Pakistan Traders Association is observing a strike today (Wednesday) in protest against the withholding tax.
The traders termed the imposition of 0.3 percent withholding tax on all bank transactions unjustified and called for a shutter-down on Wednesday.
Pakistan Tehreek-i-Insaf, Jamaat e Islami and Muttahida Qaumi Movement have also announced to support the strike.
They were of the view that the levy was undue and that it will burden the trade fraternity.
