Cellphone and Internet Allowance Tax in South Africa

A cash cellphone or data allowance is remuneration. It is added to your taxable income, taxed at your marginal rate, and has PAYE deducted from it every month, with no automatic business deduction to set against it. An employer-provided phone or device that you use mainly for the employer's business is treated the other way: SARS places no value on it under the Seventh Schedule, so it adds nothing to your tax. What separates the two outcomes is ownership. Cash paid to you is your income to spend; a phone the employer owns and controls stays the employer's equipment.

A cash allowance is taxed in full

When your employer pays you a fixed cellphone or data allowance in cash, that money is part of your remuneration. Your employer includes it in the amount on which monthly employees' tax (PAYE) is worked out, it appears on your IRP5, and it forms part of the income assessed when you file on eFiling.

Nothing reduces it automatically. A travel allowance, by contrast, has a partial PAYE exclusion and a deemed-cost claim you can make against business kilometres recorded in a logbook. A cellphone allowance has no such machinery: no deemed-cost table, no fixed no-value rule, and no built-in split between business and private use, so the full allowance is taxed. A salaried employee also cannot simply write off the airtime spent on work calls, because deductions against salary income are tightly restricted. In practice the whole allowance is taxed and nothing comes back.

An employer-provided phone can carry no value

The Seventh Schedule to the Income Tax Act values benefits in kind, and for some of them it sets the value at nil. Two of those no-value rules cover communication equipment and communication services.

• Right of use of an asset (paragraph 6(4) of the Seventh Schedule): where the asset is telephone or computer equipment that the employee uses mainly for the purposes of the employer's business, no value is placed on the private use.
• Free or cheap services (paragraph 10(2)(bA)): a communication service provided to an employee has no value where the service is used mainly for the purposes of the employer's business.

Read together, a work phone that the employer owns plus a contract for airtime or data that the employer pays, both used mainly for work, make up a nil-value fringe benefit. Nothing is added to your remuneration for them and nothing runs through PAYE. Everything turns on the word "mainly": the dominant use has to be for the employer's business, and incidental private calls on that phone do not create a taxable value.

The mechanism is what differs. Cash in your hand is taxed because it is your income. A device and service the employer provides and controls, used mainly for its business, count as a tool of trade, so the schedule sets the value at nil.

A worked example

Take an employee whose taxable income for the 2026 year of assessment (1 March 2025 to 28 February 2026) is R450,000 before any phone arrangement. That figure sits in the R370,501 to R512,800 band, where the tax is R77,362 plus 31% of the amount above R370,500, so the marginal rate is 31%.

Case A is a cash cellphone allowance of R1,000 a month.

• Annual allowance: R1,000 x 12 = R12,000
• Taxable income becomes R450,000 + R12,000 = R462,000, still inside the 31% band.
• Tax on R450,000: R77,362 + 31% x (R450,000 - R370,500) = R77,362 + 31% x R79,500 = R77,362 + R24,645 = R102,007
• Tax on R462,000: R77,362 + 31% x (R462,000 - R370,500) = R77,362 + 31% x R91,500 = R77,362 + R28,365 = R105,727
• Extra tax from the allowance: R105,727 - R102,007 = R3,720

That matches R12,000 x 31% = R3,720, because the whole allowance is taxed at the marginal rate. The primary rebate makes no difference to the gap: it is a fixed amount subtracted in both calculations, so it cancels out.

Case B gives the same employee a company phone on a company contract, used mainly for work, instead of the cash.

• Value added to remuneration: R0
• Extra tax: R0

Same employee, same job. The only tax difference is how the phone was arranged. The R1,000 cash allowance costs R3,720 in tax over the year; the employer-provided phone used mainly for work costs nothing.

Keep it separate from home office and travel

This rule is only about communication equipment and services. It is not the home-office deduction, which is about the running costs of a dedicated workspace, and you can check whether that one applies in the note on whether salaried employees can claim a home office. It is also not a travel allowance, which is about a private vehicle and is set out in the travel allowance tax guide. A company phone is closest in logic to a company car fringe benefit, since both are employer assets valued under the Seventh Schedule, though a phone used mainly for work lands at nil where a car does not.
