Every year around late May, business owners get the same sudden itch: “I need to buy a vehicle before June 30 to get a tax write-off.”
But if you head to a dealership looking for a brand-new car right now, you’re likely to hit a massive roadblock: delivery delays. If that shiny new asset isn’t physically in your possession by midnight on June 30, you can’t claim it this financial year.
That is why the used car market is the ultimate End of Financial Year (EOFY) cheat code. Used cars are sitting on lots or ready with private sellers right now, waiting to be driven away.
If you are looking to secure a used commercial vehicle or passenger car using finance before the clock strikes July, here is how to maximize your tax position without draining your cash reserves.
1. The $20,000 Instant Asset Write-Off Sweet Spot
For small businesses with an aggregated turnover of less than $10 million, the $20,000 Instant Asset Write-Off is locked in for this financial year. (And great news from the recent Federal Budget—this $20k threshold is set to become permanent!).
Because you are buying second-hand, a massive pool of highly reliable work vehicles, vans, and tools-of-the-trade cars fall right under that $20,000 threshold.
-
The Rule: If the vehicle costs less than $20,000 (ex-GST), you can deduct the entire cost from your taxable income this year.
-
The Catch: This applies per asset. You could technically buy two used vehicles under $20k each and write them both off completely.
2. What if the car costs more than $20,000?
Don’t worry, you don’t miss out. If your ideal used vehicle costs $25,000 or $40,000, it simply enters your small business general depreciation pool.
You will still receive a 15% deduction in the first year, even if you buy it in the very last week of June. The remaining balance then depreciates at 30% in subsequent years.
3. The Golden Rule: Paperwork Deduction
This is the single biggest trap buyers fall into every single year. Simply signing a finance contract on June 29 does not qualify you for a tax deduction.
The ATO is incredibly strict on this: the vehicle must be delivered and “first used or installed ready for use” for business purposes before July 1. Because used cars have virtually zero lead time compared to new factory orders, you actually have time to get the keys in your hand and legally claim the deduction.
4. Keep Your Cash Flow Safe with a Chattel Mortgage
You don’t need to empty your business bank account right before tax season to get these benefits. This is where smart financing comes in.
By utilizing a Chattel Mortgage:
-
You take ownership of the vehicle from day one (allowing you to claim the depreciation or instant write-off).
-
You can claim the GST component on your next BAS.
-
You preserve your hard-earned cash flow for winter, paying off the vehicle in manageable monthly installments.
The Bottom Line
The used car market gives you the speed you need to beat the June 30 deadline, but lenders get absolutely slammed in June. If you want to guarantee your finance is approved, settled, and the car is parked in your driveway before the cutoff, you need to act now.
