Any idea how to sort things out if the company made a mistake by paying more than what they should? I haven't opened my payslip for few months and just realised the mistake they made.

As income tax filing date is close I would like to know how to sort out the numbers. I don't mind paying them back the extra or have deduction in my upcoming payslip but the tax/EPF contribution seems abit complex.

At the end of the day I don't wanna pay extra in Tax & EPF due to the finance departments' error.
