Mortgage for self-employed in Switzerland

Obtaining a mortgage as a self-employed person in Switzerland is entirely achievable, but the process is more demanding than for an employee. Variable income, thorough accounting documentation, and increased equity: this guide details the conditions, required documents, and strategies to maximize your chances of securing financing for your property.

Why is it more complicated for the self-employed?

Banks assess the risk of each mortgage application. For an employee, income is stable, documented by payslips, and guaranteed by an employment contract. For a self-employed person, the situation is fundamentally different:

  • Variable income: Revenue and net profit fluctuate from year to year, complicating the assessment of sustainable affordability
  • No employment contract: No salary certificate or employer guarantee
  • Entrepreneurial risk: The business may face difficult periods or even cease operations
  • Tax optimization: Many self-employed individuals optimize their taxable income (deductions, provisions), which reduces the declared income considered by banks
  • Often incomplete pension provision: No mandatory 2nd pillar (LPP/BVG) for sole proprietorships, fewer social safety nets

For these reasons, banks apply stricter criteria and request more documentation. But this does not mean homeownership is out of reach -- far from it.

Key conditions for obtaining a mortgage as self-employed

Minimum activity duration: 3 years

The vast majority of banks require a minimum of 3 years of self-employment. This period provides three complete fiscal years and demonstrates business viability. Some banks accept 2 years in exceptional cases (buoyant sector, prior experience in the field, strong revenue growth), but this is rare.

If your business is less than 3 years old, you can still build a case with a solid business plan, client reference letters, and ideally, proof of prior income in the same field as an employee. A mortgage broker can identify the institutions most open to young businesses.

The last 3 tax returns

The tax returns for the last 3 fiscal years form the basis of the financial analysis. They allow the bank to verify the effectively declared income, net wealth, any debts, and the overall financial profile's consistency. Final tax assessments are preferred over provisional declarations.

Financial statements and income statements

In addition to tax returns, banks request balance sheets and income statements (profit and loss) for the last 3 fiscal years. These documents allow assessment of:

  • Revenue and its evolution
  • Net profit after deduction of expenses
  • Cost structure and margins
  • Business financial health (liquidity, debt, business equity)
  • Regularity of results from year to year

Financial statements certified by a fiduciary (accounting firm) significantly strengthen the application's credibility.

How do banks calculate a self-employed person's income?

Income calculation is the central point of the assessment. Unlike an employee whose gross annual income is directly readable, a self-employed person's income requires in-depth analysis.

The standard method: 3-year average

Most banks calculate the average net income over the last 3 fiscal years. Some adopt an even more conservative approach by excluding the best year and retaining only the average of the two lowest years, or simply taking the lowest income of the three.

Concrete example

A self-employed architect declares the following net incomes:

  • Year 1: CHF 120,000
  • Year 2: CHF 95,000
  • Year 3: CHF 140,000

Simple average: CHF 118,333

Average excluding the best year: CHF 107,500 (used by some banks)

It is this latter amount that will be used for the affordability calculation, with the usual theoretical 5% rate.

The trend matters

A rising income trajectory is a very positive signal for banks. Conversely, declining income, even if the average remains adequate, can lead to rejection or unfavorable conditions. If your income experienced a temporary dip (illness, loss of a major client, sector-specific downturn), prepare a documented explanation.

Income for different legal forms

Income treatment differs by legal form of the business:

Legal form Income considered Specifics
Sole proprietorship Net business profit Most common; personal and business assets/liabilities are combined
LLC (Sarl/GmbH) Salary paid + possibly regular dividends Bank also examines LLC accounts to ensure salary sustainability
Ltd. (SA/AG) Salary paid + documented dividends Treatment similar to employee if salary is regular and documented with payslips

For LLC or Ltd. directors, banks may treat the application more favorably if a regular fixed salary is paid and documented with monthly payslips. In this case, the profile approaches that of an employee. This is an important strategic element to consider when choosing a legal form.

Equity: often increased requirements

Although the legal minimum is 20% equity (of which 10% in "hard" equity), the reality for the self-employed is different. Most banks require 25% to 30% to compensate for the perceived risk.

