Commissioners are scheduled to decide Thursday night whether to pose a referendum question on the tax's future on the November ballot.
The library tax, which amounts to 0.06087 mills, allows residents to utilize the Allentown Public Library or any other local library.
If the levy is lifted, those who want to use out-of-town library services would have to pay for it out of pocket. Salisbury Township does not have a public library.
The township library tax system began in 1993.
The township pays $81,559 from the tax collected for citizens to utilize libraries in other jurisdictions, mainly Allentown.
Any change to the current township library policy would not occur until Jan. 1, 2015.
Commissioners must first pass a resolution to place a referendum on November's ballot. The Allentown library must be notified of the change by April 1, 2014 and the library levy would end at the beginning of 2015.
