Hon Stuart Nash
Minister of Revenue
2 May 2019 MEDIA STATEMENT
One of the biggest IT projects ever undertaken in the state sector has successfully passed its latest hurdle with the
transition of more than 19.7 million taxpayer accounts from one Inland Revenue computer system to another.
Revenue Minister Stuart Nash is congratulating staff and the external agencies, including banks and ICT companies, who
worked on the project known as Business Transformation Release 3.
“We are committed to ensuring our tax system is fair. That also requires us to ensure it is administered fairly through
Inland Revenue’s own processes”, Mr Nash says.
“The department had to close its call centre and online presence over the Easter and ANZAC break to enable it to happen.
A lot could have gone wrong. But instead, everything appears to have gone right.
“Every single taxpayer account for Income Tax and Working for Families was migrated from the legacy computer system to
the new system, known as START. It involved a mind-boggling number of transactions and processes.
“The system went live on Friday and has been tested in the real-world environment over the past few days. For example,
this week it processed $33 million in Working for Families payments for 161,000 customers.
“The new system will continue to be tested in the coming weeks and extra staff have been brought in to handle customer
questions. It is still early days and there are likely to be bumps along the way. However, IR assures me it has plans in
place and will be ready to respond.
“The short-term inconvenience to customers while they get used to the new system is more than offset by the significance
of the changes. Every taxpayer affected will now have their account managed in a smarter, fairer and more efficient way.
“Too many people have been paying the wrong secondary tax. IR’s technology will now be smart enough to spot if someone
is overpaying tax and help them correct it with a tailored tax code. It will make a big difference for those with more
than one job or an irregular income.
“It also allows for automatic tax assessments. From late-May to mid-July, salary and wage earners will find out if they
have a refund owing or a bill to pay. About 1.65 million customers will be told they have a refund.
“If this year is anything like 2018, an estimated $860 million will be refunded straight into people’s bank accounts.
“Around 330,000 families receiving Working for Families support will receive more accurate payments during the year.
This means they get the assistance when they need it and have less chance of a debt to repay at the end of the year.
“All tax revenue is now administered in the new system, after GST, withholding taxes, fringe benefit taxes and others
were migrated in the past two years. Other systems administered by IR, including student loans, KiwiSaver and child
support, will be migrated in the next two years.
