You do not sign up to be a provisional taxpayer
Provisional tax is not a status you apply for. SARS treats anyone who earns income other than a salary as a provisional taxpayer: freelance and consulting fees, side hustle income, rental income, or profit from running your own business. There is no registration or deregistration process. If your income fits the definition, you are one, and it is up to you to request and submit your IRP6 returns on eFiling.
The system exists because a salaried employee's tax is collected every month through PAYE, while nobody deducts tax from a freelancer's invoices. Provisional tax spreads that bill across the year instead of leaving you with one large, painful assessment after it ends.
Who is exempt, and why freelancers usually are not
There are two exemptions for individuals, and both only apply if you do not carry on a business:
- Your taxable income for the year is below the tax threshold (R99,000 if you are under 65, R153,250 if you are 65 to 74, R171,300 if you are 75 or older), or
- Your only income besides a salary is interest, foreign dividends, rental income or pay from an unregistered employer, and it comes to R30,000 or less for the year.
Freelancing, consulting and most side hustles count as carrying on a business, so neither exemption helps. A salaried employee who earns R15,000 a year doing weekend design work is a provisional taxpayer. A salaried employee whose only extra income is R12,000 a year in rent from a garden flat usually is not.
The dates that matter for the 2026/27 tax year
The tax year runs from 1 March 2026 to 28 February 2027. When a deadline falls on a weekend or public holiday, the payment is due on the last business day before it.
- First payment, 31 August 2026: half of your estimated tax for the full year. This one has already passed. If you missed it, submit and pay as soon as you can, because a 10% late payment penalty applies and interest keeps running until it is paid.
- Second payment, 26 February 2027: your full estimated tax for the year, less what you paid in August. 28 February 2027 is a Sunday, so the deadline moves to Friday the 26th.
- Third, voluntary top-up: due by the last business day of September after the tax year ends. It carries no penalty, and paying any shortfall here reduces the interest SARS charges on underpaid tax once your taxable income is above R50,000. For the tax year that ended on 28 February 2026, the top-up deadline is 30 September 2026.
Underestimating is the expensive mistake
Most freelancers worry about missing a deadline. The quieter risk is estimating too low on the second payment, because that is where the bigger penalty sits.
If your actual taxable income for the year is R1 million or less, your February estimate needs to be at least 90% of what you really earned, or at least your "basic amount", which is your taxable income from the latest year SARS has assessed. Fall short of both and SARS charges a penalty of 20% of the difference between the tax you should have estimated and the tax on the estimate you submitted. Above R1 million, the tolerance drops to 80% of actual taxable income and the basic amount no longer protects you.
Two other traps sit next to that one. If you skip the February IRP6 and still have not submitted it four months after the tax year ends, SARS treats it as an estimate of nil taxable income, which almost guarantees an underestimation penalty. And an accurate estimate paid late still attracts the 10% late payment penalty. The 2026 Budget also proposed tougher penalties for people who estimate correctly but pay late, so "at least my estimate was right" is becoming a weaker defence.
The safer approach is to base your estimate on what you have actually earned so far plus a realistic view of the remaining months, and to revise it upward in February if the year went better than expected.
How much to set aside from each invoice
The freelancers who stay calm at IRP6 time move a slice of every payment into a separate tax pot the day it lands, instead of treating their whole balance as spendable. The right slice depends on your income. Using the 2026/27 tax tables for someone under 65, after the R17,820 primary rebate, the tax on a taxable income of:
- R250,000 is about R27,600, roughly 11%
- R400,000 is about R67,400, roughly 17%
- R600,000 is about R132,900, roughly 22%
- R800,000 is about R208,000, roughly 26%
If freelancing is your only income, set aside a few percentage points above your expected average rate so there is a buffer. If it is a side hustle on top of a salary, use your marginal rate instead. Your salary has already used up the lower brackets and PAYE has already been paid on it, so every extra rand is taxed at your top rate. Someone with a R450,000 taxable salary pays 31% on each rand of side income, which means a 15% set-aside will fall well short.
It is the same principle behind a variable-income budgeting system: separate the money before you decide what it is for.
Your estimate is based on profit, not fees
Provisional tax is calculated on taxable income, which for a freelancer means fees minus legitimate business expenses. Software subscriptions, professional memberships, business travel and data costs reduce it, equipment can be written off over its useful life, and part of your home costs can count if a room is specifically equipped for your work and used regularly and exclusively for it. Log these as they happen instead of rebuilding them from bank statements in February, because every forgotten expense inflates both your estimate and your tax.

Quick answers
Do I still need to submit an annual tax return?
Yes. Provisional tax payments are advance payments toward your final bill, and the annual return reconciles them. For the tax year that ended on 28 February 2026, provisional taxpayers have until 22 January 2027 to file. SARS auto-assessed some provisional taxpayers this year: if you agree with yours, no further action is needed, and if you do not, you can correct it by the same date.
I have a full-time job. Does a small side hustle really count?
Yes. The R30,000 exemption does not cover business income, so even modest freelance or side hustle earnings make you a provisional taxpayer. The size of that income changes how much you pay, not whether the rules apply.
What if I earn less this year than last year?
Base your estimate on what you realistically expect to earn, even if it is below last year, and keep the records that explain the drop. SARS can ask you to justify an estimate that comes in lower than your last assessed taxable income.
Keeping the numbers ready between IRP6 dates
The hard part of provisional tax is rarely the calculation. It is knowing, in August and February, what came in and what went out. In Budget Hub you can record rental and other income separately from your salary, track spending across more than 30 expense categories, and import a CSV bank statement so you are not typing transactions in by hand. Then create a savings goal for your tax pot and move your set-aside into it after every invoice. Budget Hub tracks it with milestones like any other goal, so when the IRP6 is due you are checking a number you already have, not hoping one exists.
