Tax deductions and tax credits can both reduce your overall tax burden, but they work in very different ways. Understanding the difference can help taxpayers evaluate their tax situation and avoid overlooking benefits for which they may qualify.
What Is a Tax Deduction?
A tax deduction reduces the amount of income that is subject to federal income tax.
For example, if a taxpayer has $60,000 of taxable income and qualifies for a $5,000 deduction, the deduction can reduce taxable income to $55,000, subject to the applicable tax rules.
The value of a deduction depends partly on the taxpayer’s marginal tax rate.
Common deductions can include certain business expenses, student loan interest, IRA contributions, mortgage interest, charitable contributions, and other qualifying expenses.
Not every taxpayer can claim every deduction. Eligibility depends on the type of expense and the taxpayer’s circumstances.
What Is a Tax Credit?
A tax credit works differently. Instead of reducing taxable income, a tax credit generally reduces the amount of tax owed.
For example, if a taxpayer calculates $4,000 in federal income tax and qualifies for a $1,000 tax credit, the credit could reduce the tax liability to $3,000.
This is why tax credits can be particularly valuable.
Refundable vs. Nonrefundable Tax Credits
Tax credits can generally be divided into refundable and nonrefundable credits.
A nonrefundable tax credit can reduce tax liability, but generally cannot reduce the tax below zero.
A refundable tax credit can potentially provide a refund when the credit exceeds the taxpayer’s remaining tax liability, subject to the specific rules for that credit.
Some credits have both refundable and nonrefundable components or special limitations.
Standard Deduction vs. Itemized Deductions
Many taxpayers use the standard deduction rather than itemizing deductions.
The standard deduction is a predetermined amount that reduces taxable income for eligible taxpayers.
Itemizing involves listing qualifying deductible expenses individually.
Taxpayers generally compare the available standard deduction with their eligible itemized deductions when determining which approach provides the better result.
Common itemized deductions can include certain medical expenses, state and local taxes subject to applicable limits, mortgage interest, and qualifying charitable contributions.
Why Documentation Matters
Tax deductions and credits should be supported by appropriate records.
Depending on the situation, taxpayers may need documents such as:
- Receipts
- W-2 and 1099 forms
- Mortgage statements
- Donation records
- Education expenses
- Childcare records
- Business expense records
- Mileage documentation
- Investment records
Good documentation is especially important when claiming deductions or credits that depend on specific eligibility requirements.
Common Tax Filing Mistakes
One common mistake is assuming that every expense automatically qualifies for a deduction.
Another is confusing a tax deduction with a tax credit. They are not interchangeable.
Taxpayers may also overlook credits because they assume they do not qualify without reviewing the current requirements.
Using outdated tax information can create additional problems because tax laws and IRS rules can change.
How to Find Potential Tax Savings
A useful tax preparation process starts with reviewing all sources of income and then identifying deductions and credits that may apply.
Taxpayers should consider their filing status, dependents, income sources, investments, education expenses, homeownership, charitable contributions, retirement contributions, and business activities when reviewing their tax situation.
However, an expense or circumstance does not automatically qualify for a tax benefit simply because it appears on a general tax checklist.
Final Thoughts
The basic distinction is simple:
Tax deductions reduce taxable income. Tax credits generally reduce the tax itself.
Understanding that difference is an important part of tax planning and tax preparation. Before claiming a deduction or credit, taxpayers should verify the current IRS requirements and maintain documentation supporting their claim.
