<h1>GSTR-3B Table 3.2 auto-populated values become non-editable; correct via GSTR-1A amendments for the same period.</h1> From the November 2025 tax period, values auto-populated into Table 3.2 of Form GSTR-3B-reflecting inter state supplies to unregistered persons, composition taxpayers, and UIN holders from GSTR-1, GSTR-1A, and IFF-will be non-editable; corrections must be made by amending the underlying data via Form GSTR-1A for the same tax period (or through subsequent GSTR-1/IFF filings), which will instantly update Table 3.2 and allow filing of GSTR-3B with corrected values.
