Why this matters
Money sitting in your account can easily look like freely available cash. In reality, it may include VAT (Umsatzsteuer) owed to the tax office, income tax (Einkommensteuer), trade tax (Gewerbesteuer), repayments, operating costs, and back payments. Building reserves is therefore not a luxury — it is a basic protective habit.
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 planReserves Are Not an Extra — They Are Part of Starting Up
In a side business, income often arrives irregularly: a project here, a client order there, a shop sale, a marketplace payout. That is exactly why it is risky to treat incoming payments as personal spending money right away.
The first step is not a perfect tax calculation. The first step is a clean separation: What is revenue? What is profit? What needs to be set aside for ongoing costs? And what might be owed in tax later?
This page gives you a learning framework. It does not replace professional tax advice and does not calculate a binding reserve amount for your individual situation.
Revenue Is Not Profit
Revenue (Umsatz) is what you charge your customers or receive through platforms. Profit (Gewinn) only arises after business expenses have been deducted.
For income tax purposes, what generally counts is your profit, not your revenue. That said, revenue still matters — for example, for VAT questions, the small business exemption (Kleinunternehmerregelung), growth planning, and liquidity management.
Especially when selling through marketplaces, payment providers, or online shops, do not overlook fees, shipping, returns, purchasing costs, software, and advertising. Otherwise your business will look more profitable than it actually is.
Think of VAT Separately
If you are subject to standard VAT rules (regelbesteuert), the VAT shown on your invoices is not your money. It is collected on behalf of the tax office (Finanzamt) and must be passed on. In return, input VAT (Vorsteuer) from your incoming invoices may be deductible.
If you use the small business exemption (Kleinunternehmerregelung), you normally do not charge VAT and generally cannot claim input VAT deductions. This makes the reserve logic simpler, but it does not mean your business is entirely tax-free overall.
The right choice depends on your type of customers, planned investments, growth expectations, and any special circumstances. If EU services, platforms, or major purchases are involved, you should look into this more carefully.

Plan for Advance Payments and Back Payments
As your profits grow, advance payments (Vorauszahlungen) for income tax or other taxes may become relevant. This is not a flaw in the system — it is simply a prepayment toward expected tax liability.
The problem arises when you only notice at tax return time that the money is gone. The tax bill then feels like a surprise, even though it was always a built-in part of running a business.
A simple monthly routine helps: review your income, subtract costs, check outstanding invoices, update your reserves, and avoid withdrawing everything for personal use.
When You Should Not Try to Figure It Out Alone
As soon as VAT, large investments, cross-border transactions, platforms, multiple income streams, a UG or GmbH, or employees come into play, getting proper tax guidance becomes more important.
Even with a small start, an initial consultation can be worthwhile if you are unsure whether the small business exemption (Kleinunternehmerregelung) is right for you, or how to plan your reserves realistically.
Freya can help sort through your questions, explain key terms, and put together a preparation checklist for your consultation. Binding tax assessments are the responsibility of the tax office (Finanzamt) or a qualified tax advisor (Steuerberater).
