RSU Taxation Switzerland 2026 — How RSUs Are Taxed for Expats

In Switzerland, RSUs (Restricted Stock Units) are taxed as employment income at the vesting date — the day the shares are delivered to you. The fair market value of the shares at vesting is added to your taxable income for that year (DBG Art. 17b; ESTV Kreisschreiben on direct federal tax). For B permit holders, withholding tax is deducted at vesting; if salary plus RSU income exceeds CHF 120000, you must file a Nachträgliche Ordentliche Veranlagung (NOV).

How RSUs are taxed in Switzerland

The vesting date is the taxable event

When your RSUs vest and shares are delivered:

1. The fair market value on the vesting date is calculated
2. This amount is treated as employment income (Erwerbseinkommen / revenu d'activité)
3. It is added to your gross income for the year
4. You are taxed at your marginal tax rate on this income

Key formula

Taxable RSU income = number of shares vested × market price on vesting date

Example: 100 shares vest on March 15, 2025. Share price at vesting: USD 200. Exchange rate: 0.88 CHF/USD.

• USD value: 100 × $200 = USD 20,000
• CHF value: USD 20,000 × 0.88 = CHF 17,600
• This CHF 17,600 is added to your taxable income for 2025

RSUs and withholding tax (B permit holders)

If you hold a B permit, your RSU income at vesting is subject to withholding tax (Quellensteuer). Your employer should:

1. Calculate the CHF value of vested shares at the vesting date
2. Add this to your gross income for that month
3. Deduct withholding tax at the applicable rate for that month's total income

Important: The month of RSU vesting will show significantly higher withholding tax — this is correct behavior.

If RSU income pushes you over CHF 120000

If your total annual income (salary + RSU income) exceeds CHF 120000, you are required to file a Nachträgliche Ordentliche Veranlagung (NOV). This is especially common for tech and finance professionals who receive annual RSU tranches.

Stock options — different rules

Employee stock options (Mitarbeiteroptionen) follow different rules from RSUs:

Type	Taxable event	Amount taxed
RSUs	Vesting (delivery of shares)	Market value at vesting
Unvested options (no vesting conditions met)	Grant date (if tradeable/liquid)	Calculated option value
Vested options (exercised)	Exercise date	Intrinsic value at exercise (market price − strike price)
Discount share purchases (ESPP)	Purchase date	Discount amount

Switzerland taxes options at grant if they are freely tradeable and have no vesting restrictions. Most US/UK employer options are not freely tradeable, so taxation typically occurs at exercise.

Special rules for expats — the proportional principle

If you were not resident in Switzerland for the entire vesting period, only a proportionate share of the RSU income is taxable in Switzerland.

Example: Proportional allocation

• RSUs granted: January 1, 2022 (while resident in Germany)
• RSUs vest: January 1, 2025 (after 2 years in Switzerland)
• Vesting period: 3 years total (1 year Germany, 2 years Switzerland)

Swiss-taxable portion = 2/3 × total RSU income

The remaining 1/3 may be taxable in Germany (depending on the Germany-Switzerland tax treaty).

This proportional calculation must be explicitly declared on your Swiss tax return — it is not automatic.

Double taxation risk with RSUs

Expats face double taxation risk if:

1. Your home country taxed RSUs at grant (common in some jurisdictions)
2. Switzerland taxes the same shares again at vesting

Switzerland has double taxation treaties (DTA) with 100+ countries. Relief mechanisms include:

• Exemption method — Swiss income exempt from home country tax
• Credit method — tax paid in one country credits against tax in another

If you have RSUs spanning two countries, consider:

• Applying for an expat tax ruling (Vorabentscheid) before vesting
• Documenting the split between Swiss and non-Swiss vesting periods precisely

How to declare RSU income on your Swiss tax return

On the tax return form

RSU income is declared in:

• Federal/cantonal forms: "Income from employment — other income" or a dedicated employee participation section
• You must attach a statement from your employer showing: number of shares, vesting date, price per share on vesting date, total CHF value

Employer certificate (Lohnausweis / certificat de salaire)

Your employer is required to report RSU income on the Lohnausweis. Check:

• Field 2 (irregular earnings / unregelmässige Bezüge) — RSU income should appear here
• If missing, request a corrected Lohnausweis from HR before filing

Practical checklist for RSU taxation

• Track each vesting date and market price (CHF value on that day)
• Check your Lohnausweis — RSU income must appear in Field 2
• Calculate Swiss residency days during vesting period for proportional allocation
• Determine if total income (salary + RSU) exceeds CHF 120000 — if yes, file NOV
• Check your home country DTA with Switzerland for relief provisions
• Consider requesting an expat tax ruling if RSU values are large (>CHF 50,000)
