An IT3a is the same as an IRP5, except that it shows employee earnings from which tax has NOT been deducted.
An IT3c is a Tax Certificate received from an institution such as a bank or financial services institution. It is a summary of any disposals you may have made related to the holding of investments with any of these places.
An IT3(s) is a Tax Certificate received from an institution such as a bank or financial services institution. It is a summary of all the details of your Tax Free Savings account for the year (eg. interest, dividends, etc) that you will require when you complete your Tax Return.
An IT3(f) is a Tax Certificate received from a financial services institution. It is a summary of the details of your contribution to a Retirement Annuity Fund made for the year. Note, this is not the same as a Pension or Provident Fund. It is specifically for a Retirement Annuity Fund only.
An IT14SD is required for companies only. It is a schedule which reconciles the business's VAT, PAYE, Income Tax and Customs declarations from the ITR14 to the information submitted to SARS during the year. SARS may request the IT14SD after submission of the ITR14. If it is required, SARS will make it available to the taxpayer via a link in SARS eFiling.
An ITA34 is a summary of your assessment for the tax year. After submitting your tax return, SARS sends you a summary of your submission - this document is called an ITA34. You need to have a look at it and see if you agree, if not then you can dispute the assessment with SARS. If it does not say that you are audited, and you are happy with the result, then you do not need to take any further action after receiving it.
An ITR14 or Income Tax Return is a form that SARS requires all companies registered with CIPC to complete and submit to SARS once every year. The form is used to declare your incomes and expenses/deductions so that SARS can calculate how much tax your business need to pay, or how much of a tax refund SARS needs to pay to you.
If you run a business that is not registered with CIPC, you would enter in your business-related incomes and expenses into your personal ITR12 tax return, under the Local Business section.
