W. Va. Code § 11-13J-9
If it appears upon audit or otherwise that an eligible taxpayer has not made contribution as represented, or should it appear that contributions made by an eligible taxpayer were made to the direct or indirect benefit of the eligible taxpayer making the contribution or to the direct or indirect benefit of any person related to the eligible taxpayer making the contribution, the credit previously allowed under this article shall be recaptured, and amended returns shall be filed for any tax year for which the credit was taken. Any additional taxes due under this chapter shall be remitted with the amended return or returns filed with the tax commissioner, along with interest, as provided in section seventeen, article ten of this chapter, and a ten percent penalty, which may be waived by the tax commissioner if the taxpayer shows that the overclaimed amount was due to reasonable cause and not due to willful neglect, and such other penalties and additions to tax as may be applicable pursuant to the provisions of article ten of this chapter. Notwithstanding the provisions of article ten of this chapter, the statute of limitations for the issuance of an assessment of tax by the tax commissioner shall be five years from the date of the filing of any tax return on which this credit was taken or five years from the date of payment of any tax liability calculated pursuant to the assertion of this credit, whichever is later.
