只有盈利和政府补贴部分需要按income交税。
quote from CRA:
Income tax considerations
Students who receive money from an RESP must claim their
Educational Assistance Payment as income. Since students typically have limited income while in school, however, they may not be required to pay any income tax on this amount. This depends on individual circumstances. YourRESP provider will issue the student a T4A slip for income tax purposes.
Educational Assistance Payments include the interest earned in the RESP as well as any
Canada Education Savings Grants,
provincial grants and
Canada Learning Bonds received. You can use this money to pay for post-secondary school expenses like tuition, books and transportation.
