For tax years beginning on or after January 1, 2015 New Jersey has amended the Corporation Business Tax Code to require paid tax practitioners who prepare returns for partnerships to file partnership returns (Form NJ-1065) by electronic means. Payments of corporation business tax liabilities, including estimated payments, extensions and vouchers must also be made electronically whether remitted directly by the taxpayer or by the tax preparer. Returns for partnerships that are not prepared by paid preparers must be filed electronically only if they have ten or more partners. For partnerships with fifty partners or less, the Division provides a free online partnership filing. For tax years beginning on or after January 1, 2016, taxpayers who submit their own returns must file their corporation business tax returns electronically. Failure to comply with the electronic filing rule may result in a penalty. For more information, go to: https://www.state.nj.us/treasury/taxation/efilemandatepartner.shtml
