Does New Jersey require state 1099 tax filing?
Yes, New Jersey requires all 1099 forms to be filed with the New Jersey Department of the Treasury.
Does New Jersey participate in Combined Federal/State Filing?
Yes, New Jersey participates in Combined Federal/State Filing. If you utilize CF/SF when filing your 1099s, the IRS will forward the information to the New Jersey Department of the Treasury and you will not have to do so yourself.
However, if there was voluntary tax withheld or if payments made exceed the $1000 threshold, then the forms must be filed directly with the state of New Jersey, even if you participate in the CF/SF program.
