any one pls help explain 245 section

245. Where under any of the provisions of this Act, a refund is found to be due to any person, the Assessing Officer, may, in lieu of payment of the refund, set off the amount to be refunded or any part of that amount, against the sum, if any, remaining payable under this Act by the person to whom the refund is due, after giving an intimation in writing to such person of the action proposed to be taken under this section.

The above is self explanatory.
