German freelancer and sole trader tax intake (Freiberufler and Gewerbetreibende)

Scope

This is the intake and triage Guide for a self-employed individual who lives in Germany: a Freiberufler (§ 18 EStG) or a Gewerbetreibender (§ 15 EStG) running a sole business. It tells an assistant which questions to ask, which documents to collect, which answers change the route, and which specialist Guide takes over. It computes no tax.

• Primary year: calendar year 2026, the tax year in force on 25 September 2026. The returns for 2025 are being filed now; see "Filing and payment".
• Covered: full-year residents (a home or habitual abode in Germany, § 1(1) EStG: "Wohnsitz oder ihren gewöhnlichen Aufenthalt"), sole proprietors, cash-basis profit (EÜR), up to a small team.
• Not covered: non-residents and part-year residents, partnerships as the business itself, GmbH and UG, balance-sheet filers, farming and forestry, payroll. See "When to refuse or refer".
• Who decides. The tax office decides the classification and facts like a home office being the centre of all work. Record, test and flag; do not settle.
• Review. A Steuerberater should review the work before anything is filed.

Ask the client first

Ask in batches of two or three. Skip anything the documents already answer.

• Year and residency. Which tax year are we preparing? Did you live in Germany (a home or your habitual abode) for all of it?
• What you do. Describe the work, the training it rests on, and who pays you. Do you also sell goods, earn commissions, broker deals or resell bought-in work?
• Registration. When did you start? Did you register a trade (Gewerbeanmeldung) with the municipality, or only report to the tax office? Did you send the tax office the registration questionnaire (Fragebogen zur steuerlichen Erfassung), and do you have a tax number?
• Structure. Do you work alone, or share profits with a partner (GbR or other partnership)? Is there a GmbH or UG? Are you entered in the commercial register (Handelsregister)?
• Staff. Do you employ anyone? How many, and are they subject to social insurance or on a Minijob?
• VAT. What was your total turnover in 2025, and what is it so far in 2026? Do your invoices show VAT, or do they carry the small-business note? Have you ever waived the Kleinunternehmer rule? How much VAT did you pay for 2025, and do you file monthly or quarterly? Do you have a one-month extension (Dauerfristverlängerung)?
• Profit method. Do you file an EÜR or a balance sheet? Has the tax office ever sent a notice telling you to keep books?
• Prepayments. Have you received an income tax prepayment notice (Vorauszahlungsbescheid)? What did your last assessment (Steuerbescheid) show?
• Social insurance. Is your work teaching or coaching, nursing or child care, midwifery, art or publishing, or a craft entered in the Handwerksrolle? Do you work, on a lasting basis, essentially for one client? Are you in statutory or private health insurance? Are you insured through the Künstlersozialkasse?
• Other income. Salary, rent, investments, crypto, a share in a partnership, foreign income?
• Church tax. Do you belong to a religious community that levies church tax? Which federal state do you live in, and in which municipality is the business run?

The method, step by step

1. Fix the year and test residency. Full-year residents only (§ 1 EStG). Anyone else is referred.
2. Screen out what this Guide cannot handle (partnership as the business, corporation, balance sheet, more than five employees). Stop there; see "When to refuse or refer".
3. Classify the work: Freiberufler or Gewerbe. Compare what the client does with the list in § 18(1) no. 1 EStG and the definition of a trade in § 15(2) EStG. See "Freiberufler or Gewerbe" below.
4. Check the registration of a new business: reports and questionnaire within one month (§ 138 AO); see below.
5. Settle the VAT status before reading any invoice, because it decides whether every amount is recorded net or gross. Test both Kleinunternehmer limits of § 19 UStG. For a client in the normal scheme, set the return period from last year's VAT under § 18 UStG. Then hand VAT to germany-vat-return.
6. Confirm the profit method. EÜR under § 4(3) EStG unless there is a duty to keep books. A Gewerbetreibender can be brought into bookkeeping by a tax office notice under § 141 AO. Details go to germany-bookkeeping.
7. Collect the documents (list below) and read what they already answer.
8. Record the prepayments from the Vorauszahlungsbescheid against the four due dates in § 37(1) EStG. Route the schedule to de-estimated-tax.
9. Screen social insurance. Test the pension duty list of § 2 SGB VI and, for artists and publicists, the KSVG. Do not advise on contributions: refer to de-social-contributions and the pension or KSK authority.
10. Route other income (de-capital-gains, de-crypto-tax, de-rental-income), confirm the picture in one summary, list open points as flags, hand over, and diarise the deadlines in "Filing and payment".

