New Companies Filing First Tax Return
If your company's first set of financial statements covers a period of more than 12 months from its date of incorporation, please indicate the relevant financial period under General Info.
In the subsequent pages, you will need to:
- Attribute the company's adjusted profit/ losses to two Years of Assessment (YAs)* (i.e. YA 2016 and YA 2017); and
- Complete the fields required for two YAs in the Form C. This is because the basis period for each YA should generally not exceed 12 months.
For more information on YA and basis period for new companies, please refer to Attribution of Profits/ Losses for New Companies.
