T4BOX28的问题：如图，T4是这样的，以前没注意到，今年才注意如果28选yes退税额能多好几百。公司是美国公司，加拿大部分没有payroll，给美国总部打了电话发了ticket也没人理，只好这里问问，这个O算不算yes？ -166(彩虹) @曼省华人论坛:曼省枫下论坛 The Rolia Forum of Manitoba

一般来说， X 表示 Checked, 即yes的意思。空白或零表示 No. -zhylj(爱谁谁); 2016-2-26 {191} (#9965259@0)
An X under CPP/QPP, EI, or PPIP in box 28 of your T4 slip indicates that your earnings are exempt from these withholdings. The majority of taxpayers are not exempt, so the default here is No.

CPP, EI 一般来说是强制性征收的，没有豁免 (exempt)。PPIP, Provincial Parental Insurance Plan，绝大多数单位都没有征收此项，是否豁免没有任何意义。 -zhylj(爱谁谁); 2016-2-27 {393} (#9965735@0)
Provincial Parental Insurance Plan - PPIP

A Canadian tax deduction relating to taxes that are paid or payable on regular or self-employed income. The Provincial Parental Insurance Plan (PPIP) gives maternity, paternity, parental and adoption benefits to qualified persons. This aid is to support and encourage parents staying home with their children for the first year of the child's life.
