Party Strategies and Income Tax



Our political parties are always conflicted between their desires to survive and promote a philosophy and set of policies, and their wish to govern or at least participate in government. The former is their reason for being; the latter is their opportunity to make a difference through government.

The Maori Party is in danger of not surviving, because it pursued participation ahead of purity. (For people in the political centre, the Maori Party is an extremely good party-vote option this year. Given that the Maori Party is likely to gain just one electorate, centrist voters can bring in Maori Party list MPs, and, by doing this, may see the Maori Party displace New Zealand First as the ‘king-maker’ party in the middle.)

The Green Party remains strong and saintly because it has avoided participation in government, and, by placing itself to the left of Labour, will probably continue on this government-avoidance path. We may see a repeat of 2005, when New Zealand First shut the Greens out.

The Labour Party looks unlikely to score more than 25% on the party vote. This hides a possible cunning strategy that may turn a low party into victory for the left. As far as I can tell, this year Labour is placing much greater emphasis than National on the electorate vote. The cunning strategy would be for Labour to bleed party votes to Green or Internet Mana, while pulling out all stops in the local electoral contests.

(The electorate vote is generally much like a Mayoral contest. Voters understand this, though journalists by and large do not. Many cities have Mayors with different political persuasions from the parties that are favoured in general elections. And many electorates are represented by MPs of a party that did not win most party votes in that electorate. That was indeed true of my own New Lynn electorate in 2011.)

Looking at iPredict a few days ago, I found 28 electorates that Labour candidates are likely (45% chance or better) to win. Then there are other electorates which Labour can win, such as New Plymouth, Rotorua and Maungakiekie. If Labour get just 22% of the vote (as National got in 2002), then Labour could have several overhang seats and no list MPs. The second bonus for Labour, under this scenario, would be the loss of Mr Miser (David Parker). They would be well placed to rethink their economic policies, and they might even be in a position to implement their rethought policies.

Tax Strategies

In the following I will suggest tax strategies for the principal parties on the right and left; strategies that emphasise the middle ground of participation through compromise. Whenever a party participates in government it will inevitably have to make choices that upset its members for whom philosophical purity is more important than influence. One policy direction that discomforts the parties of the left is cutting taxes.

I suggest here a good, deceptively simple, and potentially very popular income tax policy for the left. But before that, I note National’s situation, and what National can do on the income tax front if it wants to be returned to government.


National Party

For the National Party being in government generally wins out over philosophical purism. Nevertheless, the tension is always there. It’s the party of privilege and property. It attracts voters without privilege or property through a mixture of aspirational politics – privilege (‘success’) and property are presented as something anyone can achieve – and divide and rule politics. The cultivated nuance is that it’s the non‑aspirational ‘losers’ on the left who hold back those battlers with little but their aspiration.

Parties of privilege are not the natural parties of government in a democracy. By definition, only a minority can attain privilege. So parties on the right always need to ensure that centre-right voters always vote, and that their votes are not wasted on some party that will not qualify for entry under the prevailing MMP qualifying rules. National nearly blew it last time, allowing five percent of ‘right’ votes to be wasted on the Conservatives. This time, thanks to ‘dirty politics’, National can probably count on Conservative votes counting. National remains in the box seat. But the suspicion remains that, once again, the rich are intended beneficiaries of National’s income tax policies.

National’s pitch for the centre is its emerging promise to cut taxes to low-middle income earners; to give something back to the underpaid battlers whose support it depends on. Indeed it’s a good strategy, though one that could be bungled. It recognises that many of these people lead insecure and exploited lives. They are not getting a fair return on their public equity; on their stake in New Zealand Inc.

There are two credibility problems for National. First, when National says they will reduce the taxes of low-middle income recipients, does it mean only low-middle income workers? Or does it mean low-middle income earners as well as high income earners. While John Key and Bill English will not want voters to think that they mean the latter (‘as well as’) option, the structure of our tax scales makes it tricky to implement the former (‘only’ low-middle income) option.

Fortunately, I can do tricky; tricky as in ‘good at arithmetic’. The way to achieve the ‘only low-middle-income option’ is to cut taxes at the bottom end of the scale while simultaneously increasing them elsewhere in the scale. Here is what National must do if it to keep faith with those to whom it has dangled the tax-cut carrot.

Actually I can suggest three options. All give tax cuts in the range of $10 to $30 per week to persons earning between $5,000 and $50,000 per year, while giving neither an increase nor a decrease to persons earning over $70,000.

Option 1. Remove the bottom 10.5% tax rate; make it zero. Simultaneously extend the 33% tax bracket down to a threshold of $42,775. People earning between $14,000 and $42,775 would get a tax cut of $28.27 per week. Someone on $60,000 per year would get a cut of $5.77 per week.

