A. The assembly may designate a person or firm to make investigations and inspections of the books and records of any persons, firms or corporations who are, or are reasonably believed to be, liable for taxes under this chapter. Such person shall be the sales tax inspector of the borough.

B. The sales tax inspector is hereby authorized and empowered to make inspections of all the books and records pertaining to purchases, sales, services and rents made, furnished, paid or performed by parties who are or may be liable for the tax levied under this chapter. These books and records include, but are not limited to, records of purchases made by retailers from wholesalers or other retailers, the ledger accounts of customers of the taxpayers, the sales slips made by taxpayers and all other books and records of the taxpayers which would in any way tend to prove or reveal information concerning the tax liability of the taxpayer.

C. It shall be the duty of every person engaged in retail business, or in furnishing services to the public in the borough, to allow the sales tax inspector to examine such books and records during regular business hours at such times as the sales tax inspector shall require. If the sales tax inspector shall find that unreported tax liabilities exist or that discrepancies in favor of the borough between the sales reported to the clerk and the sales which appear to have been made by any taxpayer, it shall be the duty of the clerk to demand by certified mail, return receipt requested, that the taxpayer forthwith make amended returns showing the correct amount of tax payable for each month for which such discrepancies appear and to pay the taxes due the borough.

D. Unless a taxpayer upon whom such demand is made shall make such returns and pay the taxes due the borough within 15 days from the date of the demand by the clerk, the clerk shall report the facts in full to the assembly. The clerk shall keep confidential all facts which have been learned as a result of such investigations until such time as the same are reported to the assembly.

E. In the event of a dispute between the taxpayer and the clerk as to the amount of tax due, the taxpayer may within five days of the demand made upon the taxpayer for the filing of amended returns and the payment of such taxes, demand a hearing before the assembly on the taxpayer’s tax liability. In such event, the assembly shall, at its next regular meeting, set a date for hearing within 15 days thereafter, and the clerk shall notify the taxpayer of the time and place at which such hearing will be held. The assembly shall, after receiving a report from the clerk of delinquent taxes and conducting a hearing, if the taxpayer demanded the same, take such action at law as is necessary to collect any taxes which the assembly shall find to be delinquent including interest payable.
