单位要身份证明说是给税务局，有没有朋友知道怎么回事

单位要身份证明说是给税务局，有没有朋友知道怎么回事。我没身份会不会被查？谢谢

it depends on what company you are in and which department is requesting the document for... Once requested by HR department, it is very likely to be an immigration check routine. If requested by Finance department or payroll, I think you would be generally ok.
