About VATmatics
Free VAT calculators and business tools built for South African businesses
Why we built VATmatics
Every online VAT calculator we tested was built for the UK (20% VAT) or Europe. South Africa uses 15% — every foreign tool gives the wrong answer for SA businesses. VATmatics was built from scratch using the correct SA VAT rate, SARS rules, and South African invoice standards.
Our tools are used by freelancers, small business owners, retailers, contractors, and accountants across South Africa. Everything runs in your browser — no data ever leaves your device.
