IRD Key Message Contact Update NZ 2026 – What Tax Agents Need to Know

New Zealand’s Inland Revenue (IRD) has introduced an important update affecting tax agents, accountants, bookkeepers, and intermediaries using myIR client lists.

Following the April 2026 system release, some client contact details shown in myIR may now be outdated. To improve communication accuracy, IRD now requires agencies to assign a Key message contact for each client list.

This update ensures IRD web messages and phone communications are sent to the correct staff member responsible for client matters.

For businesses managing tax compliance, payroll, GST, and filing obligations, keeping myIR contact information updated is becoming increasingly important.

The Key message contact is now the primary person IRD will contact regarding a specific client list inside myIR.

IRD will:

• Send web messages to that person’s myIR login
• Use the phone number attached to that web logon as the primary contact number

This means agencies should ensure the correct staff member is assigned to avoid missed messages or compliance delays.
