Base Income Tax Deduction for CPP

[Darpat]

My mother is about to receive CPP cheques. I am aware that federal income tax is not deducted automatically from these cheques. What is the base percentage that should be deducted from her cheques so she doesn't end up paying money back to goverment?

Thanks in advance for your help.

Do you know what her annual benefit amount will be? Any other sources of income?
