Introduction to Business Tax in South Africa

As an employee, your tax life was largely invisible. Your employer registered you, deducted the right amounts, submitted returns on your behalf, and issued a tax certificate at year-end. Your annual return was mostly a formality.

As a business owner, none of that happens automatically. Every registration is your responsibility. Every deadline is your responsibility. Every calculation is your responsibility. SARS does not send reminders, does not make allowances for first-year ignorance, and does not waive penalties because you did not know a return was due.

The system is logical once you understand it. This article maps every tax type your business may encounter, when it applies, and in what order to deal with it.

The South African Business Tax Landscape

There are seven tax and statutory obligations a business in South Africa may need to manage. Not all apply to every business. Which ones apply depends on your structure, your turnover, and whether you employ staff.

Most new businesses start with income tax and provisional tax only. VAT, PAYE, UIF, and SDL are added as the business grows. Dividends tax arises only when a PTY Ltd distributes profits to shareholders.

Each Tax Type Explained

Income Tax

Every business pays income tax on its profit. The rate and mechanism depend on your structure.

A sole proprietor declares business profit on their personal income tax return (ITR12) and pays tax at individual marginal rates. The tax-free threshold for the 2026/27 year is R99 000 for people under 65. Above that, rates run from 18% at the bottom bracket to 45% on income above R1.88 million. Every rand of profit is personal income in the year it is earned, regardless of whether you draw it out or reinvest it.

A PTY Ltd pays corporate income tax at 27% of taxable profit on its own company return (ITR14). Companies that qualify as Small Business Corporations pay significantly lower progressive rates, starting at 0% on the first R95 750 of taxable income for 2025/26. The SBC rates are updated annually.

Income tax registration is the foundation. Every other SARS registration requires it to exist first.

What catches new business owners: The tax-free threshold applies to total income, not just business income. If you are also earning a salary from another source, your business profit is stacked on top of it and taxed at the marginal rate that applies to the combined amount. A business making R400 000 profit does not necessarily pay tax at the 18% starting rate.

See KB-002 for full detail on business income tax.

Provisional Tax

Provisional tax is not a separate tax. It is the mechanism SARS uses to collect income tax during the year when you are not an employee subject to PAYE. Instead of one large bill at year-end, you make two estimated payments per year based on your projected annual taxable income.

The first payment is due at the end of August, the second at the end of February. You submit an IRP6 return with each payment. A third voluntary top-up payment is available by the end of September, which allows you to correct an underestimate and reduce interest exposure before SARS finalises your assessment.

Every business owner and every company is a provisional taxpayer from the first day of trading. There is no registration required separately; provisional tax status flows automatically from income tax registration once you earn non-salary income.

What catches new business owners: The money arrives in your account in full and feels like income. No one deducts the tax before it reaches you. If you do not set aside a provision from day one, you face a material payment obligation at the end of August with no accumulated cash to fund it. Many first-year business owners treat provisional tax as an unexpected bill rather than a predictable cost of the calendar.

The underestimation penalty is a separate problem. If your second provisional tax estimate falls more than 20% below your actual taxable income (for incomes above R1.8 million, more than 20% below 80% of actual income), SARS applies a penalty of 20% on the shortfall — in addition to the tax owed and interest. This is not a rounding issue; it is a penalty for deliberate or careless underestimation.

See KB-002 for full detail on provisional tax, payment calculations, and underestimation penalties.

VAT

VAT is a 15% tax on most goods and services. Once registered, your business collects VAT from customers on behalf of SARS, claims back the VAT it paid to suppliers, and pays the difference to SARS every one or two months via a VAT201 return.

Registration is compulsory once your taxable turnover exceeds R2.3 million in any consecutive 12-month period (threshold increased from R1 million on 1 April 2026). Voluntary registration is available from R120 000 turnover (increased from R50 000 on 1 April 2026).

What catches new business owners: The VAT collected from customers is not your money. It belongs to SARS from the moment it arrives in your account. Businesses that treat it as working capital face a VAT shortfall at return time. Late payment carries a 10% penalty plus interest. For a business collecting R100 000 in VAT per month, a two-month deficit is R20 000 in undeclared VAT — a R2 000 penalty plus growing interest.

