Im not sure any of the states have been updated with the later withdrawal date yet. Give them a voucher or they can pay it online themselves if they need to wait.
The due date change from 4/15/21 to 7/15/21 for IND or BUS has not been implemented by the state agency yet. As of now, you can set up the payment to be made on the current date or a future date but not beyond 4/15/21 (as it was the original filing/paying due date).
Until the state updates their system, taxpayers that elect to make payments after 4/15/21 will need to make the payments electronically or with a printed voucher.
