UK VAT Calculator 2026 — Add or Remove VAT at 20%, 5% & 0% (HMRC Compliant)

It works out Value Added Tax (VAT) in the UK by calculating the VAT amount, net price, and gross price. You can add VAT to a net price or extract VAT from a gross price. The results are indicative estimates, not legal or tax advice.

Yes — it's built for UK businesses, freelancers, online sellers, and contractors who need quick VAT figures in GBP (£), and it helps estimate invoice totals and the VAT split for pricing and bookkeeping. Always confirm final VAT reporting against HMRC guidance or with a qualified accountant.

The VAT maths is accurate when you enter the correct rate and pricing type (net or gross). Real-world compliance can still depend on product category, place-of-supply rules, and exemptions, so use it for estimation and check official requirements where needed.

Enter the net price and VAT rate to estimate the VAT amount and total gross price — handy for invoices, quotes, and pricing updates. Doing it here is instant and avoids manual calculation errors.

Enter the gross (VAT-inclusive) amount and the VAT rate to estimate the net price and the VAT portion, which is useful for reconciling receipts or supplier invoices that include VAT. Extracting VAT this way is quick, but keep the original invoice records for compliance.

VAT applies across the UK, but Northern Ireland can have specific VAT treatment for certain goods movements because of post-Brexit trade arrangements. In practice, most invoicing uses the same calculation method — the tool handles the maths, while the rules should be confirmed against HMRC guidance.

No. VAT rates don't change by city in the UK — London and Birmingham apply the same rates. What differs is business pricing, overheads, and consumer costs. The calculation works the same for any UK location in GBP (£).

A common one is confusing net with gross pricing and quoting the wrong invoice total to clients. Another is assuming every product or service is taxable at the same rate. Automating the maths reduces calculation errors, but category rules still need checking.

No. The UK has different VAT rates, and some goods and services are reduced-rated, zero-rated, or exempt. Assuming 20% for everything can cause pricing and reporting errors, so apply the correct rate for your scenario.

Use the result as a breakdown of net price, VAT portion, and gross total in GBP (£) — especially helpful for pricing decisions, invoices, and quick checks during bookkeeping. Final VAT reporting should follow HMRC rules and your accounting method.

It doesn't determine whether something is VAT-exempt, reverse-charge applicable, or subject to special schemes, and it doesn't handle VAT thresholds, registration decisions, or VAT returns. Results are indicative and for calculation support only.

HMRC sets the official rules for VAT rates, registration, and reporting, including what counts as a taxable supply. This tool follows standard VAT maths but isn't an HMRC product, so check HMRC guidance or speak with an accountant for compliance and edge cases.

Yes — VAT rules and rates can change with government policy, which is why it's worth reviewing your rate assumptions each year and applying the current VAT rate for your goods or services.

Yes. If you run a UK business from overseas, you can estimate invoice totals in GBP (£) here. Your VAT obligations may depend on business registration, place of supply, and customer location, so treat the results as indicative and verify them for compliance.

If you receive payments in another currency, exchange rates affect the GBP amount you record for VAT purposes. Compute VAT correctly in GBP first — that's what matters for UK accounting — then allow an FX buffer and keep records of conversion rates and fees.

Cross-border services, digital products, import/export situations, and reverse-charge transactions can all require special VAT treatment and additional reporting beyond simple maths. The tool handles the numbers, but check the rules carefully in these cases.

Not always, but it can still help when you're comparing supplier pricing or planning for registration. Many businesses underestimate how VAT affects cash flow once they cross the registration threshold, so modelling pricing early is worthwhile.

Keep consistent records of net sales, VAT collected, and VAT paid on eligible expenses, and set money aside for VAT monthly so return time isn't stressful. For reporting accuracy, consider accounting software or a qualified accountant.
