If you run a business as a sole proprietorship and have an operating loss, you can normally deduct this loss from your other sources of income. If your business loss is large enough to wipe out all other income sources, it is called a Net Operating Loss (NOL). If you have a NOL you can carry this loss to another year and use it as a deduction to reduce that year's taxable income. This calculator helps you calculate your NOL deduction and any remaining NOL that you may carry to another year.
