Operating Costs: Billing for Tenants in Austria

Service charges & settlements 3 min read · published September 10, 2025

As a tenant in Austria, it is important to understand the differences between advance payments and flat fees for operating costs. Many rental agreements provide for advance payments or flat-rate arrangements, but the actual statement, receipts and deadlines determine whether additional payments or refunds follow. This guide explains in plain language the obligations of landlords and tenants, how to review your statement, which receipts you can request and when deadlines must be observed. I also describe practical steps for communicating with the landlord and how to proceed in case of incorrect statements or disputes. The aim is to give tenants in Austria clear actions and guidance so they can better enforce their rights regarding service charge statements.

What are operating costs?

Operating costs regularly include recurring costs such as heating, hot water, waste disposal, building cleaning and building insurance. Whether a cost item is allocable is often determined by tenancy law and the Mietrechtsgesetz [1]. The type of advance payment affects how the settlement is performed at the end of the accounting period.

In most cases, operating costs include water and waste fees in addition to heating.

Advance payments vs flat fees: Differences

  • Advance payments are prepayments that are later offset against the actual statement.
  • A flat fee is a fixed amount that does not automatically allow additional or refund payments unless a contractual balancing obligation exists.
  • With advance payments you can request receipts and detailed statements; with flat fees access to itemized evidence is often more limited.
  • Deadlines for objections and claims differ; respond promptly if something is unclear.
Always request the receipts for the statement in writing if something seems unclear.

Rights, duties and deadlines

Tenants have the right to inspect accounting documents and request copies. Check the statement for plausibility: are consumption figures comprehensible? Have advance payments been taken into account? If in doubt, first contact the landlord in writing and set a deadline.

Respond to formal letters in time to avoid missing a deadline.

Receipts and evidence

  • Request full receipts, such as heating bills, maintenance contracts and invoices.
  • Record payment dates and keep receipts and bank statements as proof.
  • If no agreement is reached, legal action before the district court may be necessary; there are deadlines and formal requirements for this [2].
Detailed documentation increases the chances of success in a review or legal clarification.
