For many of us, the proposed capital gains tax on the second home will be a hot topic, especially for those who invested in a second home years ago to secure their retirement.

I have two questions that you might be able to answer:

• If this tax is introduced, let's say by the first of January 2021, will it be applicable only for second homes bought from that date onwards, or will it be applicable to everybody who, in the past, bought a second home for investment and it has been in the family for, say, 30 years or more and now decides to sell?

• Is Mr Cullen adjusting the increase in value of your second home by the increase in value purely as a result of the yearly inflation?

I happened to bump into the Reserve Bank website where you can find an inflation calculator.

In 1996, I purchased a modest three-bedroom house in Napier for $200,000,
According to this calculator, based on inflation only, the house should now be worth $768,554, but it is not. The current median house price in Hawke's Bay is about $438,000.

So if I decide to sell this house, why should I pay a capital gain tax on the "profit" when in fact there is no profit at all?

Oh no, not bad news about the beloved family bach, scene of many a heart-warming gathering — which I assume is what you're writing about. But the new tax may not be as bad as you fear, or may not happen at all.

Although everyone in the Tax Working Group supports the idea of taxing rental-property gains, just eight of the 11 members support the wider package, which would cover second homes.

Given this lack of unanimity, the Government seems less likely to adopt all of the wider package. And even if it does, it has to be re-elected before the changes take effect.


Still, it's important that we all understand what's being proposed. So let's answer your two questions:

• The proposed tax would apply to all second homes, regardless of when they were bought. But the tax would be only on the gain made after what the working group is calling Valuation Day, on April 1, 2021.

• No, inflation wouldn't be used. People with taxable assets would have to get an assessment of their worth on Valuation Day. The taxable gain would be the rise in value since then.

That doesn't mean all valuations would be done on Valuation Day — an impossible task. You would have five years after that to get the valuation done, but with the value set at what it was in April 2021.

"The rules for Valuation Day should provide taxpayers a choice between simplicity and accuracy and provide different options for different types of assets," says the working group report.

For property, the options might include comparison with similar properties, perhaps using Quotable Value (QV) valuations, or recent ratings valuations (RVs).

The latter are "easily obtainable but may be inaccurate depending on when it was last updated. A choice between the RV before and after Valuation Day may be more accurate in some cases", says the report.

If you don't make a valuation, default rules would apply.


Oh, and don't give up on the Reserve Bank's inflation calculator. It's really useful in all sorts of situations. You can use it to work out the effects of general CPI inflation or inflation on food, clothing, housing, wages or transport.

You obviously used the housing calculation, but it's based on house prices throughout New Zealand. And, as we all know, there are huge regional variations in house price rises. But for many other calculations national figures are fine.

Gaining fairness

What's all the fuss about a capital gains tax? If you have to pay it, be thankful because you have made a capital gain and you can keep most of it.

I love your letter. It goes right to the heart of the issue about fairness — a word that appears no fewer than 54 times in the Tax Working Group's Final Report Volume 1.

One of the main reasons the group wants tax changes is that under the present system some income is taxed and some is not.

Also, our system is more "regressive" than in many other countries — our taxes and transfers (benefits and Working for Families) reduce income inequality less than in most OECD countries, as the graph shows.

What's more, the working group says, the power of taxes and transfers to reduce inequality in New Zealand has weakened over the past three decades.

Both effects — the lack of a capital gains tax and the regressive nature of our system — "weigh against the sense that New Zealanders are all making a fair contribution, and risk undermining the social capital that sustains public acceptance of the tax system and so our shared prosperity in the long term", says the report.

In other words, the more people think our system is unfair, the more they'll try to rip it off.

The working group adds that, internationally, capital gains taxes mainly affect the wealthiest people.

"In the United States, the richest 0.4 per cent of returns accounted for nearly 60 per cent of capital gains in 1998. In the United Kingdom, less than 0.1 per cent of returns accounted for 60 per cent of reported capital gains in 1997-98 and paid more than 75 per cent of all capital gains taxes.

"Capital gains are an important source of income for the wealthy but much less so for the middle class."

So, taxing those gains would help reduce income inequality.

Spreading the risk

We are mindful that we are in the very fortunate position of having two good jobs and property in two areas of New Zealand. We are both in our mid-40s with three school-aged children. We are all in KiwiSaver.

