If you're a PR or SC (I don't think this is open for EP or Spass holders - it MAY work for PEP) and you can change the way you work to being a contractor (billing multiple companies with invoices and not being on their payroll - i.e. an SEP) you can deduct your full SRS and CPF contributions as tax deductions (rather than the usual 7k or so allowance).
My tax deductions for YA2022 were:
Earned Income 6,000.00
Child (QCR) 4,000.00
CPF 37,740
SRS 15,300.00
For a total of ~$63,000. I paid all of $424 in income tax for YA2022.
In addition as a contractor or trader or sole proprietor you can off course deduct legitimate business expenses from your income prior to declaring it (and if under 500k you don't need to file accounts). Mobile phones, computers etc are depreciated within 12 months I believe as well.
If you're laid off from a regular job (as I was) this is an interesting option as a PR or SC. I now contract to multiple Singapore companies for regular and irregular work as well as offshore companies.
