If you are a newly registered service provider or manufacturer, excise audit may be new to you .. Generally, excise audit is undertaken by the govt. as per the norms of excise duty amount that you paid during previous year .. Forms are sent to you for filling in and return.. If sufficient checks and balances are found in your accounting system that may not alert for any revenue leak for excise, then frequency of audit will be reduced.. Only the private records maintained by you or statutory records as per the business / corporate laws are taken for audit.
