Compromise of tax debt: can you really settle with the ATO for less?

What a compromise actually is

A compromise is a formal agreement where the ATO accepts a lesser amount in full settlement of an undisputed tax debt — the debt is correct, you simply can't pay it all, and the Commissioner decides taking your best offer beats the alternatives. The rules are set out in ATO practice statement PS LA 2011/3.

Be clear about what it isn't. It isn't the American "offer in compromise" system you've seen in late-night ads. It isn't a negotiation the ATO enters because you hold out long enough. And it isn't debt forgiveness for hardship — that's a separate release process, for individuals only. Compromise is a commercial decision by a creditor, made rarely and on the creditor's terms.

The criteria: why the door is so narrow

Under PS LA 2011/3, a compromise is realistically only considered when all of the following stack up:

1. You genuinely cannot pay in full — ever. Not "not right now". If a payment plan over a reasonable period could clear the debt, compromise is off the table.
2. The alternatives have been examined and don't fit. Payment arrangements, hardship release (for individuals), and formal insolvency are all considered first. Compromise is the last door, not the first.
3. Your offer beats the insolvency outcome. The ATO models what it would recover if you went bankrupt or the company was liquidated — your net realisable assets, recoverable transactions, likely dividends. The offer generally has to be at least that amount, and preferably more. An offer below your net asset position tells the ATO it does better by enforcing.
4. You come with clean hands and full disclosure. Complete, verifiable financial disclosure — assets, liabilities, income, and where the offer money comes from. Debts arising from fraud or evasion, recent asset-shuffling, a prior compromise, or a recent insolvency arrangement will generally kill the application.
5. Other creditors don't get a windfall. The ATO won't take a haircut so that other creditors — or you — end up better off at the Commonwealth's expense.

The process, if you genuinely qualify

There's no application form. A compromise proposal is a written submission — normally prepared by an adviser — containing the offer, complete financial disclosure, evidence of the source of funds (often a third party, such as family, since your own assets are already counted in the insolvency comparison), and the argument for why acceptance beats enforcement. Expect the ATO to verify everything, ask for more, and take months. Two traps worth knowing even at this stage:

• A compromise can be undone if your disclosure turns out to have been false or incomplete — the balance comes back.
• It doesn't automatically release parallel liabilities. Compromising a company's debt doesn't release directors from director penalty liabilities unless that's expressly dealt with.

Where tax debts actually get cut

Here's the part the settlement ads leave out: the ATO accepts less than 100 cents in the dollar all the time — just through structured processes, not private handshakes.

• Companies: small business restructuring. An SBR plan typically offers creditors a fraction of the debt over up to three years, the ATO votes (and commonly votes yes on well-built plans), and the balance is legally extinguished while you keep trading. For viable companies under $1m in liabilities this is the mainstream "compromise" route — see small business restructuring and SBR vs liquidation.
• Individuals and sole traders: hardship release for income tax debt, or formal insolvency alternatives — debt agreements and personal insolvency agreements — where the ATO votes as a creditor on a part-payment proposal. The full picture, including bankruptcy itself: bankruptcy and sole trader tax debt.
• Everyone: interest and penalties. On an old debt, GIC and penalties can be a third or more of the balance, and they're the genuinely negotiable component — see interest remission and penalty remission. Remitting them achieves a real "discount" without any compromise at all.

Managing expectations

If you owe the ATO and can't pay, the realistic ladder looks like: payment plan → interest and penalty remission → restructuring or insolvency alternatives → and only in rare, well-evidenced cases, a formal compromise. Skipping to the bottom rung wastes months you may not have — especially if unlodged BAS or super is quietly converting company debt into locked-down personal debt in the meantime.
