How can I correctly understand Swiss payroll deductions?
The Swiss system of payroll deductions is complex: AVS, ALV, withholding tax, KVG – this article explains exactly what is deducted from your salary, why it is deducted, and what you should pay attention to.
What is deducted from gross pay? Types and order of payroll deductions
Swiss payroll deductions can be divided into two main groups: mandatory statutory deductions and other contractual or voluntary deductions.
Mandatory statutory deductions
The employer is required to deduct these from every employee, regardless of the type of employment contract or the extent of working hours:
Type of deduction | Abbreviation (DE/FR) | Employee share (approx.) |
|---|---|---|
Old-age, survivors’ and disability insurance | AHV/AVS + IV/DI | 5.3% (AHV 4.35% + IV 0.7% + EO 0.25%) |
Unemployment insurance | ALV/AC | 1.1% (up to a salary cap of CHF 110,800) |
Accident insurance (occupational) | UVG/LAA – BU | paid by the employer |
Accident insurance (non-occupational) | UVG/LAA – NBU | paid by the employee (approx. 1–3%, depending on the premium) |
Second pillar – mandatory portion | BVG/LPP | depending on age and salary, typically 3.5–9% |
The employer deducts these employee contributions and transfers them, together with the employer’s own contributions, to the relevant institutions.
Withholding tax (Quellensteuer)
Employees who do not have Swiss citizenship and have not been granted a settlement permit (C permit / Niederlassungsausweis C), are generally subject to withholding tax. This means that the employer also deducts income tax directly from the gross salary and the employee does not file a standard tax return — unless certain conditions (e.g. annual gross salary exceeding CHF 120,000, or ownership of Swiss real estate) make this mandatory.
Hungarian citizens — as EU citizens under the Agreement on the Free Movement of Persons (FZA, Freizügigkeitsabkommen, 1999) — with a B or L permit are typically subject to withholding tax, until they receive a C permit.
Other deductions
The payslip may also include:
Third pillar (Säule 3a) contributions – if requested by the employee and processed by the employer
Meal allowance withholding, if the employer provides meals
Advance repayment withholding in the case of earlier payments
Trade union dues – if the employee has agreed to this
How does the Swiss progressive tax system work?
Federal, cantonal and municipal tax
In Switzerland, income tax is levied at three levels:
Federal tax (direkte Bundessteuer / impôt fédéral direct): a uniform progressive scale, with a maximum rate of 11.5% in 2026 for the highest income bracket.
Cantonal tax (Kantonssteuer / impôt cantonal): varies from canton to canton, with its own progressive scale. This is the main source of variation – the tax burden in Zug canton can be only a fraction of that in Genève or Bern canton.
Municipal tax (Gemeindesteuer / impôt communal): a fixed multiplier of the cantonal tax, also varying locally.
Example of the difference: For the same annual gross income of CHF 80 000, the effective tax burden in Zug may be around 10–13%, while in Genève it can be around 25–30%. This difference is a decisive factor when choosing a place of residence.
Withholding tax rates and tables
Withholding tax (Quellensteuer) is determined by the cantons based on their own tables, taking into account:
the monthly gross salary amount,
marital status (single / married / number of children),
the obligation to pay church tax.
Withholding tax rates are updated every year. The employer is required to apply the correct code based on the data provided by the employee.
Social security contributions (AVS/AHV, DI/IV, EO, ALV): obligations and calculation
The first pillar: AVS/AHV + IV/DI + EO
The first pillar (erster Pfeiler / premier pilier) is the foundation of Switzerland’s social safety net. In 2026, the total contribution rate as an employee and as an employer is 5.3% on the employee side (the employer pays the same amount on top):
AHV/AVS (old-age and survivors’ insurance / Alters- und Hinterlassenenversicherung): 4,35%
IV/DI (disability insurance / Invalidenversicherung): 0,7%
EO (earnings compensation / Erwerbsersatzordnung): 0,25%
These are not subject to a salary cap – they are payable on the full gross salary.
Unemployment insurance (ALV/AC)
The ALV (Arbeitslosenversicherung / assurance-chômage) contribution in 2026 is:
1,1% from the employee side, up to the annual salary cap of CHF 110 800,
above that a 0,5% solidarity contribution (Solidaritätsbeitrag) applies, but this portion does not entitle the employee to ALV benefits.
