Key requirements
Use accounting software with the relevant ASR+ corporate tax features and maintain operating transactions within it. A one-time mapping links the chart of accounts to prescribed tax data elements; incorrect mapping can undermine the resulting draft. The authorised Corppass Approver reviews the draft C-S, profit and loss statement, tax computation and schedules before making the declaration. Only the C-S is routinely submitted through this workflow; supporting documents remain stored for IRAS requests. The process still depends on the company meeting C-S eligibility conditions and observing the ordinary filing deadline. Automation assists preparation but does not transfer responsibility for the accuracy of the tax treatment.
