There are probably calculators online for this, but here is how to calculate it manually.
Take you annual salary and apply the formula as per the first table in that document.
Thus, if it is less than R160k: Annual Income * 0.18
If if is between R160k and R250k: ((Annual Income - R160k) * 0.25) + R28800
etc.
Then take the amount above and subtract the rebate (R11440)
This will now be your Total Tax.
Then, subtract your medical expenses (incl medical aid contributions) with the following formula:
Actual Tax Payable = Total Tax - (Total Medical Expenses - (Annual Income * 0.075))
Then simply look at your IRP5 and see your Tax Credits, deduct the Actual Tax Payable from that and you have the amount that you would get back.
