Employment & HR Compliance for Swiss Foundations (2026): Hiring, Payroll, Secondments & Social Security

Foundation employment Switzerland has become one of the most pressing compliance topics for foundation boards, family offices and philanthropists entering 2026, as supervisory authorities tighten expectations around governance, beneficial ownership and anti-money-laundering (AML) controls. A Swiss foundation that engages staff, whether a part-time coordinator, a salaried CEO or a seconded executive from a donor company, must navigate a web of employment, payroll, social security and reporting duties that few philanthropic entities were built to handle. The 2026 supervisory environment places documentation, internal control and formalised HR arrangements under closer review than ever before.

This guide sets out, in practical terms, how foundations can hire compliantly, meet payroll and social security obligations, structure secondments, and build the governance safeguards supervisors now expect.

Who this is for: foundation boards, family offices, philanthropists, foundation CEOs, trustees and in-house counsel. Purpose: a practical, actionable legal checklist for hiring staff, payroll compliance, secondments and social security obligations for Swiss foundations, updated for the 2026 supervisory context.

Can a Swiss foundation employ staff? Employees vs volunteers vs service providers

The short answer to the most common question, can a Swiss foundation legally employ staff or must it rely on volunteers or service providers?, is that a Swiss foundation can employ staff directly. A foundation is a legal person under Swiss law and, as such, it has the capacity to enter into contracts, including employment contracts governed by the Swiss Code of Obligations. The practical challenge is not whether it may employ, but how to structure that employment so that payroll, social security and supervisory obligations are met correctly from day one.

Legal capacity of foundations to hire

A foundation established under the provisions of the Swiss Civil Code (Articles 80 et seq. ) is a distinct legal entity with its own assets dedicated to a defined purpose. Because it possesses legal personality, it can act as an employer, sign employment contracts, register with social security institutions and assume employer liabilities. The employment relationship itself is governed by the general employment-contract provisions of the Code of Obligations, the same statutory regime that applies to commercial employers. In other words, foundation employment Switzerland is not a special category of labour law, it is ordinary Swiss employment law applied within a supervised, purpose-bound vehicle.

The distinction matters for governance: the foundation board remains responsible for ensuring that hiring decisions serve the foundation’s purpose and are properly minuted, delegated and documented.

Volunteers and unpaid helpers, limits and risks

Many foundations rely heavily on volunteers, and unpaid voluntary work is entirely legitimate. The risk arises when a “volunteer” receives regular payments, benefits in kind, expense reimbursements that exceed actual costs, or works under instruction in a way that resembles salaried employment. Where the substance of the relationship is employment, Swiss social-security authorities will treat it as such regardless of the label used. Misclassifying an employee as a volunteer can trigger retroactive social security contributions, interest and reputational exposure during supervisory review.

Outsourcing and service providers vs employment, when to choose which

Foundations frequently engage external service providers, accountants, grant administrators, communications consultants, under service or mandate agreements rather than employment contracts. This can be entirely appropriate where the provider is genuinely independent, bears its own business risk, serves multiple clients, and is not integrated into the foundation’s organisation under direct instruction. The decisive factors for Swiss authorities are the degree of subordination, economic dependence and integration, not the title on the contract. If a “consultant” works exclusively for the foundation, follows its instructions, has set hours and uses its resources, authorities may reclassify the relationship as dependent employment and demand employer social security contributions.

The safe course is to choose the structure that matches the economic reality: genuine independence supports a service agreement; integration and subordination point to an employment contract. Getting this right is central to compliant foundation employment Switzerland practice, because misclassification is one of the most common findings in supervisory and social-security audits.

Employment contracts for foundations, mandatory terms, director vs employee status

Once a foundation decides to hire directly, the employment contract is the central compliance document. It should reflect the statutory minimums of the Code of Obligations while also addressing the governance-specific concerns that distinguish foundation employment from ordinary commercial hiring, conflicts of interest, confidentiality of beneficiary data, AML checks and the treatment of board members who also take on executive roles.

Statutory minimums under the Code of Obligations

Swiss employment contracts need not always be in writing, but written contracts are strongly recommended for foundations to satisfy supervisory and audit expectations. The Code of Obligations sets out default rules on several mandatory and semi-mandatory terms, including the probationary period, notice periods, continued salary payment during illness, holiday entitlement and working-time protections. Notice periods and probation vary according to the length of service and what the parties agree within statutory limits, so the contract should state them explicitly. For foundations, clarity on these terms is not merely good employment practice, it also demonstrates to the supervisory authority that the board has approached hiring in a structured, documented manner.

