Yes. As eToro stated on their website, it's your responsibility to calculate the tax and pay them in your country of jurisdiction. Just like with any trading platform, you have to pay taxes if you made profits but it's important for you to know the specific guidelines and regulations in your country. For example, tax rates in the UK (click here to know more about eToro UK taxes) are not the same for those who are in Australia. It varies from one country to another.
If you want to know the exact amount that you need to pay, the simplest way to do this is by checking your account statement first to see the income that you made and from there you'll be able to estimate or compute for the taxable income that you will have to indicate on your tax return. Hope this helps.
