You can do this in a few ways, depending on what exactly you want to do:

1. Using period reporting feature (`-p`):

   hledger bse -p "yearly from 2019-04" --depth=2 --layout=bare -e 2022-04-01 -X₹

2. Separating journals into April 1 – March 31 financial years.

3. Using `-b` and `-e` to demarcate begin and end dates when generating reports.