The written contract should specify the role, remuneration, start date, working hours, holiday entitlement, probation, notice and the governing law, and should be approved and minuted at board level where the role is senior.

Special considerations for foundation directors and CEOs

The status of foundation directors and senior officers requires careful analysis. A foundation board member who performs only governance functions is generally not an employee; their relationship is organic and fiduciary. However, where a board member or officer also takes on executive, day-to-day operational responsibility, for example, a managing director or CEO who runs the foundation under the board’s supervision, that executive relationship may constitute employment, with corresponding payroll and social security consequences. Dual roles must be handled transparently. Conflict-of-interest principles demand that any director who is also remunerated as an employee abstain from decisions on their own compensation, that the board documents the arm’s-length basis of the remuneration, and that the arrangement is consistent with the foundation’s purpose.

The Swiss Federal Supreme Court has repeatedly addressed the characterisation of employment status and director duties, and foundations should expect supervisors to scrutinise remunerated board members closely. Professional-conduct standards also inform how conflicts and independence are managed where advisers sit on, or advise, foundation boards.

Sample clause highlights (illustrative only, verify with counsel)

The following clause themes are commonly addressed in foundation employment contracts. They are illustrative only and should not be relied upon without local counsel.

• Remuneration. State gross salary, payment frequency, any thirteenth-month entitlement, and confirm that remuneration is subject to statutory withholdings and employer social security contributions.
• Confidentiality. Bind the employee to protect beneficiary, donor and grantee information both during and after employment, reflecting the sensitivity of philanthropic data.
• AML and integrity checks. Require the employee to cooperate with beneficial-ownership and AML due-diligence procedures and to disclose circumstances relevant to the foundation’s compliance obligations.
• Intellectual property. Assign to the foundation rights in work product created in the course of employment, subject to statutory limits.
• Conflicts of interest. Require disclosure of outside interests and prohibit the employee from acting where personal interests conflict with the foundation’s purpose.

A key point on tax treatment: a director who is only a board member is taxed and treated differently from a director who is also an employee. Executive remuneration flowing through payroll attracts withholding (where applicable) and social-security contributions, whereas pure board fees are treated under separate rules. The contract and the payroll set-up must reflect which category applies.

Foundation payroll Switzerland, tax withholding, employer contributions and reporting

Once staff are engaged, the foundation becomes an employer for payroll and social security purposes. This is where many foundations underestimate the administrative burden. Running foundation payroll Switzerland correctly means registering with the relevant social-security institutions, calculating and withholding the right contributions, managing accident and occupational-benefit cover, and reporting accurately to the tax and social-insurance authorities. The question foundations most often ask, what employment contract and payroll obligations does a Swiss foundation have in respect of tax, social security and insurance?, is answered across the three regimes below.

AHV/IV/EO and ALV employer contributions

Every Swiss employer, including a foundation, must affiliate with a compensation office (Ausgleichskasse / caisse de compensation) and register its employees for the first-pillar social insurances. These comprise old-age and survivors’ insurance (AHV), disability insurance (IV) and the income-compensation scheme (EO), together with unemployment insurance (ALV). Contributions are split between employer and employee, with the employer deducting the employee’s share from gross salary and paying both shares to the compensation office, along with its own employer contribution. The Federal Social Insurance Office (FSIO) and the compensation offices publish the applicable contribution rules and rates, and foundations should confirm the current figures and registration steps directly with their compensation office, as rates and thresholds are reviewed periodically.

The practical first step for any new employer foundation is to register with a compensation office before the first salary payment, so that contributions are captured from the outset and no retroactive liability accrues.

Withholding tax vs final taxation for foreign and cross-border employees

Tax treatment depends on the residence and status of the employee. Swiss-resident employees with a settlement permit (C permit) or Swiss nationality are generally assessed and taxed on an ordinary basis, whereas many foreign employees without settled status are subject to withholding tax (Quellensteuer / impôt à la source) deducted directly from salary by the employer. Cross-border workers and non-resident employees have their own withholding regimes, and the applicable cantonal rates and procedures must be confirmed. The Swiss Federal Tax Administration (FTA) and the cantonal tax authorities provide guidance on payroll withholding, employer reporting duties and the treatment of non-resident and cross-border employees.

Foundations employing international staff, common in the philanthropic sector, must determine for each employee whether withholding applies, apply the correct cantonal tariff, and remit and report the withheld tax to the relevant authority. Getting cross-border withholding wrong is a frequent source of employer liability, so this element of foundation employment Switzerland deserves early attention with the foundation’s accountant.

