Four Deductions, One Payslip

A payslip now carries PAYE, NSSF contributions under the tiered structure, the statutory health deduction administered by the Social Health Authority, and the affordable housing levy. Each is calculated on its own base. Some run on gross emoluments, some on pensionable pay, some are capped at an upper earnings limit that has been moving upward in phases.

Because the bases differ, the deductions do not move together. A change in how a single allowance is classified - housing, transport, a bonus, a benefit in kind - can shift one levy and leave the others untouched. Payroll systems configured before the current structure existed frequently apply the wrong base to at least one of them, and the error is invisible on the payslip because every line still looks plausible.

Most employers reconcile payroll to the bank: the net pay leaving the account matches the payroll register. Far fewer reconcile payroll to the portals, levy by levy - that the amount computed in the payroll run equals the amount declared on the return and equals the amount actually remitted.

Those three figures should be identical and often are not. A mid-month joiner processed after the return was filed, a leaver whose final dues were paid outside the payroll run, a correction posted to a prior period: each creates a difference between computed, declared and paid. Left unreconciled for a year, the aggregate is material and there is no contemporaneous record explaining any of it.

The fix is a single monthly schedule per levy with three columns - computed, declared, paid - and a stated reason for every variance. It takes an hour a month and it is the document that ends an audit conversation early.

Statutory payroll deductions are employer obligations. Where a deduction is under-remitted, the employer carries the principal, the penalty and the interest - not the employee, and not the payroll bureau, whatever the service agreement says about accuracy.

Penalties on payroll obligations generally run per month and per return. That structure matters: a small monthly under-declaration that nobody notices for two years does not produce one penalty, it produces twenty-four. The cost of the error is driven by how long it ran, not by how large it was in any single month, which is precisely why a monthly reconciliation is worth an hour.

Start with a health check rather than a back-filing exercise. Establish, for each levy, which base your payroll is actually applying and whether it matches the current requirement. Then quantify the gap across the periods still open to assessment, as principal, penalty and interest separately, so leadership sees the real number and can decide.

Only then decide the remediation sequence. Voluntary correction is almost always cheaper than an assessment, and it is a materially better conversation to have while you are the one raising it.
