Deductions and exemptions pertain to amounts that taxpayers can subtract from their gross income to calculate their taxable income. These mechanisms are critical for reducing overall tax liability for both individuals and businesses.
What Are Deductions?
Deductions are specific expenses that the tax code allows you to subtract from your gross income to arrive at your adjusted gross income (AGI). Common deductions include:
- Standard Deduction: A fixed dollar amount that non-itemizing taxpayers can subtract from their income.
- Itemized Deductions: Specific expenses that can be deducted, such as mortgage interest, state and local taxes, medical expenses, and charitable contributions.
Different Types of Deductions
Standard Deduction
The most common deduction, often updated annually to keep pace with inflation. For example, in 2023, the standard deduction for a single filer might be $12,550, which means $12,550 is subtracted from gross income before calculating taxable income.
Itemized Deductions
These include a variety of specific deductible expenses such as:
- Medical Expenses: Over a certain percentage of AGI.
- Mortgage Interest: On qualified homes.
- Charitable Contributions: Subject to various limits.
- State and Local Taxes (SALT): Capped at $10,000 per year.
What Are Exemptions?
Exemptions refer to specific portions of income that are not subject to tax. Historically, there were personal exemptions and exemptions for dependents, which served to reduce taxable income. However, under the Tax Cuts and Jobs Act (TCJA) of 2017, personal and dependent exemptions have been eliminated for the tax years 2018 through 2025.
Types of Exemptions
- Personal Exemptions: Previously allowed taxpayers to deduct a specific amount for themselves and their dependents.
- Dependent Exemptions: Allowed additional deductions for each dependent claimed.
Special Considerations
Changes Under the TCJA (2017)
The Tax Cuts and Jobs Act of 2017 significantly altered the landscape for deductions and exemptions:
- Elimination of Personal Exemptions: Personal exemptions were eliminated, increasing the importance of the standard deduction.
- Increased Standard Deduction: The TCJA nearly doubled the standard deduction.
- SALT Deduction Cap: Capped at $10,000 annually, reducing benefits for taxpayers in high-tax states.
Examples
Example 1
Standard Deduction Calculation:
- A single taxpayer with a gross income of $50,000.
- Standard deduction for single filers: $12,550.
- Taxable Income: $50,000 - $12,550 = $37,450.
Example 2
Itemized Deduction Calculation:
- Medical expenses: $5,000 (over 7.5% of AGI).
- Mortgage interest: $10,000.
- SALT: $10,000.
- Total itemized deductions: $25,000.
- Taxable income: Gross income - total itemized deductions.
Comparisons
Deductions vs. Credits
- Deductions reduce the income subject to tax.
- Credits reduce the amount of tax owed directly.
Deductions vs. Exclusions
- Exclusions refer to income that is never subject to tax.
- Deductions are subtracted from income to reduce taxable income.
Related Terms

Summary
Deductions and exemptions play vital roles in determining taxable income, offering tax relief to individuals and businesses. While deductions lower taxable income by accounting for specific expenses, exemptions (though currently suspended) provided allowances for taxpayers and dependents. Understanding these concepts is essential for effective tax planning and compliance.
