This gem scrapes US tax rates for individual states or the whole country.

Add this line to your application's Gemfile:

gem 'taxing'

And then execute:

$ bundle

Or install it yourself as:

$ gem install taxing

The rates are returned as hashes with the following keys as symbols:

state
zip_code
tax_region_name
tax_region_code
combined_rate
state_rate
county_rate
city_rate
special_rate

Here's an example of one rate:

{
  :state=>"CA",
  :zip_code=>"90001",
  :tax_region_name=>"LOS ANGELES COUNTY",
  :tax_region_code=>"AHBG",
  :combined_rate=>"0.090000",
  :state_rate=>"0.065000",
  :county_rate=>"0.010000",
  :city_rate=>"0",
  :special_rate=>"0.015000"
}

To load all of the rates for one state:

Taxing::Rate.state("CA")
> [{...}, ...]

To load all of the rates for the USA:

Taxing::Rate.all
> [{...}, ...]

The methods above can optionally take a Time instance as the second argument, and the gem will look up tax rates from that time. They may not all be available. If you get an error when trying to load rates, try passing in a Time object for 1 month ago, e.g., Taxing::Rate.state("CA", 1.month.ago) (assuming Rails).

This gem is not intended to be used as an API. You should scrape the rates periodically and cache them locally.

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
