The end of the financial year is a great time to review your superannuation.
Many people know they should do something before 30 June, but they’re not sure whether making an extra super contribution is worthwhile or where to start.
This guide explains how a personal deductible super contribution works, who it may be suitable for and the simple steps involved in claiming a tax deduction.
What is a personal deductible super contribution?
A personal deductible super contribution is money that you contribute to your own super fund from your personal savings.
If you meet the eligibility requirements, you may be able to claim that contribution as a tax deduction. This can reduce the amount of income tax you pay while helping you build your retirement savings in one of Australia’s most tax-effective investment environments.
Is this strategy suitable for everyone?
Not always.
Whether this strategy is appropriate depends on several factors, including:
• your taxable income
• your available concessional contribution cap
• whether you have any unused concessional contribution caps from previous financial years
• your cash flow and future financial needs
Because every person’s circumstances are different, it’s important to understand how this strategy fits within your overall financial plan before making a contribution.
How do I know how much I can contribute?
This is one of the questions we are asked most often.
There are several ways to check your available contribution limits.
Option 1 – Log in to your myGov account (linked to the ATO)
If your myGov account is linked to the Australian Taxation Office (ATO), you may be able to view your concessional contribution cap together with any available unused concessional contribution caps that may be carried forward from previous financial years.
Option 2 – Contact your super fund
Your super fund may be able to provide information about your recent contributions and explain the different ways you can make a personal contribution.
Option 3 – Speak with your accountant or financial adviser
If you’re unsure, it’s always better to ask before making a contribution. We can help calculate your available contribution limits and ensure the strategy is appropriate for your circumstances.
Exceeding your contribution cap may result in additional tax, so taking a few minutes to check beforehand can save problems later.
How do I make the contribution?
Every super fund is slightly different, but most offer a number of convenient ways to make a personal contribution, including:
- BPAY
- Electronic Funds Transfer (EFT)
- Direct Debit
- Online member portal
Your super fund’s website will explain the available payment methods and provide the payment details you’ll need.
Importantly, don’t leave it until the last minute. Your contribution must generally be received by your super fund before the end of the financial year. Many super funds also have their own processing cut-off dates, particularly for BPAY and electronic transfers.
How do I claim the tax deduction?
Making the contribution is only part of the process.
If you intend to claim a tax deduction, you must also complete a Notice of Intent to Claim or Vary a Deduction for Personal Super Contributions.
Most super funds make this form available on their websites, and many also allow it to be completed through their online member portals.
Once submitted, your super fund will send you a written acknowledgement confirming your notice has been accepted.
Important: Don’t lodge your income tax return until your super fund has acknowledged your Notice of Intent. If you lodge your tax return first, you may lose the ability to claim the tax deduction.
Common mistakes to avoid
Some of the most common mistakes we see include:
- leaving the contribution until the final days of June
- forgetting to lodge the Notice of Intent
- lodging your income tax return before receiving acknowledgement from your super fund
- exceeding your available contribution cap
- assuming the strategy is suitable without first obtaining advice
Fortunately, most of these mistakes are easy to avoid with a little planning.
