Kenya payroll in 2026: the deductions every employer must get right

Every payroll officer knows the message. A colleague forwards a screenshot of their payslip with one line: "Please check this, it does not look right." Sometimes the employee is wrong. Often the difference is small. But when it is real, it is almost never one dramatic mistake. It is a rate that was not updated, a relief that was applied twice, or deductions taken in the wrong order, repeated quietly for months.

I have prepared monthly payroll inputs for several hundred employees across more than one country, and I led the reconfiguration and communication when SHIF replaced NHIF and when the NSSF tiers changed. The lesson is always the same. Payroll is not difficult because the rules are complicated. It is difficult because the rules change, the exceptions pile up, and nobody notices a small error until it has run for a year.

This guide is written for the business owner, finance manager or HR officer who wants to get it right. It covers the four statutory deductions, the order they must be applied in, a full worked payslip, and the practical situations where payroll actually goes wrong.

1. The four statutory deductions in 2026

Every month, an employer stands between the employee's gross pay and four statutory items. Know each one properly before you worry about anything else.

NSSF: Year 4 limits

The NSSF Act 2013 phases in higher limits over time, and Year 4 took effect in February 2026. Both employee and employer contribute 6%, in two tiers:

• Tier I: 6% of the first KES 9,000 of pay, which is KES 540.
• Tier II: 6% of pay between KES 9,001 and KES 108,000, which is up to KES 5,940.

The maximum is KES 6,480 per employee, matched by the employer, so KES 12,960 in total per employee each month. For senior staff, NSSF is now a real number in compensation planning. It also means any spreadsheet still using last year's limits is wrong for everyone earning above the old ceiling.

SHIF: flat, and uncapped

The Social Health Insurance Fund replaced NHIF from October 2024. It charges a flat 2.75% of gross salary, with a minimum of KES 300, and has no upper limit. On a KES 50,000 salary it is KES 1,375. On KES 500,000 it is KES 13,750. It is an employee deduction with no employer match.

The old NHIF habit of reading a deduction off a table is gone. SHIF is a percentage, so it moves with every pay rise and every allowance.

Affordable Housing Levy: 1.5% from each side

The levy is 1.5% of gross monthly salary from the employee, matched by 1.5% from the employer. Like SHIF, it has no ceiling. Employers often forget that the employer half is a real cost on top of the salary bill.

PAYE: progressive tax on taxable pay

PAYE is charged across five monthly bands:

Every resident employee receives a personal relief of KES 2,400 per month, which reduces the tax due. It is a credit against tax, not a deduction from taxable pay. That small distinction trips up a surprising number of spreadsheets.

Two points follow. Someone with taxable pay of up to KES 24,000 owes KES 2,400 in tax and receives KES 2,400 relief, so their PAYE is nil. They still pay NSSF, SHIF and the Housing Levy. And an employee with a second job should not receive personal relief twice, so the second employer treats that pay as secondary employment.

2. The order of operations

This is where most of the money is lost. Under the Tax Laws (Amendment) Act 2024, effective 27 December 2024, NSSF, SHIF and the employee's Housing Levy contribution are all allowable deductions before PAYE is worked out. They reduce taxable pay.

The correct sequence is:

1. Establish gross pay: basic salary, regular cash allowances, overtime, bonuses and the taxable value of any benefits in kind.
2. Compute the pre-tax statutory deductions: employee NSSF (Tier I and Tier II), SHIF at 2.75% of gross, and the employee Housing Levy at 1.5% of gross.
3. Determine taxable pay: gross pay less those deductions, and less any other deductions the law allows, such as qualifying pension contributions.
4. Compute PAYE on taxable pay: apply the bands.
5. Apply reliefs: the personal relief of KES 2,400, plus any relief the employee is entitled to and has documented.
6. Arrive at net pay: deduct the statutory amounts and net PAYE from gross, then voluntary or contractual deductions such as SACCO contributions, HELB, salary advances and loan recoveries.

3. A full payslip: KES 100,000 gross

Take an employee on KES 100,000 gross per month with no benefits in kind and no extra reliefs:

Look at the two bottom lines together. The employee takes home about KES 70,442. The business spends KES 107,550 to deliver it. That gap of roughly KES 37,000 is why a hiring budget built only on the salary figure is always short.

What the wrong order costs

Now run the same employee with PAYE calculated on the full gross pay, which is the most common mistake in a hand-built payroll:

The employee is overcharged KES 3,075 a month, or KES 36,900 a year. Across 100 employees on that salary, that is KES 307,500 a month taken from staff who did nothing wrong. When this surfaces, it does not stay a payroll problem. It becomes an employee relations problem, and it is hard to explain.

