If you are making a payment or adding a bank account in myIR, a direct debit authority will first need to be set up. This has been a requirement since March 2020.
Setting up a direct debit with IRD gives them the authority to deduct funds from your bank account if you owe money to them.
Our advice: Do not add or change bank accounts or make payments in myIR after 31 March 2020, unless you are happy to set up a direct debit authority with IRD. It is best to make your payment by credit card or use the online banking service with your own bank.
