The New Zealand Tax Podcast – Coleman calls for a better KiwiSaver, PM gets it wrong on KiwiSaver, privacy busted on IRD tax deduction Notices, tip-off & audits

Last week I joined Gareth Vaughan of interest.co.nz for a joint podcast with Andrew Coleman. He's a New Zealand economist who has worked in academia and for the government, including Reserve Bank, Treasury and the Productivity Commission. In the last few months, he’s written a 13 part series for Interest looking at how we currently fund New Zealand Superannuation and what alternatives we should be considering.

Why we’re talking about more tax – the rising cost of New Zealand Superannuation

As I've mentioned previously, part of what's driving the debate around whether New Zealand should have a capital gains tax is when you consider the government’s long term fiscal position the conclusion you reach is that something radical will have to happen: either benefits will have to be reduced significantly, or taxes will have to be increased. If we're increasing taxes, how are we going to go about that? That, by the way, is the subject of Inland Revenue’s long-term insights briefing consultation on which is going on at the moment.

Coleman has written extensively about the issue of funding New Zealand Superannuation and in the podcast he went through the issues behind why he wrote the series and what alternatives he proposes. It was very informative, and I highly recommend listening to the full podcast. Here are a few key takeaways.

New Zealand’s unique approach to funding superannuation

Firstly, the way New Zealand currently funds New Zealand Superannuation is very unique in that it is entirely funded out of current taxation. That means the current cost of New Zealand Superannuation, over $20 billion a year before tax, is being paid out of current taxation. This is unusual by world standards, because most other countries in the OECD adopt some form of Social Security tax to pay for their public superannuation. In Britain they have National Insurance Contributions, in America, they have Social Security. Throughout most of the EU you will see Social Security taxes in place.  Apart from us, only Denmark in the OECD has no Social Security taxes. Other countries use social security taxes to pre-fund superannuation; people pay social security taxes which are then drawn down when they reach retirement age. We fund everything out of current taxation.

Allied to that, and a matter that makes our tax system unique, is that most other jurisdictions operate what's called an exempt, exempt tax (EET) approach to private retirement savings. That is a person gets some form of tax deduction for making a contribution to a private superannuation savings scheme. The superannuation schemes are not taxed, but when you withdraw funds on retirement age you pay tax at that point. On the other hand, since 1989 we have adopted the complete opposite approach (TTE). We don't give a deduction for contributions to superannuation schemes such as Kiwisaver, which are subject to the ordinary rules. However, withdrawals are tax exempt.

Point of order Prime Minister…

Just as an aside, I note that one of the Prime Minister’s comebacks to questions around capital gains tax was that if introduced it would apply to KiwiSaver. (Actually, when the last Tax Working Group proposed a CGT, they didn’t actually seem to think to go there). The PM’s comment glossed over the fact that KiwiSaver funds are subject to tax. If they've invested in bonds, these are subject to the foreign financial arrangement regime. If they've invested in overseas stocks, those are taxed under the Foreign Investment Fund which because the 5% fair dividend rate automatically applies, is a quasi-wealth tax.

Time for social security taxes?

That point of order aside, Coleman’s key point remains that our treatment of private superannuation schemes and funding of public superannuation is quite unique by world standards. So how are we going to meet the growing cost of superannuation? He suggested that maybe we should look seriously at Social Security taxes.

A Capital Gains Tax won’t be enough

Gareth and I raised the question of alternative taxes, such as a capital gains tax and Coleman made the point that the likely cost of New Zealand Superannuation scheme is going to rise towards somewhere around 8-9% of GDP. Hence the need to be thinking about how to fund that cost. Capital gains taxes don't generally raise that much, typically, somewhere between one and two percent of GDP. That still leaves a funding gap of between 6-8 percent of GDP. It's very doubtful a wealth tax, by the way, would make that gap up. In his view, the inexorable conclusion is that Social Security taxes are going to be needed to fill the gap.

How the 1989 changes helped distort the housing market

We also had a very interesting discussion about how the changes in 1989, which by removing the incentives for private savings, drove investment into residential property. He published his research on the matter in 2017, just at the same time that myself and the Honourable Deborah Russell, published Tax and Fairness. Separately we had reached the same conclusion, that the 1989 changes to the savings regime had driven people to start over-investing in housing.

Time for KiwiSaver 2.1

Coleman calls his answer to funding New Zealand Superannuation KiwiSaver 2.1 It would be a compulsory savings regime, but it would be for younger taxpayers, basically those under the age of 40 who were not old enough to vote back in 1997, when a referendum on a question of a compulsory superannuation savings scheme was overwhelmingly rejected.

