澳洲PR触犯了税法对身份有什么影响？

PR犯法照样可被遣返或驱逐出澳大利亚的

Permanent residents liable to deportation and removal
7.15 Although the focus of the previous section was on removal of temporary visa
holders, it is apparent that the power of cancellation under s.501 also extends to permanent
residents, and may be exercised even where a person becomes liable to deportation.9 It is,
therefore, possible to cancel the permanent visas of non-citizens convicted of crimes in
Australia and to have such persons removed, rather than deported, from the country.
Furthermore, as the cancellation power is not limited by the time a non-citizen has spent in
Australia, criminals who can no longer be deported because of the ten year rule remain
subject to visa cancellation and removal unless they obtain citizenship.10

当然，触犯税法会不会严重到取消PR签证就不得而知了

放心，只要你的PR身份已经批准了，移民局没权利取消你的身份，只是在入籍的时候有可能，但根据你说的情况，责任在雇主那边，一般来说不会有太大的问题，PR期间如果涉及到触犯比较严重的刑事犯罪才有可能会影响到现有的身份，甚至会被遣返回国，因为你只是PR，国籍依旧没变，不属于澳洲公民。

PR是可能被取消的。移民局有权利取消。因为并不是公民。取消后会遣返回国。当然酌情而定，也可能逃税只是罚款而已。
