What Is the CBT-100 Corporation Business Tax Return?

The CBT-100 is the official New Jersey Corporation Business Tax Return used to report annual income and calculate state tax liability. All corporations operating in New Jersey or earning income from New Jersey sources must file it each tax year.

Who Must File This Form

Any domestic or foreign corporation with a taxable status in New Jersey must file this return annually. Investment companies and professional corporations follow separate schedules within the same return. Non-corporate businesses use different forms, such as the Unincorporated Business Tax Return.

How to Complete the Corporation Tax Return

Enter your corporation name, federal employer identification number (FEIN), and New Jersey tax ID at the top of the form. Complete Schedule A to calculate allocated net income, Schedule A-2 for subsidiary details, and Schedule A-3 for adjustments. Calculate the corporation tax on allocated net income, then apply any estimated tax payments already submitted. If additional tax is owed, attach the payment voucher. To request a filing extension, submit the CBT-200-T form before the original return due date.

Is Electronic Filing Required?

Yes. New Jersey requires all corporation business tax returns and payments to be submitted electronically through the Division of Taxation portal. Paper returns are no longer accepted for this form.
