Swiss L Permit: Short-Term Residence for Workers and Founders

The Swiss L permit (Kurzaufenthaltsbewilligung) is the short-term residence authorisation for foreign nationals working in Switzerland on fixed-term contracts of up to 12 months. It is governed by the Federal Act on Foreign Nationals and Integration (Ausländer- und Integrationsgesetz, AIG, commonly referred to by its English abbreviation FNIA) and its implementing ordinance VZAE. For EU/EFTA nationals it is issued under the Agreement on the Free Movement of Persons (FZA). For nationals of all other countries it is quota-based and subject to the Swiss labour market priority check. This guide explains eligibility, duration, the application process, and the L permit's tax implications under Swiss Quellensteuer rules.

What Is the Swiss L Permit?

The L permit is a category of Swiss residence permit specifically designed for short-term stays tied to a fixed-term employment contract. Unlike the B permit (annual residence) or the C permit (permanent settlement), the L permit is not designed for long-term integration. It authorises residency and employment simultaneously, but only for the duration of the employment contract and in no case for longer than 12 months per grant.

The permit is issued as a biometric card (Ausländerausweis) by the cantonal migration authority (Migrationsamt) of the canton where the employer is located. The application is submitted by the employer in most cases. The L permit's legal basis in statute is AIG Arts. 32 (permit categories) and 19 (conditions for employment of non-EU nationals); the procedural rules are set out in VZAE.

The L permit is distinct from a Swiss business visa: a business visa (Schengen Type C) permits short visits of up to 90 days but does not authorise employment. An L permit authorises both residency and employment but requires a fixed-term contract and, for non-EU nationals, quota availability. These are separate instruments and cannot be substituted for each other.

L Permit for EU/EFTA Nationals

Citizens of European Union and EFTA member states benefit from the Agreement on the Free Movement of Persons (FZA) between Switzerland and the EU. Under the FZA, EU/EFTA nationals are entitled to an L permit as of right when they hold an employment contract lasting between 3 months and 12 months with a Swiss employer. There are no annual quotas, no labour market priority check, and no obligation for the employer to demonstrate that no Swiss candidate was available.

The 8-Day Advance Notification

For employment contracts lasting between 8 days and 3 months, EU/EFTA nationals do not need a permit at all. The employer must instead file an 8-day advance notification through EasyGov.swiss before the assignment begins. This notification system replaced the old short-term notification for this category. For contracts between 3 months and 12 months, the employer applies for an L permit at the cantonal Migrationsamt before commencement of employment. The permit is typically issued within a few days for EU/EFTA nationals because the FZA entitlement is procedurally straightforward.

When the FZA Triggers a B Permit Instead

If the employment contract exceeds 12 months or is of indefinite duration, an EU/EFTA national does not receive an L permit: they receive a B permit with a 5-year validity (or equal to contract length if the contract is fixed-term between 1 and 5 years). The distinction matters for planning purposes: a founder or executive intending to be based in Switzerland for more than one year should apply for a B permit from the outset rather than accepting an L permit and transitioning later.

L Permit for Non-EU/EFTA Nationals

For nationals of countries outside the EU and EFTA, the L permit is quota-based and subject to the Swiss labour market admission conditions set out in FNIA Arts. 18-22. Switzerland applies a two-tier labour market priority: Swiss nationals first, then EU/EFTA nationals, then third-country nationals. An employer applying for an L permit for a non-EU/EFTA national must demonstrate to the cantonal labour authority that no suitable Swiss or EU/EFTA candidate was available for the position (the priority check, or Inländervorrang).

