Risk Radar
Scan points- 1Ensure Line 16 is a negative amount; otherwise, it is not recorded as the excess business loss.
- 2Failing to add back capital gains not attributable to trade or business on Line 10.
- 3Not remembering that an excess business loss reported on Line 16 is entered as a positive number on the return.
- 4Omitting the required line references when filing returns other than Form 1040/1040-SR.
- 5Using the wrong threshold amounts: $313,000 (single) or $626,000 (joint).
Plain English
This form tells the IRS how much of your business loss you are allowed to deduct in the current tax year. If you have more than what is allowed, this form calculates the excess amount, which then becomes a Net Operating Loss (NOL) carryover for future years.

What this form is for
- Use this form when a noncorporate taxpayer (including a trust subject to tax under section 511) has net losses from trades or businesses exceeding $313,000 (or $626,000 if filing jointly), or if a loss on any single line (1 through 8) exceeds $156,500.

The threshold amount is $313,000 for a single taxpayer and $626,000 for taxpayers filing a joint return.

How do capital gains/losses affect the calculation?

→ Check 'Treatment of capital gains and losses' on page 1.
