Tax loss selling is a strategy that investors can leverage to minimise their net capital gains during a financial year for tax purposes. While tax loss selling can be used at any time, it is most often implemented in the lead up to the end of each financial year. This makes June a particularly good time to review your investment portfolio and decide whether to leverage a tax loss selling strategy to help offset any capital gains you incurred for the year.

Tax loss selling for Australian investors

What is tax loss selling?

Tax loss selling (or tax loss harvesting) involves selling investments that have incurred capital losses in order to “net out” or offset capital gains realised during the year. Essentially, if you wish to sell out of certain unprofitable investments in your portfolio, you may choose to use tax loss selling as a way to alleviate some of that loss and re-align your portfolio with your investing strategy, even if the net effect is still negative.

While many investors choose to leverage tax loss selling towards the end of the financial year, you can harvest losses at any time. The amount of money you save in taxes will differ depending on your tax rate (individual/trust, SMSF, company), but it should be noted that higher tax rates will apply for investments you’ve held for less than a year (short-term capital gains) than investments you’ve sold after holding them for more than a year.

How does tax loss selling work?

To help explain how tax loss selling works, let’s look at an example calculation:

Let’s say you bought 500 shares of Stock A a few years ago, when the price was $30. Today, it’s trading at $300, meaning its value has increased by $135,000. At some point, you also bought 500 shares of Stock B when the price was $100. Since then, the share price has gone down to $50, decreasing its value by $25,000.

Holding Purchase Value Market Value Capital Gain
Stock A $15,000 $150,000 $135,000
Stock B $50,000 -$25,000 -$25,000

While you could hold onto Stock B in the hope that its share price will recover, you could also sell both Stock A and Stock B before the end of the financial year to offset some of the gains from your sale of Stock A with your sale of Stock B. Doing so may not only soften the impact of the loss, but it could also be a good opportunity to shed an unprofitable stock and rebalance your investment portfolio.

How to model tax loss selling opportunities with Sharesight

If you hold investments that have suffered losses this year, Sharesight’s unrealised CGT report can help you calculate how to offset your capital gains by:

  1. Displaying the CGT position for all your current holdings, if you were to sell them on the date of the report. These are broken down into:
    • Short term capital gains (unrealised)
    • Long term capital gains (unrealised)
    • Capital losses (unrealised)
  2. Modelling the CGT that would occur across your portfolio if the shares identified were sold on the report date.
  3. Allowing you to modify the CGT sale allocation method at the overall portfolio or individual holding level to determine your optimum position.

Sharesight Unrealised Capital Gains Tax Report Sharesight’s unrealised CGT report makes it easy for investors to model different tax loss selling scenarios.

The report uses the ‘discount method’ for shares that have been held for more than one year and the ‘other method’ for shares held for less than one year. The discount rate is based on the tax settings of an Australian portfolio:

  • Individuals / Trust – CGT discount of 50 %
  • Self Managed Super Fund – CGT discount of 33⅓ %
  • Company – CGT discount of nil

The report also allows you to specify the sale allocation method at the overall portfolio and individual holding level to determine your optimum position, including:

  • First In, First Out (FIFO) – Sharesight assumes that you sell your longest held shares first.
  • Last In, First Out (LIFO) – Sharesight assumes that you sell your most recently purchased shares first.
  • Maximise Gain – Sharesight assumes that you sell shares with the lowest purchase price first.
  • Minimise Gain – Sharesight assumes that you sell shares with the highest purchase price first.
  • Minimise CGT – Sharesight assumes that you sell shares that will result in the lowest capital gains tax first. This method is more sophisticated than the ‘Minimise capital gain’ method because it takes into account the Australian CGT discounting rules.

Notes on the unrealised CGT report

  • The unrealised CGT report is designed for forecasting purposes only. Refer to the capital gains tax report to calculate your actual (realised) taxable capital gain income for a specific period.
  • You may carry forward losses from the previous reporting period by clicking on the ‘Advanced options’ link.
  • It’s a good idea to run the report throughout the year, not just at the end, in order to stay on top of opportunities to offset gains and losses throughout the year. You may want to share secure portfolio access with your accountant and/or adviser, so they can keep this in mind as well.
  • The unrealised CGT report is available on Australian Investor and Expert plans.
  • For more information, visit the unrealised CGT report help page.

Avoiding wash sales

In 2008, the Australian Tax Office (ATO) issued issued tax ruling TR 2008/1, which specifically outlaws arrangements where “ substance there is no significant change in the taxpayer’s economic exposure to, or interest in, the asset, or where that exposure or interest may be reinstated by the taxpayer”.

In other words, the ATO prevents investors from selling a stock in one financial year to take advantage of a capital loss event, only to buy that stock again in the new financial year. This is known as a “wash sale” and the ATO will disallow the loss if the sole intention of the sale was to minimise tax. As Sharesight Executive Director Andrew Bird said, “if you are going to sell, make sure you really mean it. If you still believe in that stock then choose a different ‘loser’ to sell to offset your gain.”
