First-time tax filing in Switzerland: the NRI guide

Welcome to Switzerland. If you have recently moved to the land of the Alps, you have likely noticed that life here is organized, beautiful, and full of paperwork. Tax season is no exception. This guide cuts through the complexity so you can file with confidence, avoid costly mistakes, and keep more of what you earn in both Switzerland and India.

Do I even need to file?

Most NRIs on a B-permit have income tax deducted directly from their salary via Withholding tax. It may feel like you are done, but you are required to file a full tax return if any of the following apply:

Income threshold. Gross annual salary exceeds CHF 120,000.
Foreign income. More than CHF 3,000 per year from outside your salary (Indian rental income or dividends, for example).
Significant wealth. Assets (savings, property in India) exceeding cantonal thresholds, often ~CHF 80,000 for singles.

The India factor: declaring your worldwide income

As a Swiss tax resident, you must declare your worldwide income and assets, not just what you earn in Switzerland. This surprises many first-time filers.

What to declare

Your flat or house in Bengaluru (or any Indian city).
NRE / NRO fixed deposits.
Indian stocks, mutual funds, or other investments.
Rental income from India.

Will I be double-taxed?

No. The India-Switzerland Double Taxation Avoidance Agreement (DTAA) makes sure you do not pay tax on the same income twice. Your Indian home may marginally increase your Swiss tax rate through the progression method, but you will not be billed for it twice. If you also file Indian tax, we cross-check the DTAA credit before either return goes in, and the cross-border bundle knocks 10% off both.

Maximize your savings: the NRI deduction checklist

Don’t leave money on the table. These deductions can significantly reduce your taxable income:

Pillar 3a contributions. Up to CHF 7,258 (2025) contributed to a Pillar 3a retirement account is 100% deductible. One of the most powerful tax levers available in Switzerland.
Commuting and meals. Your GA travel pass and the cost of eating lunch away from home are deductible up to cantonal limits.
International debt interest. Interest paid on loans, including home loans in India, can often be deducted from your Swiss taxable income.
Education and professional development. German or French language courses, professional certifications, and job-related training costs are typically deductible.

Deadlines and extensions

Standard deadline. 31 Mar for most cantons. Mark your calendar early.
Extensions available. Most cantons (Zürich, Genève, Vaud) grant a free extension requested online, often pushing your deadline to September or even November. Just apply in time.

Frequently asked questions

Q: I’m on a B-permit and earn CHF 90k. Do I need to file? A: Not automatically. Withholding tax covers you. But if you have Indian rental income over CHF 3,000 or significant Indian assets, you must file. And even if not required, voluntary filing (NOV) may benefit you if you have deductible expenses.

Q: Do I need to declare my NRE account balance? A: Yes. As a Swiss tax resident, you must declare worldwide assets including NRE / NRO balances. The DTAA makes sure you are not taxed twice, but non-disclosure carries risk.

Q: Can I deduct my home loan EMI in India? A: The interest portion of your home loan can typically be deducted in Switzerland. The principal repayment is not deductible, but the property value is declared as an asset.

Q: What happens if I miss the 31 March deadline? A: Request an extension immediately via your cantonal tax portal. Most cantons grant this for free. Ignoring the deadline can result in a tax assessment by the authorities, often unfavorable.

Q: What is Pillar 3a and why should I contribute? A: Pillar 3a is Switzerland’s private pension savings scheme. Contributions up to the annual limit (CHF 7,258 in 2025) are fully tax-deductible from your cantonal and federal income, reducing your tax bill while building retirement savings.
