Individuals are always looking for tax deductions that can reduce their tax liability. But what is the actual tax benefit derived from a tax deduction? There is no straightforward answer because some deductions are above the line, others must be itemized, some must exceed a threshold amount before being deductible, and certain ones are not deductible for alternative minimum tax purposes, while business deductions can offset both income and self-employment tax. In other words, there are many factors to consider, and the tax benefits differ for each individual, depending on his or her particular situation and tax bracket.
For most non-business deductions, the savings are based upon your tax bracket. For example, if you are in the 12% tax bracket, a $1,000 deduction would save you $120 in taxes. On the other hand, if you are in the 32% tax bracket, the $1,000 deduction will save you $320 in taxes. Even so, if your taxable income is close to transitioning into the next-lower tax bracket, the benefit will be lower. You also need to consider whether the particular deduction is allowed on your state return and what your state tax bracket is to determine the total tax savings. Currently, the maximum federal tax bracket is 37%, meaning the most benefit that can be derived from a $1,000 income tax deduction is $370. Some individuals justify making discretionary purchases just because they are tax-deductible. Even in the highest tax bracket, you are still paying $630 out of pocket ($1,000 − $370), so it does not make sense to incur a tax-deductible expense just for the tax deduction.
