Provisional Tax Assistance: IRP6 Filing Done Right
Last Updated: September 2026 | Reading Time: 7 minutes
Two IRP6 returns a year sounds simple until the underestimation penalty hits. Admin Boss – Tax division calculates, files and tracks your provisional tax so you never overpay SARS or hand them a penalty.
Quick Answer
Provisional tax is pay-as-you-go income tax for anyone earning income without full PAYE – freelancers, landlords, investors, commission earners and side-hustlers. You file IRP6 returns and pay by end August (first period) and end February (second period), with an optional third top-up in September. Under-estimate the second period by too much and SARS adds a 20% penalty.
Who Must Pay Provisional Tax
- Freelancers, consultants and independent contractors
- Anyone with rental income above R30,000/year
- Commission earners (see commission earner deductions)
- Directors of private companies and members of CCs
- People with significant interest, dividend or foreign income (above the exemptions)
The official rules are on the SARS provisional tax page; the deep mechanics are in our complete provisional tax guide.

The Underestimation Penalty Explained
The second-period estimate must be within the safe harbours: if your actual taxable income is R1 million or less, the estimate must be at least the lesser of the basic amount (last assessed year) or 90% of actual; above R1 million, at least 80% of actual. Miss it and SARS adds a 20% penalty on the shortfall – plus interest. This penalty catches thousands of freelancers every February.

Frequently Asked Questions
What is the difference between provisional tax and PAYE?
PAYE is tax your employer withholds from a salary monthly. Provisional tax is how you prepay tax on income where nobody withholds PAYE – freelance, rental, investment income – in two (optionally three) instalments per year. Both are credited against your final assessment.
What happens if I miss an IRP6 deadline?
SARS charges a 10% late-payment penalty on the amount due plus interest, and missing the February estimate entirely triggers the 20% underestimation penalty calculation. Catch up as fast as possible – penalties grow with time.
Can I pay provisional tax in monthly instalments instead?
No – the IRP6 system is fixed at two compulsory payments. But you may make voluntary advance payments through eFiling at any time to soften the August and February amounts.
