Why Social Security Levies in Africa Can Trip You Up

When sending expatriates into African countries, most companies diligently account for local income tax obligations and potential double taxation relief. However, one area that often slips through the cracks is the host country’s social security or pension contributions.

These levies can be significant, frequently mandatory even for short-term assignments, and in many cases apply from day one. Failing to include them in your cost modelling or compliance processes can lead to unexpected expenses, or worse, non-compliance.

Home Country Reliefs Cover Income Tax, Not Social Security

When an employee works abroad, their home country may still consider them liable for tax and social security contributions. While many countries provide income tax relief through double taxation treaties or foreign employment exemptions, such relief almost never extends to social security obligations.

This means expatriates (and their employers) can end up contributing in both the home and host countries unless a specific social security agreement exists between them and in Africa, such agreements are rare.

The South African Example 

A good illustration is South Africa’s foreign employment income exemption under section 10(1)(o)(ii) of the Income Tax Act.

This exemption allows South African tax residents to exclude foreign employment income up to R1.25m from South African tax if they spend more than 183 days outside South Africa in any 12-month period, including at least 60 consecutive days. From 1 March 2020, the exemption is capped at R1.25 million per year.

However, this exemption applies only to income tax. It does not remove the obligation to contribute to social security or pension schemes in the country where the person works. Even if income is exempt in South Africa, the host country’s social security liabilities still apply.

If the South African leaves the medical aid society while working outside the country, he or she may face increased contributions when the return to South Africa, to make up for the period they did not contribute. This can happen if they were covered by an international health insurance policy while outside South Africa.

Social Security in Africa: Easy to Overlook, Hard to Avoid

Social security and pension systems vary widely across Africa, but the common thread is that contributions are usually compulsory for all employees, including expatriates. Here are two examples that illustrate the point.

Kenya:

Employers and employees must both contribute 6% of pensionable earnings to the National Social Security Fund (NSSF), a total of 12%. The system has lower and upper earnings limits, which cap the contributions but still make them material for higher-earning staff. Even short-term expatriate employees are generally required to contribute unless the employer has an approved occupational scheme that replaces the NSSF.

Ghana:

In Ghana, the combined social security contribution is 18.5% of basic salary, split 5.5% for the employee and 13% for the employer. Expatriate employees are required to contribute unless a narrow exemption applies. Employers are responsible for registering and remitting contributions, and expatriates who leave Ghana permanently may claim an emigration benefit refund.

These rates are much higher than in many developed countries, and because they are often overlooked in assignment costings, they can significantly inflate total employment costs once discovered.

In some cases, it is possible to obtain a refund from the social security or pension scheme when an individual leaves the country. However, this is sometimes delayed until retirement age, and some countries allocate the entire contribution for a foreign national or expat to a reserve account rather than the individual’s account with the scheme, so that no refund is possible. Uganda’s National Social Security Fund (NSSF) is an example of this, for short term expats who are in the country for less than 3 years.

How Companies Get Caught Out

There are several recurring themes when expatriate assignments go wrong from a cost or compliance standpoint:

High combined rates: In many African countries, the total employer and employee contribution can reach 15–20% of salary, or even higher in some countries.

Immediate applicability: Obligations often arise from the first month of local employment, even for short-term projects.

No relief from home country: Few countries have social security treaties with African states, so contributions in Africa are rarely creditable or exempt back home.

Changing thresholds: Wage ceilings, contribution rates, and rules change regularly, sometimes annually.

Poor visibility: HR and payroll teams may assume that “tax covered” equals “compliance complete,” which is rarely the case.

What to Do Before Moving Staff

1. Model total costs accurately: include both income tax and all statutory contributions in your host country payroll assumptions.
2. Check home country obligations: confirm whether the employee remains liable for home country social security while abroad.
3. Clarify assignment structure: whether the employee is on local hire, secondment, or international assignment affects liability.
4. Ensure proper documentation: contracts, payslips, proof of contributions, and days spent abroad all need to be retained.
5. Review regularly: update your models for legislative changes, new ceilings, or rate adjustments.
6. Engage local experts: in many African jurisdictions, local payroll advisers or employer-of-record providers are essential for correct registration and compliance.

A Typical Scenario

A company in South Africa sends an employee to Ghana for nine months. The employee meets the conditions for the South African foreign employment income exemption and expects not to pay tax in South Africa on that income.

However, the employer must still register the employee with Ghana’s Social Security and National Insurance Trust (SSNIT) and contribute 13% of salary, while the employee contributes 5.5%. None of these payments are creditable in South Africa, so the total employment cost increases substantially something that could have been avoided with proper planning.

Key Takeaways

• Social security levies in Africa are substantial and easily overlooked.
• Income tax exemptions and double tax treaties do not cover them.
• Many African countries apply social security obligations from the first month of employment, even for expatriates.
• Budgeting, documentation, and local compliance support are essential to avoid surprises.
• See if it is possible to obtain a repayment from the scheme when the expat leaves the country.

In short: don’t let social security trip you up. Build it into your planning, budgeting, and compliance strategy from the outset, and you’ll avoid both unexpected costs and unpleasant audits.
