The North Carolina Department of Revenue issues a business a single state tax identification number to cover employee income tax withholding, sales tax, and the state's machinery, equipment, and manufacturing use tax. Getting a North Carolina state tax ID number is a quick process. Numbers are often assigned immediately after submission of an online application form, although in some cases, the process can take up to 10 working days.
Get a federal employer identification number (EIN). Before applying for a North Carolina state tax ID number, your business must have a federal EIN or taxpayer identification number. The online application is free at http://www.IRS.gov/businesses/small/article/0,,id=98350,00.html.
File your corporate documents with the North Carolina Secretary of State office. Before registering for a state tax ID number, corporations must be on file with the Secretary of State office and have received a registration number. Contact the Corporations Division at 919-807-2225 or see http://www.secretary.state.nc.us/corporations/thepage.aspx for details. Other business forms, such as sole proprietorships, LLCs, and partnerships do not need to file with the Secretary of State.
