I have been advised that due to my employer failing to withhold sufficient PAYG, I have been left with a Taxation bill of $6000. As in previous years, I had varied my tax. I did at the end of the last financial year write to my employer to confirm that the variation they had had and end date and so I should be paying normal PAYG. I received a reply confirming that the correct rate was now being applied. This obviously was totally wrong and now I am left with a $6000 debt. I again wrote to my employer and ask how this happened and what they were going to do about it. No reply has been forthcoming. Do I have any options?
