Consequently, before you decide to act on any of the information provided, it’s important for you to evaluate its appropriateness for your personal circumstances.

Superannuation is one of the most tax-effective ways to build long-term wealth—but it comes with rules. One of the most important is knowing how much you can contribute each year without triggering extra tax. These limits are called contribution caps, and staying within them can help you grow your retirement savings efficiently and confidently.

The Two Main Types of Contributions

There are two keyways to contribute to your super:

1. Concessional Contributions (CC): These are made from before-tax income and include; Employer Super Guarantee (SG), Salary sacrifice, and Personal contributions you claim as a tax deduction. These contributions are taxed at 15% when they enter your super fund. If your income exceeds $250,000, you may pay an additional Division 293 tax of 15%. Cap for 2025–26: $30,000 per financial year.
   

2. Non-Concessional Contributions (NCC): These are made from after-tax income—you’ve already paid income tax on this money. They’re not taxed when entering your super and form part of the tax-free component of your balance. Cap for 2025–26: $120,000 per financial year, or up to $360,000 over three years using the bring-forward rule (if your total super balance is under $1.9 million).

What Happens If You Go Over the Cap?

Exceeding your contribution caps can lead to unexpected tax bills:

• Excess CCs are added to your taxable income and taxed at your marginal rate (minus a 15% offset).

• Excess NCCs may attract penalty tax of up to 47% unless withdrawn promptly.

If you have multiple super funds, all contributions are counted together—so it’s important to track them carefully.

Strategic Planning Matters

Understanding your caps isn’t just about avoiding penalties—it’s about making the most of your financial opportunities. For example:

• If you’ve had a lower-income year, you might use carry-forward CCs from previous years (if your total super balance is under $500,000).

• If you’ve received a windfall, NCCs can be a smart way to boost your super without triggering tax.

Super is a long game—and knowing the rules helps you play it well. Whether you're salary sacrificing, making personal contributions, or planning a lump sum, staying within your caps keeps your strategy tax-smart and future-focused.
