The Indiana Department of Revenue has a new withholding XML schema to service WH-1 and WH-3 filings.
Effective January 1, 2017, this schema must be used for all filing years.
ERF is unavailable from December 31, 2016 at noon to January 1, 2017 at noon. The old schema may be used to submit WH-1 and WH-3 filings until 11:45 a.m. on December 31, 2016.
