Answer:
$7,580
Step-by-step explanation:
In April of this year, Tim paid $1,160 with his state income tax return for the previous year.
Tim had $5,200 of state income tax
Tim made estimated payments of $1,220 of state tax.
Therefore:
$1,160 + $5,200 +$1,220=$7,580
Tim can deduct the state taxes paid with state income tax return for the previous year, state tax which was withheld during the year, and estimated payments of state tax, a total of $7,580 in which the expected refund next year will not affect the deductions for this year, due to the fact that it may be taxable next year under the tax benefit rule.
