PAYG tax details apply to payees who have tax withheld from their earnings by their employer under the Pay-As-You-Go tax scheme.
When a payee who is subject to PAYG withholding commences employment with a pay company, the payee must hand in a Tax File Number (TFN) Declaration form that is then used by payroll staff to populate the details on the Portal > Pay > Payee > Payee Maintenance > Payee Entry > PAYG Tax Details screen.
At the time of commencing employment the payee may indicate on their TFN Declaration form that they have applied to the ATO for a TFN. In such cases it is necessary to update the payee's TFN once the payee provides it.
Once the payee has been paid (included in a closed pay batch) their PAYG tax details are locked down for the corresponding payee details validity period and cannot be modified for that period.
However, if the payee provides a TFN after they have already been processed in one or more pay batches, the TFN and TFN signature date can be updated despite all other tax details being locked down. To modify any other tax details, you must create a new payee details validity period.
