Planned system outage - 12 September 2026 | Our online services including myIR, self service phone lines and gateway services will be unavailable on Saturday 12 September, 2026 from 1pm to approximately 10.30pm while we complete a planned system update. We apologise for any inconvenience this may cause.

This week, we began remediation to address the issue of debit interest being charged on provisional tax from the wrong due date.

We are still analysing customer data regarding other provisional tax issues. We plan to work out remediation and take any necessary actions by the end of the month.

We apologise for any inconvenience and concern this may have caused, and are grateful for your understanding as we work through this.
