Starting a business, tax office, and bureaucracy
From classification as a commercial business or freelance profession through tax registration to invoices, receipts, and a reliable office routine.

Self-employment does not begin with the first invoice. Anyone starting a business in Germany should clarify early on whether the activity is commercial or freelance, how registration works, what information the tax office requires, and how invoices, receipts, and payments must be documented. A well-organized office prevents later queries, deadline problems, and unnecessary rework.
Many founders underestimate the administrative side of self-employment. Customers, prices, and services matter, but without reliable processes, problems quickly arise: missing receipts, incorrect invoices, unresolved payments, missed deadlines, or incomplete information for the tax adviser. A fixed start-up process is the better approach. First clarify the activity and legal form, then complete registration and tax registration, and afterwards organize invoicing, document filing, payment reconciliation, and deadlines properly.
Working on a self-employed basis means offering services or products on your own account and at your own risk. Unlike an employee, you are not integrated into another organization; you decide for yourself about customers, quotes, prices, working methods, and responsibility. At the same time, you also bear the obligations: registration, tax returns, invoices, document filing, payment monitoring, and communication with authorities or tax advisers.
Before registering, you must clarify whether your activity is classified as a commercial business or a freelance profession. Commercial operators register their activity with the trade office. Freelancers generally register their activity with the tax office and usually do not need a trade registration. The classification matters because obligations such as trade registration, trade tax, chamber membership, and start-up procedures may depend on it.
Once you start, you need to register for tax purposes. Commercial operators register their business with the competent authority. To obtain a tax number, the tax registration questionnaire is submitted electronically to the tax office through ELSTER. ELSTER specifies a deadline of one month after the activity begins. Without a tax number, many tax-related processes cannot be completed properly.
The small-business VAT scheme can make starting easier because VAT is not shown on invoices. New revenue thresholds have applied since 2025: total revenue in the previous year must not have exceeded €25,000, and the €100,000 threshold must not be exceeded in the current calendar year. For new founders, the €25,000 threshold is particularly relevant in the year the activity begins. Important: small businesses generally cannot deduct input VAT from incoming invoices.
An invoice is more than a request for payment. It is a document relevant for tax purposes. Invoices should therefore be complete, unambiguous, and traceable from the outset. Required details include the invoice number, invoice date, service, date or period of supply, customer details, amount, tax rate or reference to a tax exemption, and payment terms. Incorrect invoices often lead to questions from customers, tax advisers, or the tax office.
Since 2025, e-invoicing has generally been introduced for B2B transactions between domestic businesses. A simple PDF file is not considered an e-invoice because it is not a structured electronic format. Transitional rules apply to issuance for many businesses, but the ability to receive e-invoices should be available from the outset. New businesses should therefore think beyond PDF invoices and account for XRechnung, ZUGFeRD, and structured invoice data early on.
Everyday routines determine the quality of your administration. If documents are missing, payments are not matched, or deadlines are kept only in your head, bookkeeping becomes unnecessarily difficult. Proper filing means that every business transaction should remain understandable later: What was purchased or sold? When was it paid? Which document belongs to it? Are any questions still unresolved?
Many problems arise not because founders work badly, but because they establish their administration too late. Anyone who waits until year-end to sort documents, check invoices, or trace payments loses time and risks errors. A simple weekly and monthly routine is better. This keeps records complete, makes cooperation with the tax adviser easier, and helps you recognize sooner whether the business is financially viable.
Motorica does not replace tax advice and does not make business decisions for you. The software does, however, help you set up a well-organized digital office from the outset. Invoices, receipts, payments, tasks, and documents come together in one place. MIRA can analyze documents, explain terms, and make guidance easier to understand—including in the selected language.
FAQ
First clarify whether your activity is commercial or freelance. Depending on the case, the next steps are trade registration, tax registration through ELSTER, obtaining a tax number, setting up invoicing and document filing, and establishing a simple process for payments and deadlines.
No. Commercial activities must be registered. Freelance activities are generally reported to the tax office and usually do not require trade registration. The classification depends on the specific activity.
ELSTER specifies a deadline of one month after the activity begins for electronic submission of the tax registration questionnaire. The questionnaire is important so the tax office can register your activity and issue a tax number.
Not always. It can simplify the start because no VAT is shown. At the same time, input VAT generally cannot be deducted. Anyone planning major investments or working mainly with business customers should discuss the decision with a tax adviser beforehand.
E-invoicing has generally been introduced since 2025 for B2B transactions between domestic businesses. Transitional rules apply to issuance. However, the ability to receive and process structured e-invoices should be prepared from the outset.
Important records include outgoing invoices, incoming invoices, receipts, cash-register receipts, contracts, bank transactions, proof of payment, letters from public authorities, and tax-relevant emails. These records should be filed in an organized, searchable, and traceable manner.
No. Motorica helps organize and document invoices, receipts, payments, and deadlines. Tax advice, assessment of individual cases, and binding evaluations remain the responsibility of a tax adviser or the tax office.
