Employer Tax Mistake

I am asking for advice for a family member who has found themself in the situation where they have just discovered that their employer may have binned their P45 when they changed job in Jun of 05 and consequently they have been paying incorrect tax for the last 6mths. Even after asking, the employer cannot answer what happened. The P45 may have been binned or the wrong parts may have been sent of to the revenue but now my family members may owe approx €1200 in unpaid tax. Is it not an employers responsibility to deduct tax from an employees salary both PAYE and PRSI and remit this to the revenue? Surely if they fail to do this the employee should not be held responsible for their gross mistake even after sumbitting all the documents that they were required to do so.

Can anyone offer any advice as to where my family member stands and what they should do from here?
Thanks in advance

AFAIK each persons' tax affairs are their own responsibility and the onus is on them to ensure that their tax is in order. So I am afraid it is up to your family member to get the issue resolved including backpaying any unpaid taxes.
