Chart of Accounts for Swiss SMEs: A Practical Guide

The most popular advice about the chart of accounts for Swiss SMEs is simply wrong: anyone who believes every Swiss business must adopt a fixed schema is confusing order with obligation. The Swiss Code of Obligations requires a complete, accurate, and systematic recording of business transactions, but it does not prescribe a rigid account structure. This is precisely why the chart of accounts is primarily a standardization and comparison tool in practice — and those who use it properly save themselves a great deal of trouble with banks, auditors, and tax authorities.

A wild assortment of self-invented account numbers never looks creative in accounting — it just looks expensive. Banks, tax authorities, and auditors want to read reports structured according to a common logic, otherwise every inquiry becomes a tedious translation exercise. Anyone who also needs a clear management reporting summary quickly understands why clean accounts are not a luxury but the foundation for comprehensible numbers.

Why the Chart of Accounts Is Not Mandatory in Switzerland but Still Matters

The Swiss Code of Obligations (OR Art. 957) requires every business owner to keep books in a way that the economic situation of the company can be determined at any time. However, the law does not specify what the accounts should be called or numbered. This freedom is both an opportunity and a risk.

Why Practice Still Expects a Standardized Framework

Auditors, banks, and tax authorities work with standard reports. Anyone using an accepted chart of accounts like the Swiss SME chart of accounts delivers figures that are immediately understandable. This speeds up loan negotiations, simplifies tax returns, and reduces accounting costs.

What This Means for Self-Employed Individuals

For sole proprietors and freelancers: those who build a simple, clean account structure have their accounting under control — whether with accounting software or in Excel. The SME chart of accounts from the Swiss fiduciary chamber provides an excellent template that can be used leanly or comprehensively.

Chart of Accounts vs. Chart of Accounts Plan and Account Class Structure

The chart of accounts framework (Kontenrahmen) is the template — the systematic classification of all possible accounts by class. The account plan (Kontenplan) is what an individual business makes of it: the specific accounts it actually needs.

How the Numbering Logic Works

Account classes follow a consistent logic: 1 = fixed assets, 2 = current assets, 3 = liabilities, 4 = equity, 5 = revenue, 6 = expenses, 7 = closing entries. Sub-accounts can be freely created within each class.

The Most Important Classes in Practice

For an SME, classes 1 through 6 are often sufficient. Class 7 (closing entries) is generated automatically by accounting software.

The Swiss SME Chart of Accounts with Example Account Numbers

A practical chart of accounts for a Swiss SME includes the following accounts:

Accounts Found in Almost Every Business

• 1000 Machinery & Equipment
• 1500 Office Furnishings
• 2000 Inventory
• 1100 Bank
• 2000 Creditors
• 3000 Equity
• 5000 Service Revenue
• 6000 Material Expenses
• 6100 Personnel Expenses
• 6500 Rent Expenses

Cleanly Separating Revenue and Expenses

The separation between revenue (class 5) and expenses (class 6) is the most important basic rule. Anyone who creates an account like "Miscellaneous" where everything flows in loses all evaluation capability.

Correctly Assigning Income and Expenses with Booking Examples

Booking a Web Design Fee from Abroad Correctly

A web design fee from abroad is booked to account 5000 Service Revenue. The foreign invoice does not contain Swiss VAT but may include a reverse charge arrangement. Correct assignment to a clean revenue account is important for properly recording VAT obligations.

Expenses You Should Not Hide in Collective Accounts

Collective accounts are accounts you use only because you didn't make an effort. "Miscellaneous expenses" is one such account. Every expense that can be clearly assigned should be: rent, advertising, travel costs, software subscriptions, etc.

Properly Mapping VAT Accounts: Effective and Flat-Rate Methods

Swiss VAT accounting recognizes two methods: the effective method and the flat-rate method (Saldosteuersatz). Both require different accounts in the chart of accounts.

Effective Method and Relevant Accounts

With the effective method, VAT on revenue and input tax on expenses are booked separately. Relevant accounts:

• 5000 Service Revenue ( excl. VAT)
• 5001 VAT 8.1%
• 6000 Material Expenses (excl. VAT)
• 6010 Input Tax

Flat-Rate Method Without Separate Input Tax Accounts

With the flat-rate method, a flat rate is applied to total revenue. There is no separate input tax booking — only one account: 5010 Flat-Rate VAT.

Foreign Currencies and International Invoices in the Chart of Accounts

Anyone active abroad must book foreign currencies. A separate account 1101 Foreign Currency Bank or a foreign currency clearing account is suitable for this.

How the Foreign Currency Receipt Is Treated

The receipt is recorded in the original currency, and the amount is converted to CHF at the daily rate. The accounting system stores both amounts: the original amount and the CHF amount.

Exchange Rate Differences and VAT Considered Together

Exchange rate differences arising from conversion are either revenue or expenses. They have their own account number, e.g., 5500 Exchange Gain or 6500 Exchange Loss. VAT on the original amount is reported separately.

Lean Account Plan for Freelancers vs. Comprehensive SME Chart of Accounts

When Lean Is Sufficient

Freelancers with few business transactions often only need classes 1 (fixed assets), 2 (current assets), 5 (revenue), and 6 (expenses). Accounting can be fully represented with 15–20 accounts.

When a Larger Chart of Accounts Makes Sense

Anyone who employs staff, maintains an inventory, or has multiple business areas needs more accounts. Here, a more comprehensive SME chart of accounts with additional classes and sub-accounts is worthwhile.
