                            business apportionment formula consisting of the average of property, gross receipts, and wages paid may be used by 
                            business entities not required to pay tax on entire net profits by reason of doing business both inside and outside 
                            Dayton. However, if the books and records of the taxpayer shall disclose with reasonable accuracy the net profit 
                            attributable to Dayton then only this portion shall be considered as having a taxable situs in Dayton.

 Line 13:                   Balance Due Subtract Line 11 from Line 8, add total on Line 12, if required, to determine balance due. If Line 11 is 
                            more than Line 8, then an overpayment exists. Enter overpayment amount on Line 14. 

 Line 14:                   If Line 13 is $10.00 or more then you may have the overpayment applied to next tax year or refunded. Indicate your 
                            choice on Line 14. No indication will result in an overpayment credit to next tax year. Refunds will be processed in

                            estimated amounts for next tax year. 

 Line 16:                   Divide Line 15 by 4.

                            this return is applied to the first quarterly payment. If the overpayment is greater than the first quarterly payment, the 
                            difference will apply to the next quarter due.