Profile Min. equity Of which "hard" Max. LTV
Employee (reference) 20% 10% 80%
Self-employed (sole proprietorship) 25-30% 15-20% 70-75%
LLC/Ltd. director (regular salary) 20-25% 10-15% 75-80%

Worked example

For a property worth CHF 900,000:

  • An employee needs CHF 180,000 in equity (20%)
  • A self-employed sole proprietor needs CHF 225,000 to 270,000 (25-30%)
  • That is CHF 45,000 to 90,000 in additional equity

Required documents: the complete checklist

A well-prepared application is essential to convince the bank. Here is the comprehensive list of documents to gather:

Personal documents

  • ID card or passport
  • Residence permit (if applicable)
  • Debt collection office extract (less than 3 months old)
  • Civil status and matrimonial regime

Tax and accounting documents

  • Last 3 complete tax returns with tax assessments
  • Balance sheets for the last 3 fiscal years
  • Income statements (profit and loss) for the last 3 fiscal years
  • AVS/AHV attestation (contributions paid)
  • Compensation fund attestation

Business documents

  • Commercial register extract (if registration is mandatory)
  • Significant ongoing contracts (regular clients, framework agreements)
  • Business plan (if business is less than 3 years old)
  • Professional liability insurance certificate

Pension documents

  • 2nd pillar (LPP/BVG) attestation (if voluntarily affiliated or via LLC/Ltd.)
  • Pillar 3a attestations (bank and/or insurance)
  • Savings and wealth statements

Property documents

  • Property description, plans, photos
  • Value estimate or agreed sale price
  • Land registry extract

Legal forms and bank treatment

Sole proprietorship (Einzelunternehmen/entreprise individuelle)

This is the most common form among self-employed individuals in Switzerland and also the most complex from a banking perspective. Personal and business assets are combined, meaning business debts directly affect the borrower's profile. The net profit declared for tax purposes serves as the income calculation basis.

Advantage: Simplicity of management, no double taxation.
Disadvantage: Income often tax-optimized (and therefore low in the bank's eyes), no mandatory 2nd pillar, unlimited liability that weighs on the risk assessment.

LLC (Sarl/GmbH)

The director-shareholder of an LLC is employed by their own company. They pay themselves a monthly salary documented by payslips, which reassures banks. Liability is limited to the share capital (minimum CHF 20,000).

Advantage: Regular salary treated as employee income, access to mandatory 2nd pillar, limited liability.
Disadvantage: The bank will verify that the LLC can sustain the salary long-term; dividends are sometimes excluded from the income calculation.

Ltd. (SA/AG)

Treatment is similar to the LLC. If the director pays themselves a fixed, regular salary, the application can be treated almost like a standard employee's. The Ltd. offers the best image of stability in banks' eyes, but involves higher management costs (minimum capital CHF 100,000).

Which banks accept self-employed applicants?

Not all institutions treat self-employed applications the same way. Differences in approach are significant:

  • Cantonal banks: Some are relatively open to self-employed applicants, especially if the borrower is a well-established local entrepreneur. Knowledge of the regional economic fabric is an asset.
  • Major national banks: They have standardized processes that sometimes leave little room for atypical profiles. The application must be solid and fit the automated criteria.
  • Raiffeisen banks: Their local anchoring and knowledge of regional SMEs can work in favor of the self-employed.
  • Insurance companies: Swiss Life, Allianz, Pax, and other insurers offer mortgages with sometimes more flexibility on acceptance criteria, in exchange for slightly higher rates.
  • Pension funds: Some pension funds invest in mortgages and may accept mixed profiles.

Using a mortgage broker is particularly relevant for the self-employed. The broker knows each bank's policies and can submit the application to the institutions most likely to accept it, avoiding multiple rejections that can harm the application.

Strategies to maximize your chances

1. Build substantial equity

The higher your down payment, the more banks will be inclined to accept your application. A contribution of 30% or more reduces the LTV and therefore the risk for the bank. Start saving systematically as early as possible, including via pillar 3a, which offers a double advantage: tax deduction and equity building.

