The Tax Commissioner has confirmed that the registration deadline for the April and May JobKeeper payments has been extended to 31 May 2020. See the ATO's JobKeeper homepage
While the extra time is very welcome, it will not remove the urgency to determine eligibility for April 2020 JobKeeper payments.
To be eligible for April JobKeeper payments, employers will need to ensure that staff have been paid at least $1,500 for the first two JobKeeper fortnights (30 March – 12 April and 13 April – 26 April) by the end of April.
Unless the situation is clear cut, employers should be careful about making top up payments to staff until they have assessed their eligibility and have received the JobKeeper nomination forms back from staff (unless they want to risk being ineligible and not being reimbursed for these top up payments).
