As a tenant in Austria, it can be important to report changes such as address, household, or income changes in a timely manner. Often, deadlines, rent calculation or the deliverability of legal letters depend on this. This page explains in simple steps which changes are typically relevant, which deadlines apply and how to collect evidence sensibly. You will receive practical tips on how to inform in writing, which form or proof obligations may arise and how to communicate to avoid misunderstandings with the landlord. At the end you will find concrete action steps and pointers to official bodies if a dispute arises.

Which changes should tenants report?

  • Address change (new residence address for deliveries)
  • Change in household composition (people moving in or out)
  • Change in income or cost allocation
  • Change of bank details for rent payments
  • Structural changes or permanent modifications to fixtures (e.g. renovations)
Detailed documentation increases your chances of success.

How should you report changes?

Written notification to the landlord is the safest. State exactly which change occurred, from what date, and attach relevant proof. Note the date of sending and keep a copy.

  • In writing by letter or by e-mail with read receipt
  • If possible: by registered mail or delivery confirmation
  • Attach proofs (registration certificate, bank statement, signature of the person moving in)
  • Request a written confirmation of receipt from the landlord
Keep copies of all letters and receipts.

Deadlines and legal basis

Report changes as soon as possible; specific deadlines may be regulated in the lease or arise from the Mietrechtsgesetz (MRG).[1] Do not underestimate how important deadlines can be for deliveries or rent calculations.

What to do if the landlord does not respond?

Send a reminder and set a clear deadline for a reply. If the landlord still does not respond or refuses important information, document your attempts and consider legal steps at the competent district court.[2]

Respond quickly to payment reminders or notices of termination.

Key takeaways

  • Report changes in writing and promptly.
  • Secure proofs and request confirmations of receipt.
  • If there is a dispute: document and consider legal help or court contact.
