You are required to pay estimated income tax if the tax shown due on your return, reduced by your North Carolina tax withheld and allowable tax credits, is $1,000 or more regardless of the amount of income you have that is not subject to withholding. Each payment of estimated tax must be accompanied by Form NC-40, North Carolina Individual Estimated Income Tax. If you are filing estimated tax for the first time, contact any of our offices so that appropriate forms can be mailed to you. You can also pay your estimated tax online at www.dornc.com, search for online file and pay.
You should prepare your estimated tax carefully, both to avoid having to pay a large amount of tax when you file your return, and to avoid owing interest for underpayment of estimated income tax. Payment of estimated tax does not relieve you of your responsibility for filing a return if one is due.
