Estimated Chargeable Filing (ECI) is a compulsory filing requirement for companies unless the company qualifies for a waiver. There are advantages for companies that file their ECI earlier and within the qualifying period as they may opt to pay corporate taxes by instalments.
The benefits for filing ECI early are:
1) Instant acknowledgement upon successful e-filing of your ECI; and
2) A greater number of instalments to pay your company’s estimated corporate taxes.
To encourage earlier filing of ECI, ACRA will give companies more months of instalments the earlier they file. Thus the earlier the ECI is filed, the greater the number of instalments will be given for payment of corporate taxes. This will greatly help the company in its cash flow.
