Can a taxpayer generate challan in multiple sittings?

Yes, a taxpayer can partially fill in the challan form and
temporarily “save” the challan for completion at a later stage.
A saved challan can be “edited” before finalization. After
the tax payer has finalized the challan, he will generate the
challan, for use of payment of taxes. The remitter will have
option of printing the challan for his record.
