(a) For taxable years beginning on and after January 1, 2007, in addition to amounts authorized to be subtracted from federal adjusted gross income pursuant to subsection (c), section twelve of this article, any payment during the taxable year for amounts expended by an individual for tolls paid electronically through use of a West Virginia Parkways, Economic Development and Tourism Authority PAC card (parkways authority commuter card) account for noncommercial commuter passes for travel on toll roads in West Virginia, not including amounts paid as refundable transponder deposits or amounts reimbursed by an employer or otherwise, is an authorized modification reducing federal adjusted gross income, but only to the extent the amount is not allowable as a deduction when arriving at the taxpayer's federal adjusted gross income for the taxable year in which the payment is made. In the case of a single person, a head of household or a married couple filing a joint return, or a married person filing a separate return, this authorized modification reducing federal adjusted gross income shall apply only to the portion of the expended amount that equals or exceeds $25 and the total amount deducted for a taxable year shall not exceed $1,200. Any amount of qualified tolls paid and eligible for this decreasing modification and not used in the taxable year when paid shall carry forward for up to three taxable years subsequent to the taxable year when paid. Qualified toll payments not used by the end of the carry forward period shall be forfeited.

(b) The Tax Commissioner annually, on or before December 31, of each calendar year, beginning in 2008, shall certify to the West Virginia Parkways, Economic Development and Tourism Authority: (i) The total dollar amount of tolls deducted by individuals under this section on personal income tax returns filed for the preceding taxable year beginning with taxable year 2007; and (ii) the total dollar amount of personal income tax revenue not collected through the date of such certification solely as a result of such total toll deductions for such taxable year.

(c) On or before June 30 of the following calendar year, beginning in 2009, the West Virginia Parkways, Economic Development and Tourism Authority shall pay to the Tax Commissioner an amount equal to such certified total dollar amount of personal income tax revenue not collected for the taxable year covered by such certification: Provided, That the authority shall make such payment solely from nontoll revenues (that is, from revenues derived by the authority from sources other than tolls charged for transit on the West Virginia Turnpike) and only at such times and in such amounts and installment payments as are permitted by covenants and agreements of the authority under such bond indentures and other bond agreements as are then applicable to such nontoll revenues: Provided, however, That to the extent required to comply with such bond indentures and other bond agreements, the authority may defer the payment of all or a part of such amount beyond June 30 of the following calendar year.
