Miss. Code § 83-1-31
When, in the judgment of the Insurance Commissioner, or upon request by the State Tax Commission, an audit, examination, or inspection of the books, records, invoices, papers, memoranda, or other data appears to be required or necessary to determine the assessment of a tax, or to establish a tax liability, or to verify a payment of a tax, under the tax laws of this state, of a taxpayer doing business both within and without the state and maintaining his principal place of business outside the state, such audit, or examination, or inspection may be made at the principal place of business outside the state to the same extent and same effect as audits, examinations, or inspections are made of books, records, invoices, papers, memoranda, or other data located in this state.
The Insurance Commissioner, who is directly charged with the duty of auditing the records necessary for use by the State Tax Commission in assessing and collecting taxes under laws which require a taxpayer to keep adequate books, records, papers, invoices, memoranda, or other data at a place in this state, reflecting his liability for any tax due the state, and which taxpayer conducts his business both within and without Mississippi and maintains his principal place of business outside this state, at which his books, records, etc., are located, may elect to audit, examine, or inspect all books, records, papers, invoices, memoranda, or other data reflecting upon the Mississippi tax assessment and tax liability at the principal place of business of the taxpayer, rather than require the taxpayer to transport all of his books, records, papers, invoices, memoranda, and other data to some place in this state.
