All property, except as hereinafter provided, shall be taxed. All taxes shall be levied and collected under general laws and shall be uniform upon the same class of subjects within the territorial limits of the authority levying the tax, except that the General Assembly may provide for differences in the rate of taxation to be imposed upon real estate by a city or town within all or parts of areas added to its territorial limits, or by a new unit of general government, within its area, created by or encompassing two or more, or parts of two or more, existing units of general government. Such differences in the rate of taxation shall bear a reasonable relationship to differences between nonrevenue-producing governmental services giving land urban character which are furnished in one or several areas in contrast to the services furnished in other areas of such unit of government.

The General Assembly may by general law and within such restrictions and upon such conditions as may be prescribed authorize the governing body of any county, city, town or regional government to provide for differences in the rate of taxation imposed upon tangible personal property owned by persons not less than sixty-five years of age or persons permanently and totally disabled as established by general law who are deemed by the General Assembly to be bearing an extraordinary tax burden on said tangible personal property in relation to their income and financial worth.

The General Assembly may define and classify taxable subjects. Except as to classes of property herein expressly segregated for either State or local taxation, the General Assembly may segregate the several classes of property so as to specify and determine upon what subjects State taxes, and upon what subjects local taxes, may be levied.
