and restricted stock units (RSUs) in Switzerland are taxed as employment income at the time of vesting or exercise, not at grant. The taxable amount is the market value of the shares received minus any amount paid by the employee. This value is added to your salary and subject to income tax and AHV contributions in the year it vests.

For options with a holding period or vesting schedule, the canton may apply a reduced rate formula that spreads the gain over the vesting period. The FTA issued detailed guidance in Circular 37a (2013) covering different equity instrument types and their specific tax treatment — the rules differ for freely tradeable vs restricted shares and for options vs RSUs.

If you leave Switzerland before vesting completes, cantonal tax authorities will typically tax the portion of the vesting period during which you were resident (pro-rata). The country where you vest the rest may also claim a portion. This international dimension is complex for globally mobile employees and typically requires specialist advice.
