Provisional Tax Explained: A Plain-English Guide for South African Freelancers (2026)

If you’re a freelancer in South Africa and you’ve just discovered that “provisional tax” is a thing — and that you might be late paying it — welcome to the club. The SARS system was designed for the salaried, the corporate, and the patient. Not for the freelancer trying to figure out whether they owe money in February or August or both.

This guide explains provisional tax in plain English. No jargon, no assumed knowledge, no R800 phone call to an accountant.

What is provisional tax, actually?

Provisional tax is just a way SARS makes you pay your income tax in advance, in two instalments during the year, rather than waiting until you file your annual return.

If you’re employed, your boss does this for you every month via PAYE (Pay As You Earn) — your tax is taken off your salary before it hits your account.

But if you’re a freelancer, sole proprietor, or have significant non-salary income, nobody is doing that for you. So SARS makes you estimate your income, work out the tax, and pay it twice a year. That’s provisional tax.

It’s not a separate tax. It’s the same income tax you’d owe anyway — you’re just paying it in two upfront chunks instead of one lump sum at the end of the tax year.

Who needs to pay provisional tax?

You’re a provisional taxpayer if any of the following apply:

• You earn income that doesn’t have PAYE deducted from it (freelance, consulting, rental, dividends above the threshold, side hustle income)
• You’re a sole proprietor running your own business
• You’re a director of a private company (in many cases)
• Your non-salary income exceeds R30,000 per tax year and you’re under 65 (the threshold is R50,000 if you’re 65 or older)

You’re NOT a provisional taxpayer if:

• All your income is from a salary with PAYE deducted
• Your additional non-salary income is under R30,000 (or R50,000 if 65+)
• Your interest, dividends, and rental income (combined) is below R30,000 per year

The two payment dates you can’t miss

Provisional tax has two compulsory payments per year, with an optional third “top-up” payment:

First provisional payment: 31 August

Six months into the tax year (which runs March to February). You estimate your full-year taxable income and pay tax on half of it.

Second provisional payment: 28 February

The last day of the tax year. You re-estimate your full-year income (now with much better information), calculate your total tax owed, subtract what you paid in August, and pay the rest.

Optional third payment: 30 September (the next year)

If your first two estimates were too low, you can make a third “top-up” payment in September to avoid interest charges. This is voluntary but smart if you under-paid.

Practical tip: SARS doesn’t send you reminders for these dates. Mark them in your calendar yourself, or use a tool that does (more on that later).

How is provisional tax calculated?

Here’s where most people get confused. Provisional tax uses your estimated taxable income — not your actual income, because the year isn’t over yet.

The formula in plain English:

1. Estimate your total taxable income for the whole tax year
2. Calculate the tax on that estimated income using SARS’s normal tax tables
3. Subtract any rebates and medical credits you’re entitled to
4. The result is your total estimated tax for the year
5. For the first payment, you pay half of that
6. For the second payment, you pay the rest (less what you paid in August)

A worked example: Sipho the freelance copywriter

Let’s make it real. Sipho is 32, freelances full-time, and expects to earn R600,000 in the 2026/27 tax year.

His estimated taxable income

After deducting business expenses (laptop, internet, home office, professional subscriptions), he estimates his taxable income at R510,000.

His estimated tax

Using the 2026/27 tax brackets:

• First R237,100: 18% = R42,678
• R237,101 to R370,500: 26% = R34,684
• R370,501 to R510,000: 31% = R43,254
• Total: R120,616

Minus the primary rebate (R17,235 for under-65s) = R103,381

His provisional payments

• 31 August 2026 (first payment): R103,381 ÷ 2 = R51,690
• 28 February 2027 (second payment): Re-estimate based on actual income to date, then pay the remainder

If by February Sipho’s actual full-year tax works out to R110,000, his second payment would be R110,000 − R51,690 = R58,310.

The “underestimation” penalty trap

This is where freelancers get burned. SARS doesn’t just want you to pay on time — they want your estimate to be accurate.

If your second provisional estimate is less than 80% of your actual final tax liability, SARS charges an underestimation penalty of 20% on the shortfall.

Example: You estimated your taxable income as R400,000 but it ended up being R600,000. Your tax owed was much higher than you estimated. SARS will hit you with a 20% penalty on the difference.

How to avoid this:

• Track your income monthly (a simple spreadsheet works, or a tool that does it for you)
• Re-estimate at the end of January with the most current information
• When in doubt, overestimate slightly. Overpaying just means a refund — underpaying means penalties.

What if I just don’t pay?

Don’t do this.

• Late payment penalty: 10% of the amount owed
• Interest: charged at SARS’s prescribed rate (currently around 11.75% per year)
• Repeated non-compliance: SARS can audit you, garnish your accounts, or refer the matter for criminal prosecution in extreme cases

Provisional tax non-compliance is one of the most common reasons freelancers end up in trouble with SARS. The system assumes you’ll comply — and when you don’t, the penalties stack up fast.

How do I actually pay it?

The mechanics:

1. Log in to SARS eFiling (efiling.sars.gov.za)
2. Find the IRP6 form for the relevant period (first or second payment)
3. Enter your estimated taxable income
4. eFiling calculates the tax owed
5. Submit the form (this creates the obligation on your SARS account)
6. Pay via EFT using the payment reference SARS gives you, eFiling credit push, or debit card

The IRP6 form is short — maybe 10 fields. But the thinking behind those fields (how do I estimate accurately?) is where freelancers get stuck.

Common provisional tax mistakes freelancers make

After watching hundreds of SA freelancers navigate this, the same mistakes come up:

1. Forgetting to register as a provisional taxpayer. It’s a separate step from registering for income tax. You need to opt in.
2. Estimating based on last year’s numbers when your business has grown significantly. You’ll under-pay and get penalised.
3. Not deducting business expenses when calculating taxable income. You’re paying tax on revenue, not profit — that’s wrong.
4. Forgetting the second payment because you only remembered the first.
5. Treating it as optional. It isn’t. The penalties are real.
6. Not keeping receipts. When SARS audits (and they sometimes do), you’ll need to prove every deduction.

Should you DIY or get help?

Honest answer: it depends.

You can probably DIY if:

• Your income is consistent and predictable
• You have decent record-keeping habits
• You’re comfortable with basic math and eFiling

You probably want help if:

• Your income varies wildly month to month
• You have multiple income streams (freelance + rental + investments)
• You have significant deductions you’re unsure about
• You’ve already missed a payment and are dealing with penalties

For most freelancers, a mid-ground works best: do the work yourself with good tooling that handles the calculations, deadlines, and record-keeping for you. An accountant charges R3,000–R8,000 for provisional tax assistance. Tools cost a fraction of that.

The bottom line

Provisional tax isn’t optional. The deadlines are 31 August and 28 February. The penalties for missing or under-estimating are real. But the process itself isn’t complicated once someone explains it without jargon.

If you’ve been winging it, here’s what to do this week:

1. Check whether you’re registered as a provisional taxpayer (eFiling → Taxpayer profile)
2. Pull together your year-to-date income and expenses
3. Calculate (or get help calculating) your estimated full-year tax
4. Note the next deadline in your calendar
5. Make sure you have a system for tracking income and expenses through the year
