In short

Becoming self-employed means clarifying your activity, registering as Freiberufler or Gewerbetreibender, tax registration with the tax office, sorting insurance, and issuing compliant invoices. This guide walks you through ten steps with a timeline, costs, and common mistakes. It does not replace tax or legal advice.

Who is this guide for? Link to this section

You plan to work in Germany on a lasting basis and on your own account. You may be leaving employment or starting on the side. This text is for solo founders and very small teams without in-house advice on legal form. It covers Freiberuf and Gewerbe, not every special case such as pharmacies or financial services subject to BaFin.

Jupiter ERP supports contacts, invoices, and reports. Entry point: 14 days full features without a credit card. After that you can issue up to five invoices per month on Free. Quotes start on Basic. This guide explains the framework before and after that.

Timeline: the first twelve weeks Link to this section

Many founders underestimate the order of authorities. Trade registration and the tax office are not interchangeable. Insurers need a clear activity description. The table below is a grid. Adjust weeks to your industry.

PhaseWeeksOutcome
Planning1–4Offer, budget, Freiberuf/Gewerbe clarified
Registration5–6Trade or freelance start, ELSTER questionnaire
Finance7–8Tax number, business account, health insurance clarified
Go-live9–12Contracts, tool, first invoice

Step 1: sharpen business idea and offer Link to this section

Write in one paragraph which problem you solve and who pays. Without that clarity, registrations and prices stay vague. Test the offer in three conversations before you spend on website and hardware.

Check non-compete and side-job clauses in your employment contract. Becoming self-employed does not mean ignoring employer rules. Public funding or unemployment benefits can add reporting duties. Use official information, not only social media tips.

Build a simple revenue and cost forecast for twelve months. It does not need perfect Excel. A rough scale helps with small business choice and bank talks.

Define a minimum product you can deliver in under two weeks. Founders often fail on portfolios that are too broad. A clear entry service makes pricing, marketing, and first references easier.

Note three risks: personal liability, non-payment, illness. For each risk, a countermeasure: contract, deposit, reserves. That is planning, not scaremongering.

Step 2: decide Freiberufler or Gewerbe Link to this section

§ 18 EStG lists catalogue professions and similar activities. If you belong, you do not register a trade. Other commercial self-employed people go to the trade office. The line is not always clear. IT consulting without an engineering degree is often Gewerbe; technical planning with qualification is more often Freiberuf.

Crafts have their own rules in the HwO. Gastronomy needs Gewerbe and further permits. Read the cluster article and the decision tree download. If in doubt, the tax office decides in tax registration.

Many start as sole traders or Freiberufler. A UG or GmbH separates private and company assets more strongly but costs formation and ongoing compliance. For entry, sole proprietorship is often enough. Change later is possible but not free.

Speak with a tax advisor before you split company shares. This guide is not corporate law advice. Document agreements with co-founders in writing, even among friends.

Step 4: register Gewerbe or start as Freiberufler Link to this section

Gewerbetreibende complete trade registration with the municipality. Fees and processing time vary. After submission the office notifies tax office, IHK or chamber of crafts, and other bodies. Freiberufler skip this step and wait for the questionnaire from the tax office.

Choose a realistic start date. Backdated registration without good reason can trigger questions. Home office: check lease and local rules for home-based trade.

Step 5: tax registration questionnaire Link to this section

Via ELSTER you report activity, expected revenue, bank details, and whether you want small business status under § 19 UStG. Limits are 25,000 EUR prior-year revenue and 100,000 EUR in the current calendar year. References to 22,000 EUR are outdated.

You receive a tax number and often a VAT ID from the response. Without a number you should not invoice business customers. Use the worksheet download so all details match trade registration.

Step 6: small business or standard taxation Link to this section

Small businesses issue invoices without VAT and do not deduct input VAT. That simplifies paperwork but can leave expensive purchases at gross cost. Standard taxation often fits B2B customers and investments better.

You bind the choice in the questionnaire and in Jupiter ERP under taxation type. Mid-year switches are admin-heavy. Model the change with your advisor before you exceed the limit.

Step 8: health insurance and social insurance Link to this section

As self-employed you choose or stay in statutory health insurance or go private. Contributions depend on income, family status, and supplementary cover. Ask your fund for the expected amount in writing. Flat internet figures are often outdated.

Whether and when mandatory statutory pension insurance applies to self-employed people depends on the specific activity. Without a reliable primary source from the Federal Ministry of Labour and Social Affairs, do not claim blanket pension obligation. Clarify your situation with your fund, employers' liability insurance (BG), or advice.

Accident insurance via the BG matters for many activities. The BG often registers you automatically after trade registration. Read mail and contact them if unsure.

Continue reading

Step 9: contracts, privacy, and insurance Link to this section

Use template contracts for services, privacy, and website legal notice (Impressum). As controller under GDPR you document processing activities once you store personal customer data.

