Expat Tax Compliance and SARS Foreign Income Exemption Assistance
Expat tax compliance in South Africa requires declaring all foreign income to SARS, applying the foreign income exemption correctly, claiming foreign tax credits under Section 6quat properly, and ensuring full supporting documentation. Professional assistance helps ensure compliance, reduces tax liability, and protects against audits and penalties.
What Is Expat Tax Compliance?
Expat tax compliance refers to:
- Correct declaration of foreign income
- Correct use of exchange rates
- Ensuring workings are documented and stored properly
- Building an audit file that defends claims made on a return
- Identifying areas of risk and drafting defences before filing a return
- Applying exemptions and other relief mechanisms such as foreign tax credits
- Adherence to SARS regulations
- Being able to assess whether a DTA or the exemption applies
Key Requirement: In certain instances, a taxpayer may provide services to an employer outside South Africa but not fulfil all the criteria required for the income to qualify for exemption. In these circumstances, the taxpayer is expected to:
- Seek advice from an expert to confirm that the requirements have not been fulfilled, as individuals often inaccurately calculate days within a 12-month period
- Identify the foreign tax credits the taxpayer is eligible to claim in South Africa
- If foreign income results in tax due in South Africa, consult a tax practitioner to determine any obligations regarding the filing and payment of provisional taxes, as late payments are subject to significant penalties
- File a tax return declaring the income to SARS
Why Compliance Is Critical
Failure to comply can result in:
- Understatement penalties of up to 200%
- Interest charges backdated to the due date, which is the end of the tax year
- SARS Section 95 estimated assessments, where SARS deems all income as taxable and gives a taxpayer 40 business days to file a correction
- SARS deducting funds from a taxpayer’s bank account, investment, or garnishing order against employment income
- Criminal prosecution
Core Components of Expat Tax Compliance
1.Tax Residency Determination
When working in a foreign country a taxpayer must:
- Assess if they remain tax resident or if they have ceased tax residency
- If tax residency was ceased, apply to SARS and await a formal letter of confirmation
- Where a taxpayer ceases tax residency, determine any capital gain on the deemed disposal of assets
- Pay provisional taxes where amounts will be due to SARS
2. Foreign Income Declaration
All income must be declared including salary, bonuses, and allowances.
For taxpayers classified as treaty residents under a DTA, it is strongly advised to consistently file an annual tax return disclosing foreign income, reported to SARS as exempt under the provisions of the applicable Double Taxation Agreement.
If a taxpayer intends to reside permanently in another country and has the ability to do so, it is advisable to address any retirement funds following the three-year waiting period before proceeding with the deactivation of their tax number.
For taxpayers planning to return to South Africa in the future, it is advisable to secure an annual tax residency certificate from the foreign country, accurately calculate the exempt income, and report this amount to SARS accordingly. When a taxpayer relocates back to South Africa, they must notify SARS, which will subsequently update their status to a tax resident.
3. Exemption Application
Apply Section 10(1)(o)(ii) correctly during an identified 12-month period:
- Meet the 183 full days outside SA rule
- Meet the 60 consecutive day rule
- Ensure the taxpayer has an employer and employee relationship
- Prove which portion of income is SA sourced and which is foreign sourced, as only foreign sourced income ranks as a deduction under Section 10
- Ensure proper record retention proving all requirements
4. DTA and Tax Credits
Apply where applicable:
- Reduce double taxation by virtue of a DTA
- Claim the Section 10(1)(o)(ii) exemption when not meeting DTA requirements
- Claim foreign tax credits when not meeting DTA requirements
Compliance Process: Step by Step
- Calculate total foreign income
- Confirm tax residency
- Apply DTA if applicable
- Apply exemption where DTA is not applicable
- Claim foreign tax credits if applicable
- Submit SARS return
- Defend audit and dispute any additional assessment if applicable
- Maintain documentation

Real-World Compliance Scenario
A taxpayer commences permanent employment in Mauritius beginning March 2026. The taxpayer’s spouse and children continue to reside in South Africa. The taxpayer travels back to South Africa for two weeks every four months, thereby complying with all requirements under Section 10(1)(o)(ii).
- Taxpayer remains tax resident of South Africa as his real home is where his wife and children are
- Tax year 2027
- Income: R2,200,000
- Taxes paid in Mauritius: R500,000
Item | Amount |
Income | R2,200,000 |
Exemption | -R1,250,000 |
Taxable | R950,000 |
Tax on amount | R268,333 |
6quat | -R215,909 (R950,000 / R2,200,000 x R500,000) |
Tax due to SARS | R52,424 |
Tax due to SARS could be further reduced with planning. For example, the taxpayer could obtain a retirement annuity of up to R261,250 (27.5% of taxable income), potentially reducing the tax liability to zero.
