Basis Period and Year of Assessment

In tax terms, using the same example as above, 2019 is the Year of Assessment (YA). In other words, the YA is the year in which your income is assessed to tax.
To assess the amount of tax, IRAS looks at the income, expenses, etc. during the financial year. This financial year is known as the “basis period”.
The basis period is generally a 12-month period preceding the YA.

Attribution of Profits / Losses for New Companies

For details on how to attribute the profits/ losses of new companies where the first set of accounts cover more than 12 months. please refer to below Basic Guide for New Companies.

Filing of Estimated Chargeable Income (ECI)

New companies incorporated in 2017 are required to file the ECI within three months from the company’s first financial year end.
If your company is incorporated in 2017 and closes its first set of accounts in 2017, no ECI filing notification will be sent to you in 2017 as most companies do not close their first set of accounts in the year of incorporation. However, you are still required to file the ECI within three months from your company’s first financial year end, unless the company qualifies for the administrative concession and does not need to file the ECI.
As most companies have their financial year end on 31 Dec, a new company is required to inform IRAS if its financial year end is not 31 Dec.
Otherwise, you will receive the ECI notification from IRAS in Dec, starting from the year after the year of incorporation. If your company is incorporated in 2017 and closes its first set of accounts in Dec 2018, you will receive a ECI notification from IRAS in Dec 2018 reminding you to e-File your ECI by Mar 2019.

(Refer to below Notes)

Notification sent in 2018


As the company’s first set of accounts covers a period of more than 12 months from the date of incorporation, its profit/losses must be attributed and declared under two Years of Assessment (YAs) as follows:

  • YA 2018 covering the basis period from 15 Jul 2017 to 31 Dec 2017; and
  • YA 2019 covering the basis period from 1 Jan 2018 to 31 Dec 2018.

Time apportionment basis may be used if the company is not able to directly identify income and expenses to the two periods.

Companies That Do Not Need to Submit ECI

To reduce the compliance cost on businesses, IRAS has increased the annual revenue threshold for ECI waiver from $1 million to $5 million. Your company does not need to file its ECI for the particular YA if it meets the following criteria:

Company’s Financial Year End (FYE)Criteria for ECI waiver
In or before Jun 2017
  1. Annual revenue is not more than $1 million for the financial year; and
  2. ECI* is NIL for the YA.
In or after Jun 2017
  1. Annual revenue is not more than $5 million for the financial year; and
  2. ECI* is NIL for the YA.
Notes: * The ECI should be the amount before deducting the exempt amount under the partial tax exemption or the tax exemption scheme for new start-up companies.
There is no need to inform IRAS if the company meets the conditions and does not need to file its ECI.

Expenses Incurred before Commencement of Business (or) Revenue

Generally, expenses incurred before a business starts its operations are not tax-deductible as these are incurred for the purpose of setting up the operations and not ‘wholly and exclusively’ for the production of income.
IRAS allows deductible for tax purposes for business in enterprise development, revenue expenses incurred one year prior to the deemed date of commencement of business.
