Your accountant is probably right, as you are probably paying PRSI at the S class, which does not qualify for statutory redundancy.
However, you may be entitled to tax free Termination payments, (If you google "Directors termination payments" you should find a very helpful briefing note from the Revenue Commissioners.)
You accountant should be advising you on other tax efficient cash extraction procedures, such as Pensions and Members Voluntary Liquidations. In a MVL you may able to avail of early retirement relief. An MVL would also mean that the company would be liquidated, and thereby you would save the expense of a strike off.
