The excess business loss rules may limit how much of a business loss reported on IRS Schedule C can be applied against other income in a given tax year. These rules affect how Schedule C losses are treated within the individual income tax return after the form is completed.
What Excess Business Loss Rules Are
The excess business loss framework restricts the amount of aggregate business losses that an individual can use in a single year. Loss amounts above the applicable threshold may be disallowed for the current year and carried forward under separate rules.
How Excess Business Loss Rules Relate to Schedule C
Schedule C determines the net profit or net loss from a business activity, but it does not apply the excess business loss limitation itself. Instead, the reported result is later evaluated under the excess business loss rules as part of the overall tax return.
Interaction With Other Loss Limitation Rules
The excess business loss rules operate alongside passive activity limits and at-risk rules. Together, these frameworks determine how reported Schedule C losses are treated within the tax system. Overviews of related rules are provided in Passive Activity Limits and At-Risk Rules.
Connection to Profit and Loss Reporting
Understanding how profit or loss is calculated on Schedule C helps clarify when excess business loss rules may become relevant. How profit and loss are determined is explained in Understanding Profit and Loss.
