Spanish IVA Calculator (VAT Spain)
Use this calculator to quickly add IVA to a net amount or remove IVA from a gross amount. Supports the most common Spanish VAT rates: 21%, 10%, and 4%, plus a custom rate.
How the Spanish IVA calculator works
IVA (Impuesto sobre el Valor Añadido) is the value-added tax used in Spain. Businesses and freelancers commonly need to calculate it when creating invoices, checking receipts, preparing budgets, or validating supplier bills. This Spanish IVA calculator helps you do that in seconds with consistent formulas and clear outputs.
The tool supports two practical modes:
- Add IVA: You enter a net amount (base imponible), and the calculator returns IVA amount + total (gross).
- Remove IVA: You enter a gross total (precio con IVA), and the calculator extracts the base amount and IVA included.
Common IVA rates in Spain
Spain generally applies several VAT rates depending on product or service type. In many day-to-day calculations, these are the rates users need most often:
- 21% (general rate): The default for many goods and professional services.
- 10% (reduced rate): Often used for selected food items, passenger transport, some hospitality services, and specific categories set by law.
- 4% (super reduced rate): Typically for essential goods like basic foods, some books, and certain social-interest products.
- 0% or exempt: Specific transactions may be exempt or zero-rated under legal conditions.
Important: Tax laws can change. Always verify final invoice treatment with current Agencia Tributaria guidance or your accountant.
Formulas used
1) Add IVA to a net price
If you start with a net amount:
- IVA amount = Base × (Rate / 100)
- Total with IVA = Base + IVA amount
2) Remove IVA from a gross price
If you start with a total that already includes IVA:
- Base amount = Total / (1 + Rate / 100)
- IVA amount = Total − Base amount
Example calculations
Example A: Add 21% IVA to €100
