Before calculating, confirm your company qualifies as an SBC:

If any box is unchecked, this calculator will show your standard CIT liability instead, since SBC rates would not legally apply.
Tax payable R 0
Effective tax rate 0.00%
Standard CIT on this income would be R0 — you save R0 as a qualifying SBC

Which tax regime applies to your company?

Standard CIT SBC Turnover Tax
Rate structure Flat 27% Progressive: 0%–27% 0%–3% of turnover
Best for Most companies Small companies meeting all 5 SBC criteria Micro businesses, simple operations
Turnover/income limit None Gross income ≤ R20 million Annual turnover ≤ R2.3 million
Calculated on Taxable income (profit) Taxable income (profit) Turnover (revenue)
Files ITR14 ITR14 (at SBC rates) TT03

Rule of thumb: If you're unsure, start with Standard company in the calculator above — it's the default and always legally available. Only select SBC if you can tick all 5 qualification boxes, and only select Turnover Tax if your turnover is genuinely R2.3 million or less and you've elected into that system with SARS.

How each tax regime is calculated

Standard CIT (27% flat)

Tax payable = Taxable income × 27%

Example: R800,000 taxable income × 27% = R216,000

SBC (progressive rates)

Taxable income Rate
R0 – R99,000 0%
R99,001 – R365,000 7% of the amount above R99,000
R365,001 – R550,000 R18,620 + 21% of the amount above R365,000
Above R550,000 R57,470 + 27% of the amount above R550,000
Example: R400,000 taxable income → R18,620 (on R99,001–R365,000) + 21% × R35,000 (R7,350) = R25,970

Turnover Tax (percentage of revenue)

Turnover Tax is calculated directly on annual turnover (revenue), using a sliding scale starting at 0% on the first R600,000 and rising to a maximum of 3% above R1.5 million, up to the R2.3 million threshold.

What counts as "taxable income"?

For Standard CIT and SBC calculations, enter your taxable income — not your revenue or turnover. Taxable income is calculated as:

Gross income − Exempt income − Allowable deductions = Taxable income

Allowable deductions include costs incurred in producing income, such as cost of sales, salaries, rent, interest on business debt, and wear-and-tear on assets.

Source: Income Tax Act 58 of 1962, Section 11; SARS — Corporate Income Tax page

The common mistake: Entering your company's total revenue (rather than profit after deductions) into the Standard or SBC calculator fields will significantly overstate your tax liability. If you're calculating Turnover Tax, that mode correctly uses turnover/revenue directly — this is the one regime where revenue is the right input.

Frequently Asked Questions

The standard Corporate Income Tax (CIT) rate is 27% flat, unchanged for years of assessment ending 1 April 2026 to 31 March 2027 — Budget 2026 announced no change. Companies that qualify as a Small Business Corporation (SBC) pay progressive rates instead: 0% on the first R99,000, rising to a maximum of 27% above R550,000. Companies in approved Special Economic Zones may qualify for a reduced 15% rate.

Your company qualifies as an SBC only if it meets all 5 criteria: it is a private company, close corporation, personal liability company, or co-operative; gross income is R20 million or less; all shareholders/members are natural persons; the company is not a Personal Service Provider; and investment income plus personal service income does not exceed 20% of total receipts (unless the company employs 3 or more full-time, non-shareholder employees). All criteria must be met for the relevant year of assessment.

For Standard CIT and SBC calculations, enter your taxable income (revenue minus allowable business deductions) — not your total turnover or revenue. Entering revenue instead of taxable income will significantly overstate your tax liability. For Turnover Tax calculations, enter your annual turnover directly — this is the one regime calculated on revenue rather than profit.

Turnover Tax is a simplified tax system for micro businesses with annual qualifying turnover not exceeding R2.3 million (increased from R1 million, effective 1 March 2026). It is calculated directly on turnover rather than profit, using rates from 0% (on turnover up to R600,000) to a maximum of 3%. It replaces income tax, provisional tax, and CGT, though a business can elect to remain VAT-registered. Personal service providers and labour brokers are excluded from Turnover Tax.

The saving depends on your taxable income level. For example, a company with R400,000 in taxable income pays approximately R25,970 in tax as a qualifying SBC, compared to R108,000 under the standard 27% CIT rate — a saving of about R82,000. Savings are largest for companies with taxable income below R550,000, since SBC rates converge with the standard 27% rate above that threshold.

This calculator provides an estimate based on the SARS 2026/2027 rates for illustrative purposes. Your actual ITR14 filing requires your complete, accurately calculated taxable income (after all applicable deductions, capital allowances, and elections) and must be submitted via SARS eFiling within 12 months of your company's financial year-end. Use this calculator to estimate and plan, not as a substitute for your actual tax return.