Note that the registration threshold is a rolling 12-month window, not a calendar year. An unexpected large contract can push you over the threshold retrospectively. If you cross R2.3 million without registering, SARS can hold you liable for VAT on all sales from the point the threshold was crossed, whether you collected it from customers or not.

See KB-001 for full detail on VAT registration, tax invoice requirements, and the B2B versus B2C voluntary registration decision.

PAYE

The moment you hire an employee, you become responsible for calculating, deducting, and remitting their income tax to SARS every month. You pay it by the 7th of the following month through the EMP201 return. If you fail to deduct or remit PAYE, SARS holds the employer liable, not the employee.

PAYE also applies to you as a director drawing a salary from your own PTY Ltd. If you are the sole director of a PTY Ltd paying yourself a monthly salary, you are an employee for PAYE purposes. You must register as an employer even if you are the only person in the business.

What catches new business owners: Using deducted PAYE as short-term working capital is treated as a criminal offence under the Fourth Schedule to the Income Tax Act. Wilful or negligent failure to remit deducted PAYE carries a fine or imprisonment of up to two years. This is not a theoretical risk. The EMP201 is due monthly without exception.

See KB-003 for full detail on PAYE, the EMP201 process, and employer registration.

UIF

UIF provides income protection for employees who lose income through retrenchment, illness, or maternity. The contribution is 1% from the employee and 1% from the employer, totalling 2% of gross remuneration. Both portions are remitted by the employer through the monthly EMP201.

The employee portion is deducted from their salary. The employer portion is an additional business cost on top of the salary. Both go to SARS together.

UIF applies from the first employee. There is no minimum payroll threshold. The UIF ceiling for 2026/27 is R17 712 in monthly earnings, making the maximum UIF contribution R177.12 per party per month.

See KB-003 for full detail.

SDL

SDL is an employer-only levy of 1% of total monthly payroll. It applies only once your annual payroll exceeds R500 000. Below that threshold you register but submit nil returns.

SDL funds workplace training through the SETA system. If you are paying SDL, you can claim back a portion through your relevant SETA by submitting an annual Workplace Skills Plan and training report. Most small businesses paying SDL have never claimed a rand back because they do not know the mechanism exists.

See KB-003 for full detail.

Dividends Tax

When a PTY Ltd pays a dividend to shareholders, the company withholds 20% dividends tax and pays it to SARS on the shareholder's behalf. This is a separate event from corporate income tax. The company pays 27% on its profit first; when it distributes what remains to shareholders, dividends tax of 20% applies on the distribution.

The combined effective rate on profit fully extracted as dividends is approximately 41.6%. At R1 million of company profit, roughly R270 000 goes to corporate tax, leaving R730 000. A dividend of R730 000 attracts R146 000 in dividends tax, leaving the shareholder with R584 000. Understanding this mechanics matters when deciding how to structure salary versus dividends.

Dividends tax is not a registration. It is a withholding obligation that arises when a dividend is declared. Your accountant handles this as part of the dividend declaration process.

See KB-005 for full detail on salary versus dividends structuring.

The Registration Sequence

Tax registrations have dependencies. Registering in the wrong order creates delays. Follow this sequence.

Step 1: Income tax registration

This is always first. For a PTY Ltd, the income tax reference number is issued automatically when SARS is notified of the CIPC company registration, usually within a few days. Log into eFiling and confirm the number exists before attempting any other registration. For a sole proprietor, your existing personal income tax number is sufficient.

Step 2: Provisional tax

No separate registration is needed. Once you earn non-salary income, provisional tax applies automatically. What you need to do is know your first payment date and have a provisioning plan in place before that date arrives. The first payment is due at the end of August following the start of your tax year.

Step 3: VAT (if applicable)

Requires your income tax reference number. If registering voluntarily, register early. The process takes 5 to 21 business days, SARS may require a verification visit, and you cannot issue compliant VAT invoices or claim input VAT until the number is confirmed. Registering after you have already been trading creates a gap period where your invoices were not VAT-compliant.

