ydnerendy,
Please go back and read the links I provided to you in the beginning.
Additionally, when the tax clearance is finalized by Inland Revenue, you won't have to worry about your Employer screwing you as Inland Revenue sends both the employee and employer a tax statement declaring how much your tax liability is. Therefore, if your employer tries to deduct more then you have reason to revert to IRAS to have them sort it out.
There is NO EP TAX,
There is NO STUDENT/TRAINING TAX,
There is ONLY INCOME TAX and the IRAS will send you a statement as to how much is required to be paid by your employer. The balance of your final salary should then be remitted to you.
If your income was 27K/p.a. then your taxes would be around S$186 for 2008, and if it was the same for 2007 then around S$245 or less than $500 for the two years. Don't sweat it.
