Personal Relief Is Claimed Once: The Second-Job Problem

A Small Number With a Long Tail

Personal relief in Kenya is KSh 2,400 a month — 28,800 a year. It is a modest figure, and it is the source of one of the more uncomfortable payroll conversations an HR team can have.

The rule is simple: relief is claimed once per taxpayer, not once per employment. It reduces the tax charged, not the taxable pay, and a person is entitled to it once regardless of how many employers they have.

What Goes Wrong

An employee takes a second job — a part-time role, a consultancy put through payroll, a directorship at a related company. Both employers run payroll correctly by their own lights. Both apply the monthly relief.

The employee has now claimed 4,800 a month against a single entitlement of 2,400. Over a year that is 28,800 of tax that should have been paid and was not.

Nobody has done anything obviously wrong. Neither employer knows about the other. And the shortfall is assessed against the employee, who had no idea it was accumulating and who has, in the meantime, spent it.

Whose Problem It Becomes

Legally the under-deduction follows the taxpayer. Practically it arrives in the HR office, because the employee's first reaction on receiving an assessment is to ask why their employer got their payroll wrong.

The conversation is difficult precisely because the answer is unsatisfying. The payroll was not wrong. It was correct in isolation and incorrect in aggregate, and there was no mechanism by which either employer could have known.

Handling It Properly

The mechanism that exists is the secondary employment designation. Where an employee has a primary employment claiming the relief, the secondary employer should not apply it. The tax on the secondary employment is then calculated without relief, and the aggregate is right.

This requires two things that are easy to skip.

Asking the question at onboarding. "Is this your only employment?" is a single field on a starter form, and it is the entire fix. Ask it once, record the answer, and configure the payroll accordingly. Left unasked, the default assumption is always that the job is the only one — which is right most of the time and expensive when it is not.

A payroll system that can suppress relief for an individual. This sounds obvious and is not universally true. A system that applies relief as a global constant, with no per-employee override, cannot handle a secondary employment at all.

The Same Applies to Non-Residents

Personal relief is available to resident individuals. A non-resident employee is taxed without it, and at the appropriate rates for their status.

This is a second per-employee override, and a payroll that cannot switch off relief for a secondary employment usually cannot switch it off for a non-resident either. The two problems have the same root and the same fix.

What to Check in Your Own Payroll

Does your starter form ask about other employments? If not, add the question. It costs nothing and it is the only point at which the information is naturally available.

Can relief be suppressed for an individual employee? Try it. If the only way is to edit a global setting, the system cannot represent the situation.

Do you know which of your staff hold directorships elsewhere? This is a common blind spot. A directorship at a sister company, put through that company's payroll, is a second employment even when everyone involved thinks of it as one job.

Is relief being subtracted from the tax, or from the taxable pay? It reduces the tax charged. Applying it to taxable pay instead produces a different, wrong answer that is easy to overlook because it moves the net in the expected direction.

Worth Raising Before It Is Discovered

The kindest version of this conversation happens early. An employee told at onboarding that their second job will be taxed without relief understands why their net is lower and plans around it. The same employee told eighteen months later, by way of an assessment, has a legitimate grievance about not having been told.