Accident insurance and occupational benefits

Swiss employers must insure their staff against accidents. Employees are covered for occupational accidents and, where they work sufficient hours, for non-occupational accidents as well. Accident insurance is provided either through the Swiss National Accident Insurance Fund (Suva) or, depending on the sector and activity, through a private insurer; Suva and the relevant authorities set out employer duties, the scope of mandatory cover and registration requirements. The occupational-accident premium is borne by the employer, while the non-occupational premium is typically charged to the employee. Separately, the occupational pension scheme, the second pillar under the Federal Act on Occupational Old Age, Survivors’ and Invalidity Pension Provision (BVG/LPP), becomes mandatory once an employee’s salary exceeds the statutory entry threshold.

The foundation must affiliate with a pension institution and pay employer contributions alongside the deducted employee share. Together, AHV/IV/EO, ALV, accident insurance and BVG form the core of a foundation’s social security footprint as an employer.

Foundation payroll Switzerland, set-up checklist:

• Register with a compensation office for AHV/IV/EO and ALV before the first salary payment.
• Affiliate with a BVG pension institution for employees above the statutory salary threshold.
• Arrange accident insurance (Suva or private insurer) and register employees.
• Determine withholding-tax status for each employee and apply the correct cantonal tariff.
• Set up a payroll provider or accountant to calculate deductions, issue salary statements and file returns.
• Produce annual salary certificates (Lohnausweis / certificat de salaire) for employees and the tax authorities.
• Retain payroll records, contracts and board approvals for audit and supervisory review.

Secondments and intercompany service agreements when donors provide staff

A distinctive feature of the foundation sector is that founders, donors and group companies often provide personnel to the foundation rather than the foundation hiring directly. This raises a practical question: how do secondments and intercompany service agreements work when a donor company provides staff to a foundation, and who bears the social security and tax burden? The answer turns on how the arrangement is legally structured.

Legal structure: secondment vs service agreement vs loan of personnel

There are three broad models. Under a secondment, the donor company remains the formal employer and places an employee at the foundation’s disposal for a defined period, usually under a secondment agreement between the two entities. Under a service agreement, the donor provides a service (for example, administrative support) and retains full employer control over its staff, who are not integrated into the foundation. Under a formal loan or hiring-out of personnel, staff are placed with the foundation under the donor’s employment but the foundation directs their day-to-day work, an arrangement that in some circumstances engages the Swiss Recruitment Act (AVG/LSE) rules on the hiring-out of workers, which may require authorisation.

The choice affects who exercises direction, who carries employer liabilities, and how costs are recharged. Each secondment to a foundation Switzerland arrangement should be documented in writing, specifying duration, reporting lines, cost allocation and liability.

Social security and tax implications for seconded staff

Where a donor company remains the formal employer under a secondment, that company generally continues to run payroll, deduct and remit social security contributions, and maintain accident cover, recharging the cost to the foundation. For purely domestic secondments this is relatively straightforward. For cross-border secondments the position is more complex: continued affiliation to the home-country social-security system may be possible under applicable coordination rules (such as the EU/EFTA coordination regulations via an A1 certificate, or the terms of a bilateral social security agreement) for a limited period, but this must be confirmed and documented, and the tax treatment of the seconded employee’s remuneration must be analysed to determine whether Swiss withholding applies.

The foundation should obtain confirmation of which entity carries each obligation, AHV, accident insurance, withholding tax, and reflect that allocation in the secondment agreement so there is no gap in cover or contributions.

Practical clauses: secondment agreement checklist

A robust secondment agreement for a foundation should address, at minimum, the items below. These are illustrative only and should be tailored with counsel.

• Parties and employer status. Confirm which entity remains the formal employer and retains payroll and social-security responsibility.
• Duration and renewal. State the secondment period and any extension mechanism.
• Direction and reporting. Define who gives day-to-day instructions and to whom the secondee reports.
• Cost allocation. Specify salary, social-security and insurance recharges between donor and foundation.
• Social security and tax. Allocate responsibility for AHV, accident insurance, BVG and withholding tax, and reference any cross-border coordination certificate.
• Work permits. Confirm that any required permit or notification is in place before the secondee begins work in Switzerland.
• Confidentiality and conflicts. Bind the secondee to the foundation’s confidentiality and conflict-of-interest standards.
• Indemnity. Address liability and indemnification between the donor and the foundation for acts of the secondee.

