Key Components of South African Taxation

South Africa's taxation system is multifaceted, encompassing various types of taxes.

Here's an overview of the key tax types:

Personal Income Tax: Levied on the income of individuals. Residents in South Africa are taxed on their worldwide income, while non-residents are taxed only on income sourced within the country. This includes income from employment, business, and investment.
Corporate Income Tax: Imposed on companies operating in South Africa. This tax is applicable to both domestic companies on their worldwide income and foreign companies on their South African-sourced income.
Value-Added Tax (VAT): A consumption tax placed on a product whenever value is added at each stage of the supply chain, from production to the point of sale. Businesses must register for VAT if their annual turnover exceeds a certain threshold.
Capital Gains Tax (CGT): Levied on the sale of certain assets when a capital gain is realized. This applies to both individuals and companies and includes assets such as real estate, stocks, and bonds.
Dividend Tax: A tax on shareholders when dividends are paid to them. It is withheld at the source by the company distributing the dividends.
Property Taxes: Local taxes levied by municipalities on real estate. The amount varies depending on the municipality and the value of the property.
Estate Duty: A tax on the estate of a deceased person. It is levied on the value of the estate exceeding a certain threshold.
Transfer Duty: A tax levied on the transfer of property. It is calculated based on the value of the property being transferred.

Our Old Mutual tax calculator focuses primarily on personal income tax, helping individuals estimate their tax liability based on their annual income and deductions.

Provisional Tax Explained in 5 Minutes | Natasha Lorde

Understanding Provisional Tax in South Africa

Provisional tax is the South African Revenue Service’s (SARS) way of ensuring that individuals who don't earn a regular salary (and therefore aren't paying PAYE monthly) still pay their tax throughout the year. Instead of waiting until the end of the year to be hit with a big tax payment, you estimate your annual income and pay tax in two parts through the course of the tax year.

You're a provisional taxpayer if you earn income not already taxed before it’s paid out to you. That includes freelancers, side hustlers, consultants, Airbnb hosts, Uber drivers, and anyone earning rental or investment income.

💡Provisional Tax is a system where individuals who don't earn a fixed salary pay their tax in advance, based on their estimated income.

Do I have to pay provisional tax?

The short answer: if you earn more than R30,000 income a year from sources that don’t deduct PAYE, and more than R95,750 a year in total income, you likely need to register as a provisional taxpayer.

Examples:

You're a freelancer billing clients directly.
You drive Uber on weekends.
You have a full-time job but earn over R30,000 from freelance gigs.
You rent out a room on Airbnb.

If any of these sound like you, it's time to check your status on SARS eFiling.

When and How is Provisional Tax Paid?

Within one tax year timeline, you have to keep note of the following dates (in chronological order):

First provisional payment: 31 August
Second provisional payment: 28 February
Third top-up payment (optional): 30 September the next year - this is only if your earlier estimates were too low and you want to “top up” your payments.
Finalising your tax return for the tax year: You then have from 21 July until 19 January (or thereabouts - the exact dates change every year) of the next year to finalise and submit your final tax return.

We know this can be the most confusing bit - so we put together a timeline to show you how the payments are structured: Your 2026 Provisional Tax Deadlines

You submit an IRP6 form for each payment via SARS eFiling.

💡An IRP6 is a SARS tax return form used by provisional taxpayers to declare their estimated income and make payment.

The basic formula to calculate your tax is estimated taxable income × your effective tax rate.

Tip: Be realistic in your estimates. Underestimating how much you will earn can mean you pay penalties (more on that later).

Tax-deductible expenses for freelancers, sole proprietors, and side hustlers

If you’re a freelancer or have a side hustle, you can claim certain expenses against your income to lower your taxable amount. Some common SARS-accepted deductions include:

Office/studio rent (or a portion of your home if you work from home)
Internet and cellphone bills
Business-related transport and travel costs
Advertising and marketing
Software and subscriptions (like Canva, Adobe, Xero)
Business equipment (laptops, printers, cameras, tools, desks)
Bank charges and transaction fees
Professional services (accountants, legal advice)
Training courses or certifications related to your work
Business insurance

In order to deduct these expenses, you need to keep a thorough log of these expenses and store your receipts for bigger expenses (should you find yourself being audited by SARS).

