ACRA's dataset does not describe these two fields. No annual return date in it is ever in the future, so it is shown here as the date of the latest annual return, and the account due date as the date the next financial statements are due. ACRA sets the annual return deadline from the financial year end: 7 months for a non-listed company and 5 months for a listed one (8 and 6 months with a share capital and an overseas branch register). Seeannual return and financial statement deadlines.
