LDC certificate

Dear Experts,

One of the vendor has availed LDC for FY-2021-22. The maximum amount mentioned in the LDC certificate is utilized and we are deducting tax at higher rate. Now the same vendor has availed LDC for FY-2022-23.

Now we have received bill of last year should we deduct tax as per new LDC or normal rate of TDS as per IT.

Please suggest me how to go about this.

Thanks and Regards
