<< + 17% or so matching SS >>
Employer match is 7.65% including Medicare.
<< + 4-5% payroll for unemployment >>
Unemployment insurance varies from state to state. Most are about 1.5% of wages earned. In some states, the employee picks up part of the tab.
<< + $50-$200 workmans comp per employee (today's market is hard to tell) >>
Workers comp insurance in most states is based on a sum per hour worked. For example, it might be 30 cents per hour. The base figure will vary based on industry classification and be adjusted based on claims history. As a new employer, you get hit on the high end for your industry. In many states, you are allowed to deduct a small portion of this from the employees paycheck to offset the cost.
<< Your liability insurance may go up assuming the employee will increase your gross output. >>
This would have little or no impact on liability insurance.
<< But if you are the owner and he/she is your only employee, I don't think you have to get workmans comp for him/her. >>
There is no state that I know of that does not require worker's comp insurance, even if it is only one employee.
<< A good insurance policy for you would be good though, just incase something happens. >>
The cost of self-insuring or purchasing a private plan for worker's comp is prohibitive for most small employers. In addition, many states have VERY stringent financial criteria you must meet before they will let you do it. Some, called "monopolistic insurance" states won't let you do it at all.
