Non-Covered Securities in Australia: Tax Rules & Investor Guide 2026

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:

• Securities acquired before a specific compliance date—for example, shares purchased before July 1, 2011, may not have mandatory cost basis reporting.

• Unlisted managed funds or legacy investments that predate digital reporting systems.

• Foreign securities held outside platforms with integrated reporting to the ATO.

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.

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:

• Brokers are not required to report cost base data for non-covered securities. The onus remains on you to track purchase prices, dividend reinvestments, and corporate actions.

• ATO data-matching programs now focus heavily on post-2011 acquisitions, but legacy holdings may not be fully captured.

• Managed funds and ETFs acquired before industry-wide electronic reporting often still lack digital cost base records.

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.

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.

• Keep meticulous records: Store original purchase confirmations, dividend statements, and any correspondence about corporate actions.

• Digitise your paperwork: Scanning old documents and uploading them to a secure cloud folder makes future reporting far easier.

• Consider professional help: For large or complex portfolios, a tax agent or financial adviser can help reconstruct cost bases and navigate ATO queries.

• Review your holdings annually: Identify which assets are non-covered and ensure you have sufficient records before selling.

• Stay updated on policy changes: While 2026 hasn’t seen a shift to retrospective cost base reporting, future compliance moves could change the game.

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.
