TDS (Tax Deducted at Source) how to deduct on bill

Hello,
On purchase, on generating bill, how to deduct the TDS (Tax Deducted at Source), which is 1.5 in Nepal, I don't about other country. So when purchase goods, there 13% vat added to amt and 1.5 % amount minus. If I put -1.5% TDS, the trial balance report is wrong. If I don't add TDS, the trial balance report is correct. It is minus on amount so, I can't add 1.5 to bills. So, how can we deal with this?
I hope someone has a solution to this. Or is this issue with double entry system?
Regards,

Hello,

You can use the Withholding tax type for that purpose.

I changed to type to withholding and it's working fine.
