Most South African taxpayers deal with one of two tax collection systems: PAYE (Pay-As-You-Earn) or provisional tax. Many people are subject to both at the same time without realising it — and not knowing which system applies is one of the most common causes of unexpected SARS debt.
The short version: PAYE is how employed people pay tax — your employer deducts it monthly and pays it to SARS on your behalf. Provisional tax is how everyone else pays — self-employed people, freelancers, landlords, business owners, and salaried employees who also earn significant non-salary income. You pay in advance, in instalments, based on an estimate of your annual taxable income.
This guide explains exactly which system applies to your situation, when the thresholds that trigger provisional tax registration kick in, and how each system works in practice.

Key Takeaways
- If all your income is a salary with PAYE deducted, you are generally not a provisional taxpayer and do not need to file IRP6 returns — only an ITR12 after the tax year.
- If your non-PAYE income (freelance, rental, interest, dividends) exceeds R30 000 per year AND your total taxable income exceeds the annual threshold (R95 750 for under-65s in 2025/26), you must register as a provisional taxpayer.
- Provisional taxpayers make two compulsory payments: first period by 31 August, second period by the last day of February — plus an optional top-up by 30 September.
What Is PAYE and How Does It Work?
PAYE (Pay-As-You-Earn) is a withholding system where your employer calculates the income tax due on your salary each month, deducts it from your pay, and remits it directly to SARS on your behalf. You do not handle the payment — your employer does.
At the end of the tax year (28/29 February), your employer issues an IRP5 certificate showing total remuneration and total PAYE paid. You include this in your ITR12 tax return. If PAYE was calculated correctly throughout the year, your assessment should show a small refund or small additional liability — not a large one.
PAYE covers:
- Salary, wages, and overtime
- Bonuses and performance payments
- Allowances (travel, subsistence) — partially, depending on structure
- Benefits in kind (company car, medical aid contributions)
PAYE does not cover income that does not flow through your employer: freelance fees paid directly to you, rental income from a property you own, interest above the annual exemption, dividends from investments held personally, or business income from a side venture.
Citation capsule: PAYE (Pay-As-You-Earn) is the withholding tax system under which South African employers deduct income tax from employee remuneration monthly and remit it directly to SARS. Employees whose entire taxable income consists of PAYE-taxed salary generally do not need to register as provisional taxpayers. Additional income outside the PAYE system triggers provisional tax registration obligations when it exceeds the R30 000 threshold (SARS, “Guide to Provisional Tax”; TaxTim SA, “Provisional Tax” guide).

What Is Provisional Tax and Who Must Register?
Provisional tax is not a separate tax — it is a payment mechanism that allows SARS to collect income tax during the year on income that is not subject to PAYE. The tax you eventually pay is the same rate; you just pay it in advance instalments based on your own estimate, rather than having an employer calculate and remit it monthly.
You must register as a provisional taxpayer if you:
-
Carry on any trade — this includes freelancing, consulting, running a business, operating a side hustle, or any self-employment activity, regardless of the amount earned
-
Earn non-PAYE income above R30 000 — if you receive rental income, interest income, dividend income, or any other taxable income not subject to PAYE, and the total of that income exceeds R30 000 in the tax year, AND your total taxable income exceeds the annual tax threshold (R95 750 for under-65s in 2025/26)
-
Are a company, close corporation, or trust — all juristic persons are provisional taxpayers by default
You are generally NOT a provisional taxpayer if:
- All your income is from a single employer with PAYE correctly deducted, and you earn nothing else
- You are a pensioner (over 65) whose income is entirely from a pension/annuity with PAYE deducted, interest below the R34 500 exemption, and dividends (withholding tax applies)
- Your total taxable income is below the annual tax threshold (under the tax-free amount)
The R30 000 threshold in practice:
| Your situation | Must register as provisional taxpayer? |
|---|---|
| Salary only, PAYE deducted | No |
| Salary + R20 000 interest income | No (R20 000 < R30 000 threshold) |
| Salary + R35 000 rental income | Yes (R35 000 > R30 000 threshold) |
| Salary + R5 000 freelance income | Yes (any trade activity triggers registration) |
| Freelancer with no salary | Yes (always) |
| Pensioner with interest under R34 500 | No |
| Pensioner with interest over R34 500 | Yes (if total taxable income exceeds threshold) |
Can You Be Both a PAYE Taxpayer AND a Provisional Taxpayer?
