Foreign Income Exemption Mistakes to Avoid (Common Errors and Fixes)
The most common foreign income exemption mistakes in South Africa include miscounting the 183-day requirement, failing the 60-day continuous rule, not declaring foreign income, and poor documentation. These errors can result in full taxation, penalties, and SARS disputes, even if the taxpayer would otherwise qualify for the exemption.
Why Mistakes Are Costly
Foreign income exemption is a request for a large amount to be exempted, with criteria strictly applied by SARS. Taxpayer misunderstandings such as how to identify a 12-month period and how to communicate correctly with SARS are common.
Key Insight: Even small errors can result in complete loss of the exemption.
The 7 Most Common Mistakes
- Miscounting days
- Failing the 60 consecutive day rule
- Not declaring income
- Poor documentation
- Misunderstanding residency
- Incorrect exemption application
- Ignoring DTA
Master Mistakes Table
Mistake | Impact | Risk Level | Fix |
Miscounting days | Exemption disallowed | Very High | Identify first and second 12-month period |
Breaking 60-day rule | Full tax | Very High | Identify first and second 12-month period |
Not declaring income | Penalties, SARS Section 95 estimated assessments | Extreme | Declare fully, claim exemption |
Poor documentation | SARS additional assessment | Very High | Maintain records, tax practitioner to archive safely |
Mistake 1: Miscounting the 183 Days
Problem
Many taxpayers fail to clearly define the starting point for counting days or include days that should not be counted. The primary condition is that the taxpayer must hold employment with an employer. If a taxpayer completes their employment after 170 days but travels to another country to fulfil the additional 13 days required, including those 13 days would be incorrect.
Similarly, some taxpayers consider the day they leave South Africa or the day they return as a full day. SARS considers a full day to span from midnight to the next midnight. The day a taxpayer leaves South Africa does not count as a complete day spent outside the country.
A taxpayer’s 12-month period could begin on 10 January 2026 and conclude on 9 January 2027. Consequently, any days after 9 January 2027 cannot be counted within the initial 12-month period.
A taxpayer should:
- Clearly identify the first 12-month period
- Clearly identify the subsequent 12-month period. Typically, the first day of the following year marks the beginning of a new 12-month period, starting one year after the initial date. However, the taxpayer may choose to forgo coverage for a new 12-month period from 10 January 2027 to 28 February 2027 and instead begin a new 12-month period starting 1 March 2027 to 28 February 2028
- Counting the days within each 12-month period is highly important. Incorrectly counting days within a 12-month period results in SARS disallowing the exemption
Impact
- Fail the day requirement
- Lose the exemption
Fix
- Work with a tax practitioner to clearly identify each 12-month period
- Maintain a record of days in and out of South Africa within both identified 12-month periods
- Cross-check with passport stamps
Mistake 2: Failing the 60 Consecutive Days Rule
Problem
If a taxpayer incorrectly identifies the 12-month period, they might believe they have fulfilled the 60 consecutive days requirement when they have not. In practice, a taxpayer can fulfil the 60 consecutive day requirement twice within the initial 12-month period but fail to meet the same requirement during the second designated period.
For instance, a taxpayer’s 12-month period begins on 1 October 2026 and concludes on 30 September 2027. The taxpayer fulfils the 60 consecutive days requirement from 1 October to 15 December (75 days, excluding 15 December as a full day outside South Africa). The next 60-day trip takes place from 1 July 2027 to 31 August 2027 (61 days). However, the taxpayer overlooks that the new 12-month period begins on 1 October 2027. The taxpayer believed he fulfilled the exemption criteria for both 12-month periods but did not.
Short trips back to SA:
- Break continuity
- Reset the count
Impact
- Entire exemption denied
Fix
- Plan travel with a tax practitioner familiar with foreign tax exemptions
- Avoid unnecessary SA visits
- Plan subsequent 12-month periods carefully
Mistake 3: Not Declaring Foreign Income
Problem
Some taxpayers believe that foreign income falling under the exemption means they are not required to file a return with SARS or declare the income. Their reasoning is: “If it is exempt, I will not declare it.” This approach is incorrect.
A taxpayer is required to request the exemption, which must then be granted by SARS. The proper administrative procedures must be adhered to.
Under Section 99(2)(a) of the Tax Administration Act, SARS may reopen a tax return for a period exceeding five years if it can demonstrate fraud, misrepresentation, or non-disclosure of material facts. The emergence of AI has enabled SARS to identify undeclared income and send notices to numerous taxpayers instructing them to submit or amend their returns.
Impact
- Urgency to acquire historical documents within tight deadlines
- Inability to prove deductions claimed due to lost documents
- Provisional tax underpayment penalties for late payments
- Backdated interest
- SARS raises a Section 95 assessment under the Tax Administration Act
Fix
Always:
- Ensure an annual return is filed
- Ensure proper archiving of documents
- Ensure any abnormalities are documented
Mistake 4: Poor Documentation
Problem
A taxpayer does not submit their 2020 income tax return despite being employed in Ethiopia, earning foreign employment income of R1,000,000, and fulfilling all conditions under Section 10(1)(o)(ii). In April 2026, SARS sends the taxpayer a letter requesting submission of the 2020 return. Suppose the taxpayer lacks the following:
Missing:
- Passport
- Employment contracts
Impact
- Taxpayer is unable to prove that the income is exempt
- SARS taxes the full amount
- SARS charges underpayment of provisional tax penalties
- SARS backdates interest to 1 March 2020 to the date of payment
Fix
Maintain:
- Days in and out of the country within each 12-month period
- The actual passport or a photocopy of all pages
- Payslips
- Workings and exchange rates
- Employment contracts and renewals where the contract is for a fixed term
Mistake 5: Misunderstanding Tax Residency
Problem
A taxpayer leaves his family in South Africa and starts foreign employment in Botswana, where his employer provides accommodation. Whenever possible, the taxpayer returns home to spend time with his family in South Africa.
