Corporate Income Tax

If your business is incorporated in West Virginia or does business or participates in certain other activities in West Virginia, you may have to file an annual West Virginia State Corporation tax return.

The Corporation Net Income Tax is a tax on the West Virginia taxable income of every domestic or foreign corporation which enjoys the benefits and protections of the government and laws in the State of West Virginia or derives income from property, activity or other sources in West Virginia.

Extension of Time to File

An extension of time to file a Federal Return is automatically accepted by West Virginia as an extension of time to file the West Virginia return.

A copy of Federal extension form (Federal Form 7004) must be attached to the West Virginia return when filed and the extended due date must be entered on top of the first page of the West Virginia State Tax Return.

A state extension of time to file may be obtained, even if a federal extension has not been requested, provided a written request is made to the West Virginia Tax Department prior to the due date of the return.

An extension of time to file does not extend the time for payment of tax due. If you have an extension of time to file, payment of any tax due may be made by filing a tentative return. (See the instructions for Form CNF-120EXT ).

To avoid interest and penalties, payment must be received on or before the original due date of return.

Additions to Tax

Late Filing

Additions to tax are imposed for failure to file return on or before the due date (determined with regard to an extension to file).

On any amount of tax shown to be on the return, the additions to tax for late filing is five percent (.05) per month or any part of a month, not to exceed twenty five percent (.25).

Late Payment

Additions to tax are imposed for failure to pay all tax shown to be due on a return on or before the due date (determined without regard to an extension of time to file).

The additions to tax for late payment are imposed at the rate of one half of one percent (.005) per month or part of a month not to exceed twenty five percent (.25).

Late File and Late Pay

When both the five percent (.05) additions to tax for late filing and the one half of one percent (.005) additions to tax for late payment are imposed, the maximum monthly percent is five percent (.05) not to exceed forty-seven and one half of one percent (.475) of the tax due.

Failure to Pay Estimated Tax

Corporations that are required to make estimated payments of their tax liability are subject to additions to tax for failing to pay at least ninety percent (.90) of their annual tax liability.

The additions are imposed at the same rate as interest is imposed. See form CNF-120U for more information.

Completion and Signature

All applicable sections of the return must be completed and all required supporting documents must be attached. An incomplete return will not be accepted as timely filed.

The return must be signed by an authorized officer. If the return is prepared by someone other than the taxpayer, the preparer must also sign the return and enter his or her complete address.

Changes on Federal Return

Any corporations whose reported income or deductions are changed or corrected by the Internal Revenue Service are required to report the change or correction to the West Virginia State Tax Department.

This report must be made within 90 days of the final determination by filing an amended return and attaching a copy of the revenue agent’s report detailing such adjustments.
