Small Business Regulation in Germany: Everything You Need to Know

When you start as a freelancer in Germany, you’ll sooner or later be confronted with the question: Should I use the Kleinunternehmerregelung or register for VAT? This decision shapes not only your invoicing but also your entire business activity. However, many self-employed professionals make this choice without understanding all the consequences.

The Kleinunternehmerregelung, regulated in §19 of the German VAT Act, is a special regulation designed to make it easier for small businesses to start self-employment. It allows you to be exempt from VAT obligations, which means you don’t need to show VAT on your invoices and don’t need to file regular VAT returns. Sounds tempting? It is – but only under certain conditions.

Understanding the Basics

Before we dive into the details, it’s important to understand what the Kleinunternehmerregelung actually is and why it exists. The German tax system recognizes that small businesses and freelancers often don’t have the resources to manage complex tax structures. The regulation was therefore introduced to reduce bureaucratic burden and make it easier to start self-employment.

The requirements are clearly defined: you can use the Kleinunternehmerregelung if your total revenue in the previous calendar year did not exceed 25,000 EUR (net) and your revenue in the current year does not exceed 100,000 EUR. These thresholds have applied since 1 January 2025; before that they were 22,000 EUR gross and a 50,000 EUR forecast.

In the year you start, there is no previous-year turnover. Only one limit applies then: your turnover in the year you start must not exceed 25,000 EUR, not 100,000 EUR (BMF letter of 18.03.2025, section 19.1(3) UStAE). If you take in more than 25,000 EUR in your first year, you become VAT-liable from the sale that crosses the limit.

It’s important to understand that this refers to revenue, not profit. All income from your self-employed activities counts, even if you have multiple side activities.

The Advantages in Detail

The most obvious advantage of the Kleinunternehmerregelung is simplicity. Imagine you create an invoice for 1,000 EUR. As a small business, that’s also the amount your customer pays – done. No calculations, no VAT, no confusion. For many freelancers who are just starting out, this clarity is worth its weight in gold.

But the advantages go beyond simplicity. If you work mainly with private customers, you can advertise with prices that are 19% lower than your VAT-registered competitors. A customer choosing between two providers will likely choose the cheaper one – and that’s you. This competitive advantage shouldn’t be underestimated, especially in markets where price plays an important role.

The bureaucratic relief is another major advantage. While VAT-registered businesses must file monthly or quarterly VAT returns, you as a small business can focus entirely on your business. No deadlines, no forms, no additional work. Since 2025, Kleinunternehmer usually don’t have to file an annual VAT return either, unless the tax office (Finanzamt) specifically asks for one.

One duty remains, though: like every business, you must be able to receive e-invoices since 2025. An email inbox is enough. As a Kleinunternehmer you don’t have to issue e-invoices yourself.

Don’t Overlook the Disadvantages

But as with most things in life, there’s a flip side. The most important disadvantage is that you cannot deduct input VAT. This means: Every VAT you pay on your business expenses cannot be reclaimed. If you buy software for 1,190 EUR (including 190 EUR VAT), you pay the full 1,190 EUR as a small business. A VAT-registered competitor would pay only 1,000 EUR net, since they can deduct the 190 EUR as input VAT.

This difference can add up quickly. If you regularly make larger purchases – whether new hardware, software licenses, or professional services – the lack of input VAT deduction can become more expensive than the bureaucratic relief is worth. It’s therefore worth doing a rough calculation before deciding: How high are your estimated VAT-liable expenses? The VAT on these is essentially the price you pay for simplicity.

Another aspect many don’t consider is perception among business customers. While private customers are happy about lower prices, many companies expect their suppliers to be VAT-registered. The reason is simple: Companies can deduct VAT as input VAT, so it’s irrelevant to them whether you show VAT or not. An invoice without VAT can still raise questions with some business customers. It has nothing to do with a missing VAT ID, by the way: Kleinunternehmer can apply for a VAT ID (USt-IdNr) from the Federal Central Tax Office too, for example for business with companies in other EU countries.

When Is the Kleinunternehmerregelung the Right Choice?

The answer depends heavily on your individual situation. If you’re just starting out, still uncertain about your long-term revenue, and work mainly with private customers, the Kleinunternehmerregelung is often the best choice. It gives you the opportunity to focus on your business without having to worry about complex tax matters.

It’s particularly advantageous if you mainly offer services and have few VAT-liable expenses. A consultant who mainly works from home and only needs a laptop and internet connection benefits significantly more from the regulation than someone who regularly buys expensive equipment or materials.

The regulation is also ideal if you value simplicity. Invoicing becomes significantly simpler, and you don’t need to worry about VAT calculations. Still keep an eye on your turnover, so you notice in time when you’re getting close to the limits.

When Should You Switch to VAT Obligation?

There are clear signals that indicate a switch to VAT obligation might make sense. The most obvious case is when you exceed the revenue thresholds. From 25,001 EUR in the previous year you become VAT-liable the following year; if you exceed 100,000 EUR during the current year, the status ends immediately — the very transaction that takes you over is already taxable. In this case, it’s better to plan the switch proactively rather than being surprised.

