Icms

Icms implements the new icms tax table between states http://guiatributario.net/2015/04/20/nova-sistematica-de-recolhimento-do-icms-interestadual-a-partir-de-16072015/.

Installation

Add this line to your application's Gemfile:

gem 'icms'

And then execute:

$ bundle

Or install it yourself as:

$ gem install icms

Usage

First of all create a new instance of Icms::States passing the taxes rates and the separator. example:

state_rates = Icms::StateRates.new

# Use get_percentual to get the value between two states
puts state_rates.get_percentual(:SP, :AC) # 7.0
puts state_rates.get_percentual(:AC, :SP) # 12.0

# Passing only source state will return that state rate
puts state_rates.get_percentual(:SP) # 18.0

# To obtain all informations about the source and destination state use `get`
result = state_rates.get(:AC, :SP) # <destination_state=18.0, source_state=17.0, between=12.0>
puts result.source_state # AC: 17.0
puts result.destination_state # AC: 18.0
puts result.between # AC -> SP: 12.0



# You can use a custom rates table instead of using the default table in Icms module
# Rates table
TABLE = <<-TABLE
