You'll likely have heard about the impending doom changes which will hit EU tech businesses in January 2015. At present, there is no government sponsored API for accessing the current VAT rates for a given country. This very simple Ruby client allows you to access up-to-date VAT rates for any EU country.
This uses the jsonvat.com service to obtain its data. Full details can be seen here.
This information is provided on an as-is basis. The authors or contributors cannot be held responsible for its accuracy or completeness. You use the data provided by jsonvat.com entirely at your own risk.
The API returns the standard & reduced VAT rates for EU countries. In some circumstances, you may need to charge other rates for certain types of product. For a full list, see this document.
gem 'json_vat', '~> 1.0'
You can look up the current rate for any country by providing it's ISO-3166-1-alpha2 code, like so.
JSONVAT.country('GB').rate #=> 20.0
JSONVAT.country('GB').rate(:reduced) #=> 5.0
If you want to look up the rate for a different time:
date = Date.new(2005, 1, 5)
JSONVAT.country('GB').rate_on(date) #=> 20.0
JSONVAT.country('GB').rate_on(date, :reduced) #=> 5.0
If a country doesn't exist, nil will be returned from the call to the country
method. If no rate is found, nil will be returned from the rate
or rate_on
methods.
By default, this will cache the contents of the rates array in a temporary file
in /tmp/jsonvat.json
. If this file exists, any future reads will be taken from
this file.
# Recache the rates from jsonvat.com. This should be scheduled to run on a semi
# regular basis. If you are setting this up on a cron, please run this at a random
# time to avoid load on our servers at peak times (like midnight).
JSONVAT.cache
# To download the current rates manually, you can use this method. This will return
# a string of the data currently available on jsonvat.com
JSONVAT.download
# Disable caching and always download the latest data from jsonvat.com
JSONVAT.cache_file = nil
If you need to change the cache path, you can do so with this command:
JSONVAT.cache_file = File.join('other', 'path', 'rates.json')
