Withholding tax refund service for expats and frontaliers taxed at source

We provide our withholding tax refund service in Switzerland for foreign employees and frontaliers who are taxed at source and want to reclaim the amount they have overpaid. This includes B and L permit holders, and G permit holders (cross-border workers from France).

Withholding tax in Switzerland — also known as tax at source — is a system where your employer — or your own company, if you hold a B permit and are a GmbH/Sàrl owner — deducts income tax directly from your salary before you receive it. The deduction is based on a standard tariff set by the cantonal tax authorities, which takes into account only basic factors such as your marital status and number of children.

The problem is that this standard calculation often does not reflect your actual situation. Deductions for commuting costs, childcare, pension contributions (pillar 3a), debt interest, and other personal expenses are not included automatically. The result is that you might pay more withholding tax than you actually owe.

At LedgerPeek, we help you identify every deduction you are entitled to, file the appropriate correction with your cantonal tax authority, and claim back every franc you are owed.

In Switzerland, most residents file an annual tax return and pay income tax based on their declared earnings and deductions — this is called ordinary taxation. Withholding tax, on the other hand, is deducted directly from your salary by your employer (or your own company) before you receive it, based on a fixed tariff. Foreign withholding tax applies primarily to foreign nationals with a B or L permit who do not hold a C (settlement) permit, as well as to non-resident workers such as frontaliers.

The key difference is that with ordinary taxation, you declare all your deductions yourself and the tax authorities calculate the final amount owed. With Swiss withholding tax, the tariff is applied automatically and often does not account for your full deduction entitlements — which is why a withholding tax refund is possible when the amount deducted exceeds what you actually owe.

If you are a foreign employee with a B or L permit, or a frontalier working in Switzerland, and your employer deducts Swiss withholding tax from your salary, there is a strong likelihood that you are overpaying. You may be eligible for a source tax refund in Switzerland if any of the following apply:

• You have work-related expenses such as commuting costs that are not reflected in your tariff
• You make contributions to pillar 3a or have other deductible pension payments
• You pay for childcare, have medical expenses, or carry debt interest
• Your family or financial situation has changed since the tariff was set
• You earn below CHF 120,000 and have never filed a rectification request or requested a subsequent ordinary assessment

Our experts assess your specific case during the initial consultation and provide a clear estimate of what you could get back.

We provide an end-to-end withholding tax refund service in Switzerland, which covers:

• Review of your personal, family, and financial situation to identify all eligible deductions
• Assessment of whether a rectification request or a subsequent ordinary assessment leads to a better financial outcome in your case
• Preparation and submission of all required documents to your cantonal tax authority
• Full communication with the authorities on your behalf — including follow-up correspondence, assessment review, and refund tracking

Our withholding tax refund service for frontaliers covers:

• Identification of all applicable deductions under the Franco-Swiss cross-border framework
• Assessment of whether quasi-resident status applies to your situation and whether it would improve your outcome
• Analysis of how your specific canton applies source taxation to frontaliers
• Preparation and submission of your rectification request to the relevant Swiss cantonal authority
• Full follow-up with the authorities — including correspondence, assessment review, and refund tracking

Quasi-resident status is available to non-resident employees and frontaliers who earn the majority of their worldwide income in Switzerland — typically 90% or more. If you qualify, you are entitled to claim the same deductions as ordinarily taxed Swiss residents, which may significantly reduce your tax burden. This status is particularly relevant for frontaliers working in cantons such as Geneva and Vaud.

Our specialists assess whether quasi-resident status applies to your situation and whether claiming it would lead to a better financial outcome than a standard rectification.

The deductions available depend on your canton, the type of correction filed, and your personal circumstances, but common withholding tax deductions in Switzerland include:

• Professional expenses: commuting costs, meals away from home, work tools and equipment
• Pension contributions: pillar 3a payments, voluntary buy-ins to pillar 2
• Insurance premiums: health and accident insurance costs beyond the mandatory minimum
• Childcare costs: external childcare expenses
• Debt interest: interest payments on personal loans or mortgages
• Training and education: costs of professional development directly related to your current role
• Charitable donations: contributions to registered Swiss charities

If you are eligible for a subsequent ordinary assessment or qualify for quasi-resident status, the range of deductions available to you is broader than what can be claimed through a rectification request alone.

We assess your specific situation and advise you on exactly which deductions can be claimed in your case, ensuring you receive the maximum withholding tax refund you are entitled to.

The refund amount depends on your salary level, canton, family situation, and the deductions you have not yet claimed. In many cases, foreign employees and frontaliers who have never filed a Swiss withholding tax reclaim find that they have been overpaying by a significant margin.

During the initial consultation, our tax specialists review your documents, assess your deduction opportunities, and provide a clear estimate of the expected outcome before any commitment — so you know the potential outcome before you proceed.

The documents required may differ depending on your situation. We encourage you to book a consultation with our tax expert, and they will send you the exact list of documents needed to review your case and file your withholding tax correction.

We provide our consultations in English and French, ensuring you can discuss your withholding tax situation in the language you are most comfortable with.

All documentation and correspondence with the authorities are handled in the relevant official language of your canton.

The price depends on your specific situation — including the type of correction needed, the complexity of your deductions, and the canton involved. After the initial consultation, we provide a clear scope and transparent fee estimate so you know exactly what to expect before proceeding.

We prioritise speed and reliability across our services. Once we have had the initial consultation and received all the necessary documents from you, we proceed straight away to analysing your situation, preparing your withholding tax correction, and submitting it to the relevant cantonal authority — keeping you informed at every stage of the process.

No. We handle all communication with the cantonal tax authority on your behalf. You are kept informed at every stage, but you do not need to contact the authorities directly.
