Deduction

Definition

A deduction is an amount allowed to taxpayers by the Internal Revenue Code (IRC) to reduce their gross income or adjusted gross income (AGI). Deductions are crucial in determining a taxpayer’s taxable income and ultimately the amount of tax they owe. By subtracting allowable deductions, individuals and businesses can lower their taxable income, effectively reducing their tax liability.

Key Types of Deductions

Itemized Deductions: Specific expenses that taxpayers can report on their tax returns incurred during the tax year. Common itemized deductions include mortgage interest, state and local taxes, charitable contributions, and medical expenses.
Standard Deduction: A fixed dollar amount that reduces the income on which you’re taxed. Filing status determines the amount of the standard deduction.
Marital Deduction: An unlimited deduction available to married couples for property transferred to a spouse, either during their lifetime or at death, which is not subject to estate and gift taxes.

Examples

Medical Expenses: If total unreimbursed allowable medical expenses exceed 7.5% of AGI, they can be deducted as an itemized deduction.
Mortgage Interest: Interest paid on a mortgage for a primary or secondary home can be deducted if taxpayers itemize their deductions.
Charitable Contributions: Donations to qualifying charitable organizations can be deducted when itemizing.
Business Expenses: Businesses can deduct costs that are ordinary and necessary for the operation of the business, such as equipment, office supplies, and salaries.
