What Schedule K-1 100S reports
Schedule K-1 100S is the shareholder statement used by an S corporation to report each shareholder’s allocated share of income, deductions, credits, and other tax items. The shareholder uses those amounts when preparing the applicable individual tax return. The corporation prepares the statement from its tax records and provides it to the shareholder. signNow can hold the prepared PDF, route it for acknowledgment or signature, and preserve the signed copy with an audit trail. IRS retention rules apply to the underlying tax records under IRC §6501(a), with longer periods for substantial understatement, fraud, or no return.
