Demand to extend ST deadline Business May 6, 2021 KARACHI: The Pakistan Tax Bar Association (PTBA) has urged the tax authorities to extend the date for filing monthly sales tax returns, as meeting the deadline is not possible for taxpayers due to weeklong Eid holidays and restrictions imposed to prevent the spread of coronavirus. The PTBA on Wednesday sent a letter to Federal Board of Revenue (FBR) Chairman Asim Ahmed, informing him that tax bars in the country had shared difficulties in returns filing due to the prevailing situation. The PTBA said: “The government has announced national holidays from May 8 to 15, 2021 due to Eid-ul-Fitr and the current situation of the third wave of pandemic in the country.”
