In April 2013 the Government Gazette published a Notice that SARS requires you to submit IT3 forms in respect of Interest earned on Investments.
The IT3(b) form is issued by the bank or financial Institution that your Attorney firm has Invested the money with. The Financial Institution will send the IT3(b) to the attorney firm only if the Investment account has received credit Interest and if the interest amount is above the SARS threshold.
The IT3 (b) certificate is produced annually by the Financial institution and it states how much interest was earned during the Tax year (March to February) and it is sent at the end of February each year.
Once the attorney firm has received the IT3(b) form then the return needs to be electronically submitted on SARS eFiling.