Business liability and professional liability where needed protect against damages. Need depends on industry and partners. Read policy terms, not only marketing pages.

Step 10: first invoice and ongoing routine Link to this section

In Jupiter ERP set up company, taxation type, number range, and first customer. Generate a PDF preview. Mandatory fields follow § 14 UStG or § 34a UStDV for small businesses.

E-invoicing: reception duties and issue deadlines are phased. Details are in the article on e-invoicing for founders, not in this guide. Jupiter ERP embeds ZUGFeRD in the PDF when the feature is active.

After 14 days trial without credit card you move to Free or a paid plan. Free: five documents per month, invoices only, ten contacts, one user. Test now whether the workflow fits you.

Side business: job and self-employment in parallel Link to this section

Many start beside employment. That eases cash flow but adds organisation. Clarify in writing whether your contract allows side work and whether customers or industries are excluded. A short note to the employer avoids conflict later if the contract requires it.

For tax, income from employment and self-employment add up in the income tax return. Allowances and progression can raise tax on your salary. Plan reserves for back payments. Trade tax can apply above an allowance even if the side business looks small.

You need fixed blocks for client work and admin. If you invoice in the evening, use the same care as on weekends. Jupiter ERP keeps number range and PDF consistent but does not replace time planning.

Plan funding and finance realistically Link to this section

Start-up advice from the IHK or founder centres is often free or subsidised. Use sessions for business plan feedback and registration paths. That does not replace individual tax planning but avoids wrong turns on forms.

KfW and state banks offer programmes with changing terms and guarantees. Read leaflets yourself before signing. Interest and repayment strain cash flow even when early months are low on payouts.

Equity and private savings reduce dependence on credit decisions. Model six to twelve months of fixed costs without revenue as a stress case, not pessimism. That helps you survive slow client acquisition.

Bookkeeping and record-keeping duties Link to this section

Small sole traders often use cash-basis accounting (EÜR) when no balance sheet is required. Every income and expense needs a receipt and assignment. Cash books and mixing private/business are classic audit points.

GoBD requires traceable, complete, and immutable records generally from when you keep books digitally. Test exports and backups before the tax office asks. Jupiter ERP stores receipts and invoices centrally. DATEV export is on higher plans.

Clean books from day one save stress at the first audit. Everything on a private account costs hours to reconstruct later. Set folder or tool rules before the fifth customer pays.

IHK, chamber of crafts, and employers' liability insurance Link to this section

Gewerbetreibende are usually IHK-liable. Fees follow profit or revenue per bylaws. Freiberufler under § 18 EStG are often exempt. Mixed activities can trigger fees. The IHK offers training and network but is not the tax office.

Craft businesses fall under the chamber of crafts. Master craftsman trades need qualification or exceptions. Advertising craft work without registration risks fines.

The BG covers accident risks in the business. Mail often arrives automatically after trade registration. Report activities truthfully because hazard classes affect contributions.

A name should be easy to say, searchable, and free of third-party trademark rights. A quick EUIPO or DPMA search is cheaper than a warning letter. Register the domain separately from trade registration.

Every commercial website needs a complete Impressum under TMG and clear privacy information under GDPR once you use contact forms or tracking. Cookie banners alone are not enough if processing is not documented.

Email on your own domain looks more professional than freemail. SPF, DKIM, and DMARC reduce delivery issues for invoices. Jupiter ERP sends documents via configured channels. Check spam folders during testing.

Win first customers without false promises Link to this section

Network, former colleagues, and local events often bring first jobs. Platforms can be channels but read terms and fees. This guide does not mention third-party affiliate programmes.

Written quotes clarify service, price, and deadline. Jupiter ERP Free does not include quotes. Plan Basic if you need them. The 14-day trial shows full scope before you decide.

Deliver on time and document extra work. Price increases without a contract cause disputes. A clean invoice with correct mandatory fields supports payment discipline.

Steps 1 to 3 in detail: preparation Link to this section

Validate willingness to pay, not only interest. Three concrete replies with a price beat ten likes. Adjust the value proposition until at least one person would pay.

Legal form and liability depend on risk and partners. A high-damage profession favours insurance and clear contract clauses over rushed founding. Document shareholder agreements even in 50/50 friend start-ups.

Budget tax advice, insurance, software, and reserves before marketing spend. Printing flyers without a tax number means you cannot bill the job cleanly.

Steps 4 to 6 in detail: authorities and tax type Link to this section

Trade registration and freelance start must match real activity. Contradictions between trade office text and ELSTER questionnaire trigger follow-up. Use the same keywords.

In the tax registration questionnaire you estimate revenue and profit. Large deviations in year one are normal but should be explainable. Choose small business only with plausible limit compliance.

