Key Takeaways

• Adult children are usually treated as non tax dependants for super death benefit tax purposes
• The tax generally applies to the taxable component, not the whole balance
• The tax free component is always paid tax free
• In many taxed super funds, the taxable taxed element is commonly taxed at up to 15 percent
• If a benefit is paid directly from the super fund, the Medicare levy may also apply
• For many couples, this becomes a second death issue because super paid to a spouse is generally tax free

Step 1: Understand Tax Dependants vs Non Tax Dependants

Super death benefits tax depends heavily on who receives the benefit.

At a high level, the tax law treats some beneficiaries as tax dependants.

Others are treated as non tax dependants.

Adult children are often treated as non tax dependants, which is why tax can apply.

There are exceptions in some situations, such as where an adult child is financially dependent or has a disability, but most adult children are treated as non tax dependants.

This is different to a spouse, where super is generally paid tax free.

That is also why many families only run into this issue later.

Often after both spouses have passed away and the remaining super is paid to adult children.

Step 2: Understand Tax Free vs Taxable Components

Super is not one single pot for tax purposes.

It has two components:

Tax free component
Taxable component

The tax free component is always paid tax free.

The taxable component is the part that can create tax issues for adult children.

What Tax Rates Apply to Adult Children?

This depends on the type of taxable component and how the benefit is paid.

A simple summary looks like this.

In many practical scenarios, people estimate the taxed element outcome as:

15 percent plus Medicare levy
roughly 17 percent

But it is not automatic.

If the death benefit is paid directly from the super fund to the beneficiary, Medicare levy commonly applies.

If the death benefit is paid to the estate first, Medicare levy generally does not apply, although tax on the taxable component can still apply.

Super funds typically withhold the relevant tax before paying the benefit.

Important: Different outcomes can apply depending on the fund type and how the death benefit is structured and paid. This article stays at a general educational level.

Worked Example: $800000 Super Paid to Adult Children

Assume a parent dies and their adult child receives a lump sum death benefit.

Super balance
$800000

Tax free component
$200000

Taxable component
$600000

Only the taxable component is potentially taxed.

If the taxable component is a taxed element paid directly

A common rough estimate is:

Taxable component
$600000

Tax at roughly 17 percent
$102000

The after tax amount received from the taxable component would be roughly:

$498000

Plus the tax free component of $200000, which is not taxed.

So total received would be roughly:

$698000

If the taxable component includes an untaxed element

Tax can be higher.

For example, if the untaxed element rate and Medicare levy applied as a rough estimate:

30 percent plus Medicare levy
roughly 32 percent

$600000 x 32 percent
$192000

That is why the fund type and component details matter.

Is the Tax Always 17 Percent?

Not always.

17 percent is a common shorthand estimate when:

• the benefit is paid to adult children
• the taxable component is a taxed element
• the Medicare levy applies because the benefit is paid directly from the fund

But the real outcome depends on the details.

If you want to plan properly, the starting point is always to confirm:

Your tax free component
Your taxable component
Whether there is any untaxed element
Whether the benefit is likely to be paid directly or via the estate

Why Recontribution Strategies Come Up Here

This death benefits tax issue is one of the main reasons recontribution strategies exist.

When This May Not Be a Big Issue

Two common situations reduce the relevance.

You expect to spend most of your super

If the balance at death is likely to be small, the tax impact may not be meaningful.

Your spouse is the likely first beneficiary

Super paid to a spouse is generally tax free.

So the main tax issue often arises later, when the remaining balance passes from the surviving spouse to adult children.

That is why this is often a second death planning issue.