2. Opt for indirect amortization via pillar 3a

Indirect amortization is particularly advantageous for the self-employed. Instead of directly repaying the mortgage principal, you pay the amount into a pillar 3a. This strategy allows you to:

  • Deduct mortgage interest from taxable income
  • Also deduct pillar 3a contributions
  • Build pension savings (crucial when self-employed)
  • Maintain higher fiscal debt, thus a reduced tax burden

Reminder: as a self-employed person without a 2nd pillar, you can contribute up to 20% of your net income (capped at CHF 36,288 in 2026) to pillar 3a -- significantly more than the cap for employees affiliated with a 2nd pillar (CHF 7,258).

3. Present solid and transparent financial statements

Avoid excessive tax optimization in the 2-3 years before your mortgage application. An artificially low declared income will be taken at face value by the bank. Discuss with your fiduciary (accountant) the balance between tax optimization and income presentation with a property project in mind.

4. Have your accounts certified by a fiduciary

Accounts reviewed or at least prepared by a recognized fiduciary add credibility to the application. The bank will have more confidence in figures validated by a professional than in self-managed bookkeeping.

5. Document your contracts and order book

If you have framework contracts with regular clients, multi-year mandates, or a full order book, provide these elements. They demonstrate that your business generates recurring and predictable income.

The mixed couple: one employee and one self-employed

When a couple consists of one employee and one self-employed person, banks adopt a more favorable approach. The employee spouse's fixed salary provides the stability the bank seeks, while the self-employed person's income supplements the overall affordability.

Example: mixed couple

Marie is a bank employee with a gross salary of CHF 95,000 per year. Pierre is a self-employed graphic designer with an average net income of CHF 75,000 over 3 years.

Combined income considered: CHF 95,000 + CHF 75,000 = CHF 170,000

With a theoretical 5% rate, annual charges must not exceed one-third of income, i.e., CHF 56,667.

This couple could finance a property of approximately CHF 850,000 with 20% equity -- conditions close to those for a couple of employees. Use our mortgage simulator to estimate your own capacity.

In this configuration, banks typically require the standard documentation for the employee (payslips, salary certificate) and full documents for the self-employed person (tax returns, financial statements). Equity conditions are often relaxed compared to a couple of two self-employed individuals.

Common mistakes to avoid

  • Applying for a mortgage too early: Before 3 years of activity, chances of success are low. Wait and build a solid application.
  • Over-optimizing taxes: Very low declared income may be good for the tax authorities but disastrous for the mortgage application.
  • Multiplying applications after rejection: Each rejected application leaves a trace. Better to target the right banks from the start with a broker's help.
  • Neglecting pension provision: Well-structured pension savings (maximized pillar 3a, voluntary 2nd pillar if possible) reassures the bank and builds equity.
  • Mixing personal and business finances: Separate accounts and clear bookkeeping facilitate the bank's analysis.
  • Forgetting ancillary costs: Beyond equity, budget for notary and purchase costs representing 3% to 5% of the property price depending on the canton.

SARON or fixed rate: which choice for a self-employed person?

The choice between SARON (Swiss Average Rate Overnight) and a fixed rate deserves particular thought for the self-employed:

  • Fixed rate: The security of fixed monthly payments is a major advantage when income fluctuates. You know exactly what you will pay each month, which makes cash flow management easier. This is the preferred choice for many self-employed individuals.
  • SARON: The rate is generally lower, but it varies. If your business generates income comfortable enough to absorb a rate increase, SARON can save you money over time.
  • Tranche strategy: Combining part at a fixed rate (for security) and part at SARON (for savings) can be a good compromise.

The role of a mortgage broker for the self-employed

For the self-employed, using a mortgage broker is not a luxury -- it is a strategic investment. Here is why:

  • Knowledge of bank policies: The broker knows exactly which banks accept self-employed profiles and under what conditions
  • Application optimization: They help you present your income and business in the best light, without falsifying anything
  • Time savings: Instead of approaching 10 banks yourself, the broker directly targets the 3-4 most relevant institutions
  • Rate negotiation: Thanks to the volume of applications handled, the broker often obtains preferential conditions
  • Free service for the borrower: The broker is paid by the bank, not by you
