Application of retained assets: retained assets may be applied to outstanding wealth tax liabilities and surplus returned to custodian. Retained assets under section 37A may be applied to discharge existing and assessed wealth-tax liabilities (including penalties and interest); money retained may be used first and non-cash assets may be deemed under distraint and sold under Income-tax Act procedures to recover outstanding liabilities. Other recovery modes remain available. Any surplus assets or proceeds after liabilities are met must be returned to the custodians. The Central Government must pay simple interest on the excess of retained amounts and sale proceeds over liabilities, running from the date after a six-month period following the relevant order to the date of assessment or reassessment.
