I'm a pensioner, and this is the first time I've sold some shares. In the past, I've added franked dividends, which I understand, but this year we have pre-filled data. I'd like know what sould adding or any advice
Regarding the sale: I sold shares or units (reference: CBA) on 15/05/2025 for $36,730.60. Do I need to fill out more details on capital gains or losses?
Yes. the price you bought the shares, called cost base.
You pay tax on the capital gain (profits from selling). If you put nothing, then you're assuming you paid $0 for the shares. Which would most likely mean you would overpay the tax.
When you refer to paid for shares, are you referring to the original first purchase in year 2000, or are you saying you have always owned them but sold some this time around? This is where I am puzzled.
Generally, the cost of buying would be your cost base. There can also be other things that affect the cost base.
If you need help, it may be a good idea to see a tax agent to sort out the capital gain.
