RE: Single and Double Random Lenght of Pipes. OrangeDog70 (Mechanical) 3 Aug 04 14:33. DRL and SRL pipe have to do with the length of the pipe stalks and not diameter or wall thickness. This is usually important for the transportation of the pipe from the mills to the suppliers or to the jobsites.
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.
For example, a single person under age 65 with less than $9,500 in gross income to report did not have to file a return for the 2011 tax year. Also, you do not owe any self-employment tax if your business did not earn at least $400 in net income.ou may deduct expenses as well as revenues on Schedule C to arrive at net income. Even if your business did not have net income to report, you still may owe taxes on income you earned from other sources, such as a job, investments or rental properties.
