As per clause 1(ba) of Sec 194 J, any remuneration or fees or commission by whatever name called, other than those on which tax is dedcutiable u/s192, paid to a director shall be liable to deduct tax @ 10%. If you refer Sec 198 & 309 of the companies act, director remuneration also includes commission, sitting fees paid to directotors. Hence we have to check the nature of payment made to directors, if tax is not deductiable u/s 192 , it shall covered under 194 J 1(ba).
1. service tax is also applicable on sitting fee paid to directors & this is covered under reverse charge mechanism so Co. need to pay service tax to the dept directly.
