Troubleshooting
Gateway of Tally → Import → Vouchers is strict about what it accepts. Here are the errors that come up most often, and what actually causes each one.
Prevention
Most of these errors trace back to one of two habits: importing before every referenced ledger exists, or importing the same period twice without checking first. Before any XML import, it's worth creating (or confirming) the bank ledger and a Suspense ledger, checking Gateway of Tally → F11 for the active financial year against the statement's date range, and keeping a simple log of which statement periods have already been imported for each company. None of that is Tally-specific caution — it's the same discipline any bulk data import needs, accounting software or not.
When the error isn't listed here
Tally's import log is usually specific about which voucher failed and why, even when the wording is terse. If an error doesn't match anything above, the log entry itself — not a general troubleshooting guide — is the fastest way to the actual cause. If the XML came from bank2tally and something looks wrong in it, the file is plain text; opening it in a text editor to check the voucher in question usually clarifies whether the issue is in the file or in Tally's current company setup.
Questions
Tally's XML import never creates ledgers automatically — every ledger name in the file must already exist in the company, spelled exactly the same way, before you import.
Yes. Tally does not check whether a voucher was already imported, so re-importing the same file creates a second, duplicate set of vouchers.
No — every voucher it produces has an equal debit and credit leg by construction. An unbalanced-voucher error points to a hand-edited or different tool's XML file.
