SHIF Contribution 2026: How 2.75% of Your Salary Is Calculated
Your SHIF contribution in 2026 is 2.75% of your gross monthly salary, with no upper limit and a minimum of KES 300, and here is exactly how it is calculated and deducted. The Social Health Insurance Fund (SHIF) replaced NHIF in October 2024, and the biggest change is simple: instead of the old fixed bands, you now pay a flat percentage of what you actually earn. The more you earn, the more you pay, with no ceiling to cap it.
The quick answer: how SHIF is calculated
SHIF is 2.75% of your gross monthly salary. Your final contribution is the higher of two figures: 2.75% of gross pay, or KES 300, whichever is larger. There is no maximum, so a high earner pays 2.75% of their full salary no matter how large it is. The deduction is made by your employer every payroll cycle and remitted to the Social Health Authority by the 9th of the following month.
The formula is straightforward:
SHIF = Gross monthly salary × 2.75% (or KES 300 if that result is lower)
What counts as “gross salary”
This is where most people get the number wrong. SHIF is calculated on gross pay, not net pay, and it includes your basic salary plus cash allowances such as housing, transport, and hardship allowances. It is not calculated on what lands in your account after deductions.
A few rules worth knowing:
- Use gross, not net. Applying 2.75% to your take-home pay is the most common error and gives the wrong figure.
- Cash allowances are included. Taxable cash allowances form part of the base.
- Non-cash benefits are excluded. Benefits in kind do not count toward the SHIF base.
- The whole 2.75% is yours. Unlike the Housing Levy, where employer and employee each pay 1.5%, SHIF is borne entirely by the employee. The employer only deducts and remits it.
Worked examples across salary levels
The table below shows how the calculation plays out. Note where the KES 300 minimum takes over at the lowest end.
| Gross monthly salary (KES) | 2.75% calculation | SHIF payable (KES) | Rule applied |
|---|---|---|---|
| 10,000 | 275 | 300 | Minimum (KES 300) |
| 20,000 | 550 | 550 | Percentage |
| 50,000 | 1,375 | 1,375 | Percentage |
| 100,000 | 2,750 | 2,750 | Percentage |
| 120,000 | 3,300 | 3,300 | Percentage |
| 300,000 | 8,250 | 8,250 | Percentage (no cap) |
The KES 300 floor matters only for very low earners. For almost everyone in formal employment, the 2.75% figure is what applies, and it keeps rising with salary because nothing caps it. This is the sharpest break from NHIF, which capped out at KES 1,700 a month regardless of how much you earned.
SHIF lowers your taxable income
One detail that softens the blow: SHIF is a pre-tax deduction. It is subtracted from your gross salary before PAYE is calculated, the same way NSSF and the Housing Levy are. That means it reduces the income your tax bands apply to, giving you a small indirect tax saving.
The order on a Kenyan payslip is:
Taxable income = Gross salary − NSSF − SHIF − Housing Levy
So while 2.75% leaves your pay, you do not also pay PAYE on that slice. The net cost to you is slightly less than the headline figure suggests.
When and how it is remitted
For salaried employees, you do not pay SHIF yourself. Your employer deducts it and remits it to the Social Health Authority by the 9th day of the following month, alongside PAYE on iTax. So October’s deduction is due by 9 November.
Late remittance is treated seriously. Contributions paid late attract a penalty of 2% of the unpaid amount for every month it stays outstanding, and the liability for unremitted deductions falls on the employer. If your contributions lapse, your access to SHA-covered services can be affected, which is why checking your payslip each month matters.
What to do as an employee
A short checklist to stay on top of it:
- Check your payslip. Confirm the SHIF line equals 2.75% of your gross, or KES 300 if you are a low earner.
- Confirm it is on gross, not net. If the figure looks too low, your employer may be calculating it on the wrong base.
- Keep your payslips. They are your proof of contribution if there is ever a dispute about coverage.
- Raise mismatches early. A wrong deduction is easier to fix in the same month than months later.
- Make sure you are registered. You need an active SHA registration to actually use the cover your contributions buy.
The bottom line
SHIF in 2026 is simple in principle and tied directly to your earnings: 2.75% of gross, a KES 300 floor, no ceiling, deducted before tax, and remitted by your employer by the 9th. The single most useful habit is to glance at your payslip each month and confirm the number is calculated on your gross salary, because that one check catches the most common and costly mistake.