2026 Quota for Non-EU/EFTA L Permits

For 2026, Switzerland has maintained its annual quota of 4,000 L short-stay permits for non-EU/EFTA nationals, unchanged from 2025 and fixed by the amendment to the Ordinance on Admission, Residence and Employment (VZAE) that entered into force on 1 January 2026. A further 4,500 B residence permits are available for non-EU/EFTA nationals in 2026, bringing the total third-country quota to 8,500 work authorisations for the year. The quota is divided between cantonal allocations and a federal reserve and is drawn down over the course of the year. Because availability changes as the annual allocation is consumed, employers should verify current capacity with the State Secretariat for Migration (sem.admin.ch) before committing to a hire.

Salary and Qualification Requirements

Non-EU/EFTA nationals applying for an L permit must meet Swiss salary and qualification conditions. The position must be a qualified occupation, and the salary offered must meet the customary rates for the sector and region in Switzerland (Orts- und Branchenüblichkeit). Below-market salaries are a common ground for rejection. Unskilled or low-wage roles are not accessible through the L permit quota for non-EU nationals.

Who Needs an L Permit?

The L permit is required by any foreign national who intends to both reside and work in Switzerland under a fixed-term employment contract of up to 12 months. The following categories typically use the L permit:

• ●Fixed-term employees: Foreign nationals hired on contracts with a defined end date of up to 12 months, for project work, maternity cover, or seasonal assignments.
• ●Posted workers: Employees of a foreign company posted to Switzerland for up to 12 months under an intra-company assignment agreement.
• ●Seasonal workers: Workers in sectors with defined short-term demand, including construction, hospitality, and agriculture, where multi-year seasonal employment creates a recurring permit cycle.
• ●Founders in the pre-B permit phase: Occasionally, a founder whose B permit application is pending may work on an L permit as a transitional measure if the employer has offered a fixed-term contract pending approval of a longer-term permit. This is uncommon and requires specific structuring advice.

Cross-border commuters who maintain their principal residence abroad and travel to Switzerland for work use the G permit instead of the L permit. The G permit and L permit are mutually exclusive: the L permit presupposes residence in Switzerland.

Duration and Renewal Rules

The L permit is valid from the date of issue until the end of the employment contract, subject to the 12-month ceiling. The permit document records the exact expiry date. Several rules govern extension and renewal:

The L permit expires automatically when the contract ends, even if the 12-month ceiling has not been reached. If the employer terminates the contract early, the permit holder has no right to remain in Switzerland after the contract end date on the basis of the L permit alone. The holder must either depart Switzerland or, if a new employment contract is available, apply for a new L permit or a B permit.

For non-EU/EFTA nationals, the L permit is also tied to the specific employer named in the permit. Changing employer requires a new permit application and, for non-EU nationals, a new quota allocation and priority check. This is a significant limitation compared to the B permit, which after the initial period allows greater employer mobility.

Tax Treatment: Quellensteuer (Withholding Tax)

L permit holders who do not hold a C permit are subject to Swiss withholding tax on employment income (Quellensteuer). This is the standard tax collection method for foreign nationals without permanent residence in Switzerland. Rather than filing an annual tax return and settling tax afterwards, the employer deducts the applicable tax amount directly from gross salary each month and remits it to the cantonal tax authority (Steuerverwaltung).

How Quellensteuer Rates Are Set

Quellensteuer rates are set by each canton independently and published in annual tariff tables. The tariff applied depends on:

• ●Canton of employment (where the employer's payroll is registered)
• ●Gross monthly salary level
• ●Marital status (single / married)
• ●Number of dependent children
• ●Church membership (in cantons where church tax applies through Quellensteuer)

Cantonal Quellensteuer tariff tables are reissued each year, so the net rate at a given income level can change from one year to the next. Zug's tariff tables are published annually by the Zug Steuerverwaltung (zg.ch/steuern).

Ordinary Assessment for High Earners

L permit holders whose gross Swiss-source employment income exceeds CHF 120,000 per year are subject to a mandatory subsequent ordinary tax assessment (nachträgliche ordentliche Veranlagung) under DBG Art. 89; the CHF 120,000 threshold is set by the federal Withholding Tax Ordinance (QStV) and applies as of 2026. Under the ordinary assessment, the employer still deducts Quellensteuer as a prepayment, but the employee files a tax return and settles any difference between the Quellensteuer withheld and the ordinary tax due. This provision is relevant for senior executives and highly compensated short-term assignees.

