And in that notice, it will be mentioned that from which time period they are going to need an Audit report of your company. After that making, this audit report is not a single day process, but actually, it will take several days, or maybe more than a week as well depending on how large your firm is. Basically, this whole process is divided into two categories. In the first category, the auditor will compare your filed Sales Tax Returns with the ledger. And this whole process will cover up all the records, sales tax, bank transactions, and documentation. This process makes sure that all the Sales Tax Return Filed are perfect and in order. Then in next category, the auditor will gather all the additional information about your company that includes agreements, certifications, and Sales Tax License, or any other information that is still under review about your company.
