FAQ
We are often asked this
Do you have questions about tax law or the offers from iust.ai? We have the answers:
Tax law is part of public law and regulates the assessment, collection, and administration of taxes. It also determines the rights and obligations of taxpayers toward the tax authorities. It includes both substantive regulations (e.g., which taxes are levied and at what amount) as well as formal procedural law (e.g., tax returns, assessments, and objection procedures). Important components of tax law include, among others:
  • Fiscal Code (AO): Basis for tax procedures, tax assessments, audits, and dealings with the tax office
  • Substantive tax laws: Regulations on individual tax types such as income tax, VAT, or corporate tax
  • Obligations of taxpayers: Filing of tax returns, payment of taxes, and participation in audits
In German tax law, 7 basic tax types are often distinguished. These include income tax on private income, corporate tax for legal entities, VAT on deliveries and services, as well as trade tax, which is levied on businesses. Additionally, there is property tax on real estate, inheritance and gift tax on asset transfers, and motor vehicle tax for owning vehicles. Which tax types are relevant in individual cases depends on the personal or business situation.
