The TCS PIN referenced in this post has been replaced by the Approval for International Transfer (AIT). The process is now managed through SARS eFiling.

AIT approval guide
In brief (TL;DR): SARS eFiling is the online portal where SA taxpayers submit returns and manage their tax affairs. For expats in the UK, it is the main way to stay compliant — but common issues like lost passwords and old SA mobile numbers make access frustrating. WBForex can manage your eFiling profile on your behalf.

SARS eFiling is the online portal where South African taxpayers submit returns, make payments, and manage their tax affairs. For SA expats in the UK, it is the main way to stay on top of your SARS obligations without having to fly home.

Registering for SARS eFiling

You can register at www.sarsefiling.co.za. You will need your SA ID number, tax reference number, a valid email address, and a South African mobile number for the one-time PIN verification. If you no longer have a SA SIM card, this last requirement becomes a problem — WBForex can help you register or regain access directly through SARS.

The SA tax year runs from 1 March to 28 February, with filing season typically opening in July. Log in, navigate to Returns, select Income Tax, pick the relevant year, complete the ITR12 form, and submit. It sounds straightforward, but expat returns often have added complications — foreign income declarations, the expat exemption under Section 10(1)(o)(ii), and deemed disposal calculations for those completing cessation.

Applying for an AIT through eFiling

An Approval for International Transfer (AIT) is required for any transfer above the SDA limit. The application is submitted through SARS eFiling. SARS typically processes it within two to four weeks, though this depends on the completeness of your application and your compliance status. WBForex prepares and submits the full application on your behalf.

Moving money soon? See how your rate compares to your SA bank — most clients are surprised by the difference.

Your SARS registration details — address, contact numbers, banking details, and residency status — are maintained through the RAV01 form on eFiling. Keeping these current is important, especially if you have moved to the UK. Outdated details cause complications with AIT applications and cessation filings.

Common problems SA expats run into

No SA mobile number: SARS requires an SA mobile for OTP verification. Contact SARS to update your details, or let WBForex handle the access recovery.

Outstanding tax returns: SARS will not process an AIT or cessation application until all previous returns are filed. If you have gaps, sort them out first.

Forgotten password: Use the reset function on eFiling, or call SARS support directly. If you are stuck, WBForex can manage the process using a signed power of attorney.
