Package for validating VAT numbers & retrieving VAT rates (from [ibericode/vat-rates](https://github.com/ibericode/vat-rates)) in Go.

## Installation

Use go get.

```

go get github.com/dannyvankooten/vat

```

Then import the package into your own code.

```

import "github.com/dannyvankooten/vat"

```

## Usage

### Validating VAT numbers

VAT numbers can be validated by format, existence or both. VAT numbers are looked up using the [VIES VAT validation API](http://ec.europa.eu/taxation_customs/vies/).

```go

package main

import "github.com/dannyvankooten/vat"

func main() {

  // Validate number by format + existence

  validity, err := vat.ValidateNumber("NL123456789B01")

  // Validate number format

  validity, err := vat.ValidateNumberFormat("NL123456789B01")

  // Validate number existence

  validity, err := vat.ValidateNumberExistence("NL123456789B01")

}

```

### Retrieving VAT rates

> This package relies on a [community maintained repository of vat rates](https://github.com/ibericode/vat-rates). We invite you to toggle notifications for that repository and contribute changes to VAT rates in your country once they are announced.

To get VAT rate periods for a country, first get a CountryRates struct using the country's ISO-3166-1-alpha2 code.

You can get the rate that is currently in effect using the `GetRate` function.

```go

package main

import (

  "fmt"

  "github.com/dannyvankooten/vat"

)

func main() {

  c, err := vat.GetCountryRates("NL")

  r, err := c.GetRate("standard")

  fmt.Printf("Standard VAT rate for NL is %.2f", r)

  // Output: Standard VAT rate for NL is 21.00

}

```
