Why these tools?
In used-car trading, one detail can decide both your margin and your exposure to a tax adjustment. Our tools apply the logic explained in the Autaxo knowledge base and help reduce technical mistakes involving § 25a, exports and invoicing. They provide an initial assessment and do not replace individual tax advice.
