The marketplace already collects German VAT. Why would I register?
Since July 2021, platforms remit German VAT on many marketplace orders. Sellers read that and conclude the topic is closed. For anyone with stock in Germany, it is not.
If your goods sit in Germany: yes, registration stays mandatory.
The deemed-supplier rule (§ 3 (3a) UStG) makes the platform remit VAT on B2C orders placed through the marketplace by non-EU-established sellers. It does not touch the rest of your footprint: storing goods in Germany still makes you a taxable person, and you still file monthly returns covering stock movements, the tax-exempt deemed supplies to the platform, B2B sales, own-website sales and your input-VAT refunds.
The platforms know this. Under § 25e UStG they are liable for your unpaid VAT, which is why Seller Central and TikTok Shop demand a valid German USt-IdNr from sellers with German stock and suspend accounts without one. The collection rule changed who remits some of the tax. It did not change who must be registered.
What the platform's collection actually covers
On a deemed-supplier order the law splits one sale into two: you make a supply to the platform (exempt under § 4 Nr. 4c UStG, with your input-VAT deduction intact), and the platform makes the supply to the consumer and remits the German VAT. That construction applies to B2C goods orders through the marketplace where the seller is not established in the EU.
Outside that construction, everything works as before: a German business buyer wants a proper invoice from you with your USt-IdNr. A sale through your own webshop from the same German stock is your supply at 19% or 7%. Amazon moving your stock from a German to a Polish warehouse is an intra-Community transfer you must report. None of that appears on the platform's return; all of it belongs on yours.
Where sellers get burned
The expensive mistake is treating platform collection as a substitute for registration and skipping the filings. The Finanzamt sees marketplace data (platforms report under the DAC7 rules) and eventually writes: first an Aufforderung zur Abgabe, then estimated assessments with surcharges. At that point you are back-filing months of returns under deadline pressure instead of running a clean routine.
The second mistake is the reverse: charging customers 19% on marketplace orders where the platform already remits it, effectively paying the VAT twice or confusing your margins. Clean bookkeeping separates deemed-supplier orders from your own taxable sales, which is exactly what the monthly return we file does.
If your stock is already in Germany
- Confirm your exposure window. The registration duty started when the first unit arrived in a German warehouse. Months since then need catch-up returns.
- Register now, voluntarily. Coming forward before the Finanzamt writes is cheaper: no estimated assessments, negotiable surcharges, full input-VAT recovery.
- Reconcile the marketplace reports. Amazon VAT Transaction Reports separate deemed-supplier orders from your own supplies; the returns are built from that split.
- Hand it over. €1,199 per year all-in: German VAT registration, all monthly filings and the annual return, billed yearly starting at signup, back months at €79 each. Already registered? €79 per month (or €853 per year) once you already hold a German Steuernummer.

The tax-exempt deemed supplies to the platform (reported, not taxed), intra-Community stock movements between warehouses, B2B sales, sales through your own website, and input VAT you reclaim on imports, storage and fees. The monthly return is the container for all of it.
Often no: for goods shipped from outside the EU and sold B2C through a marketplace, the platform is deemed supplier and the import side is handled at the border or via the platform's IOSS. The analysis flips the moment you place stock in Germany or another EU country, so check again before joining any fulfilment program.
The deemed-supplier and § 25e liability rules apply to electronic interfaces generally, so the marketplace mechanics are the same. What differs is enforcement style and reporting formats, not the law.
Register and back-file. Voluntary catch-up keeps surcharges manageable (they are capped at 10% per return, €25,000 max) and preserves your input-VAT refunds. Waiting for the Finanzamt letter turns the same numbers into estimates plus enforcement.
