Why am I asked to set my turnover slab?

1. GST rules change at ₹5 Cr of previous-FY turnover: above it, 6-digit HSN codes are mandatory even on B2C rows; below it, B2C HSN is optional. AprilTax can't apply the right checks until you declare which side you're on.

2. Click the inline slab picker right on the failing check card - one click sets it.

3. You can also set it any time from the business header (next to your GSTIN) - the declaration is FY-aware, so it carries forward each year.

4. Click Re-run checks - the check clears instantly.
