Rockingham, Armadale, and Augusta Margaret River Adopt Gross Rental Value for Property Taxes

Title: Rockingham, Armadale, and Augusta Margaret River Adopt Gross Rental Value for Property Taxes Body: Several Western Australian councils, including the City of Rockingham, the City of Armadale, and the Shire of Augusta Margaret River, are shifting to Gross Rental Value (GRV) as the basis for property tax assessments. This change, documented in recent WA Government Gazettes, has the potential to significantly impact homeowners and businesses in these areas. Understanding the implications of this shift is crucial for property owners to anticipate potential changes to their rates bills.

What is Gross Rental Value (GRV)?

Gross Rental Value (GRV) is an assessment of the annual rent a property could reasonably be expected to earn if it were available for lease. This contrasts with Unimproved Value (UV), which is based solely on the value of the land, excluding any buildings or improvements. The Valuer General provides information on the difference between UV and GRV; GovScanner encourages users to consult the Valuer General's resources for a detailed explanation. A move to GRV can result in significant changes to rates, particularly for properties with substantial improvements, as the value of the buildings is now factored into the assessment.

Rockingham's Transition to GRV

The City of Rockingham has announced its shift to GRV for property tax assessments in several recent gazette notices. One notice specifically states, "Basis of Rates — City of Rockingham — UV to GRV," indicating a complete transition from Unimproved Value to Gross Rental Value. Another notice, "Basis of Rates — City of Rockingham — Lots 277 to 305 on Deposited Plan 430333," further clarifies the application of GRV to specific land parcels within the city. This targeted approach suggests a phased implementation or specific areas where the transition is being prioritised. Residents in Rockingham should pay close attention to these changes, as they could see significant variations in their rates depending on the rental potential of their properties. For more information, property owners should consult the City of Rockingham's website for budget information and relevant council documents.

Armadale Adopts GRV Under Section 6.28(1)

The City of Armadale is also implementing GRV for property tax assessments, as indicated in the gazette notice "Basis of Rates — City of Armadale — Section 6.28(1)." The reference to Section 6.28(1) likely pertains to a specific provision within the Local Government Act 1995 that empowers councils to determine the basis of rates. This move aligns Armadale with other metropolitan councils that utilise GRV. Property owners in Armadale should familiarise themselves with Section 6.28(1) of the Local Government Act 1995 and consult the City of Armadale's website for detailed information on how GRV will be applied and how it will impact their rates. Understanding the legal basis for this change is crucial for ratepayers to assess its fairness and potential implications. Prior GovScanner stories on council rate changes can provide additional context on similar transitions in other local government areas.

Augusta Margaret River Joins the GRV Trend

Extending beyond the metropolitan area, the Shire of Augusta Margaret River is also adopting GRV, as confirmed in the gazette notice "Basis of Rates — Shire of Augusta Margaret River — Gross Rental Value." This decision indicates a broader trend among WA councils to utilise GRV for property tax assessments. For a regional centre like Augusta Margaret River, this shift could have significant implications for the local economy, particularly for businesses that rely on tourism and rental income. The Shire of Augusta Margaret River's website should be consulted for specific details on how GRV will be implemented and how it will affect ratepayers in the region. The adoption of GRV in Augusta Margaret River highlights the widespread nature of this change across Western Australia.

The shift to GRV by these councils represents a significant change in how property taxes are calculated. It is essential for property owners in Rockingham, Armadale, and Augusta Margaret River to understand the implications of this transition and how it will affect their rates bills. Monitoring council announcements and engaging with local government representatives will be crucial for navigating these changes. The Cook Labor Government's policies on local government funding and property valuation may also play a role in how these changes are implemented and their ultimate impact on ratepayers.
