(AP) -- All construction contractors need to make sure they are registered with the Nebraska Department of Revenue, so they won't have part of their payments withheld next year. A new rule requiring contractors to register with the department takes effect Jan. 1. The law requires contractors to withhold 5% of the payment owed to any subcontractor if the subcontractor is not part of the Revenue Department's database. The money withheld will go to the state and be treated as income tax withholding. If the subcontractor doesn't end up owing the full 5% in income taxes, it can recover money, but not until it files its tax return for the year. For more information, go to www.revenue.ne.gov.
