About VAT Calculator
Hi, I'm Emam. I built this site.
A few months ago I needed to work out the VAT on a client invoice and found myself bouncing between three different calculators — one didn't have my country, one had outdated rates, and the third made me click through five steps to add 20% to a number. The whole time I kept thinking: this should take five seconds, not five minutes.
So I built one. The first version was just a UK calculator for myself. Then I added a few other countries. Then I realized a lot of freelancers and small businesses probably hit the same problem I did — especially people working across borders, where you might invoice a UK client one week and a UAE client the next, and the rates and rules are completely different.
The goal of this site is simple: a fast, accurate VAT calculator that works for any country, with content written for people running their own business — not for accountants and not for tax law students.
What you'll find here
- A calculator that handles add VAT, remove VAT, and "what's the VAT portion of this gross amount" — the three things people actually need
- Country-specific pages for the UK, EU, UAE, Bangladesh, Australia and more, each with the current standard rate, reduced rates, and registration threshold
- A custom rate option for any country I haven't built a dedicated page for yet
- Plain-English guides on things like "do I need to register for VAT" and "how do I write a VAT-compliant invoice"
What this site is not
This is not tax advice. I'm not an accountant and I'm not a tax lawyer. The calculator does math correctly, but whether you need to register for VAT, what rate applies to your specific product or service, and how to handle cross-border transactions — those are questions that depend on your situation, and you should talk to a qualified accountant or your country's tax authority.
I try to keep the rates and registration thresholds on the country pages accurate and up to date, and I cite the official source for each one. But tax rules change, and there's always a chance something on the site is out of date or wrong. If you spot an error, please let me know.
How I keep the data accurate
I check the rates and registration thresholds for the supported countries against the official tax authority websites at least once per quarter, and update the "verified" date on each country page when I do.
If a country has had a recent rate change or threshold update that I haven't reflected yet, please email me and I'll prioritize updating it.
How we source rates
Every verified country page on this site cites a single source: the official government tax authority for that country. If you click "source: HMRC" on the UK page, you go to gov.uk. If you click "source: ZATCA" on the Saudi Arabia page, you go to zatca.gov.sa. If you click "source: GST Council" on the India page, you go to gst.gov.in.
That's a deliberate policy. Tax aggregator sites and consultancy summaries are useful for cross-referencing, but they're not the authority — the government is. So we don't cite them as sources.
This rule has a consequence: if I can't find a clear, current rate published by the country's official tax authority, I don't claim verification. Right now this affects two countries in the dropdown:
- Vietnam — the legal standard rate is 10%, but a temporary 8% rate has been in effect since 2022 and extended through end of 2026. The "real" answer depends on what you're asking, so I leave it flagged as not independently verified.
- Canada — federal GST is 5%, but provinces add HST or PST that combine to anywhere from 5% to 15%. The federal rate alone could mislead someone in Ontario or Quebec, so I leave it flagged.
If you find a rate on this site that doesn't match the official source, please email me. Inaccurate tax information is the one thing this site cannot afford to be casual about.