The taxpayer feels that because a DTA exists between Botswana and South Africa, its mere existence and the fact that he is “working overseas means I am not a tax resident.”
Impact
- Taxpayer incorrectly assumed he is a non-resident
- Taxpayer subsequently did not plan his days out of the country and fails the 60 consecutive day requirement
- Incorrect filing
- If gross income exceeds R1,250,000 and foreign tax credits in Botswana are insufficient to cover the amount owed in South Africa, the taxpayer faces a provisional tax underpayment penalty
- SARS may also levy an understatement penalty under Section 223 of the Tax Administration Act
Fix
Confirm:
- Whether the taxpayer meets the criteria to be considered an exclusive tax resident of the foreign country
- If the criteria are met, submit an application to SARS requesting cessation of tax residency
- Await SARS official acceptance
- Determine any capital gains resulting from the exit tax
- Determine which assets are exempt from exit tax
- Pay provisional taxes where required
Mistake 6: Incorrect Exemption Calculation
Problem
A taxpayer performs remote work for an overseas employer while residing in South Africa and incorrectly applies foreign-sourced income rules by assuming that money received from a foreign employer qualifies as tax-exempt income.
- Applying the exemption incorrectly
- Misunderstanding what qualifies as foreign sourced income
Impact
- Full amount is taxable
- Taxpayer did not pay provisional taxes and is penalised for underpayment
- Interest backdated to the end of the tax year rather than the filing date
Fix
- Identify income correctly
- Identify taxing rights correctly
- Deduct expenses permitted as incurred in the production of income
- File and pay provisional taxes
- Complete the tax return and defend the position taken
Mistake 7: Ignoring Double Taxation Agreements
Problem
On 1 March 2026, a taxpayer and their family vacate their primary residence in South Africa, rent out their South African home, and move to Algeria, where they sign a 12-month lease. The taxpayer earned R3,000,000 during the 2027 tax year and filed their South African tax return claiming a R1,250,000 exemption along with R500,000 in foreign taxes under Section 6quat, without considering whether the DTA applied.
Not using the DTA:
- Taxpayer has a pay-in of R95,973
- Leads to double taxation
- If SARS rejects the foreign tax credits, an additional R500,000 becomes due
- SARS charges an additional 20% penalty for underpayment of provisional taxes
- SARS backdates interest to 1 March 2026
Impact
- Paying unnecessary tax
- Dealing with complicated rules to have the assessment corrected
- Having to urgently apply for a tax residency update with SARS
Fix
- Identify when a DTA is of relevance
- Apply the DTA where applicable
- If the DTA applies, the foreign exemption has no cap. Even if the income is R3,000,000, the full amount is exempt
How to Avoid All Mistakes: A System Approach
- Identify whether DTA or exemption should be used
- If DTA applies, submit an application to SARS and await acceptance
- After official notification, file foreign income as exempt
If the exemption is to be used:
- Identify the first and subsequent 12-month periods
- Document days in and out of the country within each 12-month period
- Document income using SARS approved exchange rates
- Build an audit file
- Submit the return to SARS
- Defend the position taken
- Dispute any additional assessment by SARS in terms of the rules
- Complete the case
- Remember to pay provisional taxes where income exceeds R1,250,000

Frequently Asked Questions
What is the biggest mistake?
Taxpayers are often unable to recognise risk areas. Many believe that handling taxes simply involves filling out a form. Successfully managing a tax case involves thorough preparation, recognising potential areas of risk, addressing them effectively, and being equipped to respond to any SARS enquiries. A good tax practitioner must possess knowledge of tax law, the principles of the accrual system, the criteria for claiming deductions and credits, and must be able to oversee the case from start to finish.
Do I still declare exempt income?
Yes. The return includes a section labelled “amounts considered non-taxable” where SARS must be given the opportunity to approve an amount as exempt.
Can mistakes be fixed?
Yes, but costs increase the more the matter escalates. If a taxpayer loses an audit, an objection becomes more costly. If the objection is also disallowed, the only remaining step is SARS legal, which is substantially more costly. Best practice is to obtain assistance sooner rather than later, as this saves cost, frustration, and anxiety.
Is DIY risky?
Yes, except for straightforward cases where there are no deductions, income is below R750,000, and the taxpayer regularly files on time. For all other situations, consulting a tax professional is advisable. In the long term, this is likely to result in savings, as nearly everyone in a more complex situation is expected to encounter a complication with SARS at some point.
What should I do if I discover a mistake in a previously filed foreign income exemption return and the three-year correction window has already passed?
If the three-year window for refiling has passed and SARS has not yet opened an audit, the options available are more limited but not exhausted.
The Voluntary Disclosure Programme (VDP) is the most appropriate route in cases where income was not declared or was incorrectly declared, as it allows a taxpayer to approach SARS proactively before an audit or investigation is opened.
A successful VDP application may result in a full or significant waiver of penalties, and from 1 March 2026, SARS will also waive backdated interest on approved applications. If the error relates to a disallowed deduction rather than undisclosed income, a specialist should assess whether any grounds exist to engage SARS directly outside of the standard correction process.
In all cases, acting before SARS identifies the issue independently is critical, as voluntary disclosure before detection carries significantly better outcomes than responding to a SARS initiated audit or estimated assessment. A specialist tax practitioner should be consulted immediately to assess which avenue is available and to ensure any deadlines are not missed.
