Q. Do you also sign these separately from main return?
A. No. Do not sign or submit the SD100
Q. These new pages may be due to a question I answered wrong, but in the HELP area it said IF you see numbers in certain boxes of your W2 you likely need to answer yes. So I did.
A. Boxes 18-20 of your W-2 are used for both School District (SD) and City income tax. If you work in a city with an income tax, your employer must withhold tax and fill those boxes. But, you don't file a city (or SD) tax return unless you live in a city with a tax.