Without Assistance:
- Inability to prove compliance with all exemption rules
- Inability to claim foreign tax credits as this is a complicated claim
- Failure to identify the need for provisional taxes
- Unable to further reduce tax liability with a retirement annuity deduction
- Inability to respond to SARS questions appropriately
- Unable to dispute any SARS additional assessment
With Assistance:
- Exemption awarded in full
- Foreign tax credits awarded in full
- Audit file built for proper defence
- Readiness to dispute any SARS additional assessment
- Understanding of provisional tax requirements
- Full compliance and peace of mind
- Tax practitioner understanding SARS administration rules and escalating cases exceeding turnaround times
Documentation Required for SARS
Mandatory records:
- Passport copies
- Days in and out of the country
- Employment contract or secondment letter
- Payslips for the full tax year
- Income compilation showing how income is calculated and exchange rates used
Best Practice
Seek professional consultation to verify the accuracy of the setup. A specialist would evaluate the contract and provide recommendations, as certain agreements identify the individual as a contractor rather than an employee.
A specialised tax practitioner would also conduct research on the country in which the taxpayer is employed and fulfilling tax obligations. This facilitates effective planning, including liaising with the foreign employer to understand the foreign country’s PAYE regulations, requirements for filing a foreign tax return, and the terms under which a tax charge becomes a final tax charge legitimately levied.
Common Compliance Failures
Issue | Impact |
Not declaring income | SARS Section 95 estimated assessments, severe penalties, large amounts due and payable |
Incorrect application of exemption criteria | Full tax liability, provisional underpayment penalties |
Poor records | SARS additional assessments, costly dispute process |
SARS Audit Risk
High-risk profiles:
- Income above R750,000
- Claiming deductions such as travel
- Involved in a trade such as a rental trade, sole proprietorship, or partnership
- Any claim against the Section 10(1)(o)(ii) exemption
- Any claim against foreign tax credits
Audit Triggers
Trigger | Risk Level |
Income under R1m, no deductions | Low |
Income under R1m, travel claim | Moderate |
Income R1m+ with travel claim | High |
High or low income with rental loss | Very High |
High or low income with Section 10 deductions | Very High |
High or low income with foreign tax credit claims | Exceptionally High |
Income R2m+ | High |
What Happens During a SARS Audit
After a return is submitted, the majority of cases receive an immediate assessment. Assessments include an audit indicator marked as Yes or No. If the audit marker is Yes, a link will automatically generate within approximately 15 to 20 minutes.
Taxpayers are required to upload the necessary documents within 21 working days. However, tax practitioners are expected to complete this process within one working day, as the audit file must be prepared prior to submission of the return, not afterward.
- SARS issues correspondence requesting documents
- A link appears where documents can be uploaded
- Documents should be uploaded neatly and in order, with summaries supported by documents merged together
- Documents should support the return that was filed, and any identified risks should include a short explanation
- SARS verifies the information
- SARS may request more information or documents
- SARS then decides whether to agree with the assessment, issuing a completion letter if agreed, or an additional assessment if not
- If the taxpayer is aggrieved by the assessment, they may lodge a dispute within 80 working days in accordance with published rules
Key Risk: If a taxpayer claims the R1,250,000 foreign tax exemption without clearly specifying the initial or subsequent 12-month period, SARS may request further clarification or issue an additional assessment. Similarly, submitting payslips as evidence of a final tax charge in a foreign country may result in SARS requesting a foreign tax assessment. Taxpayers must exercise caution when providing responses, as their answers could inadvertently compromise their case.
Cost of Non-Compliance
Issue | Cost |
Understatement and underpayment penalties | Up to 200% understatement penalty plus up to 20% provisional underpayment penalty plus backdated interest from due date |
Late filing administrative penalties | R250 to R16,000 per month for each month a return is outstanding |
High debts due to SARS | Large amounts payable that may take many years to resolve |
Cost vs Compliance
Option | Cost | Risk |
DIY | Low | High |
Specialist | Medium | Low |
When You Need Professional Assistance
You should use a specialist if:
- Income exceeds R750,000 and you are claiming deductions such as travel claims
- Income exceeds R2,000,000, even with no deductions
- Claiming any amount against the Section 10(1)(o)(ii) exemption
- Claiming any amount of foreign tax credits
- Running a sole proprietorship, partnership, or claiming against commission income
- Past returns are outstanding
- Prior SARS issues exist
Benefits of Professional Assistance
- Accuracy A tax practitioner is highly trained in tax law and possesses extensive experience in managing cases with SARS. This is especially true when a tax practitioner whose primary expertise lies in taxation is not diverted by additional responsibilities such as bookkeeping, accounting, and payroll. Tax professionals possess the expertise to accurately apply tax regulations to an individual’s specific circumstances and proactively identify potential risk areas prior to submission.
