What is the B residence permit and how does withholding tax work The B residence permit is the standard authorisation for people who take up residence in Switzerland to work or live. Unlike the G cross-border permit, the B permit requires actual residence in the country, with registration at the local municipality within 14 days of arrival. It is normally issued for five years and is renewable provided the conditions (valid employment contract, sufficient financial means, health insurance) continue to be met. EU/EFTA citizens obtain it under the Free Movement Agreement (FMP), while third-country nationals fall under the quota regime of the Federal Act on Foreign Nationals and Integration (FNIA). ### Legal basis and procedure The Federal Act on Foreign Nationals and Integration (FNIA), together with the Ordinance on Admission, Residence and Gainful Employment (OASA), forms the framework for the B permit. The cantonal migration offices (in Ticino the Settore della migrazione) process the application as soon as the employer has notified the hiring. Important: those who move their residence to Switzerland after starting employment become fully tax liable in their canton of residence — regardless of where the employer is based. The transition to the C settlement permit typically occurs after five years (for privileged nationalities) to ten years of uninterrupted residence. ### Difference from the G cross-border permit and the C permit The key practical distinction concerns residence. A G permit holder lives in a neighbouring EU country (in our context usually Italy) and commutes — they remain resident in their home state and are taxed there, with partial withholding in Switzerland and credit under the new 2026 cross-border agreement. Those who choose the B permit instea...

Withholding tax 2026 — tariffs, categories and the CHF 120,000 threshold The 2026 withholding tax follows a uniform federal tariff scheme that the cantons adopt and multiply by their own tax multipliers. The main categories are: - Tariff A — single persons without children - Tariff B — married single-earners without children - Tariff C — married dual-earners (both employed) - Tariff D — abolished since 2021 (replaced by retrospective ordinary assessment for secondary employment) - Tariff E — simplified accounting procedure for very small salaries - Tariff H — single parents with dependent children in their own household - Tariffs L/M/N — special tariffs for cross-border workers from Germany, Italy and France Each group is further differentiated by number of children (0, 1, 2, 3, …) and confession (Y with church tax, N without). ### Ticino example: concrete tax rates For a single employee (tariff A0N) with a gross annual income of CHF 80,000 the effective Ticino withholding tax for 2026 is around 9–11 %, depending on the municipality of residence. For a dual-earner couple with two children (tariff C2N) and a combined gross income of CHF 130,000 the effective rate drops to 6–7 %. To calculate your individual burden, use the official withholding tax calculator combined with the Frontaliere salary tool — both faithfully reproduce the cantonal tariffs and show both the gross-net difference and the effective rate. ### Recognised deductions in withholding tax The flat-rate tariffs already include standard deductions for professional expenses, insurance premiums and social deductions for children. The following may also be considered upon request: - Pillar 3a contributions up to the legal maximum (2026: CHF 7,258 for employees with BVG/LPP affiliation) - Pension fund bu...

Procedure, special cases and comparison with cross-border status ### Step by step: NOV application via the cantonal portal In Ticino the request for retrospective ordinary assessment is made via the eTax portal of the Divisione delle contribuzioni (etax.ti.ch). The main steps: 1. Registration with AHV/AVS number, withholding tax identification number (shown on the salary statement) and a personal activation code (requested by post). 2. Filling in the tax return — declare income (salary, secondary employment, pensions, capital income), deductions (Pillar 3a, professional expenses, health insurance premiums, debt interest) and any foreign assets. 3. Attaching supporting documents — salary statement, Pillar 3a certificate, childcare invoices, medical certificates for illness costs. 4. Submission by 31 March of the following year; if necessary request an extension (usually granted until 30 September). 5. Awaiting the assessment decision — the cantonal tax administration reviews the return and issues a definitive decision against which an objection can be filed within 30 days. For first-time applicants, the complete tax return guide for cross-border workers and B holders offers a step-by-step overview including a checklist of required documents. ### Special cases: spouses, children and joint assessment Married B holders are in principle assessed jointly (family taxation). Both spouses' incomes are added together, which due to tax progression often results in a higher burden — the famous marriage bonus/penalty. Family splitting and the married couple deduction partially mitigate the effect. If both spouses are gainfully employed, tariff C automatically applies (instead of B). Children are accounted for via the child deduction (CHF 6,700 per minor child, federal 2026) an...

- B residence permit vs G cross-border worker: which is better for taxes?
- There is no universal answer — the decision depends on cost of living, family situation and personal preferences. B holders pay all taxes in Switzerland and benefit from Swiss social benefits but bear high Swiss rents and health insurance premiums.

The [complete overview of permit types](nav:permits) helps with the choice.
- What happens to spouses and children under withholding tax?
- Married B holders are jointly assessed (family taxation), with both spouses' incomes added together. If both spouses work in Switzerland, tariff C applies (instead of B). If the spouse lives abroad, they remain liable in their state of residence — the B holder is then taxed as a single earner. Children are accounted for via the child deduction (CHF 6,700 per minor child, federal 2026). Marriage, birth or separation must be reported to the employer within 30 days.
