AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
The SARS 183-day rule is the foreign employment income exemption in section 10(1)(o)(ii). A South African tax resident employee who works outside SA for more than 183 full days in a 12-month period, including more than 60 continuous days, can have the first R1.25 million exempted. Fees paid to independent contractors are excluded, so most short consultancy contracts in Nigeria stay taxable in South Africa.
The short version
South Africa taxes its residents on worldwide income. If you are tax resident in South Africa and take a contract in Nigeria, the money you earn there is, as a starting point, part of your South African taxable income. The question people search for, the "183-day rule", is really about one exemption in the Income Tax Act, section 10(1)(o)(ii), which SARS calls the foreign employment income exemption. It can remove part of that income from SA tax, but only when three conditions all hold: you are an employee, you spend more than 183 full days rendering services outside South Africa in a 12-month period, and more than 60 of those days are continuous.
For most Nigerians in South Africa doing a short contract at home, the first condition is the one that fails. A short contract is often paid as a consultancy or freelance fee, and SARS states plainly that income received by independent contractors falls outside the exemption because it is not remuneration.
First question: are you a South African tax resident?
The exemption only exists for residents; SARS says it "does not apply to non-residents". SARS uses two tests, set out on its Tax and non-residents page (last updated 19 August 2026):
- Ordinarily resident: South Africa is the country you would naturally and as a matter of course return to, your real home.
- Physical presence: more than 91 days in South Africa in the current tax year, more than 91 days in each of the five preceding tax years, and more than 915 days in total over those five years.
A Nigerian on a work permit who has lived in Johannesburg for three years may not yet meet the physical presence test, and whether South Africa is their "real home" is a question of facts. If you are not resident, SARS taxes you only on South African-source income, and a contract performed in Nigeria for a Nigerian client is, in general, not South African source. The SARS page on residence tests is the place to start; our guide to the SARS residence test for Nigerians goes through the tests in more depth.
SARS also notes that someone who is outside South Africa for a continuous period of at least 330 full days stops being treated as resident from the day they left. A short contract will not trigger that, but a long posting can.
The exemption, condition by condition
| Condition (SARS wording) | What it means for a Nigeria contract |
|---|---|
| Services rendered outside SA for "longer than 183 full days in any 12-month period" | Count full days working outside South Africa. A six-week contract will not reach 183. |
| Outside SA for "a continuous period exceeding 60 full days" in that period | At least one unbroken stretch of more than 60 full days away. |
| Income is employment remuneration | Contractor and consultancy fees are excluded. |
| Only the first R1.25 million qualifies (years of assessment from 1 March 2020) | Income above that is taxed at normal rates, with a possible foreign tax credit. |
| Resident taxpayers only | Non-residents are taxed on SA-source income only, so the exemption is not needed. |
The 183 days do not need to be spent in Nigeria alone. They are days outside South Africa rendering services. SARS refers readers to Interpretation Note 16 for how days are counted, including part days; read it before relying on a borderline count.
If you are employed versus contracting
Employed by a Nigerian or South African employer
If a Nigerian company puts you on its payroll for a long assignment, or your South African employer seconds you to Nigeria, the income is remuneration. If you clear the 183-day and 60-day conditions, the first R1.25 million is exempt in South Africa. Your employer can, at its discretion, ask SARS for a directive to reflect a foreign tax credit monthly, according to the SARS page.
Paid as a contractor or freelancer
Most short contracts in Nigeria are invoiced: you sign a service agreement, issue an invoice and are paid a fee. That income sits outside section 10(1)(o)(ii). It is taxed in South Africa as part of your income if you are resident, and Nigeria may also tax it at source. Relief for double tax then comes through a foreign tax credit under section 6quat, claimed on assessment in your income tax return, "provided certain requirements are met". Keep the Nigerian tax deduction evidence, because you will need it to claim.
A worked example
Example only, simplified. Ada is tax resident in South Africa. Between 1 March and 31 August she spends 140 full days in Lagos on a project, comes home for two weeks, then returns for another 50 full days. That is 190 days outside South Africa, and the first stretch of 140 days is well over 60 continuous days.
- If Ada was employed by the Lagos company for the assignment and earned the equivalent of R900,000, the full amount is within the R1.25 million cap and can qualify for the exemption.
- If Ada invoiced the same R900,000 as a consultant, the exemption does not apply. The R900,000 goes into her SA return; any Nigerian tax withheld may support a section 6quat credit.
- If Ada stayed only 120 days in total, she fails the 183-day test whatever her status, and the income is fully taxable in South Africa.
What to check first
- Are you SA tax resident this year? Apply the two SARS tests to your own dates.
- Is the contract employment or a service agreement? Read the document, not the job title.
- Count full days outside South Africa in any 12-month period, and find your longest continuous stretch.
- Keep flight records, passport stamps and the contract. SARS can ask for them.
- Ask the Nigerian payer whether it will withhold Nigerian tax, and get the receipt or credit note.
Where Pryme fits
If the Nigerian client pays you in naira or dollars, a Pryme account can receive naira on local Nigerian details and hold USD, GBP and EUR, so the fee does not have to be converted the day it lands. Swap converts only when you choose, with the rate shown first. See multicurrency business accounts and invoicing.
Questions people ask
Does the 183-day rule apply to freelancers in South Africa?
No. SARS says income received by independent contractors is excluded from section 10(1)(o)(ii) because it is not remuneration.
Do the 183 days have to be in one country?
No. The test counts full days rendering services outside South Africa, with more than 60 of them continuous.
What is the cap on the foreign employment income exemption?
The first R1.25 million of foreign employment income, for years of assessment from 1 March 2020. Income above that is taxed at normal rates.
Can I get credit for Nigerian tax paid?
SARS allows a foreign tax credit under section 6quat, claimed on assessment through your income tax return if the requirements are met.
