When an ABN is entered for a Contractor (Employee), it is automatically checked against the inbuilt algorithm provided by the ATO.

If e-PayDay® states your Contractors ABN is invalid, the ABN entered does not match the ATO’s algorithm.

Refer to the Contractor to ensure the ABN has not been entered incorrectly.

If the ABN is exactly as provided by the Contractor, advise the Contractor to contact the ATO to confirm they have not provided the incorrect number.
