Debt Recycling and Capital Gains Tax: What Happens When You Sell?

Years of disciplined debt recycling can build a sizeable investment portfolio — one that quietly compounds through dividends, franking credits and capital growth. But eventually, whether to fund retirement, repay a loan or simply lock in profits, you may need to sell some of those holdings. When you do, capital gains tax enters the picture.

CGT basics every debt recycler should know

Capital gains tax (CGT) isn't a separate tax — it's part of your regular income tax. When you sell an investment for more than it cost you, the profit is added to your assessable income for that financial year and taxed at your marginal rate.

The formula is straightforward:

Capital gain = capital proceeds − cost base

Capital proceeds are the sale price (less selling costs such as brokerage). The cost base includes what you originally paid for the asset, plus purchase brokerage, and certain other costs like reinvested distributions that were already assessed as income.

Critically, individual Australian taxpayers receive a 50% CGT discount on gains from assets held for more than 12 months. You include only half the gain in your taxable income. This discount applies to individuals and trusts (at the trustee level) but not to companies or super funds (which have their own rules).

Worked example: selling after holding for over 12 months

Suppose you bought $60,000 of shares as part of your debt-recycling strategy, and three years later you sell them for $110,000. Here's how the CGT calculation works for someone on a 39% marginal rate (including Medicare Levy):

Without the 12-month discount, the tax bill on the same sale would be $19,500 — exactly double. Holding past the one-year mark is the single most powerful lever you have.

Why debt recyclers rarely trigger CGT

The core debt-recycling strategy is built around holding investments and living off the income they produce — dividends, distributions and franking-credit refunds. If you never sell, you never crystallise a capital gain. Many debt recyclers hold their portfolios for decades, only selling in retirement (if at all).

CGT typically becomes relevant in a few situations:

• Repaying the investment loan. If you sell investments to pay off the deductible (DL) loan, you trigger a gain on whatever has grown.
• Rebalancing. Shifting from one ETF or managed fund to another means selling the first, which crystallises any gain.
• Life events. Divorce, redundancy, or an urgent cash need might force a sale you hadn't planned for.

The lesson: if you can avoid selling, CGT stays dormant. The strategy rewards patience.

Timing levers to reduce the CGT bill

When selling is unavoidable, you can still influence how much tax you pay:

1. Always hold past 12 months. The 50% discount is non-negotiable for anyone managing a debt-recycling portfolio. Check your purchase dates before placing a sell order.
2. Spread sales across financial years. Selling $200,000 of investments in one year pushes you into a higher marginal bracket. Splitting the sales across two or three years keeps more of each gain taxed at a lower rate.
3. Sell in lower-income years. A career break, parental leave, sabbatical or the early years of retirement often mean lower taxable income. Crystallising gains when your marginal rate drops from 39% to 32% — or even 18% — can save thousands.
4. Offset gains with capital losses. If you hold any underperforming investments, selling them in the same financial year lets you offset the loss against your gains before the 50% discount is applied. You can also carry forward unused capital losses to future years.

What happens to your loan when you sell

This is where debt recycling and CGT intersect in a way many people miss. If you use the sale proceeds to repay your deductible (DL) investment loan, that slice of debt ceases to exist — and so does the interest deduction attached to it.

You face a trade-off: eliminating the DL reduces your ongoing borrowing costs, but you also lose the annual tax deduction on that interest. In some cases, keeping the loan and redeploying the sale proceeds into new income-producing investments may be more efficient — though this depends on your overall position, the interest rate, and your marginal tax rate.

If you do repay the DL, the proceeds must go directly to that loan (not to the non-deductible home-loan portion) to keep the remaining structure clean. Misdirecting funds can contaminate the loan and jeopardise deductions on the remaining balance.

Cost base: get your records right

The ATO expects you to be able to prove your cost base for every parcel of shares or units you sell. For a debt-recycling portfolio built up over many years, that means keeping:

• Purchase confirmations — the trade date, number of units, price per unit and brokerage for every purchase.
• Reinvested distributions — if your managed fund or ETF offers a distribution reinvestment plan (DRP), each reinvestment is a new acquisition at a specific price and date. These add to your cost base and reduce the eventual gain.
• Corporate actions — share splits, consolidations, demergers and return-of-capital payments can all adjust your cost base.
• Selling costs — brokerage on disposal is deducted from proceeds.

Most brokers and fund registries provide annual tax statements that summarise this information, but you should keep your own records as well. A well-maintained spreadsheet — or the records section in your broker's platform — can save hours of work (and significant dollars in avoided errors) at tax time.

Two common misconceptions

Your home's CGT exemption does not extend to these investments. Your main residence is exempt from CGT, but the shares, ETFs and funds you buy through debt recycling are ordinary investment assets and are fully subject to CGT on disposal. The fact that the loan is secured against your home makes no difference — the exemption follows the asset, not the security.

Death and estates are more complex than most people expect. When an individual passes away, their investments pass to beneficiaries with a modified cost base. The CGT event is generally deferred until the beneficiary eventually sells, and the discount period includes the deceased's holding period. The rules are intricate and interact with superannuation, testamentary trusts and the broader estate plan — this is an area where professional advice is essential.
