For whom does smartsteuer fit, and for whom the alternative?

smartsteuer fits if you want to file your annual returns online and pay only on filing.

VAT GPT fits if you sell on Amazon or eBay to private customers in other EU countries. If you are established only in Germany and these distance sales (together with certain electronic services) exceed 10,000 € net in the previous or the current year, VAT of the country of destination applies (§ 3c(4) UStG); instead of registering in each country, you can report it through the OSS scheme with the BZSt (§ 18j UStG, BZSt: One-Stop-Shop). VAT GPT reads the marketplace reports and calculates VAT for Germany and the EU from them. VAT GPT is not bookkeeping or order software and does not replace tax advice.

What this means for you: With no marketplace sales abroad you may not need the alternative at all.

How does VAT GPT help here?

Upload: Amazon and eBay reports and invoices; the AI reads amounts, countries and tax rates.
Check: You review and confirm the values.
Send: With Pro, through ELSTER to the tax office and the OSS return to the BZSt.

Not included: no tax advice. Plans are Free, Go and Pro (49 € a month or 444 € a year, incl. VAT). Try it free
