Remuneration structuring: cost to company versus net pay

Employers budget in cost to company. Employees experience net pay. The gap between the two is created by package structure, and it is where most remuneration disputes, failed counteroffers and surprise February payslips come from. This guide sets out the components, the statutory limits and a modelling checklist.

What actually sits inside cost to company

Guaranteed cash — basic salary and any fixed monthly cash allowance.
Employer retirement fund contribution — pension, provident or a retirement annuity arrangement.
Employer medical scheme contribution, which is a taxable fringe benefit offset by fixed medical tax credits.
Travel or car allowance, only partly included in remuneration for PAYE purposes.
Statutory employer costs: UIF (capped) and SDL where the payroll exceeds the registration threshold.
Variable pay — 13th cheque, incentive and commission, which change the annual tax picture even when monthly cash does not.

The three levers that move net pay

Only a few components genuinely change the tax outcome. Everything else is presentation.

Retirement contributions — deductible up to 27.5% of the greater of remuneration or taxable income, subject to the annual rand cap. This is the single largest legitimate lever in most packages.
Medical scheme membership — the employer contribution is a fringe benefit, but the member and dependant tax credits reduce PAYE at a fixed rand amount per month regardless of marginal rate.
Travel allowance — where a logbook supports genuine business travel, only a portion is subject to PAYE, with the balance settled on assessment.

Where structuring goes wrong

Promising a net-pay figure in an offer letter, then discovering the structure cannot deliver it after the retirement cap bites.
Reclassifying cash as an allowance without the underlying substance — SARS treats the substance, not the label.
Ignoring the annual view: a 13th cheque or incentive pushes the employee into a higher effective rate for that month and often triggers an assessment shortfall.
Forgetting that UIF is capped, so a raise on a high earner does not increase UIF but does increase SDL and retirement cost.

A modelling checklist before you sign anything

Fix the employer cost first — the CTC number the budget can carry, inclusive or exclusive of statutory costs, stated explicitly.
Model at least two structures on the current SARS tables and compare net pay, not gross.
Test the annual view including 13th cheque or incentive months.
Check the retirement deduction against both the percentage and the rand cap.
Record the assumptions with the offer, so the payslip matches the conversation in month one.

Frequently asked questions

What is cost to company in South Africa?

Cost to company (CTC) is the total annual cost the employer carries for an employee: guaranteed cash, the employer portion of retirement and medical contributions, allowances, and any other cash-equivalent benefit. UIF and SDL are employer statutory costs that sit on top of, or inside, CTC depending on how the package is defined — the definition must be stated in the contract.

Why do two employees on the same CTC take home different amounts?

Because structure changes the tax base. Retirement fund contributions are deductible up to 27.5% of the greater of remuneration or taxable income (capped annually), medical scheme fees attract fixed tax credits rather than a deduction, and travel allowances are only partly included for PAYE. Two identical CTC packages structured differently produce different net pay.

Can restructuring a package increase net pay at no extra employer cost?

Often, yes — within the limits of the Income Tax Act. Shifting cash into a deductible retirement contribution, or correcting an over-taxed travel allowance, can raise take-home pay at the same CTC. The gains are real but bounded by the statutory caps, and the change must be a genuine contractual arrangement, not a paper reclassification.

How do I model the effect before I commit?

Model it line by line on the current SARS tables. The Patuza Net Pay Simulator (NPS) shows gross-to-net for each proposed structure side by side, including PAYE, UIF, retirement caps and medical tax credits, so the employer cost and the employee's take-home are visible in the same view.

Model a package before you offer it

The Net Pay Simulator (NPS) carries any CTC structure through PAYE, UIF, retirement caps and medical tax credits on the current SARS tables, and produces a shareable gross-to-net report.
