This weekend’s New Zealand general election offers some choice in GST policy.
So, if you’re a GST geek like me you might be swayed by what the different parties intend doing about GST.
Here’s what I’ve been able to find out about some of the main parties’ GST policies:
Labour Party – no change to base or rates. Committed to simplifying compliance and supports “one hour, one return, one payment” principle for monthly GST and income tax compliance.
Green Party – no change to base or rates. Propose extra ecological taxes but will leave detail to a commission. Also, propose financial transaction tax. [comment – subject to seeing the detail, the existing GST system could be one way of achieving these new tax imposts].
National Party – no change to base or rates.
Mana Party – propose abolition of GST and replace with “Hone Heke Tax” on financial speculation.
Maori Party – will revisit removing GST on healthy food (fruit and veges) and also increasing GST on sugary drinks.
I couldn’t find any detail from other parties. If anyone knows any more feel free to comment.
Cheers and happy voting on Saturday Kiwis
A NZ Herald/Digi Polls finds support for fat taxes: http://www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=11298134
To have any real behavioural impact a fat tax needs to be at least 20%: https://iainblakeley.com/tag/fat-tax/
Removing GST from food is back on the political agenda thanks to Winston Peters’ announcement yesterday.
Recent calls for GST free food have focussed on the health aspects. This doesn’t seem to be a prime motivator for NZ First but it does appear the policy would not extend to removing GST from fizzy drinks and some other sugary foods.
NZ First’s stated objective is to lower the cost of food for low income households.
Voters need more information on this. Overseas research I’ve seen suggests removing tax on food has an immediate downward impact on prices but it is shortlived. Within several months prices tend to move back close to the levels they were at when the tax applied.
Also, those who benefit most from removing GST on food are those who spend the most, a bigger subsidy for high income households.
Then there are the compliance complexities of different GST rates for different types of food. The overall costs to government (taxpayers) of collecting GST will go up. GST will become less efficient and tax advisors will be busier.
Overall I think there are probably more effective ways to provide relief for low income households but it’s a good debate to have given New Zealand’s comparatively high GST rate on food.
“Unhealthy diets are now a greater threat to global health than tobacco” – said UN Investigator Professor Olivier de Schutter to the World Health Organisation annual summit on 19 May.
Professor De Schutter’s suggested solution is a global pact to tackle obesity similar to the UN convention on tobacco control in 2005. The accord should include taxes on unhealthy products, regulation of food high in saturated fats, salt and sugar and restricting junk food advertising.
This debate has been around for a while and doesn’t look like going away any time soon, particularly in NZ during an election year.
Similar calls are made for environmental taxes which are also about discouraging certain consumption or behaviour.
In New Zealand recently the debate on food taxes culminated in a Bill before Parliament from the Maori Party to remove GST on fresh fruit and vegetables, i.e. “subsidising” healthy foods as opposed to taxing the unhealthy, admittedly because a focus of the policy behind the Bill was the cost of food. The Bill did not get Parliament’s support.
It seems to me the “subsidy” versus “penalty” debate is now pretty settled. Plenty of studies have shown subsidising healthy foods benefit most those who already consume the greater proportions of healthy food (which we are told are higher income households). So, those who least need to change their eating behaviour receive the greatest subsidies.
Another issue with healthy food subsidies is they aren’t as effective in changing consumer behaviour. The money saved by high consumers of unhealthy foods tends to be spent on more unhealthy food or other stuff rather than more healthy food, the opposite of what is sought. In part this is because the amounts they save from the subsidy are too small to make a big difference.
Increasing taxes on unhealthy products can be effective. Tobacco is a good example. Various trials with taxes on sugary drinks in the US and Ireland and a 2013 study in Norway indicate small tax increases are hardly worth doing. Real behavioural change comes when the tax is at least 20%.
The big problem with extra taxes on food is their regressive impact, i.e low income households end up paying a higher proportion of their income on the tax than better off households. Supporters of these taxes will argue this is exactly why they can be so effective (i.e. the tobacco example).
Reportedly lower income households are more highly represented in poor health statistics. One reason we’re told is that unhealthy food per calorie is cheaper than healthy alternatives and, therefore, low income households tend to consume proportionately more unhealthy food resulting in poorer health outcomes. Thus, supporters of fat taxes would argue they may be “regressive” but their outcomes are “progressive”.
If countries follow Professor De Schutter’s advice and those arguing for fat taxes New Zealand could well find itself grappling with how best to tax unhealthy food.
The tobacco model would suggest some sort of excise tax.
Personally I think GST has to be the preferred mechanism for implementing this sort of policy. Sure it flies in the face of our “pure” GST system, of which we have every right to be very proud. It’s the most efficient VAT/GST in the world. However, it just makes sense to me. Why add another tax to businesses and the IRD when they already have a collection system that they’re quite used to?
Yes, there’s complexity with having a higher GST rate for certain products but that’s going to arise whatever mechanism is used for any fat tax. The legislation is going to have to be very clear on what’s in and what isn’t. As long as that part is got right the added complexity for most businesses will be no more than businesses all over the world already deal with.
The problems with differential rates in VAT/GST systems arise mainly from definitional issues. What items are caught by the higher rate? Any legislation taxing unhealthy foods would have to find a clear, scientific way for identifying those items. Provided that can be done I think the best way to impose any such tax is to have a higher GST rate for those items.
