Provisional tax for freelancers in South Africa: dates and how to prepare

If you earn income that is not taxed through a single employer's payroll, SARS expects you to pay tax in advance, twice a year, through the provisional tax system. Most freelancers, sole proprietors, consultants, and side-hustlers in South Africa are provisional taxpayers without realising it until a penalty arrives.

This guide covers who has to pay, the deadlines, how the payments are calculated, and the simple record-keeping habit that turns provisional tax from a scramble into a 20-minute job.

Who has to pay provisional tax?

You are a provisional taxpayer if you earn income that does not have PAYE deducted at source. That typically includes:

• Freelance and consulting income
• Sole proprietor or small business profit
• Rental income
• Investment income above the exemption thresholds
• Any meaningful income earned alongside a salaried job

If you only earn a salary and your employer deducts PAYE, you are generally not a provisional taxpayer. The moment you add freelance or business income on the side, you usually become one.

The provisional tax deadlines

Provisional tax is filed on an IRP6 return. There are two compulsory payments and an optional third.

• First period: due by 31 August (six months into the tax year). You estimate your taxable income for the full year and pay tax on half of it.
• Second period: due by the last day of February (the end of the tax year). You re-estimate the full-year income and settle the balance for the year.
• Third "top-up" period (voluntary): by 30 September after the tax year ends. This lets you top up if your estimate fell short, before interest builds up.

How the payments are worked out

Each provisional payment is based on your estimated taxable income, which is your income minus your deductible expenses. That is the important part for freelancers: the more of your legitimate expenses you have captured, the lower your taxable income, and the less provisional tax you pay.

A rough flow:

1. Estimate your total income for the tax year.
2. Subtract your deductible business expenses (the receipts you have kept).
3. Apply the income tax tables to get the estimated tax for the year.
4. For the first period, pay tax on half. For the second, settle the full-year liability less what you already paid.

If you under-estimate your income by too much on the second period, SARS can levy an under-estimation penalty. If you over-estimate, you have simply pre-paid and get it back on assessment. The goal is a realistic estimate, which depends entirely on knowing your real expenses.

Why record-keeping decides your provisional tax bill

Here is the trap. Provisional tax is due in August, when the tax-year deadlines feel far away. Most freelancers estimate their income off the top of their head, forget half their deductible expenses, and over-pay. Or they under-estimate and get penalised.

Both problems come from the same root: not having the expenses captured and totalled when the deadline arrives.

If every receipt is already photographed and categorised, the August and February estimates take minutes. You pull your total spend by category, subtract it from your income, and you have a defensible number. For the categories that carry most of the deduction weight, see tax-deductible expenses for SA freelancers.

The simple habit that fixes it

1. Capture each slip when you get it. Do not wait for the deadline.
2. Keep the 15% VAT and the category on every slip, so your numbers are ready.
3. Pull a summary before each provisional deadline to estimate income minus expenses.
4. Keep the originals for five years in case SARS asks (see how long to keep records).

Snap-a-Slip is built around this habit. You photograph receipts on WhatsApp through the year, it categorises them and tracks the spend, and when 31 August comes around you export a clean total instead of digging through a shoebox. Less guesswork, lower estimates, no penalties for sloppy maths.

The bottom line

If you earn income outside a salary, you are almost certainly a provisional taxpayer, with payments due by 31 August and the last day of February. The size of each payment depends on your estimated income minus expenses, so the freelancers who keep their receipts through the year pay the least and file the fastest. Capture as you go, and provisional tax stops being stressful.

Start on WhatsApp and have your expenses ready before the next deadline.
