TaxTim highly recommended out of personal experience.

What a breeze doing a tax return via TaxTim. No stress because the process to complete the return does it for you. All you do is yes/no and the process pulls your information in. The consultants are very responsive and the turnaround time on questions is rapid. If you cannot take the stress and pressure of completing a tax return, or do not trust the outcome of auto-assessments, then I highly recommend TaxTim as your answer. This is my second year that I have used them.