Yes — and this is extremely common. A salaried employee who also earns rental income above R30 000, or who does any freelance work on the side, is both:
- A PAYE taxpayer through their employer (monthly deductions from salary)
- A provisional taxpayer for the additional non-PAYE income
In this situation, your provisional tax payments cover the tax liability on your non-salary income. Your IRP6 submissions estimate your total annual income — salary plus other income — but the PAYE already paid is credited against your total liability, so you only top up the difference.
Failing to register as a provisional taxpayer because you have a salary and think “PAYE covers everything” is a frequent compliance mistake. SARS does not automatically credit your employer’s PAYE payments against a provisional tax obligation you have not registered for — the two systems must be linked through your ITR12.
Provisional Tax Payment Deadlines
Provisional taxpayers make two compulsory payments per tax year, plus one optional payment:
First period (P1) — due 31 August: You submit an IRP6 return estimating your taxable income for the full year. You pay 50% of the estimated annual tax liability as a first instalment. The estimate must be at least 90% of your eventual actual liability to avoid underestimation penalties.
Second period (P2) — due last day of February: You submit a second IRP6 with a revised estimate for the full year. You pay the balance of estimated tax not yet paid (total estimated tax minus P1 payment). By February, your income for the full year is largely known, so the estimate should be accurate.
Optional third payment — due 30 September: After the tax year ends (on 28 February), you have until 30 September to make a voluntary top-up payment if your actual income turns out higher than your P2 estimate. Paying before 30 September eliminates interest that would otherwise accrue on any underpayment.
2026 provisional tax deadlines:
| Payment | Deadline | Description |
|---|---|---|
| First period (P1) | 31 August 2026 | 50% of estimated annual tax |
| Second period (P2) | 28 February 2027 | Balance of estimated annual tax |
| Optional top-up | 30 September 2027 | After-year-end adjustment to avoid interest |
Citation capsule: South African provisional taxpayers make two compulsory IRP6 submissions and payments per tax year: the first period (P1) by 31 August, covering 50% of estimated annual tax, and the second period (P2) by the last day of February, covering the balance. An optional third top-up payment by 30 September allows taxpayers to correct underestimates before interest accrues. All submissions are via SARS eFiling (SARS, “Guide to Provisional Tax”; Joburg ETC, “Provisional tax warning issued for South Africans ahead of 2026 deadline”).

How to Calculate Your Provisional Tax Payment
The IRP6 requires you to estimate your total taxable income for the year. This estimate drives both the P1 and P2 payments.
Basic calculation:
- Estimate your total taxable income for the year (salary + freelance income + rental income + other)
- Calculate the income tax on that amount using the current year’s tax tables and rebates
- Subtract any PAYE already paid through your employer (shown on your latest payslip annualised)
- Divide the remainder: 50% due at P1, the balance due at P2
Example — salaried employee with rental income:
| Item | Amount |
|---|---|
| Gross salary (PAYE deducted at source) | R480 000 |
| Net rental income (after deductible expenses) | R72 000 |
| Total estimated taxable income | R552 000 |
| Income tax on R552 000 | ~R147 138 |
| Less: rebate (under 65, 2025/26) | (R17 235) |
| Net income tax payable | ~R129 903 |
| Less: PAYE already deducted by employer | ~R93 000 |
| Provisional tax balance | ~R36 903 |
| P1 payment (50% of balance) | ~R18 452 |
| P2 payment (remaining balance) | ~R18 451 |
Note: These figures are illustrative. Actual tax rates and rebates must be taken from the current SARS tax tables for the relevant year.