Second pillar (BVG/LPP)
The mandatory occupational pension scheme (berufliche Vorsorge / prévoyance professionnelle) operates under BVG/LPP. The contribution rate depends on age and the amount of the “coordinated salary” (koordinierter Lohn):
Age | Employee contribution (min.) |
|---|---|
25–34 years | 3,5% |
35–44 years | 5,0% |
45–54 years | 7,5% |
55–65 years | 9,0% |
The employer pays at least the same amount. Many employers also provide the so-called “überobligatorisch” (above-mandatory) portion, which exceeds the legal minimum.
Health insurance premiums and other optional deductions
Health insurance (KVG/LAMal) is not a payroll deduction
This is one of the most common misunderstandings: in Switzerland, the premium for basic health insurance (Grundversicherung / assurance de base) is not deducted from salary by the employer, but is paid directly by the employee to the chosen insurer (Krankenkasse). This can range from CHF 300 to CHF 600 per month, depending on the canton, insurer and the chosen deductible (önrész / Franchise).
Some employers voluntarily contribute to the KVG premium, but this is neither mandatory nor standardised.
Accident and supplementary insurance
Occupational accident insurance (BU / Berufsunfall): is paid in full by the employer.
Non-occupational accident insurance (NBU / Nichtberufsunfall): is settled through the employee’s payroll deduction; the rate varies by insurer and sector.
Daily sickness allowance (KTG / indemnité journalière maladie): is not mandatory, but many employers provide it through collective agreements; the premium is shared by employer and employee.
Common mistakes: what should not be overlooked
1. The withholding tax code is incorrect
If the employer applies the wrong withholding tax code (for example, treating a married employee as single), the deduction will be incorrect. The employee is obliged to report any changes (marriage, birth of a child, second income) without delay to the employer and the competent cantonal tax office (Quellensteueramt).
2. Misunderstanding the BVG coordinated salary
The BVG contribution does not apply to the full gross salary, but to the “coordinated salary,” from which the so-called coordination deduction (Koordinationsabzug) is subtracted. In 2026, this amount is CHF 26 460 per year. If someone works part-time, the coordinated salary decreases proportionally, which means lower BVG contributions – and a smaller pension capital.
3. Ignoring the ALV salary cap
If the gross salary exceeds CHF 110 800 per year, no ALV benefits are paid on the portion above that amount, but a solidarity contribution is still due. Many people are unaware of this and misunderstand how net pay develops in higher salary ranges.
4. The risk of double taxation
For Hungarian citizens, the double taxation treaty between Hungary and Switzerland (1981, as amended) determines which country may tax the income. As a rule, Switzerland taxes employment income earned in Switzerland, but there may also be a filing obligation toward the Hungarian tax authority (NAV). This should be clarified individually, especially if someone also has income in Hungary at the same time.
5. Failing to check the payslip
Many employees do not regularly review the items on their Lohnabrechnung. Administrative errors (for example, incorrect salary classification or missed BVG contributions) can remain unnoticed for years.
Self-employed persons and entrepreneurs: different rules and obligations
AHV/AVS as a self-employed person
Self-employed persons (Selbstständigerwerbende) do not pay contributions through an employer; instead, they register directly with the competent AHV compensation fund (Ausgleichskasse / caisse de compensation). The contribution rate depends on income and ranges from 5,196–10,0% (according to 2026 data), on a degressive scale – the lower the income, the higher the percentage burden.
BVG and self-employment
Self-employed persons are not mandatorily members of the BVG system. They may join a sectoral or freely chosen BVG fund, or provide for themselves under the third pillar (Säule 3a). In 2026, contributions of up to CHF 35 280 per year are tax-deductible under this option (for employees, the limit is CHF 7 258).
ALV as a self-employed person
Self-employed persons are not entitled to ALV benefits and, as a rule, do not pay ALV contributions either. This poses a serious risk in the event of unemployment – if self-employed status is lost, there is no automatic benefit entitlement.
Tax return
Self-employed persons are always required to file an annual tax return and settle tax prepayments (Steuervorauszahlungen) quarterly. The withholding tax system does not apply to them.
Review and complaint options: how can the correctness of payroll deductions be checked?
