How does VAT work?
Value-added tax (VAT), also known as sales tax, is a tax on sales and services. Businesses add it on top of the net price, and customers pay the gross amount including VAT. The collected tax is remitted to the tax office but can be reduced by Vorsteuer (reclaimable VAT — VAT you paid on your own purchases). Ultimately, the end consumer bears the tax, not the business.
There are two tax rates:
- 19% (standard rate)
- 7% (reduced rate, e.g. for books, food, etc.)
→ The legal basis for VAT is the Value Added Tax Act (UStG).
The Exception: Kleinunternehmerregelung (§19 UStG)
The Kleinunternehmerregelung (small business exemption) is a simplification for self-employed people with low revenues.
If your revenue in the previous year was below €25,001 and you don't expect more than €100,000 in revenue in the current year, you qualify under the Kleinunternehmerregelung (§19 UStG) and the VAT obligation is waived. You then issue invoices without VAT, don't need to file monthly or quarterly advance VAT returns, and consequently don't need to file a VAT annual return either [1].
However, under the Kleinunternehmerregelung you also cannot deduct input tax — meaning the VAT you pay on products and services you purchase is not deductible.
You can voluntarily waive the Kleinunternehmerregelung and switch to standard taxation — but this decision is binding for 5 years.
Is it worth it?
Yes, it's worth it if:
- you plan few investments/purchases, since no Vorsteuerabzug (VAT reclaim) is needed or possible
- your main customers are primarily private individuals who are not entitled to VAT reclaim themselves
- you want to minimize bureaucratic effort
No, it's probably not worth it if:
- you have many business customers who want to reclaim VAT — this is only possible if you show VAT on your invoices
- you plan high expenses including VAT → forgoing Vorsteuerabzug (VAT reclaim) makes it more expensive
Standard Taxation & Vorsteuerabzug (VAT Reclaim)
If you don't fall under the Kleinunternehmerregelung (§19 UStG) or choose to waive it, standard taxation applies. This means:
- You charge VAT on your services → usually 19% and in some cases 7%.
- You can reclaim Vorsteuer on your expenses — you subtract the VAT included in your incoming invoices from the tax you owe.
Advance VAT Return & annual Declaration
If you are subject to VAT, you must regularly report to your tax office how much VAT you have collected and remit it.
→ Detailed information can be found in our guide Advance VAT Return
Umsatzsteuervoranmeldung (UStVA)
Monthly or quarterly, you report the VAT to be remitted minus your input tax to the tax office. The deadline is the 10th day after the end of the reporting period.
Annual VAT Return
After the end of the calendar year, you file a final return that accounts for all advance returns.
→ The advance VAT return corresponds to the prepayment of VAT. This way, you don't have to make a single large tax payment at the end of the year.
Writing Invoices correctly
Your invoice must contain certain mandatory information to be legally valid and to allow the recipient to deduct input tax if applicable.
What must be included?
- Full name (or company name) and address of the service provider (you) and your customer
- Your tax number or VAT identification number (VAT ID)
- The issue date of the invoice
- A sequential invoice number
- The quantity and type of service or delivery
- The net amount, the applicable VAT rate (e.g. 19% or 7%) and the VAT amount in euros
- The date of service, if it differs from the invoice date
- Note on tax exemption (if tax-exempt!)
💡 Our tip: Use a template with fixed mandatory fields (e.g. invoice number, tax rate, net/gross). This helps you avoid errors and stay legally compliant.
⚠️ What if you use the Kleinunternehmerregelung?
You still need to issue an invoice, but without showing VAT. Instead, a reference to §19 UStG should be included.
Special Case: International Business
If you work internationally or with special types of services, additional VAT rules apply.
Deliveries abroad
- Exports of goods to non-EU countries are generally VAT-exempt in Germany.
- For services to businesses in other EU countries (B2B), no German VAT is shown, as the place of supply is in the recipient's country (Reverse-Charge-Verfahren (reverse charge)).
- You write on the invoice, e.g.: "Steuerschuldnerschaft des Leistungsempfängers — VAT liability transfers to the recipient (§ 13b UStG)" - Important: - You need the VAT ID of your customer (and your own) - You must report the revenue in the Zusammenfassende Meldung (EU cross-border sales report) to the tax office.
- For occasional and small services to private individuals abroad (B2C), the VAT obligation usually remains.
- Within the EU, from a revenue of €10,000/year, the OSS procedure applies and the tax must be remitted via the Federal Central Tax Office. - More information on the OSS procedure is available here: Federal Central Tax Office
Purchasing Services from abroad
If you purchase services from EU or non-EU countries, the reverse charge procedure can also apply — this time in reverse: You become the "tax debtor".
You must calculate the German VAT on the foreign service and simultaneously reclaim it as Vorsteuer (if you are entitled to Vorsteuerabzug).
→ No financial burden, but obligation to report in your advance VAT return!
- Example: You buy a Canva Pro subscription (based in Ireland). You calculate 19% VAT on the invoice yourself and report it in ELSTER. At the same time, you reclaim it as Vorsteuer.
Common Mistakes
- Wrong tax rate
- 7% or 19% mixed up, e.g. with mixed services
- VAT reported too late
- The advance VAT return must be filed by the 10th day of the following month. Late filing incurs surcharges
- Permanent extension of deadline forgotten
- If you apply for it, you get one extra month — but it must be renewed every year
- Vorsteuer reclaimed twice
- This happens, e.g., when incoming invoices are booked twice or wrong receipts are used → always check invoice date and number
- Missing note for special cases
- e.g. for reverse charge transactions