Step 4: Employer registration — PAYE, UIF, SDL (if hiring)

Requires your income tax reference number. Register before you pay the first salary. The process takes a few days and you need an employer reference number to submit your first EMP201. If you register the day you pay salary, or after, you are already late and your first return will be outstanding.

How Your Tax Profile Evolves

Your obligations at startup are not what they will be at scale. The profile builds in layers.

Startup (sole proprietor or new PTY Ltd, no staff): Income tax registration and provisional tax. Nothing else unless you choose voluntary VAT registration. This is the simplest tax profile. Two obligations, one set of returns per year.

Approaching or crossing R2.3 million turnover: Compulsory VAT registration. Monthly or bi-monthly VAT201 submissions added to your calendar. This is where most business owners first engage an accountant. The administrative load increases materially.

Hiring the first employee: PAYE, UIF, and SDL obligations begin. Monthly EMP201 submissions. Bi-annual EMP501 reconciliation in October and May. IRP5 certificates for every employee at year-end. Payroll software becomes essential. Manual PAYE calculation for even one employee carries compliance risk.

Annual payroll exceeding R500 000: SDL activates at 1% of payroll. Register with your relevant SETA and begin tracking training spend so you can recover SDL contributions through the annual claims process.

PTY Ltd declaring its first dividend: Dividends tax of 20% must be withheld. Your accountant handles this as part of the declaration. Understand the combined effective rate before you decide on the dividend amount.

The Tax Calendar

Note: when a deadline falls on a weekend or public holiday, it moves to the preceding business day. SARS confirms filing season dates annually, typically in June or July. Never rely on memory for tax deadlines.

What Non-Compliance Actually Costs

SARS penalties are automatic. They are not discretionary, they are not negotiable after the fact, and they do not pause while you resolve the underlying issue.

Not registering as a provisional taxpayer: SARS estimates your income and raises an assessment. You owe tax, interest from the original due date, and administrative penalties. There is no relief for ignorance.

Missing a provisional tax payment or underestimating materially: 20% underestimation penalty on the shortfall, plus interest at 10.25% per annum from the due date.

Spending VAT collected from customers: When the VAT201 is due, the cash is not there. 10% penalty plus interest compounds monthly until the debt is settled. A business short by R50 000 in VAT faces a R5 000 penalty immediately, then interest on R55 000 the following month.

Missing PAYE registration while staff are working: Employer is liable for all PAYE that should have been deducted from the start of employment, plus penalties and interest. SARS does not pursue employees for tax their employer failed to deduct.

Late EMP201 submission or payment: Automatic 10% penalty on the outstanding amount plus 7% monthly interest.

Late EMP501 submission: 1% of annual PAYE liability per month outstanding, escalating by 1% monthly to a maximum of 10%. On a business with R500 000 annual PAYE liability, three months late costs R15 000 before interest.

Missing the CIPC annual return: Late penalties from CIPC, and eventually deregistration. Reinstating a deregistered company is slow, administratively painful, and costs more than the original annual return.

The cost of proper compliance from day one — an accountant, payroll software, a compliance calendar — is a fraction of the cost of correcting non-compliance after the fact.

Do You Need an Accountant?

Yes, with one qualification on timing.

In the very early stages — sole proprietor, no staff, turnover below the VAT threshold, no PTY Ltd — a motivated business owner can manage their own tax obligations. The obligations are limited, the calculations are manageable, and good software handles most of the mechanics.

The moment any of the following apply, engage a qualified accountant before the fact, not after:

• You incorporate a PTY Ltd
• You register for VAT
• You hire your first employee
• Your taxable income exceeds R500 000
• You are unsure about any of your current obligations

The cost of a small business accountant — typically R1 500 to R5 000 per month depending on complexity — is tax deductible and is almost always recovered through correct tax planning, avoided penalties, and deductions you would not have known to claim.

Use a registered tax practitioner or a CA(SA) with small business experience. Ask for referrals from other business owners in your network. Do not choose based on price alone. An accountant who is cheap because they are inexperienced with your type of business is not cheap.
