Suppose a person buys something on a sales tax holiday.
Will that change his federal tax or state/local tax?
Does it mean that sales tax holiday only affects his state tax?
Do New York State and City have sales tax holiday?
If sales tax holiday affects his federal tax, will the expense of the purchase become
- a deduction when calculating his adjusted gross income, or
- a deduction in his itemized deductions, or
- a tax credit?
