A company is taxed on the income earned in the preceding financial year. This means that income earned in the financial year 2019 will be taxed in 2020.
In tax terms, using the same example as above, 2020 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.
Examples Based on Different Financial Year Ends
Financial Year End | Basis Period | YA |
---|
31 Mar of each year | 1 Apr 2018 - 31 Mar 2019 | 2020 |
30 Jun of each year | 1 Jul 2018 to 30 Jun 2019 | 2020 |
31 Dec of each year | 1 Jan 2019 - 31 Dec 2019 | 2020 |
The same rule applies to new companies.
