大家好，我才到加拿大上班，税务方面一头雾水。

' Z. g$ I7 H7 M6 z8 J: r# O* j; A入职时小蜜给我一份CPT1表格填写。"Aplication to Canada Revenue Agency for CPP/EI Exemption". 请问这个表格是申请什么的？是申请不缴CPP/EI吗, 还是其他意思？

6 S3 S* g0 F3 h% F2 I2 |  D: }, ~表格里有这么一段话: ”XXX must make CPP and EI deductions from workers. However, if you interpret your income to be CPP/EI exempt, you must apply to CRA directly for a ruling on whether your employment is pensionable and/or insurable, or both”
( v0 j4 I; r7 K; u1 i5 c“ruling”是什么意思啊？

谢谢各位啦！
