For partners and shareholders who opt out of the composite filing, the partnership or S corporation must remit the withholding on Indiana distributions into a nonresident withholding account.
Nevertheless, partnerships still file an annual tax return, Form 1065. A partnership can file an amended return using Form 1065X within three years of the date it filed the original return, or three years of the due date, whichever is later. In addition to filing the amended return, the company must also provide the IRS updated versions of Schedule K-1, the forms that describe each partner's share of the company's profits, losses and deductions.
