Good to know

Legal basis: Income Tax Act, 2023, its amendments and NBR guidance for the current income year. Under NBR guidance, online returns (e-Return) are generally mandatory for individual taxpayers, with certain specified exceptions.

  • Under NBR e-Return guidance, supporting documents usually do not need to be uploaded when filing online. They should still be collected and kept, for accurate computation and any later verification.
  • After filing online, an acknowledgement slip and tax certificate are available.
  • We do not guarantee any assessment outcome or a specific amount of tax saving; we work to ensure accurate computation and timely filing.

What you receive: tax computation, copy of the filed return, acknowledgement slip and tax certificate.
