Inland Revenue has confirmed a planned internal system upgrade over the weekend of Saturday 6 – Sunday 7 December 2025.
Their online services, including myIR, Gateway Services, and self-service phonelines, will be unavailable from 6:00am Saturday 6 December until approximately 6:00pm Sunday 7 December.
Phonelines and offices will reopen as normal on Monday 8 December.
Key Details for Bookkeepers
Drafts in myIR
Any drafts saved in myIR will remain available and accessible as usual once services are restored.
Website and Payments
Inland Revenue’s website will remain available.
You and your clients will still be able to make payments through your bank during the shutdown period.
Service Resumption
Phonelines and offices return to normal hours on Monday 8 December.
What this means for you
If you or your clients have time-sensitive work planned, make sure anything urgent is submitted before 6:00am Saturday 6 December to avoid disruption.
Otherwise, all saved drafts will remain intact, and normal service will resume after the upgrade window.
As always, keep these dates in mind when planning client work and ensure submissions and enquiries are completed ahead of the outage.
