What Are SIO Social Insurance Contributions, and How Do They Affect My Pay?
Bahrain's Social Insurance Organisation (SIO), the equivalent of GOSI in Saudi Arabia, deducts a percentage of your insurable salary to fund pensions, unemployment insurance, and work-injury cover. For Bahraini nationals in 2025, employees contribute 8% (7% pension plus 1% unemployment) and employers contribute 17%, a rate that's rising 1 percentage point yearly toward 20% by 2028. Non-GCC expatriates are covered for work injury only, contributing 1% against a 3% employer share.
Key facts
The specifics, before the explanation.
- 2025 employee contribution for Bahraini nationals: 8% (7% pension/old-age + 1% unemployment insurance)
- 2025 employer contribution for Bahraini nationals: 17%, rising 1 percentage point per year toward 20% by January 2028 under Law No. (14) of 2022
- Non-GCC expatriate workers: covered for work injury only, employee pays 1%, employer pays 3% (4% total)
- SIO is Bahrain's own authority; "GOSI" technically refers to the equivalent Saudi system, though the term is often used loosely across the Gulf
- From 1 March 2024, expatriate end-of-service gratuity is also funded through employer SIO contributions rather than paid directly by the employer at exit
What this actually means
The SIO deduction on your payslip funds two very different things depending on your nationality status. For Bahraini nationals, it's a full social-insurance package covering pension and unemployment insurance, which is why the rate is meaningfully higher and rising each year as part of a planned phase-in.
For non-GCC expatriates, the coverage is much narrower, essentially just work-injury insurance, which is why the contribution rate is a fraction of what Bahraini employees pay. As of March 2024, expatriates also see a portion of their eventual gratuity funded through this same SIO contribution mechanism rather than sitting entirely with the employer until termination.
Because the employer contribution rate is on a legislated glide path upward through 2028, expect this line item to change gradually rather than staying fixed, and expect employers to sometimes cite rising SIO costs as a factor in compensation or headcount discussions.
What to actually do
Rules and figures move. Confirm anything time-sensitive with the official regulator before you rely on it.
- Check your payslip for the exact SIO deduction line and compare it against your nationality status to confirm you're on the correct rate.
- Remember the employer rate is rising annually through 2028, so total on-cost of employing you is going up for your employer even if your gross pay doesn't change.
- If you're an expatriate, understand that your SIO contribution mainly covers work injury, not a pension, so don't assume it builds retirement savings the way it does for Bahraini nationals.
- Ask your employer or SIO directly for your current contribution rate before relying on any published percentage, since rates are scheduled to shift year over year.
- Confirm the latest rate directly with sio.gov.bh, since scheduled increases mean any given year's figure has a shelf life.
Frequently asked questions
Do I get a pension in Bahrain if I'm a non-GCC expatriate?
Generally no, non-GCC expatriate SIO contributions are for work-injury cover, not a pension scheme, which is why your contribution rate is much lower than a Bahraini national's.
Why is my employer's SIO contribution rate going up each year?
Law No. (14) of 2022 scheduled a 1-percentage-point annual increase in the employer contribution rate until it reaches 20% by January 2028, a planned, published phase-in rather than a one-off change.
Is SIO the same thing as GOSI?
They serve a similar function, but SIO is specifically Bahrain's authority; GOSI is the Saudi equivalent. People across the Gulf sometimes use the terms interchangeably, but they are separate national bodies.
