Filing of Estimated Chargeable Income (ECI)

Every company has to file an estimate of its chargeable income to the Comptroller of Income Tax (CIT) within 3 months after the end of its financial year-end unless its revenue is less than $1 million and ECI is nil.

We could assist you with ECI computation and application for instalment of the estimated tax payable. Please forward the following to us so that we could file the ECI in a timely manner.

  • management accounts for the financial period
  • latest tax computation and Form C submitted to IRAS (not applicable for newly set up company)
  • latest Notice of Assessment from IRAS (not applicable for newly set up company)


Please also authorise us in the e-Services Authorisation System so that we could obtain maximum instalments for the company. Our company registration number is UEN Local-co 201203868Z.
