“The obligation to file a correct tax return is on the taxpayer, and the taxpayer cannot transfer that obligation. If the Appellant relies on an accountant to prepare and file a tax return on his behalf, then the Appellant will be responsible if errors in the tax return are due to negligence by the accountant acting on his behalf.… If there has been negligence on the part of an accountant, it may be that the taxpayer may have some recourse against the accountant. However, that does not normally affect the liability of the taxpayer to a penalty for filing an incorrect return.”
