Why the July 2004 circular changed the basis
The nine-page 21 July 2004 circular addresses non-December year-ends. Previously trade income could use the accounting year while non-trade income and donations used the calendar year, requiring two sets of periods. The circular introduces an elective YA2005–2008 concession and anticipates legislation from YA2009. Its transition dates are historical.
Entities and Singapore franked dividends
The reform covers companies, bodies of persons, sole proprietorships and partnerships whether trading or not. Non-trade income and approved donations in the entity/business name can follow the accounting year. Franked Singapore dividends before 1 January 2008 remain calendar-year items because imputation credits followed that basis. From that date one-tier dividends are exempt. The footnote’s April 2007–March 2008 example taxes April–December 2007 franked dividends in YA2008 and exempts January–March 2008 one-tier dividends.
Partnership and personal income remain distinct
Partnership business and non-trade profits can be computed by accounting year and allocated to individually assessed partners; partnership-name donations follow that year. Partners’ personal employment and asset income remain calendar-year items. For a sole proprietor, only non-trade income incidental to business assets qualifies for accounting-year treatment; other personally held assets remain calendar-year. Business-asset donations are similarly distinguished from personal donations.
The old ECI requirements
The circular’s pre-reform table requires trade estimates within three months for non-December trading companies/bodies and non-December partner/sole-proprietor businesses. December trading entities include trade and non-trade income. December partner/sole-proprietor businesses had an administrative waiver linked to the then 15 April individual return. Entities deriving only non-trade income had no old ECI requirement.
ECI conditions for the new election
Electing trading companies/bodies include non-trade income except net franked dividends in the three-month estimate. Non-December partners/proprietors include business-derived non-trade income; December businesses retain that edition’s waiver. Non-December entities deriving only non-trade income must estimate it within three months. For December non-trade-only entities the reform is irrelevant because books and calendar already align.
Election and irreversibility
For YA2005–2008, making the accounting-year computation elects treatment from that year. An entity may stay on calendar-year treatment before electing but cannot revert afterwards. The document anticipates statutory treatment from YA2009, with the franked-dividend exception and individual personal-income distinction retained.
The first-year calculation and March example
Only include 1 January through accounting-year end in the first switch year because earlier months were already assessed under the prior calendar year. Apply the same principle to approved donations. Company A ends 31 March and elects for YA2006: April–December 2004 was already in YA2005, so report January–March 2005 non-trade income in YA2006 ECI, Form C and computation; ECI is due 30 June 2005.
The special YA2005 ECI window
Because January–April year-ends had already filed estimates when the circular appeared, trade ECI remained due within three months, but an electing entity could add qualifying non-trade income through revised ECI by 31 March 2005. Non-December non-trade-only entities likewise had until 31 March 2005. YA2006–2008 elections require the ordinary three-month estimate. These one-off dates must not be reused for current returns.
