"Preceding Year [PY] Basis of Assessment
3. Our current income tax system has the following characteristics:
„h Basis Period of Assessment: The incomes derived by individuals and companies are assessed for tax on a preceding year basis. In other words, income tax payable this year is based on income earned in the previous year.
„h Method of Assessment: Singapore currently operates an Official Assessment System (OAS). This means that the legal onus is on IRAS to assess the tax liability based on the taxpayer¡¦s declaration of income. IRAS will then issue a Notice of Assessment on the amount of tax payable.
4. In addition, companies are required to file an Estimated Chargeable Income (ECI) within 3 months from the end of the accounting year. Hence, a company whose accounting year ends on 31 Dec is required to file an ECI by 31 Mar of the following year. The tax computed based on the ECI can be paid in installments.
5. Companies need only submit their final income tax return (Form C) together with their accounts and tax computation by 31 Jul of each year. The final tax liability will be determined based on the return filed.
6. Individuals are required to report their incomes earned in the previous year by filing the income tax return (Form B or Form B1) by 15 Apr of the following year. IRAS then assesses the tax payable and issues a Notice of Assessment to taxpayers. Tax is payable within 1 month from the date of the Notice of Assessment.
7. Taxpayers who are paying income tax via GIRO start paying their income tax based on estimated taxes before their actual tax liability is assessed by IRAS. However, upon the filing of income tax returns and after IRAS has assessed the actual tax payable and issued the Notice of Assessment, the outstanding installments will be adjusted to reflect the actual tax payable.
Current Year [CY] Basis of Assessment
8. Under the CY basis of assessment, the income earned by individuals and companies is assessed to tax on a current year basis i.e. tax is paid based on the income for that year, rather than income of the preceding year. For salaried individuals, the tax amount may be withheld by the employers on a monthly basis from their salaries and then paid to the tax authority. For companies, tax may be paid in installments."

For this current year, we pay last years' taxes. With the new system, they are considering having a Current Year basis of assessment ie What you earn is taxed immediately.
