IT3(b) Interest Certificates — What SARS Already Knows

If the bank sent it to SARS, the gap on your return is a gift to verification.27 September 2026 All articles

What it is

An IT3(b) reports investment income — typically local interest — for a tax year. Download it from the bank or accept the eFiling pre-populate after you check the rand amount.

Multiple accounts

Every South African interest-bearing account can produce a certificate. Add them. The exemption applies to the total, not per bank.

IT3(c) is different

IT3(c) is the capital-gains / dividend-type certificate from a broker. Do not paste an EasyEquities disposal into the interest line.

Questions

What if eFiling shows interest I do not recognise?
Call the bank and match the account number. Do not delete a third-party line because it is inconvenient.

It is not professional tax advice. Deductibility depends on your facts. Confirm current figures on sars.gov.za before you file.
