Swiss withholding tax: tariffs, recalculation and NOV
A foreign employee who is tax-resident in Switzerland and does not yet hold a C settlement permit is generally taxed at source: the employer deducts the tax from salary and remits it to the competent canton. There is no single nationwide percentage. Canton, gross and rate-determining income, marital status, spouse income, children and other tariff data determine the deduction. Calculation errors use recalculation; additional deductions or mandatory cases may require NOV.
Short answer: how does Swiss withholding tax work?
A foreign employee who is tax-resident in Switzerland and does not yet hold a C settlement permit is generally taxed at source: the employer deducts the tax from salary and remits it to the competent canton. There is no single nationwide percentage. Canton, gross and rate-determining income, marital status, spouse income, children and other tariff data determine the deduction. Calculation errors use recalculation; additional deductions or mandatory cases may require NOV.
Quick facts
Who: mainly foreign employees resident for tax in Switzerland without a C permit; people resident abroad can also be taxed at source on certain Swiss income.
Collector: the employer withholds the amount and pays it to the competent cantonal tax administration.
Inputs: canton, income, marital status, spouse employment, children and church-tax indicator must be accurate.
Correction: an incorrect gross base, rate-determining income, tariff or disputed liability can justify recalculation.
Deadline: normally 31 March of the following year; the FTA describes it as a non-extendable forfeiture deadline.
NOV: it is mandatory from CHF 120,000 annual gross employment income for residents taxed at source; spouses' salaries are not added to reach this threshold.
1. Who is taxed at source?
The Federal Tax Administration source-tax page identifies two main groups: people tax-resident in Switzerland without a C settlement permit and people without Swiss tax residence who receive certain Swiss income. The employer deducts and remits the tax. Residence, cross-border status, international workdays and treaty allocation may require a separate analysis.
Use the Hungarian-Swiss tax-residence guide when the task is to decide which country is the residence state or how the treaty allocates income. This page owns the Swiss salary-withholding process and the choice between payroll correction, source-tax recalculation and NOV.
2. What does the tariff code represent?
The FTA Circular 45 and the 2026 federal calculation basis describe progressive tariffs. A generally represents single taxpayers, B a married household with one earner, C a married household with two earners or further income, and H a single-parent situation. The child count and church-tax indicator add further code elements. Payroll needs current, evidenced personal information.
Input | Why it matters | What to verify |
|---|---|---|
Canton | Tariffs differ between cantons | Competent canton and municipality |
Gross salary | Base for withholding | Pay period, bonus and benefits in kind |
Rate-determining income | Multiple jobs or replacement income can alter the rate | All relevant employment and replacement income |
Family situation | Selects the tariff family | Marriage, separation and spouse employment |
Children and church | Determine additional code elements | Current documented status |
The FTA published 2026 tariff files for all Switzerland, but these files are designed for payroll software. Use the readable table or calculator of the competent canton. The official Zurich tariff calculator is an example and explicitly says its output is not legally binding. It is not a substitute for another canton's tool.
3. Verify the withholding line on your payslip
Confirm the pay period, gross salary, bonus, thirteenth-salary component and other taxable benefits.
Read the Quellensteuer or QST amount, tariff code and income basis shown on the payslip.
Compare address, marital status, spouse income, children and church status with the employer's payroll record.
Use the competent canton's official table or calculator for the correct tax year.
Report a discrepancy to payroll in writing and request the tariff-code and rate-determining-income calculation.
Separate an employer payroll correction, formal source-tax recalculation and NOV; they solve different problems.
For AHV/IV/EO, unemployment insurance, accident insurance, BVG and the other salary lines, use the Swiss payroll-deductions guide. This canonical covers only withholding tax and its tax procedures.
4. Recalculation and NOV are different
The federal dossier limits recalculation to an incorrectly determined taxable gross salary, incorrectly calculated rate-determining income, incorrect tariff application or a dispute over whether source-tax liability exists. Personal deductions such as pillar 3a contributions or a pension-fund purchase cannot be claimed through this narrow recalculation procedure.
Situation | Correct route | Boundary |
|---|---|---|
Wrong gross base or tariff code | Source-tax recalculation | No additional personal deductions |
Pillar 3a, BVG purchase or other personal deductions | Voluntary NOV if eligible | Full income and asset declaration |
At least CHF 120,000 annual gross employment income | Mandatory NOV | Withholding is not necessarily the final tax |
Other income not taxed at source or assets | Check cantonal mandatory-NOV rules | Do not watch only the salary threshold |
Which country may tax an item | Residence and treaty analysis | The Swiss tariff code is not the treaty answer |
5. Mandatory and voluntary NOV
The FTA NOV overview states that NOV is mandatory for a Swiss-resident source-taxpayer with at least CHF 120,000 gross employment income. Spouses' employment income is not aggregated to reach the threshold. Additional income, assets or self-employment can create further mandatory cases under cantonal implementation.
Below the threshold, a resident taxpayer may request NOV for deductions not individually reflected in the tariff. A valid request is not a simple refund claim: it cannot be withdrawn, the ordinary-assessment process continues in later years until source-tax liability ends, and the final calculation can produce either a refund or additional tax. Use the Swiss tax-return and NOV guide for the complete filing process and the third-pillar guide for 3a and 3b rules.
6. Protect the 31 March deadline
A recalculation request and voluntary NOV request normally need to reach the competent authority by 31 March of the year following the income year. The deadline is non-extendable. For a person leaving Switzerland permanently, the NOV request deadline may already end when the departure is officially deregistered. Prepare the annual salary certificate, monthly payslips, source-tax certificate and evidence of family status, children, spouse income and deductions early.
Keep monthly payslips, the annual salary certificate and source-tax confirmations.
Record personal-status changes and their effective dates.
With multiple employers, request the rate-determining-income calculation.
Collect pillar 3a, BVG, childcare, maintenance, interest and medical evidence for NOV, not for a simple tariff recalculation.
Do not wait until late March if payroll and the tax office need time to respond.
7. Cantonal variation: Zurich as a bounded example
The current Zurich NOV page lists further mandatory triggers including more than CHF 3,000 of income not taxed at source and taxable worldwide assets above CHF 80,000 for an individual or CHF 160,000 for jointly taxed people. These are explicitly Zurich examples. They must not be copied to Bern, Basel, Geneva or another canton without checking that canton.
8. Intent boundary
This canonical owns Swiss wage withholding: scope, tariff, payslip verification, recalculation and the NOV decision point. Full tax-return filing, Hungarian-Swiss residence, other payroll deductions, pillar 3 and Hungary-Switzerland commuting remain separate tasks. Pension-capital refunds, German or Italian commuter percentages and personal treaty outcomes are not generalized here.
Common mistakes
Assuming one nationwide withholding percentage.
Using another canton's tariff or the wrong tax year.
Trying to claim pillar 3a through a simple tariff recalculation.
Watching only the CHF 120,000 threshold and ignoring other income or assets.
Promising a refund before comparing the full NOV result.
Treating 31 March as an extendable return deadline.
Applying German, Italian or French commuter rules to a Hungarian situation.

In Brief
Check the competent canton, tax year, tariff code and income basis. Calculation or tariff errors use recalculation; individual deductions and mandatory cases use NOV. The 31 March request deadline is non-extendable.
Key Takeaways
- There is no single nationwide Swiss withholding-tax percentage.
- The employer withholds the tax and remits it to the canton.
- Tariff errors and personal deductions require different procedures.
- Cantonal NOV duties can apply in addition to the CHF 120,000 threshold.
- The 31 March deadline is non-extendable and NOV can produce additional tax.
