Business expenses in Switzerland explained simply
Many self-employed people and small businesses ask which expenses belong to the business and which do not.
This article is for educational and informational purposes only. You do not need bookkeeping knowledge. The examples below deliberately use general roles and placeholders such as Amount X and Amount Y.
The goal is to explain typical business costs in plain language, show common mistakes and make clear why receipts, documentation and separating private from business spending matter.
What are business expenses?
Business expenses are costs that arise in connection with a business activity.
What matters is the business purpose. If a company needs something for operations, customer work or organization, that item can be business-relevant.
For bookkeeping, the key point is that such expenses are documented and recorded in a traceable way.
Which expenses are often recorded as business expenses?
Many cost categories appear again and again in day-to-day work. The overview below shows typical examples without making a binding assessment.
| Category | Typical examples |
|---|---|
| Office | Rent, utilities, office supplies or small consumables for everyday work. |
| Work equipment | Devices, tools or materials a company uses in daily operations. |
| Software | Accounting software, cloud services, communication tools or industry-specific applications. |
| Phone | Business-related phone costs or mobile communication connected to customers and projects. |
| Internet | Internet access or data connections used for business activity. |
| Training | Courses, seminars or professional training related to a company's activity. |
| Marketing | Website, ads, printed materials, online campaigns or presentation material. |
| Insurance | Insurance policies with a direct link to the business or its risks. |
| Advisory services | Fiduciary support, external advice or other specialist services. |
| Bank fees | Account charges, payment fees or charges from financial service providers. |
| Business travel | Trips, travel costs or accommodation directly connected to business appointments. |
| Professional literature | Books, magazines or digital sources relevant to the business activity. |
Why is it important to separate private and business spending?
Separating private and business spending is important so your bookkeeping remains traceable.
If a company mixes private and business payments, it later becomes unclear which costs really belong to the business. That weakens visibility and increases the risk of mistakes.
Clean separation helps with documentation, ongoing recording and year-end preparation.
What role do receipts play?
Receipts are the proof that a business transaction actually took place.
They show, for example, who provided a service, when something was purchased and how the transaction was described.
That is why receipts are central for order and traceability.
Home office, phone and internet: why these areas often raise questions
These areas often raise questions because they are frequently used in a mixed way.
With home office, phone and internet, not everything is clearly only private or only business. That is exactly why documentation matters so much.
This article does not provide individual recommendations. The concrete treatment can vary depending on the case. The concrete tax treatment depends on the individual situation and the applicable rules. If in doubt, a specialist should be consulted.
Typical mistakes with business expenses
Many problems do not come from complex rules, but from missing routine.
Losing receipts
Without receipts, the basis for clean documentation is missing.
Recording private expenses
If private transactions enter business bookkeeping, the overview becomes unclear.
Forgetting cash expenses
Small outlays are easily missed if they are not captured immediately.
No documentation
A bank line alone often does not explain what really happened.
Mixing business and private accounts
Mixed account movements make later assignment unnecessarily difficult.
Not recording expenses regularly
If you wait too long, you lose context and overview more quickly.
