What do you include with your return and what records do you keep?

If you are filing a paper return, include one copy of each of your information slips. These slips show the amount of income that was paid to you during the year, and deductions that were withheld from that income. Notes on each information slip tell you where to report the income and deductions on your return.

Some common information slips are:

• T4, Statement of Remuneration Paid slips, which show employment income and payroll deductions;
• T4A, Statement of Pension, Retirement, Annuity and Other Income slips, which show scholarship, fellowship, and bursary income, or payments from a registered education savings plan; and
• T5, Statement of Investment Income (slip), which shows investment income such as interest from financial institutions or from Canada Savings Bonds.

The information in your tax package will tell you what supporting documents you need to attach to your return, such as certificates, forms, schedules, or official receipts.

Even if you do not have to attach certain documents to your return, or if you are filing your return electronically, keep them in case we select your return for review. You should keep your supporting documents for six years.

You should keep a copy of your return and the related notice of assessment, and any notice of reassessment. These can help you complete your return for the following year. For example, your notice of assessment will show the tuition, education and textbook amounts you can carry forward.
