☕ Morning Coffee with SARS: Don’t Let Your Coffee Go Cold

☕ The Morning Brew

We’ve established that you’re a provisional taxpayer.

We’ve looked at what you’ve earned.

We’ve considered what the remainder of the tax year may bring.

And we’ve worked towards a reasonable estimate of your taxable income for the full year.

So, are we done?

Not quite.

Because provisional tax is more than calculating a number.

The estimate needs to be appropriate.

The IRP6 needs to be submitted.

And, where provisional tax is payable, the payment needs to be made.

For the 2027 first provisional tax period, all three deserve our attention.

 

☕ Today’s Blend: A Reasonable Estimate Has Rules

In Part 2, we spoke about the importance of estimating rather than guessing.

For the 2027 year of assessment, we are not simply looking at what you earned between March and August.

We are estimating your taxable income for the entire year of assessment – 1 March 2026 to 28 February 2027.

But there is another important part of that calculation:

The SARS basic amount.

Broadly, the basic amount is derived from the taxable income reflected in your latest relevant assessment, subject to certain statutory adjustments.

Where the estimate is made more than 18 months after the end of the latest preceding year of assessment, the basic amount is increased by 8% per year.

So can we simply estimate below the basic amount because we expect this year to be quieter?

Not without good reason.

A lower estimate may be appropriate where the circumstances support it, but the estimate must be reasonable and capable of being justified.

SARS may call upon a provisional taxpayer to justify an estimate and provide information relating to income and expenditure.

That brings us back to one of the most important principles in this series:

We are estimating. We are not guessing.

 

☕ From Estimate to Submission

Once we have arrived at an appropriate estimate of taxable income, we calculate the provisional tax attributable to the first period.

Broadly, the first provisional tax calculation starts with the estimated normal tax for the full year, takes the applicable rebates and tax credits into account, and then determines the amount attributable to the first six months.

Employees’ tax already deducted for the first six months and allowable foreign tax credits are then taken into account.

The result is the first provisional tax amount payable.

But preparing the calculation does not complete the process.

The estimate still needs to be submitted to SARS on the IRP6.

And where the calculation results in an amount payable, there is a further practical step:

The payment must actually be made to SARS.

Submitting the IRP6 and making the payment are related obligations, but they are not the same action.

Depending on the payment method used, the taxpayer may still need to authorise or release the payment through their banking platform.

This is why our provisional tax process doesn't stop when the IRP6 has been submitted.

We want our clients to know:

What has been declared.

What has been submitted.

What is payable.

And whether there is anything they still need to do.

 

☕ What If the Calculation Is Nil?

Sometimes, after completing the calculation, there may be no provisional tax payment due.

That does not mean the IRP6 can simply be ignored.

If you are required to submit an IRP6, the return must still be attended to even where the calculation results in R0 payable.

This distinction is important:

A nil payment and no filing obligation are not the same thing.

So before assuming that “nothing payable” means “nothing to do”, make sure you understand which one applies to you.

 

☕ Cash Flow and Tax Compliance Are Two Different Conversations

This is where provisional tax can become uncomfortable.

Sometimes the calculation is reasonable.

The taxpayer understands the estimate.

The resulting tax is correct.

But the cash simply isn't available.

Perhaps customers haven't paid.

Perhaps the business has significant funds tied up in stock.

Perhaps there has been an unexpected expense.

Or perhaps August has simply arrived at the wrong point in the cash-flow cycle.

These are genuine commercial realities.

But a cash-flow problem should not become a tax-disclosure problem.

Reducing an otherwise appropriate taxable income estimate simply because the resulting provisional tax payment is difficult to afford is not the answer.

The estimate should reflect the taxpayer's reasonable tax position.

The cash-flow problem should be dealt with separately.

We have said this before at Exponential Brilliance:

You may pay tax late – but you should not declare it incorrectly.

That does not mean paying late is without consequence.

Late provisional tax payments can attract penalties and interest.

The point is that two separate questions need to be answered:

What should I correctly declare to SARS?

and

How am I going to fund the resulting tax liability?

They are both important.

But they are not the same question.

 

☕ “Can’t We Just Fix It Later?”

Another question we often hear is:

“Can’t we pay less now and just make a top-up payment later?”

