Yes, there are millionaires who pay no tax, but crimping deductions mightn't help

For some people tax time will result in no tax paid this year, and if past years are anything to go by, about 50 of them will be millionaires.

Not mere millionaires, but millionaires earning more than A$1 million per year.

For some of these 50 or so very high earners, managing tax will be expensive. The two dozen or so that typically claim deductions for the “cost of managing tax affairs” claim an average of about $1.7 million each.

It might have been with this in mind that during last year’s election campaign Labor promised to cap the size of the deduction people could claim for “managing tax affairs”. The proposed cap was $3,000.

Tax agents would still be able to charge more than $3,000 – a lot more if they want to, even an additional million or more – but their clients would only be able to deduct $3,000 of it from their income when submitting their tax return.

Labor wanted to cap deductions

The rationale was straightforward: if people are claiming over $1 million in deductions on money spent managing their taxes, then putting a ceiling on those deductions ought to stop it.

Not so fast.

Often in tax we plug holes quickly rather than stepping back and looking at the whole system and its interactions. And then we have to plug another one.

The question to ask first is whether capping this individual line item would prevent or move the leakage.

We went to the source by conducting a nationwide survey of Australia’s most senior tax professionals to glean their perspectives.

Our findings reflect the views of people who, to paraphrase Mandy Rice Davies, “would say that, wouldn’t they”.

It might not have worked

Nonetheless, the detail of what they told us was surprising.

Here’s what they said.

• Most of the targets would be unaffected. They would be able to switch their deductions into associated corporate entities. This interchangeability of personal and corporate tax deductions highlights the importance of considering the system as a whole.

• Because of this it might, counter-intuitively, have the opposite effect to what was intended, creating a saturation where the truly wealthy could escape the cap, but those of lesser means could not.

• A better solution would be for the tax office to conduct more tax audits. Studies suggest the decisions of high wealth individuals to engage in aggressive tax planning practices are strongly influenced by the probability of being selected for audit.

• There are definitional ambiguities in relation to the subcomponents of the deduction that make it hard to work out what is going on. Sometimes “litigation” includes tax planning, other times it does not. “Other” is a grab bag that can include software costs, travel costs and reference material. It would help if the tax office provided guidance.

• High wealth individuals often employ tax advisers to cope with complexity and uncertainty of the tax system rather than to reduce tax.

As we said, you are welcome to consider the possibility that the observations of the tax professionals are self-serving, but their overwhelming embrace of more tax audits and their pleas for the tax law to be easier to understand also suggest a keenness to ensure that taxpayers do the right thing.

Labor’s proposal to cap the deduction for the cost of managing tax affairs at $3,000 (when for most people the deduction is closer to $300) was understandable, although it might not have worked as intended.

It was a reminder of the oft-quoted maxim that for every problem there is a solution that is simple, neat – and wrong.
