Despite repeated requests from traders, the Federal Board of Revenue (FBR) refused to extend the date for filing tax returns.
A spokesman for the FBR said all commercial banks would be open to taxpayers until 9pm on 8th December.
All FBR field offices will also be open to taxpayers until 10 p.m.
The spokesman said taxpayers can also file online income tax returns by 12 midnight.
8th December was the last date for submission of tax returns and only 1.3 million returns have been submitted.
