South Africa — Foreign Employment Income Exemption, s 10(1)(o)(ii)

The single most misunderstood point. The exemption is not "the first R1,250,000 of foreign remuneration is exempt". SARS applies a work-day ratio to the foreign-service remuneration first, and caps the result second. On most facts the ratio binds long before the cap does, and a return prepared on the "first R1.25m" assumption will overstate the exemption, sometimes by a very large amount.

Section 2 — Three quantities, three different jobs

Almost every error in this area is a confusion between these three. They are not alternatives; all three apply, in order.

Quantity	What it is	What it does
Full days outside the Republic	More than 183 days in aggregate, and a continuous period of more than 60 full days, in any 12 consecutive months	The gate, and only the gate. It decides whether the exemption is available at all. It never touches a rand of the calculation.
Work days outside ÷ total work days	The apportionment ratio	The money. It determines how much of the remuneration is exempt.
R1,250,000	The statutory ceiling per year of assessment	Applied last, to the result of the ratio.

A taxpayer can pass the gate comfortably and still receive a small exemption, because the gate and the money are computed from different things.

Section 4 — The IRP5 must carry the remuneration UN-apportioned

This is where the largest errors are made, and they are made by the employer, before the practitioner ever sees the certificate.

SARS applies the ratio to whatever the foreign-service codes disclose. If the employer has already apportioned the remuneration before coding it, the remuneration is apportioned twice — once by the payroll, once again by SARS — and the exemption collapses.

So the foreign-service codes must carry the remuneration for the assignment period in full, un-apportioned, and let the SARS ratio do the work. That is how Interpretation Note 16's own worked example behaves.

Practical consequence: an under-coded certificate silently caps the taxpayer out below the statutory limit, and no amount of correct work on the return will recover it. Where the coding is wrong, the fix is a corrected IRP5 from the employer, not a re-computation. Check the certificate before doing anything else.

Section 5 — Choosing the twelve month window

The period is any 12 consecutive months. It need not be the year of assessment, and choosing it deliberately is part of the work.

An assignment that straddles a year end will often produce a comfortable margin on one window and a dangerous margin on another. A window giving 185 days against a 183 day requirement is a margin of two days — one contested border stamp from failing. Shifting the window to capture a tour that crosses the year end can turn that into a margin of several weeks on identical underlying facts.

Test more than one window before settling. Record which window was used and why.

Section 6 — Counting full days

A full day outside the Republic is a day spent wholly outside it. Both the departure day and the return day are therefore excluded from the count.

• Overnight flights. Where the RSA exit stamp and the foreign entry stamp fall on different dates, the arrival day is a full day abroad. Where the flight departs and lands on the same date — common on short regional hops — only one day is lost.
• Foreign-to-foreign travel. A day spent travelling between two foreign countries is a full day outside the Republic. The absence is not broken by transiting a third country.
• Evidence. Build the count from passport stamps, boarding passes and the assignment schedule, date by date. A count asserted from memory will not survive verification.

Section 7 — Work days are not automatically Monday to Friday

The ratio uses days on which services were actually rendered, not a calendar weekday proxy.

For many assignments the two are close enough. For others they are not: touring professionals, shift workers, events staff and anyone on duty for the whole of a deployment routinely render services at weekends. Applying a weekday proxy in those cases can understate the foreign work days by a third or more, and understate the exemption in the same proportion.

Build the date-by-date schedule of days actually worked, inside and outside the Republic, and use it for both the numerator and the denominator.

Section 8 — ITR12 containers

Field	What it is	Use it?
4041	The s 10(1)(o)(ii) exempt amount	✅ This is the claim field.
4033	The s 10(1)(o)(i) container — officers and crew of ships	❌ A different, uncapped exemption. Not this one.
4587	An IRP5 information code	❌ Not a claim field.
4259	Foreign income not reflected on a South African IRP5	Mandatory. Enter 0 where all foreign remuneration is on an SA IRP5.

Placing the claim in the wrong container is a common cause of a verification request even where the underlying computation is correct.

Section 9 — Edge cases

• Passing the gate does not size the exemption. Treat them as separate questions and compute them separately.
• The cap is per year of assessment, applied after the ratio, not before.
• Employees only. An independent contractor cannot use this section, whatever the contract is called. Test the relationship, not the label.
• Residency first. A non-resident has no need of this exemption; a resident who has ceased residency mid-year has a different problem. Settle residency before computing.
• A double tax agreement may give a better result than s 10(1)(o)(ii) on the same facts. Where a DTA applies, compare the two before claiming.
• Where the exemption is partial, the non-exempt balance stays in gross income and is taxed normally, and s 6quat foreign tax credit relief may apply to it.

Section 10 — Self-checks

1. Compute the ratio threshold. R1,250,000 ÷ foreign-service remuneration. If the work-day ratio is below that number, the cap is not the operative limit — the ratio is. Stating the exemption as R1,250,000 in that case is wrong.
2. Check the certificate for double apportionment. Does the foreign-service remuneration on the IRP5 look like it has already been reduced by a time ratio? If so, applying the SARS ratio again understates the exemption. Get it corrected.
3. Test a second twelve month window before accepting a thin margin on the day tests.
4. Reconcile the day counts. Work days outside plus work days inside must equal total work days. Full days outside is a different count and will not tie to it.
5. Confirm the container is 4041, and that 4259 carries a figure.
