| The cost of filing your tax return would be the most significant cost in my opinion but this may vary depending from State to State and your relationship to your CPA. However, it may range from $450 to $750.
The cost of an annual report may be as high as $50 such as in New Jersey.
It seems that you have filed to be treated as an S corporation, which is why I suspect that you are taking a salary. This would subject you to the minimum S Corporation tax that is applicable to your particular state, for instance in New Jersey State it is currently $520. |
