definitely get the help of a professional. not only are you facing penalties for late filing of the S-Corp return but there are also substantial penalties for late filing and late payment of medicare, social security, withholding (form 941), unemployment taxes (form 940 ), form w-2 and W-3. form 944 isn't filed unless the IRS told you to do so.
you also have to file state UC forms and possibly payroll tax forms which most likely are also late meaning more penalties and interest.
