IR system issue: Review myIR for UOMI and penalties

Inland Revenue (IR) has informed us that taxpayers who filed tax returns between 17 March and 17 April 2025 remain liable for use-of-money interest (UOMI) and late payment penalties. IR experienced a system issue during this period, which meant UOMI and penalties were not displaying correctly on the myIR accounts of many taxpayers.  

We understand IR has now updated the impacted accounts to correct this error, but may not have notified you yet.  

What should I do now? 

Check the myIR accounts for any taxpayers whose returns you filed between 17 March and 17 April. 

If they have UOMI and penalties on their accounts, contact us to purchase any tax shortfalls to reduce their interest exposure and eliminate late payment penalties. The last payment date for clients with a 7 April terminal tax date to settle any underpaid 2024 income tax liabilities with Tax Traders is Wednesday 18 June.  

What if a taxpayer has already paid IR? 

If any taxpayers have already paid their liability based on the incorrect information that was previously showing on their account, IR says it won’t remit UOMI and penalties. IR maintains taxpayers and tax agents are responsible for paying the correct tax at the correct time and a system display issue does not change that obligation.  

We are working with IR to find a way for a taxpayer to have their payment to IR refunded so they can purchase the required tax through Tax Traders. This will ensure tax can be purchased at the correct effective dates.

Please let us know if you have any taxpayers impacted by IR’s system issue. Our team will be happy to help you.
