Newest AvaTax version (3.5.3) does not need this patch Works with Firecheckout 4.2.3

1. Open app/code/community/OnePica/AvaTax/etc/config.xml and find the following code:

   <sales_quote_collect_totals_before>
       <observers>
           <avatax>
               <type>singleton</type>
               <class>avatax/observer</class>
               <method>salesQuoteCollectTotalsBefore</method>
           </avatax>
       </observers>
   </sales_quote_collect_totals_before>
   

   Replace it with:

   <sales_quote_address_collect_totals_before>
       <observers>
           <avatax>
               <type>singleton</type>
               <class>avatax/observer</class>
               <method>salesQuoteCollectTotalsBefore</method>
           </avatax>
       </observers>
   </sales_quote_address_collect_totals_before>
   <!-- <sales_quote_collect_totals_before>
       <observers>
           <avatax>
               <type>singleton</type>
               <class>avatax/observer</class>
               <method>salesQuoteCollectTotalsBefore</method>
           </avatax>
       </observers>
   </sales_quote_collect_totals_before> -->
   

2. Open app/code/community/OnePica/AvaTax/Model/Observer.php and find the following code:

   $storeId = $observer->getEvent()->getQuote()->getStoreId();
   if (Mage::getStoreConfig('tax/avatax/action', $storeId) != OnePica_AvaTax_Model_Config::ACTION_DISABLE) {
   

   Replace it with:

   // $storeId = $observer->getEvent()->getQuote()->getStoreId();
   $storeId = $observer->getEvent()->getQuoteAddress()->getQuote()->getStoreId();
   if (Mage::getStoreConfig('tax/avatax/action', $storeId) != OnePica_AvaTax_Model_Config::ACTION_DISABLE) {
