No-ABN withholding: why 47% gets held back, and how to avoid it

If you invoice a business without quoting your ABN, it may have to send 47% of your payment to the ATO instead of to you. Here's when that happens and how to stop it.

The rule

The ATO says payers must withhold 47% of the total payment for a supply unless one of these applies:

Payers may also have to withhold if they have reasonable grounds to believe the ABN quoted is invalid. If a payer doesn't withhold when required, it may have to pay a penalty equal to the amount it should have withheld.

Exceptions (via a "Statement by a supplier")

A supplier can give a Statement by a supplier instead of an ABN only if one or more of these applies:

Supplier: how to avoid it

Quote your ABN by the time you're paid. The easiest way is to put it on every invoice. If you've applied but don't have it yet, you can ask the payer to hold the payment until you quote it. That's a matter between you and the payer. Any amount withheld is shown on a payment summary, which you can use to claim a credit in your tax return.

Payer: what you must do

Register for PAYG withholding, withhold 47%, report and pay it on your activity statement, give the supplier a PAYG payment summary – withholding where ABN not quoted, keep a copy, and lodge the annual report.