The items on the payslip
Every employee has the right to receive a detailed Lohnabrechnung. The steps for checking it are:
Gross salary: does it match the employment contract?
AHV/IV/EO deduction: 5.3% of gross salary?
ALV deduction: 1.1% of gross salary (up to CHF 110,800)?
BVG deduction: does it correspond to the age group and coordinated salary?
Withholding tax code: are marital status and number of children correct?
NBU premium: does it match the premium of the insurance taken out by the employer?
Complaint and correction
In the event of a withholding tax error: a request to amend the code or for a refund can be submitted to the cantonal Quellensteueramt. The deadline is typically 31 March following the tax year, but this varies by canton.
In the event of a BVG error: notify the employer’s BVG institution (Pensionskasse) in writing; the institution is obliged to send an annual statement (Vorsorgeausweis).
In the event of an AHV error: complain to the competent Ausgleichskasse; an individual AHV account statement (Kontoauszug) can be requested.
In the event of an employment law dispute: the cantonal labour court (Arbeitsgericht / tribunal des prud'hommes) is the competent forum.

In Brief
Several mandatory deductions are taken from gross salary in Switzerland: AHV/IV/EO, ALV, the second pillar, and in many cases withholding tax. The amount of net salary is significantly affected by the canton, the withholding tax code, the coordinated salary, and the fact that health insurance premiums do not appear as a payroll deduction.
Key Takeaways
- Check whether the AHV/IV/EO deduction shown on the payslip corresponds to 5.3% of gross salary.
- Verify that the ALV deduction is 1.1% up to CHF 110,800, and that only the solidarity contribution applies to the amount above that threshold.
- Check the BVG deduction based on age and coordinated salary, because it is not calculated on the full gross salary.
- Make sure the withholding tax code matches your marital status and number of children, especially after marriage or the birth of a child.
- Take into account that basic health insurance premiums are not a payroll deduction, but a separate monthly expense paid directly.
- If you notice a discrepancy on the payslip, report it to the relevant authority: for withholding tax, the Quellensteueramt; for BVG, the Pensionskasse; for AHV, the Ausgleichskasse.
Frequently Asked Questions
Which deductions are mandatory from a Swiss gross salary?
Mandatory deductions include AHV/IV/EO, ALV, non-occupational accident insurance (NBU), and the employee share of the second pillar, meaning BVG/LPP. These are deducted by the employer and forwarded to the relevant institutions. The exact amount depends on salary, age, and insurance conditions.
Does the employer deduct Swiss health insurance premiums from salary?
No, the basic health insurance premium (KVG/LAMal) is not a payroll deduction. The employee pays it directly to the insurer, and it can amount to roughly CHF 300–600 per month. Some employers may contribute voluntarily, but this is not mandatory.
Who pays withholding tax in Switzerland?
Typically employees who are not Swiss citizens and do not hold a C permit. Hungarian citizens with a B or L permit are usually subject to withholding tax until they receive a C permit. In such cases, the employer deducts income tax directly from the salary.
Why can net pay differ between two Swiss cantons with the same gross salary?
Because income tax applies at federal, cantonal, and municipal level in Switzerland. Cantons apply their own tax rates, so the same gross salary can result in a much lower tax burden in Zug than in Genève. Place of residence therefore has a material impact on net income.
What does coordinated salary mean in BVG?
The BVG contribution is not based on the full gross salary, but on the coordinated salary. The coordination deduction is subtracted from this amount, and in 2026 it is CHF 26,460 per year. For part-time work, this is reduced proportionally, which means pension contributions can also be lower.
How can you check whether payroll deductions are correct?
On the payslip, it is worth checking the gross salary, the AHV/IV/EO deduction, ALV, BVG, the withholding tax code, and the NBU premium. If there is a discrepancy, the competent authority is the cantonal Quellensteueramt for withholding tax, the Pensionskasse for BVG errors, and the Ausgleichskasse for AHV errors.
What happens if the withholding tax code on the payslip is wrong?
If the employer uses the wrong code, the deduction may be incorrect, for example treating a married employee as single. Changes such as marriage or the birth of a child should be reported immediately to the employer and the competent cantonal tax office. In most cases, a correction procedure can also be requested.
