The Letter You Can't Ignore
If you've received a Notice of Assessment with a large "Amount Payable," the worst thing you can do is bury it under a pile of bills.
The ATO is surprisingly reasonable if you contact them **before** the due date. Once you miss the deadline, the automated "Firmer Action" system kicks in, which can lead to garnishee notices (where they take money directly from your bank account or wages).
How to Set Up an ATO Payment Plan
For debts under $100,000, you can usually set up a payment plan yourself via MyGov or the ATO app.
The Setup Checklist:
- Upfront Payment: Be prepared to pay at least 10-20% immediately.
- Installments: You can spread the rest over 12-24 months.
- Lodge First: You cannot set up a plan until the return or BAS is lodged.
The 11% Interest Trap
The General Interest Charge (GIC) is high—currently around 11%. It is added to your debt every single day.
A $10,000 debt left for a year can grow by over $1,100 purely in interest. This is why paying as much as possible upfront is critical.
How to Ask for a "Waiver"
If this is your first time having a debt or being late, you can request a Remission of Interest or Penalties.
How to Avoid a Tax Debt Next Year
Most tax debt comes from two things: Not setting aside GST/Tax, and **missing deductions**.
