Do you have an idea, a skill or a small project and finally want to turn it into your own thing, without drowning in bureaucracy from day one? For many people, this is exactly the point where the path into self-employment begins, and quite often it runs through a status with a slightly clunky name: Kleinunternehmer, the German small business owner. Sounds complicated. It really is not. Anyone who wants to become self-employed and starts with a modest turnover very often picks this route at the point of founding, because it works with little effort, no start-up capital and without the full VAT.
Even so, the term leaves almost everyone with question marks. What exactly is behind it? Where are the limits, and what really matters with taxes and invoices if you do not want to walk into an expensive trap? This guide takes you through it step by step and answers, in order, the questions that come up at the start. By the end you will know not only what a Kleinunternehmer is, but also how you become one yourself and how your finances run smoothly from the beginning.
The key points at a glance:
- A Kleinunternehmer is self-employed and uses the small business rule under Section 19 of the German VAT Act (§ 19 UStG). No VAT appears on their invoices.
- The rule applies as long as your turnover stays below €25,000 in the previous year and €100,000 in the current year.
- Anyone can be a Kleinunternehmer: traders (Gewerbetreibende) just as much as freelancers (Freiberufler). It is only about VAT, not about the legal form.
- The effort stays small. Instead of a monthly VAT return, a simple statement of income and expenses is usually enough.
- You still pay income tax on your profit, and in return you cannot reclaim the VAT contained in your purchases.
What is a Kleinunternehmer? Definition and legal basis
Put simply. A Kleinunternehmer is a self-employed person with little turnover who is therefore allowed to use a simplified tax rule and save a large chunk of the usual paperwork. The state wants to relieve founders and small businesses, and that is exactly why, in this status, you charge no VAT to your customers and pass none of it on to the tax office. A good deal. It does, however, come with a few clear conditions.
One misunderstanding is worth clearing up right away. In everyday language many people simply mean a small operation when they say small business, yet for tax purposes the term is defined much more narrowly. The Kleinunternehmer is precisely defined, namely through the level of turnover and the rule under Section 19 of the VAT Act. Whether you work full-time or part-time, by the way, makes no difference to this classification.
The small business rule under Section 19 UStG
So what does Kleinunternehmer actually mean for your tax, without the marketing gloss? At the centre sits the small business rule under § 19 UStG, which takes one of the most tedious duties of business life completely off your plate: you have to neither show VAT on your invoices nor pay it regularly to the tax office. Since 2025, two limits apply. In the previous year your turnover may be no more than €25,000, in the current year €100,000.
Stay below those figures and you save yourself a lot of admin, because the monthly return to the tax office falls away and your invoices stay pleasantly lean. There is a catch. The input VAT, meaning the tax contained in your own purchases, is something you cannot reclaim, which pure service providers barely notice but which quickly becomes a real cost factor for purchase-heavy businesses with expensive equipment. Better to run this point through calmly once.
The difference between Kleinunternehmer and Kleingewerbe
Few pairs of terms get mixed up as often as Kleinunternehmer and Kleingewerbe, even though they mean something completely different. The Kleingewerbe describes the legal size of your business, which runs without an entry in the commercial register, whereas Kleinunternehmer refers solely to VAT. A small business is sometimes a trade. Sometimes it is not.
In practice the two often go together, without being the same thing. You can run a Kleingewerbe and use the small business rule at the same time, and equally a freelancer becomes a Kleinunternehmer without registering any trade at all. The table below sums up the difference:
| Feature | Kleinunternehmer | Kleingewerbe |
|---|---|---|
| What it governs | VAT (§ 19 UStG) | Legal size and form of the business |
| Basis | VAT Act | Trade regulation and commercial code |
| Applies to | Traders and freelancers | Commercial activities only |
| VAT | Not charged | In principle possible |
| Limit | €25,000 previous year / €100,000 current year | No fixed turnover limit |
Advantages and disadvantages of the small business rule
Is the rule always the best choice? For most founders the advantages clearly win out at the start, yet there are situations in which standard taxation pays off noticeably more in the end. So an honest look at both sides is worth it before you commit.
The biggest plus is called simplicity. The monthly return falls away, your invoices stay lean, and to private customers you often look cheaper, because without added VAT your final price is simply lower and that gives you a noticeable edge over the competition, especially in the early days. That is a real argument.
