SAT paid with a Error in quoting PAN No. URGENT

NO

TDS deducted under wrong pan number would not be eligible to get credit, you have to ask your deductor to revise return immediately

The credit for SAT is not given because the PAN quoted is wrong any tax paid or dedcuted is reflected in the Form AS-26 of NSDL. The SAT might not being reflected in the Form and hence the Intimation is been given with a demand of Rs. 12000 + interest

The Letter which you have filed with the AO is a valid proof of your's intending to rectify the mistake but has the intimation come from the AO. If it has come from the AO the he will rectify the mistake and cancel the demand if he doesn't do that then appeal against the intimation

AO can honour your intention to rectify and he did, he accepted your return of income and made assessment despite of your wrong pan quoted, but he is not authorized to rectify the TDS, for which the deductor is required to make request to their CIT(TDS) or revise the tds return. 

deductors TDS is not the zone of your ITO

Thanks, for the prompt response,

There is no TDS, the Tax i refered hereinabove is Self Assement Tax paid.

The Intimation was recd from the A.O and in response to the same we have filed Application u/s 154 of the IT Act.