Documents to collect

• Business bank statements for the whole year.
• Sales invoices issued and purchase invoices or receipts.
• The last income tax assessment (Steuerbescheid) and any prepayment notice (Vorauszahlungsbescheid).
• VAT advance returns filed for the year, and any letter on the return period or a Dauerfristverlängerung.
• Last year's Anlage EÜR and the asset schedule (Anlage AVEÜR).
• Health and care insurance annual statement (Beitragsbescheinigung).
• For a new business: the trade registration, the tax office's letter with the tax number, and a copy of the registration questionnaire.
• Any notice from the pension insurance (Deutsche Rentenversicherung) or the Künstlersozialkasse.
• Any tax office letter, including a notice to keep books.
• Receipts for equipment, vehicles and other assets bought in the year.

Freiberufler or Gewerbe (§ 18 vs § 15 EStG)

This is the first fork of every German intake.

• The § 18 list. Freelance work is self-employed scientific, artistic, literary, teaching or educational work ("wissenschaftliche, künstlerische, schriftstellerische, unterrichtende oder erzieherische Tätigkeit"), plus the self-employed work of the professions the statute names: Ärzte, Zahnärzte, Tierärzte, Rechtsanwälte, Notare, Patentanwälte, Vermessungsingenieure, Ingenieure, Architekten, Handelschemiker, Wirtschaftsprüfer, Steuerberater, beratende Volks- und Betriebswirte, vereidigte Buchprüfer, Steuerbevollmächtigte, Heilpraktiker, Dentisten, Krankengymnasten, Journalisten, Bildberichterstatter, Dolmetscher, Übersetzer, Lotsen "und ähnlicher Berufe" (§ 18(1) no. 1 EStG).
• What is not on the list. Software developers, IT consultants, web designers, marketing agencies and "consultants" in general are not named. Such a client is a Freiberufler only if the work is one of the five activity types or a profession similar to a named one. Do not tell the client either way: flag it.
• The trade definition. A self-employed, lasting activity with the aim of profit that takes part in general commerce is a Gewerbebetrieb unless it is farming, a liberal profession or other self-employed work (§ 15(2) EStG). The 2026 EÜR instructions say the same for line 8 of the form: freelance income exists only "wenn die Voraussetzungen des § 18" EStG are met (BMF, Anlage EÜR 2026).
• Staff. A Freiberufler may use trained staff only while leading the work and taking personal responsibility for it on the strength of their own expertise ("leitend und eigenverantwortlich", § 18(1) no. 1 sentence 3 EStG). Flag any client with staff doing the core work.
• Mixed activities. Ask about every side line: sales of goods, commissions, brokerage, resold print or other bought-in work. Where the freelance and commercial parts can be separated, keep separate records and report them separately (Anlage S and Anlage G). Where they cannot, the classification of the whole is at risk. Flag it for the Steuerberater.
• Who decides. The tax office. A first treatment as Freiberufler can be reversed later, typically after an audit, with trade tax for past years. A binding ruling (verbindliche Auskunft) can settle a real doubt.

