Switzerland Withholding Tax 2026: All Border Cantons Compared

Contesto

Withholding tax (Quellensteuer / impôt à la source) is the Swiss payroll deduction for workers without a C settlement permit — it is taken directly by the employer from gross monthly pay. In 2026 all cross-border workers with a G permit and all B-permit holders are subject to it. Cantonal rates range from 1% to 25%, with a NOV threshold of CHF 120,000 gross annual income for mandatory ordinary assessment. Find out here where the tax is lowest and how much you can recover via Pillar 3a.

What is withholding tax in Switzerland? Withholding tax (German Quellensteuer, French impôt à la source, Italian imposta alla fonte) is governed by the Federal Direct Tax Act (DBG/LIFD, articles 83–101) and the Federal Tax Harmonisation Act (StHG/LAID, articles 32–38). It is a collection method for income tax in which not the worker but the employer acts as debtor toward the canton. ### Who pays withholding tax? In 2026 the following persons are subject to Swiss withholding tax: - Cross-border workers with a G permit commuting daily or weekly from Italy, France, Germany or Austria - B-permit holders (residence) without a C permit (settlement) - L-permit holders (short-term residence) - Ci-permit holders whose spouse works for an international organisation - S-permit holders (protection status) Swiss citizens and C-permit holders are not subject to it; they are taxed under the ordinary assessment procedure. ### How the employer withholds the tax Monthly, on the gross salary after social deductions (AHV/IV/EO 5.3%, ALV 1.1%, NBU ~0.8%, BVG age-dependent 7–18%), the employer: 1. Calculates gross monthly pay (including pro-rata 13th salary, bonuses, fringe benefits) 2. Applies the tariff tables of the canton of residence or work 3. Withholds and remits the tax monthly to the cantonal tax administration Cantonal tariff tables are updated annually (effective 1 January 2026) and are organised by marital status: - Tariff A: single, no children - Tariff B: married, single earner - Tariff C: married, dual earners (usually the most favourable) - Tariff H: single parent with dependent children - Tariff F: Italian cross-border workers (Ticino only, pre-2024 agreement) For cross-border workers from 2024 onward (so-called "new cross-border workers" under article 6 of the It...

Cantonal tariffs 2026: comparison of the main border cantons The table below shows indicative 2026 withholding tax rates for the five cantons most relevant to Italian cross-border workers, calculated on an average gross annual salary of CHF 80,000. The cantonal rate already includes federal, cantonal and municipal tax (weighted average). | Canton | Tariff A (single) | Tariff B (married, 1 child) | NOV threshold | Key feature | |---|---|---|---|---| | Ticino (TI) | 11–13% | 4–6% | CHF 120,000 | 20% reduction for new G-permit cross-border workers from 2024 | | Graubünden (GR) | 9–11% | 3–5% | CHF 120,000 | Lowest cantonal rate, high municipal variability | | Valais (VS) | 12–14% | 5–7% | CHF 120,000 | High municipal tax in tourist municipalities | | Bern (BE) | 13–15% | 6–8% | CHF 120,000 | Cantonal rate below federal median | | Zurich (ZH) | 11–13% | 4–6% | CHF 120,000 | Lowest cantonal tax, high cost of living | ### Ticino (TI) — the cross-border canton par excellence With over 80,000 Italian cross-border workers, Ticino is by far the most important canton of work. From 2024 the new Cross-Border Worker Agreement with Italy applies: G-permit holders who started work after 17 July 2023 pay the Ticino withholding tax reduced to 80% and are simultaneously subject to IRPEF in Italy (with tax credit). Full details and 2026 tariff tables are on our Quellensteuer Ticino page. ### Graubünden (GR) — the alternative for cross-border workers from Sondrio and Valchiavenna The canton of Graubünden offers lower cantonal rates than Ticino but has strong municipal variability. In Chur the multiplier is at 100%, in some mountain municipalities over 130%. Cross-border workers from the province of Sondrio (Valchiavenna, Valtellina commuters) benefit from shorter commuting times to Po...

NOV application and deductible items The subsequent ordinary assessment (NOV — nachträgliche ordentliche Veranlagung) is the procedure by which a person subject to withholding tax aligns their tax status with ordinary assessment and can claim their actual deductions (article 89a DBG/LIFD). ### When is NOV mandatory? NOV is mandatory when: - Gross annual salary exceeds CHF 120,000 (single or married with one earner) - The person has other income above CHF 3,000 yearly (rentals, securities income, self-employment) - The person has wealth above the cantonal threshold (usually CHF 80,000 single, CHF 150,000 married) In all other cases NOV is optional and must be requested by 31 March of the following year (for tax year 2026 by 31 March 2027) at the cantonal tax administration. Missed deadlines cannot be recovered. ### Which deductions does NOV allow? Cross-border workers and B-permit holders can claim the following deductions in NOV, not included in the withholding tax flat rate: - Pillar 3a (restricted private pension): up to CHF 7,258 per year 2026 for those with an occupational pension fund, up to CHF 36,288 without. Fully deductible from taxable income. Learn more with our Pillar 3a Simulator. - Professional expenses: actual commuting costs (car up to CHF 0.70/km or actual public transport), meals at work (CHF 15/day), work clothing - Training and retraining: up to CHF 12,900 per year 2026 — language courses, certifications, master's degrees with professional connection - Health insurance premiums (KVG/LAMal basic) — only the share above the flat-rate deduction - Mortgage interest on residential property (also located in Italy, with Swiss tax credit) - Maintenance payments and alimony to separated spouses and minor children - Donations to tax-exempt organisation...

[{"q":"Where is withholding tax in Switzerland the lowest?","a":"For single earners (Tariff A) at CHF 80,000 gross, Zurich (11–13%) is on a par with Graubünden (9–11%) and Ticino (11–13%) at the lower end, followed by Valais (12–14%) and Bern (13–15%). For married cross-border workers with children (Tariff B), Graubünden tends to be the most favourable. However, cost of living and commuting distance heavily affect net savings — pure rate optimisation is too narrow."},{"q":"From what income must I apply for NOV?","a":"Subsequent ordinary assessment (NOV) is mandatory above CHF 120,000 gross annual salary (single or married single-earner). It is also mandatory with side income above CHF 3,000 yearly (rentals, securities) or wealth above the cantonal threshold (usually CHF 80,000 single, CHF 150,000 married). Below these thresholds NOV is optional and must be requested by 31 March of the following year — it almost always pays off if you contribute to Pillar 3a or have high professional expenses."},{"q":"What can I deduct from withholding tax?","a":"With the NOV application you can claim: Pillar 3a up to CHF 7,258/year 2026 (with occupational pension), actual professional expenses (commuting, meals, work clothing), training up to CHF 12,900/year, health insurance premiums above the flat rate, mortgage interest, alimony, donations up to 20% of net income, and extraordinary medical expenses above 5% of net income. Keep receipts for 10 years."},{"q":"How is withholding tax calculated for married couples?","a":"Married couples fall under Tariff B (single earner) or Tariff C (dual earners). C is usually more favourable because progression is applied to each salary separately rather than to the joint income. If your spouse has their own income, request Tariff C from your employer...
