Mauritania Pension Guide 2026

Overview — CNSS Pension System

The CNSS pension system covers all employees in the formal sector. The system is a defined-benefit pay-as-you-go (PAYG) scheme where current contributions fund current pensions. The old-age pension branch is funded by employee contributions of 1% and employer contributions of 6% of capped salary (total 7%). To qualify for a full old-age pension, a worker must have reached retirement age and contributed for a minimum number of years. The pension is paid monthly for life and is indexed to inflation through periodic adjustments.

Retirement Age — 60 (Standard), 55 (Early), 65 (Deferred)

The standard retirement age in Mauritania is 60. Workers may retire early from age 55, but with reduced benefits (the actuarial reduction is approximately 5% per year below age 60). Workers may also defer retirement to age 65, which increases the monthly pension by approximately 5% per year of deferral. Early retirement requires at least 20 years (240 months) of contributions. For those who have not contributed the minimum period, a lump-sum payment of total contributions may be made instead of a monthly pension.

Pension Calculation

The old-age pension is calculated using a formula based on: the average monthly salary of the best 5 years of the last 10 years of work, multiplied by the number of years of contributions, multiplied by an accrual rate (typically 1.33–2% per year). The minimum qualifying period is 10 years (120 months) of contributions for a reduced pension, or 20 years (240 months) for a full pension. The maximum pension is capped at a percentage of the reference salary. For a worker with 30 years of contributions and an average salary of MRU 50,000, the estimated monthly pension would be approximately MRU 20,000–25,000.

Survivor & Disability Pensions

CNSS provides survivor pensions to the dependents of a deceased contributor. The surviving spouse receives 50% of the deceased's pension entitlement, and each child receives 25% (up to 3 children, total maximum 100% of the deceased's pension). A disability pension is available for contributors who become permanently unable to work before retirement age. The disability pension is calculated similarly to the old-age pension based on contributions made up to the date of disability. The contributor must have at least 5 years of contributions and be assessed as at least 66% disabled by a CNSS medical board.

Pension Reform & Challenges

The CNSS pension system faces demographic and financial challenges common to PAYG schemes. The ratio of active contributors to pensioners has been declining, putting pressure on the system's sustainability. The government has considered reforms including increasing the contribution ceiling, raising the retirement age, and introducing a complementary pension scheme. As of 2026, the contribution cap of approximately MRU 60,000 per month means that high earners receive a relatively low replacement rate from the public pension and should consider additional private retirement savings.

FAQs

Can I withdraw my CNSS contributions if I leave Mauritania permanently?

Mauritania has social security agreements with certain countries that allow for the transfer of pension rights. If you leave permanently, you may be able to claim a refund of your personal contributions in certain circumstances.

How much will my pension be at retirement?

The pension depends on your average salary in the best 5 years and the number of contribution years. Given the contribution cap, the CNSS pension alone may provide a modest income. Additional private retirement savings are recommended.

Are self-employed workers covered by the pension system?

Self-employed workers are not required to contribute to CNSS but may do so voluntarily to build pension rights.
