01Why you don't pay yourself a salary
In a sole proprietorship, there is no legal separation between you as a person and your business. You and your company are one. Therefore:
- You are not an employee of your own company
- You don't pay yourself a salary and don't issue a salary certificate
- Your business profit (income minus expenses) flows directly into your taxable income
- In your tax return, you declare this profit under 'Income from self-employment'
02What is a private withdrawal?
When you transfer money from your business account to your personal account, this is called a private withdrawal. And here's the important point:
The same applies in reverse: if you deposit private money into the business account (private contribution), this is not business income.
| Transaction | Booking required? | Why |
|---|---|---|
| Business account → Personal account | No | Private withdrawal, not an expense |
| Personal account → Business account | No | Private contribution, not income |
| Business expense paid from personal account | Yes | Business expense, even if paid privately |
| Private expense paid from business account | No | Private, doesn't belong in bookkeeping |
Important: if you pay a business expense with your personal account (e.g. office supplies), you may and should still record it as a business expense. The receipt counts, not which account was debited.
03How much can you 'pay yourself'?
Theoretically, you can withdraw as much money from the business account as you like at any time — it's your money. But managing wisely means keeping reserves for:
- OASI/DI/APG contributions: 10.6% of your profit (2026), paid directly to the compensation office
- Income tax: Depending on canton and profit, 20–40% of taxable income
- VAT: If you're subject to VAT, set aside the amount owed
- Reserves: For weaker months, investments or unexpected expenses
04Concrete example: From revenue to income
Marco is a self-employed graphic designer in Bern. Here's how his year 2026 looks:
| Item | Amount |
|---|---|
| Annual revenue (income) | CHF 120,000 |
| Business expenses | – CHF 25,000 |
| Business profit (= income) | CHF 95,000 |
| OASI/DI/APG (10.6%) | – CHF 10,070 |
| Pillar 3a (maximum without BVG) | – CHF 36,288 |
| Taxable income (approx.) | CHF 48,642 |
| Income tax (approx. 15%) | – CHF 7,300 |
| Net available (approx.) | CHF 41,342 |
From CHF 120,000 revenue, Marco is left with around CHF 41,000 net — after all deductions, social insurance and taxes. In practice, he has about CHF 3,400 per month available to live on.
05OASI contributions: The 'social contributions' of the self-employed
As an employee, you split the OASI contributions with the employer (5.3% each). As a self-employed person, you bear the full contribution alone — currently 10.6% on your net profit (minus personal contributions).
- You register with the cantonal compensation office
- During the year, you pay provisional contributions based on an estimate
- After submitting your tax return, the final settlement is made — additional payment or refund
- OASI contributions are a business expense and reduce your taxable profit
06What doesn't belong in your bookkeeping?
Since there is no separation between the company and the person in a sole proprietorship, certain things are not business transactions:
| Transaction | In the bookkeeping? |
|---|---|
| Private withdrawal (money to personal account) | No |
| Private contribution (money to business account) | No |
| Rent for private apartment | No (except home office share) |
| Private purchases from business account | No |
| Pillar 3a contribution | No (tax deduction via tax return) |
| Health insurance premium | No (tax deduction via tax return) |
| OASI contributions | Yes — business expense |
| BVG contributions (voluntary) | Yes — business expense |
07Tips for a healthy income
Even though it's not legally required: a separate business account makes your bookkeeping clearer and makes the tax return much easier.
Transfer a fixed amount to your personal account every month. This creates predictability and prevents you from spending too much in good months.
Set up a standing order that automatically transfers 30–40% of every payment received to a tax savings account.
Check every 3 months how your profit is developing. This allows you to react early — whether with savings measures or investments for tax optimisation.
