Dear SivaRama Kumar,
1. Ineligible ITC shown in Table 4D of GSTR 3B will not have any impact on "Electronic credit ledger". It is just a disclosure part. Only 4A and 4B will impact "Electronic credit ledger".
2. Coming to ITC comparison with 2A, Portal is giving facility "ITC credit claimed and due" wherein it is adding values in 4A with 4D and then comparing with 2A.
3. In my view, in order to get correct reconciliation with 2A and correct values in electronic credit ledger, ineligible credit has to be included in Table 4A (5), deducted from 4B and then disclosed in Table 4D. This will give correct disclosure in "Electronic credit ledger" and proper reconciliation with 2A aswell.
