In short

WISO Steuer: tax-return program with EÜR, VAT, advance VAT returns and trade tax; Vorteils-Abo EUR 35.99 per year, single purchase EUR 45.99 for one tax year.
VAT GPT: reads Amazon and eBay reports, works out VAT and OSS and, with Pro, sends.
Decision: fill in returns once a year, or process marketplace figures on an ongoing basis.

What does WISO Steuer offer the self-employed per its own site?

The self-employed page states, among other things (WISO Steuer: self-employed, German):

Scope: "Von USt & USt-VA über ESt & EÜR bis GwSt" (from VAT and advance VAT returns through income tax and EÜR to trade tax).
Included returns: "Bis zu 5 Erklärungen pro Jahr ohne Aufpreis – auch für mehrere Betriebe" (up to 5 returns a year at no extra charge, also for several businesses); the list names income tax return, Einnahmen-Überschuss-Rechnung, VAT return, advance VAT returns and trade tax return.
Transmission: the comparison table lists "Amtlich anerkannte Datenübertragung (§ 87c AO)".
Receipts: "Rechnungsfoto machen oder E-Rechnung hochladen" (take a photo of an invoice or upload an e-invoice).
AI: "SteuerGPT - dein persönlicher KI-Berater" in both paid variants.
The retrieved page does not mention OSS. That says nothing about whether WISO Steuer supports it elsewhere.

What this means for you: per its site, WISO Steuer guides you through the annual returns; the page does not name marketplace reports as a source.

What does WISO Steuer cost in a price comparison?

Prices per the provider, retrieved 29 October 2026; the page does not say whether they include VAT (WISO Steuer: self-employed, German):

Variant	Price	Term per the site
WISO Steuer trial	EUR 0.00	pay only when you submit the return
WISO Steuer Vorteils-Abo	EUR 35.99 per year ("im günstigen Jahresabo")	"Jederzeit kündbar" (cancellable at any time)
WISO Steuer single purchase	EUR 45.99 one-off	"Einmalige Abgabe für ein Steuerjahr" (one submission for one tax year)
VAT GPT Free	basic functions	–
VAT GPT Go	30 days free with all Pro functions	–
VAT GPT Pro	EUR 49 per month or EUR 444 per year, incl. VAT	send VAT return, OSS, EÜR, trade tax and income tax

A dash ("–") means: not stated explicitly. WISO prices per tax year, VAT GPT Pro monthly or annually; the models are not directly comparable.

What this means for you: if you file once a year, a yearly price is enough; if you file VAT returns monthly, what the price includes is what counts.

For whom does WISO Steuer fit, and for whom the alternative?

WISO Steuer fits if you go through the returns once a year and have your figures prepared.

VAT GPT fits if your figures sit in Amazon and eBay reports:

Import the reports as CSV and split VAT for Germany and the EU (OSS).
Create the VAT return, OSS return, EÜR, trade tax and income tax.
With Pro, send via ELSTER, and the OSS return to the Federal Central Tax Office (BZSt).

The VAT return goes electronically to the tax office (§ 18(1) UStG, German); the EÜR is the profit calculation under § 4(3) EStG (German).

What this means for you: if marketplace reports rather than single receipts are your source, a tool that reads them directly saves work.

How do I work with VAT GPT?

The method: Upload – check – send.

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

What this means for you: the Go plan (30 days with all Pro functions) is enough to run a real month.
