+=head1 NAME
+
+FS::tax_class - Object methods for tax_class records
+
+=head1 SYNOPSIS
+
+  use FS::tax_class;
+
+  $record = new FS::tax_class \%hash;
+  $record = new FS::tax_class { 'column' => 'value' };
+
+  $error = $record->insert;
+
+  $error = $new_record->replace($old_record);
+
+  $error = $record->delete;
+
+  $error = $record->check;
+
+=head1 DESCRIPTION
+
+An FS::tax_class object represents a tax class.  FS::tax_class
+inherits from FS::Record.  The following fields are currently supported:
+
+=over 4
+
+=item taxclassnum
+
+Primary key
+
+=item data_vendor
+
+Vendor of the tax data
+
+=item taxclass
+
+Tax class
+
+=item description
+
+Human readable description of the tax class
+
+=back
+
+=head1 METHODS
+
+=over 4
+
+=item new HASHREF
+
+Creates a new tax class.  To add the tax class to the database, see L<"insert">.
+
+Note that this stores the hash reference, not a distinct copy of the hash it
+points to.  You can ask the object for a copy with the I<hash> method.
+
+=cut
+
+sub table { 'tax_class'; }
+
+=item insert
+
+Adds this record to the database.  If there is an error, returns the error,
+otherwise returns false.
+
+=cut
+
+=item delete
+
+Delete this record from the database.
+
+=cut
+
+=item replace OLD_RECORD
+
+Replaces the OLD_RECORD with this one in the database.  If there is an error,
+returns the error, otherwise returns false.
+
+=cut
+
+=item check
+
+Checks all fields to make sure this is a valid tax class.  If there is
+an error, returns the error, otherwise returns false.  Called by the insert
+and replace methods.

+  $self->SUPER::check;

+
+=item batch_import
+
+Loads part_pkg_taxrate records from an external CSV file.  If there is
+an error, returns the error, otherwise returns false.
