According to our accountant as work, the strict definition of tax law is that expenses must be taxed and you claim them back at the end of the year.
Revenue can and do give employers permission to give untaxed expenses, in certain circumstances. Its fairly normal for this to happen, I have never heard of anyone being taxed on their expenses. however, Revenue do make sure that companies are not using expenses to pay people under the table and avoid tax.
I dont know if your company are unaware of this, or have not been given or have not asked for permission to give you untaxed expenses.
If you ask your accoutant at work why they will not or cannot give you your expenses untaxed. Also contact you local Revenue office and ask them.
I am only guessing, but could it be, that 50 miles away of not far enough away for Revenue to consider it legitimate expenses ?