Option 2. Remove the bottom 10.5% tax rate; make it zero. Simultaneously raise the 17.5% tax rate to 19.88%. People earning $14,000 would get a tax cut of $28.27 per week. Someone on $60,000 per year would get a cut of $5.78 per week. (All persons earning $70,000 or more would gain precisely 80c per year!)

Option 3. Remove the bottom 10.5% tax rate; make it zero. Simultaneously remove the 30% tax bracket, reducing the 33% threshold from $70,000 to $48,000; and reduce the first threshold from $14,000 to $9,370. People earning close to $10,000 would get a tax cut of almost $19 per week. Most people would get a cut of $12.69 per week. (All persons earning $70,000 or more would pay 1c more each fortnight.)

In noting that one of the major aims of the National Party is to transition people from welfare to work, the single most important policy to achieve this end is to remove almost all taxation from casual primary employment and part-time employment. My suggestions achieve this.


Labour and Green Parties

I heard on Radio New Zealand yesterday morning that Russel Norman thinks our fiscal priority is to pay down public debt. It is sad to hear that the Greens are competing with Labour to be the party of austerity. In general the two parties seem closely aligned on income tax, promising to tax the top five percent a little bit more in return for some measures to reduce child poverty and school class sizes. They are not really offering any hip-pocket incentives to those voters in the middle.

This preference for principle over participation – a rather dubious principle of private and public parsimony – suggests that their only possible route to power is some major blunder on the right, or at least the hope that Winston Peters will maintain his present distaste for National.

On debt reduction, the most fiscally sound principle is not to repay debt; it is to increase public debt in the medium term at the same rate that the economy is growing. Public debt should only be paid down when the economy is really booming; indeed when the private sector is taking on debt. (Also, public saving must coincide with private dis-saving). As a rule of thumb, no government should repay debt while the unemployment rate is over four percent. And governments should be running deficits if the unemployment rate is above five percent. Across the economic cycle, governments should be running deficits about two-thirds of the time.

The Labour and Green Parties should be aiming to raise taxes overall, while paying tax cuts to the critically important low-middle income households. In short they should adopt, for this election, one of the same tax policies that I have suggested for National (say the conservative Option 3), but with one difference. Labour would raise the 33% rate to 36%, and the Greens would raise the 33% rate to 40%.

This (at Labour’s proposed 36% top rate) would mean everyone earning less than $92,000 per year getting a tax cut and everyone earning more than $92,000 getting a tax increase. By far the majority of taxpayers would receive the maximum $12.69 per week tax reduction. Someone on $150,000 would pay $33.47 per week more in income tax, hardly a wallet-breaker. Revenue lost on the $12.69 tax cut would largely be made up in revenue gained on the reduced threshold for the 36% rate, and a higher trust rate (36%).

For the Green Party, if they follow the same (Option 3) approach, but levy 40% on marginal income over $70,000, there will once again be a general tax cut of $12.69 per week. Everyone earning less than $79,425 would get a tax cut of $12.69 or less. Everyone earning more than $79,425 would get a tax increase. Someone on $150,000 would pay $95.00 per week more, substantial but affordable.


Income Tax Reform

The above suggestions could be political winners in 2014 for whichever of the abovementioned parties takes them up. But they are not in themselves tax reforms. Rather they are adjustments to the present tax scale that give small tax cuts only to people on low-middle incomes, and give no-change or tax increases to higher income recipients.

Actual tax reform requires a conversation on more sustainable ways to account for taxes and benefits; and to show how it is possible to simultaneously increase productivity, decrease labour supply and decrease inequality. Technically it is very easy to do. The obstacles are mainly conceptual inertia and the widespread innumeracy of people who identify with the left of politics.



  1. Really interesting Keith. I am one of those who identify with the left but also suffer from severe innumeracy (despite a higher education). I would love to hear your ideas for actual tax reform.

    • Thanks. For my ideas for actual tax reform, I suggest going to my April postings “Universal Basic Income?” and “Universal Basic Income? Reprise”.

      By the way, in this posting I have underspecified my proposal for the Labour and Green Parties. My proposal for Labour was to have 4 tax rates (0%, 17.5%, 30%, and 36%) with thresholds at $9,370, $48,000, and $70,000. My proposal for the Greens was the same as that for Labour, but with the 36% rate becoming 40%.


      • With reference to my earlier articles on “Universal Basic Income?”, I noted that the present income tax system contains embedded within it a public equity benefit of $9,080 per year that is paid as of right to all persons earning over $70,000, and in more convoluted ways to most other New Zealand adults.

        With respect to the tax policies I have advocated here:

        For National my suggestion translates to a public equity benefit of $9,080 per year paid as of right to all persons earning over $48,000.

