Rent & increases (reference rent, categories, form) 2 min read · published September 10, 2025
As a tenant in Austria, the idea of renting your flat short-term can be attractive — but there are legal obligations you should know. This guide plainly explains which permits and contractual rules apply, what rights tenants have regarding house rules and landlord consent, and how to reduce risks like eviction or contractual penalties. You will learn how to obtain consent formally, which tax and registration aspects are relevant, and how documentation and communication help avoid disputes. The text includes practical checklists, deadlines, procedural notes and examples from practice.

Legal Basis

Short-term letting can be affected by the Mietrechtsgesetz (MRG) and civil law rules[1]. District courts are responsible for termination proceedings and disputes[3]. Also observe registration duties and possible tax consequences.

Landlord Consent

Many rental agreements require landlord consent. Without consent you risk breaching the contract or eviction. If the contract says nothing, clarify written form, deadlines and potential fees with the landlord.

Keep all messages in writing and dated.
  • Obtain written consent from the landlord or an explicit contract amendment.
  • Collect documents: lease, correspondence, house rules and advertisements.
  • Check the house rules for prohibitions or restrictions on short-term letting.

Registration and Taxes

Short-term letting may require registration and can trigger tax obligations. Find out about municipal registration duties and possible income or sales tax liabilities.

Undeclared income can have tax and contractual consequences.
  • Check whether you must declare income to the tax office and whether VAT applies.
  • Ask the municipality about registration or reporting requirements.

Practical Steps for Tenants

This checklist helps you act safely and transparently.

  • Gather all relevant documents and receipts in advance.
  • Obtain written consent or an amendment agreement from the landlord.
  • Clarify responsibilities and deadlines with the municipality and tax office.
Detailed evidence strengthens your position in disputes.
