I started working in April this year, when do I have to start paying tax?

Tax season runs from 01 March to the last day of February the following year so you would only need to submit your tax returns in 2013. Your employer will deduct tax each month and pay it over for you. This is called Pay-As-You-Earn (PAYE). It means that at year end you won't have to pay over a large amount as it is done for you already.

You need to register as a taxpayer, follow the easy guidelines on https://www.taxtim.com/za/get-a-tax-number.php Tim guides you through the whole process!

Thanks a lot for your response!