What follows from the answer

	Freiberufler	Gewerbetreibender
Start reported to	the tax office (§ 138(1) AO)	the municipality, which informs the tax office
Trade tax	none	every Gewerbebetrieb run in Germany (§ 2(1) GewStG); allowance for sole traders
IHK membership	no, unless entered in the Handelsregister	yes, if assessed to trade tax and running a business establishment in the chamber's district (§ 2 IHKG)
Size-based bookkeeping duty (§ 141 AO)	never	only after a tax office notice
Routed to	de-einkommensteuer-freelancer	de-einkommensteuer-freelancer and de-trade-tax

• IHK fees. Members are those "sofern sie zur Gewerbesteuer veranlagt sind" (§ 2(1) IHKG). § 3(3) IHKG frees unregistered sole traders from fees while their trade income or profit is not more than EUR 5,200.
• Trade tax in detail. The trade income of a sole trader is reduced by an allowance of EUR 24,500 per year (§ 11(1) GewStG: "Freibetrag in Höhe von 24 500 Euro"). It is an allowance, not a cliff: only trade income above it is taxed. The trade income is rounded down to full EUR 100 before the allowance. The rate base (Steuermesszahl) is 3.5% ("beträgt 3,5 Prozent") and the municipality's multiplier (Hebesatz) decides the tax. Income tax is then reduced by up to four times the trade tax base amount (§ 35 EStG: "das Vierfache"), within a ceiling set in § 35 and never above the trade tax actually payable ("auf die tatsächlich zu zahlende Gewerbesteuer beschränkt"). A trade tax return, filed electronically (§ 14a GewStG), is due only if the year's trade income exceeded EUR 24,500 (§ 25(1) no. 1 GewStDV: "den Betrag von 24 500 Euro überstiegen hat") or the tax office asks (§ 149(1) AO). Route every computation to de-trade-tax.

Registration of a new business

• Report the start within one month. Opening a trade is reported to the municipality on the official form, and the municipality informs the tax office. Starting freelance work is reported to the tax office directly (§ 138(1) AO). The same applies to moving or closing the business.
• The registration questionnaire. Anyone who must report a start must also give the tax office further details relevant to tax, "nach amtlich vorgeschriebenem Datensatz über die amtlich bestimmte Schnittstelle", so electronically; paper only on application for hardship (§ 138(1b) AO). In practice this is the Fragebogen zur steuerlichen Erfassung sent through ELSTER. The deadline is the same month: "innerhalb eines Monats nach dem meldepflichtigen Ereignis" (§ 138(4) AO).
• What to check. Was the questionnaire sent, and on time? What did the client choose there for VAT (Kleinunternehmer or not) and for expected turnover and profit? If it was never sent, the client should send it now; flag the delay.

