First-Time Investor? 7 Tax Mistakes That Could Cost You Thousands
Common myths and misconceptions that trip up new investors
Over 2 million Australians started investing for the first time in the past three years. Trading apps and micro-investing platforms have made it easier than ever to buy shares, ETFs, and other investments. But while buying is easy, understanding the tax implications is not.
We see the same mistakes repeatedly: missed dividend income, incorrect cost base calculations, misunderstanding franking credits, and more. Here are the seven myths that cost new investors the most, and the truth that can save you money.
Mistake 1: Not Reporting All Dividends
The Mistake
Many new investors assume that if they reinvest dividends through a DRP (dividend reinvestment plan), the dividends are not taxable because no cash was received.
The Reality
Reinvested dividends are fully taxable in the year you receive them, just like cash dividends. The fact that you used them to buy more shares does not change their tax treatment. The ATO receives data directly from share registries about all dividends paid, whether reinvested or not.
The silver lining: the reinvested amount becomes part of your cost base for the new shares, reducing future capital gains when you sell.
What to Do
Keep all dividend statements, including DRP statements. Include every dividend on your tax return. TaxBot imports dividend data automatically and tracks your cost base including DRP parcels.
Mistake 2: Ignoring Franking Credits
The Mistake
First-time investors often ignore franking credits on their dividend statements, not understanding what they represent or how to claim them.
The Reality
Franking credits represent tax the company has already paid on its profits. When you include them in your tax return, you are essentially getting credit for tax already paid on your behalf. If your marginal tax rate is lower than the 30 percent company tax rate, you may receive a refund of the excess.
Example: You receive $700 in dividends with $300 in franking credits. Your assessable income is $1,000 (dividends plus credits). If your marginal rate is 19 percent, you owe $190 in tax but have $300 in credits. You receive a $110 refund.
At the 37 percent marginal rate, you would owe $370 on the $1,000 but have $300 in credits, so you only pay an additional $70.
What to Do
Always include franking credits on your tax return. Check your dividend statements carefully. TaxBot automatically calculates your franking credit position.
Mistake 3: Wrong Cost Base for CGT
The Mistake
Calculating capital gains using the wrong cost base is one of the most common errors. New investors often use only the purchase price, forgetting fees, or worse, use the current price minus purchase price without accounting for corporate actions.
The Reality
Your cost base includes the purchase price plus brokerage fees on purchase, plus any other incidental costs. It is also affected by corporate actions: share splits, consolidations, demergers, capital returns, and bonus issues can all change your cost base.
Example: You bought 100 shares at $10 each plus $20 brokerage equals a $1,020 cost base. The company then returned $1 per share capital. Your new cost base is $920 ($1,020 minus $100 capital return). If you later sell for $1,500 with $20 brokerage, your capital gain is $1,500 minus $920 minus $20 equals $560, not $1,500 minus $1,000 equals $500.
What to Do
Keep records of every purchase, including brokerage. Track corporate actions carefully. TaxBot connects to your broker and automatically adjusts cost bases for corporate actions.
Mistake 4: Forgetting the 12-Month CGT Discount
The Mistake
New investors sometimes do not realise the significant benefit of holding investments for over 12 months, or they sell just before reaching this threshold.
The Reality
If you hold an investment for at least 12 months before selling, you are only taxed on 50 percent of the capital gain. This CGT discount is one of the most valuable tax concessions available to Australian investors.
Example: You have a $10,000 capital gain. If you held less than 12 months, at a 37 percent marginal rate, you owe $3,700 in tax. If you held over 12 months, you only pay tax on $5,000, owing just $1,850. That is a $1,850 saving for simply waiting.
What to Do
Check your holding period before selling. If you are close to 12 months, consider waiting. TaxBot shows you which holdings qualify for the discount and which are approaching eligibility.
Mistake 5: Thinking Losses Reduce All Income
The Mistake
After experiencing their first investment loss, new investors sometimes expect it to reduce their salary income and are surprised when their tax bill is not much lower.
The Reality
Capital losses can only offset capital gains. They cannot reduce your salary, interest, rent, or other ordinary income. If you have more losses than gains in a year, the excess carries forward to offset future capital gains, but it never touches ordinary income.
The exception: if you are a share trader (trading as a business rather than investing), losses may be treated differently. But most people are investors, not traders.
What to Do
Understand that losses are valuable but have limited use. Consider timing gains and losses strategically. TaxBot tracks your capital gains and losses and shows optimal strategies for using carried forward losses.
Mistake 6: Not Keeping Records
The Mistake
Many new investors delete confirmation emails, do not download statements, and assume their broker will keep records forever.
The Reality
You must keep records for five years after you sell an investment. Brokers may not keep records that long, especially if you close your account. Without records, you may not be able to prove your cost base, potentially paying more CGT than necessary.
The ATO can request evidence of your cost base during an audit. If you cannot provide it, they may assume a zero cost base, meaning your entire sale proceeds are taxable as a capital gain.
What to Do
Download and store all trade confirmations, dividend statements, and annual tax summaries. TaxBot stores all your investment records securely in the cloud, accessible anytime.
Mistake 7: Assuming Micro-Investing Is Tax-Free
The Mistake
Users of micro-investing apps like Raiz and Spaceship sometimes believe that because the amounts are small, taxes do not apply.
The Reality
Tax obligations apply regardless of investment size. Micro-investing platforms invest your money in ETFs or funds that pay distributions, which are taxable. Selling your holdings triggers CGT calculations just like any other investment.
The challenge with micro-investing is the complexity: frequent small purchases create many cost base parcels, and distributions can include multiple components (dividends, capital gains, foreign income) that must be correctly reported.
What to Do
Treat micro-investments the same as any other investment. Keep records and include all distributions on your tax return. TaxBot integrates with major micro-investing platforms to simplify tracking and reporting.
