Balance sheet
Assets and liabilities at the balance sheet date.
Income statement
Expenses and income for the financial year.
Notes
Explanations required by the Code of Obligations.
Optional: cash flow statement and management report
Required for companies that are subject to an ordinary audit by law (Art. 961 CO), otherwise at the request of banks and investors.
AG and GmbH
Legal entities are required to prepare annual financial statements under the Swiss Code of Obligations (OR).
Sole proprietorships from CHF 500,000 turnover
Partnerships above this threshold are also subject to the obligation.
Voluntary annual accounts
Also useful for smaller companies, for example for banks or investors.
AG and GmbH
Always full annual financial statements under the Swiss Code of Obligations: balance sheet, income statement and notes. This applies regardless of turnover and size, and also in the first financial year.
Sole proprietorship (Einzelfirma) with turnover up to CHF 500,000
A statement of income, expenditure and financial position is sufficient, the so-called Milchbüechlirechnung. No notes, no double-entry bookkeeping. You still need it to be clean for the tax return.
Sole proprietorship with turnover from CHF 500,000
Above this threshold, the same rules apply as for legal entities: double-entry bookkeeping and annual financial statements under the Swiss Code of Obligations. The change often comes unexpectedly, because the turnover of a good year counts.
Voluntary, but useful
Anyone looking for financing, wanting to sell a business or bringing partners on board needs reliable figures. Voluntary annual accounts under the Swiss Code of Obligations are the usual basis for this.
Which threshold applies when is explained in detail in the article Accounting obligations in Switzerland (in German). It also explains why CHF 100,000 means something quite different from CHF 500,000 and why the change is almost always noticed a year too late.

Timetable
Annual accounts are not an event in March, but a process over several months. If you take the first step seriously, you will have little trouble with the rest.
Before the balance sheet date, go through the open items, clarify private withdrawals and request missing receipts. An hour in December saves a day in March. In January and February, compile the documents: bank statements as at the balance sheet date, balance confirmations, payroll data and contracts extending beyond the end of the year.
We post the closing entries, reconcile, prepare the balance sheet, income statement and notes, and coordinate the tax return at the same time.
General meeting with approval of the annual financial statements. We supply the draft minutes, so that nothing is forgotten.
The deadline for the tax return is also set by the canton. In the canton of Zurich, legal entities file it by 30 September. Until that date, an extension to 30 November can be requested online. Beyond that, the tax office only grants extensions in exceptional cases and only on written application; heavy workload and missing documents are expressly not accepted as reasons. We file the request for an extension when it becomes necessary and let you know beforehand.
Missing receipts
By far the most common reason. A single supplier invoice that cannot be found can hold up a reconciliation for a week.
Unreconciled bank accounts
If the balance in the accounts does not match the bank statement, the difference has to be found, going back through 12 months.
Open items without clarification
Receivables that have been open for 2 years and payables that were paid long ago: both have to be cleared up before the annual closing.
Private items in the business
Private withdrawals and expenses have to be separated out. The later this happens, the more tedious the allocation becomes.
Contracts nobody knows about
Leasing, loans and rental agreements extending beyond the end of the year. They affect the accruals and often only turn up late.
The tax return done separately
Anyone who has the annual accounts done by us and the tax return elsewhere pays twice for the same familiarisation and risks discrepancies.
A short message to info@onaccounting.ch is enough. We tell you what we need. You then receive a quote for your case, with a timetable, before we start work. If it suits you, we get going; if it does not, it has cost you nothing.
The initial meeting
The initial meeting is free and without obligation. Together we look at where your business loses time today and which of that work we can take on. Afterwards, you know where you stand.
Who would you like to talk to?
30 minutes, without obligation, by video or at our office in Dübendorf. Both of them hold the initial meeting personally.

Questions and answers
The complete accounts for the financial year, bank statements as at the balance sheet date, open receivables and payables, payroll data and contracts that extend beyond the end of the year. If we keep the ongoing accounts, we already have most of it.
That depends on the state of the accounts. With properly kept books and complete documents, the annual accounts are done within a few weeks. In our experience, missing receipts are the most common reason for delays.
The annual accounts are the annual financial statements under commercial law in accordance with the Swiss Code of Obligations: balance sheet, income statement and notes. The tax return derives the taxable values from them. The two are connected, which is why we do them in coordination.
Yes, that is actually common. We check your entries, correct them where necessary and carry out the closing work. If we find larger gaps, we get in touch before this leads to additional work.
No. You grant us accountant access to your bexio, which takes two clicks. We post the closing entries directly there, so that nothing has to be copied back and forth. If your accounts run in a different system, it works just as well; we then work with your exports.
Small companies can opt out of the limited audit (eingeschränkte Revision) if all shareholders agree and there are no more than ten full-time positions. Since 2025, the waiver only applies to future financial years. Our audit requirement check (in German) shows in five questions at most whether this is possible for you, and we are happy to clarify it with you. If we prepare your annual accounts or keep your books, we do not audit them ourselves but refer you to an independent auditor (Revisionsstelle).
Yes, for GmbH and AG. We prepare both in coordination, so that the annual accounts and the tax return match and the tax administration has no reason for queries.
Because before the first look, we do not know what state the accounts are in. A properly kept year is closed quickly; a patchy one costs many times as much in corrections. We therefore take a look first and then make you an offer, before the work begins, so that you can decide in peace. If we keep your accounts ourselves throughout the year, the annual accounts are included in the subscription and cost nothing extra.
The earlier, the more relaxed. Bank statements as at the balance sheet date, open items and the payroll data are the most important parts. We set out the exact timetable in the quote.
A comparison is only worthwhile if you compare the same scope. Our starting price is CHF 2,950, and it includes four parts: the tax return of the legal entity, the draft minutes of the general meeting, the VAT turnover reconciliation required by law and a review of your bexio settings. When comparing quotes, it is therefore best to ask first whether the tax return is included. And if we keep the accounts throughout the year, the annual accounts are included in the subscription and cost nothing extra.
That depends on turnover. Up to CHF 500,000, a statement of income, expenditure and financial position is sufficient, colloquially known as the Milchbüechlirechnung. Above this threshold, the same applies as for a GmbH: double-entry bookkeeping and annual financial statements under the Swiss Code of Obligations. What counts is the turnover of the last financial year, which is why the change often comes after a good year and catches people by surprise. For the tax return, you need clean figures in both cases.
With the general meeting, nothing dramatic happens at first. It has to be held late, and the board of directors (Verwaltungsrat) is responsible for this. It becomes more serious with taxes: if you do not file the tax return, you will be assessed at the authority’s discretion, and this assessment is almost never in your favour. An extension is possible and unproblematic there, as long as it is requested in time. With VAT, an extension is only available for filing the return, not for payment: the tax must be paid within 60 days of the end of the reporting period, and from day 61 default interest runs without a reminder (Art. 86 and 87 of the VAT Act, MWSTG). We submit the extension requests for you.
