The New Jersey Legislature originally incorporated Orange as a township on November 27, 1806, from parts of Newark Township. Parts of the township were taken on April 14, 1834, to form the now-defunct Clinton Township. On January 31, 1860, Orange was reincorporated as a town. Parts of the town were taken to form South Orange Township (April 1, 1861, now known as Maplewood), Fairmount (March 11, 1862, now part of West Orange), East Orange Township (March 4, 1863) and West Orange Township (April 10, 1863). On April 3, 1872, Orange was reincorporated as a city.[21] In 1982, the city was one of four Essex County municipalities to pass a referendum to become a township, joining 11 municipalities that had already made the change, of what ultimately were more than a dozen Essex County municipalities to reclassify themselves as townships to take advantage of federal revenue sharing policies that allocated townships a greater share of government aid to municipalities on a per capita basis.[22][23][24][25][26] The city derives its name from William III of England[27] or William IV, Prince of Orange.[28]
In 2020, the township had New Jersey's 12th-highest property tax rate, with an equalized rate of 4.679% compared to 2.824% in the county as a whole and a statewide average of 2.279%.[30]

"In 1978, South Orange Village was the first municipality to change its name to the 'township' of South Orange Village effective beginning in entitlement period 10 (October 1978 to September 1979). The Borough of Fairfield in 1978 changed its designation by a majority vote of the electorate and became the 'Township of Fairfield' effective beginning entitlement period 11 (October 1979 to September 1980).... However, the Revenue Sharing Act was not changed and the actions taken by South Orange and Fairfield prompted the Town of Montclair and West Orange to change their designation by referendum in the November 4, 1980, election. The municipalities of Belleville, Verona, Bloomfield, Nutley, Essex Fells, Caldwell, and West Caldwell have since changed their classification from municipality to a township."

"Under the Federal system, New Jersey's portion of the revenue sharing funds is disbursed among the 21 counties to create three 'money pools.' One is for county governments, one for 'places' and a third for townships. By making the change, a community can use the 'township advantage' to get away from the category containing areas with low per capita incomes."

"Signs on Interstate 280 often lump the township into a region known as "the Oranges," with Orange, East Orange and West Orange. But South Orange has a decidedly different feel: less urban than Orange and East Orange, but less spread out than West Orange."
