Your property tax rate will be based on the assessed value of your real estate. Be aware that in many areas, commercial and industrial property is assessed at a higher level than residential property. If you believe your tax assessment is too high, you might want to consult with your attorney to file a request for a new assessment.
In addition, you might also be liable for "personal property taxes" on the estimated value of other property your company owns, such as inventory, furniture and fixtures, automobiles and trucks, research equipment, etc.
