What is at-risk limitation?

The at-risk limitation restricts business loss deductions to the amount the taxpayer has at risk in the activity, generally including cash invested and personal liability on debt, preventing deductions for losses exceeding actual economic investment. For professional service firm owners, at-risk rules limit loss deductions to actual economic exposure.

Key characteristics

• Limits loss deductions

Why it matters for professional service firms

You cannot deduct losses exceeding your actual economic investment. At-risk tracking ensures deductions reflect real economic exposure. Professional service firm owners with business losses should verify sufficient at-risk basis before claiming deductions.

Real-world example

Amanda invested $50,000 in a partnership, generating a $72,000 loss. At-risk amount: $50,000 (her cash investment). At-risk limitation: can only deduct $50,000 loss currently, $22,000 suspended. Suspended loss is carried forward until an additional at-risk amount exists (more investment or income allocation). Loss deduction limited to actual economic stake.