4. Where payroll really goes wrong

The formulas are the easy part. In my experience, the errors cluster in the situations around the formula.

New joiners

The first payslip is where mistakes start. Before the first pay run you need the employee's KRA PIN, NSSF number, SHA registration, bank details and, where relevant, HELB details. Chasing these in the second week of the month, under pressure, is how a new hire gets paid without deductions or with the wrong ones. A joiner who starts mid-month also needs a consistent rule for part-month pay. Decide your method, whether calendar days or working days, write it down and apply it to everyone.

Leavers

Final dues are where disputes begin. The final payslip should capture outstanding salary, accrued leave, any notice pay owed, and anything else due under the contract and the Employment Act, with the statutory deductions applied as usual. Document how each figure was reached. When a former employee claims they were underpaid, a clear calculation is your best protection.

Allowances, overtime and benefits in kind

Cash allowances and overtime are part of gross pay, so they feed into NSSF, SHIF, the Housing Levy and PAYE. Benefits in kind, such as housing, a company vehicle or a staff loan at a below-market interest rate, can carry a taxable value even though no cash changes hands. These are the items most often missed because they never appear in the bank transfer.

Reliefs and exemptions

Reliefs only work with paperwork. Build a simple process: the employee submits the document, HR checks it, a copy goes in the file, and payroll applies it from an agreed month. The common ones are:

• Insurance relief: 15% of qualifying life, health or education insurance premiums, up to KES 5,000 a month.
• Pension contributions: qualifying contributions to a registered scheme are deductible up to KES 30,000 a month.
• Mortgage interest: interest on a qualifying home loan is deductible up to KES 30,000 a month, with a certificate from the lender.
• Disability exemption: an employee holding a valid KRA exemption certificate has the first KES 150,000 of monthly income exempt from tax. Keep a copy of the certificate and note its validity period.

Retrospective changes

Pay rises and wage orders that take effect from an earlier date are a common source of error. The 2026 minimum wage order, for example, is deemed to have taken effect on 1 May 2026, so payroll had to pay arrears and move forward at the same time. Arrears affect every deduction that follows gross pay, and they can push someone into a higher band for that month. Work them through the full sequence, not as a simple top-up.

Rate changes

NSSF changed in February. The minimum wage changed in May. SHIF replaced NHIF in October 2024. Rates change more often than people expect, and every one of those changes touches every payslip. The question to ask is not whether your rates are right today. It is how fast and how safely you can change them when the law moves.

5. Deadlines and reconciliation

Payroll compliance is as much about timing as arithmetic.

• PAYE, SHIF and NSSF are due by the 9th of the following month.
• The Housing Levy is due by the 9th working day after the end of the month, so its date shifts with weekends and public holidays.
• Late payment attracts penalties and interest, and the amounts differ between authorities. Check the current rates in each authority's notices rather than relying on a number remembered from last year.

Then reconcile before you pay. Compare your payroll register against the KRA P10 return, the SHA portal and the NSSF portal. If your register says one thing and an authority's system says another, find out why before an inspector asks.

6. A month-end checklist

This is the sequence I would run before releasing any payroll:

1. Confirm all joiners, leavers, promotions and salary changes for the month are recorded and approved.
2. Confirm overtime, bonuses, allowances and deductions have been entered and signed off.
3. Check that every rate and threshold in use matches the current law.
4. Run the payroll and compare it with last month, line by line.
5. Investigate any employee whose net pay moved by more than you can explain.
6. Reconcile the register to the statutory returns before payment.
7. Have someone other than the preparer review and approve.
8. Keep the working papers, so you can show how every figure was reached.

If a step feels like a luxury when you are busy, that is usually the step that would have caught the error.

7. Common questions

Do employees on low pay pay PAYE?

An employee whose taxable pay is KES 24,000 or less per month owes no PAYE after personal relief. They still pay NSSF, SHIF and the Housing Levy, and the employer still pays its share.

Can the employer simply absorb the employer-side contributions?

The employer share of NSSF and the Housing Levy is a separate cost on top of salary. It must not be taken out of the employee's pay.

Is a spreadsheet good enough?

For a very small team with stable pay, a well-controlled spreadsheet can work. Its weakness is not the arithmetic. It is that rates are typed into many cells, changes are not recorded, and one person can alter anything. As the headcount grows, the cost of an unnoticed error grows faster than the cost of a proper system.

How often should we review our payroll set-up?

At least whenever a statutory rate changes, and once a year regardless. A short review before each financial year can save months of corrections.

Figures in this article are as published at the time of writing, 13 October 2026. Always confirm current rates with KRA, NSSF and SHA before filing.
