You don't need to have two separate accounts, but if you have prepared your return on your own, she would have to have to prepare a return for just herself. And, yes, she would need to enter your information on her return.

Thanks. Here i choose the option of preparing tax with spouse. I put all my t4 and my spouse t4 into the respective options. 

My question is: if I submit the file now, does she(spouse) still need to submit her tax file?