We have a rental in Auckland (carries all our debt) and live in our own place in Tauranga.

Would we be better off to sell the rental? We have just read your latest book, Rich Enough — A Laid-Back Guide for Every Kiwi, and the big takeaway was diversification. We are aware we have a lot of money tied up in "housing".

We contribute about $700 a week to the mortgage over and above the rent.

If we sell, we are likely to have about $400,000 surplus and be mortgage-free.

Would we be better off investing the surplus plus the savings off not having a rental (mortgage and other costs of a second house) in some other investment?

The proposed ring-fencing of tax losses will also increase the cost of having the rental.

Are these the types of questions we could discuss with a financial adviser, or is their role to advise where to invest funds if we decided to sell?

As I've said a few times lately, nobody knows whether you will end up better off financially keeping the rental or investing in, say, a share fund.

Both are risky but usually do well over the long term. But diversification is indeed relevant. It's riskier to have all your savings in housing.

Your comment about the proposed ring-fencing of losses on your rental may actually be out of date. Under that proposal, which is part of a tax bill before Parliament, your losses could be used only to reduce tax on future rental income, not on other income such as salaries.

However, if the Government starts taxing capital gains on rentals, ring-fencing might not be introduced, or might be cancelled.

"The case for residential rental loss ring-fencing is reduced if the taxation of capital gains is extended to cover residential rental investment property," says the Tax Working Group.

"Gains will be taxed when properties are sold, although there will still be some timing benefits for landlords if losses are not ring-fenced because gains are taxed only on realisation." Realisation basically means sale.

"To the extent the taxation of capital gains could put upward pressure on rents, the removal of ring-fencing on residential rental property may aid in limiting potential rent increases."

Of course, having to pay capital gains tax on gains on your property after Valuation Day might well be a bigger minus than ring-fencing. It would all depend on your circumstances.

And, yes, these are questions that some financial advisers should be able to help you with. First, look for an adviser who charges you fees and takes no commissions from any providers of financial products. They are much more likely to put your interests first.

On the Advisers page of my website,, I explain this more, and at the bottom is a list of such advisers.

Within that list, I would look for advisers who charge by the hour, rather than those who charge a percentage of the money you have invested. The ones who charge hourly are more likely to be unbiased in helping you decide whether to keep your rental.

Check out the advisers' websites for how they charge, or contact them and ask them.

Colour coding

Your recent item on the Smart Investor tool pinged an idea I would like your thoughts on.

Assuming the Ministry for Business, Innovation and Employment, the Financial Markets Authority and the Commission for Financial Capability are truly unbiased, how about the Smart Investor tool they created indicating the social value of companies by the colour of the online font?

• Firms with good reason to avoid investing in (for example, nuclear waste, arms and weapons, favouring murderous regimes) in a red font.
• Firms involved in smoking and gambling, firms that choose to make and/or sell stuff but do not consider the long-term social and personal damage caused, in orange.
• Firms demonstrating high ecological values in their practices or products, being openly generous to public organisations, and so on, in green.

Of course, all choices of font colour should enhance the neutrality of the three above organisations that publish the tool online. But the actual financial performance of the various investments would be separated from the company's approach.

The font colour could give a general background signal without making a written comment, and the investor would still make their final choices, but hopefully in a more informed way.

At first glance colouring of fonts looks a bit trite or light-handed, but the closer one looks the more potent the underlying message of the colour could be in helping us select investments.

Thumbs up or down?

Tom Hartmann's thumbs are up! He's managing editor at the Commission for Financial Capability and one of the main developers of Smart Investor.

"People not only want to invest effectively, they also want to invest ethically," he says.

"Smart Investor, at the moment, focuses on people getting ahead financially. This was appropriate given it was developed by a ministry aimed at improving the rules around investing (MBIE), a watchdog keeping investors safe (FMA), and an agency focused on lifting people's long-term financial wellbeing (CFFC).

"There has been so much progress in the field of ethical investing, and should this become a Government priority (it will take funding), we can easily imagine a collaboration with an expert organisation like Responsible Investment Association Australasia that would upgrade the tool in ways like you're describing. Bring it on!"
