Determining NOL Amount. If your business expenses are more than your business income, you may have a net operating loss (NOL) for the year. However, simply having a negative amount on the taxable income line on your income tax return is not a guarantee that you actually have a net operating loss.f you have a net operating loss from your sole proprietorship, you'll normally be able to deduct the loss from your total income from other business ventures or from any salary, wages, or other earnings.
1 Income Tax Returns (Please keep in mind that you can be audited by the IRS for no reason up to three years after you filed a tax return. 2  If you omit 25% of your gross income that goes up to 6 years and if you don't file a tax return at all, there is no statute of limitations.). Paycheck Stubs (You can get rid of once you have compared to your W2 & annual social security statement). 2  Utility Bills (You can throw out after one year, unless you're using these as a deduction like a home office --then you need to keep them for 3 years after you've filed that tax return).