The 90% Rule and Underestimation Penalties
If your actual taxable income for the year turns out to be significantly higher than what you estimated in your IRP6 submissions, SARS imposes an underestimation penalty on the shortfall.
The 90% rule: Your estimate must be at least 90% of your actual taxable income. If you estimated R400 000 and your actual was R500 000, your estimate was 80% of actual — the 10-percentage-point shortfall triggers a 20% penalty on the underestimated tax.
The basic amount rule: For taxpayers whose taxable income is below R1 million, SARS allows you to base your IRP6 estimate on your previous year’s assessed taxable income (the “basic amount”) — increased by 8%. If your actual income is higher, you are not penalised as long as your estimate met the basic amount threshold. This simplifies provisional tax for freelancers and small business owners with relatively stable income.
Avoiding penalties:
- Base P1 on the basic amount (last year’s assessment + 8%) if your income is relatively stable
- At P2, refine your estimate using actual year-to-date income — accuracy here is critical
- If your income is unexpectedly high, make the optional top-up payment by 30 September
How to Register as a Provisional Taxpayer
If you have non-PAYE income above the R30 000 threshold and are not yet registered as a provisional taxpayer, register immediately — penalties apply from the date you should have been registered, not from the date SARS discovers the omission.
Steps to register on eFiling:
- Log into SARS eFiling at sarsefiling.co.za
- Go to Home → Maintain SARS Registered Details → Maintain Tax Type
- Select “Provisional Tax” and tick the registration checkbox
- Submit — activation is typically immediate for individuals already registered for income tax
- Your profile will now show a provisional tax obligation, and IRP6 forms will appear for upcoming deadlines
Alternatively, call the SARS Contact Centre at 0800 00 7277 and request provisional tax registration with your tax reference number ready.

Frequently Asked Questions
I’m a freelancer who earned only R45 000 this year — do I need to register for provisional tax?
Yes. Any person who carries on a trade — including freelancing, consulting, or any self-employment activity — must register as a provisional taxpayer, regardless of the amount earned. The R30 000 threshold applies only to non-trade passive income (interest, rental, dividends) for otherwise PAYE-only employees. A freelancer’s trade income has no minimum threshold for registration.
What happens if I miss a provisional tax deadline?
Missing the P1 or P2 deadline triggers an automatic late payment penalty of 10% of the tax due, plus interest at the prime overdraft rate from the due date. SARS does not routinely grant extensions for provisional tax deadlines. If you cannot pay in full, contact SARS before the deadline to request a payment arrangement — arrangements in good standing prevent the non-payment from compounding further.
How do I avoid a large bill at assessment if I am a provisional taxpayer?
The most common cause of large assessment bills is underestimating provisional tax during the year. Use the P2 opportunity (due in February) to refine your estimate using your actual year-to-date income. If you have had a better-than-expected year, increase your P2 payment accordingly. Making the optional top-up payment by 30 September after year-end eliminates interest on any remaining balance.
I have a full-time job and started freelancing on the side. What do I need to do?
Register for provisional tax on eFiling immediately. At your next P1 deadline (31 August), submit an IRP6 estimating your total income — salary plus freelance income — and pay 50% of the tax on that combined amount, minus PAYE already paid by your employer. Your ITR12 at year-end will reconcile everything. The key is not to assume that your employer’s PAYE covers the freelance income — it does not.
Can I submit my own IRP6, or do I need an accountant?
Most individuals with straightforward income can submit IRP6 returns themselves on eFiling. The form requires your estimated taxable income, which you calculate as described above, and eFiling applies the tax tables and rebates automatically. An accountant adds value if your income is from multiple complex sources, you have business expenses to calculate, or your income varies significantly year to year and accurate estimation is important.
The distinction between PAYE and provisional tax is not complicated once the logic is clear: PAYE is collected by your employer on salary; provisional tax is self-managed for everything else. The risk is not in understanding the system — it is in assuming PAYE alone covers all your income when it does not. If you have any non-salary income, check the thresholds, register if required, and submit on time.
