How this service works
Add VAT to a net amount or remove VAT from a gross amount. Standard VAT rates for 36 countries are built in, or override with any custom rate. Use this when an agent needs to add or remove VAT at standard rates for 36 countries.
Output
Returns the computed VAT amount, the resulting net or gross figure, the VAT rate applied (either the built-in standard rate for the selected country or the provided custom rate), and the direction of the operation (add or remove).
Example use cases
Invoice pricing for EU freelancer
“I need to add the standard French VAT rate to my net invoice amount of 840 euros — what's the VAT amount and the gross total I should charge my client?”
Reverse VAT on UK receipt
“I bought something in the UK for £119.99 including VAT — can you remove the VAT and tell me what the net price and the VAT amount were?”
Custom rate VAT calculation
“Calculate VAT on a net amount of 500 dollars using a custom rate of 12.5% — I want to add VAT and see the final gross price.”
Technical details
Endpoint
GEThttps://agenttools-hub.vercel.app/api/v1/calculators/vat-calculator?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, reliable VAT computation for one of the 36 built-in countries without maintaining your own tax-rate tables, or when you need to apply a custom rate. It handles both forward (net-to-gross) and reverse (gross-to-net) VAT calculations in a single call. Prefer it over generic math calculators because it encodes standard country VAT rates and handles the reverse-VAT formula correctly.
Side effects
- Missing required 'amount' parameter returns a validation error
- Invalid or unsupported country code not in the 36-country enum returns an error
- Providing neither 'country' nor 'rate' may use a default or return an error depending on implementation
- Non-numeric or negative amount values may cause a validation failure
- Ambiguous operation direction (missing 'op') may default to 'add' or return an error
