Answer:
$900
Explanation:
IN THIS QUESTION, WE ARE ASKED TO CALCULATE BY WHICH AMOUNT WOULD MRS WASHINGTON TAX AMOUNT BE REDUCED.
WE PROCEED AS FOLLOWS;
Last year tax liability = 48000*20/100 = $9600
current contribution towards IRA = $3000
Let us assume this year taxable income is also $48000
Now, we calculate net taxable income = 48000 - 3000 = 45000
therefore current year tax liability = 45000*20/100 = $9000
so reduction in tax liability = 9600 - 9000 = $900
