. (a) If an escape assessment is made as a result of an audit that discloses that property assessed to the party audited has been incorrectly assessed either for a past tax year for which taxes have been paid and a claim for refund is not barred by Section 5097 or for any tax year for which the taxes are unpaid, the tax refunds resulting from the incorrect assessments shall be an offset against proposed tax liabilities, including accumulated penalties and interest, resulting from escaped assessments for any tax year covered by the audit.
