@Britneek , in the past when discussing this exact situation with my accountant, you can claim any costs associated with earning your income from trading activity. You can only write off capital losses against your trading income. Your taxable income, is as you point out would be 126k. Your marginal tax rate on salary would reflect 100k. You may have to pay extra tax overall if your combined income pushes you into a higher marginal tax rate - though I would double check this with your accountant.
