Stock options and RSUs: how Switzerland taxes them

Equity compensation is where expat tax returns most often go wrong: the wrong moment, the wrong value, or a gain taxed twice because you changed country during vesting. Here are the rules, and we check yours in English.

The rules in four points

RSUs: taxed when they vest

When the shares are delivered to you, their market value is salary. It appears on your salary certificate and is taxed like the rest of your pay.

Options: usually taxed at exercise

For unlisted options or options you cannot sell yet, the gain at exercise (share value minus exercise price) is salary. Freely tradable listed options are taxed when granted.

Blocked shares: a discount

Shares you must hold for some years are taxed on a lower value: 6% less per year of blocking period, up to 10 years.

After that: gains are tax-free

Once the shares are yours, selling them at a profit is a tax-free private capital gain in Switzerland. Dividends are taxed as income and the shares count as wealth.

Questions expats ask about equity compensation

How are RSUs taxed in Switzerland?
RSUs are taxed when they vest, that is when the shares are actually delivered to you. Their market value on that day is treated as salary, shown on your salary certificate and taxed with the rest of your income. Nothing is taxed at grant.
I moved to Switzerland while my RSUs or options were vesting. Who taxes what?
Switzerland only taxes the share of the gain that matches the time you worked in Switzerland during the vesting period. The part earned abroad is left to the other country. With employees moving between countries, this split is where most mistakes happen, so check it before you file.
I left Switzerland before my RSUs vested. Do I still pay Swiss tax?
Yes, on the Swiss part. Your former Swiss employer withholds Swiss tax at source on the share of the gain earned while you worked in Switzerland, even if you live abroad when the shares vest. Your new country may tax the same income, and the tax treaty decides who gives way.
I am taxed at source. Can my RSUs push me into a full tax return?
They can. Vested RSUs and option gains are part of your gross salary. In a good year they can take you above CHF 120,000, the amount from which a full tax return (subsequent ordinary taxation, TOU) becomes compulsory for residents taxed at source. Once that happens, you file a full return every year.
Is selling my shares taxed?
Not in Switzerland, as long as you hold them privately: capital gains on private shares are tax-free. Dividends are taxable income, and the shares are part of your wealth on 31 December, so they count for wealth tax.
Can you check my equity compensation in English?
Yes. We review your grant and vesting statements, your salary certificate and the split between countries, then prepare and file your Swiss return. One free 15-minute call is enough to tell you what needs checking: mytaxadvisor.ch/en/book-a-call/.