Coleman’s argument is that younger taxpayers are currently funding what they want and need, such as health, education and transport. But they're also having to fund the superannuation of older taxpayers, who voted for the current system which benefits them. KiwiSaver 2.1 as a compulsory superannuation savings scheme would be a transition to a fairer system which would include some form of social security tax. The idea would be to be gradually building up savings in a similar way to Australia, which, although it doesn't have significant social security taxes, does have a compulsory savings scheme. There would be this transitional period, as the older workforce aged out, but all new younger workers would be part of the new KiwiSaver 2.1.

Taxing older, wealthier superannuitants

As part of the transition Coleman sees it requiring more taxes from older persons, which is where our discussion got to talking about capital gains taxes and wealth taxes. He's not a particularly big fan of wealth taxes. But he sees a capital gains tax having an efficiency aspect to it, which means it should be part of the tax system.

Incidentally, one suggestion I have seen about taxing superannuitants involves applying a separate tax rate to persons receiving New Zealand Superannuation. This would be a way of clawing back payments from those who have other means without going down the route of the deeply unpopular means testing that happened in the early 1990s.

I thoroughly recommend listening to the podcast. Coleman’s analysis highlights the need to keep in context why we're having this discussion about capital gains and wealth taxes and that's to do with everyone realising that we have to address the rising cost of funding New Zealand Superannuation and related healthcare costs for the elderly.  These issues are not going to go away because the demographics are inexorable, contrary to what politicians might hope as they repeatedly kick the can down the road.

Tax deduction notices

Moving on, Inland Revenue makes great use of tax deduction notices as a debt collection tool.  These enable it to require a third party to make deductions from payments due to a taxpayer with an outstanding tax liability. The power is contained in section 157 of the Tax Administration Act 1994, or related provisions of the Child Support and Student Loans Acts. I once saw a notice where a supplier to someone with tax debt was told to withhold 100% of any payment that was going to be made to the person in default.

Inland Revenue typically issues thousands of deduction notices each year.

^{(Figures obtained under the Official Information Act)}

Inland Revenue has just issued a draft standard practice statement providing guidance on how it would use these notices.

I think it's appropriate Inland Revenue has the power to issue deduction notices. My concern, however, is I've seen them issued for under $1,000 of tax debt which in my view is an inappropriate use for what is a fairly small sum of tax debt under $1,000. When a deduction notice is issued to an employer in such circumstances this essentially notifies the employer that the relevant employee is behind on their taxes.

Are these notices breaches of privacy?

In my view, a deduction notice in this situation represents a breach of privacy and employers really do not need to know about relatively small sums of tax debt owed by an employee. Instead, and I will propose this in my submission on the draft, I believe Inland Revenue should make greater use of tailored tax codes to collect the unpaid tax from an employee. The employer still has the responsibility for deducting the tax through PAYE but now all they know is the tax code has changed. They don't know the reasons why. This preserves the privacy of the person who has been the subject of the tax deduction.

I think this is important. I discussed this issue with a previous Privacy Commissioner, and he was of the view that, yes, it seemed like a breach of privacy. But as he noted, he couldn't really do much about it because Inland Revenue had the legislative power to issue the notices. Still just because Inland Revenue can doesn't mean it should, and I think there are opportunities for improving matters. Looking at the UK, it’s common practice for HM Revenue & Customs to use adjusted PAYE codes to collect arrears of tax. Submissions are open until 15th November.

How many anonymous tip-offs does Inland Revenue typically receive each year?

Across the ditch the Australian Tax Office (ATO) revealed this week that in the past five years it has received over 250,000 tip offs about potential tax evasion. According to ATO assistant commissioner Tony Golding "We get on average over 3500 tip-offs a month from people who know or suspect tax evasion or shadow economy behaviour.” The ATO believes there is about A$16 billion in stolen, unpaid tax each year.

By comparison, according to Inland Revenue it receives about 7,000 anonymous tip-offs each year. These are important sources of information even if sometimes the tip-offs are malicious and stem from toxic relationship or business breakdowns or partnership breakdowns. Regardless of this issue Inland Revenue will follow up (the ATO says 90% of tip-offs lead to further investigation.

How many audits is Inland Revenue undertaking?

On the issue of audits and my thanks to regular listener and reader, Robyn Walker of Deloitte for reminding me, Inland Revenue publishes Official Information Act responses and there are often some very interesting releases. One of the latest OIAs relates to the number of audit cases carried out on businesses between 2019 and 2023.

It’s interesting to see the impact of Covid and the quite marked drop-off in audits for those employing fewer than 50 employees.

There's also data on the number of shortfall penalties applied as a result of audit. Now shortfall penalties enable Inland Revenue to impose penalties of up to 150% of the tax involved where tax evasion has happened although the more common range of penalties is 20%.  Again, the somewhat sparse data makes for interesting reading.

That's all for this week. Next week, we'll be taking a deep dive into Inland Revenue with a look at its annual report.
