NEW YORK (MainStreet) — When you claim a tax deduction on Schedule A, for example state and local income taxes withheld, you receive a "tax benefit," because the deduction has reduced your taxable income and therefore your tax liability. The tax benefit is the lessor of the actual deduction claimed or the amount the deduction causes your total itemized deductions to exceed your applicable Standard Deduction amount.

If you receive a refund of all or part of a deduction you claimed, for example a state tax refund, you must report as income the amount of tax benefit you had received from the amount of the refund.

For example - you deducted $1,000 in state income taxes on your 2012 Schedule A. This represents the total amount of state income tax withheld from your wages in 2012 from your Form W-2. When you filed your 2012 state income tax return you were entitled to a refund of $300, which you received. All or part of the refund must be reported as income on Line 10 of your 2013 Form 1040.

If you filed your return as Single your Standard Deduction for 2012 was $5,950. If the total amount of your itemized deductions for 2012 was $7,000 you must report as income the full $300 state tax refund on your 2013 return.

If the total amount of itemized deduction for 2012 was $6,175, you only have to claim $225 of the refund as income in 2013. The $1,000 deduction for state and local income taxes you claimed on the 2012 Schedule A caused your total deductions to exceed the Standard Deduction by $225. So the tax benefit you received from the $300 refund was only $225.
