How Reconciliation Works

SARS receives tax certificate data directly from employers, banks, and medical aids. They compare this to what you declare on your tax return.

Common Mismatches

Common mismatches include incorrect source codes, missing income sources, different amounts between your certificate and return, and discrepancies in medical aid contributions.

How to Fix Errors

If SARS identifies a mismatch, they may request verification documents. Correct any errors on your return by submitting a Request for Correction.
