an NOL applies at the taxpayer level, not the various items that make up the line items on the tax return which would include the reporting for a single member LLC.
example
example
taxable wage W-2 $50,400
loss schedule c - single member LLC -55,000
nonbusiness income 13,400
standard deduction - single -12,400
taxable income -3600
NOL is 3600
an individual's NOL should be computed using schedule A on form 1045
the short version is an NOL is the excess of business losses over business income reduced by the excess, if any, of nonbusiness income over nonbusiness deductions
business income w-2 $50,400 business losses schedule c -$55,000 net loss -$4600. but this is not your NOL because the nonbusiness income of $13,400 exceeds the nonbusiness deductions - the standard deduction of $12,400 by $1000 so the $4600 business loss is reduced by $1000 the excess nonbusiness income to arrive at your NOL of $3600.
while in this example the NOL was the same as taxable income this may not always be the case.
