November is a key month for small businesses and individuals to stay on top of obligations, plan ahead, and make the most of tax and super opportunities. Here’s what to focus on this month.
Increased focus on data‑matching and undeclared income
The ATO continues to expand its data‑matching programs, including rental income, overseas merchant transactions, and other third‑party data feeds. Letters are being issued to taxpayers whose income appears undeclared.
Tip: Individuals with rental properties should check that all income has been declared. Small businesses should ensure bookkeeping is accurate and reconciled.
Vehicle use & fringe benefits compliance for small business
The ATO has clarified that vehicles, including dual‑cab utes, are not automatically exempt from fringe benefits tax (FBT). Eligibility depends on the vehicle type and the extent of private use.
Tip for businesses: Keep accurate logs of vehicle use and separate private from business use to avoid FBT issues.
Deduction claims & record‑keeping under the spotlight
Overclaimed expenses, private vs business use confusion, and weak supporting records remain key compliance targets.
Tip: Maintain receipts and digital records for all deductions and clearly apportion any mixed‑use expenses.
GST, property & enterprise tests
The ATO has released updated guidance for property transactions, including land subdivisions and developments. GST treatment depends on whether an activity constitutes an “enterprise.”
Tip: Seek advice early on property sales or subdivisions to ensure GST compliance.