For cross-border arrangements, the foundation must also consider Swiss immigration requirements. Foreign nationals from outside the EU/EFTA generally require a work permit, and even EU/EFTA nationals may face notification or permit formalities depending on the length and nature of the posting. Engaging a payroll agency or local counsel early avoids the common pitfall of a secondee starting work before permits and social-security coverage are confirmed.

Supervisory, AML and reporting risks, governance safeguards for foundations

The 2026 context is defined by heightened supervisory scrutiny. Foundations should ask directly: what are the supervisory and reporting risks if foundation staff receive remuneration or benefits? The answer is that remuneration and benefits are precisely the areas supervisors examine most closely, because they can indicate self-dealing, misuse of foundation assets, or inadequate internal control. Building sound governance around HR and payroll is therefore central to defensible foundation employment Switzerland practice.

2026 supervisory expectations, beneficial ownership, AML and internal control

Swiss foundations are subject to supervisory oversight, classic charitable foundations by the Federal Supervisory Authority for Foundations or the competent cantonal authority, and occupational-benefit foundations by the relevant pension supervisory authorities. The direction of travel for 2026 is toward more formalised governance, expanded beneficial-ownership transparency and stronger AML controls. The practical effect for employers is that boards are increasingly expected to demonstrate documented internal controls, clear delegation of authority, and verifiable due diligence on the people they engage and remunerate. Foundations with informal, undocumented HR arrangements can expect closer review, while those with written contracts, board-approved remuneration and clear records will be better placed to satisfy inspections.

How staff remuneration and benefits can trigger supervisory review

Certain features reliably draw supervisory attention: remuneration paid to board members, benefits flowing to persons close to the founder, compensation that appears disproportionate to the role or to the foundation’s purpose, and payments lacking a documented contractual basis. Where any of these appear, supervisors may ask the board to justify the arrangement, demonstrate that it serves the foundation’s purpose, and show that conflicted individuals did not decide on their own pay. Undocumented or above-market remuneration is one of the clearest triggers for intervention.

Recommended governance safeguards

To withstand supervisory and AML review, foundations should put in place a structured set of HR governance safeguards:

• Written HR policy. Adopt a board-approved policy covering hiring, remuneration, conflicts and record-keeping.
• Delegated authority matrix. Define who may approve hires, salaries and secondments, and at what level board approval is required.
• Documented remuneration decisions. Minute the basis for all remuneration, confirming arm’s-length pricing and the abstention of any conflicted director.
• AML and beneficial-ownership checks. Apply due diligence consistent with 2026 expectations to employees, secondees and service providers in sensitive roles.
• Complete payroll records. Retain contracts, salary certificates, social-security registrations, insurance confirmations and board approvals.
• Audit trail. Keep an accessible record linking each engagement to a board decision, a contract and a payroll entry.

Practical checklist, steps for a foundation to set up compliant HR and payroll

1. Decide the engagement model using a decision tree: direct employment, secondment from a donor, or an independent service provider, chosen by economic reality, not label.
2. Prepare a written contract or agreement with the mandatory terms, approved and minuted at board level for senior roles.
3. Register with a compensation office for AHV/IV/EO and ALV before the first payment.
4. Affiliate with a BVG pension institution where the salary threshold is met.
5. Arrange accident insurance (Suva or private insurer) and register all staff.
6. Determine withholding-tax status for each employee and apply the correct cantonal tariff.
7. Onboard a payroll provider to run deductions, issue salary certificates and file returns.
8. Confirm work permits or notifications for any foreign national before they start.
9. Document delegated authority, remuneration rationale and conflict-of-interest clearance.
10. Retain all records for audit and supervisory inspection.

The snapshot below compares the main obligations and risks across the four engagement models. It is a guide only; the correct treatment depends on the facts of each arrangement.

Conclusion

Compliant foundation employment Switzerland in 2026 is no longer a matter of informal goodwill. With supervisory authorities expecting formalised governance, expanded beneficial-ownership transparency and robust AML controls, foundations must treat hiring, payroll, secondments and social security as core compliance functions. The practical path is clear: choose the engagement model that matches economic reality, document every contract and remuneration decision at board level, register promptly for AHV/IV/EO, ALV, accident insurance and BVG, apply the correct withholding regime to each employee, and build an audit trail that will satisfy any inspection. Foundations that formalise HR compliance now will be well placed to meet the supervisory expectations ahead; those relying on undocumented arrangements face the greatest risk.

For tailored employment contracts, secondment templates and a full compliance review, foundations should seek specialist legal advice. You can also explore the Foundations practice area, Switzerland and the GLE lawyer directory: Foundations, Switzerland to find suitable counsel.
