Quick answer
For tax debts of $200,000 or more, you generally can't set up a payment plan through online services — you have to contact the ATO. Expect questions about your finances, cash flow and viability, and possibly a request for security such as a mortgage over property or a bank guarantee. GIC keeps compounding on the balance throughout. Property-secured funding is the main alternative, paying the ATO out in one go.
Key points
- Online plans are for debts under $200,000; larger debts need direct contact with the ATO.
- Be ready with financial statements, a cash-flow forecast and lodgements up to date.
- The ATO may ask for security: preferably a registered mortgage or an unconditional bank guarantee.
- Large debts may also cross the $100,000 / 90-day credit-reporting threshold.
Why does $200,000 change things?
The ATO’s online services let businesses arrange their own payment plans when the debt is under $200,000. It’s quick and doesn’t involve explaining yourself to anyone. Once the debt reaches $200,000, the ATO wants to talk. That isn’t a punishment; it’s the ATO doing what any large creditor would do before extending more time on a significant sum.
At this level, the debt has usually crossed another threshold too. If $100,000 or more has been overdue for more than 90 days and you aren’t effectively engaging with the ATO, it can be disclosed to credit bureaus after a 28-day warning. Getting an arrangement in place — or paying the debt out — prevents that.
What will the ATO want to know?
Prepare as you would for a meeting with a bank. The ATO will typically want to understand:
| Topic | What to have ready |
|---|---|
| The debt | Statement of account for each account; any disputed amounts |
| Lodgements | Every BAS and return lodged, or a firm date for outstanding ones |
| Income and costs | Recent financial statements or management accounts |
| Cash flow | A 12-month forecast showing instalments and new tax obligations |
| Assets and other debts | Property, equipment, other lenders, creditors in arrears |
| Why it happened | A short, honest explanation |
| What’s changed | Pricing, costs, staffing, tax set-aside account |
| Your proposal | A realistic instalment amount and term |
An accountant or registered tax agent can prepare and present this, and many people find that helps. Remember that anyone negotiating with the ATO on your behalf for a fee must be a registered tax agent — you can check on the Tax Practitioners Board register.
Will the ATO ask for security?
It might. Where a standard arrangement can’t be reached, the ATO can accept security for an instalment arrangement or a deferral. Its preferred forms are:
- a registered mortgage over freehold property; or
- an unconditional bank guarantee from an Australian bank.
A secured plan can buy significant time. The trade-offs are that GIC continues to compound daily on the outstanding balance (and isn’t deductible if incurred from 1 July 2025), the debt stays with the ATO, and the arrangement still depends on you keeping every new obligation current.
How does funding compare at this size?
For large debts, the comparison is between giving the ATO security for a plan and giving a lender security for a loan that pays the ATO out. The main differences:
| Secured ATO plan | Property-secured loan | |
|---|---|---|
| Who you owe | The ATO | A lender |
| Interest | GIC, daily compounding, reset quarterly; not deductible from 1 July 2025 | The loan’s cost; interest may be deductible |
| If something goes wrong | Default — whole balance due, firmer action | The lender’s terms and arrears process |
| Director penalties | Not remitted by the plan itself | Removed when the company liability is paid |
| Credit reporting | Avoided while complying | Removed once paid |
| Approval process | ATO assessment | Lender assessment, valuation |
Property-secured business loans run from $20,000 to $5,000,000, with funding possible in as little as 24 hours once the lender has what it needs. See funding large ATO debts.
What if there’s a director penalty notice as well?
Then timing matters more than anything else. A plan doesn’t remit a director penalty. Within 21 days of the notice, the remitting outcomes are payment in full, appointing an administrator, appointing a restructuring practitioner, or beginning to wind up. If any amount is locked down, only payment works. A large debt plus a DPN is often exactly where funding earns its place. Read your first 21 days before you call anyone.
An illustrative example
A family-owned wholesaler owes the ATO a little over $300,000 across activity statement and income tax accounts after a major customer went into administration owing it money. The ATO is open to a secured plan, but it would run for several years with GIC compounding throughout. The directors instead use a second mortgage over the warehouse property to clear the activity statement debt, removing the director penalty exposure, and agree a shorter ATO plan for the income tax.
How do you present the business to the ATO?
The ATO’s assessment of a large plan is, in practice, an assessment of credibility. The businesses that tend to get workable arrangements present:
- A clear cause — one paragraph, with dates.
- Evidence of change — a new pricing model, a cost review, a dedicated tax account, monthly BAS reporting.
- A realistic schedule — instalments that are demonstrably affordable alongside new obligations, not the smallest number you think the ATO will accept.
- Security, if available — offering it proactively can show commitment.
- A professional in your corner — an accountant or registered tax agent who knows the numbers.
While the conversation with the ATO continues, keep every new BAS lodged and paid on time. Nothing undermines a large-plan request faster than a new debt appearing during the negotiation.
Keep the conversation documented
Large-plan negotiations can take several calls. Keep notes of each one, confirm agreements in writing through online services where possible, and diary every instalment and review date.
Want to compare your options properly?
If your ATO debt is $200,000 or more, a short conversation can save a lot of time. Start your enquiry here — there’s no credit check to enquire, your information isn’t shopped around to lenders, and a real person will help you weigh a secured plan against funding. Accurate figures for each ATO account and any property make that first call far more useful.
Frequently asked questions
Why can't I set up a plan online for more than $200,000?
The ATO's online self-service is designed for debts under $200,000. For larger debts, it wants to understand the business's position before agreeing to an arrangement, so you need to contact it by phone or through your tax agent.
What will the ATO ask for on a large payment plan?
Typically information about income, expenses, assets and other debts, a realistic instalment proposal, evidence the business can meet new tax obligations, and lodgements up to date. For some arrangements it may ask for security.
Does the ATO accept property as security for a payment plan?
Yes. The ATO's preferred securities for secured arrangements are a registered mortgage over freehold property or an unconditional bank guarantee from an Australian bank.
Is it better to fund a $300,000 ATO debt or go on a plan?
It depends on the total cost of each, how long the plan would take, whether director penalties are involved and how much certainty you want. Compare the GIC on the plan with a real loan quote before deciding.