VAT status and return period

• Kleinunternehmer (§ 19 UStG). VAT is not charged if total turnover (Gesamtumsatz) did not exceed EUR 25,000 in the previous calendar year ("25 000 Euro nicht überschritten hat") and does not exceed EUR 100,000 in the current year ("100 000 Euro nicht überschreitet") (§ 19(1) UStG). Both tests must be met. A turnover exactly at a limit is still inside.
• Start-up year. For a business that starts during the year, the current-year limit is EUR 25,000 (2026 EÜR instructions, line 12: "darf der Gesamtumsatz im laufenden Kj. 25.000 € nicht überschreiten").
• Crossing a limit in the year. The sale that takes current-year turnover over the limit is already taxed: the EÜR instructions say the receipt "mit dem Sie die jeweilige Grenze im laufenden Kj. überschreiten, unterliegt der Regelbesteuerung". Earlier sales stay exempt. Route to germany-vat-return at once.
• Waiver. A Kleinunternehmer may opt into normal VAT by an irrevocable declaration up to the last day of February of the second year after the tax year; it binds for at least five calendar years (§ 19(3) UStG). Ask whether the client ever waived.
• Invoices. A Kleinunternehmer must not show VAT on an invoice. VAT shown without entitlement is owed anyway (§ 14c UStG). An invoice without VAT does not by itself prove Kleinunternehmer status: check the turnover. Reading § 19(2) with § 1(1) no. 1 UStG, services supplied abroad are left out of the turnover test; confirm with germany-vat-return.
• Returns for a Kleinunternehmer. As a rule no advance returns and no annual VAT return, but the tax office can still ask for one, and a Kleinunternehmer who owes VAT as the recipient of a service from abroad (reverse charge) or on EU acquisitions must file for those periods (§ 19(1) sentence 2 with § 18(4a) UStG). Route to germany-vat-return.
• Normal scheme: the return period (§ 18 UStG). The default period is the calendar quarter. It is the month if the VAT for the previous calendar year was more than EUR 9,000 ("mehr als 9 000 Euro"). The tax office may release a business from advance returns if last year's VAT was not more than EUR 2,000; the annual return is still due. The test is last year's VAT, not turnover.
• New businesses, tax periods 2021 to 2026. A business started in the current year uses the expected VAT for that year for the test above; a business that ran only part of the previous year scales that year's VAT up to a full year (§ 18(2) UStG). This relief is written for 2021 to 2026 only; for 2027 check whether it has been extended, because the basic rule is monthly returns in the year of start and the year after.
• Deadlines. Advance returns and payment are due by the tenth day after the period ends ("bis zum 10. Tag nach Ablauf"). A Dauerfristverlängerung adds one month; a monthly filer pays a special prepayment of one eleventh of last year's prepayments (§§ 46 and 47 UStDV).

Profit method: EÜR for Freiberufler

• EÜR. Anyone not obliged by law to keep books, and not keeping them by choice, may work out profit as receipts less expenses (§ 4(3) EStG: "nicht auf Grund gesetzlicher Vorschriften verpflichtet sind, Bücher zu führen"). A Freiberufler not entered as a merchant can use the EÜR at any size. The Anlage EÜR goes to the tax office electronically (§ 60(4) EStDV).
• Gewerbetreibende: § 141 AO. The tax-law duty to keep books can start for a commercial business with total turnover above EUR 800,000 in the calendar year, or trade profit above EUR 80,000 in the business year (§ 141(1) AO). Either test is enough. The duty does not start by itself: it begins with the business year after the tax office's notice (§ 141(2) AO). Freiberufler are not named in § 141.
• Merchants. A merchant entered in the Handelsregister, or one who files a balance sheet for any reason, is outside this Guide: refer, and use germany-bookkeeping for the § 238 and § 241a HGB tests.

Income tax prepayments

Prepayments are due on 10 March, 10 June, 10 September and 10 December (§ 37(1) EStG). They are set by notice, usually from the last assessment, and only if they come to at least EUR 400 a year and at least EUR 100 per due date (§ 37(5) EStG). A client with no notice has not missed a payment. The tax office may adjust them until the end of the fifteenth month after the tax year (§ 37(3) EStG). Route to de-estimated-tax.

Social insurance: screen and refer

• Pension duty for some self-employed people. § 2 SGB VI makes these self-employed people compulsorily insured in the statutory pension scheme, among others: teachers and educators, and carers in sick, maternity, infant or child care, in each case if they regularly employ no insured employee; midwives; artists and publicists under the KSVG; craftspeople entered in the Handwerksrolle; and anyone who regularly employs no insured employee and works "auf Dauer und im Wesentlichen nur für einen Auftraggeber". A Minijob employee does not count as an employee for these tests. If a duty may apply and no pension contributions appear on the bank statement, flag it and refer to de-social-contributions and the Deutsche Rentenversicherung.
• Artists and publicists: the Künstlersozialkasse. Self-employed artists and publicists are insured in pension, health and care insurance through the KSK if they work in the field for a living and not just temporarily, and employ no more than one employee in that work, with trainees and Minijobs not counted (§ 1 KSVG). Ask whether the client is registered with the KSK; if not and the test may be met, refer.
• Health insurance. Ask whether the client is in statutory (GKV) or private (PKV) health insurance and collect the annual statement. How much of it counts as basic cover for the income tax deduction (§ 10(1) no. 3 EStG) is worked out in de-einkommensteuer-freelancer; take the figure from the insurer's statement, never estimate it.

