PAYE and provisional tax are the same tax, collected differently
This is the part that trips people up first: PAYE and provisional tax are not two different taxes. There is one South African income tax system, with one set of brackets and one primary rebate, defined in the Income Tax Act. What differs is how that tax reaches SARS.
With PAYE (Pay-As-You-Earn), your employer does the work. They calculate your liability based on your salary, deduct it every month, and pay it over to SARS under the Fourth Schedule to the Income Tax Act. You never touch the money or the paperwork. Our how PAYE works guide breaks down that monthly calculation step by step.
With provisional tax, there's no employer in the middle. You estimate your own annual income, work out the tax on it using the same brackets, and pay SARS directly, in two main instalments during the tax year, with an optional third top-up payment afterwards. It exists because SARS can't collect tax automatically from income that doesn't run through a payroll.
Side-by-side comparison
| PAYE | Provisional Tax | |
|---|---|---|
| Who calculates it | Your employer | You, or your accountant |
| Who pays SARS | Your employer, monthly | You, directly, twice a year |
| Typical taxpayer | Salaried employee | Freelancer, business owner, landlord |
| Payment frequency | 12 times a year | 2 main payments (plus an optional 3rd) |
| Tax brackets used | Same annual brackets | Same annual brackets |
| Registration needed | Automatic via employer | Must actively register with SARS |
| Risk of underpaying | Low, employer handles it | Higher, based on your own estimate |
How PAYE works, briefly
Every month, your employer annualises your salary, runs it through the tax brackets, subtracts your age-based rebate, and divides the result by 12. That figure comes off your payslip before you ever see the money. If you want the full four-step breakdown with a worked example, see our dedicated PAYE guide, or run your own numbers through the PAYE calculator.
How provisional tax works, briefly
If you're a provisional taxpayer, you submit an estimate of your total taxable income for the year to SARS twice: the first estimate around the end of August (six months into the tax year), and a final, more accurate estimate around the end of February (tax year-end). Each submission comes with a payment covering roughly half your estimated annual liability. If your final assessed tax turns out higher than what you paid, a third "top-up" payment can follow later in the year to avoid interest charges. A dedicated beginner's guide to provisional tax registration and deadlines is coming soon; in the meantime, the provisional tax calculator estimates both payments for you.
Who actually has to pay provisional tax?
You're generally required to register as a provisional taxpayer if you earn income that isn't taxed through an employer's payroll. In practice, this covers:
- Freelancers and independent contractors invoicing clients directly
- Sole proprietors and small business owners
- Company directors who receive income other than a standard PAYE salary
- Landlords earning meaningful rental income
- Anyone with significant investment or other non-salary income above the tax threshold
Purely salaried employees with no other income sources usually never need to register; PAYE already covers them in full.
Provisional Tax Payer or Non Provisional Tax Payer?
So what is a provisional tax payer in plain terms? It is anyone SARS expects to pay tax on income that does not already go through PAYE. A SARS provisional tax payer usually files two estimates a year instead of waiting for one annual assessment. Most salaried workers are non provisional tax payers because their employer already handles everything through payroll. You only move into the provisional group once you start earning meaningful freelance rental or business income alongside or instead of a salary.
Can you pay both at once?
Yes, and it's more common than people expect. Say you're employed full-time and earning a salary (PAYE applies), but you also freelance on weekends or rent out a second property (provisional tax applies to that portion). SARS expects you to declare both income streams on your annual return. The PAYE already deducted by your employer counts as a credit against your total tax bill, so provisional tax on the side income is calculated on top of, not in addition to, what's already been paid through your payroll.
Why this distinction matters for salary structuring
Understanding which system applies to which income stream matters most when you're weighing up how to structure your earnings, for example deciding between a full-time salaried role, a contractor arrangement, or a mix of both. Contracting often looks like higher gross pay, but shifts the entire tax administration burden, and the cash-flow discipline of setting aside money for provisional payments, onto you. A dedicated salary structuring and tax efficiency guide covering this trade-off is coming soon to this site.

Frequently asked questions
What is the main difference between PAYE and provisional tax?
PAYE is income tax deducted monthly by an employer from a salary, on behalf of SARS. Provisional tax is the same income tax, but paid directly to SARS by the taxpayer, usually twice a year, and applies to people earning income that isn't already taxed through an employer's payroll.
Can I pay both PAYE and provisional tax in the same year?
Yes. A salaried employee with a side income, such as freelance work, rental income, or a small business, pays PAYE on their salary and registers for provisional tax on the additional income. SARS treats these as separate obligations that both feed into the same annual tax return.
Who must register as a provisional taxpayer in South Africa?
Anyone who earns income not subject to PAYE, such as freelancers, sole proprietors, independent contractors, company directors receiving non-PAYE income, and individuals with significant rental or investment income above the threshold, is generally required to register as a provisional taxpayer with SARS.
Is provisional tax an extra tax on top of normal income tax?
No. Provisional tax is not a separate or additional tax. It uses the exact same tax brackets and rebates as PAYE. It is simply a different collection method: paying estimated tax in advance instead of having it deducted automatically from a payslip.
