Does turbo tax calculate the cpp for self employed individuals or do you need to input your own calculations?

Thanks for your question. CPP on self employment is calculated automatically by the software.  As you are self- employed, you will also have to pay the employer's portion of CPP.  The CPP calculated will be included as part of your tax liability on the tax return.
