Table 12 doesn't match my sales totals - what do I do?

1. This check compares your HSN summary (Table 12) against the sales in Tables 4-11 - taxable value and tax must tie back exactly.

2. First, simply regenerate the return - Table 12 is rebuilt from the latest invoice data, which clears most mismatches (a stale summary after new uploads is the usual cause).

3. If it persists, check whether an HSN row was hand-edited in the Amendment HSN & Rate modal with a rate that doesn't match the underlying invoices - undo or correct that edit.

4. Re-run checks to confirm the totals now tie.
