Employer deducting more PAYE than they should

My current employer is deducting more tax than what they should on my salary. I have complained and they say that their system is programmed to do that. I have used several tax calculators even the SARS one but it still proves that I'm paying about R700 more for tax. Please advise if SARS will refund me back this money (all the R700 paid for each month?)

Yes they will refund the amount when you submit your tax return. Register for TaxTim and let us ask you all the right questions to make sure you get your maximum possible refund.
