Hi, I don't think you're incorporated, so any income you earn will be yours as a self-employed business, completing the T2151 with your tax return. It's important to collect your revenue and expenses, and to attribute home related expenses to the business. I do this for my wife and my own business. You can get an accounting package but a spreadsheet does the job too.

If you want to track the income and expenses separately from other income then start with an accordion folder to file your paperwork (invoices, receipts, bills).
