学生です。働いてはいないです。銀行からT5が送られてきました。セービングアカウントの利子等のみの収入ですが、これはタックスリターンしたほうがいいんでしょうか?以前どこかでやらなくてもいい、ということをみたきがしたのですが。。。

どなたかおしえてください。

タックスリターンはしておいた方がいいですよ。 GST/HSTがいくらか戻ってきたりしますし、仕事始めてから学生の時の学費のクレディットを使えたりします。
Quick Taxでオンラインで申請できます。　学生なら無料です。

　

利子のみの収入なら、逆に払うことになるのでは？（額が大きくなければ控除で０になると思いますが）

しなくてもいいと思います。

ただ、タックスリターンは義務なので本当はしないといけないはず。でも学生でSINカードもってないならしなくてもいいかも？

誰か詳しい人教えてあげてください。

You must file a return for 2009 if any of the following situations apply:

•You have to pay tax for 2009.

•We sent you a request to file a return.
•You and your spouse or common-law partner elected to split pension income for 2009. For more information, see line 115 - Other pensions or superannuation, line 116 - Elected split-pension amount, line 129 - RRSP income and line 210 - Deduction for elected split-pension amount.
•You received Working Income Tax Benefit (WITB) advance payments in 2009, and you want to apply for WITB advance payments for 2010.
•You disposed of capital property in 2009 (for example, if you sold real estate or shares) or you realized a taxable capital gain (for example, if a mutual fund or trust attributed amounts to you, or you are reporting a capital gains reserve you claimed on your 2008 return).
•You have to repay any of your Old Age Security or Employment Insurance benefits. For more information, see line 235 - Social benefits repayment.
•You have not repaid all amounts withdrawn from your registered retirement savings plan (RRSP) under the Home Buyers’ Plan or the Lifelong Learning Plan. For more information, see Guide RC4135 - Home Buyers’ Plan (HBP) or Guide RC4112 - Lifelong Learning Plan (LLP).
•You have to contribute to the Canada Pension Plan (CPP). This can apply if, for 2009, the total of your net self-employment income and pensionable employment income is more than $3,500. See line 222 - Deduction for CPP or QPP contributions on self-employment and other earnings.



Even if none of these requirements apply, you may still want to file a return if any of the following situations apply:

•You want to claim a refund.

•You want to claim the WITB for 2009.
•You want to apply for the GST/HST credit (including any related provincial credit). For example, you may be eligible if you turn 19 before April 2011.
•You or your spouse or common-law partner want to begin or continue receiving Canada Child Tax Benefit payments.
•You have incurred a non-capital loss (see line 236 - Net Income) in 2009 that you want to be able to apply in other years.
•You want to carry forward or transfer the unused part of your tuition, education, and textbook amounts (see line 323 - Tuition, education and textbook amounts).
•You want to report income for which you could contribute to an RRSP in order to keep your RRSP deduction limit for future years up to date.
•You want to carry forward the unused investment tax credit on expenditures you incurred during the current year (see line 412 - Investment tax credit).
•You receive the Guaranteed Income Supplement or Allowance benefits under the Old Age Security Program. You can usually renew your benefit simply by filing your return by April 30. If you choose not to file a return, you will have to complete a renewal application form. This form is available from the Service Canada website.

払う税金があるのなら、タックスリターンは義務ですが、そうでない場合、申請すればとぴぬしさんがお金をもらえるという場合、申請してもいいが、義務ではないです。学生さんだったらほかの項目に当てはまることはあまりないと思いますが、一応全部目を通してくださいね。
