withholding tax

Hi Expert,

if i set accumulation per year with starting month 04 in tax type creation & maintain the minimum base as 50000 than it is deducting the tds if more than 50000 rs posting is made in a year.

in same case we want to deduct the tds if a single invoice amount exceeds 20000 rs.

Please let me know how to configure. Send Details Information.

thanks in advance