Standard taxation versus § 19 UStG affects pricing and investments. Do not switch monthly. Align tool settings and actual invoices.

Steps 7 to 10 in detail: cash flow and sending Link to this section

Separate business and private accounts strictly. Document transfers. Use cards only for business or input VAT and receipts get mixed.

Health insurance as self-employed: get an individual contribution calculation. Flat blog figures are often wrong. Statutory vs. private is a long-term choice.

First invoice: read the PDF like a customer. Tax number, service description, payment term, small business note if applicable. Then send and assign payment.

Read e-invoicing duties in the knowledge article for founders. This guide links instead of duplicating deadlines that can change by law.

Typical costs in the first year Link to this section

Costs vary strongly by industry and region. The table gives orders of magnitude without guarantee. KfW loans can change terms. Check current programmes on the KfW website.

VAT pre-returns for new founders Link to this section

New founders generally must file monthly VAT pre-returns in the founding year and the following year. A transition period allowed quarterly filing under conditions. Whether that still applies or monthly duty returns from 2027 depends on current law. Enter deadlines only after you have checked the current text.

Small businesses without VAT liability often have fewer pre-returns. The tax office decides in the notice. Do not ignore ELSTER deadlines even with low revenue.

Pre-return is not the same as payment: you report VAT due for the period. Liability can fall with input VAT. Plan liquidity when large customers pay late but VAT is due.

Software can prepare totals; filing often runs via advisor or ELSTER. Store confirmation PDFs. Corrections use separate procedures. Get help instead of guessing.

Myths and common misinformation Link to this section

Myth: 22,000 EUR small business limit. Since the reform, 25,000 EUR in the prior year and 100,000 EUR in the current year apply. Citing old blog posts leads to wrong planning and wrong invoices.

Myth: automatic pension obligation for all self-employed people. Whether mandatory statutory pension insurance applies depends on the activity. Without a reliable BMAS source for your case, do not claim blanket obligation. Ask for advice.

Myth: trade registration is enough for tax. Without the tax registration questionnaire you usually get no tax number for invoices. Trade office and tax office are separate steps.

Myth: first invoice can wait until revenue arrives. Once you bill for deliverables you need correct details. Proforma and tests stay internal. Customer invoices without a number are risky.

Myth: private account always suffices. Tax office and GoBD expect traceable assignment. A business account is not always legally mandatory for every sole trader but is almost always practical.

Myth: e-invoicing only applies later for everyone. Deadlines are phased. Founders should read the knowledge article on e-invoicing instead of waiting by default.

Myth: Free includes quotes. Jupiter ERP Free is five invoices per month without quotes. Quotes start on Basic. The 14-day trial shows full scope before you choose.

Myth: health insurance always costs the same. Contributions are fund-specific. Get figures in writing before you cancel and switch.

Home office and mobile work Link to this section

If you work from home, check lease, house rules, and municipality. Not every flat allows quiet Gewerbe. Neighbours and noise become an issue if customers visit.

Separate workspace physically where possible. Tax home office allowance and business expenses are separate income tax topics. Document square metres and use with advice.

Equipment: ergonomic chair, backup internet, encrypted disk. Customer data on private devices without encryption is a GDPR risk.

If you work on the road you still need a fixed business address for Impressum and tax office. Mailbox services are allowed if they meet requirements. Clarify before printing business cards.

Ten mistakes that cost founders dearly Link to this section

First: invoices without tax number to businesses. Second: small business chosen despite high input VAT on investments. Third: private spend on the business account without assignment. Fourth: missing sequential invoice numbers despite customer requirements.

Fifth: trade registered only after months of revenue. Sixth: VAT limits planned with outdated 22,000 EUR figures. Seventh: no written agreement on side work beside employment. Eighth: customer data processed without privacy notice.

Ninth: e-invoicing duty ignored although customers expect structured data. Tenth: no backup of receipts and contracts. Jupiter ERP helps with receipts and invoices but does not replace advice or retention duty from cloud alone without export.

Work through the list before you click send. If something does not match, stop and ask your tax advisor.

  • Freiberuf or Gewerbe registered correctly
  • Tax registration questionnaire submitted
  • Tax number stored in Jupiter ERP
  • Taxation type small business or standard set
  • Number range active, no duplicate numbers
  • Contact with full address
  • Mandatory fields checked in PDF preview
  • Bank details correct
  • E-invoicing setting chosen deliberately
  • Payment term and dunning understood

The first year month by month Link to this section

Month 1: focus on clean registrations and ELSTER. No heavy marketing campaign while the tax number is missing. Set up Jupiter ERP and write an internal test invoice.

Month 2: first real customer invoices, assign payments, collect receipts. Check whether small business or standard taxation fits reality. Talk to your advisor if revenue grows faster than planned.

