Each period below is statutory. They are set out here so any date the calculator produces can be checked against the provision it came from rather than taken on trust.
Annual return
SSMWithin 30 days of the anniversary of incorporation.
This is the one most often mis-diarised. It runs on the incorporation date, not the financial year end, so a company incorporated in March with a December year end has two unrelated annual clocks. Under the previous Act it followed the AGM; that link is gone.
Companies Act 2016, s.68
Audited accounts circulated to shareholders
SSMWithin 6 months of the financial year end.
The audit has to be finished before this can happen, and the audit cannot start until the accounts are ready. That dependency is why a company which leaves its bookkeeping to year end compresses everything downstream.
Companies Act 2016, s.258
Financial statements lodged with the registrar
SSMWithin 30 days of circulation to shareholders.
Because it runs from circulation rather than from the year end, circulating early moves this date earlier too. The calculator shows it at the latest permissible circulation date, which is the worst case.
Companies Act 2016, s.259
Corporate tax return (Form C)
LHDNWithin 7 months of the close of the accounting period.
LHDN's annual filing programme has generally allowed a further month for e-Filing. Treat that as a concession that has to be confirmed each year, not as the deadline — the statutory date is the one that governs.
Income Tax Act 1967, s.77A
Tax estimate (CP204)
LHDNNo later than 30 days before the start of the basis period.
This one falls due before the year it relates to has begun, which is why it is missed more often than any other item on the list. Instalments are then paid against the estimate during the year, and under-estimating can attract a penalty on the shortfall.
Income Tax Act 1967, s.107C
EPF, SOCSO, EIS and monthly tax deduction
EPF · SOCSO · LHDNBy the 15th of the month following the payroll month.
Separate schemes, separate registrations, one shared deadline. There is no meaningful grace period — late payment attracts a penalty per scheme immediately.
Respective statutory schemes
Form EA to employees, Form E to LHDN
LHDNForm EA by the end of February; Form E by 31 March.
Both fall early in the year, well before the corporate tax deadline most finance teams are watching, which is why they get overlooked by companies that are otherwise current.
Income Tax Act 1967, s.83
SST-02 return
Royal Malaysian CustomsBy the last day of the month following each bi-monthly period.
Periods run on a fixed calendar cycle — January–February, March–April, and so on — regardless of your financial year. A return is due for every period, including periods with nothing to declare.