The other side is something you still should not ignore. The tax on your purchases stays with you and gets genuinely expensive on big investments, and your § 19 UStG note tells every business customer, quite incidentally, that your turnover is still modest. Anyone who works a lot with companies sometimes looks a touch more professional under standard taxation. Here is the balance in short:
| Advantages | Disadvantages |
|---|---|
| No VAT on invoices | No input VAT deduction on purchases |
| No monthly return to the tax office | Less attractive to business customers |
| Lower prices for private customers | Turnover stays capped by the limits |
| Less bookkeeping and effort | Switching to standard taxation ties you in for five years |
How to become a Kleinunternehmer: the practical guide
And how do you become a Kleinunternehmer in practice? The path is shorter than most people fear, because in essence you register your activity, tick a box at the tax office in a single place and then get going. The following steps take you from the first registration to your first paid order. Not every point applies to every activity.
Become a Kleinunternehmer in 5 steps
Clarify right at the start whether you work as a trader or as a freelancer, because the whole rest of the process depends on it. Liberal professions such as doctors, lawyers, journalists or creatives do not register a trade, while everything else counts as a trade. This one classification decides which authority is responsible for you.
As a trader you register your business at the trade office (Gewerbeamt) of your town, which usually costs between €20 and €60. As a freelancer you skip this step entirely and turn to the responsible office directly.
After registering, the tax office sends you a questionnaire that you fill in conveniently via the ELSTER portal, and it is right here that you choose the rule under § 19 UStG. Shortly afterwards you receive your tax number and may officially write invoices.
Separate your business payments from your private account from the very start, because it makes every later tax return and every query enormously easier. With a Vivid business account you set money aside for tax through sub-accounts and keep every transaction in view in real time.
Finally, sort out your insurance cover and your health insurance, and it is best to put a share of every single order aside for income tax straight away. Then your first tax return stays relaxed.
Trade registration and tax registration
How do you become a Kleinunternehmer if you run a classic trade? Right at the beginning stands the registration form at the trade office, into which you enter your activity, the legal form and the address, and for which you receive your trade licence in return. Freelancers do not need this step; for them the tax office is responsible from the outset.
The tax registration follows, and today it runs almost entirely digitally. The tax office automatically sends you the matching questionnaire, which you submit via ELSTER and in which you estimate your likely turnover and choose the small business rule, which means the tedious monthly return falls away completely from the start. At the end stands your tax number. The first invoice can go out.
Opening a business account
A dedicated business account is not a legal requirement for a Kleinunternehmer, but honestly one of the best decisions you can make early on. Private and business payments stay cleanly separated from the start, which saves you hours of searching at year end and gives the tax office a clear, traceable picture in a possible audit. A business account for small companies keeps your bookkeeping in order from day one.
What should you look for when choosing? Above all, low costs and a few functions that take real work off your hands rather than just looking nice. With sub-accounts you set your tax money aside automatically, and with a card for business spending, invoicing and an export for your tax return you save yourself many small tasks week after week. That way the account becomes the calm centre of your finances.
A business account for small business owners
Separate private and business finances from the very start. With the Vivid business account, you set tax reserves aside in sub-accounts, write invoices and keep every transaction in view in real time.

What to watch out for as a Kleinunternehmer: finances and taxes
Once your business is up and running, the most important questions revolve around three things: taxes, bookkeeping and reserves. VAT falls away, true, but the income tax on your profit stays, and that is exactly why you are better off recording your income and expenses cleanly and completely from the first invoice on. It sounds like work, but it quickly turns into routine.
And the good news follows straight away. You need no double-entry bookkeeping and no elaborate balance sheet, because a simple statement in which you set your income against your expenses is enough, the so-called cash-basis accounting (Einnahmenüberschussrechnung, EÜR). Every business expense, from the laptop to office supplies, lowers your profit and with it your tax. You usually keep receipts for ten years.
One tip saves the most nerves. Move a fixed share of every profit to a separate sub-account straight away, then a later tax bill is long since planned for and does not hit you like a cold shower mid-quarter. Anyone who checks their numbers once a month handles the topic of taxes for the self-employed noticeably more calmly. For tricky questions, a tax adviser helps.
Writing invoices as a Kleinunternehmer
Even as a Kleinunternehmer, the usual mandatory details apply when writing an invoice, the ones every correct invoice has to contain. These are your name and address, those of your customer, the date, a sequential number, the service and the amount. Only one thing falls away completely: VAT.
