IRS Schedule B (Form 1120-S): Ownership, Accounting Methods & Other Information

What is IRS Schedule B (Form 1120-S)?

IRS Schedule B (Form 1120-S) is an information schedule that accompanies Form 1120-S. It asks a series of questions about your S corporation's ownership, tax status, financial activities, and filing obligations. Your answers help the IRS determine whether additional forms, disclosures, or reporting requirements apply to your corporation

How Schedule B Differs From Other Schedules

Who Must Complete Schedule B?

Every S corporation filing Form 1120-S must complete Schedule B if they:

• Have total assets of $250,000 or more at the end of the tax year, or
• Report balance sheet data on Schedule L, or
• Have foreign transactions, shareholder loans, or related-party activities.

If your corporation has total receipts and assets under $250,000, you may be exempt from completing Schedule L and certain parts of Schedule B, but you must still disclose relevant ownership and accounting method details on Schedule B.

Filing Deadlines

Schedule B must be filed alongside Form 1120-S by the S corporation’s tax filing deadline.