• 2025 versus 2026 commuting. From 1 January 2026 the EUR 0.38 rate applies from the first kilometre. For 2025 returns it applied only from the 21st kilometre (BMF, what changes in 2026).
• Computers and software. The Finance Ministry accepts a useful life of one year ("Nutzungsdauer von einem Jahr") for computer hardware and software, so the cost can be deducted in the year of purchase; the item is still listed in Anlage AVEÜR (2026 EÜR instructions).
• Church tax. Read the rate from the client's last assessment, unless the client moved state or joined or left a church since then. It is set by the religious communities and differs by federal state; do not assume it.

Boundaries and exceptions

Situation	Treatment	Source
2025 turnover exactly EUR 25,000, 2026 turnover not over EUR 100,000	Still a Kleinunternehmer: the limits must not be exceeded	§ 19 UStG
2026 turnover crosses EUR 100,000 in October	The crossing sale and every later sale carry VAT; earlier sales stay exempt	2026 EÜR instructions, line 12
2025 VAT exactly EUR 9,000	Quarterly returns in 2026: monthly needs more than the limit	§ 18(2) UStG
Kleinunternehmer buys a service from a business abroad	Owes the VAT as recipient and files for that period	§ 18(4a) UStG
Work not named in § 18, no trade registered	Record as stated, flag: the tax office decides and trade tax may follow for past years	§ 18 EStG, § 15(2) EStG
Trade income not more than EUR 24,500	No trade tax after the allowance; no trade tax return unless the tax office asks	§ 11 GewStG, § 25 GewStDV
Gewerbe with profit above EUR 80,000 but no tax office notice	No § 141 AO duty yet; it starts with the business year after a notice	§ 141(2) AO
Artist employs two people in the artistic work (not trainees or Minijobs)	Outside the KSK test	§ 1 KSVG
Self-employed with one main client and only a Minijob helper	Minijob does not count as an employee: the one-client pension test may be met	§ 2 SGB VI

Worked cases

1. The software developer (§ 11 GewStG). Lena writes software for three agencies, has no trade registration and calls herself Freiberuflerin. Software development is not on the § 18 list, so record "Freiberufler, as stated; not named in § 18(1) no. 1 EStG" and flag it. Explain the stakes without deciding: if the tax office treats the work as a Gewerbe, trade tax and IHK membership follow. With trade income of EUR 30,000, the Gewerbe route would give EUR 30,000 less EUR 24,500 = EUR 5,500, times 3.5% = a trade tax base amount of EUR 192.50; the income tax credit could be up to four times that, EUR 770, but never more than the trade tax actually payable. Route to de-trade-tax and de-einkommensteuer-freelancer.
2. The translator near the VAT limit (§ 19 UStG). Tom, an Übersetzer (named in § 18), had total turnover of EUR 25,000 in 2025 and expects EUR 60,000 in 2026. He did not exceed EUR 25,000 in 2025 and will not exceed EUR 100,000 in 2026, so he remains a Kleinunternehmer in 2026, with no VAT on invoices. His 2026 turnover is above EUR 25,000, so for 2027 he moves to normal VAT from 1 January 2027. Route to germany-vat-return to plan the switch.
3. The new coach. Aylin starts freelance business coaching on 15 October 2026. She reports the start to the tax office and sends the questionnaire within one month; 15 November 2026 is a Sunday, so the deadline moves to Monday 16 November 2026 (§ 108(3) AO). As a start-up she stays a Kleinunternehmer only while 2026 turnover does not exceed EUR 25,000. Coaching may fall under the teachers' pension duty in § 2 SGB VI if she employs no insured staff: flag and refer to de-social-contributions.
4. The quarterly filer (§ 18 UStG). Max, a Gewerbetreibender in the normal VAT scheme, paid EUR 9,000 of VAT for 2025. That is not more than EUR 9,000, so his 2026 periods are quarters. The third quarter return is due on 10 October 2026, a Saturday, so it moves to Monday 12 October 2026. With a Dauerfristverlängerung it would be due one month later. Route to germany-vat-return.
5. The late 2025 return. Sara prepares her own 2025 returns and has not filed. They were due on 31 July 2026. She should file now. If the 2025 income tax return is still not filed 14 months after the year end (end of February 2027), a late-filing surcharge must be set, unless an exception applies such as tax fixed at zero or not above the prepayments (§ 152(2) and (3) AO).

