Over the Christmas period of last year I did some seasonal temporary work at my previous employer (who I had left a few months prior due to education commitments), but due to multiple failures (mine, the employer's, and the income tax office) I was improperly taxed for the month of December.
My previous employer told me that they are unable to repay the income tax deducted as I am no longer on payroll, while the income tax office told me that they are able to refund me but not until my previous employer had sent in their income tax statement for the first quarter of 2018, due by a certain date at the beginning of April.
That date has passed. The income tax office contacted me today apologizing and said that my previous employer has yet to send in their income tax statement for the last quarter. I am still owed the income tax that was incorrectly deducted. I cannot note it in my income tax return because as a student, I do not complete income tax returns.
Is it ethical for me to contact my previous employer to ask them about the state of their income tax return for last quarter? I do not want to burn bridges but at the same time, I want to be repaid the money that I am owed.
