Why this matters
Many founders only look at what lands in their bank account. The EÜR forces you to think about income and expenses together. Only then does a clear picture emerge of whether your side business is actually making money.
Turn knowledge into a start plan
This guide explains one topic. Whether it is really a priority for you right now depends on your answers in the start plan.
Create start planWhat the EÜR Fundamentally Shows
The Einnahmen-Überschuss-Rechnung (income-surplus statement) compares business income against business expenses. The result is either a profit or a loss from your self-employed activity.
For many small sole traders and freelancers, this approach is significantly simpler than double-entry bookkeeping. Even so, it still requires clean records and traceable categorisation.
Whether the EÜR is the right method for your situation depends on your type of activity, legal structure, and scale. Capital companies such as a UG or GmbH work differently and require considerably more formal accounting.
Thinking About Income Correctly
Income is not just classic invoices. Shop payouts, marketplace revenues, platform payouts, affiliate income, tips, or digital product sales can all be relevant.
It is important not to mix up gross amounts, fees, payment provider deductions, and VAT (Umsatzsteuer) logic. Platforms in particular often do not simply pay out a clean invoice total.
For now, the key starting point is: Where does money come in, from whom, through which channel, and with what proof?
Categorising Expenses Correctly
Expenses can cover software, work equipment, goods, materials, shipping, advertising, fees, training, specialist literature, a share of workspace costs, or professional services. Whether something is tax-deductible depends on the individual case.
The practical point is: without a receipt and a clear connection to your side business, an expense will be difficult to justify later.
Separate private and business costs as early as possible. This reduces errors and saves time when filing your tax return or working with a tax adviser (Steuerberater).
Why the EÜR Should Not Be a Year-End Project
If you only start at the end of the year, receipts, categories, and memories are often missing. The EÜR then becomes a search operation rather than a clear overview.
A better approach is an ongoing mini-routine: record income and expenses monthly, check receipts, note open questions, and update your tax reserves.
This also lets you spot earlier whether your side business is genuinely profitable, or whether prices, costs, or sales need to be adjusted.
When You Should Look More Closely
If you charge VAT (Umsatzsteuer), have customers abroad, use platforms, combine several activities, plan major investments, or set up a company, the simple EÜR logic quickly becomes more complex.
In those cases, it makes sense not just to read a guide, but to involve the tax office (Finanzamt), official sources, or a tax adviser.
Freya can help you prepare the right questions and describe your business model clearly.