This is where we need to distinguish between the amount declared and the amount paid.

A later payment may settle or reduce tax that remains outstanding.

It does not necessarily correct the basis on which an earlier provisional tax estimate was made.

This distinction becomes particularly important when we reach the second provisional tax period, because that is when the accuracy of the final or last estimate becomes particularly relevant to SARS’s underestimation penalty rules.

So there is already a lesson worth remembering for February:

A later payment and an appropriate estimate are not the same thing.

 

☕ And What About the 80% and 90% Rules?

If you've dealt with provisional tax before, you've probably heard about:

The 80% rule.

The 90% rule.

The basic amount.

The 8% adjustment.

And the dreaded...

underestimation penalty.

All of these concepts matter.

But they don't all perform the same function.

The basic amount is already relevant when we consider the provisional tax estimate.

The familiar 80% and 90% tests, however, become particularly important when we reach the second provisional tax period and consider the potential consequences of underestimating taxable income.

So for our first provisional period, the focus should be clear:

Estimate appropriately.

Submit correctly.

Pay on time.

Keep the information supporting the estimate.

 

☕ A Little Something to Remember for February

We won't unpack the second provisional tax rules fully today – that's a conversation for another cup of coffee.

But it is worth understanding where we're heading.

For the second provisional tax period, where actual taxable income exceeds R1 million, the final or last estimate becomes particularly important in relation to the 80% test.

Where actual taxable income is R1 million or less, the relevant underestimation test considers 90% of actual taxable income together with the applicable basic amount, subject to the detailed rules.

This is precisely why provisional tax shouldn't be viewed as two isolated deadlines in August and February.

The estimate we make today is part of a process that we will revisit as the tax year develops.

By February, we know considerably more about what actually happened.

And our provisional tax position should reflect that.

 

☕ Provisional Tax Is More Than a Deadline

This is perhaps the most important message in this series.

Provisional tax is not merely about meeting a deadline.

Used properly, it gives us an opportunity to pause during the tax year and consider the bigger picture.

Where are we now?

What has changed?

What do we reasonably expect for the remainder of the year?

Is our estimate appropriate?

What tax is likely to become payable?

And importantly:

Have we planned the cash flow for it?

The conversation we're having in August shouldn't only be about August.

It should help us prepare for February – and ultimately for the final income tax assessment.

That is what proactive provisional tax planning looks like.

It isn't about predicting the future perfectly.

It isn't about manipulating an estimate to produce a preferred tax payment.

It's about using the information available today to make informed, supportable decisions about the tax position ahead.

 

☕ Your Provisional Tax Checklist

Before we close the first provisional tax period, make sure:

 ✔ Your expected taxable income for the full tax year has been considered.

✔ The applicable SARS basic amount has been considered.

✔ Material changes in your circumstances have been communicated to your tax practitioner.

✔ Your estimate is reasonable and supportable.

✔ The IRP6 has been submitted.

✔ You know whether there is an amount payable.

✔ If payment requires your authorisation, you have attended to it.

✔ Payment has actually been made by the applicable deadline.

✔ The IRP6, calculation and proof of payment have been retained.

✔ If cash flow is a concern, it has been discussed separately from the accuracy of the taxable income estimate.

Good provisional tax compliance is not one calculation.

It's a process.

 

☕ One Final Sip

In Part 1, we asked:

“Is your cup half full… or half taxed?”

In Part 2:

“How strong should we brew it?”

And now?

Don’t let your coffee go cold.

A good provisional tax process doesn't end when we've calculated a number.

It means arriving at an appropriate estimate, submitting the required return, dealing with the resulting payment and retaining the information supporting the position taken.

Because provisional tax is not merely about meeting a deadline.

It's about making the right decisions before the deadline arrives.

 

☕ Let’s Have Coffee

If your first provisional tax calculation has landed in your inbox, don't simply scroll to the amount at the bottom.

Understand the estimate.

Ask questions.

Tell your tax practitioner what has changed.

Know what has been submitted.

Know what needs to be paid.

And, importantly, understand what today's estimate means for the rest of your tax year.

A proactive conversation now can make February considerably easier.

So put the kettle on, pour yourself your favourite cup of coffee, and leave the tax brewing to us.

We're always happy to have coffee with you – even if it's only virtually.
