<h1>Businesses with turnover over 5 crores must report six-digit HSN codes for supplies per Notification 78/2020 Central Tax.</h1> Taxpayers with an annual aggregate turnover exceeding 5 crores are now required to report a minimum of six-digit valid HSN codes for outward supplies, following notification no. 78/2020 Central Tax. This mandate, already integrated into the GST system, is being extended to the IRPs portal in collaboration with partners like NIC. If a valid six-digit code is unavailable, an eight-digit code should be used. The GSTN team acknowledges potential system adjustments needed by taxpayers and will provide ample time for compliance, with the implementation date to be announced soon.