But even if you’re still below the thresholds, a switch can make sense. If you work mainly with business customers, VAT obligation often makes more sense. Your customers can deduct VAT anyway, so the price difference is irrelevant to them. At the same time, you can deduct input VAT yourself, which reduces your expenses.

Another important factor is your business expenses. If you regularly make larger investments – whether in equipment, software, or professional services – input VAT deduction can quickly be worth more than the bureaucratic relief of the Kleinunternehmerregelung. A simple calculation helps: Estimate your annual VAT-liable expenses and multiply by 19%. The result is approximately the amount you could save through input VAT deduction.

Practical Implementation

If you decide to use the Kleinunternehmerregelung, you must indicate this to the tax office. This usually happens when filling out the tax registration questionnaire, which you receive when first registering as self-employed. In the VAT section, you can check that you want to use the Kleinunternehmerregelung.

On your invoices, you must then point out the exemption, for example with “No VAT charged under § 19 UStG” (§ 34a UStDV). This note belongs on every invoice. If you set up the Kleinunternehmer scheme in Solobooks, it appears on your invoices automatically.

Keeping an Eye on the Thresholds

One of the most common mistakes freelancers make is not keeping an eye on the revenue thresholds. It’s easy to get lost in daily work and forget that revenue is continuously rising. Suddenly you cross one of the thresholds — and with the 100,000 EUR current-year limit that applies from that very transaction, with no transition period.

This can lead to problems, especially if you’re not prepared. You then suddenly need to show VAT on all future invoices, update your invoice templates, and possibly inform customers about the change. A better strategy is to regularly monitor your revenue and plan early when you approach the thresholds.

A simple routine: once a month, look at the total payments you’ve received this year. What counts is the payments received (§ 19(2) UStG). In Solobooks you see your income on the dashboard. Our rule of thumb, not a legal limit: from around 80,000 EUR this year, or 20,000 EUR in the year you start, prepare the switch in earnest. What to do then is in our guide to switching to regular VAT.

Making the Decision

At the end of the day, the decision for or against the Kleinunternehmerregelung is an individual weighing. There’s no universally right answer that applies to all freelancers. Instead, you must analyze your own situation: How high are your expected revenues? How many VAT-liable expenses do you have? Do you work mainly with private or business customers? How important is simplicity to you versus tax optimization?

If you’re uncertain, it can be helpful to consult a tax advisor. A brief consultation can help you understand the advantages and disadvantages for your specific situation. But even without a tax advisor, you can make an informed decision if you understand the basics and are honest with yourself about your needs and priorities.

A Look into the Future

The Kleinunternehmerregelung is not forever. Many successful freelancers start as small businesses and later switch to VAT obligation when their business grows. That’s completely normal and expected. The regulation is intended as a starting aid, not as a permanent solution for everyone.

If you decide to use the Kleinunternehmerregelung, you should consider this as a conscious choice for this phase of your business. Keep an eye on your development, and be ready to switch to VAT obligation when it makes sense. With the right tools and a good understanding of the rules, you can make these transitions smoothly.

For this trade-off you need two figures: your turnover and the VAT contained in your expenses. If you record your expenses with their VAT rate as you go, you always have both to hand.

Frequently Asked Questions Answered

Many freelancers wonder if they can switch back and forth. It depends on why you became VAT-liable. If you voluntarily opt out of the Kleinunternehmerregelung, you’re bound for at least five calendar years (§ 19(3) UStG). You can declare the opt-out up to the end of February of the year after next. If instead you became VAT-liable because you crossed a limit, there’s no lock-in: as soon as your turnover is back under both limits, the Kleinunternehmerregelung applies again automatically.

Another common question concerns side income. Do these count toward revenue? The answer is yes – all income from self-employed activities is added together. So if you have multiple freelance activities, you must add them all together to see if you’re staying within the thresholds.

What happens if you exceed the thresholds? It depends which one. If you exceed 25,000 EUR in the previous year, you become VAT-liable from 1 January of the following year. If you exceed 100,000 EUR during the current year, the status ends immediately — the very transaction that takes you over is taxable in full. From that point the normal filing duties apply, including VAT advance returns. The invoices you issued before that remain valid – there’s no retroactive VAT obligation.

The Right Choice for Your Business

The Kleinunternehmerregelung is a powerful tool for freelancers who are just starting out or are still small. It significantly simplifies accounting and gives you the opportunity to focus on what really matters: building your business and winning customers.

But as with all tax decisions, there’s no one-size-fits-all solution. What’s perfect for one freelancer can be disadvantageous for another. The art lies in honestly assessing your own situation and making the decision that makes the most sense for you and your business.

With the right tools and a good understanding of the rules, you can make this decision with confidence. Modern accounting software like Solobooks can help you keep track, understand your finances, and make informed decisions – whether you use the Kleinunternehmerregelung or are VAT-registered.