L Permit vs B Permit: Key Differences

The L and B permits are the two most common work-linked residence permits for foreign nationals employed in Switzerland. The choice between them is often determined by contract duration, but it also carries significant consequences for employer mobility, family reunification, and the path to permanent residence.

The practical significance of the L-versus-B distinction is greatest for non-EU/EFTA nationals. An L permit holder has no right to change employer, cannot pursue self-employment, cannot bring family members to Switzerland, and cannot accumulate years toward a C permit. For anyone intending to build a longer-term presence in Switzerland, the B permit is the correct instrument from the outset, provided the employment contract is open-ended or longer than 12 months.

Transitioning from L Permit to B Permit

When employment continues beyond the 12-month period covered by an L permit, the employer and employee must apply for a B permit before the L permit expires. The process differs by nationality.

EU/EFTA Nationals: Entitlement-Based Transition

EU/EFTA nationals are entitled to a B permit as of right when employment continues beyond the period covered by an L permit. The employer applies to the cantonal Migrationsamt, provides a new or extended employment contract, and the B permit is issued for a 5-year term (or the remaining contract duration if less than 5 years). No quota is consumed and no priority check is required. The transition should be initiated 6 to 8 weeks before the L permit expiry date to avoid any gap in residence authorisation.

Non-EU/EFTA Nationals: Quota-Dependent Transition

For third-country nationals, the transition from L to B permit requires a new application that consumes a B permit quota allocation. The priority check must be satisfied again. The employer submits the application to the cantonal Migrationsamt and obtains cantonal labour office approval before SEM issues the permit. The timeline from application to B permit issuance is typically 8 to 12 weeks. Applications should be submitted at least 10 to 12 weeks before the L permit expires. If the application is pending and the L permit expires, the holder may face an interruption in their work authorisation. Cantonal practice varies on whether interim working rights are recognised during a pending B permit application.

Founders and executives who anticipate that their Swiss engagement will extend beyond 12 months should discuss with their legal advisor whether it is more efficient to apply for a B permit from the outset rather than accepting an L permit and transitioning later. For Swiss company formation clients who also need to establish Swiss residency, the B permit application and company registration are often coordinated in parallel.

Required Documents and Application Process

The L permit application is employer-initiated in almost all cases. The application is submitted to the cantonal migration authority (Migrationsamt) of the canton where the employer's registered place of business is located.

Required Documents (Standard Checklist)

• ●Completed cantonal permit application form (via EasyGov.swiss or cantonal portal)
• ●Valid passport of the applicant (copy, all pages)
• ●Recent biometric passport photograph
• ●Signed fixed-term employment contract (stating start date, end date, position, salary)
• ●Evidence of professional qualifications (degree certificates, CV) for skilled-worker positions
• ●Proof of Swiss residential address (rental agreement or employer-provided accommodation confirmation)
• ●For non-EU/EFTA nationals: priority check documentation (job advertisement records, list of candidates considered, reasons for selecting the third-country national)
• ●Cantonal permit fee: varies by canton and permit category (roughly CHF 65 for EU/EFTA permits, up to about CHF 95 for third-country biometric permits) — confirm the current amount with the relevant Migrationsamt

EU/EFTA Short-Term Notification (Under 3 Months)

For EU/EFTA nationals on assignments of up to 90 days, no permit is required. The employer submits an 8-day advance notification through EasyGov.swiss. The notification records the worker's identity, the assignment start date, the employer's details, and the occupation. The worker may begin the assignment after the 8-day period has elapsed (or after explicit cantonal acknowledgement if the cantonal authority confirms receipt earlier). There is no permit card and no fee for this category.
