Indexed Rent in Austria: Tenant Rights

Rent & increases (reference rent, categories, form) 2 min read · published September 10, 2025
Many tenants in Austria face indexed rent and wonder how to respond when a landlord announces an increase. This article explains in clear terms what indexed rent means, which deadlines and formal requirements apply, and which tenant rights protect your home. I describe concrete steps: how to check the calculation, which documents help, how to meet deadlines and when to involve a lawyer or mediation service. The aim is to empower tenants to make informed decisions and avoid costly mistakes. The guidance applies specifically to residential lettings in Austria and is based on applicable tenancy law.

What is indexed rent?

Indexed rent is a reference point for rent calculation and may apply in certain cases depending on the tenancy agreement and the Tenancy Act (MRG).[1]

In many cases indexed rent is tied to statutory rules.

How can tenants check a proposed increase?

If the landlord announces an increase, first verify the calculation in writing and request supporting documents. Pay attention to any deadlines in the notice and the required form of notification.

Keep all letters, emails and receipts organized and easily accessible.
  • Request the exact calculation and all supporting documents from the landlord in writing.
  • Check whether the tenancy falls under the MRG and which contract clauses apply to indexed rent.
  • Document communications, photos and receipts as evidence for any later steps.

What to do in case of dispute or missed deadlines?

If a dispute arises, tenants can first contact mediation services or the competent district courts; judicial procedures are handled by the responsible district court, and information on jurisdictions and procedures is available from justice authorities.[2] Specific procedural steps can be done using electronic forms and submissions.[3]

Respond to official letters within the deadlines to avoid losing claims.