        For Labour my suggestion translates to a public equity benefit of $11,840 per year paid as of right to all persons earning over $70,000; with at least $10,520 payable to all persons earning over $48,000.

        For Green my suggestion translates to a public equity benefit of $14,640 per year paid as of right to all persons earning over $70,000; with at least $12,440 payable to all persons earning over $48,000.

        At its core, the suggested National tax scale can easily translate, through Basic Income Flat Tax reform, to a flat tax rate of 33% and a basic income of $9,080. The suggested Labour tax scale can easily translate, through such reform, to a flat tax rate of 36% and a basic income of $11,840. And the suggested Green tax scale can easily translate to a flat tax rate of 40% and a basic income of $14,640.

        This is the way elections should be fought; around a core of competing sets of equally affordable tax-benefit trade-offs.

        What is affordable would be an FT-BI combination that is consistent with a stable (across the economic cycle) forecast public-debt to GDP ratio. Our present ratio is about right; not too big, not too small.

        Each election National would propose a lowish tax rate and a lowish public equity dividend. Labour would propose a moderate tax rate and a moderate public equity dividend. Green would propose a higher tax rate and a higher public equity dividend.

        Over time, as labour productivity increases, all responsible parties should propose increases in both the public equity dividend and the tax rate. This increase in return on public equity would be the country’s growth dividend.

  2. Couldn’t finish reading this. Calling the Greens and Labour parties of austerity is ridiculous. Further, claiming that Winston can shut out the Greens even though no legislation could pass without Green votes shows some pretty shallow analysis. Next.

    • Unfortunately, both Labour and the Greens ARE fundamentally parties of austerity. That is not to say they are as hardline as National, however, you only need to listen to Cunliffe’s response to questions re: asset sales buy-backs or “where is the money going to come from?” to witness it’s underlying presence.

  3. Just heard on the radio this morning. New vehicle sales are booming! Just what people working 40-60 hours a week, six or seven days a week paying more than half their income each week to rent a damp, crappy house need to know. Shows who is doing best out of National’s “rockstar” economy – the few rockstars and not the many fans.

    • Mike, we have an economy in which those who work hard get ahead. Those who don’t, don’t. There is ample work, and one of the highest minimum wages in the OECD. If people are renting damp, crappy homes, they should move. There are plenty available that aren’t.

    • I think your assumptions here are wrong. I seem to remember seeing a similar reaction from the public in the past. The reason seems to be this. People save all their bikkies to buy their first house. In the meantime they put off buying a new car.
      After a few years they discover that, because of house prices rising faster than their savings, the dream of buying a new house is unachievable so the dream is abandoned. This leaves them with money in the bank and a shabby car, so they bolster their shattered self-esteem by buying a new car. I would’nt be at all surprised if there is a boom in overseas holidays next summer as well.

  4. Great article. Russel Norman’s views on fiscal policy, especially the importance of paying off debt, have probably just convinced me to vote Mana. The Greens have a lot of great policy, but as long as Norman is going for the Milton Friedman memorial prize, they won’t be able to act on most of it.

    • It is certainly disappointing to hear that the Greens are going for neo-liberal monetary policies (of course Labour would). I thought that philosophy was killed by the recent disclosures of the Bank of England about how the Commercial Banks create our money supply from nothing every time they make a loan.
      This revelation means that there is now no reason why the Reserve Bank should not create our money supply instead, as the Democrats for Social Credit have long claimed, and PositiveMoneyUK have more recently asserted. That would mean that the Government would never have to go into debt at all. I see that the Internet Mana Party vote is sliding recently. If they were to adopt that policy perhaps it would give them the boost they need.

  5. Programmes like Working for Families are ways of giving tax cuts to low income families. The most targeted tax cut that could be delivered that would only benefit the very poorest families and not require higher taxes nay where else is to add the In Work Tax Credit to the first child Family Tax Credit. It would cost $450m per annum and would be the most sensible fair practical way of delivering a tax cut in today’s unequal society with rampant child and family poverty .
    But can we expect National to grasp that?

  6. Hi Keith. I am a centre right voter, but your analysis is very sound. I would have no problem continuing to pay the same tax I do now, and would prefer near future cuts to go to low income people.

    One of the challenges we have is the fact that low income families pay little or no net income tax because of WFF. Would we be better moving away from such reliance on WFF via a high tax free threshold?

  7. Just because the Greens and Labour want to pay off debt doesn’t make them neo-liberal, as some contributors here are suggesting. We have already seen with this National government that high debt means less control over your sovereign rights. Rio Tinto, Warner Brothers and now the US government itself is using our crippling overseas debts to put political pressure on us and of course the great National lap dog will go belly up and do whatever its masters want. If you think that adding more billions of dollars of debt will make this situation better then you are deluding yourselves.
