Difference Between CapEx and OpEx: A South African Guide

SME owner reviewing a production machine purchase

You buy a R12,000 laptop and pay R900 for a monthly software subscription. Both are business costs, but they land in completely different places in your books and your tax return. The difference between CapEx and OpEx comes down to this: CapEx (capital expenditure) buys something that serves your business for years, so it goes on the balance sheet and is written off over time. OpEx (operating expenditure) keeps the business running day to day, so it hits the income statement straight away.

Get the split wrong and your profit looks better or worse than it really is, your SARS deductions can be challenged, and a bank or investor reading your financial statements may draw the wrong conclusions. This guide keeps it practical, with South African examples.

TL;DR

  • CapEx is money spent on assets that last (equipment, vehicles, property, major software builds). It sits on the balance sheet and is expensed gradually through depreciation.
  • OpEx is the cost of running the business (rent, salaries, utilities, subscriptions). It is expensed in the period you incur it.
  • For tax, SARS generally allows OpEx as a deduction under section 11(a), but not expenditure of a capital nature. Capital assets usually earn a wear-and-tear allowance under section 11(e) instead.
  • Many businesses set an internal capitalisation threshold so small purchases are not treated as assets. Whatever you choose, apply it consistently.
  • Keep proof of what you paid and what the asset was worth. SARS and the courts care about evidence, not labels.

CapEx and OpEx in plain language

Think of a coffee shop in Rosebank. The espresso machine will work for years: that is CapEx. The coffee beans, the milk, the rent and the baristas’ wages are used up as the shop trades: that is OpEx.

The working test is simple. Ask two questions:

  1. Will this give my business a benefit for more than one financial year?
  2. Is it buying, building or materially improving an asset, rather than keeping things running?

Two yeses point to CapEx. Otherwise it is almost always OpEx.

The Treasury’s own guide on separating current from capital spending uses the same logic: it sets rules for deciding whether spending linked to capital assets is capital or current in nature. That guide is written for government, but the thinking carries over to any business.

Side-by-side comparison

CapEx OpEx
What it buys Long-lasting assets Day-to-day running costs
Typical examples Machinery, vehicles, buildings, computers, major software development Rent, salaries, electricity, internet, marketing, repairs
Where it appears Balance sheet (as an asset), then depreciation on the income statement Income statement immediately
Effect on profit Spread over the asset’s useful life Reduces profit in the period incurred
Cash flow statement Investing activities Operating activities
SARS treatment (general) Not deductible under s 11(a); wear-and-tear allowance may apply under s 11(e) Deductible if incurred in the production of income and not of a capital nature

If you want to see how OpEx and depreciation feed into profit, our guide to income statements for South African businesses walks through it line by line.

Examples from a South African business

Typical CapEx

  • A delivery bakkie for a Randburg courier start-up
  • A CNC machine or oven in a Rustenburg workshop
  • A server, or a fleet of laptops for a growing Cape Town agency
  • Building a custom client portal or app that will serve the business for years
  • Renovating premises in a way that extends their life or capacity

Typical OpEx

  • Office or shop rent
  • Salaries and wages
  • Electricity, water, data and airtime
  • Cloud subscriptions and software licences paid monthly
  • Marketing, fuel, stationery, insurance
  • Routine repairs and servicing

The grey areas

Are staff CapEx or OpEx? Salaries are OpEx. The exception is when your own people build an asset. Under IAS 16, costs such as employee benefits, site preparation and professional fees can be capitalised only when they are directly attributable to getting the asset to its location and working condition. Once it is up and running, later costs are normally expensed.

Is a laptop CapEx or OpEx? It depends on your policy. A laptop lasts years, so in theory it is an asset. In practice, many businesses expense low-value items straight away to avoid tracking dozens of tiny assets. For tax, SARS has addressed this in the home-office context: a laptop bought for R12,000 and used for trade could qualify for a wear-and-tear allowance under section 11(e) if the criteria are met.

Repairs versus improvements. Fixing a leaking roof is OpEx. Replacing the whole roof with a bigger structure is CapEx. The question is whether you restored what you had or created something better or longer-lasting.

Software. A monthly subscription is OpEx. A one-off build of custom software you will use for years leans towards CapEx. This is one reason cloud tools have changed how businesses budget: capital outlay turns into a predictable monthly cost.

Where do you draw the line? Capitalisation thresholds

Nobody wants a R150 stapler on the asset register. That is why businesses set a threshold: below it, spend is expensed; above it, spend is capitalised.

The National Treasury’s guide gives a public-sector example: stand-alone items such as computers or tools costing less than R5,000 are classified as current expenditure, whatever their useful life. That figure binds government departments, not your private company. But it is a useful reference point, and the same guide stresses that you should decide whether an item is stand-alone or part of a larger project and use consistent cut-offs.

For a private business, practical rules look like this:

  1. Pick a threshold that suits your size. A R2,000 limit makes sense for a small agency; a manufacturer may use a higher one.
  2. Write it down in a short accounting policy.
  3. Treat items bought together as one project. Ten desks bought for a new office are one purchase, not ten small ones.
  4. Apply the rule every year. Changing it to flatter a single year’s profit is how disputes begin.

