you need to figure out what you have or perhaps you need to consult a tax professional. if you have an S-Corp that is required to file a return, the failure can result in penalties of about $2,500 for each full year late for each year you failed to file. If your law firm is the S-Corp there can be additional IRS/state penalties - failure to take a salary, failure to withhold taxes, failure to remit taxes, failure to file payroll tax returns, failure to have a workmen's compensation insurance policy - you are an employee of the S-Corp
