Any provision for tax payment by installments after 143(3)

Yes you can do so but only with the permission from you AO. You will be levied with extra interest also on the balance amount also. You need to meet your AO at the earliest

Keep your fingers crossed and hope for he best. Provide him with reasons for the delay in payment of demand order.

Also take the help of a CA to handle it better
