Problem	First question	Immediate control
Foreign income disappears	Was it saved, submitted and assessed?	Preserve each version
Exemption disappears	Does the taxpayer substantively qualify?	Maintain an independent computation
Residence status changes	What facts and decision support the change?	Obtain the notice and effective date
UK relocation	Which domestic and treaty tests apply?	Prepare a two-country chronology

A return that appears correct on screen may produce a different saved version or assessment. Where foreign income or an exemption is involved, the discrepancy can be material. The practitioner needs to establish what the taxpayer should declare and what the system actually received.

Practitioners reported disappearing foreign-income fields and changes in recorded residence status at the 23 October 2026 TaxCafe webinar. Each affected return still requires its own diagnosis. Compare the saved, submitted and assessed information against an independent tax computation before attributing the difference to software.

Prepare an independent residence and income computation

Residence under section 1 of the Income Tax Act 58 of 1962 is a legal conclusion drawn from the facts and, where applicable, a double taxation agreement. Residents generally fall within a worldwide-income basis; non-residents require a South African-source analysis. Citizenship, immigration permission, a foreign address and tax residence are distinct matters.

Prepare a schedule identifying each income stream, the person earning it, where the services were performed, the period of accrual, currency conversion and the basis of any exemption or foreign-tax credit. Use that schedule to check the return after any change in the wizard or available fields.

For a client who ceased to be resident, preserve the submitted declaration, supporting documents, South African Revenue Service (SARS) correspondence and effective date. Revisit the substantive position if the facts change. A client may genuinely re-establish South African residence; an unexplained profile change may instead be an administrative mismatch. SARS: cessation and reinstatement of residence.

Client conversation trigger: For every client claiming non-resident treatment, maintain a dated residence memorandum and the SARS correspondence supporting the recorded effective date.

Treat a UK move as a coordinated two country exercise

A move to the United Kingdom does not create a universal “six-month tax holiday”. Domestic residence rules must be considered in both countries. If both regard the individual as resident, the applicable treaty tie-breaker requires its own factual analysis. The employment-income article then addresses taxing rights over remuneration; it is not the residence test.

The UK–South Africa treaty must be read with the 2010 Protocol and applicable modifications under the Multilateral Instrument. The published synthesised text assists with that reading. Practitioners should use the version relevant to the period concerned rather than an unamended treaty downloaded years earlier. HMRC: synthesised UK–South Africa treaty.

Prepare a calendar of workdays, travel, homes available, family movements and employment changes. The countries’ tax years do not align, so a foreign assessment may not map directly to a South African return. Foreign tax paid should be traced to the same income and relevant period before calculating relief. Departure may also require an exit-charge analysis under section 9H of the Income Tax Act; changing the residence field is not the whole compliance exercise.

Client conversation trigger: For UK-bound or returning clients, coordinate both tax-year calendars and obtain foreign payroll and assessment records before calculating South African relief.

Prove the system discrepancy and protect the remedy

Capture the return before saving, reopen it, inspect the calculation and retain the submitted version and assessment. Record the tax year, field, amount, time and exact error. A useful query says that a specified R-value in a specified field disappeared between two identifiable stages. “Foreign income is broken” is much harder to investigate.

Protecting the tax position when foreign income fields change - decision path

Do not move income into an inappropriate code merely to make an exemption appear. If an assessment is wrong, determine whether a request for correction, another statutory correction mechanism, or objection is appropriate. The Tax Administration Act 28 of 2011 governs those remedies. A technical support ticket does not automatically preserve an objection period or suspend payment.

Where a residence change lacks an explanation, request the relevant decision and reasons rather than assuming its cause. The file should show both the steps taken to correct the profile and the measures taken to protect the taxpayer against the resulting assessment.

Client conversation trigger: Where a system discrepancy affects tax payable, agree who will handle the technical escalation and separately diarise the available tax remedy.

Practitioner action checklist

#	Area	Issue	Clients affected	Action required	Timing
1	Computation	Foreign income and relief	Cross-border earners	Build independent schedule	Before capture
2	Residence	Status and effective date	Migrating clients	Preserve factual and SARS record	On change
3	System	Saved/submitted mismatch	Affected returns	Retain versions and error details	Immediately
4	Remedy	Assessment consequences	Adversely assessed clients	Diarise correction and dispute route	On assessment

Retain the independent tax computation alongside the saved return, submission receipt and assessment. This gives the practitioner the evidence needed to correct a discrepancy and pursue any resulting dispute.

Frequently asked questions

Why did my foreign income disappear from my eFiling return?

Practitioners reported disappearing foreign-income fields and residence status changes at the 23 October 2026 TaxCafe webinar. Compare the saved, submitted and assessed information against an independent computation before attributing the difference to software.

Does citizenship decide tax residence?

No. Residence is a legal conclusion drawn from the facts and, where applicable, a double taxation agreement. Citizenship, immigration permission, a foreign address and tax residence are distinct matters.

What should I keep if SARS assesses a different amount?

Retain the independent computation alongside the saved return, submission receipt and assessment. That evidence supports a correction and any resulting dispute.