Your annual financial statements should reflect that policy. If you are unsure how your numbers will read to a lender or investor, our guide on how to analyse financial statements shows what they look for.

How SARS treats CapEx and OpEx

OpEx: the section 11(a) deduction

Section 11(a) of the Income Tax Act allows a deduction for expenditure actually incurred in the production of income, provided it is not of a capital nature. That last phrase is why the CapEx/OpEx question matters for tax, not just for presentation.

CapEx: allowances instead of a straight deduction

Because capital spending is not deductible under section 11(a), the law gives relief another way. In a High Court judgment, the court noted that through section 11(e) the legislature recognised relief for capital expenditure on assets that diminish in value through use. That is the wear-and-tear allowance.

SARS publishes Interpretation Note 47, which explains the value on which the allowance is based and includes a schedule of write-off periods SARS accepts for different assets. Your accounting depreciation and your tax allowance are often different numbers, and your accountant reconciles the two.

For our own plain-English take on the accounting side, see our article on depreciation for South African SMEs.

Evidence matters

In the same judgment, the taxpayer had to prove the market value of the assets at the date of acquisition, and book value alone was not enough. This matters most when you buy second-hand equipment or buy from a related company. Keep invoices, valuations and proof of payment. Calling something “capital” in your ledger does not secure the allowance.

CapEx, OpEx and VAT

VAT adds a layer. If you are a registered VAT vendor, input tax on both CapEx and OpEx can generally be claimed when the purchase is for making taxable supplies. Trouble starts when costs serve both taxable and exempt activities. SARS guidance says input tax must be directly attributed to the intended purpose of the expense, and mixed-use costs need an apportionment formula. That ruling is written for municipalities, so treat it as an illustration of the principle and ask your accountant how it applies to your set-up.

If you are close to the registration threshold, or thinking about registering because of a big equipment purchase, read our VAT registration guide for SA SMEs first.

Why the split matters beyond tax

Profit. Expensing a R300,000 machine in one month makes that month look like a disaster. Capitalising it spreads the cost across the years it earns money.

Cash. Profit and cash are different. A business can be profitable on paper while a large CapEx outlay drains the bank account. Track both.

Funding. Lenders and investors read the balance sheet and the cash flow statement. Heavy CapEx can signal growth or over-commitment, depending on the context.

Buy versus rent. Leasing equipment or using cloud tools turns CapEx into OpEx. That helps cash flow, but over many years it can cost more than owning. Run the numbers before you decide.

Five common mistakes

  1. Expensing everything to cut this year’s tax. If an item is capital, SARS can disallow the deduction.
  2. Capitalising everything and bloating the asset register with tiny items.
  3. Mixing repairs and upgrades on one invoice without splitting them.
  4. Forgetting to start depreciation once the asset is ready for use.
  5. Weak records for second-hand or related-party purchases.

A simple monthly routine

  1. Code every purchase as CapEx or OpEx when you capture it, not at year-end.
  2. Review anything above your threshold before it is paid.
  3. Keep one folder per asset with invoice, proof of payment and date brought into use.
  4. Reconcile your asset register to the balance sheet each quarter.
  5. Before year-end, ask your accountant what can still be planned. Our year-end tax planning guide lists the checks worth doing.

Our perspective

Most of the messy books we meet are not the result of fraud or carelessness. They come from a bookkeeper coding a bakkie deposit as “vehicle expenses” in month one, and nobody looking at it again. By the time the annual financial statements are due, the asset is missing, profit is understated and the tax return is built on a wrong foundation.

Our perspective — overview diagram

Our view is that classification should happen at the moment of capture, not at year-end. That is much easier when your accounting runs on cloud software with rules and approvals built in, rather than a spreadsheet someone updates when they remember. It also means that when SARS asks a question, the invoice, the asset record and the policy are already together.

We also think small businesses should stop treating the CapEx decision as a purely tax decision. Ask first whether the purchase makes the business stronger, then ask how it will be treated. The tax allowance is a bonus, not a reason to buy.

FAQ

What is CapEx and OpEx with an example?

CapEx is spending on something that lasts, such as a R250,000 delivery vehicle. OpEx is the cost of running the business, such as the fuel, insurance and driver’s salary that keep that vehicle on the road. The vehicle is written off over several years, while the running costs are expensed as they happen.

Are staff CapEx or OpEx?

Salaries and wages are OpEx. The exception is when employees work directly on building or preparing an asset. Then some of those costs can be capitalised, but only where they are directly attributable to getting the asset ready for use, as IAS 16 describes. Ask your accountant before capitalising payroll.

Is a laptop CapEx or OpEx?

It depends on your capitalisation policy. Many businesses expense cheaper laptops immediately and capitalise expensive ones. For tax, a laptop used for trade can qualify for a wear-and-tear allowance under section 11(e) if the requirements are met.

What are examples of OpEx?

Rent, salaries, electricity, internet, software subscriptions, marketing, insurance, fuel and routine repairs. They are consumed in running the business rather than building a lasting asset.

Is leasing equipment CapEx or OpEx?

It depends on the lease. Simple rentals are usually OpEx, but under accounting standards some leases must be recorded as assets and liabilities. Your accountant should review the contract before you decide how to book it.
