Sounds like your employer may be at fault, by either not sending in the required paperwork to the SSA and IRS (or doing so late) and/or failing to remit the taxes withheld from your pay to the IRS. If so, it could be sloppy bookkeeping, incompetence, or even outright fraud. Do any of your coworkers have a similar problem?
I don't necessarily see an issue with the accountants here. They can only work with what they are given. You may wish to see an attorney.