- Risk Reduction A tax practitioner meticulously evaluates claims pertaining to income. When claims seem unusual, further measures are implemented to mitigate the associated risk. For example, if a taxpayer declares R30,000 in repair expenses for a rental property, a tax practitioner would recognise that SARS might interpret these costs as capital in nature and would provide deeper analysis to justify the classification as revenue-based.
Similarly, a tax practitioner would recognise that PAYE in a foreign country functions as a provisional tax rather than a definitive final tax liability, and would examine the tax regulations of the relevant country to determine whether the taxpayer is obligated to file a tax return in that foreign jurisdiction.
- Tax Optimisation A tax practitioner may provide strategic recommendations to minimise a taxpayer’s South African tax obligations. For example, a South African tax resident earning R2,000,000 while working abroad and qualifying for the Section 10(1)(o)(ii) exemption may further reduce their tax obligations by claiming foreign tax credits and contributing to a retirement annuity.
- Peace of Mind With extensive experience in managing similar cases and a comprehensive understanding of SARS processes, the tax team is well-versed in SARS expectations. They have established strategies to address queries and navigate complexities, giving the client confidence that the case is in good hands.
ROI Analysis
A taxpayer accepts an employment contract in Mozambique starting October 2026, earning R100,000 per month on the foreign contract.
The taxpayer had South African sourced income of R1,000,000 from March to September, with the additional foreign income taxable at 41% if not allowed as a deduction.
The taxpayer met all requirements under Section 10(1)(o)(ii) to have R500,000 exempted (R100,000 x 5 months) but failed to demonstrate the exemption to SARS. A specialist tax practitioner had the assessment overturned through a formal dispute.
Item | Amount |
Tax saving | R205,000 |
Specialist fee | R20,000 |
Net benefit | R185,000 |
If the taxpayer had used a specialist to submit the initial return, the cost would have been approximately R15,000.

Frequently Asked Questions
Do I need to declare foreign income?
Yes, always. If a taxpayer qualifies as a tax resident of South Africa and meets the requirements under Section 10(1)(o)(ii), they are eligible to deduct R1,250,000 from their foreign income. Foreign tax credits should also be claimed provided all criteria are satisfied. When a taxpayer qualifies under a DTA and ceases tax residency, all foreign income becomes exempt regardless of whether it exceeds the R1,250,000 threshold, provided the appropriate procedure to update tax residency status with SARS is followed.
What happens if I do not declare?
Under the Tax Administration Act, SARS is authorised to issue an estimated assessment under Section 95 where a taxpayer neglects to submit an income tax return. SARS may acquire information through international information-sharing agreements or by reviewing deposits into an individual’s bank account. If such an assessment is issued, the taxpayer has 40 days to submit a correction.
Failure to meet this deadline may result in the assessment becoming final. SARS may also impose a 20% provisional underpayment penalty and backdate interest to the payment due date of the return rather than the submission date.
Can a specialist reduce my tax?
Yes, legally. A specialist also protects a taxpayer from disallowed deductions and tax credits.
Is assistance worth it?
Yes, definitely. Expats typically specialise in their own professional fields, which often means they lack comprehensive experience with the complexities of legal procedures and SARS processes. Handling such matters without specialist assistance could lead to significantly higher costs in the long term.
What is the difference between an audit and an additional assessment, and what should I do if I receive either?
An audit occurs when SARS requests supporting documents to verify a submitted return. An additional assessment is the formal outcome where SARS disagrees with a claim and imposes a higher tax charge. The two are related but distinct — an audit is a verification process, while an additional assessment is a revised tax liability.
If you receive an audit request, upload a well-organised audit file within the required 21 working days. If SARS then issues an additional assessment, a formal dispute must be lodged within 80 working days in accordance with SARS dispute rules. A suspension of payment request should accompany the dispute to prevent SARS from collecting the assessed amount while the matter is being resolved. Failing to do so means SARS can legally collect the outstanding amount even while the dispute is in progress. Both processes require specialist intervention, as errors in how documents are presented or legal grounds are formulated can significantly reduce the chances of a favourable outcome.
