Question

1.         The three tax structures --- progressive, proportional, and regressive.  

            The classification of tax structures is based on the behavior of the average tax rate (ATR) or the     proportion of income paid in taxes. The following table shows three tax schedules. Calculate the ATR.

            Tax base using Tx paid                                   Tx paid                                     Tx paid

            taxable income tax A       ATR                        tax B         ATR                         tax C       ATR    

                       

            a.   $10,000       $   650      ____%                      $   500      ____%                     $1,000    ____%     

            b.   $20,000       $   850      ____%                     $1,000      ____%                      $3,000    ____%

            c.   $30,000       $   950      ____%                     $1,500      ____%                      $6,000    ____%

            d.   $40,000       $1,050      ____%                     $2,000      ____%                      $9,500    ____%

            e.         Tax schedule A indicates a _________________________ tax structure,

                                    because the ATR _________________________ as income increases.

            f.          Tax schedule B indicates a _________________________ tax structure,

                                    because the ATR _________________________ as income increases.

            g.         Tax schedule C indicates a _________________________ tax structure,

                                    because the ATR _________________________ as income increases.

Explanation / Answer

Average tax rate (ATR) = Tax paid / Taxable income

(a) to (d) - As follows

(e)

Tax schedule A indicates Regressive tax structure, because ATR decreases as income increases.

(f)

Tax schedule B indicates Proportional tax structure, because ATR is constant as income increases.

(g)

Tax schedule C indicates Progressive tax structure, because ATR increases as income increases.
