The department may accept a signed attestation in a form and manner determined by the department from an individual to presumptively validate that an individual meets all the eligibility requirements as provided in this section. The signed attestation is subject to audit verification by the department to validate an individual's eligibility for the working families' tax credit.

The department may also assess such overpaid amount against the individual's spouse if the refund in question was based on both spouses filing a joint federal income tax return for the year for which the refund was claimed.
