Hey guys, I was just wondering what the process and calculations needed for the following tax situation: If you are working full time with a salary so meaning tax is already deducted by employer. While also being self-employed and earning a profit online. How would you calculate the amount of tax you need to pay for your online earnings and which forms would you need to fill out? I'm sure there are people in this situation and know the course of action to take? Please no posts with "ask an accountant". I'm just posting to see members advice. Cheers guys!
