The ATO garnisheed your customers: debtor and merchant-facility notices

How a debtor garnishee works

A garnishee notice obliges a third party who owes you money to redirect it to the ATO. For a business, the ATO's usual targets are:

• Trade debtors — customers with your invoices on their payables ledger. The notice requires them to pay the ATO rather than you, up to the amount of your tax debt.
• Contract principals — the builder or head contractor you subcontract to, a platform that pays you, a managing agent collecting your rents.
• Merchant facilities — your EFTPOS or card provider can be required to remit a proportionate percentage of the funds processed through the terminal, skimming your takings before they reach your account.
• Banks — technically the same power aimed at your own accounts; that's covered separately under bank account garnishees.

No court order is needed, and the recipient is legally required to comply — your customer cannot simply take your side, however good the relationship. You should be sent copies of any notices issued, so you can establish exactly who received one.

One-off vs continuing notices

A notice can capture a debt owed at a point in time — the invoices your customer owes today — or it can be continuing, requiring the recipient to keep redirecting money as future amounts become owing to you, until your tax debt is paid or the notice is varied or withdrawn. Merchant-facility notices are continuing by nature: a set percentage of every settlement. A continuing notice on a major customer or head contractor effectively puts the ATO between you and your revenue line — which is precisely the pressure it's designed to create, and why these notices tend to force a resolution one way or the other within weeks.

Exposure isn't evenly spread. The businesses hit hardest are those with concentrated receivables: a subcontractor whose income flows through one head contractor, a consultancy with two anchor clients, a cafe whose takings are mostly card. One continuing notice to the right recipient can capture most of the revenue line in a single stroke. If that describes your business and ATO warning letters about an unpaid BAS debt are already arriving, treat a debtor garnishee as a live risk rather than a remote one — the warning-letter stage is when a payment arrangement is cheapest to strike, and it is far easier to prevent the notice than to talk customers through one after it lands.

Reputational damage control: what to tell customers

The real cost of a debtor garnishee is that it announces your tax trouble to the people you least want to know. You can't un-ring the bell, but you can control the story:

1. Call the affected customers before they call you. A short, factual heads-up beats them discovering the notice cold. Silence reads as insolvency; a plan reads as a rough patch being managed.
2. Keep the script simple and true. Something like: "You'll have received a notice from the ATO directing some payments to them — it's valid, please comply with it. We're in the middle of resolving a tax matter and expect it to be sorted shortly. It doesn't affect our work for you." Never ask a customer to ignore the notice.
3. Confirm the mechanics. Payments a customer makes to the ATO under the notice discharge their debt to you — they aren't paying twice, and you should credit their account accordingly. Making that explicit calms the payables team on the other end.
4. Contain the circle. The notice goes to named recipients, not the market. Deal with those relationships directly rather than broadcasting an explanation nobody else needs.

Cash-flow triage while the notice is in force

A garnishee on your receivables can starve wages and supplier payments within a payroll cycle or two. Triage, in rough order:

• Map the exposure. Which debtors got notices, one-off or continuing, and what percentage is the merchant facility remitting? The copies you were sent tell you; the ATO will confirm. Then build a two-week cash forecast on the reduced inflows — you need to know today whether the next pay run clears, because that answer shapes every conversation that follows.
• Protect wages and super first. Missing employee super creates new personal exposure for directors through the director penalty regime — don't fix one ATO problem by creating a worse one.
• Don't pile up fresh tax debt. Keep current BAS lodged and paid if at all possible; a growing BAS debt behind the garnishee undermines any negotiation.
• Be honest about viability. If the business only works while the ATO isn't being paid, the garnishee hasn't caused the problem — it's revealed it. That's the point to look at rescue options such as small business restructuring, which deals with the whole debt rather than this month's cash squeeze.

Getting the notice varied or withdrawn

The ATO issues debtor garnishees when it has concluded you won't engage voluntarily — so demonstrated engagement is what reverses it. The ATO can vary a notice (lower percentage, fewer recipients) or withdraw it where the debt is being addressed and hardship or disproportionate damage is shown. The package that usually works: all lodgments current, a realistic payment plan proposal backed by real numbers, evidence the garnishee itself is destroying the capacity to pay (lost contracts, wages at risk), and a request for withdrawal or variation as part of the arrangement. Where interest has compounded the debt badly, ask about GIC remission in the same conversation. If you're not sure whether negotiation or a formal restructure is the right lane, start with what's my situation?