When to refuse or refer

Stop, say why, and name the adviser needed.

• Part-year residents and non-residents. Different rules on limited tax liability. Refer to a Steuerberater who handles non-resident returns.
• Partnership as the business (GbR, PartG, OHG, KG). It files a separate declaration of profit shares. A client who is a partner alongside their own sole business stays in scope with a flag: the share arrives in a separate determination notice.
• GmbH, UG or other corporation. Corporate tax and trade tax rules differ. Refer.
• Balance-sheet filers, including merchants in the Handelsregister and a Gewerbetreibender whose § 141 AO duty has already started. A notice received during the year being prepared takes effect only from the next business year, so that year stays in scope with a flag.
• More than five employees. This is this Guide's own scope line, not a legal threshold. Payroll at any size goes to de-payroll.
• An unsettled classification that matters: work not named in § 18, freelance and commercial work that cannot be separated, or staff doing work the client does not lead. Record, flag, and tell the client the tax office decides and that a Steuerberater or binding ruling can settle it.
• VAT beyond the basics: a Kleinunternehmer crossing a limit mid-year, reverse-charge purchases, goods sold across borders, distance sales and the one-stop shop. Route to germany-vat-return.
• Social insurance. Any possible pension duty, KSK membership or health insurance question: refer to de-social-contributions and to the Deutsche Rentenversicherung or the Künstlersozialkasse.
• Business run in another tax office's district. The business profit is then determined separately (§ 180(1) no. 2 b AO). Flag it.
• Electric or plug-in hybrid business cars, disputed car use, and whether a home office is the centre of all work where the client also works elsewhere. Record and flag for de-einkommensteuer-freelancer.
• Farming and forestry. Refer.

Filing and payment

Returns for tax year 2026 (the income tax return duty is set out in § 56 EStDV; in practice a self-employed client with a profit files every year)

Return	Who	Deadline
Income tax return with Anlage EÜR and Anlage S or G	every client in scope	31 July 2027, a Saturday, so Monday 2 August 2027; with a Steuerberater, 29 February 2028
Annual VAT return	normal-scheme clients, and Kleinunternehmer only where § 18(4a) UStG applies or the office asks	same as above
Trade tax return	Gewerbetreibende with trade income over EUR 24,500, or if asked (§ 25 GewStDV)	same as above
VAT advance returns	normal scheme	tenth day after each month or quarter, plus one month with a Dauerfristverlängerung
Income tax prepayments	where a notice sets them	10 March, 10 June, 10 September, 10 December

• The rule. Annual returns are due seven months after the end of the calendar year ("sieben Monate nach Ablauf des Kalenderjahres", § 149(2) AO). Where a tax adviser prepares them, the deadline is the last day of February of the second following year (§ 149(3) AO), but the office can call a return in earlier (§ 149(4) AO). A deadline falling on a Saturday, Sunday or public holiday moves to the next working day (§ 108(3) AO).
• Returns for 2025, being filed now. Self-prepared: due 31 July 2026, now past. With a Steuerberater: last day of February 2027; 28 February 2027 is a Sunday, so Monday 1 March 2027.
