How to Use the SARS Penalty Calculator 2026 - Complete SA Guide

SARS penalties accumulate quickly. A missed submission, a late VAT payment, or an understatement on your return can attract penalties of 10-200% on top of the original tax owed — plus interest compounding monthly. The SARS Penalty Calculator helps you estimate what you owe before you contact SARS, so you can budget for the settlement and decide whether to apply for a remission.

Why SARS Penalties Matter More Than You Think

Most taxpayers assume that penalties are a small add-on. In reality:

• A late payment penalty of 10% on R50,000 outstanding VAT is R5,000 — added on day one
• Interest at the SARS prescribed rate (currently prime + approximately 5.5%) accrues monthly on both the original amount and the penalty
• Understatement penalties for negligence start at 50% of the understated tax, and can reach 200% for intentional tax evasion
• Penalties and interest are not deductible as a business expense for income tax purposes

Understanding your exposure before the assessment arrives gives you time to plan.

Types of SARS Penalties

1. Administrative Penalties (Fixed-Amount)

These are levied for non-submission of returns. The fixed-amount penalty is determined by the taxpayer's assessed taxable income in the prior year:

Prior Year Taxable Income	Monthly Penalty Amount
R0 - R250,000	R250 per month
R250,001 - R500,000	R500 per month
R500,001 - R1,000,000	R1,000 per month
R1,000,001 - R5,000,000	R2,000 per month
Above R5,000,000	Up to R16,000 per month

Administrative penalties apply per outstanding return and can run for multiple months until the return is submitted.

2. Late Payment Penalties

A 10% once-off penalty is imposed on any tax not paid by the due date. This applies to:

• Income tax on assessment
• Provisional tax payments (first and second period)
• VAT payments
• PAYE payments

3. Understatement Penalties

These apply when SARS issues an additional assessment because the original return understated taxable income or overstated deductions:

Behaviour	Standard Rate	Repeat Offender
Reasonable care not taken	25%	50%
No reasonable grounds for position	50%	75%
Gross negligence	75%	100%
Intentional tax evasion	150%	200%

4. Specific Tax Penalties

• PAYE: 10% on underpaid PAYE per period
• VAT: 10% on the unpaid VAT balance
• Diesel refund fraud: 200% of the fraudulent claim

How to Use the SARS Penalty Calculator

Step 1: Open the Calculator

Navigate to the SARS Penalty Calculator.

Step 2: Select the Penalty Type

Choose from: administrative penalty (non-submission), late payment penalty, or understatement penalty. Each type uses a different calculation formula.

Step 3: Enter the Tax Details

• For administrative penalties: Enter the number of outstanding returns and the relevant prior-year taxable income band
• For late payment: Enter the outstanding tax amount and the number of days from the payment due date
• For understatement: Enter the understated amount and select the applicable behaviour category

Step 4: Enter the Date Range

The calculator uses dates to determine how many months of penalty have accumulated (for administrative penalties) or how many days of interest have accrued.

Step 5: Review the Estimate

The output shows:

• Penalty amount
• Estimated interest (at the prescribed rate, compounded monthly)
• Total estimated amount due

This is an estimate. The actual SARS assessment may differ based on the specific penalty rate applicable to your case and any adjustments SARS applies.

What Happens After You Get Your Estimate

If You Can Pay

Pay the outstanding tax plus the estimated penalty as soon as possible. Interest stops accruing on the penalty amount only once both are settled. Do not wait for SARS to issue a formal assessment — continued delay compounds the interest.

Applying for Penalty Remission

SARS will remit (reduce or cancel) a penalty if the taxpayer demonstrates "reasonable grounds" for the failure. Valid grounds include:

• Serious illness or incapacitation
• Natural disaster or fire affecting records
• SARS system failure preventing submission
• Incorrect information received from SARS

Remission is not automatic. You must submit a written request with supporting documentation. First-time offenders have a higher success rate for partial remission of administrative penalties.

Disputing the Penalty

If you believe the penalty was incorrectly calculated or should not have been imposed:

1. File a Notice of Objection (NOO) on eFiling within 80 business days of the assessment date
2. Clearly state the grounds for the objection and attach supporting evidence
3. SARS must respond within 60 business days
4. If SARS disallows the objection, you can appeal to the Tax Board (for amounts under R1 million) or the Tax Court

Common Mistakes That Trigger SARS Penalties

1. Submitting returns with no payment — the return clears the administrative penalty but the late payment penalty still applies
2. Not updating banking details on eFiling — SARS refunds go to the wrong account, delaying settlement
3. Provisional tax shortfall — if your second provisional payment is less than 90% of the actual tax liability, a penalty applies at assessment
4. Not registering for VAT on time — SARS can impose retrospective penalties from the date you should have registered
