If you have T-slips from income you have made, you will need to claim the proper year slips on the proper year tax return. If you already filed last year's return and did not include the income, you will need to refile/amend that return. If you never filed last year, you will need to complete a 2023 return adding your income and then complete a 2024 return including your income from 2024.
