Proposed CGT Changes: Who Would Really Bear the Cost?

Atomic Business Advisers | TCs 2Cents

There has been plenty of discussion leading into the Federal Budget about possible changes to the capital gains tax regime, particularly the CGT discount.

At the time of writing, this is not legislation and it is not law.

It is based on commentary, leaks and ideas being floated before the Budget. That is not unusual. Governments often test ideas publicly before deciding how far to take them.

My concern is whether changes aimed at “the wealthy” may, in practice, land harder on ordinary Australians who simply have fewer options.

The family that upgraded

Take a fairly normal Australian family.

They buy a modest first home or unit.

A few years later:

  • their family grows;
  • their income improves;
  • they move into a larger home;
  • the original property becomes a rental.

That is not some grand property empire.

It is just a family gradually improving its position.

At some point, they may need to sell that first property to:

  • reduce debt;
  • fund another move;
  • cover family costs;
  • improve cash flow;
  • simplify things approaching retirement.

That is when capital gains tax becomes relevant.

If the CGT discount were reduced, or the tax treatment became less favourable, that family could end up paying more tax simply because they needed to sell.

The mum and dad investor

Now consider someone who owns one investment property.

Maybe they bought it years ago as part of a long-term retirement plan.

Owning a rental property does not automatically mean someone is wealthy.

Plenty of property investors are ordinary employees, small business owners and families who have slowly built an asset over many years.

Eventually, that property may need to be sold.

An estate is a good example.

When someone passes away, beneficiaries may decide the practical option is to sell the property and divide the proceeds.

The person who needs to sell is the one who ultimately brings the capital gain into play.

Wealth creates options

Now take the other end of the spectrum.

Someone may have built a substantial property portfolio over several decades.

They could have:

  • five or ten properties;
  • significant unrealised gains;
  • relatively low debt;
  • strong rental income;
  • positively geared properties.

Do they need to sell?

Probably not.

They may be able to keep holding, refinance, or eventually pass assets through an estate without immediately turning everything into cash.

Their beneficiaries may also have more flexibility.

That matters.

Generally speaking, CGT becomes relevant when a CGT event occurs, most commonly when an asset is sold.

So someone who can delay a sale may also be able to delay the tax consequences.

The people with fewer options often pay first

This is the part of the debate that gets overlooked.

A tax change may be presented as targeting wealth, but wealth itself creates options.

Someone with substantial assets and cash flow may be able to:

  • wait;
  • refinance;
  • retain assets;
  • restructure;
  • plan around a future sale.

Someone with one rental property may simply need the money.

That creates an uncomfortable possibility:

the people with the greatest flexibility may defer the tax, while those with the least flexibility pay it first.

Is this really a housing affordability measure?

If the purpose of changing the CGT discount is to improve housing affordability, then that is how it should be judged.

The key question is whether increasing the tax cost of selling an investment property actually improves housing supply or affordability.

I am not convinced that it automatically does.

In fact, a higher tax cost on sale may encourage some owners to hold properties for longer.

That does not necessarily make the policy wrong.

It simply means the issue is more complicated than saying:

“investors pay more tax, therefore housing becomes more affordable.”

There are other areas worth discussing

If governments genuinely want to review property tax concessions, then other parts of the system should also be open for discussion.

I have previously raised depreciation claims and quantity surveyor reports on residential investment properties as one example.

That is a separate debate.

The broader point is simple:

if the objective is housing affordability, then the policy should actually improve housing affordability.

Not simply raise more tax from property owners.

The practical takeaway

At this stage, nothing discussed here should be treated as a confirmed change.

We need to wait for the Budget, any formal announcements, draft legislation and ultimately what makes its way through Parliament.

But if CGT changes do come forward, the debate needs to go beyond the headline.

We should be asking:

  • Who actually needs to sell?
  • Who has the ability to hold?
  • Who can defer the tax?
  • Does the policy create more housing?
  • Does it improve affordability?
  • Or does it mainly increase the tax bill when ordinary investors eventually sell?

Tax systems do not operate in theory.

They operate in real life.

And in real life, the people with the most flexibility often have the most options.

If you have a view on where CGT reform should sit in the housing debate, I would be interested to hear it.
