Take stock of your portfolio today—review your records for non covered securities and get ahead of tax time surprises.

Non-covered securities are making waves in the Australian financial landscape this year, especially as the ATO tightens compliance and investors look to optimise their portfolios. If you hold shares, ETFs, managed funds, or bonds acquired before certain reporting rules kicked in, you may be dealing with non-covered securities—and the implications for tax and record-keeping are significant in 2026.

What Are Non-Covered Securities?

In simple terms, non-covered securities are financial instruments that are not subject to the latest reporting requirements for cost basis by brokers and financial institutions. The concept originated in the US under IRS regulations, but as Australia updates its own compliance and reporting standards, the distinction is increasingly relevant for local investors. Typically, non-covered securities include:

For Australian investors, the key issue is that brokers or platforms may not provide the cost base or detailed transaction history for these assets. That makes tax time—and capital gains tax (CGT) calculations—more complex.

2026 Policy Updates: What’s Changed?

This year, the ATO has rolled out enhanced digital pre-fill services for investment income and capital gains, drawing more data directly from brokers and registries. However, non-covered securities remain a blind spot:

In practical terms, 2026’s compliance push means investors with non-covered assets must be extra vigilant. If you sell non-covered shares, you’ll need your own records to correctly calculate and report capital gains or losses.

Real-World Example: Selling Non-Covered Shares

Consider Jane, who bought 2,000 shares in an ASX-listed company back in 2008. In 2026, she decides to sell. Her broker’s online portal provides all the details for her recent ETF purchases, but not for the 2008 shares—they’re classified as non-covered. Jane must dig up her original contract note (or bank statement) to establish her cost base. If she can’t, she risks overpaying CGT or facing ATO scrutiny.

This scenario isn’t rare. Australians who’ve held shares for a decade or more, or who’ve received legacy managed fund units, often discover the records are incomplete. Without proactive record-keeping, the tax outcomes can be costly.

How to Manage Non-Covered Securities in Your Portfolio

Key Takeaways for 2026

Non-covered securities might sound like an obscure technicality, but for thousands of Australian investors, they’re a real compliance challenge. As the ATO’s digital net tightens, legacy assets can slip through the reporting cracks—leaving you responsible for accurate records and tax outcomes. A proactive approach in 2026 can save time, stress, and money down the track.
