5 Wealth Decisions You Shouldn’t Make in Isolation

Joanna* doesn’t make decisions lightly. She and her late husband worked hard for their money, so when she sees one of her daughters struggling to buy a home, she decides to sell an investment property and use part of the proceeds to help towards the purchase.

It sounds simple enough. And while her daughter can get on the property ladder, the process ends up being messier and more expensive than it needed to be, had she sought strategic advice from her accountant. The capital gain lands in a year where other income is already elevated, the gift isn't documented, and the estate plan doesn't reflect the advance distribution. All create flow-on issues that could have been avoided.

In this article, I discuss several common scenarios that seem straightforward, but can have knock-on effects on other areas of your wealth and life.

If you're at a stage where you’re making decisions that involve significant financial assets, it’s important to understand the impact on your wealth position as a whole. That way, you can be sure you’re making the right moves at the right time.

Scenario 1: Selling an asset

Whether it's an investment property, share portfolio, or business interest, selling a significant asset means the timing, structure, and broader context all matter.

The most common oversight is treating the capital gain as a standalone figure rather than considering its impact on total taxable income for the year. A large gain in a year where other income is already substantial can push you into a higher effective tax rate and affect your Medicare Levy Surcharge position.

The 50% CGT discount for assets held longer than 12 months remains in place at the time of writing. It’s worth noting that proposed changes announced in the 2026–27 Budget, including the replacement of the discount with cost base indexation and a 30% minimum tax on net capital gains, are intended to take effect from 1 July 2027. If you're planning a sale, understanding how the current and incoming rules interact with your position is important.

Timing a sale across two financial years, or considering whether a pension stream from superannuation could reduce assessable income in the same year, are strategies that can only be considered when looking at the whole picture before selling an asset.

Scenario 2: Gifting money

While Australia has no gift tax, gifting money has flow-on effects to estate planning and family dynamics.

An undocumented gift to one child, particularly if that gift is large, can create ambiguity in your estate. If your will doesn't address it, other beneficiaries may have reasonable grounds to question whether the gift was intended as an advance on the estate or an additional distribution. The friction it creates, sometimes years later, can strain even the most solid of families.

There's also the question of whether a gift is actually the right structure, or whether a documented loan would better serve both parties. A loan agreement records the transaction clearly for estate purposes. It can offer a degree of protection in the event of a relationship breakdown; courts may treat a documented loan differently from a gift when dividing assets, though the outcome depends on the specific circumstances. And it creates a record that your executor can work with.

Knowing how and when to gift money to your adult children is just as important as knowing how much to gift.

Scenario 3: Acting as guarantor on a child's property

Guaranteeing a child's mortgage feels like a way of helping without actually giving money. And in some respects, it is. But it carries obligations that are worth understanding clearly before you sign.

As guarantor, you are legally liable if your child cannot meet their repayments. If your child defaults, the lender can pursue you for the shortfall, and that can extend to assets you hold personally, depending on the nature of the guarantee.

There's also the impact on your own borrowing capacity. A guarantee shows up as a contingent liability, which means it can affect your ability to access credit for your own purposes, even if the child is meeting their repayments without difficulty.

A limited guarantee, where your exposure is capped at a specific amount, typically the difference between the loan amount and a target loan-to-value ratio, is generally preferable to an unlimited one. You’ll also need to consider your exit strategy. As your child builds equity, there should be a plan to release the guarantee, and it should be documented at the beginning.

This is also a decision that interacts with your estate plan. If your will or any existing structures treat your children differently, a guarantee and the risk it creates, is worth including in that conversation.

Scenario 4: Drawing from superannuation

Superannuation is often the largest single asset outside the family home, and yet decisions about how and when to draw from it are frequently made without reference to everything else.

The tax treatment of a superannuation withdrawal depends on both your age and the components you're drawing from. Withdrawals from the taxable component can be assessable income, which affects your overall tax position for the year. Once you're over 60, most withdrawals from a taxed fund are tax-free, but that doesn't mean the decision is straightforward.

Sequencing is one of the most significant factors in superannuation. Drawing a large lump sum in a year where other income is elevated, whether that’s from an asset sale, a business distribution, or a property settlement, can have consequences that a pension stream, drawn over time, might have avoided entirely. The difference between a lump sum withdrawal and commencing an account-based pension, and whether or not that pension is reversionary, affects how the money is taxed, how it interacts with your broader income, and how it fits into your estate.

Superannuation also sits outside your estate by default and doesn't form part of your will unless you've specifically directed it there. Instead, it's governed by your binding death benefit nomination. A change in your personal or family circumstances may warrant a review of who receives your super and in what form.

Scenario 5: Selling the family home to downsize

Downsizing sounds simple, but it is often one of the more complex financial transitions a person makes.

The family home is generally exempt from capital gains tax under the main residence exemption, but partial exemptions apply if your home has ever been used to produce income. Say, if you've been absent for extended periods, or if the property is on land exceeding two hectares. These details come up regularly, and the tax consequences can be significant.

Eligible Australians aged 55 and over have been able to make a downsizer contribution of up to $300,000 each ($600,000 per couple) into superannuation from the proceeds of selling their home, without it counting toward the standard contribution caps. This is a meaningful opportunity, but it has conditions, including that the home must have been held for at least 10 years, and the contribution must be made within 90 days of settlement.

Your broader financial picture also changes substantially when the family home is sold. If proceeds are held in cash or invested, they become assessable assets. If a new property is purchased, stamp duty, financing, and structure decisions all come into play. And if part of the proceeds are being used to help adult children, that is another consideration that requires additional planning.

Downsizing works best when the full sequence - the sale, the super contribution, the new purchase, and any family arrangements- is mapped out in advance.

Each of these scenarios looks straightforward and is usually manageable on its own. The complexity arises when they intersect. This is when having a strategic conversation with your accountant before making any money moves can be incredibly valuable.