Month 3: fix routines: weekly receipt scan, monthly account review. Read tax office and IHK mail immediately. Note deadlines.

Month 4: tighten contracts when projects repeat. Adjust prices if you underestimated. Free only fits very few invoices. Plan Basic when you need quotes.

Month 5: investments only with receipt and clear business assignment. As small business you do not reclaim input VAT. As standard taxpayer check input VAT deduction.

Month 6: half-year review: revenue vs. questionnaire forecast. Inform tax office if needed when figures diverge. Plan holiday but keep ELSTER deadlines in the calendar.

Month 7: market only when you can deliver. New customers without capacity hurt reputation. Document working time for later price adjustments.

Month 8: review insurance: is liability still fit? Update equipment list. Privacy: deletion concept for old contact requests.

Month 9: involve tax advisor for year-end planning. Discuss advance payments and reserves. Dunning open receivables if the contract allows.

Month 10: inventory and depreciation if relevant. Book software licences as business expense. Test export from Jupiter ERP.

Month 11: prepare income tax: complete documents. Mark private shares. Time last investments in the year with advice.

Month 12: light year-end for EÜR: income, expenses, receipts. Thank customers without being pushy. Write goals for year two.

Working with tax advisors and ELSTER Link to this section

A firm can handle questionnaire, pre-returns, and annual return. You remain responsible for receipts and truthful data. Deliver structured monthly exports instead of shoeboxes.

ELSTER access belongs in your admin even if the firm files. Store passwords securely. Renew certificates in time.

Ask for a fixed founder package price and hourly rates for special cases. Compare two offers if you have time. Cheap is not always fast.

Jupiter ERP does not replace a firm but reduces media breaks for invoices and contacts. DATEV export from Business plan can ease handover if your firm uses DATEV.

The ten steps again in depth Link to this section

Step one remains the most common failure: too much product, too little paying demand. To become self-employed you need one sentence on why someone pays today. Test prices openly. Discounts without cost coverage are not a business model.

Step two splits Freiberuf and Gewerbe. The decision affects registration path and chamber. It does not automatically change tax progression. Read § 18 EStG alongside trade office guidance.

Step three protects private assets. Sole traders are fully liable. Customer and supplier contracts should limit liability where legally allowed. That is lawyer work, not a forum.

Step four is the visible start at the trade office or written begin as Freiberufler. Date and activity must match. Do not ignore authority mail.

Step five is ELSTER. Small business choice and revenue forecast shape years. Corrections are possible but costly in time.

Step six decides input VAT and invoice layout. Do not switch lightly. Customers notice price changes.

Step seven separates money flows. Without account separation EÜR becomes a puzzle. Banking apps do not replace bookkeeping.

Step eight is social insurance. Health insurance is mandatory thinking; pension insurance is case by case. Do not forget accident cover via BG.

Step nine is contracts and insurance. A project without written scope ends in dispute. Privacy is duty, not optional.

Step ten is the first invoice. Mandatory fields, ZUGFeRD if active, payment term. Jupiter ERP: 14 days trial, then Free or paid plan.

Jupiter ERP in everyday founding Link to this section

You need a system that bundles invoices, contacts, and later receipts. Jupiter ERP starts with guided steps for company and documents. The trial shows quotes, reports, and e-invoicing even if you later use Free for invoices only.

Free means: five documents per month, no quotes, one user, ten contacts, 100 MB storage, 0 EUR if you book no plan. Quotes and more volume start on Basic. Do not auto-book after the trial.

After the trial decide whether you need invoices only or quotes too. Upgrade to Basic anytime when volume grows. Export and EÜR features sit on higher plans. Read the pricing page before booking.

Closing: your next three actions Link to this section

Action one: put in your calendar when you will clarify Freiberuf or Gewerbe and whom to ask. Without a date, start slips by months.

Action two: open the ELSTER questionnaire worksheet and fill master data, before trade registration if possible. Consistent text saves follow-up.

Action three: start the 14-day Jupiter ERP trial if you will invoice in the coming weeks. Set up company, taxation type, and a test contact. Read the first invoice article in parallel.

If you complete these three points you have implemented the guide, not only read it. Everything else is in cluster articles on trade, questionnaire, and small business.

Remember: becoming self-employed is not one event but a series of registrations, routines, and corrections. Plan buffer, not perfection on day one.

If you exceed small business limits in the current year, react early. Do not wait for year-end. Customers need correct invoices with or without VAT.

Document advice calls with date and core message. Tax advisor and IHK do not replace your own records when the tax office asks.

Use the monthly calendar download for VAT pre-returns and annual deadlines. Enter dates only after checking current law.

Compare software price and features objectively. Jupiter ERP Free covers small invoice volume. Growth needs matching plans.

Close this guide knowing orientation is not a substitute for advice. When unsure, always clarify your individual case.