💡Franc Hustle was built to help with exactly this. If you subscribe to a Franc Hustle account, you can connect your bank accounts (or upload bank statements) to the app to keep a log of all your expenses, tag them with SARS-friendly labels as you track them.

How to prepare for provisional tax return dates:

Keep a clear record of your income and expenses.
When you’re recording your expenses, use SARS-friendly tags to categorise (you’ll find these under the Expenditure section of your tax assessment documents).
Save for your tax monthly.
Save at least 25% of your income in a separate high-interest savings pot or money market fund you can easily access, so you don’t get hit with a big, unexpected cost at tax payment time.
Keep receipts for big business expenses. SARS might ask you for proof of these expenses at tax return time.
Schedule tax return and payment dates in your calendar. Make sure to set a reminder at least a week before so that you have enough time to get your information in place.

💡Says Lyndall: “I use the Franc Savings Pot (which is invested 100% in a money market fund) to save for my provisional tax payment. On a monthly basis I put away 25% of consulting income in this goal, then in the provisional tax payment months I withdraw my tax savings and pay it over to SARS. For my last provisional payment (Aug 2025) I was happy to find my tax savings had increased by R3,200 due to interest income earned. Free money!”

How to register and submit an IRP6 return

To register:

Log in to your SARS eFiling profile.
Go to ‘Home’ via the top menu.
Select ‘User’ on the left menu, then select ‘Tax Types’
Update your 'Tax Types' by ticking the 'Provisional Tax (IRP6)' box.

To submit an IRP6 form:

Navigate to Returns > Returns Issued > Provisional Tax (IRP6)
Select the correct tax period from the ‘Select Period’ drop-down list and ‘Request Return’
Select ‘IRP6’ under ‘Return Type’
Fill in your estimated income and calculate tax
Submit by clicking on ‘File Return’ and make payment

Provisional tax penalties (and how to avoid them)

SARS can charge you a penalty if your returns or payments are late, or if you underestimate your income. Here are the penalties to avoid:

You pay a penalty if your payment is late. A 10% penalty on the total tax amount will be applied if your payment is even a few days late. If the deadline falls on the weekend or a public holiday, be sure to submit on the weekday before then. There’s also a 10% per year interest charge on late payments.
You pay a penalty if you underestimate your taxable income.

The penalty applied depends on whether your taxable income amounts to more or less than R1 million.

If you earn R1 million or less in the year, an under-estimation penalty applies if your second provisional return is less than 90% of your actual taxable income for the year (i.e. you’re 10% off in your estimation) and is less than your ‘basic’ amount (your taxable income on your most recent assessment). In this case, your penalty will be 20% of the difference between the tax you would pay on your estimated amount, and the tax on 90% of your actual taxable income, or your ‘basic’ amount (whichever is less).
If you earn more than R1 million in the year, an under-estimation penalty applies if your second provisional return is less than 80% of your actual taxable income for the year (i.e. you’re 20% off in your estimation). Your penalty will be 20% of the difference between the tax you would pay on your estimated amount, and the tax on 80% of your actual taxable income.
You pay a penalty if you don’t submit your returns by the deadline. If you file your provisional tax return late, SARS sees this as you filing a return on R0 taxable income. That means a 20% under-estimation penalty will be applied.

Provisional tax doesn’t have to be painful. With the right info and the right tools, it’s totally doable on your own.

The Franc Hustle Account was built for self-employed South Africans who want to stay on top of their money and make tax time easier.

South African Tax Brackets and Rates

R226,001 - R353,100	R40,680 + 26% of taxable income above R226,000
R353,101 - R488,700	R73,726 + 31% of taxable income above R353,100
R488,701 - R641,400	R115,762 + 36% of taxable income above R488,700
