Owner Contributions in Your Swiss Business
You're investing personal money into your business. Is it income? No. But how do you record it correctly? The answer surprises many new founders.
You're recording it wrong – or not at all.
Both can be correct.
Owner contributions confuse almost every new entrepreneur. This article explains what's behind it – and what you actually need to enter in your bookkeeping.
Personal Contribution

Record it correctly – in 2 minutesWhat is an owner contribution?
An owner contribution (German: Privateinlage) occurs when you, as the sole proprietor, inject personal money into your business – for example to pay for office supplies, software, or other business costs.
This happens most often during the startup phase, before customer revenue starts flowing in.
The most important point: An owner contribution is not income and must not be recorded as revenue. It does not increase your profit and has no impact on your taxes.
Why isn't it income?
In a Swiss sole proprietorship (Einzelfirma / raison individuelle / ditta individuale), you and your business are legally the same person. There is no legal separation like with an LLC (GmbH/Sàrl) or corporation (AG/SA). When you transfer money from your personal account to your business account, you're essentially moving money from one pocket to the other.
Your taxable income as a self-employed person is the profit of the business (revenue minus expenses) – not the capital you contributed.
How do you record an owner contribution?
It depends on the type of bookkeeping you use.
Simple bookkeeping (cash-basis accounting)
This is the most common form for Swiss freelancers with revenue under CHF 500,000.
Answer: You don't. You don't record the owner contribution itself. You only record the business expense that results from it.
Example: You pay CHF 200 for office supplies with your personal credit card.
- ✗ You record: CHF 200 owner contribution (income) → Wrong
- ✓ You record: CHF 200 office supplies (expense) → Correct
The owner contribution itself – the transfer from your personal to your business account – does not appear anywhere in your books. This is perfectly correct.
Double-entry bookkeeping
Those using double-entry bookkeeping (mandatory above CHF 500,000 revenue) record owner contributions to the equity account (private account):
| Debit | Credit |
|---|---|
| Cash / Bank | Equity (private account) |
The contribution appears as an equity inflow – not as revenue.
What about owner withdrawals?
The opposite – when you take money out of the business for personal use – works the same way:
- Simple bookkeeping: The withdrawal itself is not recorded. If you use business money for personal expenses, do not record it as a business expense.
- Double-entry: Debit Equity (private account) / Credit Bank.
Common mistakes
❌ Recording the owner contribution as income This artificially inflates your profit and you pay too much tax.
❌ Recording personal expenses as business expenses Only costs with a direct link to your professional activity are deductible.
❌ Mixing personal and business finances A separate business bank account makes everything easier – including for your accountant.
In Magic Heidi
In Magic Heidi (simple bookkeeping), you enter the expense directly – not the owner contribution. Choose the appropriate category (e.g. "Office Supplies", "Software") and enter the amount. Done.
The app doesn't distinguish between "paid with personal money" and "paid with business money" – and neither do you need to. What matters is the expense, not the payment source.
Common Questions About Owner Contributions
Do I need to declare owner contributions in my tax return?
Not separately. Your taxable income as a sole proprietor is the profit of your business. Owner contributions don't factor into the profit calculation and don't need to be declared separately. Your accountant or tax software will automatically calculate the profit from your revenue and expenses.
What if I have a separate business bank account?
Simply transfer from your personal to your business account – and don't record this transfer in simple bookkeeping. Only record the subsequent business expense (rent, supplies, software). In double-entry bookkeeping: Debit Bank / Credit Equity.
Can I take back the owner contribution later tax-free?
In a Swiss sole proprietorship, there is no tax-free capital repayment like in a GmbH. You withdraw your profit – which is taxed as income. A separate equity repayment doesn't exist in this legal structure.
Do I need a business bank account?
It's not legally required. But for clarity – and to avoid exactly this kind of confusion – we strongly recommend a separate business bank account. Beyond a certain revenue threshold, banks will require it anyway.
Does this also apply to contributions in kind (e.g. a laptop)?
Yes. If you put a private device to work for the business, this is also an owner contribution (contribution in kind). The fair market value of the device can be contributed to the business and depreciated accordingly. In simple bookkeeping, the book value is recorded directly as an expense.