In its place you add one short, unambiguous sentence, for example: "In accordance with § 19 UStG, no VAT is charged." If this note is missing, you quickly run into queries and trouble with the tax office that you could easily have spared yourself. Since 2025 you should also be able to receive electronic invoices, because between businesses the e-invoice is gradually becoming mandatory.
Kleinunternehmer or sole proprietor: legal forms and combinations
Two terms cause particular confusion at this point: sole proprietor (Einzelunternehmer) and Kleinunternehmer. The sole proprietor describes a legal form, that is the question of how your business is structured and who is liable for it, whereas Kleinunternehmer refers solely to VAT. Anyone who keeps small business and sole proprietorship cleanly apart finds the rest a good deal easier.
In reality the two almost always come as a pair. Most people who start as a sole proprietor use the small business rule in the first years, so you can easily be both at once. If your turnover climbs above the limits at some point, your legal form stays unchanged and only the tax rule switches to standard taxation, meaning normal taxation with VAT. You can go deeper in our guide on setting up a sole proprietorship.
Insurance for small business owners
With self-employment, the responsibility for your own cover moves into your hands. At the very top stands health insurance, because it is compulsory for absolutely everyone. If you start on the side, you usually stay comfortably insured through your main job, whereas as a full-timer you choose between statutory and private insurance and your contribution then depends on your income.
Depending on your activity, further policies make sense, without you having to take out everything at once. Professional or public liability insurance catches expensive damage claims, and anyone who works with costly equipment sensibly thinks about insurance for their own kit. Check your needs early and take out only what really fits your business. Good cover need not be expensive.
Digital tools and banking for small business owners
As a Kleinunternehmer you would rather put your time into the actual business than into endless paperwork. That is exactly why a digital setup pays off in the very first weeks, because a lean invoicing tool, a tidy cloud folder for receipts and a suitable business account together take the biggest part of the daily routine off your hands. Many of these tools now connect directly with one another.
The heart of your setup is the account. A Vivid business account brings payments, cards and bookkeeping together in a single place, so that you set your tax money aside through sub-accounts, catch every transaction instantly thanks to real-time notifications, and export your turnover for the tax return in a few clicks. Anyone who works alone wins back valuable time every week that way.
Avoiding common mistakes
Most mistakes come not from carelessness but simply from a lack of knowledge, and once you know them, you avoid them almost by yourself afterwards. These stumbling blocks come up especially often with small business owners:
FAQ: frequently asked questions
Frequently asked questions (FAQ)
When are you a Kleinunternehmer?
You are a Kleinunternehmer as soon as you work self-employed and use the rule under § 19 UStG. The decisive condition: your turnover was below €25,000 in the previous year and is expected to stay below €100,000 in the current year. The rule is chosen in the tax registration questionnaire at the tax office.
How much tax does a Kleinunternehmer pay?
You pay no VAT, because that is exactly what the rule frees you from. Income tax still applies to your profit as soon as it exceeds the basic tax-free allowance, and if you run a trade, trade tax (Gewerbesteuer) can be added. It only kicks in, though, above a tax-free amount of €24,500 per year, and only for sole proprietorships and partnerships.
Is a Kleinunternehmer an entrepreneur?
Yes, quite clearly. Under the VAT Act, a Kleinunternehmer is an entrepreneur who merely uses a special tax rule. So who counts? Any self-employed person who stays below the stated limits and has chosen the rule under § 19 UStG, whereby the rights and duties of an entrepreneur still apply in full.
What do Kleinunternehmer need to know about depreciation?
Even as a Kleinunternehmer you write off your purchases quite normally. Low-value items up to €800 net you deduct in full from your profit straight away, while more expensive purchases you spread over the years of their use. Because you do not reclaim VAT, you always calculate with the gross amount, that is including the tax you have already paid.
Conclusion: your start as a Kleinunternehmer
The path to becoming a Kleinunternehmer is one of the easiest routes into self-employment that German tax law has to offer at all. You register your activity, choose the rule under § 19 UStG and start with a minimum of bureaucracy. No VAT, no monthly return, just a simple statement of income and expenses, so your head stays clear for the actual business.
Keep an eye on your turnover limits, consistently set money aside for tax and separate your finances cleanly from the start, and then even the first tax return can do little to faze you. A suitable business account from Vivid takes a big part of that work off your hands. Nothing then stands in the way of your start as a small business owner.
