Successor liability for tax: successors or estates remain responsible for tax, interest and penalty up to the change in status. Continuing and successor liability is imposed for tax, interest and penalty where the taxable person dies, a HUF or association is partitioned, a firm is dissolved, or guardianship/trust terminates, with successors or estate representatives liable for amounts due up to the date of change; liabilities apply whether determined before or after the change, subject to the Insolvency and Bankruptcy Code exception.
