A school district tax is not a municipal tax. School district tax should not be reported on a RITA return. School district taxes (while they may be reported in box 19 and 20 of your W-2) are not municipal taxes. Most W-2 forms do not have enough space to report school district tax on a separate line or box item; therefore these taxes are often reported in the local tax section on a W-2. See W-2 Example 1A.
Any four digit code (such as 2509) that appears before or after the designation SD, LSD, or CSD in box 20 on a W-2 indicates that the amount reported to the left of that code (in box 19) is a school district tax and it should not be reported on a RITA return. See W-2 Example 1A.
