Casual Workers and Payroll in Kenya: Pay, Records and Statutory Deductions

Who counts as a casual worker in Kenya

A casual worker is engaged for work that is paid by the day or by the job rather than as a monthly salary. The defining feature is the basis of pay and the absence of a long-term commitment, not the number of hours in a particular day.

That distinction matters because the arrangement is not a way around employment obligations. Someone who works for you regularly, on your instructions and under your supervision, is on your payroll whether their wage is daily, weekly or monthly, and the way their pay is recorded should reflect that.

Arrangements that continue beyond a short period stop looking casual, and Kenyan employment law treats them accordingly. If a casual engagement has run for months, get advice and confirm the current position with the Ministry of Labour before assuming it stays casual.

Why casuals belong on payroll, not on a cash list

The cash list feels simpler, and that is its only advantage. It leaves you with no reliable record of who worked which days, no payslip, and nothing to show an inspector who asks how many people you employed last month.

Putting casual staff on payroll changes three things at once: the wage is calculated from recorded days rather than memory, the statutory deductions are applied consistently, and the resulting reports come from the same place as the rest of your payroll.

• ✓One record of days worked, rates and payments per worker.
• ✓A payslip each person can check, which prevents most pay disputes before they start.
• ✓Statutory deductions calculated the same way for casual and permanent staff.
• ✓Headcount and labour cost visibility by site, gang or department.
• ✓A defensible position if the labour office, KRA, NSSF or SHA asks questions.

Pay: daily rates, days worked and overtime

Casual pay is arithmetic on two numbers — the agreed rate and the days actually worked — which is exactly why disputes happen. A rate agreed verbally is remembered two ways, and a day recorded on a scrap of paper is a day that goes missing at month end.

• ✓Agree the daily rate in writing, and keep it with the engagement record.
• ✓Record days worked daily, not at the end of the month.
• ✓Treat piece rates the same way: what was produced, at what rate, on which days.
• ✓Apply overtime, rest-day and public-holiday treatment as the law requires, and check current rules rather than assuming.
• ✓Note when a casual becomes effectively full-time, because the basis of pay should change with it.

Statutory deductions on casual pay

Casual workers are employees, so the same statutory categories apply to what they earn: PAYE once earnings for the period pass the tax threshold, NSSF, SHIF/SHA and the Affordable Housing Levy, with the employer shares payable on top of the wage.

Because the deductions follow what was earned in the period, the days-worked record is not paperwork — it is the input to the calculation. A month with six days worked produces different figures from a full month, and the arithmetic has to follow the record rather than an assumption.

The treatment of short engagements can differ from a monthly salary, and rates, thresholds and limits change. Confirm the current position with KRA, NSSF and SHA before you finalise a period, then apply it consistently to every casual worker.

• ✓Keep a days-worked register per person, not one total per gang or site.
• ✓Calculate each worker separately, on their own earnings for the period.
• ✓Show the employer shares as a payroll cost, because they are one.
• ✓Include casual staff in the P10A employee details for the month.
• ✓Remit and file on the same deadlines as the rest of your payroll.

The records every employer should keep for casual staff

• ✓Full name and identification, with a next of kin or contact where relevant.
• ✓KRA PIN, NSSF number and SHA number, collected at engagement rather than at year end.
• ✓The agreed rate, the unit of work and the engagement date, in writing.
• ✓Days worked or units produced, signed off by the supervisor each day.
• ✓Every payment made, with the method used, so the wage and the payroll record agree.
• ✓Any deduction applied, statutory or agreed, with the amount and the period.
• ✓Statutory returns and receipts, filed with the rest of the payroll records.

Where casual payroll goes wrong

The failures are predictable, and none of them are about arithmetic.

• ✓Payments made from petty cash with no payroll entry, so the wage never appears in any return.
• ✓Statutory numbers collected months later, or never, which makes the year-end returns impossible to complete.
• ✓Attendance recorded weekly from memory, with this week’s supervisor and last week’s disagreeing.
• ✓The same worker loaded as three different names across sites, doubling the headcount and hiding the totals.
• ✓Casual staff treated as outside payroll until the labour office asks for the records.

How payroll software handles casual staff

Casual payroll is not a separate system, it is the same system with a different basis of pay. In saloPoint, casual staff are loaded once with their rate, then each period is a matter of entering the days worked, so the wage, the statutory deductions and the payslip come out of one calculation instead of three.

Because they sit in the same run as monthly employees, the reports are complete: the P9, P10 and P10A figures include every person you paid, and the bank payment file covers their net wages alongside the rest of the payroll. That is the difference between a payroll that reconciles and a cash list that cannot.

Next steps

If casual labour is a meaningful part of your workforce, the first improvement is a days-worked register; the second is getting those days into a payroll calculation rather than a calculator. saloPoint calculates casual and monthly pay in the same run, with PAYE, NSSF Tier I and Tier II, SHIF/SHA and the Housing Levy applied automatically, and it is a one-time licence from KES 20,000 rather than a monthly fee.
